Quick answer: You need a chimney rebuild in Ealing when the stack is leaning, cracked through or has loose, crumbling bricks that repointing can’t save. Often, though, only the top section needs rebuilding. So we take it down to sound brickwork, rebuild with matching bricks, and fit new flashing and flaunching. Most rebuilds take a few days, although scaffolding adds time.

Why does a chimney rebuild in Ealing come up so often?
Builders put up most of Ealing’s streets between the 1880s and the 1930s. Victorian and Edwardian terraces in Ealing, West Ealing and Hanwell, and the 1920s and 1930s semis further out, nearly all have brick chimney stacks, often shared between two houses. So many are now well over 100 years old. Frost, wind-driven rain and decades of hard cement repairs on soft old bricks have taken their toll, especially at the top of the stack.
Repair, partial rebuild or full rebuild?
This is the first question we answer on any chimney survey, because not every tired stack needs a chimney rebuild in Ealing. Here’s how we decide.
| Condition of the stack | Usual fix | Why |
|---|---|---|
| Mortar cracked or washed out, bricks sound | Repointing | The bricks are fine; only the joints need renewing |
| Leak where the stack meets the roof | New lead flashing | The water is getting in at the junction, not through the stack |
| Cracked cement collar around the pots | New flaunching | Rain is running down inside the stack from the top |
| Top few courses loose, pots unstable | Partial rebuild | The top takes the worst weather; below it is sound |
| Stack leaning, cracked right through or badly spalled | Full rebuild above the roofline | The stack can’t be made safe by repairs |
| Chimney no longer used and in poor condition | Removal (with structural advice) | Sometimes taking it down is the better option |
Either way, we’ll always show you photos of what we find, so you can see why we’re recommending a repair or a rebuild.
What’s involved in a chimney rebuild in Ealing?
- Scaffolding goes up around the stack, with roof protection.
- Pots and flaunching come off, and we keep any we can reuse.
- We then take the stack down course by course to sound brickwork.
- We check the flues while the stack is open, so we can deal with any damage inside now rather than later.
- Rebuilding with matching bricks (reclaimed where needed) and a mortar matched to the bricks. Soft old bricks especially need a softer, lime-based mix.
- We build in a damp-proof tray or course where the stack design allows.
- New flaunching and pots then go back on, with caps or cowls if needed.
- We fit new lead flashing and soakers where the stack meets the roof.
- Roof tiles or slates around the stack are finally made good.
On working chimneys, the flue also has to stay clear and safe. So if you use an open fire or stove, tell us before work starts.

Do you need permission to rebuild a chimney in Ealing?
Planning permission. Rebuilding a chimney like for like, to the same size, shape and materials, is usually treated as a repair. Still, changing its height or design, or removing it, can need planning permission.
Conservation areas and listed homes. Ealing has 30 conservation areas, including Brentham Garden Estate and Ealing Common (Ealing Council). Chimneys often matter to the character of these streets, so the council may want them kept and rebuilt to match. Listed buildings also need listed building consent. Check with Ealing Council’s planning team before work starts.
Building Regulations. If the chimney serves a working fire or stove, the flue must meet Building Regulations. Your installer or building control can then confirm what’s needed.
Party Wall Act. Many Ealing semis and terraces share a chimney stack with next door. So work to a shared stack can count as work to a party structure. Under the Party Wall etc. Act 1996, a party structure notice must be served at least two months before work starts (legislation.gov.uk; gov.uk guidance).
Scaffold licence. Scaffolding on the pavement or road needs a licence from Ealing Council. Your scaffolder normally applies for it before work starts.
How much does a chimney rebuild cost in Ealing?
Costs depend on:
- partial or full rebuild, and how many courses come down
- the size of the stack and whether it’s shared
- scaffolding (height, access and whether it goes on the pavement)
- matching bricks (reclaimed bricks cost more)
- new pots, flaunching, lead flashing and any roof repairs around the stack
As a national guide, MyBuilder’s chimney repair pricing guide (checked November 2026) puts a chimney stack rebuild at £2,000 to £10,000 or more (MyBuilder). Checkatrade’s April 2026 guide puts chimney flashing repairs at £250 to £1,000 (Checkatrade). London prices tend to sit at the higher end, especially with full scaffolding. Still, only a free survey gives you the real price for your chimney, in writing.

Book a free survey, so we can show you photos of the stack and then give you a written quote.
How long does a chimney rebuild in Ealing take?
First, a partial rebuild is usually two to three days on the stack. A full rebuild above the roofline can take longer than that, often most of a week. Then add time for scaffolding to go up and come down, and any licence or Party Wall notice. Mortar also needs to cure properly, so we avoid frost and heavy rain while we work.
How to choose a chimney builder in Ealing
Before you agree to a chimney rebuild in Ealing, check that the roofer:
- shows you photos of the stack and explains why it needs rebuilding, not just repairing
- tells you whether it’s a partial or full rebuild, in writing
- gives an itemised quote that includes scaffolding, pots, flashing and making good
- can show proof of public liability insurance before work starts
- matches the bricks and mortar to your house
- asks about conservation areas, listed status and shared stacks
- has real Google reviews you can read

Frequently asked questions
How do I know if my chimney needs rebuilding?
Signs include a stack that’s leaning, cracks running through several courses, loose or missing bricks near the top, and badly flaking bricks. If the mortar is only worn but the bricks are sound, repointing is usually enough. Still, a close inspection from scaffolding or a roof ladder tells you for sure.
How much does it cost to rebuild a chimney in Ealing?
MyBuilder puts a chimney stack rebuild at £2,000 to £10,000 or more, depending on size, access and materials. A partial rebuild of the top few courses usually costs less than that, at the lower end. Scaffolding is also a big part of the cost. We then give a free written quote after a survey.
Do I need planning permission to rebuild my chimney?
A like-for-like rebuild is usually treated as a repair. Changing the height or design, or removing the stack, can still need permission. Ealing has 30 conservation areas, and listed homes need consent, so check with Ealing Council’s planning team if either applies to you.
Do I need a Party Wall notice for a shared chimney?
If the stack is shared with next door, work to it can count as party structure work under the Party Wall etc. Act 1996. You should serve a notice at least two months before work starts. Many neighbours agree quickly, but it’s best to sort it out early.
What is flaunching, and is it replaced in a rebuild?
Flaunching is the sloped mortar collar on top of the stack that holds the pots in place and throws rain off the top. When it cracks, water runs straight down inside the chimney. On any partial or full rebuild we form new flaunching, and we’ll often renew it on its own when the rest of the stack is sound.
Can you rebuild a chimney in winter?
Yes, with care. Mortar must not freeze while it cures, so we check the forecast, protect fresh work and avoid frosty days. If the stack is unsafe, we’ll make it safe straight away, then plan the rebuild for the next suitable spell of weather.
Is it better to remove an old chimney than rebuild it?
Sometimes. If you never use the chimney and it’s in poor condition, removal can be cheaper than a rebuild long term. Removal still needs care: builders must support the structure below, and conservation areas may want the stack kept. We’ll give you both options so you can decide.
