Repointing Cost UK: Price per m², Whole House and Chimney

Mortar is the quiet part of a brick wall. Nobody admires it when a house looks good, but when it starts to fail, the wall lets water in, the bricks suffer, and a small maintenance job turns into a much larger repair. Repointing, cutting out the old, weathered mortar and replacing it with fresh mortar, is one of the most common brickwork jobs on a UK house, and one of the most confusing to price, because quotes can vary by thousands of pounds for what looks like the same work.

The variation is not usually a mystery once you know what drives it. The mortar type matters, cement or lime, and the difference is not just price. The area matters, but so does how much of that area genuinely needs repointing. Access matters, because scaffolding can cost almost as much as the pointing itself on a tall elevation. And the condition of the wall matters, because raking out hard, failed mortar takes far longer than raking out soft, crumbling joints.

This guide works through UK repointing costs in that order: price per square metre, price by job size, how to tell whether your mortar is actually failing, why lime matters so much on period homes, the extras that catch people out, and where the line sits for DIY patch repointing. All prices are typical ranges from UK cost guides checked in October 2026, given so you can sense-check a quote. They are not a price for your house, and London prices typically run 10 to 20 percent higher than the national ranges below.

Repointing Cost per m²: Cement vs Lime

The headline figure most guides start with is the cost per square metre, and for standard brickwork it is fairly consistent across sources. Checkatrade, updated June 2026, puts repointing a brick wall at £50 to £60 per square metre including labour and clean-up, with an average of £55 per square metre. Other 2026 guides give a wider range for standard cement mortar, £25 to £60 per square metre, with the lower end applying to straightforward, easily accessed walls in good condition and the higher end to walls that need more preparation.

Stone walls cost more. Checkatrade puts stone wall repointing at £60 to £100 per square metre, averaging £80, because stone joints are irregular, the work is slower, and raking out often reveals deeper recesses that need extra mortar. If your house is stone rather than brick, do not budget on brick rates.

Lime mortar is the other main price step. Bark’s 2026 guide puts lime mortar repointing at £60 to £90 per square metre, and a 2026 roofing guide gives a similar £60 to £100 per square metre for lime work on London Victorian properties. Lime costs more because it is slower to apply, it needs more skill, and it cures more slowly than cement. It is not a premium finish for its own sake. On the houses that need it, it is the correct material, and the reasons are covered in the period homes section below.

There is also a specialist tier above ordinary lime work that should not be confused with it. Heritage and listed-building lime pointing, using natural hydraulic lime and conservation techniques, is published by specialist contractors at £245 to £360 per square metre including labour and scaffolded access in some cases. That is not a rate to apply to an ordinary Victorian terrace. If your house is listed, or in a conservation area with a specific mortar requirement, get a quote from a conservation-accredited specialist rather than budgeting from a generic guide.

A per-square-metre price is only useful if you know how many square metres are actually being repointed. A terraced front elevation is typically 30 to 40 square metres of wall, which is a useful check: a quote for a front elevation at £55 per square metre should land somewhere near £1,650 to £2,200 before scaffolding, and a quote far above that should come with a clear explanation of what extra work is included. Ask any contractor to state the measured area, the mortar type, and whether raking out and scaffolding are included, because a low per-metre rate that excludes both is not comparable with a higher rate that includes them.

Repointing Cost by Job: Wall, Elevation, Whole House and Chimney

Most homeowners do not buy repointing by the square metre. They buy a job: one wall, one elevation, a whole house, or a chimney. The whole-job figures below come from the same 2026 guides, and they show why the per-metre rate alone does not tell the story.

A single wall, front or side of a house, is typically put at £1,500 to £2,200 by Checkatrade, and a 2026 roofing guide puts a terraced house front at £1,500 to £2,500 excluding scaffolding. That is the most common repointing job, because the front elevation usually weathers first, facing the prevailing weather, and it is the elevation a buyer or surveyor sees first.

A full Victorian terraced house is typically put at £3,000 to £4,400 by Checkatrade, and £2,500 to £4,000 by another 2026 guide for cement mortar work. The range widens once lime is involved: the same full terrace in lime, with scaffolding and raking out included, is put at £4,000 to £9,000 and above by one 2026 London-focused guide. The lesson is not that one guide is wrong. It is that “full house” means different things: cement or lime, one elevation or all of them, scaffolding included or added on top.

A semi-detached house is typically put at £4,000 to £5,000 by Checkatrade, and at £3,500 to £5,500 by another guide. A detached house is typically put at £4,000 to £8,000 or more, depending on wall area. Detached houses vary so much in size and wall area that a whole-house figure without a measured area is little more than a guess, and a contractor who quotes a detached house without measuring the elevations has not done the work needed to price it properly.

Chimney repointing is a job of its own, and it often needs doing before the main walls do. Chimneys are exposed to wind and rain from all directions, with no shelter from a roof overhang, so their mortar deteriorates faster than sheltered wall mortar. Checkatrade puts chimney repointing at £500 to £1,000 per chimney, and MyBuilder and a 2026 roofing guide both put it at £500 to £1,200 for the pointing work, excluding scaffolding. Once scaffolding for chimney access is added, typically £500 to £1,000, a total chimney job commonly lands at £1,000 to £2,200. Chimney repointing is also commonly combined with lead flashing repair, since both jobs need the same scaffolding, and doing them separately means paying for access twice.

If you are only repointing because a survey flagged it, ask what the survey actually flagged. A survey report that says “repointing required” may mean one elevation, or it may mean localised patching. The difference between patching the failed areas and repointing every elevation can be several thousand pounds, and the right scope is the one that matches the condition of the wall, not the broadest quote.

Signs Your Mortar Is Failing

Repointing is needed when the mortar, not just the appearance of the wall, has failed. Mortar is meant to be sacrificial: it is softer than the brick, so it weathers first and protects the brick face. When it has weathered too far, it stops doing that job, and water gets a route into the wall.

The clearest sign is mortar that crumbles when you press it, or that falls out of the joint in pieces. Run a finger, or the end of a key, along a joint on a sheltered part of the wall and then on the weather-facing elevation. Sound mortar feels hard and resists scratching. Failed mortar feels soft, sandy and powdery, and it leaves grit on your finger. Deep recesses, where the mortar has eroded back from the face of the brick, are another sign, especially if the recess is more than a few millimetres deep and widespread rather than confined to one patch.

Cracked and open joints are the next sign, particularly horizontal cracks along a bed joint, or joints that have opened up around windows, doors and lintels where movement concentrates. Hairline cracks in a small number of joints are not, on their own, a reason to repoint a whole elevation. Widespread cracking, especially combined with crumbling, is.

Water signs are the ones that matter most, because they show the failure is already affecting the house. Damp patches inside that line up with an external wall, especially patches that get worse after rain, can point to failed pointing letting water through, although damp has other causes too, and our guide to types of damp in a house works through how to separate penetrating damp through failed mortar from condensation and rising damp before you commit to any treatment. Outside, look for bricks whose faces are flaking or spalling, where the outer surface of the brick is peeling away. Spalling often means water is getting into the brick and freezing, or that a hard cement mortar is trapping moisture against a soft brick, and it is a sign to get advice promptly rather than simply repointing over the problem.

Vegetation in joints is a smaller but telling sign. Moss and small plants rooting in mortar joints mean the joints are holding moisture and have opened enough for roots to take hold. A few patches of moss on a north-facing wall are normal. Plants growing out of the pointing across an elevation mean the mortar has been open for a long time.

What does not, on its own, mean you need repointing? Discoloured mortar, minor surface weathering, and a small number of eroded joints on an otherwise sound wall. Mortar weathers. A wall that is 40 years old will not look like a new wall, and that is not a defect. The question is always how much of the wall has genuinely failed, and whether water is getting in, not whether the pointing looks new.

Why Lime Matters on Period Homes

If your house was built before 1919, or has solid brick or stone walls rather than a cavity, the mortar type is not a cosmetic choice. It is a building physics choice, and getting it wrong can damage the wall it was meant to protect.

The rule is simple: the mortar should be softer than the brick. Victorian and Edwardian bricks are generally soft, fired at lower temperatures than modern bricks, and the lime mortar they were built with is softer still. That softness is deliberate. When the wall moves slightly, when it gets wet and dries out, and when frost acts on it, the mortar gives way first. It can be raked out and replaced. The brick survives.

Cement mortar reverses that relationship. Modern cement mortar is hard, dense and much less permeable than lime. On a soft brick, it does not give way. The brick does. Water that would have evaporated through lime mortar gets trapped behind a cement joint, and in winter it freezes inside the brick face, causing spalling. The wall looks worse after cement pointing than it did before, and the damage to the brick is permanent in a way that failed mortar is not.

Lime mortar also breathes. A solid wall was designed to absorb moisture and release it, through lime mortar, lime plaster and, often, limewash or breathable paint. Covering that system with cement pointing, cement render and modern waterproof coatings traps moisture inside the wall. That trapped moisture shows up as damp inside, and it is one of the reasons damp problems in period houses are so often misdiagnosed: the damp is not rising from the ground, it is trapped in a wall that can no longer breathe, and the treatment offered, more cement and waterproofing, makes it worse.

That is why lime work costs more and takes longer. Lime mortar cures by carbonation, absorbing carbon dioxide from the air over weeks rather than setting chemically in days like cement. It needs protection from frost and heavy rain while it cures, it needs the right mix for the job, from a soft lime putty mortar for a sheltered internal wall to a natural hydraulic lime for an exposed chimney, and it needs a tradesperson who understands those differences. A contractor who quotes lime work at cement prices, or who plans to use the same mix on a chimney and a sheltered garden wall, has not understood the material.

For listed buildings, the mortar type may not be a choice at all. Listed building consent can require a like-for-like lime mortar, and a conservation officer may specify the mix. If your house is listed, check before any work starts, and budget for specialist work rather than a generic rate. Even for unlisted period houses, a sympathetic mortar match matters for appearance and for resale: a front elevation repointed in hard grey cement, with joints wider and flatter than the original, is visible from the street, and a buyer with a surveyor will notice it.

None of this means cement mortar is bad. On a house built after the 1930s, with hard modern bricks and a cavity wall, cement mortar is the normal, correct material, and it is cheaper and faster for good reason. The mistake is applying the modern material to the old wall, or the old material at modern prices to the new wall. Match the mortar to the house.

Scaffold and Raking-Out Extras

Two extras account for most of the surprise in a repointing quote: scaffolding and raking out. Both are legitimate costs, but both are also places where a headline per-metre rate can hide a large part of the real bill.

Scaffolding is needed for anything above comfortable ladder height, and for a full elevation it is not optional in any safe sense. A 2026 roofing guide puts scaffolding hire at £500 to £1,500 for a typical terraced house, and Checkatrade puts scaffolding at £15 to £25 per square metre. For a chimney, scaffolding is typically £500 to £1,000 on its own, and Checkatrade’s chimney flashing guide puts high-level chimney scaffolding at £500 to £820 per week. The cost rises with height, with awkward access, such as a narrow side passage or a conservatory roof that cannot be loaded, and with hire duration, since lime work cures more slowly and may need the scaffold up longer than cement work.

Ask whether scaffolding is included in the quote, how long the hire covers, and what happens if the job overruns. A quote that excludes scaffolding entirely will look cheaper than a quote that includes it, and comparing the two without adjusting for access is meaningless. If two jobs need scaffolding at the same time, such as chimney repointing and gutter work, combining them saves a second scaffold hire, and our guide to gutter replacement cost covers the scaffold factors on that side of the job. The same logic applies to roof work: if scaffolding is already up for repointing, it is the cheapest time to have the roofline checked, and our guide on how to tell if your roof needs repair or replacement lists the signs worth checking while access is already paid for.

Raking out is the labour of cutting or grinding out the old mortar before new mortar goes in, and it is where the condition of the wall shows up in the price. Checkatrade puts raking out at £20 to £50 per square metre as a separate line item, and other guides give a similar range. The depth matters: sound practice is to rake out to a depth of at least twice the width of the joint, and often 15 to 25mm, so the new mortar has enough depth to bond. Shallow raking out, sometimes called a “scratch and dab” or a surface repoint, looks tidy for a year and then fails, because a thin skin of new mortar has nothing to key into.

Raking out also carries a risk that a good contractor will warn you about. If the old mortar is still sound, raking it out can damage the brick, especially soft period bricks and the arrises, the sharp edges, of the brick face. A contractor who insists on raking out every joint on a wall where most joints are sound is either pricing work that is not needed, or does not understand the material. The right specification is usually to rake out and repoint the failed joints, and leave sound joints alone, even if that means the finished wall is not uniformly new-looking. A wall that is partly repointed and structurally sound is a better result than a wall that is uniformly repointed and damaged in the process.

Other extras to check on a quote are brick replacement, where spalled or cracked bricks need cutting out and replacing with matching bricks, which can cost significantly more per brick than the pointing around it; lintel and window surround repairs, where failed pointing has let water into the structure around an opening; and waste removal and clean-up, which Checkatrade includes in its per-metre rates but some contractors charge separately. None of these are reasons to reject a quote. They are reasons to ask for an itemised quote, so you can see what is included and compare like with like.

DIY Patch Repointing: Where the Line Is

Patch repointing a small, low-level area is one of the more realistic DIY brickwork jobs, but only within clear limits. The line is set by height, by area, by mortar type, and by what the wall is telling you.

A low-level patch, at ground level, on a garden wall or the bottom courses of a house wall, using a matching mortar, is a sensible DIY job if you are comfortable with basic tools and you follow the preparation properly. The work is straightforward in principle: rake out the failed mortar to a proper depth, brush out dust, dampen the joint, press new mortar in firmly in layers rather than smearing it on the surface, and finish the joint to match the existing profile, whether that is flush, bucket-handle or weather-struck. The materials are cheap, a bag of mortar, a pointing trowel and a jointing tool, and a small patch can be done in an afternoon. Done well, it keeps water out and it buys years.

The line is crossed in several places. Anything above ladder height, and anything that needs scaffolding, is not a DIY job, because working at height with a grinder and loose mortar is a safety risk that no saving justifies. A whole elevation is not a DIY job either, because consistency of mix, joint profile and curing matters across a large area, and a patchy, inconsistent elevation is worse than a professionally repointed one, both visually and for water resistance. Lime work on a period house is a judgement call: a small lime patch with a ready-mixed lime mortar, following the supplier’s guidance on curing and frost protection, is within reach of a careful DIYer, but a full lime repoint, or any lime work on a listed building, needs a specialist.

The line is also crossed when the wall is telling you something bigger is wrong. If bricks are spalling across an elevation, if the wall is bowing or cracking structurally, if damp inside is widespread rather than localised, or if a chimney stack is leaning or shedding bricks, repointing, DIY or professional, is not the fix on its own. Those signs need a structural or surveyor’s assessment first, because pointing over a structural problem hides it while it gets worse.

A practical rule is this: DIY the patch you can reach safely from the ground, on a wall whose bricks are sound, with a mortar that matches the existing mortar, and where the failed area is small and localised. Hire a professional for anything at height, anything covering a full elevation or a whole house, any chimney work, any lime work beyond a small patch, and any wall where the bricks themselves are failing. The saving on a small patch is real. The saving on a large job done badly is not a saving at all, because it will need doing again, and the bricks may be worse by then.

Frequently Asked Questions

How much does repointing cost per m² in the UK?

Typically £25 to £60 per square metre for cement mortar on brickwork, with Checkatrade averaging £55 per square metre, and £60 to £90 per square metre for lime mortar on period properties. Stone walls typically cost £60 to £100 per square metre. Raking out is often extra, typically £20 to £50 per square metre, and scaffolding is often extra too.

How much does it cost to repoint a whole house?

A Victorian terraced house is typically £3,000 to £4,400 in cement, a semi-detached house £4,000 to £5,000, and a detached house £4,000 to £8,000 or more, depending on wall area. A full terrace in lime, with scaffolding and raking out included, can reach £4,000 to £9,000 and above. Always get an itemised quote with the measured area, mortar type, scaffolding and raking out stated separately.

How much does chimney repointing cost?

Typically £500 to £1,200 for the pointing work, excluding scaffolding. Scaffolding for chimney access typically adds £500 to £1,000, taking a total chimney job to roughly £1,000 to £2,200. Combining chimney repointing with flashing repair while scaffolding is up saves a second access cost.

How do I know if my house needs repointing?

Look for mortar that crumbles or falls out, deep recesses in the joints, widespread cracking, water getting in after rain, spalling brick faces, and plants rooting in the joints. A small number of weathered joints, or discoloured mortar on an otherwise sound wall, does not mean a whole elevation needs repointing.

Should I use lime or cement mortar?

Match the mortar to the house. Houses built after the 1930s with hard modern bricks normally use cement mortar. Pre-1919 houses with soft bricks and solid walls need lime mortar, because cement is harder than the brick and traps moisture, causing spalling and damp. Listed buildings may require lime by consent, so check before work starts.

Is repointing a DIY job?

A small, low-level patch with matching mortar is a realistic DIY job. Anything at height, a full elevation, a whole house, chimney work, or lime work beyond a small patch should be done by a professional. If bricks are spalling, the wall is cracking structurally, or damp is widespread, get a surveyor’s assessment before repointing at all.

How long does repointing last?

Good repointing on a sheltered wall can last 30 to 50 years or more, and chimney pointing, being more exposed, is often needed every 30 to 50 years even when wall pointing remains sound. Lifespan depends on mortar type, exposure, workmanship and whether the joints were raked out to a proper depth. A thin surface repoint will fail much sooner.
