Chimney Repairs
Repointing, lead flashing repairs, pot and cowl fitting, stack rebuilding, and chimney maintenance for period and modern properties — Legacy Roofing covers Berkshire and London.
Chimney stacks are exposed to more weathering than almost any other element of a building. They project above the roof line, facing full wind and rain exposure, and they are built from individual bricks and mortar joints that erode over time. In Berkshire's older towns — the Victorian terraces of Reading's inner suburbs, the Edwardian semis of Woodley and Earley, the Georgian and Victorian properties around Wargrave and Wokingham town centre — chimney maintenance is a recurring necessity rather than an exceptional event.
Legacy Roofing carries out the full range of chimney repair work across Berkshire and London. Stack repointing is the most common job: over time the mortar joints between bricks open up, allowing water to track down the inside of the stack and saturate the breast below. We rake out failed joints and repoint in a lime-compatible mix that will flex with the stack rather than crack away.
Lead flashing work around chimneys is equally important — a failed back-gutter or step flashing lets rainwater run directly behind the stack and into the roof space. We address these as a coordinated repair rather than patching one element without the other.
Where pots, cowls, or flashband repairs have been used as a previous bodge, we assess honestly whether a proper repair or consolidation is the right approach. If a stack needs partial or full rebuilding we carry that out too.

Chimney Repairs — Common Questions
Very often yes. The most common causes of damp chimney breasts are failed pointing on the external stack, deteriorated lead flashings at roof level, or a missing or cracked pot allowing water into the flue. We will diagnose the cause before recommending a fix.
Yes — we can install a fitted ventilating capping that prevents water entry while allowing the flue to breathe. This is usually the right approach for decommissioned stacks.
For most chimney work above two storeys, yes. We include scaffolding in the quote and arrange it as part of the job.
Spalling and powdering mortar is a sign that water has been getting in for some time and the frost-thaw cycle has broken down the joint. It should be addressed — eroded joints let more water in and the damage accelerates.
