Finding Out Why the Board Failed

A weatherboard rarely rots because it was a bad board. Water arrived somewhere it was not meant to, travelled along the path of least resistance and did its damage where it finally came to rest, which means the soft spot you are looking at is usually the end of a chain and not the beginning. Replace the board without finding the entry point and the new timber will be soft again on much the same schedule, generally within five to eight years. Diagnosis therefore belongs at the front of the job instead of being treated as an optional extra, and it costs nothing but a careful walk around the house. The broader cladding services guide for Victoria covers how the different wall systems fail.

The culprits are almost always dull and cheap to put right, which is the good news buried in this section. An overflowing gutter pours water down the wall beneath it for as long as the rain lasts, and no board was ever tested against that. A downpipe split at the back where nobody looks can soak a wall for years. A window with no head flashing lets water in behind the boards every time it rains from the right direction. A deck ledger bolted through the cladding without a flashing does the same thing, permanently. And soil, paving or a garden bed built up against the bottom course keeps the timber damp from below all winter.

Where the damage sits tells you a great deal before anyone touches a tool. Rot concentrated at the bottom course across one elevation points to ground contact or splashback, not to anything wrong with the boards. Damage in a vertical strip suggests a downpipe or a leaking pipe behind. Softness directly under a window says the flashing above it is missing or reversed. Replacing the board without fixing that flashing simply resets the clock.

A patch around a fixing or a penetration means water is getting in at that point, and scattered softness across several elevations is a different message again, which is dealt with further down this page. Victorian conditions shape the pattern more than owners expect. Southwestern elevations take the brunt of the winter weather across most of the state, so that is where paint fails first and boards go soonest. Shaded southern walls stay damp and grow mould, which holds moisture against the paint film even when it is not actively raining. In the coastal districts along the bay, the Bellarine, the Surf Coast and Gippsland, salt accelerates fixing corrosion and the rust stains that follow are often the first visible sign. Inland, through Ballarat, Bendigo and the northeast, the wide temperature swing works joints open and lets water in at cut ends.

Knowing which of those applies to your house narrows the search for the cause considerably. Testing a suspect board is straightforward and worth doing yourself before calling anyone. Press firmly with a thumb or probe gently with a screwdriver at the bottom edge and at both ends, since end grain goes first, and sound timber resists while rotten timber gives and crumbles. Tap along the board and listen for the change from a solid note to a dull one. Mark every soft spot with chalk as you go, including the ones that look marginal.

That chalked elevation gives a carpenter something specific to price from and makes two quotes genuinely comparable. It also stops the count creeping upward once work starts, since everyone agreed on the scope before a tool came out. Fixing the cause is almost always cheaper than the carpentry it prevents. Clearing gutters before winter is the single best value maintenance any Victorian owner can buy, and where the gutters themselves have failed, gutter replacement is worth doing while access is already in place.

Cutting back paving or lowering a garden bed to restore ground clearance costs very little. If an opening has never had a head flashing, fitting one while boards are off is a small addition to the same visit, and window repairs can deal with frames that have also suffered. One thing worth knowing about Victorian weatherboard housing is how much variation there is within a single street. Houses built by different builders in the same year, or extended at different times over a century, routinely carry two or three profiles on the one building, with a rear addition in something quite different from the front. Matching the right one matters more than matching most of them.

Owners often assume a single order will cover the whole house and discover otherwise once the first board comes off the back wall. Checking each elevation separately before ordering avoids that, and it costs nothing but a walk around with a tape measure. Where an addition is involved, the profile change may also mark where the wall build up changes behind the boards. Knowing that before boards come off avoids a surprise at the junction.

Matching Profile and Species

Profile is the shape milled into the board and it is what decides whether new work disappears or announces itself. Victoria has bullnose, rusticated, chamferboard, splayed bevelback and shiplap boards scattered across its housing stock, and the older the house the less likely the profile is anything a timber yard carries. A carpenter who orders the nearest modern equivalent will leave a wall where the shadow line changes partway along an elevation, which is obvious from the street and cannot be undone without replacing the board again. Establishing the profile accurately is the first technical step of the job. Doing that means taking a board off and measuring it instead of guessing from the face. The overall width, the thickness at the thick and thin edges, the shape of the bead or cove and the amount of cover once lapped all matter, and a photograph against a rule is rarely enough for a mill to work from.

Most timber mills that handle heritage work will produce a profile drawing from a physical sample, which is why carpenters take a full length offcut with them. Keeping that sample afterwards is worth doing, because it makes the next repair years later much simpler. A short offcut in the shed has settled many a profile question for a following owner. Custom milling is how a period profile gets matched, and its economics are the most useful thing on this page. The setup charge is the same whether you order ten metres or two hundred.

A mill grinds a cutter to the shape measured off your sample and bills a setup fee for doing it, usually $380 to $1,400 according to how intricate the profile is. That fee lands once, no matter how many metres come off the machine afterwards. Replacing one board therefore carries the entire setup, while replacing ten spreads it across ten. Where a house is likely to need more boards within a few years, running extra length in the same order and storing it flat and under cover is close to free insurance. Species matters less than profile but it is not irrelevant.

Most older Victorian houses carry hardwood, often Victorian ash, messmate or mixed local species, while post war houses are more likely to be treated radiata pine. Hardwood against hardwood keeps the movement and the fixing behaviour consistent across the wall, and any hardwood wants a stain blocking primer underneath so tannin cannot bleed into a light topcoat. Pine is cheaper and straighter but softer, and mixing it into a hardwood wall is acceptable on a painted elevation where nobody will see the difference. On an oiled or stained wall the two will never look alike, so matching the species matters much more there. There are alternatives to solid timber worth asking about. Hardboard weatherboard such as Weathertex is stable, consistent and cuts without producing silica dust, and it comes in profiles that suit many period and mid century houses.

Fibre cement weatherboard such as James Hardie Linea will never rot and is non combustible, which matters in bushfire areas, although thickness and profile have to align with the existing boards. Both are legitimate choices for a painted wall, and the timber cladding fitting page covers species and profile selection in more depth. Salvaged boards are the last option and they suit heritage work particularly well. Reclaimed timber yards across Melbourne and the regional centres carry period profiles recovered from demolitions, and a salvaged board in the right profile can be an exact match with matching patina. The cautions are condition, since a board that has already spent eighty years on a wall may have limited life left, supply, since matching quantities is hit and miss, and paint, since old coatings may contain lead and need handling accordingly.

How a Board Is Replaced

Removing a weatherboard without wrecking its neighbours is the part that separates a carpenter from an enthusiastic owner. Boards overlap, so the damaged board is held by its own fixings and trapped under the one above, and the nails through the board above frequently pass into it as well. The method is to ease the board above gently with wedges or a flat bar, cut or pull the fixings through the damaged board, then slide it out downward. Forcing it splits the board above and turns a one board job into a three board job. That is the commonest way a confident do it yourself repair becomes a carpenter's call out. When only part of a board has failed, splicing is often the better answer.

The rotten section is cut out with the cuts landing on studs so both remaining ends are supported, a new length is fitted between them, and the joints are sealed and finished. A butt joint over a stud is the standard approach and a scarf joint, cut on an angle so the two pieces overlap, sheds water better and is preferred on exposed elevations. Joints should be staggered across an elevation instead of lining up, which reads far better and avoids concentrating movement on one vertical line. Landing joints behind a downpipe or close to a corner hides them further.

Sealing is the step that decides how long the repair lasts and it is the one most often skipped. Seal every surface of a new board, the back and both cut ends included, before it is fixed, since end grain drinks water many times faster than the face. Factory surfaces on a pre-primed board come sealed, and every site cut opens fresh end grain that wants primer before the board goes up. This takes a few minutes per board and it is the single most reliable predictor of whether a repair is still sound in fifteen years. Fixing follows ordinary rules that a general handyman may not know. Lapped boards take a single line of fixings so each one is free to move across its width, and nailing through the new board and the one under it locks the wall and splits it within a summer.

Fixings should be hot dip galvanised as a minimum inland and stainless steel within the salt affected coastal band, since ordinary steel will bleed rust streaks down the face within two winters. Hardwoods need pre-drilling near the ends, and edge distances matter because a fixing too close to the end of a board will split it as the timber moves. None of this adds time to speak of when it is simply how the carpenter works. Finishing brings the repair back into the wall. A new board needs its primer, then two finish coats of a quality exterior acrylic, and a hardwood needs a stain blocking primer underneath.

Matching an existing colour on a wall that has weathered for years is the difficult part, since even the correct original colour code will read brighter than its surroundings. The usual answer is to paint out to a natural break such as a corner, a downpipe or a window reveal, since blending mid wall rarely works, and the weatherboard painting page covers systems and preparation. Timing and weather matter more here than the size of the job suggests. Boards should be on site and acclimatised before fixing, not delivered wet and nailed up the same morning, and paint has minimum application temperatures that rule out some winter mornings in Ballarat and the high country entirely.

A carpenter who says they will come back on a dry day to paint, instead of coating over damp timber, is doing you a favour. Most small board jobs are a day on site plus a return visit for finishing. Asking at quoting stage whether the return visit is included avoids an awkward conversation once the primer is on. Whether the job needs scaffold depends entirely on where the boards are.

Work at the bottom course or anywhere reachable from a trestle is straightforward and cheap, while boards high on a two storey wall or in a gable end need proper access, which commonly runs $900 to $4,500 for a scaffold hire. That single item can cost more than the carpentry itself on a small high level repair. Where upper level boards are involved it is worth checking whether the fascia, the gutters, high windows or an overdue repaint could be done within the same hire, since sharing the access across several tasks is where the real saving lies. Scaffold hire is charged by the week regardless of how much work happens on it.

What Turns Up Behind a Board

The moment a board comes off, the wall stops being a guess. What sits behind it on an older Victorian house is often nothing more than building paper, sometimes nothing at all, and the frame, the bottom plate and the stud ends become visible for the first time in decades. Good carpenters expect that and price for it with a contingency instead of promising nothing will be found. It is worth agreeing before the job starts what happens if the framing turns out to be affected. A rate per lineal metre in the quote turns an unwelcome surprise into a predictable line item. The bottom plate and the lower ends of the studs take the worst of it, which is why so many repairs begin at the bottom course.

Anything running behind the boards ends up at the base of the wall, and where a garden bed or paving has been built up against the house the timber has been wet for years. Replacing a length of bottom plate is routine carpentry at $65 to $180 a lineal metre, but the length cannot be known in advance, which is why a rate belongs in the quote. If the subfloor is also affected, subfloor repairs and ventilation may need scoping alongside. Termite damage is the discovery that changes the job entirely.

Active termite country covers the eastern suburbs, the Dandenong foothills, Geelong and most regional centres, and a cavity will hide serious damage behind boards that look sound from outside. AS 3660 sets out termite management approaches, and a termite inspection is worth arranging on any timber framed house where damage is found. Restoring a visible inspection zone at the base of the wall, clear of soil and paving, is a cheap and permanent improvement while the boards are off. The absence of a wall wrap is the other common finding and it raises a decision. On a one or two board repair there is little to be done about it, since the membrane cannot be introduced piecemeal.

On a larger repair, such as an entire bottom course or a full elevation, installing a vapour permeable membrane behind the new boards is both possible and worthwhile in Victoria's heating climate, adding roughly $9 to $22 a square metre. That is a conversation to have with the carpenter at quoting stage, not after the boards are already off. Photographs are the cheapest insurance on any repair that opens a wall. A dozen pictures of the frame, the bottom plate, any damage found and the flashings before the new boards go on will answer a future building inspector, support an insurance claim and settle any dispute about what the contingency covered.

There is no way to obtain them afterwards. Asking the carpenter to send through photos of anything they find is a reasonable request that most are happy to accommodate. Storing them with the invoice means they can still be found in ten years. Photographs of the frame with the boards off are the ones that prove most useful later.

Lead Paint and Asbestos

Paint applied before the 1970s may contain significant lead, and the inner and middle suburbs of Melbourne are full of weatherboard houses carrying eight or nine coats. Sanding, scraping or cutting that paintwork throws lead dust and flakes into the soil around the house, which matters most in a yard with children or a vegetable bed. The Department of Health sets out how to manage lead safely around the house. This is not a reason to avoid the work, but it is a reason to insist on proper controls. Those controls are ordinary and inexpensive. Drop sheets under the work area to catch debris, wet sanding or vacuum assisted sanding in place of dry power sanding, avoiding heat guns and open flame on old coatings, cleaning up the ground afterwards instead of leaving flakes in the garden, and appropriate personal protection for whoever is doing the work.

A lead safe approach typically adds 15 to 35 percent to the preparation cost on an older house. The lead paint removal page covers testing and safe preparation in more detail. Asbestos is the separate question and it catches owners out because some cladding imitates weatherboard closely. Cement sheet products were made in weatherboard and plank profiles as well as flat sheets, and on a house clad or reclad before 1990 what looks like a timber board may not be one.

Timber sounds and feels different from cement sheet, and a hidden nail or a cut edge usually settles it, but nobody can confirm asbestos by eye. Sending a sample for asbestos testing and inspection removes the doubt for a few hundred dollars. If a test comes back positive, the rules change completely. Removal duties fall under the Occupational Health and Safety Regulations 2017, enforced by WorkSafe Victoria, and unlicensed removal of non friable asbestos is limited to 10 square metres. A few damaged boards may fall within that limit, but the work still requires proper controls, and anything larger needs a licensed removalist. The Environment Protection Authority Victoria regulates disposal, and the waste has to reach a licensed facility and never a general skip.

The asbestos removal page covers the process. How a contractor responds to either question tells you a great deal. A contractor who waves away the build date, offers to dry sand old paintwork without containment, or reckons the sheeting can go in the skip is breaking the law and leaving a hazard on your property. Tradespeople who work regularly on Victorian housing of this age handle both as routine, price them openly and are not put out by being asked. The controls add very little to a small job and their absence adds nothing but risk. The cost of doing it properly is measured in tens of dollars, while the cost of contaminating the soil around a family home is not.

When Repair Stops Making Sense

There is a point at which replacing boards individually becomes the more expensive path, and recognising it early saves a lot of money. The test is not how many boards are bad but how they are distributed. Damage concentrated in one place, such as the bottom course of one elevation or the area under a window, is a repair with an identifiable cause. Softness scattered across several elevations at different heights is telling you something else entirely, which is that the paint system protecting the whole house has failed and water is getting into boards everywhere.

If the paint film is the problem, the answer is preparation and a full repaint instead of a series of board replacements. Patching boards on a house with a failed coating means a carpenter returning every second year for the rest of the time you own the place, each visit carrying its own call out, access and painting costs. A full external repaint costs considerably less than a decade of those visits and it protects every board, not just the few that have already failed. That decision is usually obvious once the pattern is described plainly. Most owners who hear it explained that way choose the repaint and are relieved to stop the cycle of small visits. A full reclad becomes the better value option at a higher threshold again.

Where a substantial proportion of the boards across the house are beyond repair, where the frame has water damage in several places, where the wall has no membrane and no insulation, or where the house is getting an extension and the old cladding will not match the new work, stripping and recladding does everything at once. It also buys access to the frame, the flashings, the wrap and the insulation, all of which are cheap to address while the wall is open and expensive later. The house recladding page sets out that sequence. Movement in the house is a separate signal that changes the order of work. Stepped cracking, doors that stick, sloping floors and gaps opening at the cornices are reporting on the stumps or the footings instead of the cladding, and reactive clay across much of Melbourne's west and north makes that common.

Replacing boards on a house that is still moving is money spent twice, since relevelling the house will open the joints again. Where that is the picture, restumping or reblocking belongs first, and the cladding work follows once the house has settled into its new levels. A written condition report at $250 to $620 settles all of this for a particular house. It identifies the wall type and species, maps the damage, names the likely causes and says whether the sensible answer is repair, repaint or reclad. Owners who skip it often spend money in the wrong order, and owners who get one arrive at quotes knowing exactly what they are buying. It is particularly worth having before a sale, since a buyer's inspector will raise the same questions.

For the cost of a couple of boards it removes the largest uncertainty in the whole decision. It is also a document a buyer's inspector will take seriously if the house goes to market. Insurance is worth a thought where the damage was sudden instead of gradual. A storm that drives a branch through a wall, a burst pipe, an impact from a vehicle or hail damage may be covered by a home policy, while rot that developed slowly over years almost certainly is not, because insurers treat gradual deterioration as maintenance. The practical advice is to photograph everything before touching it and to hold onto the receipts for any temporary weatherproofing, since that is usually covered. The storm damage repairs page deals with the urgent stage, and clearing debris before the camera comes out weakens the claim.

Rules, Overlays and Paperwork

Most weatherboard replacement sits below the thresholds that trigger Victoria's formal building contract requirements, which is one of the reasons it stays affordable. Past $10,000 the job has to be done under a major domestic building contract by a builder whose registration is held with the Building and Plumbing Commission. Below it, a carpenter can take the job on directly under their own arrangements. Where a job grows past that figure, the registration requirement applies, and past $16,000 domestic building insurance is compulsory, with the certificate handed over before any money changes hands. Building permits are rarely needed for like for like board replacement.

Under the Building Act 1993 and the Building Regulations 2018, available on the Victorian Legislation site, replacing cladding with a similar material is commonly exempt, while a change of material, structural work or work in a bushfire prone area may require one. A registered building surveyor makes that call, not the carpenter or the owner. On a handful of boards the question usually does not arise, and on a whole elevation it is worth asking. A surveyor will answer a straightforward query like that quickly. Heritage and neighbourhood character overlays are the control that does apply to small jobs, and Victoria uses them widely. Local controls over the material, profile and occasionally the colour of a street facing wall are common through the inner suburbs and across the goldfields and country towns, from Ballarat and Bendigo to Castlemaine, Maldon and Geelong.

Replacing timber with matching timber in the same profile is generally straightforward, while substituting a different material or profile on a controlled elevation usually requires a planning permit. The free VicPlan report, available from Planning Victoria, sets out the controls on an address, and one call to the council planning counter usually settles what they mean for your elevation. Bushfire attack level can affect what may be used on replacement work in designated bushfire prone areas, which take in a great deal of the hill country beyond Melbourne's eastern suburbs, the ranges north and west of the city, the forested land toward the southwest coast and a broad stretch of the urban fringe. AS 3959 sets the construction requirements, and while a like for like board repair generally carries no new obligation, more substantial work can. The Country Fire Authority publishes guidance on how ratings are determined.

Owners in those districts should know their rating before planning anything larger than a few boards. Consumer protections apply regardless of the size of the job. The Australian Consumer Law provides guarantees that work will be carried out with due care and skill and that materials will be fit for purpose, overseen federally by the ACCC and in this state by Consumer Affairs Victoria. Should something go wrong, put it to the contractor in writing, then to Domestic Building Dispute Resolution Victoria, and to the Victorian Civil and Administrative Tribunal only if that route fails. Keeping the quote, the invoice and photographs makes any of that far simpler.

Costs in Detail

Most carpenters have a minimum charge for a small job, typically $280 to $650, which covers the visit, the setup and an hour or two of work. It is not a markup so much as an acknowledgement that a half day job still occupies most of a day once travel and preparation are counted. That is the figure that makes replacing a single board disproportionately expensive and the reason it pays to bundle work. If there are three marginal boards you have been watching, they belong in the same visit as the one that has clearly failed.

Paying one minimum charge instead of two is the easiest saving available on this kind of work. Single board replacement runs $120 to $320 each, matched, back primed, fitted and primed in, with the spread driven almost entirely by the profile. A standard modern profile off the rack sits at the bottom of that range, and a nineteenth century profile needing custom milling sits well above it until the setup cost is spread across enough boards. Splicing a section into an existing board costs $95 to $240 where the damage is localised and the cuts can land on studs. Access above ground floor height adds to both figures, sometimes substantially where scaffold is required in place of trestles. Custom profile milling carries a setup fee of $380 to $1,400 charged once for the order, plus a higher rate per metre for the board itself than a stock profile.

On a heritage house this is the one number that changes how you should think about the job. Replacing four boards on a milled profile may cost little more than replacing two, and running spare lengths for future repairs while the cutter is set up adds only the timber cost. Many owners order an extra three or four metres for exactly that reason, and store it flat and under cover against the next repair. Larger repairs have their own rates. Replacing the bottom course along one elevation commonly runs $1,400 to $4,800 depending on length, profile and access, and it is a frequent job on older Victorian houses where ground clearance has been lost.

Framing repairs found behind the boards run $65 to $180 a lineal metre for bottom plate and stud work. A vapour permeable membrane, where enough wall is open to install it, adds $9 to $22 a square metre and is worth taking up on anything larger than a few boards. Finishing is quoted separately often enough that it is worth confirming. Spot priming and painting a repaired area runs $40 to $95 a square metre, and painting out to a natural break instead of blending mid wall is usually part of the job and not an extra.

On a pre-1970s house, lead safe preparation adds 15 to 35 percent to the preparation component. Where the whole elevation is going to need repainting anyway, doing the boards and the paint in one campaign is considerably cheaper than two visits. Access and setup are then paid for once instead of twice. Regional pricing follows a familiar pattern. Carpenters travelling from Melbourne into Gippsland, the Wimmera, the northeast or the Mallee add travel and sometimes accommodation, which weighs heavily on a small job where the work itself is only a day. Local trades in Ballarat, Bendigo, Geelong, Shepparton and Traralgon often price better on small work but carry longer waiting lists.

Milling for a heritage profile may also need to be done in a metropolitan mill and freighted, which adds both cost and a week or two. Asking each quote to state how travel, milling and delivery have been allowed for makes regional comparisons far clearer. Keeping on top of a weatherboard wall is mostly a matter of two habits. The first is a slow walk around the house each spring, looking at the bottom course, the cut ends beside windows and doors, the paint around fixings and anywhere the ground has crept up against the timber.

The second is clearing the gutters before winter so water goes where it was meant to. Where the paint is chalky, cracked or flaking instead of simply dirty, the repaint is overdue and every board on the wall is losing protection, which is the point at which small problems start multiplying. The exterior painting page covers what a full repaint involves. Timing the repaint to follow the board work, rather than the reverse, saves setting up twice.

What to Look Out For

Be wary of a carpenter who is not interested in why the board rotted. On a wall that has failed, the water entry point is the actual job and the damaged timber is the consequence, so a quote that goes straight to replacement without a word about the cause has priced half the work. Find out what they think let the water in and what they propose to do about it. An answer that involves the gutter, the flashing or the ground level is a good sign.

Watch for boards fitted without back priming or with cut ends left bare. This is the most commonly skipped step on Victorian weatherboard work and it is completely invisible once the paint is on, which is exactly why it gets skipped. Check whether there will be a primer tin at the cutting station. Those few minutes per board decide whether the repair is still sound in fifteen years or failing in five. Be careful about profile matching on a period house.

If a carpenter tells you the modern equivalent is near enough, what they are describing is a wall whose shadow line alters partway along the elevation, and that alteration is plain from the street. On anything more than one or two boards, custom milling is usually the cheaper answer once the setup is spread across the order. On an unusual profile, have one length run as a sample before committing to the order. Check the fixings and the nailing line. Hot dip galvanised or stainless steel depending on how close you are to salt air, a single fixing line on lapped boards so each board can move, pre-drilling in hardwoods and sensible edge distances are all things a specialist does automatically. Nails driven through both the new board and the one below will split the wall within a summer, and ordinary steel fixings will streak rust down a freshly painted elevation within two winters.

Finally, be cautious of anyone dismissing the age of the house when lead paint or asbestos comes up. Both are entirely manageable with ordinary controls that add little to a small job, and both are serious if ignored. A contractor who treats those questions as an obstacle to getting started has told you something useful about the standard of the rest of their work. It is the easiest test to apply during a quote and the most revealing. It costs you nothing to ask and it separates the trades who work on period housing regularly from those who do not.

How to Get Comparable Quotes

Do the chalk exercise before anyone visits. Walk each elevation, press and tap the boards, mark every soft or suspect area including the marginal ones, and count them. Note the build date if you know it, any leaks or damp patches inside, whether the gutters overflow and whether soil or paving touches the bottom course. Handing every carpenter the same marked up wall and the same information means three quotes for the same job instead of three different interpretations of it. Then ask each of them the same questions. What they think caused the damage, whether the profile is stock or needs milling and what the setup costs, the price for the boards you have marked and the price for a larger number, whether back priming and cut end sealing are included, what fixings they use, what happens if framing damage is found and at what rate, whether painting is included and how far the paint will carry, how they will handle lead paint on older coatings, and what warranty applies.

Those answers are what make the prices comparable. Asking everyone the same questions in the same words is worth the ten minutes it takes to write the list down. Always ask for the price at two quantities. The cost of replacing the four boards that have failed and the cost of replacing the whole bottom course are often much closer than owners expect, because the visit, the setup and the milling are charged once either way.

Where the difference is small, doing the larger scope now avoids a second call out within a few years. That single question saves more money on this kind of job than any amount of negotiating on the rate. Keep the record afterwards and keep the offcut. Note the species, the profile with its measurements or milling drawing, the supplier and mill, the fixing type, the paint system and colour codes, and the photographs taken with the boards off. A short length of the milled profile stored in the shed makes the next repair straightforward years later, and the milling drawing on file means the cutter can be reproduced without another measuring exercise. With that small file to hand, every later quote on the house is quicker to get and easier to trust.

A weatherboard wall is among the most forgiving cladding systems ever built, because anything that fails can be taken out and replaced without touching the rest of the house. What determines whether that stays true is finding the water, matching the board, sealing every cut and keeping the paint film sound. Those four habits are what have carried Victorian weatherboard cottages through a century and a half, and none of them is expensive when it is done at the right time. Left late, every one of them becomes a much larger bill, which is the only real argument this page is making.
