HOME > Chimney repairs
If your chimney is showing signs of wear, letting in water or dropping mortar, it’s worth getting it looked at before the problem spreads. At Thistle Roofing Services, we carry out chimney repairs in Chelsea for homeowners and landlords who want clear advice, safe workmanship and repairs that are done properly.


Our service covers chimney maintenance, repointing, flashing repairs, leak tracing, brickwork repairs and chimney rebuild work where required. We begin by checking the visible condition of the chimney stack, the surrounding roof area, the flashing and any obvious weak points. That allows us to understand whether the chimney needs a simple repair or something more substantial.
This service is ideal for homeowners dealing with a leaking chimney, landlords staying ahead of maintenance, or customers who have noticed crumbling mortar, staining near the chimney breast, or signs that the stack is no longer in good condition. A lot of the properties we work on in Chelsea, Hammersmith, Chiswick and Putney have older roof details that need careful attention rather than a rushed patch-up.

Chimneys are exposed to the weather all year round, so they often show wear before other parts of the roof. We regularly deal with loose mortar, cracked flaunching, damaged flashing, leaning brickwork and leaks forming around the chimney stack. In older parts of Chelsea and nearby areas such as Fulham and Kensington, these issues are especially common on period properties where the chimney has been exposed for decades.
When mortar joints start to wear away, the chimney can become vulnerable to water penetration and movement. We carry out chimney repointing in Chelsea to strengthen the structure, improve weather resistance and help prevent more serious damage. If the stack itself has become unstable, we can also advise on structural chimney repairs or a partial chimney rebuild where needed.
Lead flashing around the base of the chimney is there to stop water getting in where the stack meets the roof. If it has lifted, cracked or pulled away, leaks can quickly follow. We provide chimney flashing repair in Chelsea as part of our roofing service, making sure vulnerable joints are sealed properly.
A neglected chimney can lead to more than just a leak. Loose masonry, crumbling mortar and damaged pots can all create safety concerns as well as ongoing water ingress. Dealing with chimney maintenance early usually saves a lot of trouble later on.
We handle everything from minor repairs to more involved chimney work, always starting with a proper inspection and a straightforward explanation of what we find.
