Repointing a standard brick wall in cement mortar typically costs £45–£90 per m² in 2026, materials and labour included. If the wall needs lime mortar instead — and most solid brick or stone built before roughly 1919 genuinely does — that rises to roughly £60–£125 per m². Scaffold or tower access, where the job needs it, is usually the single biggest thing added on top, and chimney repointing on its own typically runs £400–£1,500 once access is factored in.
But the figure worth getting right first isn’t the price, it’s the mix. A cement mortar repoint on a wall originally built with lime is one of the more common ways I see well-intentioned maintenance cause more damage than it prevents — trapping moisture that’s meant to evaporate out through the joints, and pushing it into the brick face instead. And before either mortar goes anywhere near the wall, it’s worth asking whether the pointing has actually failed, or whether it just looks tired from the pavement, which is a different question with a much cheaper answer.
I diagnose masonry condition for a living. I don’t repoint it, so I’ve no reason to talk you into a job you don’t need. What follows is 2026 pricing across cement and lime, what actually drives the cost per metre, and why the mortar specified matters rather more than most quotes let on.
The short answer
Figures below were checked on 2 August 2026 against BookaBuilderUK, Greens Brickwork & Building and MyJobQuote’s 2026 cost guides, cross-referenced against each other rather than taken from one source alone. As with most trades in this series, Kent, Sussex, Surrey and London trend meaningfully above the national figures quoted here — by roughly 20–35% on more than one specialist’s own regional breakdown.
| Job | Typical cost (2026) | What’s included |
|---|---|---|
| Cement mortar repointing | £45–£90/m² | Standard 20th-century solid or cavity brick |
| Lime mortar repointing | £60–£125/m² | Needed on most pre-1919 solid-wall brick & stone |
| Scaffold or tower access | £600–£1,800 per elevation; £2,500–£6,000 full wrap | Often the single biggest swing on the final bill |
| Chimney repointing | £400–£1,500 | Usually needs its own access even on a ground-floor job |
So as a rough guide: a 3-bed semi with somewhere around 90–100m² of external wall, repointed in cement with a run of scaffold, lands around £4,000–£9,000 all in. The same house, if it’s genuinely pre-1919 solid-wall brick needing lime, is more realistically £5,500–£12,500. Neither number is precise — wall area, joint condition and access swing it a long way — but it’s the sum worth doing yourself before comparing two quotes that may be pricing two different jobs.
What drives the price
Wall area, not house size. You’re paying per square metre of wall actually repointed, not per bedroom. A small terrace needing its whole front elevation done can cost more than a larger house that only needs one gable.
How far the old mortar has actually gone. Raking out perished mortar to the right depth — enough for the new pointing to key in properly, not just skimmed over the top — takes longer on a wall that’s genuinely failing than one that’s only lightly weathered. A quote that doesn’t specify a rake-out depth is usually pricing the easier job.
Cement or lime. Lime costs more to buy, takes longer to cure and needs more skill to get the mix and finish right, which is most of why it runs 20–40% above cement per metre. More on why the choice isn’t optional below.
Colour and joint profile. Matching the existing mortar colour and the profile it was finished to — flush, weathered, bucket-handle — takes a trial panel and a bit of trial and error. Get it wrong and it’s visible from the street for as long as the pointing lasts.
Access. Scaffold and tower hire is usually the largest single variable on the whole job, and it’s the line most often left vague in a verbal quote.
Region. Kent, Sussex, Surrey and London trend above the national figures quoted here, in line with most trades in this series.
Worth flagging separately: some quotes come in noticeably below the ranges above because they’re pricing bare labour — one specialist’s own 2026 figures put the raw labour charge at £20–£50/m² — with materials, rake-out, access and clean-up added as extras rather than included. It’s not necessarily a bad quote, but it isn’t comparable to an all-in figure unless you check what it excludes.
Why cement mortar is often the wrong call on older brick
Traditional solid-wall construction, most of what’s standing from before roughly 1919, was built on the assumption that rain gets into the wall and has to get back out again. The mortar joint is the exit route: lime mortar is deliberately softer and more porous than the brick or stone either side of it, so moisture evaporates out through the pointing rather than sitting in the masonry units. Historic England’s own guidance is explicit that unsuitable repointing, cement mortar chief among it, is one of the most frequent causes of damage it sees in older buildings.
Cement mortar reverses that arrangement. It’s harder and less porous than the surrounding brick, so instead of drying through the joints, moisture gets forced to find another way out — usually straight through the face of the brick itself. In a hard winter, water trapped that way can freeze and spall the brick face clean off; over longer periods it carries salts into the masonry that crystallise and weaken it from within. The wall ends up looking freshly repointed while the brick behind it is being quietly wrecked, which is a slower and considerably more expensive problem to put right than the pointing ever was.
The other side of this is that lime mortar is meant to wear out. It’s a deliberately sacrificial layer, softer than the masonry so that it erodes over decades instead of the brick or stone doing so. Pointing that looks tired on an old house isn’t necessarily a defect; it can simply be lime mortar doing exactly the job it was designed for, on schedule.
Do you actually need to repoint at all?
Weathered and failed aren’t the same thing, and the difference is worth establishing before anyone quotes a five-figure job. Signs the pointing has genuinely failed, rather than just aged: mortar you can dig out to real depth with a fingernail or a key rather than just brush dust off; cracking that channels rainwater in behind the brick face instead of over it; plants or moss rooting properly in the joints rather than sitting on the surface; and, internally, damp patches that track the pattern of open joints rather than rising damp’s usual bottom-of-wall tide-mark. A wall that’s merely lost its crisp finish from twenty years of weather, with the mortar still solid a few millimetres in, doesn’t need £5,000–£12,000 spent on it yet.
If the house is listed or sits in a conservation area, there’s a second question worth asking before instructing anyone: some conservation areas carry an Article 4 direction specifically restricting external repointing, and on a listed building, repointing in the wrong mortar or a different joint profile without consent can itself constitute unauthorised works — regardless of how well the job is done. Check with the local conservation officer before agreeing a spec, not after the scaffold comes down.
What I’d watch for in a quote
- The mortar mix specified in writing — the lime type or the cement:sand ratio — not just “repointing” as a single line.
- A trial panel agreed first on anything where colour or profile matching matters, rather than discovering the match once the whole elevation is done.
- Rake-out depth given as a spec, not left as “as required”.
- Access priced separately, so you can see what the scaffold or tower is costing versus the pointing itself.
- No cement mortar proposed for a pre-1919 solid wall without a clear reason why lime isn’t being used.
- An insurance-backed guarantee that survives the contractor going out of business, and no pressure to sign on the day of the quote.
Questions I get asked
How much does repointing cost per m²? In 2026, cement mortar repointing typically costs £45–£90 per m², and lime mortar, needed on most pre-1919 brick and stone, costs roughly £60–£125 per m². Scaffold access adds £600–£1,800 for one elevation, more for a full wrap. A 3-bed semi with 90–100m² of wall lands around £4,000–£9,000 all in for cement, or £5,500–£12,500 for lime.
Do I need lime mortar or cement mortar? It depends how the wall was built, not on preference. Most brick and stone from before roughly 1919 was built to breathe through soft lime joints; cement traps moisture instead, which drives damp, frost-blown brick faces and salt damage rather than preventing them. Standard 20th-century cavity brick is generally fine in cement. If you’re not certain which you have, that’s worth checking before a contractor decides for you by default.
Do I need scaffolding to repoint a house? Generally yes above a single storey, whether full scaffold or a run of towers moved along the wall. Ground-floor sections and garden walls can sometimes be reached from a ladder or hop-up, which is one reason two quotes for “the same job” can differ so much — check what access each one actually includes.
How do I know if my house actually needs repointing? Mortar is a sacrificial layer, meant to wear faster than the brick around it, so a wall that looks tired from the pavement often still has pointing doing its job. Genuine failure looks like mortar you can dig out to real depth with a fingernail or key, cracking that lets water track behind the brick, and vegetation rooted properly in the joints — not just a lost crisp finish.
If a contractor’s quote has you looking at a full repoint and you’re not sure whether the pointing has genuinely failed, or whether cement has already gone in somewhere it shouldn’t have, that’s exactly the kind of thing a building survey picks up before you commission the work. Call 07946 618203 or get in touch and I’ll give you a straight answer before you spend the money.
Small print. This guide is general information, not advice on a specific property, and it doesn’t replace a proper survey and quote for your own home. Prices were researched and correct to the best of my knowledge on 2 August 2026; costs move and vary by region and property. Always get at least three written quotes, specifying the mortar mix, and get an independent view on whether the work is actually needed before it’s commissioned.
