Chimney Repairs & Rebuilding
Chimney Repairs in Darlington: Sound Stacks, Kept Weather-Tight.
Chimney repointing, flaunching, capping, cowls and full stack rebuilds across Darlington, stopping water ingress and making unsafe stacks safe.
The problem we solve
Why you might need chimney repairs & rebuilding.
Chimneys are exposed on all sides to wind, rain and frost, so the mortar joints and the flaunching on top fail faster than the rest of the roof. Once water gets in it travels straight down the chimney breast, causing damp patches, stained plaster and, in the worst cases, a stack that becomes unstable. The fix is to rake out the failed mortar, repoint or rebuild the stack, and seal the top properly.
Signs to look out for
Common signs this work is needed
- Damp patches or brown staining on the chimney breast inside
- Crumbling, recessed or missing mortar between the chimney bricks
- Spalling bricks where the face is flaking off
- Cracked or missing flaunching (the mortar cap holding the pots)
- Loose or leaning chimney pots
- Mortar and brick debris collecting in the fireplace or on the roof below
What's included
A complete, in-house scope.
A chimney stack takes the worst of the weather, and the mortar holding it together slowly crumbles year on year. Left too long, spalling bricks and decayed mortar let water pour down the chimney breast and into your home.
