Expert Chimney Repairs Across Warwickshire

Chimneys are one of the most exposed parts of any property, taking the full force of the weather year after year. Crumbling mortar, damaged flashing, and loose brickwork are all common issues — and all can allow water into your property if left unattended.

Working Safely at Height

Chimney work requires specialist knowledge and safe access. We always use appropriate equipment — scaffolding, tower scaffolds, or secured ladders — and carry full public liability insurance. You can trust us to work safely on your property at all times.

How Much Do Chimney Repairs Cost?

Chimney work covers a wide range. Repointing a stack is typically £400 to £900 depending on size, condition and access. Renewing lead flashings around the base runs £350 to £700. A partial rebuild of the top few courses starts around £900, and a full stack rebuild from roof level can reach £2,500 or more.

Access is the biggest single variable. A chimney on a front elevation with clear driveway access is straightforward; a stack in a rear valley on a three-storey Victorian terrace needs a proper scaffold and is priced accordingly. See our chimney repair cost guide for a fuller breakdown.

How Often Should a Chimney Be Repointed?

A chimney stack takes more weather than any other part of your house — exposed on all four sides with no shelter from wind-driven rain. Mortar in a stack typically needs attention every 20 to 30 years, considerably sooner than the pointing on your walls.

Warning signs are visible from the ground with binoculars: mortar joints receded behind the face of the brick, vegetation growing out of the stack, brick faces flaking or crumbling, and a stack that no longer looks square against the roofline. On period properties we repoint in lime mortar rather than cement — cement on soft Victorian brick traps moisture and spalls the face off.

Should You Repair or Remove an Unused Chimney?

If the fireplace is closed off and you have no plans to use it, taking the stack down to roof level and tiling over removes a maintenance liability permanently. It is often cheaper than a full rebuild and eliminates a common source of leaks.

Worth weighing first: on a period property, chimneys are a defining feature and removal can affect both character and value, particularly in conservation areas. Removal also needs care where a stack is shared with a neighbour in a terrace, and the flue must be properly capped with the loft space ventilated to avoid condensation. We will walk through both options honestly rather than pushing whichever is more profitable.

Signs Your Chimney Needs Attention

• Damp patches on the chimney breast inside, particularly in upstairs bedrooms
• Staining on the ceiling where the stack passes through the roof
• Crumbling mortar or missing pointing visible on the stack
• A cracked, loose or missing chimney pot
• Lead flashing that has lifted, split or pulled away from the brickwork
• White salt deposits on the brick face, showing water moving through the masonry
• A noticeable lean, or daylight visible through the stack

A leaning stack is the one to act on immediately — that is a genuine safety issue, not a maintenance item. If you can see a lean from ground level, keep clear of the area below it and have it inspected without delay.
