Chimney Repairs in the UK in 2026, and What Drives the Price
Chimney work needs scaffold, the right materials (lime mortar for older property, sand and cement for newer), and proper lead. Here is what actually sets the price on the common jobs.
Key takeaways
- Repointing is priced on stack size, how many joints are raked out and how the stack is reached.
- A rebuild from the roof line costs more because of scaffold, brick matching and time on the stack.
- Removal to roof level depends on size, how much brickwork comes down and how debris is taken off.
- Lead flashing is priced on the length of the detail and how complex the abutment is.
- Always include scaffold cost in the comparison.
Repointing
Rake out failed mortar to a proper depth (not just a quick scrape), repoint with appropriate mortar. Lime for pre 1920s property to allow movement. Sand and cement for modern. The price follows the size of the stack, how many joints need raking out and whether scaffold is needed to reach it safely.
Rebuild
If the stack is leaning or the bricks are spalled, full rebuild from the roof line up. Reclaimed brick to match the existing where needed. New pots, flaunching, lead flashing. Cost follows the height of the stack, how far down it has to come, the brick being matched and the scaffold that elevation needs.

Removal
Remove down to roof level, weather in with battens, felt and matching tile or slate. From the outside you cannot tell where the chimney was. Size, how much brickwork comes down and how the debris is taken off the roof all move the price, and scaffold is costed on top.
Lead flashing
Strip failed lead, dress new code 4 or code 5 lead into chase cuts in the brickwork, seal with lead mate. Price depends on the length of the run and how complex the abutment is. Done right it lasts 60 plus years.
