Chimney repair, repointing, flaunching, removal and capping across Kent, Sussex and Surrey.
About Our Chimneys & Repointing Services
Chimneys are one of the most exposed parts of any building, standing above the roofline and taking the full force of wind, rain and frost. Over time, mortar joints erode, flaunching cracks, lead flashings lift and brickwork deteriorates. A neglected chimney can allow water to penetrate deep into the roof structure, causing damp, timber rot and staining on internal walls and ceilings — problems that are far more expensive to fix than the chimney repair that would have prevented them.
Radiant Roofing provides a comprehensive chimney service covering repairs, full repointing, flaunching renewal, chimney capping and cowls, lead flashing replacement and complete chimney removal where a stack is no longer needed. We also carry out brick repointing on gable walls and other areas of exposed brickwork that are showing signs of mortar failure.
If your chimney mortar is crumbling, your flaunching is cracked, or you have noticed damp patches near the chimney breast inside your home, do not delay. Contact us for a free inspection and we will provide an honest assessment of the work required along with a clear, written quotation.

Our Chimneys & Repointing Services

Chimney Repointing
Eroded mortar joints raked out and repointed with a suitable lime or cement mortar. Proper repointing restores weather protection and extends the life of the brickwork by decades.

Chimney Flaunching
Cracked or crumbling flaunching removed and replaced with a new mortar cap. Correctly shaped flaunching sheds water away from the chimney pot and prevents ingress into the stack.

Chimney Removal
Redundant chimney stacks removed safely back to roof level or below. We tile over the opening, install appropriate ventilation and ensure a weathertight, invisible finish.

Chimney Capping & Cowls
Disused chimney pots capped to prevent rain, birds and debris entering the flue while maintaining ventilation. We fit terracotta, metal and mesh cowl options to suit every chimney.

Frequently Asked Questions
The cost of chimney repointing depends on the size of the chimney, the extent of the mortar failure and whether scaffolding is required. A typical single-stack chimney repoint costs between £400 and £1,000. Larger stacks, full flaunching renewal or additional lead flashing work will increase the cost. We provide free, written quotations with no hidden charges.
Most chimney repairs — including repointing, flaunching and lead flashing work — are completed within one to two days. A chimney removal typically takes one day plus an additional day for tiling and finishing. We always confirm the expected timeline before work begins.
The most obvious signs are crumbling or missing mortar between the bricks, loose or displaced bricks, damp patches near the chimney breast inside the house, and white salt deposits (efflorescence) on the brickwork. If you can see daylight through the mortar joints or mortar dust collecting on the roof tiles below, repointing is overdue.
Yes. If a chimney is no longer in use, we can remove it back to roof level or even below roof level depending on the structure. We tile over the opening with matching tiles, install ventilation to prevent condensation in the former flue and ensure a completely weathertight finish. Chimney removal reduces maintenance costs and eliminates a common source of leaks.
We cover the whole of Kent, Sussex and Surrey, including Tunbridge Wells, Sevenoaks, Tonbridge, Maidstone, Crawley, East Grinstead, Haywards Heath, Reigate and the surrounding areas. If you are unsure whether we cover your location, give us a call and we will be happy to confirm.
It depends on the age and type of your brickwork. Older properties built with soft, lime-based bricks should be repointed with lime mortar, which is softer and allows the brickwork to breathe. Using hard cement mortar on soft bricks can cause the bricks themselves to crack and spall. For modern properties with engineering bricks, a cement-based mortar is appropriate. We always assess the brickwork before recommending a mortar type.
