How the price is built up
A big part of any chimney job is getting safe access to the roof, so scaffolding or a tower often costs as much as the repair itself. On top of that you pay for the skilled labour and any materials, such as lead, mortar or a new pot. Most of the cost is labour and access. Materials like mortar, a pot or a cowl are fairly cheap, but lead flashing and scaffolding hire add up quickly.
Ways to keep the cost down
- Combine chimney work with other roof or gutter jobs while the scaffolding is up
- Repoint the stack before it needs rebuilding, as small repairs are far cheaper
- Ask whether an access tower is cheaper than full scaffolding for a quick job

Common questions
How much does chimney repair cost in 2026?
Chimney repairs typically cost £250 to £3,000 in 2026, with most people paying around £750. A new pot or cowl or a small flashing repair can be £150 to £600, repointing or re-rendering the stack runs £450 to £1,200, and a partial rebuild is £1,000 to £3,000.
What affects the cost of a chimney repair?
The main factors are the type of repair, how easy the stack is to reach and whether scaffolding is needed. A tall or awkward stack, a full rebuild rather than a patch, and higher labour rates in the South East all push the price up.
Why does scaffolding add so much to the cost?
Because the work is at height, a roofer usually needs scaffolding or an access tower to work safely. That access often adds £300 to £800 and can cost as much as the repair itself, which is why bundling jobs while it is up saves money.
Can I repair a chimney myself?
It is not advised. Chimney work means working at height on a roof, handling lead and getting the mortar and weathering right. Poor repairs let water in and cause bigger damage, so most people use a roofer or chimney specialist.
How long does a chimney repair take?
Most repointing and flashing jobs take one to two days once access is set up. A partial rebuild usually takes three to five days, plus the time to put up and take down the scaffolding.
Is it cheaper to remove the chimney than repair it?
If the chimney is no longer used, removing the stack or the whole breast can be an option, but it is not always cheaper once scaffolding, making good the roof and building work are counted. A repair is usually the lower-cost choice if the stack is sound.
