Chimneys & Leadwork in Burgess Hill
A chimney leak in Burgess Hill may come from mortar, flashing or the roof covering where they meet. We work on these junctions and nearby masonry.
Chimney and flashing faults in Burgess Hill
A stain near a chimney breast does not necessarily mean the lead flashing has failed. Rain can enter through open pointing, cracked flaunching around chimney pots or a damaged cap, then travel through the stack before it appears indoors. We check the masonry and the roof junction to find the likely source.
The lead around a chimney works in sections. Aprons, step flashings, soakers and back gutters each guide water away from a different joint. Repointing can deal with open mortar, while damaged lead needs a repair to the metalwork; surface sealant alone is unlikely to make a failed junction sound.

Burgess Hill residential roofs range in age and material. A broken tile may be all that needs replacing, but worn battens or a failing roof edge can turn a small leak into wider work.

Questions about chimneys & leadwork in Burgess Hill
Why is rain reaching a chimney breast in Burgess Hill?
The source may be mortar, brickwork, a chimney top, flashing or the roof covering alongside it. Checking these details together is more useful than assuming the lead is at fault.
Can a chimney be repaired without rebuilding it?
Local mortar, flashing or masonry repairs may be possible when the remaining structure is sound. The extent of deterioration determines whether a larger repair is needed.
Is a chimney leak always caused by the flashing?
No. Failed pointing, flaunching, brickwork or adjacent tiles can let rain in around a chimney too. The repair depends on which detail has failed.
Can lead flashing be repaired?
Sometimes. The extent of damage, the age of the lead and the quality of existing detailing determine whether repair or renewal makes more sense.
What are the signs that a chimney needs repointing?
Open or crumbling mortar joints, loose material on the roof and damp around a chimney breast can be clues. Damp may have another cause, so the stack, flashing and adjacent roof should be checked together.
