Why Termite Damage Is a Queensland Problem

Almost all of populated Queensland sits in the highest termite risk category in the country, and the reasons are climatic. Subterranean termites need warmth and moisture, and this state supplies both for most of the year. Colonies remain active through winter here in a way they do not further south, which means the damage accumulates over twelve months annually and not six. A colony working undetected in a Brisbane house does considerably more in three years than the same colony would in Melbourne. That difference is why inspection intervals recommended nationally are the minimum here, not the norm.

The housing stock compounds it. Queensland has an enormous number of timber framed houses raised on stumps, with a subfloor space that is warm, dark, sheltered and frequently inaccessible. Timber posts, stumps, deck frames, fence posts and stored timber all provide a route from the soil into the building. Where a house sits on a concrete slab the risk changes shape without disappearing, since termites exploit cracks, expansion joints and service penetrations to reach the frame above. Slab houses simply hide the entry route more effectively, which delays discovery. Neither construction type is safe by default.

What separates termite work from every other repair trade is the sequencing. On a leaking roof, the repair is the answer. On termite damage, the repair is the last step, and doing it first is the most expensive mistake available. New timber installed while a colony is still active becomes food, and the household has paid twice for the same problem. This point is worth more than everything else on this page. It is also the point most often skipped when a household is anxious to see the damage gone.

The second thing worth knowing early is that the damage found on inspection is usually a fraction of the damage present. Termites work inside the timber and leave the outer skin intact, which means a wall stud can be almost completely consumed while looking entirely ordinary. Quoting a repair before linings come off is guesswork, and any contractor presenting a fixed price without opening anything up is either optimistic or has built in a margin the owner cannot see. Both outcomes cost the owner, and only one of them is visible at the time of signing.

The Species Doing the Damage in Queensland

Several species matter here and they behave differently, which affects both treatment and how the damage presents. Coptotermes acinaciformis is the most economically destructive termite in Australia and is widespread across Queensland. It builds large colonies, frequently nests inside the base of a tree or within a building itself, and can forage many metres from the nest, which is why the source is often not on the affected property at all. A neighbour's tree stump or a nest under a nearby slab can supply a colony working through your wall. That is worth knowing before assuming your own yard is the problem.

Schedorhinotermes species are also common through the southeast and are notable for the speed at which they can damage timber once established. They are frequently found in stumps, retaining wall timbers and fence posts before moving into a building. Nasutitermes species attack timber in service as well and tend to be more visible, building conspicuous arboreal nests, though they are generally considered less destructive to sound structural timber. Their visibility is a small mercy, since activity that can be seen is activity that can be dealt with early.

In the tropical north Queensland has a species most of the country does not deal with. Mastotermes darwiniensis, the giant northern termite, is restricted to northern Australia and is regarded as the most destructive termite species in the world. It attacks a far wider range of materials than other species, including living trees, rubber, leather and plastics, and colonies can be very large. Property owners north of roughly the Tropic of Capricorn should treat any suspected activity as urgent. Timeframes that would be acceptable further south are not appropriate where this species is present. Damage accumulates faster and across more materials.

Identification matters because it changes the treatment approach. A licensed technician will collect specimens and identify the species before recommending a system, and a report that does not name the species has skipped a step. Species also affects the likely nest location, which affects how quickly the colony can be eliminated and therefore when repairs can safely begin. Ask for the species to be named in the written report.

Treat First, Repair Second, and Why the Order Matters

This is the section to act on. Structural repairs should not begin until the colony has been dealt with and the treating technician is satisfied that activity has ceased. Installing fresh untreated timber into a building with an active colony puts new food directly in front of the termites, and pine framing is considerably more palatable to them than the aged hardwood it often replaces. Owners of older hardwood framed houses sometimes find the second round of damage arrives faster than the first, for exactly that reason.

The sequence that works is straightforward. A licensed technician inspects and identifies the species and the extent of activity, a treatment system is installed and given time to work, activity is confirmed as eliminated through follow up inspection, and only then does the building work start. Baiting systems in particular need time, since the whole point is that workers carry the bait back to the nest, and rushing that stage defeats it. Depending on the system and the season, that can mean several weeks between treatment and a safe start date. Building that into the programme from the outset avoids a stalled job.

Owners understandably want the damage gone quickly, and a builder eager to start will sometimes agree to work around an ongoing treatment. That can be reasonable for non structural cosmetic work in an unaffected part of the house. It is not reasonable for the timbers the termites are actually in, and any contractor who offers to replace an infested bearer while the colony is still live is either not thinking it through or is not being straight with you. Either way it is a reason to get a second opinion before committing.

Coordination between the two trades is what makes this work. The pest technician and the builder need to be talking, because the builder will be opening up exactly the areas the technician wants to inspect, and material removed during repairs can carry live termites to another part of the property or to a neighbouring one. Agreeing who does what and in what order at the start saves a great deal of frustration. Put both parties in the same email thread at the beginning. It costs nothing and it prevents the most common failure on these jobs.

Where treatment and repair are being arranged separately, ask the technician in writing when it is safe to begin building work and what evidence that judgement rests on. It gives the builder a clear start point and it gives the owner a document if activity reappears afterwards. Treatment work itself sits under termite inspection and treatment. Keep that correspondence with the rest of the property records.

Why You Should Not Disturb Active Workings

The instinct on finding termites is to spray them, break open the mud tubes and clear the area out. That instinct is wrong and it can turn a manageable problem into a longer and more expensive one. Termites respond to disturbance by retreating and sealing off the damaged section, and the colony simply resumes elsewhere in the building where nobody is looking. The activity has not stopped, it has only become invisible again, which is considerably worse than knowing where it was.

Baiting depends on live workers foraging in an accessible location. If the workings have been sprayed with a supermarket insecticide, the affected workers die locally and the colony abandons that route without the active ingredient ever reaching the nest. The technician then has to find where the activity has moved to, which can take weeks and sometimes means the original opportunity is gone. A colony that has been disturbed once tends to be harder to bait a second time. Nothing is gained by the intervention.

Mud tubes and workings are also evidence. A technician reads the direction of travel, the moisture content, the species and the age of the activity from what is physically there, and that reading shapes the treatment plan. A tube knocked off a stump destroys information that was useful. Photograph anything you find and leave it physically intact for the technician. A phone photo costs nothing and preserves what the tube was telling you.

The correct response is to leave everything exactly as found, photograph it, close the area up and call a licensed technician. If a wall lining has been opened and live termites are visible, tape the sheeting back over it. Nothing is gained by waiting a few days and a great deal is lost by interfering. Restrict access to the area if children or pets are around, and otherwise leave it alone.

Why Termite Damage Stays Hidden

Termites avoid light and moving air, so they eat the inside of a timber member and leave a thin outer veneer intact. A hardwood bearer can be reduced to a shell a couple of millimetres thick while presenting a completely normal surface. This is the single reason termite damage assessments run so far over initial expectations, and it is why the ranges on this page are wider than any other repair page on this site. Owners should go into the process expecting the scope to grow once opening up begins.

Where the surface is painted, the illusion holds even longer. A painted skirting board, architrave or door jamb can be entirely hollow behind an unbroken paint film. The film flexes slightly under finger pressure and produces the blistered or rippled appearance that is one of the classic signs, though by the time it appears the timber underneath has usually gone. Running a finger along a skirting and feeling it give slightly is worth following up. So is a skirting that sounds different from the one in the next room.

Modern construction hides it differently. Plasterboard lined walls conceal the frame completely, and a stud can be consumed without any external evidence until the lining itself starts to deflect or a cornice line moves. In an older Queenslander with vee jointed timber linings the signs tend to show earlier, since the boards themselves are timber and will show damage directly. That is one of the few advantages older construction has here. Damage that shows early is damage that gets caught.

Moisture drives where they go. Termites need humidity and they follow it, which means a leaking shower, a blocked downpipe discharging beside a wall, a poorly drained subfloor or a dripping air conditioning condensate line all create the conditions they prefer. When damage is found, the moisture source is usually within a couple of metres of it and fixing that source is part of the repair. Ask the inspector to identify it alongside recording the damage, since the two are the same problem.

Warning Signs Worth Checking

Mud tubes are the most definitive sign and the easiest to recognise, being the pencil width earthen tunnels termites build to travel over hard surfaces. They are pencil width earthen tunnels running over concrete, brickwork, stumps or piers, built so termites can travel from soil to timber without exposure to open air. Any tube found on a stump, a pier or the outside of a slab edge should be left in place and reported to a technician and never knocked off. Tubes can also run up the inside face of a stump where they are only visible from underneath.

Inside the house the signs are subtler. Blistered or rippled paint on skirtings, architraves and door frames, a door or window that has suddenly become tight, floors that feel soft in one area, and hairline cracking that has appeared in cornice lines are all worth investigating. A hollow sound when tapping skirtings with a knuckle along their length is a genuinely useful check and takes a few minutes a room. Compare rooms against each other, because the difference between a sound skirting and a hollow one is obvious once you have heard both. Wet areas and external walls are where to start.

Swarming is seasonal and unmistakable. Winged reproductives leave the nest in large numbers, typically on humid evenings in the warmer months, and they are attracted to lights. Discarded wings on windowsills, in sinks or around light fittings mean a colony has flown, and while it does not necessarily mean the colony is in your house it does mean one is close by. An inspection after a swarm is a reasonable precaution.

Outside, check the base of stumps and piers, deck posts, fence posts, retaining wall timbers, stored firewood and any timber in contact with the ground. Those are the places activity is found first on most Queensland properties. Trees and stumps in the yard are also common nest sites, and a stump left in the ground after a tree removal is worth grinding out for exactly this reason, which falls under stump grinding and removal. A stump left in the ground is a nest site sitting metres from the house.

None of this replaces a proper inspection. A homeowner can find obvious activity and cannot rule it out, and the areas that matter most are the ones hardest to see. Annual inspection to AS 4349.3, the Australian Standard covering timber pest inspections, is what actually keeps ahead of the problem. The standard also governs what an inspector must report on and what limitations they must record.

Assessing the Extent Before Anyone Quotes

Establishing how far the damage runs is a distinct job from treating the termites and from repairing the building, and it is worth paying for properly. A timber pest inspection with a written damage report costs $300 to $700 and gives a documented basis for everything that follows, including any conversation with a builder, an engineer or a buyer. Without it, every subsequent quote is based on a different understanding of the problem. It is the cheapest document in the whole exercise.

Tapping and probing remain the core techniques and they work well in accessible areas. A sounding tool along a skirting, a bearer or a stud produces an obvious change in tone where the timber is hollow, and a probe confirms it. The limitation is access, since a wall lined with plasterboard and a subfloor with six hundred millimetres of crawl space both restrict what can be reached. The report should record where access was restricted, and those restrictions are as important as the findings. An area that could not be inspected has not been cleared.

Instruments extend the reach. Moisture meters detect the elevated humidity termites create inside a wall cavity, thermal imaging picks up the temperature differences produced by an active nest or by moisture, and borescopes allow a small hole to be drilled and the cavity viewed directly. Movement detecting devices designed for termite work are also used. None of these see through walls in the way people imagine, and each one narrows the search without settling it. Treat any inspector claiming a device can definitively map damage inside a wall with some caution.

Opening up is what finally establishes extent. At some point linings come off, floor coverings lift and the frame is exposed, and that is when the real scope emerges. A sensible approach is to price the repair in two stages, with an agreed cost for the investigative opening up and a scope written afterwards. Structural questions at that point may need a structural inspection or a structural engineer depending on which members are involved. Getting that input before the repair is designed avoids reworking a scope that has already been priced.

Subfloor Repairs, Bearers, Joists and Stumps

On an elevated Queenslander the subfloor is where activity usually starts and where the most consequential damage occurs. Bearers and joists carry the floor and the loads above it, and a termite damaged bearer is a structural failure waiting for a heavy enough load. Softness or bounce in a floor, particularly near an external wall, is a common first symptom. It is easy to attribute to age and it very often is not.

Repair means propping the floor, cutting out the affected timber back to sound material and installing new members, either replacing a full length or sistering a new member alongside where the damage is localised. Sistering means fixing a new timber beside the damaged one so the two act together, and the overlap has to be long enough to transfer the load properly, not simply cover the bad section. A short sister bolted over a damaged section looks like a repair and does very little structurally. Ask what overlap is being used and how it is fixed.

Timber stumps damaged by termites are a related problem and frequently found at the same time, since a stump in ground contact is the classic entry route. Where several stumps are affected the work overlaps with restumping, and doing both together is far more efficient than propping the house twice. Broader work of this kind sits within structural repairs. Where the stumps themselves are the issue, the job becomes a restump and should be scoped as one.

Access decides much of the cost. A high set house where a person can work upright underneath is straightforward. A low set house with a crawl space means every cut, every prop and every length of new timber goes in by hand through a restricted opening, which multiplies the labour on identical work. Owners with restricted subfloors should expect quotes at the upper end and should say so upfront.

While the subfloor is open it is the moment to fix the conditions that attracted the termites. Improving cross flow with underfloor ventilation, correcting ground levels, clearing stored timber and getting stormwater away from the building all reduce the humidity termites depend on. Repairing the timber without changing the environment invites a repeat. Doing this work while the floor is already propped and open is a fraction of the cost of returning for it later. It is the best value available on the whole job.

Wall Frames, Studs and Plates

Wall frame damage is the most common structural finding in slab on ground houses and it is also the most concealed. Termites entering at the slab edge move up into the bottom plate, being the horizontal timber the studs sit on, and then into the studs themselves. The bottom plate is usually the worst affected because it is closest to the entry point and holds the most moisture. Damage runs along the plate and not in one spot, which is why these repairs extend further than the visible opening suggests.

Repairing it means removing the lining on at least one side of the wall, propping where the wall is load bearing, cutting out the affected studs and plate, and installing new framing. Load bearing walls need proper temporary support, and where the span or the load is significant an engineer may need to specify it. Non load bearing walls are considerably simpler and cheaper. Establishing which walls are load bearing is a question for the builder or the engineer, not an assumption from the floor plan. Internal walls in older houses are often carrying more than they appear to.

The lining then has to go back, be set and be painted, and that finishing work is a real share of the cost. Matching an existing painted wall is difficult and a patch is usually obvious, so painting a full wall or a full room generally gives a better result. Work of this kind falls under plastering and gyprock repairs followed by interior house painting. Both should appear in the quote, since a scope that stops at the framing leaves the owner with an open wall.

Older Queenslanders behave differently. A hardwood framed house with vee jointed board linings often has framing timber that is far more resistant than modern pine, though resistant is not immune and old hardwood that has been damaged is genuinely difficult to repair without disturbing a lot of finish. The linings themselves are worth salvaging where possible, since matching original vee joint profiles is expensive. A careful carpenter will number boards as they come off. Ask whether salvage and reinstatement is part of the scope.

Roof Timbers, Trusses and Ceilings

Termites reaching the roof frame is the most serious version of this problem and, fortunately, the least common. It usually means the colony has been established for a long time and has travelled the full height of the building through a wall cavity. Damage to trusses, rafters, hanging beams or ceiling joists is a structural matter and needs engineering input. Discovering activity at that height also means everything below it needs inspecting.

Trusses in particular cannot be repaired casually. A truss is a designed structure where every member and every connector plate is doing a specific job, and cutting or modifying one without design input compromises the whole thing. Damaged trusses are generally either replaced or repaired to an engineer's detail, and a certifier will want documentation. Keep that documentation, since it will be requested at resale and by any future insurer. A repaired truss with no paperwork is a problem waiting for a transaction.

Ceiling damage often appears first as a sag or a crack along a cornice, which owners reasonably attribute to settlement or to a roof leak. Where the cause turns out to be termite damage in the ceiling joists or hanging beams, the repair extends well beyond the visible sag. Access through the roof space is usually how the assessment is done. Where there is no practical roof access, part of the ceiling may need to come down to see anything at all. That should be priced as investigative work.

Roof leaks and termite activity travel together often enough to be worth mentioning. Moisture from a leaking roof creates the humidity termites look for, and finding activity in roof timbers should prompt a look at the roof covering, the flashings and the gutters. Addressing roof repairs at the same time removes the condition that allowed it. Access equipment is already on site at that point, which makes the combined job considerably cheaper than two separate ones.

Skirtings, Architraves, Doors and Joinery

Trim work is the most visible termite damage and the least structurally serious, which makes it a good candidate for staged repair once treatment is complete. Skirtings, architraves, door jambs and window reveals are all softwood in most houses and they sit right at the base of walls where termites arrive. They are also usually the first place a homeowner notices anything, which makes them useful as much as vulnerable.

Matching profiles is the practical difficulty on an older house. Skirting and architrave profiles have changed repeatedly over the decades, and a 1930s ogee skirting or a 1970s profile may need to be custom run to match, which costs considerably more than a stock profile off the shelf. Where a whole room is being redone the question resolves itself, and work of this kind sits under skirting board installation and replacement. Ask for a sample of the matched profile before a full run is machined, since getting it wrong is expensive to correct.

Door frames are a common finding and a damaged jamb is more than cosmetic, since the jamb carries the hinges and the strike plate. A door that has become tight or that no longer latches cleanly may have a jamb that has lost its fixing into the frame behind. Replacement falls under door installation and repairs. Check the jamb before the door itself, because the door is usually sound and the frame is not.

Built in joinery takes damage too. Kitchen and bathroom cabinetry, wardrobe frames and built in shelving are frequently affected where they sit against an external wall, and the carcase material used in most cabinetry is highly palatable. Where cabinetry has to come out for wall frame access anyway, replacement work sits with cabinet making and joinery. Removing and reinstating existing cabinetry intact is sometimes possible and worth asking about, since it is far cheaper than replacement.

Flooring is the last of the finish items. Timber floorboards, and the particleboard or plywood flooring used in more recent construction, both suffer, and damage frequently follows the line of a bearer or joist beneath. Replacement and refinishing falls under timber and laminate flooring or floor sanding and polishing depending on whether the boards can be saved. Matching old boards is easier than matching old trim, since a floor can be sanded to blend once the new boards are in.

Decks, Fences, Sheds and Outbuildings

Activity is very often found outside the house first, in structures nobody thinks of as valuable. Deck posts and frames, fence posts, retaining wall timbers, garden sleepers, sheds with timber framing and stacked firewood are all common sites, and they matter as an early warning as much as damaged property. A damaged fence post is cheap. What it is telling you is not.

A colony working in a fence line or a deck is already at the building. Foraging distances are substantial, and the presence of activity anywhere on the property means the house needs inspecting whether or not anything has been seen indoors. Owners who replace a few fence posts and consider the matter closed are frequently the ones who find house damage two years later. Treat activity anywhere on the block as a reason to inspect the house, even where nothing has been seen indoors.

Repair of these structures is straightforward carpentry and the opportunity worth taking is to remove the vulnerability while rebuilding. Steel posts in place of timber, treated timber to the correct hazard level for ground contact, stirrups holding posts clear of the soil, and clearance kept between timber and the ground all reduce the risk substantially. Work of this kind sits within carpentry services. Rebuilding to the same detail that failed simply resets the clock on the same outcome.

Housekeeping does more than most people expect. Timber offcuts stored under the house, firewood stacked against a wall, garden beds built up over a slab edge, mulch piled against stumps and cardboard stored in a subfloor all create conditions termites use. Clearing that material is free and it removes both food and cover. It also restores the visibility an inspector needs, since a subfloor packed with stored goods cannot be properly inspected. That alone is worth the afternoon.

Reinstating a Barrier Breached During Repairs

This is the step most commonly missed and it undoes a great deal of expensive work. Where a house has a chemical soil barrier, the treated soil forms a continuous zone around and under the building, and any excavation through it leaves a gap. Repairs frequently involve exactly that, whether digging out a footing, replacing a stump, running a new drain or trenching for a service. None of those look like termite work, which is exactly why the breach gets forgotten.

A gap in a chemical barrier is not a small thing, because termites find breaches efficiently. A single untreated section beside a newly replaced stump is an open door into a building that the owner believes is protected. The barrier has to be reinstated by a licensed technician after the ground work is complete, and that is a separate visit and a separate cost. Budget for it at the outset at the end.

Physical barriers behave the same way. Stainless steel mesh and graded stone systems installed at the slab edge or around penetrations are continuous by design, and cutting through one during repairs breaks the continuity. Reinstatement needs to be done by someone who understands the system, and the original installer is usually the right call where they can be identified. The durable notice in the meter box will often tell you who installed it and when.

Coordination is the practical answer. Tell the pest technician what building work is planned and when, so reinstatement can be scheduled as the ground work finishes. Ask the builder to flag any excavation, and put reinstatement in the scope as a line item so it does not fall between the two trades. Name the responsible party in writing. This single line has prevented more repeat infestations than any other item on this page.

Where no barrier exists, the completion of repairs is the natural moment to install one. Access is open, the subfloor is clear and the building is already disturbed, and installing a management system at that point costs considerably less than retrofitting it later. It is the single most useful thing an owner can do to avoid repeating the whole exercise. The marginal cost while everything is open is a fraction of what a standalone retrofit would run.

The Durable Notice and Why It Matters

Australian Standard AS 3660 covers termite management for buildings, and one of its requirements is genuinely useful to homeowners and almost universally unknown. Where a termite management system is installed, a durable notice must be fixed in a prominent location, usually inside the meter box or an electrical cupboard, recording what system was installed, the date, the treated zone and when the next inspection is due. It is a requirement, not a courtesy, and a compliant installer will fit one as a matter of course.

That notice is the single most useful document about a house's termite history and it costs nothing to look for. Buyers should check the meter box during an inspection, and owners should check their own, because a great many people have no idea whether their house has a system at all. An absent notice does not prove there is no system, though it usually means nobody has treated the property recently. It is worth five minutes to check before assuming the house is protected.

Chemical barriers have a finite life, and the notice tells you when the treatment was applied so you can judge whether it is still doing anything. A treatment applied fifteen years ago is not protecting the house today, and a household relying on it is unprotected without knowing. Reticulation systems, which are pipes laid around a building to allow chemical to be replenished, need periodic recharging and that too should be recorded. A reticulation system that has never been recharged is a set of pipes doing nothing. Owners frequently do not know they have one.

After any repair or reinstatement work, make sure the notice is updated or a new one fixed. It carries forward to the next owner, it supports a warranty claim on the treatment, and it removes the guesswork for whoever deals with the house next. General information about building standards and the National Construction Code is available through the Australian Building Codes Board, and standards are published by Standards Australia. Photograph the notice and keep a copy with the property file, since notices in meter boxes fade and get painted over.

Management Systems After the Repair

Once the damage is repaired the question becomes how to avoid repeating it, and there are three broad approaches. Chemical soil treatments create a treated zone around and beneath the building that termites cannot pass without picking up the active ingredient. Modern non repellent products are designed so termites do not detect them and carry them back to the colony, which is a substantial improvement on older repellent chemistry. Product life varies and the label and the installer's warranty will state the expected duration. Ask what it is before signing.

Physical barriers are built in and not applied, using stainless steel mesh, graded stone or collars around penetrations to block concealed access. They do not kill termites and they do not expire, and their purpose is to force any approach into the open where it becomes visible during an inspection. They are far easier to install during construction than afterwards. Retrofitting a physical barrier to an existing building is possible in some situations and impractical in many. A technician can advise which applies.

Baiting and monitoring systems place stations in the ground around a property, which are checked periodically and loaded with bait when activity appears. The bait is carried back and eliminates the colony. Baiting is slower than a soil treatment and it addresses the colony itself, which makes it a good fit where the nest cannot be located. The stations need ongoing monitoring, so it is a service arrangement, not a one off job. Owners who stop the monitoring lose the protection.

None of these removes the need for inspection. Annual inspection to AS 4349.3 is the recommendation for most Queensland properties, and six monthly is sensible in high pressure areas or where there is a history of activity. The system reduces risk and the inspection catches what gets through, and ongoing pest control arrangements usually bundle the two. Ask what the inspection covers and what limitations apply to it.

Licensing, Two Trades and Who Does What

Termite work in Queensland involves two separately licensed activities and owners regularly assume one person covers both. Pest management technicians must hold a licence issued by Queensland Health to apply pesticides, and the licence is specific to the classes of work covered. Information is available through Queensland Health. This differs from the arrangements in some other states, which is worth knowing if you are dealing with an interstate operator.

Building work is licensed separately by the Queensland Building and Construction Commission, and any residential building work worth more than $3,300 in labour and materials needs an appropriately licensed contractor. Structural termite repairs will exceed that threshold in almost every case. Licences can be checked free on the public register through the QBCC. Confirm the licence class actually covers structural building work and not a narrower trade category.

Some businesses hold both and manage the whole job, which has genuine advantages in coordination. Many do not, and there is nothing wrong with engaging a technician and a builder separately provided somebody is managing the sequence. What causes problems is each assuming the other has dealt with something, particularly barrier reinstatement and the timing of when repairs may begin. Nominating one party to coordinate, even informally, removes most of that risk. It is usually the builder, since they control the programme.

Above the QBCC threshold the Queensland Home Warranty Scheme premium applies, and the contractor pays it before starting with a notice of cover issued to the owner. Structural defect cover runs longer than non structural cover, and termite repairs to framing are structural by definition, which makes the notice worth filing carefully with the treatment records and the durable notice. Those three documents together are what a future buyer or insurer will want to see.

Why Home Insurance Excludes Termite Damage

Almost every home building policy in Australia excludes damage caused by termites, and owners discover this at the worst possible moment. The reasoning insurers apply is that termite damage develops gradually over months or years and is preventable through inspection and maintenance, which places it in the same category as rot and wear rather than as a sudden event. Whether that reasoning is fair is beside the point for a household facing a repair bill.

That exclusion is close to universal and it is not usually negotiable. A small number of policies offer limited termite cover as an optional extra or under specific conditions, and the terms are generally narrow. Owners who believe they are covered should read the product disclosure statement, since the wording is where this is decided. Call the insurer and ask the question directly if the policy is ambiguous, and get the answer in writing.

There are narrow situations where a claim may still be worth exploring. Where termite damage causes a sudden collapse, some policies respond to the resulting damage while still excluding the termite damage itself. Where a recent pre purchase timber pest inspection failed to identify obvious activity, there may be a claim against the inspector's professional indemnity instead of the home policy. That is a different avenue with different time limits, so raise it promptly, before the repairs are finished.

The practical consequence is that the annual inspection is doing the job insurance does elsewhere. A few hundred dollars a year against repairs that routinely run into five figures is straightforward arithmetic, and keeping the reports also demonstrates maintenance if any other part of a claim is ever questioned. Consumer protections relating to services and contracts are administered federally by the Australian Competition and Consumer Commission. Queensland complaints about traders go through the Office of Fair Trading.

Moisture, the Underlying Cause Nobody Fixes

Termites need moisture and they go where it is, which means almost every case of significant damage has a water problem sitting underneath it. Finding and fixing that source is part of the repair and it is the part most commonly left out of a scope, because it belongs to a different trade and nobody has been asked to look. Ask for it explicitly and it will usually be found quickly.

The usual suspects are consistent. A leaking shower or bath waste, a downpipe discharging beside the building, a blocked or absent stormwater connection, a leaking tap or pipe under the house, an air conditioning condensate line dripping into the subfloor, and ground levels that have crept up so soil sits against the slab edge or the bearer line. Any one of those creates a damp zone that termites will find. Several together make a property genuinely attractive.

Each of those has a straightforward fix and each is cheap relative to the damage it enables. Getting stormwater away from the building falls under stormwater drainage plumbing, persistent wet ground can be dealt with through French drain and subsoil drainage installation, and a wet area that has been leaking into a wall usually needs bathroom waterproofing rather than only new tiles. A shower that has been leaking behind the tiles for years is one of the most common sources of the moisture that draws termites into a wall frame.

Ventilation is the other half. A subfloor with restricted airflow holds humidity for weeks after rain, and lattice, solid enclosure, built up garden beds and stored goods all reduce it. Where the linings have come off and the subfloor is open anyway, improving ventilation and correcting ground levels costs very little on top of work already happening. Missing that window means paying for access twice.

Where a repair scope makes no mention of the moisture source, ask about it directly. A builder who has identified why the termites chose that particular wall is telling you something useful, and one who has not may be about to install new timber into exactly the same conditions. It is a fair question and a good contractor will have an answer ready.

What Actually Drives the Cost

Extent is the obvious driver and it is genuinely unknowable at the start, which is why the ranges on this page are so wide. What can be estimated is the type of member affected, and that produces a rough hierarchy. Trim and joinery is cheap, non load bearing framing is moderate, load bearing framing and subfloor members are expensive, and roof structure is the most expensive of all. Knowing which category a property falls into gives a realistic starting expectation before any quote arrives.

Access multiplies everything. A subfloor a person can stand in, a wall that can be opened from a garage side, and a roof space with a proper access hatch all keep costs sensible. A six hundred millimetre crawl space, a wall that has tiling on both sides, or a roof space with no practical access turn identical repairs into much larger jobs. Mention access honestly when posting the job, since discovering it on the day produces a variation.

Finishing is a bigger share than owners expect. Removing a lining, replacing framing and putting the lining back is only half the job, because it then needs setting, sanding, painting, new skirting, new architrave and a floor covering reinstated. On trim heavy older houses with custom profiles, the finishing can approach the framing cost. Owners frequently budget for the structural work and are caught out by the finishing. Ask for both to be itemised separately.

Engineering and certification add cost where structural members are involved and they are not optional. An engineer's detail for a repaired truss or a modified load bearing wall protects the owner, satisfies a certifier and matters at resale. Trying to avoid it produces a house with undocumented structural repairs, which is a problem deferred to the next transaction. The cost of doing it properly is small against the cost of unwinding it later.

Living arrangements are the last item. Substantial repairs mean rooms out of use, dust, noise and sometimes services disconnected, and where a kitchen or bathroom wall is involved the household may need to move out for a period. That cost is real and it is not covered by insurance for termite work, so it belongs in the budget from the start. Ask the builder for a realistic programme and not a best case one.

What to Look Out For

Watch first for anyone offering to repair termite damage before treatment has been completed. It puts the steps in the wrong order rather than simply doing them quickly, and it wastes the owner's money, and a contractor proposing it either does not understand the problem or is prioritising getting started. Ask when the treatment was carried out, by whom, and what evidence exists that activity has stopped. A vague answer to any of those three is a reason to pause. The technician should be able to supply a completion report and a follow up inspection result.

Be sceptical of a fixed price quoted before anything is opened up. Concealed damage is the defining feature of this work and nobody can see through a wall. A quote structured with a cost for investigative opening up and a scope written afterwards is more honest than a single figure that will be revised twice. Contractors who work in this field regularly will propose that structure themselves. Ask what the investigative stage costs and what it will establish. It should be a modest fixed sum.

Watch for scopes that stop at the visible damage. Termites do not respect the edge of a room, and a wall frame repaired to the point where the lining was cut, with the adjoining section left because it was not exposed, produces a repeat visit. Ask how the boundary of the repair was determined and what confirmed the adjoining timber is sound. Sounding or probing beyond the damaged section is the minimum, and it should be recorded.

Check that barrier reinstatement is in the scope wherever ground works are involved. This is the item that falls between the builder and the pest technician most often, and the consequence is a treated house with an open route into it. It should appear as a line item with a named party responsible. If neither the builder nor the technician will own it, that is a problem to resolve before work starts. Nobody discovers an unreinstated barrier until the termites do.

Finally, be wary of treatment offered by someone who has not identified the species, and of building work quoted by someone who cannot produce a QBCC licence number. Both are cheap to verify. Both are expensive to get wrong, and termite repair is a field where the cost of a poor job is not the wasted money but the second round of damage. Do not pay a deposit beyond the statutory limit and do not pay in full before the work is complete and inspected.

How to Get Useful Quotes

Start with the inspection report and give it to everyone quoting. A timber pest report identifying the species, the locations of activity and the observed damage gives every contractor the same starting point, and it immediately exposes a quote that has priced only part of the problem. Without it, three quotes will describe three different jobs. Sharing the report also lets contractors tell you quickly whether the work suits them.

Say clearly where the treatment sits. Whether it has been carried out, by whom, when, and whether the technician has confirmed activity has ceased. This determines when a builder can start and it is the first question a good one will ask. If treatment has not happened yet, say so, since a builder can still quote and schedule around it. Being upfront about the sequence gets you contractors who understand it.

Describe the house in the terms that drive the cost. Slab on ground or elevated, timber or steel framed, the age, the subfloor clearance if there is one, whether the affected wall is load bearing, whether it is tiled, and how the roof space is accessed. Photographs of the damage and of the affected area help, as does a shot of the meter box showing any durable notice. Include the date the damage was first noticed, since it helps establish how long activity has been running.

Ask each quote to itemise a specific list. What has been assumed about concealed damage and what allowance carries it, whether engineering is included or excluded, who reinstates any barrier disturbed by the work, what finishing is included through to paint and floor coverings, whether the moisture source has been identified and who is fixing it, what the workmanship warranty covers, and whether a notice of cover under the home warranty scheme will be issued. A quote that answers all of those can be compared with another that answers them. A single figure cannot.

Expect variations and set up how they are handled before work starts. Deck and termite repairs generate more variations than any other domestic work, and a contract requiring variations to be documented, photographed and approved in writing before proceeding protects both parties. A contractor who raises that themselves is telling you something useful about how they operate. Ask for photographs to accompany any variation, since that is the evidence the extra cost rests on.

Buying, Selling, Rentals and Body Corporate

Anyone buying an older Queensland house should commission a timber pest inspection to AS 4349.3 alongside the building inspection, and treat it as essential. The inspector will note where access was restricted, and those restrictions matter, since a report that could not access the subfloor has not cleared the subfloor. Read the limitations section as carefully as the findings. Where access was restricted, consider whether it can be improved and the area re-inspected before settlement.

Sellers are generally better off knowing before a buyer does. Damage identified in a buyer's report during a cooling off period produces either a price reduction or a lost sale, and neither is as good as having the position documented and priced in advance. Where repairs have been done, keeping the treatment records, the durable notice, the engineer's details and the QBCC paperwork together makes the house considerably easier to sell. A documented and repaired history is a far better position than an undocumented clean one.

For rental properties the lessor is responsible for maintaining the premises in good repair, and structural termite damage is a maintenance matter rather than a tenant one. Tenants who see mud tubes, discarded wings or damaged skirtings should report it in writing with photographs immediately, since delay allows damage to accumulate. Lessors have a strong incentive to act quickly given the absence of insurance cover. Delay converts a manageable repair into a structural one at the owner's expense.

In a community titles scheme the building structure is usually common property, which makes structural termite damage a body corporate responsibility, while damage to fixtures and contents inside a lot generally sits with the owner. Many schemes hold ongoing pest management contracts covering the whole complex, and an individual lot owner arranging their own treatment may create a gap in that coverage. Contact the body corporate manager before booking anything, and where a pre purchase inspection is being arranged on a unit, a building inspection covering the common property is worth requesting as well.
