Short answer
Chimney repointing costs in the UK typically run from around £500 to £1,500 for a full stack, with scaffolding and safe access — not the brickwork itself — usually the single biggest cost. At CPAGM in Chester, a small repointing repair starts from £250, a leadwork patch repair from £195 and a chimney cowl fitting from £150. Every chimney is priced after a few photos or a quick visit, never fixed over the phone, because height and access change everything.
Why chimney repointing prices vary so much
A chimney is the most exposed brickwork on the whole house — it sits up in the wind and rain with no shelter, so the mortar joints weather faster than anywhere else. Repointing means raking out the old, soft, crumbling mortar and re-filling the joints with fresh, correctly mixed mortar. The price is driven far more by getting safely up to the stack than by the pointing itself: a stack you can reach off a roof ladder is one job, the same stack on a tall three-storey Hoole townhouse needing a scaffold tower is quite another.
Around Chester, Cheshire, the Wirral and over towards Wrexham and Flintshire you see a real mix of chimneys. The Victorian and Edwardian terraces in Hoole, Handbridge and Boughton often have tall, slender stacks with original lime mortar that has quietly washed out over a century. Post-war semis and 1960s–80s estates in places like Upton and Saughall tend to have squatter brick or rendered stacks. Each weathers differently, which is exactly why a phone quote is guesswork and a couple of photos tell us most of what we need.
Our weather coming in off the Irish Sea is the other half of the story. Driving rain and repeated freeze-thaw winters get into open joints, expand, and pop the face off the bricks — that is the spalling and flaking you see on a lot of older Chester stacks. Repointing in good time keeps water out and protects the bricks. Leave it too long and you are no longer repointing a stack, you are rebuilding one, which is a much bigger spend.
Raking out vs re-pointing — what you're actually paying for
Repointing is really two jobs, and it helps to know which one you're paying for. 'Raking out' is the preparation: cutting and scraping the old, perished mortar out of every joint back to sound material, usually to a depth of around 15–20mm. 'Re-pointing' is the finishing: pressing fresh, correctly mixed mortar into those raked-out joints and tooling it to shed water cleanly. The raking out is the slow, careful part — and skipping it is the single most common corner that cheap jobs cut.
You'll sometimes be offered a quick 'smear over the top' that skips the raking out entirely. It looks tidy for a season, then the new mortar lets go from the crumbling material behind it and you're back to square one, often with trapped damp making things worse. On older Chester and Cheshire stacks built with soft lime mortar, the mix matters too: a modern, too-hard cement mortar traps moisture and can shatter the historic brick faces in a hard frost, so the mortar is matched to the building rather than mixed to a one-size recipe.
Chimney repair prices at CPAGM
| Job | Guide price | What affects it |
|---|---|---|
| Small repointing repair | From £250 | Raking out and re-pointing a localised area of perished joints on an accessible stack |
| Leadwork patch repair | From £195 | Renewing or patching failed lead flashing where the stack meets the roof, to keep water out |
| Chimney cowl fitting | From £150 | Supply and fit a cowl or bird/rain guard — often done while access is already set up |
These are our real starting prices for smaller, accessible chimney jobs. Larger full-stack repointing and anything needing a full scaffold is quoted individually — we confirm every chimney price after you send a few photos or we take a quick look, because height, access, stack size and the state of the brickwork all change the scope. We never quote a fixed price for a stack we haven't seen.
Full chimney stack repointing — typical UK guide prices
| Job | Guide price | What affects it |
|---|---|---|
| Repoint a full chimney stack | £500–£1,500 | The usual UK range — small accessible stacks at the lower end, tall or multi-flue stacks at the top |
| Scaffolding / access tower | £300–£900+ | Often the single biggest line on the quote; a full scaffold to a two- or three-storey stack costs more than the pointing |
| Re-bed the pots (flaunching) | £150–£400 | Renewing the sloped mortar bed the chimney pots sit in — frequently done at the same visit |
| Rebuild a chimney stack | £1,000–£3,000+ | When the stack is past repointing — a brick-by-brick rebuild, quoted separately |
These are typical UK guide ranges for budgeting only — not CPAGM quotes. Actual cost depends mostly on scaffolding and access, stack size, the number of flues, and whether the brickwork can be saved or needs rebuilding. Send a few photos for a firm figure on your own stack.
Scaffolding and access — the real cost driver
For most chimneys, the mortar and the labour are a modest part of the bill — it's getting safely up to the stack and back down again that moves the number. A low stack on a bungalow or on the back of a single-storey extension might be reached from a roof ladder and cost very little to access. The same repointing on a tall Victorian terrace in Hoole, or a three-storey townhouse in Handbridge, needs a proper scaffold or an access tower, and that alone can be £300 to £900 or more before a single joint is touched.
That's why a genuine chimney quote is never a flat rate. Two identical stacks can differ by hundreds of pounds purely on how they're reached — where the scaffold can stand, whether it's a front elevation over a public path, how many storeys there are, and whether the roof pitch allows a tower. It's also why bundling makes sense: if the scaffold is going up anyway, it's the sensible moment to sort the flaunching, refit a cowl or renew tired lead flashing, because you only pay for the access once.
What chimney repointing actually involves
- 1
Inspect the stack and plan safe access
We check the whole stack — joints, bricks, flaunching, pots, flashing and cowls — and work out how to reach it safely, whether that's a roof ladder, a tower or a scaffold. The access plan is what shapes the price more than anything else.
- 2
Rake out the old mortar
The perished, soft mortar is cut and raked out of the joints to a proper depth. Just smearing new mortar over old, crumbling joints looks fine for a year and then fails — it has to be raked back to sound material first.
- 3
Repoint with the right mortar mix
Joints are re-filled and tooled with a correctly mixed mortar suited to the brick. On older lime-built Chester stacks the wrong, too-hard cement mix can do more harm than good, so the mix is matched to the building.
- 4
Sort the flaunching, leadwork and finish
Where the flaunching is cracked we renew the mortar bed the pots sit in, patch or renew failed lead flashing at the base, refit or replace cowls if needed, and leave the stack weather-tight. You get before-and-after photos and an honest note on the brickwork and flashing.
A chimney stack is no place for a DIY ladder
Chimney work is right at the top of the house, on or above the roofline, often two or three storeys up — and falls from height are the single biggest cause of fatal and serious injury in UK home maintenance. Working off a leaning ladder at roof level, on brittle tiles, near an unstable stack, is genuinely dangerous. If a stack is leaning, badly cracked or shedding bricks, keep people away from below it and get it assessed — leave the access and the repair to someone working safely with the right equipment and full insurance.
Repoint vs rebuild — which does your chimney need?
| Repoint the stack | Rebuild the stack | |
|---|---|---|
| Typical trigger | Mortar joints washed out or soft, bricks still sound | Bricks spalling badly, stack leaning, frost-shattered or moving |
| Guide cost (UK) | Around £500–£1,500 for most full stacks, scaffold included | Typically £1,000–£3,000+ — a larger masonry job, quoted separately |
| How long it lasts | Decades if the bricks underneath are good | A new stack, built to last from scratch |
| Honest advice | If repointing is the right call, that's what we do | If the stack is past saving, we'll tell you straight rather than point over a failing structure |
| Access / disruption | Usually a tower or short scaffold and one short job | Full scaffold, longer on site, bigger spend |
When a chimney needs rebuilding, not repointing
Repointing only works if the bricks themselves are still sound — it renews the mortar between them, not the bricks. Once the brick faces are badly spalling and flaking, the stack is leaning out of true, or the masonry has been shattered by years of frost, there's nothing solid left for fresh mortar to hold onto, and the honest answer is a rebuild rather than a patch. A stack that's visibly leaning, dropping bits of brick into the gutter, or cracked right through is a safety issue as much as a cost one, and worth getting looked at promptly.
A rebuild means taking the stack down to a sound level and rebuilding it brick by brick, usually reusing the pots where they're good and renewing the flaunching and lead flashing as the work goes up. It's a bigger, fully scaffolded job — typically £1,000 to £3,000 or more as a UK guide — but on a failing stack it's money better spent than repointing over a structure that's on its way out. We'll always tell you straight which one your chimney actually needs; if repointing will do the job, that's what we'll quote.
Photos that get you an accurate price fast
- A wide shot of the whole chimney stack from the ground, so we can see the height, the storeys and how the house is accessed
- A close-up (zoom in) of the mortar joints, the brick faces and the flaunching around the pots, showing the gaps, cracks or flaking
- A photo of the lead flashing where the stack meets the roof, and any damp patch or staining on a chimney-breast wall or ceiling inside — which can point to failed pointing, flaunching or flashing
Frequently asked questions
How much does chimney repointing cost?
As a UK guide, chimney repointing costs around £500 to £1,500 for a full stack, with scaffolding and access usually the biggest single factor. At CPAGM, smaller localised repointing repairs start from £250 on an accessible stack. The exact price depends on height, access and stack size, so we confirm it after a few photos or a quick visit.
How much does it cost to repoint a chimney?
The cost to repoint a chimney in the UK typically runs from about £500 for a small, accessible stack up to £1,500 for a tall or multi-flue stack that needs a full scaffold. Much of that is the access rather than the pointing itself. CPAGM's smaller repointing repairs start from £250, confirmed after you send a few photos.
What are typical chimney repointing prices in the UK?
Chimney repointing prices in the UK generally sit between £500 and £1,500 for a full stack, plus scaffolding where it's needed. Re-bedding the pots (flaunching) adds roughly £150 to £400, and a full rebuild — when the stack is past saving — is typically £1,000 to £3,000 or more.
How much to repoint a chimney stack?
Chimney stack repointing usually costs £500 to £1,500 in the UK, depending mainly on how tall the stack is and how it's reached. A low stack off a roof ladder is at the bottom of that range; a three-storey stack needing a full scaffold is at the top. We price every stack after seeing photos rather than over the phone.
What does chimney repair cost?
Chimney repair costs vary widely because the work is at the very top of the house. A cowl fitting from £150 or a leadwork patch repair from £195 is modest, but a full repoint (£500–£1,500 as a UK guide) or a rebuild (£1,000–£3,000+) is pushed up by scaffolding, height and stack condition. The repair itself is often the cheaper half of the job — the access is the rest.
What's the difference between raking out and re-pointing?
Raking out is cutting and scraping the old, perished mortar out of the joints back to sound brick, usually around 15–20mm deep. Re-pointing is filling those raked-out joints with fresh, correctly mixed mortar and tooling it to shed water. Raking out is the slow, essential prep — a job that skips it and just smears mortar over the top will usually fail within a season or two.
Do you need scaffolding to repoint a chimney?
Often yes for a safe, proper job on a two-storey-or-taller stack — either a scaffold or an access tower. Scaffolding is frequently the single biggest cost on a chimney quote, sometimes £300 to £900 or more. Some lower stacks can be reached more simply. We'll tell you what access the job needs before quoting, so there are no surprises.
When does a chimney need rebuilding instead of repointing?
Repointing only renews the mortar, so it works while the bricks are still sound. Once the brick faces are badly spalling, the stack is leaning, or the masonry is frost-shattered and moving, there's nothing solid for new mortar to grip and a rebuild is the honest call. A leaning stack or bricks dropping into the gutter should be checked promptly on safety grounds.
How do I know if my chimney needs repointing?
Look for gaps, crumbling or missing mortar between the bricks, sand collecting at the base of the stack or in the gutter, flaking brick faces, cracked flaunching around the pots, or damp on the chimney breast inside. Any of those is worth getting checked before it turns into a bigger, more expensive repair.
Can I repoint my own chimney?
We'd strongly advise against it. Chimney work is at roof level, often two or three storeys up, and falls from height are the biggest cause of serious injury in UK home maintenance. Safe access, the right mortar mix and sound pointing all need the proper equipment, experience and insurance — it isn't a ladder-and-a-bag-of-mortar DIY job.
Do you cover Cheshire and the Wirral as well as Chester?
Yes. CPAGM covers Chester and roughly a 45-minute radius, including the wider Cheshire area — Hoole, Handbridge, Upton, Saughall, Frodsham, Northwich and Tarporley — the Wirral and Ellesmere Port, and parts of Wrexham and Flintshire.
