Chimney problems are often the first sign of a roof in trouble. Crumbling mortar, leaning stacks, damp on the chimney breast, or rainwater finding its way down inside the flue — coastal weather in Portsmouth and Hampshire is hard on chimneys, and most older properties need repair work at some point. The Victorian and Edwardian terraces of Southsea, Albert Road and Fratton, the 1930s semis around Cosham, Drayton and Fareham, and the post-war stock across Havant and Waterlooville all share the same story: lime-mortared stacks that have weathered 70 to 130 winters with very little maintenance. If you've spotted a damp patch near a chimney breast, or pieces of mortar in the gutter, the chimney is almost always the cause — water ingress damages plaster, insulation and roof timbers long before you see anything from the ground. Our approach is honest inspection first: if a stack can be repointed rather than rebuilt, that's what we'll quote for. If you're worried about your chimney, we'll come out, take photos from up close, and give you an honest written quote within 48 hours.

What we fix

Chimney repointing

Replacing failed mortar between brickwork. The most common chimney repair, usually solving damp problems and extending the chimney's life by 20+ years.

Lead flashing repair and replacement

The lead seal where the chimney meets the roof is one of the most common failure points. We replace with new code 4 or code 5 lead and proper mortar bedding.

Chimney cowl fitting

Anti-downdraft cowls, bird guards, rain caps and gas terminals. Stops downdraft, water ingress, nesting birds and squirrels.

Chimney crown rebuilds

The concrete cap on top of the chimney that protects the brickwork. When it cracks, water gets into the stack and freezes — accelerating damage every winter.

Pot replacement and refitting

Cracked, missing or wobbly chimney pots replaced with terracotta or clay pots properly flaunched in.

Full chimney rebuilds

When the stack is leaning, mortar has failed throughout, or brickwork is too damaged to repair, we rebuild from the roofline up using matching brick and original profile.

Chimney removal

For unused chimneys that are unsafe or expensive to maintain. Complete removal, roof made good, often significantly cheaper than ongoing repairs.

Damp and condensation diagnosis

Damp on a chimney breast isn't always the chimney's fault. We diagnose the actual cause (cap, flashing, pointing, blocked flue, internal condensation) before recommending work.
