Chimney Repairs in Polegate

Chimney repairs in Polegate cover the full range of chimney maintenance — repointing, lead flashing replacement, pot replacement, stack rebuilding and chimney removal where required. We cover all of Polegate and the BN26 area with free surveys and no call-out fee.

The predominantly 1930s–50s semi-detached and detached with some post-war infill development in Polegate means that many chimney stacks were built with materials and mortars that are now at the end of their design life. The local inland frost-pocket in the Cuckmere valley — sharper overnight frosts than coastal Eastbourne, causing accelerated mortar and valley joint deterioration accelerates mortar deterioration — particularly on the north and west-facing sides of stacks. The most common chimney repair calls from Polegate involve valley gutter failures on 1930s–50s stock; nail sickness on post-war concrete tile; freeze-thaw mortar failure on chimney stacks.

Mortar selection is critical on chimney repairs. Modern sand/cement mortar is too hard for Victorian and Edwardian brickwork — it forces movement stress into the brick rather than the mortar joint, causing accelerated spalling. We use natural hydraulic lime (NHL) mortar on all pre-1940 chimney stacks as standard.

How We Inspect Chimneys in Polegate

Chimney inspections in Polegate cover the full stack from flaunching at the top to apron flashings at the base. We check pointing condition, lead code and lapping detail, pot and cowl integrity, and chimney breast condition below the roofline. Most Polegate chimney problems are identified visually from the roof — we get on the roof for every survey, not just the ladder.

Repointing vs Rebuilding in Polegate

Repointing is appropriate when the masonry is sound but the mortar joints have eroded or cracked. On pre-1940 Polegate chimneys, we use NHL lime mortar — sand-cement mortar is too rigid and accelerates masonry damage. Rebuilding is required when the stack has moved, the internal flue structure is compromised, or more than 40% of the mortar joints are failed. We tell you honestly which is needed.

Lead Flashings on Polegate Chimneys

Lead flashing failure is the most common cause of chimney-related water ingress in Polegate. Code 4 lead minimum on all Polegate properties — code 3 is insufficient for the thermal cycle here. Flashings are cut and dressed correctly — not bedded in frame sealant, which is a temporary fix. All lead work on Polegate chimneys is covered by our 10-year workmanship guarantee.

If your chimney has visible mortar loss, staining on the chimney breast internally, or a pot that looks unstable, call us for a free survey. We cover High Street, Wannock Road and all of Polegate.
