Chimney Repairs in Walthamstow
Chimney Repair and Leadwork in Walthamstow
A brown stain spreading down a chimney breast, wallpaper lifting beside the fireplace or a musty smell in an upstairs room are often the first signs that water is getting into a chimney. Left alone, damp in a chimney breast can spread into nearby walls and ceilings and spoil decoration. Ashlar Roofing carries out chimney repairs in Walthamstow, across E17 and the London Borough of Waltham Forest, finding where the water enters and putting it right.
The cause is usually found at roof level. Lead flashings can split or pull out of the mortar joint, the flaunching around the pots can crack, and weathered brickwork can soak up rain like a sponge. An uncapped flue lets water fall straight down inside. A capped flue with ventilation stops rain entering while letting the chimney breathe. We inspect the stack, explain what we found and quote for the repair before any work is carried out.


What's included
What Chimney Repair Work Covers
The main parts of the job, each listed in your quote.
- Repointing worn or missing mortar joints, which keeps rain out of the brickwork and stops the stack weakening.
- New lead flashings where the stack meets the roof, the junction most often behind leaks near a chimney breast.
- Rebedding or replacing chimney pots, so they sit securely and are not a risk in high winds.
- Renewing or repairing the flaunching, the mortar cap around the pots that sheds rain away from them.
- Caps or cowls for unused flues, reducing rain entry while keeping enough ventilation to avoid damp.
- Rebuilding or reducing damaged stacks where repairs alone would not make them safe, subject to any planning requirements.

- Shared stacks on terraces, where the work may involve the neighbouring side
- Matching bricks, mortar, lead or pots to the existing chimney
