The usual suspect

Chimneys are where roofs leak

Tall, exposed and full of joints, the chimney stack takes more weather than almost any part of the roof — so it's no surprise it's behind so many leaks. Eroded pointing, cracked flaunching, failed lead flashing and uncapped flues all let water into the structure below.

We repair the whole stack rather than just the symptom: raking out and repointing the brickwork, renewing the flaunching around the pots, re-dressing the lead where the stack meets the roof, and fitting cowls to redundant flues. Where a stack is beyond repair, we can rebuild or take it down and weather over.

Chimney work we do

  • Repointing eroded and cracked mortar joints
  • New flaunching to secure and weather the pots
  • Lead flashing and soakers to the stack renewed
  • Cowls fitted to redundant or damp-prone flues
  • Unsafe or leaning stacks rebuilt
  • Chimneys taken down and weathered over

Chimney repair questions

Do you repair chimneys and repoint brickwork? +
Yes. We carry out the full range of chimney work — repointing eroded mortar joints, renewing the flaunching that holds the pots, replacing cracked or slipped lead flashing at the base, fitting cowls, and rebuilding stacks that have become unsafe.
Why is my chimney causing a leak? +
Chimneys are one of the most common sources of roof leaks. Water gets in through cracked flaunching, eroded pointing, failed lead flashing where the stack meets the roof, or a redundant flue with no cowl. Because the leak often shows up some distance away inside, it's worth having the whole stack checked properly.
Should I remove or cap an unused chimney? +
If a chimney is no longer used, capping it with a vented cowl keeps rain out while still letting the flue breathe to prevent damp. Full removal is an option too, but capping and weathering the stack correctly is usually the simpler, cheaper way to stop leaks and damp.
Is my chimney safe? +
Leaning stacks, loose pots, crumbling mortar and cracked flaunching can all become a safety issue, particularly on tall Victorian stacks exposed to West London's weather. If you have any concerns, we can inspect the chimney and advise on whether it needs repointing, re-flaunching or rebuilding.
