Chimney repairs in Doncaster
A chimney takes the weather on every side, so loose mortar, failed flashing and slipped tiles around it are a common source of leaks and damp. Here is what each repair costs and what to ask before anyone goes up.
Is it a chimney job?
Checkatrade's Doncaster roofer page lists chimney repointing and flashing repair among the common roofing jobs in the town[1].
Checkatrade says it is worth speaking to a specialist as soon as you see signs of damage or suspect a leak, especially if water is getting in, bricks or mortar are loose, or there are damp patches near the chimney[2].
What chimney repairs cost
- Up to five tiles around the chimney: £170 to £500 for up to five tiles[2]
- Chimney cap: £180 to £520[2]
- Flashing repair: £250 to £1,000[2]
- Repointing: £300 to £1,000[2]
- New liner: around £250 per metre, supplied and fitted[2]
- Removing the stack: £260 to £340 per metre, or around £1,800 for the whole job[2]
These are Checkatrade's UK figures. Checkatrade's UK guide says most chimney repairs cost between £180 and £1,000, depending on the work needed[2].
Why chimneys leak
Checkatrade says damaged flashing, the waterproof seal where the chimney meets the roof, is one of the most common causes of chimney leaks[2].
Scaffolding and the quote
Checkatrade says scaffolding is often one of the largest extra costs in chimney repair, so check whether it is in the quote and how long it will stay up[2].
Checkatrade says a written quote should confirm the repair needed, the cost of any scaffolding and how long the work should take[2].
How long it takes
Checkatrade says minor chimney repairs can often be done in a day, repointing or flashing repairs may take one to three days, and structural work or removal can take several days or longer[2].
After a storm
Checkatrade's Doncaster roofer page lists damaged chimneys or guttering among common emergency roofing jobs, alongside storm damage and flashing failure[1].
Checkatrade says home insurance may cover chimney repairs when the damage comes from an insured event such as a storm or fire, but normal wear and tear usually isn't covered[2].
Shared chimneys
Checkatrade says chimney repairs are usually the property owner's responsibility, and in shared properties the responsibility may be split between neighbours or set out in the property agreement[2]. On a semi or terrace, talk to the neighbour before work starts.
