What is chimney damp?
Chimney damp is a common issue that causes damp patches, yellow stains, flaking paint,
and sometimes a musty smell around your chimney or fireplace. Moisture can get into
chimneys through uncapped tops, broken flashing, or cracked mortar, leading to damage
over time. Spotting and fixing these signs early can help protect the structure and keep
your home warm and dry.

Types of chimney damp we treat
One of the most common sources of chimney damp is rainwater entering through open or damaged chimney pots. When left uncapped, rain can seep in, causing damp patches around the chimney breast. Our team can fit or repair chimney caps, cowls, and flashing to seal out moisture effectively while allowing airflow.
Blocked chimneys, whether sealed at the top or bottom, often suffer from condensation build-up, especially in unventilated areas. This trapped moisture can lead to damp patches around the chimney breast. We address this by installing proper ventilation at the top and base of the chimney, providing a steady flow of air that keeps the area dry.
Over time, chimney masonry and mortar joints can degrade, allowing rainwater to penetrate. Cracked or crumbling mortar often leads to damp problems within the chimney stack and nearby walls. Damp HQ offers expert repointing services, sealing cracks and restoring the masonry to prevent future moisture from entering.
Lead flashing around the chimney stack is vital for sealing joints where the chimney meets the roof. Damaged or worn flashing can let rainwater seep into the chimney, causing damp issues throughout the structure. Our team replaces or repairs flashing to create a secure, water-resistant seal.
Older chimney stacks, often with porous bricks or weakened mortar, are more vulnerable to water seepage, leading to penetrating damp. Water travels through the brickwork and into the walls surrounding the chimney breast, leaving visible stains or damp patches. We apply a specialist water-repellent treatment to protect the masonry from future weather damage and prevent further water ingress.
Rising damp can occur when moisture rises from the ground into the base of the chimney. This is common if there’s no damp-proof course or if it has been bridged by debris. Signs include damp marks or salt deposits near the base of the chimney breast. To tackle this, we can install a chemical damp-proof course to stop moisture from rising, along with removing any contamination to prevent recurring issues.
