Chimney Repairs

Chimney Repairs Across Surrey & Hampshire

Chimney stacks take more weathering than almost any other part of the building — exposed on all four sides at the highest point of the roof. Crumbling mortar, failed pointing, loose pots, and deteriorated lead flashings are all serious defects that can allow water into the structure, cause internal ceiling stains, and ultimately compromise the stack itself.

M3 Roofing carries out full chimney inspections with drone or close-access scaffold survey, so you know exactly what condition your chimney is in before any work is priced.

Repointing Done Properly

Incorrect mortar selection is a very common problem — using cement-rich mixes on Victorian brickwork causes spalling and accelerated decay. M3 Roofing always recommends and uses the correct mortar specification for the age and brick type of your stack, helping it last decades rather than failing prematurely.
