Chimney leak repair
Inspection and repair of lead flashings, masonry, pointing, flaunching and roof coverings around chimney stacks.
Inspect every junction around the chimney stack.
Water around a chimney can enter through failed leadwork, open pointing, damaged flaunching, porous masonry or the roof coverings beside the stack. A complete check helps avoid repairing the wrong detail.
Pointing, brickwork and render
Flaunching, pots and cowls
Tiles, slates and underlay around the stack
Typical chimney leak points
Apron and step flashings weather the junction between the stack and roof. Cracks, loose sections or poor laps can allow water behind the covering. Masonry and the top of the stack can also admit water.
Repairing lead and masonry together
Where faults overlap, the quotation can include leadwork, repointing, flaunching and local roof repairs. Treating the whole junction is often more effective than addressing one visible crack.
Unused or unsafe chimneys
Depending on the stack condition and how it is used, repair, capping, partial rebuilding or removal may be considered. Ventilation and the roof finish must be planned before altering an unused chimney.
