Repointing and stack repairs
Mortar joints on a chimney erode faster than those on the walls below because the stack is exposed on all four sides. Once the joints open up, rain soaks into the brickwork, frost breaks the faces off the bricks and damp can show on chimney breasts inside. Raking out and repointing with a suitable mortar stops that cycle before the stack becomes unstable.
- Raking out and repointing weathered joints
- Replacing spalled or frost-damaged bricks
- Checking the stack for leaning or cracking
- Damp staining on chimney breasts traced back to the stack
