Chimney Stack Repairs & Repointing In Slough

Water ingress around a chimney is a common problem in Slough and Uxbridge homes. Usually, the culprit is the lead flashing. This is the metal seal that wraps around the base of the stack. If the lead has cracked or pulled away from the brickwork, rainwater will run straight down into your roof space. We carry out high-quality leadwork repairs, using Code 4 or Code 5 milled lead to create new aprons, step flashings, and soakers. We dress the lead properly into the mortar joints, creating a permanent, waterproof barrier that handles the expansion and contraction of the metal during the changing seasons.

The "flaunching" is the sloped bed of mortar at the very top of your chimney that holds the chimney pots in place. Because it sits right at the peak, it bears the brunt of frost and heat. In many older properties in Maidenhead and Slough, the flaunching has cracked over decades of freeze-thaw cycles. Once it cracks, water gets into the stack, leading to dampness inside the flue. We remove the old, crumbling concrete and apply a fresh, strong mix that sheds water away from the pots. If your chimney pots are loose or damaged, we can reset or replace them at the same time to make the top of your roof secure.
