Chimneys
Chimney Repairs
Chimneys are exposed on every side. Regular attention keeps them weathertight and helps prevent leaks where they meet the roof.
About this service
Chimney Repairs from Master Roofing & Flat Roofing
Chimney stacks suffer from frost, wind and rain on all faces. Mortar erodes, flaunching cracks, pots loosen and flashing at the base can fail — all of which can lead to damp inside.
We assess the stack and its junction with the roof and recommend the repairs needed, from minor pointing to rebuilding sections where necessary.
Common chimney problems
- Eroded or missing mortar joints
- Cracked flaunching around the pots
- Loose or damaged chimney pots
- Failed flashing at the base of the stack
- Spalling or damaged bricks
- Damp on chimney breasts inside
