Security Door and Screen Repair Services SA 2026 - Complete Cost Breakdown

Security Door and Screen Repair Costs in South Australia for 2026

Security screens are one of the few things on an Australian house that almost everybody has and almost nobody maintains. They sit in the weather every day, carry a door that gets slammed several thousand times a year, and then surprise their owners by dragging on the threshold or refusing a key.

The good news is that the repairs are cheap relative to replacement. Hinge work across South Australia in 2026 runs $120 to $320, a door closer $140 to $340, a lock barrel or handle $150 to $420, and rollers and track on a sliding screen $180 to $480. Those four cover the large majority of faults and all of them are an hour or less of work. Replacing a whole security door runs $650 to $1,900 by comparison, so the economics favour repair heavily wherever the frame is still sound.

Mesh is the item that sits between the two. Re-meshing an ordinary hinged flyscreen door is $280 to $750 and straightforward, while replacing a structural security mesh is $450 to $1,100 because the material has to be re-tensioned and clamped into the frame correctly to retain its rating. On an older door, that cost gets close enough to a new one that the comparison is worth making properly instead of assuming repair is cheaper.

South Australia adds two local factors to all of this. The metropolitan coast from Semaphore through Glenelg to Brighton, and the whole of the Yorke and Eyre Peninsulas, puts salt onto aluminium and steel continuously, and corrosion at the bottom rail is the single most common reason an otherwise sound door reaches the end. And a great deal of the Adelaide Hills sits in a designated bushfire prone area, where screens are part of the building fabric that keeps embers out rather than just insects.

Common Faults and What Actually Causes Them

Five faults account for most of the work in this category, and knowing which one you have tells you roughly what it should cost before anybody quotes. Each of the five maps onto a single replaceable component, which is why this trade is unusually forgiving of a well-informed customer.

A door that drags on the threshold or catches at the top corner has dropped, and that is nearly always hinges instead of the frame. Security doors are heavy, the hinges carry that weight through thousands of cycles a year, and the fixings work loose in the frame over time. Tightening them buys a little time and replacing them properly buys years. A door that slams or fails to latch has a closer problem, since the closer controls the speed and the final pull into the latch, and they wear out on a fairly predictable cycle of five to ten years in this climate.

A key that turns stiffly or not at all is more often than not the barrel rather than the whole lock. Dust, salt and heat all shorten a barrel life, and in the Mid North and the Mallee the fine dust that gets into everything will seize a cheap barrel within a few years. A sliding screen that jumps its track or takes real effort to move has worn rollers, grit packed into the bottom track, or both, and the grit is usually the cause of the roller wear , not the other way around.

Mesh damage divides neatly into two separate kinds. Punctures and tears from pets, hail, a stray cricket ball or somebody leaning a ladder are cosmetic on a flyscreen and security-relevant on a structural screen. Sagging across the middle of a large panel means the tension has gone, which on a security screen matters because the rating depends on the mesh being held properly in the frame.

The one that catches people is corrosion at the bottom rail, because it is the hardest to see and the most terminal. Water sits in the bottom channel of a door frame, salt accumulates in it, and the aluminium corrodes from the inside out. By the time it shows as blistering or a white powdery bloom the rail has generally lost structural integrity, and no amount of component replacement will give you a sound door. Checking that corner with a thumb once a year takes ten seconds and tells you when the clock is running down.

Hinge, Closer and Alignment Repairs

Hinge and closer work is the cheapest and most satisfying repair in this category, because a dragging door that has annoyed somebody for two years is commonly forty minutes of work. It is also the repair most often skipped in favour of quoting a new door, which repays knowing before anybody arrives.

Replacing hinges runs $120 to $320 depending on how many and whether the fixing holes in the frame have been stripped. Where they have, the repair involves either moving to a larger fixing or inserting a threaded insert, which is why the range has an upper end. On a heavy security door the hinges should be rated for the weight, and the commonest cause of repeat failure is a lightweight hinge fitted to a door it was never meant to carry.

Door closers wear predictably and the symptoms are recognisable. A closer that lets the door slam has lost its hydraulic damping and cannot be adjusted back. One that fails to pull the door fully into the latch has lost spring tension. Both mean replacement instead of adjustment, at $140 to $340. Whitco closers have been the standard fitting on Australian security doors for decades and replacements are readily available, which keeps that repair cheap and quick.

Alignment is adjustment rather than parts in a good number of cases, and it should be the first thing tried. Striker plates, latch keepers and closer arms all have adjustment built in, and a door that is close to right can routinely be brought back with a screwdriver and fifteen minutes. A tradesperson who proposes a new door without first trying the adjustment has not looked properly, and door repair on the main door behind the screen often resolves what looks like a screen problem.

Lock, Barrel and Handle Repairs

Lock problems feel urgent and are usually cheap. Replacing a barrel or a handle set runs $150 to $420 and most are done on the spot in a single visit.

The barrel is the part that fails and the lock body generally is not. A barrel is a precision mechanism full of small springs and pins, and dust, salt air and heat all degrade it. The symptom progresses in a recognisable way, starting with a key that needs jiggling, moving to a key that needs to be lifted or pushed while turning, and ending with one that will not turn at all. Replacing a barrel at the first stage costs a fraction of dealing with a key snapped off in it later.

Handles on security doors are generally sold as a set including the barrel housing, which is why a broken handle is $150 to $380 instead of $40. Lockwood, Whitco and Austral are the common fittings on Australian security doors and parts are generally available, though some older proprietary handle sets have been discontinued and in those cases the whole lock assembly gets changed to a current pattern.

Keying across multiple doors justifies thinking about while a locksmith is there. Having the security screen, the main entry door and the back door all on one key is a standard service and costs far less done together than as three separate visits, and rekeying existing locks is in most cases cheaper than replacing them. Where the issue is a lost key , not a faulty lock, lock replacement or rekeying both resolve it and rekeying is the cheaper of the two.

A practical note on maintenance, because it extends barrel life in this climate. A dry graphite or PTFE lubricant once a year keeps a barrel working, while general purpose spray lubricant attracts dust and makes the problem worse within months. That distinction matters more in the Riverland, the Mallee and the Mid North than almost anywhere, because the dust load is high and the wrong lubricant turns into a paste.

Mesh Damage and Replacement Costs

Mesh is where the money is in this category and where the difference between a flyscreen and a security screen becomes a cost instead of a label. Re-meshing an ordinary hinged flyscreen door is $280 to $750, while replacing a structural security mesh runs $450 to $1,100.

The reason for the gap is what the mesh is doing. A fibreglass or aluminium insect mesh keeps flies out and is held in a simple spline, so replacing it is a matter of pulling the old mesh and rolling new mesh into the channel. A security mesh is a structural element that has to resist somebody trying to get through it, which means it is woven from stainless steel or made of perforated aluminium sheet and is clamped and tensioned into the frame under controlled conditions. Done wrong it looks fine and performs like an insect screen, which is the worst of both outcomes.

That is why re-meshing a security screen is generally a factory or specialist job instead of a site repair. Systems like Crimsafe, Prowler Proof, Invisi-Gard, SecureView and Amplimesh each use their own clamping method and their own mesh, and the rating only holds when the original method is used with the original material. An operator who offers to re-mesh a branded security screen with generic stainless mesh is selling you something that no longer meets what it was certified to. The frame, the clamping method and the mesh were tested as one assembly, so substituting any part of it leaves you with an untested product. Ask the question directly and judge the answer by how readily it comes.

Pets are the commonest cause of mesh damage and the fix is worth doing properly. A dog that has pushed through a screen once will do it again, so repairing the mesh without addressing the access is a repeat visit. Fitting a pet door into the screen costs less than two mesh repairs and solves the behaviour. For ordinary insect screens across the rest of the house, flyscreen repair and replacement is far cheaper per panel when several are done in the same visit.

Stainless mesh has one maintenance requirement that catches coastal owners out. Marine grade stainless resists corrosion but it is not immune, and salt left sitting on it will eventually produce surface tea staining and then pitting. Rinsing screens with fresh water every few months is all that is needed, and on the metropolitan coast or either peninsula it makes a measurable difference to how long the mesh lasts.

Frame Damage and Realignment

The frame is the part that determines whether anything else repays doing, and it is also the part people assume is fine. Realignment or repair runs $250 to $700 where the frame is recoverable.

Frames go out of true for three reasons and only one of them is the frame itself. The building can move, which is common across the Adelaide plains where reactive clay lifts and drops footings seasonally and a door that binds in winter and clears in summer is telling you exactly that. The fixings can work loose, which is straightforward to put right. Or the frame can be physically damaged, by a forced entry attempt, an impact, or corrosion eating a rail from inside.

Seasonal movement justifies recognising before you pay anybody. If the door bound up after a wet winter and freed itself by February, planing or adjusting it at its worst point means it will be loose and will rattle through summer. The right response on a clay site is adjustment that accommodates the range , not a fix aimed at one extreme, and a tradesperson who knows Adelaide soils will raise that without being asked.

Where the frame has racked but the sections are sound, a repair involves removing it, squaring it and refixing with appropriate packing, which is $250 to $700 depending on whether the opening itself needs making good. Where corrosion has reached the bottom rail the frame is finished, because that rail carries the load and there is no reliable repair for aluminium that has corroded from the inside. Replacement at that point is the honest answer rather than an upsell. The tell is a bottom rail that gives slightly under thumb pressure or shows a white powdery bloom at the corner. Where you find that on one door of a similar-aged set, check the others, because they are usually running to the same timetable.

Sliding Security Door Repairs

Sliding screens are the most used and least maintained item on a great many South Australian houses, particularly on the back of a home opening to a patio. Roller and track repair runs $180 to $480.

Grit is the cause of nearly everything that goes wrong. The bottom track collects sand, leaf litter and dust, the rollers grind it into the track, and the result is a door that gets progressively heavier to move until somebody forces it and the rollers break up. Replacing rollers at $180 to $320 restores it completely, while replacing a worn track adds $120 to $260 and is needed where the rollers have cut a groove into the aluminium.

Doors that lift out of the track are a different fault. On most sliders the panel is retained by adjustment screws that set roller height, and when those drop the panel sits too low and can be lifted clear. That is a security problem as well as a nuisance, because a screen that can be lifted out is a screen that can be removed from outside, and it is a ten minute adjustment to put right.

Handle and lock failures on sliders follow the same pattern as hinged doors but the hardware is different, with a hook bolt or a claw engaging a keeper in the jamb , not a latch. Misalignment between the hook and the keeper is the common complaint, and it is generally the keeper position rather than the lock. The fix is adjustment, and security door lock work covers the cases where the hardware itself has failed.

Maintenance here is genuinely effective and takes five minutes. Vacuum the bottom track, brush out what the vacuum misses, and keep it dry rather than lubricated, because grease in a track collects grit and accelerates exactly the wear it is meant to prevent. Doing that twice a year will roughly double the life of a set of rollers, and on a patio door facing the prevailing weather it is the single most useful thing an owner can do.

Security Window Screen Repairs

Window screens are cheap individually and add up across a house, which makes them the clearest case for bundling work into one visit. Insect screen panels run $80 to $220 each and security window screens $220 to $650 each.

The economics of doing them together are significant. A single screen panel attracts a minimum charge that covers the attendance, so one panel might cost $180 while eight panels done in the same visit come to around $700. Anybody with several damaged screens should count them all before calling, because the marginal cost of the fourth, fifth and sixth panel is small.

Fixed security window screens are a different product from the hinged door and they fail differently. Being fixed, they have no moving parts to wear, so the issues are mesh damage, tension loss, and the fixings or the frame itself corroding. On the metropolitan coast and both peninsulas the fixings are in most cases what goes first, and a screen that rattles in the wind has lost its fixing grip , not its mesh.

Hail is the other cause worth noting in a South Australian guide, because summer thunderstorm cells do concentrated damage and flyscreen mesh punctures readily where a window has survived. After any hail event it is worth walking the house and counting screens, since they tend to be claimable alongside the rest of the damage and are easy to overlook. Standard flyscreen installation covers new panels where the frames are beyond repair.

Security Grilles and Bar Repairs

Fixed grilles and bars are the older approach to window security and a great many Adelaide homes still carry them, particularly in the inner and western suburbs. Repairs to them run $180 to $650 per opening.

The faults are mechanical and the materials are typically steel instead of aluminium, so rust rather than corrosion is the issue. A grille that has rusted at its fixings can usually be removed, treated and refitted, while one that has rusted through its own sections is replaced. Repainting a sound steel grille properly, meaning wire brushing, treating and applying a direct-to-metal coating, costs $150 to $400 per opening and extends its life a good deal.

The important point about grilles and bars is not the repair cost, it is the egress question covered further down this page. A fixed bar over a bedroom window prevents entry and equally prevents exit, and in a fire that matters a great deal. Any grille on a bedroom window should either be removable from inside without a key or be replaced with a modern security screen that provides the same resistance while remaining an escape path. Where glazing has also been damaged in the same opening, window glass replacement is generally quoted separately from the screen.

Where owners are replacing grilles, the cost comparison is in most cases favourable in both directions. A modern security screen at $450 to $900 per window provides comparable entry resistance, looks far better, does not rust, lets air through and does not trap anybody inside. For most houses that is a better outcome than restoring thirty-year-old steelwork. Where the alarm is being reviewed in the same visit, home alarm systems pair sensibly with the screens, and security screen installation covers the replacement side.

Salt Corrosion and Coastal Repairs

This is the section that makes a South Australian guide different, because the state has a very long coastline relative to its population and a great many people live within a few kilometres of salt water. What salt does to aluminium is slow, invisible from outside and eventually terminal.

Salt corrosion on aluminium does not look like rust and that is why it gets missed. It presents as a white or grey powdery bloom, sometimes with surface blistering under paint or powder coating, and it works from the inside of a hollow section outward. The bottom rail of a door frame is the usual starting point because water and salt collect in the channel, and by the time the bloom is visible the section underneath has as a rule lost strength. There is no reliable repair at that stage.

Severity scales sharply with distance from the water. Properties within a few hundred metres of surf at Semaphore, West Beach, Glenelg or Brighton, and along both peninsulas, sit in the worst environment in the state, where ordinary powder-coated aluminium with standard fixings lasts markedly less time than the same product five kilometres inland. Specifying marine grade stainless fixings and a marine grade powder coat costs very little more at the time of purchase and is the single most effective decision available.

Galvanic corrosion is the other coastal problem and it is avoidable. Putting a standard steel screw into an aluminium frame near salt air sets up a reaction between the two metals. That reaction eats the aluminium around the fixing, and the screen comes loose or pulls out of its frame within a few years. Any repair on a coastal property should specify stainless fixings throughout, and it repays checking what a tradesperson is using instead of assuming.

Maintenance here is both simple and genuinely effective. Rinsing screens, doors and tracks with fresh water every two or three months removes the accumulated salt before it can do its work, and in practice that means running a hose over them when you wash the car. Owners who do it get noticeably longer life out of the same product than owners who do not, and it is the clearest example in this whole category of maintenance mattering more than specification.

What the Australian Standards Actually Test

Security screen is a term anybody can print on a brochure, so the only thing that separates a genuine security product from an insect screen in a sturdy frame is testing against the published standard. Knowing what those tests involve makes it much harder to be sold something that merely looks substantial.

The Australian standard for security screen doors and window grilles sets out a series of physical tests that a product has to pass. They include a knife shear test where a blade is drawn across the mesh under load, a dynamic impact test strikes the screen repeatedly with a weighted bag, a pull test checks the mesh and its retention in the frame, and a probe test confirms that no opening can be created. A product that has passed those tests as a complete system, meaning the mesh, the frame, the clamping and the hardware together, is a security screen. One that uses certified mesh in an uncertified frame is not, because the tests apply to the assembly rather than to the mesh alone.

That system point is the one worth carrying into any purchase or repair conversation. Compliance belongs to the whole door as built, which is exactly why re-meshing a branded security screen with generic mesh voids what it was certified to, and why mixing a certified mesh into a frame from a different manufacturer produces something untested. Ask for the test certification for the specific product and ask whether a repair preserves it.

There is also a separate standard covering the installation itself, because a certified door fixed badly into an opening is only as strong as its fixings. That standard addresses how the frame is attached to the building and with what, and it is the reason a security screen installation is more than putting screws through a flange. For products marketed on bushfire performance there is a further set of requirements again, covered in the next section.

Bushfire Rated Screens

A great deal of South Australia sits in designated bushfire prone areas, including much of the Adelaide Hills, the Fleurieu, the Mount Lofty Ranges generally, parts of the Barossa and Clare districts, Kangaroo Island and the Limestone Coast plantation country. In those places a screen is doing a job that has nothing to do with insects or burglars.

In those areas screens stop being an insect or security item and become part of the building fabric that keeps embers out. Ember attack instead of direct flame is what destroys the large majority of houses lost in a bushfire, and embers enter through gaps, vents and openings. A screen with an appropriate mesh aperture over a window or a door is a barrier against that, which is why bushfire construction requirements specify mesh characteristics and frame materials rather than leaving it to preference.

The practical specification is a corrosion-resistant steel, bronze or aluminium mesh with an aperture small enough to exclude embers, in a frame of a material that will not fail in radiant heat. Plastic and fibreglass insect mesh does neither of those things, and a house in a rated area with fibreglass screens has an ember path at every opening. Upgrading screens is one of the cheaper items on a bushfire preparation list relative to its effect, and bushfire rated flyscreen installation is priced separately as its own job.

Where a property is being renovated or extended in a designated area, the requirements apply to the new work as a matter of building approval instead of choice, and the applicable rating for the site determines what is needed. For existing houses there is no retrospective obligation, which means the decision is voluntary, and that is exactly why so many Hills properties still carry fibreglass mesh in an area where it should have been replaced years ago.

A repair question follows from all of this and it justifies asking. If you have bushfire rated screens and one is damaged, repairing it with ordinary mesh removes the protection from that opening entirely while leaving the rest of the house looking protected. Any repair in a rated area should match the original specification, and a tradesperson should be asking you whether the property is in a designated area before quoting rather than after.

Egress, Fire Safety and Children

Security works in both directions and this is the part of the subject that gets least attention until it matters. A screen that stops somebody getting in can equally stop somebody getting out.

Bedroom windows are the specific concern in every house. In a house fire, a bedroom window is frequently the escape route, and a fixed steel grille or a security screen that cannot be released from inside turns that route into a wall. Modern security screens address this with internal release mechanisms on designated egress windows, which hold against entry from outside while opening from inside without a key. If your bedroom windows carry fixed bars or screens with no internal release, that is worth changing regardless of anything else on this page.

Keyed deadlocks on main doors raise the same issue in a different form. A double-cylinder deadlock that needs a key from inside is excellent security and a genuine hazard in a fire or a medical emergency, particularly where children or older residents are involved. The usual compromise is keeping the key on a hook within reach of the door but not reachable from the letter slot or a window, and the fire services across Australia have consistently recommended that approach over removing the deadlock.

Children and screens is the other half of it, and the risk runs the opposite way. An insect screen provides no restraint at all against a child leaning on it, and falls from windows are a recognised and preventable injury in Australian homes. A flyscreen is not a safety device and should never be relied on as one, while a properly fixed security screen or a window restrictor limiting the opening does provide restraint. Where there are young children in an upper-storey room, that distinction repays acting on.

For commercial and multi-residential buildings the requirements are prescriptive instead of advisory, with designated exits having to remain openable and clear. In a strata or community title property, altering anything that affects an exit path is a body corporate matter as well as a building one.

Repair Against Replacement

The decision is usually clearer than people expect and it comes down to the frame, the mesh and the age of the product rather than to how bad it looks. Three questions settle it, and none of them require an opinion from somebody who wants to sell you a door.

Repair is the right call where the frame is square and sound and the fault is a component. Hinges, closers, locks, handles, rollers, tracks and keepers are all replaceable parts and the total of those repairs rarely approaches the cost of a new door. A fifteen-year-old door with a good frame and three failed components is still worth $400 of work rather than $1,200 of replacement.

Replacement wins on value in four specific situations. Those are a corroded bottom rail, a frame racked beyond squaring, a mesh replacement on a product whose certification can no longer be matched, and a non-certified screen in a position that calls for a certified one. The third of those is the one that surprises people, since a $900 re-mesh on an older branded door often sits uncomfortably close to a $1,200 new door that carries current certification and a fresh warranty.

Warranty is part of the comparison and routinely left out of it. A new security door from an established system typically carries a manufacturer warranty of ten to fifteen years on the frame and mesh, while a repair carries whatever the tradesperson offers, which is generally twelve months on the part and the labour. On a door that is already near the end of its life, buying fifteen years of warranty for a few hundred dollars more than a repair is in many cases the better decision.

One practical note on sequencing justifies adding. Where several doors and screens around a house are all of a similar age and one has failed, the others are generally close behind. Replacing them together attracts a better price per opening than replacing them one at a time over three years. It is worth getting the whole house quoted even when only one door is currently a problem.

Adelaide Metropolitan Pricing Variations

Labour rates for this work sit in a narrow band across metropolitan Adelaide, so what varies between areas is the environment the product has been living in and whether the openings are standard sizes. Both of those follow the age of the house instead of its address.

The coastal strip is the expensive one and salt is the whole reason. From Semaphore and West Lakes through Henley, Glenelg and Brighton to Seacliff, screens live in a chloride-laden atmosphere and reach the end of their life years earlier than identical products inland. What follows is that coastal jobs tilt toward replacement rather than repair more often, and that marine grade specification repays paying for instead of optional.

The older inner suburbs cost more for a different reason, which is non-standard openings. Bluestone and sandstone cottages in Prospect, Norwood, Unley, Thebarton and the city fringe have openings that are not modern sizes and commonly not square, which means a replacement door is a custom measure and make rather than a stock size. That difference is a few hundred dollars and several weeks of lead time, and it is also exactly why repair is so often the better value in those houses.

The growth areas north and south of the city are the cheapest and most straightforward. Houses built in the last three decades have standard openings, standard frames, aluminium rather than timber reveals, and good access, so a replacement is a stock item fitted in an hour. The Adelaide Hills sit apart from all of this because the dominant consideration there is the bushfire rating instead of the price, and specification matters more than the hourly rate.

Regional South Australian Pricing Patterns

Regional pricing on screens is unusual in one respect, which is that the product itself often has to come from Adelaide even where the labour is local. That splits the cost in a way most trades do not.

Repairs using stock components are genuinely cheaper in the regional centres. Hinges, closers, rollers, tracks and barrels are held by local hardware and locksmith businesses in Mount Gambier, Port Lincoln, Whyalla, Port Pirie, Murray Bridge and the Riverland towns, so a component repair prices at or below outer Adelaide. Travel applies outside the town boundary, in most cases as a mobilisation charge of $80 to $250.

Anything involving a made-to-measure product changes the picture. Security screen doors and fixed window screens are manufactured to the opening, which in regional South Australia routinely means measured locally, made in Adelaide and freighted out, then fitted on a second visit. That is two trips and a freight component, and it is why a replacement door in Ceduna or Coober Pedy costs noticeably more than the same door in Salisbury. Batching is the answer, so if several openings need doing, having them all measured on one visit and fitted on one return visit is substantially cheaper than doing them separately.

The coastal peninsulas carry the harshest environment in the state for this product. Properties along the Yorke and Eyre Peninsulas, at Port Lincoln, Tumby Bay, Streaky Bay, Wallaroo, Moonta and Port Vincent, combine constant salt with strong wind, and screens there have a shorter life. Marine grade specification is not an upgrade in that country, it is the minimum that makes sense, and fresh water rinsing makes more difference than anywhere else in the state.

Unattended holiday homes add their own pattern on both peninsulas and along the Fleurieu. A screen damaged in a winter blow at Moonta Bay or Normanville is often not noticed for months, and in the meantime the opening is unsecured and weather is getting in. Asking a neighbour or caretaker to walk the house after any significant weather is the cheapest protection available. For the broader trade picture, our South Australian locksmith services hub covers the lock and hardware side statewide.

What to Look Out For in Quotes

This trade has a wide spread between good and poor operators, and the difference shows up in whether they diagnose before quoting. A tradesperson who looks at a dragging door and immediately proposes a new one has skipped the part you are paying for.

Insist on having the diagnosis explained to you. A dragging door is hinges, a slamming door is a closer, a stiff key is a barrel, a binding slider is rollers and grit, and each of those is a component under $500. If the answer is replacement, ask what specifically makes the frame unrecoverable, and the legitimate answers are corrosion through the bottom rail, a frame racked beyond squaring, or certification that cannot be matched on a re-mesh. Each of those three is a real and checkable reason. A general statement that it is old is not.

For a security product instead of an insect screen, certification is the question that matters most and it needs asking in a specific way. Ask for the test certification for the exact model, ask whether it covers the complete assembly , not the mesh alone, and on a repair ask directly whether the proposed work preserves it. Generic mesh into a branded frame does not, and an operator who is vague on this point has answered you.

On getting comparable quotes, the practical approach is to count and photograph everything before anybody arrives. Walk the house, list every door and screen with its problem, photograph each one including a close shot of the bottom rail on the hinge side, and note the openings where you want a security rating instead of just an insect screen. Hand that same list to every operator who quotes. It stops the quote drifting between visits, it lets you batch the work for a better price per opening, and the bottom rail photographs will often tell an experienced operator whether a frame is viable before they attend.

Two further things are worth confirming in writing. First, whether the quote includes removal and disposal of the old door or screen, since that is frequently excluded and is an awkward item to deal with yourself. Second, the warranty terms on both parts and labour, and for a replacement the manufacturer warranty on the frame and mesh separately, because those are usually different periods. Established systems carry ten to fifteen years on the product and that is a real part of the value.

On licensing and verification, screen fitting is not itself a licensed trade in South Australia, though locksmithing is regulated and building work above a threshold requires a licensed contractor. That makes the ordinary checks matter more rather than less. Confirm the business details and any applicable licence through Consumer and Business Services before paying a deposit, keep deposits modest, and be wary of door-to-door sales in this category, which has a long history of it. Brand matters more on this category than on most, because the parts are proprietary. Crimsafe, Prowler Proof and SecureView are the names behind most of the high-tensile mesh screens in Australian homes, and each uses its own clamping and framing system, so a repair generally has to come through an operator with access to that system. On hinged security doors the locking hardware is a different story and usually easier, since Whitco and Lockwood supply the bulk of the latches, cylinders and closers fitted in this country and replacement parts are widely stocked. Identify what you have before you ring anybody, because the answer changes who can help. Where a dispute arises over work already done, the path is conciliation through Consumer and Business Services first, and then a claim in the Magistrates Court of South Australia if that does not settle it.
