One assessment for stack and roof junction
Masonry condition checked
We inspect bricks, mortar, flaunching, pots and caps for defects.
Flashing included
Leadwork around the stack is checked as part of leak diagnosis.
Safe access planned
High-level inspection comes before deciding the repair scope.
Check every exposed part of the chimney
A chimney stands above the roof where wind and rain reach every side. Mortar joints can wash out, bricks can deteriorate and flaunching around pots may crack. Caps, pots and the roof junction can also let water in. When arranging chimney repair in London, we inspect the complete visible stack rather than assuming damp comes from one loose joint. Warning signs include crumbling mortar, loose masonry, debris below and staining around the chimney breast. Because these problems occur at height, safe access is essential for a close assessment and for protecting people and property while repairs take place.
Repair the stack and seal its roof junction
The suitable work depends on what has deteriorated. Local masonry repair or repointing may restore worn areas, while defective flaunching or weathering details can require renewal. We also assess the chimney flashing because failed leadwork often allows rain through the point where the stack meets the roof. Tiles, slates or flat-roof material around that junction may need local reinstatement too. By considering the masonry and covering together, we can address the route water takes rather than tidying the stack while leaving a gap below.
Frequently asked questions
Can damaged chimney flashing cause damp indoors?
Yes. Flashing seals the junction between the stack and roof covering. Splits, lifting or failed laps can let water pass behind it. We inspect the leadwork, masonry and nearby covering to identify the actual route.
What are the signs that chimney mortar needs repair?
Crumbling joints, loose fragments, open gaps and damp around the chimney can all justify inspection. The visible condition from ground level may not show the whole defect, so safe high-level access may be needed before defining the work.
Do you repair the roof covering around a chimney too?
Yes. Chimney-related leaks can involve tiles, slates, underlay or other covering beside the stack. We assess these areas with the masonry and leadwork, then include the necessary local reinstatement in the repair plan.
