Chimney Repairs in Portsmouth & Hampshire
Repointing, flashing, cowls and full chimney rebuilds across Portsmouth and Hampshire.
Old chimneys are the most weather-beaten part of any roof, and Portsmouth's coastal position makes it worse — salt air, driving rain off the Solent, and exposed positions on Victorian and 1930s housing all accelerate mortar failure and lead corrosion. A neglected chimney isn't just a leak risk; a failing stack with crumbling brickwork or a rotted crown is a genuine safety hazard, especially in storms. We repoint, re-flash, rebuild and remove chimneys across Portsmouth and Hampshire, always on full scaffolding — never ladder work above gutter line. Lead is code 4 minimum, dressed properly and clipped, never silicone-stuck. Mortar is matched in colour and mix to the existing stack. We won't quote a chimney without inspecting it from the front, back and roof level first. Most chimney work is finished in 1-3 days once scaffolding is up. Free written quote within 48 hours.
What we fix
Chimney repointing
Raking out old failed mortar and re-pointing in a properly mixed lime or NHL mortar matched to the original. Lasts 25-30 years done right.
Lead flashing repair and replacement
Code 4 or 5 lead, dressed and clipped to the brickwork. Common cause of chimney leaks — fixed properly is fixed for decades.
Chimney cowl fitting
Anti-downdraft cowls, bird guards, rain caps and capping plates. Stops nesting, downdraft and rain entry to disused flues.
Crown rebuilds
The concrete cap on top of the stack — cracks let water straight into the brickwork. Rebuilt in proper mortar with a weathered fall.
Pot replacement and refitting
Cracked or missing pots replaced. Rebedded properly into fresh flaunching, not just stuck on with silicone.
Full chimney rebuilds
From roofline up where the existing brickwork is past saving. Matched bricks, proper bonding, lead trays where structurally appropriate.
Chimney removal
Where a chimney is unused and unsafe. Down to roof level or all the way through. Structural sign-off arranged where required.
Damp and condensation repairs
Damp on the chimney breast usually traces to flashing, capping or pointing — diagnosis first, not just a re-skim of the wall.

Visible gaps in the mortar joints, lumps of mortar in the gutter, brickwork that looks soft or 'frilly' at the edges. If you can dig a screwdriver into the joint with no resistance, it's overdue. Best checked from a drone photo or roof-level inspection — we do both.
