Chimney Repairs & Leadwork
Expert Chimney Repairs You Can Trust
A chimney takes more weather than any other part of the roof. Frost breaks down the mortar joints, the cement crown on top cracks, and the lead flashing where the stack meets the tiles can lift or split. Any of these lets water run into the brickwork and down into the rooms below, often showing as damp patches on a chimney breast. TNR repairs chimneys on homes and commercial buildings across Hertfordshire, Hampshire and Surrey to stop that happening.
Leadwork is the other half of this service. Lead flashing seals the joints between the roof covering and walls, chimneys and dormers, and when it fails, leaks follow. We repair and replace flashing, repoint tired brickwork, rebuild crowns and flaunching, and fit new chimney pots, caps and cowls. Each job begins with a free inspection of the stack, so you know exactly what needs attention and why before agreeing to any work.

Why choose us
Why Choose TNR for Chimney and Lead Work
Free Stack Inspection
We check the brickwork, crown, pots and flashing before quoting, so the repair targets the real cause of the damp.
Masonry and Lead Together
Because we handle lead flashing as well as brickwork, the stack and its roof junction are repaired as part of the same job.
Pots, Caps and Cowls
Replacing a pot or fitting a cowl alongside other repairs saves paying for access to the chimney twice.
Insured Work at Height
Chimney repairs mean working high above the roof line, and our public liability insurance covers that work on your property.

- The amount of lead flashing to be repaired or renewed.
