Damp on the chimney breast

London's chimney stacks are old and tall, and they take the weather from every side. Mortar washes out of the joints, the flaunching on top cracks, pots loosen, and the lead where the stack meets the roof lifts or splits. Water then runs down inside the stack and shows up as damp on the chimney breast.

We get up to the stack, find where the water is getting in and put it right: repointing, new flaunching, pots re-bedded or capped, and new lead flashing and soakers where the old lead has failed.

10/10

Three quotes, chose Masterfix

Materfix roofing and guttering Ltd came out and inspected my roof as I was having a leak in my bedroom ceilings. They gave me a quote and I also got more quotes from 2 other companies which were around the same price. I decided to go with masterfix. They came out the next week and did a very good job. Very well manoured bunch of lads and would highly recommend them to anybody. Thanks again

Leadwork

Lead flashing seals every joint where a roof meets brickwork: chimneys, walls, dormers and valleys. When it lifts or cracks, water goes straight in. We cut and dress new lead to fit, and dress it into the brickwork properly so it stays put.

Leaks round a chimney are often roof faults. See roof repairs if the problem is the tiles round the stack.

Straight answers before you book

How much does a chimney repair cost?
It depends on the work and the access. The inspection is free and the price is in writing before we start.
Why is my chimney breast damp?
Usually failed pointing, cracked flaunching or lifted lead flashing. We find which one and fix it.
Can you cap a chimney I do not use?
Yes. A cap or cowl stops rain coming down the flue while keeping it ventilated.
Do you do leadwork?
Yes. We fit new lead flashing to chimneys, walls, dormers and valleys.
