Chimney Repair

London chimneys take the full force of winter gales and heavy rain, making them prone to cracking and damp penetration. Our skilled masons provide complete chimney restoration, repointing, and lead flashing services to keep your stack watertight.

When You Need Chimney Repair

Crumbling mortar or loose bricks on your chimney stack visible from street level. Damp patches appearing on bedroom ceilings immediately surrounding your chimney breast. A cracked or damaged concrete chimney crown allowing water to seep into the flue. Rusting or displaced lead flashing sealing the joint where your chimney meets the roof tiles.

How We Do It

We examine your chimney stack from scaffolding or ladder access to check masonry and flashing condition. We provide a clear, upfront quote for repointing, brick replacement, or crown rebuilding. We rake out damaged mortar, replace unstable bricks, recast the chimney crown, and renew lead step flashing. We apply breathable waterproofing sealants and clean up all mortar debris from your property grounds.

What to Expect

Standard chimney repointing and flashing repairs typically take 1 to 2 days depending on weather and access.
