Chimney stack repairs and removal into the roof
Chimney flashing, repointing, rebuilding and dropping redundant stacks into the roofline to stop leaks and damp.
Why diagnosis matters
Treat the cause, then repair the damage
Chimney stacks are a frequent source of penetrating damp — failed flashings, eroded pointing and cracked flaunching all let water in. We repair, repoint and reflash stacks, and where a chimney is redundant we can remove it and drop the stack into the roof, making the area watertight.

Common questions
About chimney stack repairs and removal into the roof
Why is my chimney breast damp?+
Damp on a chimney breast is often caused by failed flashings, porous or cracked masonry, or defective flaunching allowing rain into the stack. We inspect the stack and the internal pattern together.
Can you remove a chimney we no longer use?+
Yes. Where a stack is redundant we can remove it and drop it into the roof line, then re-tile and make the roof watertight. We confirm any structural considerations before starting.
Do you repoint and reflash existing stacks?+
Yes. Where the stack is sound we repoint the joints, renew the flaunching and dress new lead flashing into the mortar to stop water tracking in.
Is the specialist survey really free?+
Yes — completely. We offer every homeowner and property manager across Dorset, Hampshire and Wiltshire a complimentary specialist survey at no charge. This includes an on-site inspection, written findings, a clear scope of any recommended work, and an honest referral if the problem falls outside what we do. You pay nothing for the survey. You only pay if you commission the remedial work, and you are under no obligation to do so. The reason we do this is straightforward: we believe in diagnosing the problem before recommending a treatment. A proper inspection takes time, and we'd rather invest that time up front than quote a solution before we've understood the cause.
Not sure if this is your problem?
That's exactly what the survey is for. Book your complimentary specialist survey and one of our experienced team will identify the cause on-site, consider the alternatives, and give you written findings — at no charge and with no obligation.
