Crumbling Mortar Lets Water Into Your Home
Chimney mortar joints take a relentless beating from wind, rain, frost and UV exposure. Over 20 to 30 years, even well-mixed mortar erodes and begins to crack, recede and fall away. Once the joints open up, rainwater soaks into the brickwork and works its way down through the stack. The result is damp patches on chimney breasts, staining on ceilings, and — in severe cases — structural instability as freeze-thaw cycles break the bricks apart from within.
Radiant Roofing carries out chimney repointing across Kent, Sussex and Surrey. We rake out all failed mortar, brush and wash the joints clean, and repoint with a suitable mortar — lime-based for older, softer brickwork, or a cement-based mix for modern stacks. Every joint is finished to match the original pointing style, leaving your chimney fully weatherproofed and looking as it should.

Frequently Asked Questions
Chimney repointing typically costs between £300 and £1,500 including scaffold. A standard single-flue stack costs £300 to £600, while a large multi-flue chimney requiring full repointing on all faces runs £800 to £1,500. Scaffold is usually the biggest single cost, which is why we recommend combining repointing with any other chimney work needed.
Correctly specified chimney repointing lasts 25 to 40 years. The key is using the right mortar — lime mortar for older, softer bricks, cement mortar for modern stacks. Using cement on soft bricks can actually cause more damage, which is why choosing an experienced contractor matters.
We use whichever is appropriate for your brickwork. Older properties — typically pre-1920 — were built with soft lime mortar, and repointing them with hard cement can trap moisture and crack the bricks. We use lime mortar for these chimneys. Modern chimneys built with engineering or Fletton bricks are suitable for cement mortar.
We cover Kent, East Sussex, West Sussex and Surrey. Our teams regularly repoint chimneys in Tunbridge Wells, Crowborough, Sevenoaks, Tonbridge, Uckfield, Haywards Heath, East Grinstead and surrounding areas.
