Repair versus rebuild
Repointing and flashing repairs handle localised wear. A rebuild becomes the right call once the structure itself is compromised — leaning brickwork, widespread cracking, or a stack that's clearly moved.
It's rarely all-or-nothing
In many cases only the upper section of a stack needs rebuilding, with the lower structure staying sound. A proper inspection tells you which situation you're actually in before any work starts.
Matching the existing property
Where possible, replacement bricks are matched to what's already there, so a rebuilt stack doesn't stand out against the rest of the roofline.
What causes it to get this far
Long-term water penetration, storm damage, and simple age are the usual culprits — a chimney that's been left without maintenance for decades is a common candidate.
A typical timeline
Most rebuilding projects take two to five days depending on the size of the stack and extent of the work, considerably less disruptive than people often expect.
If a chimney inspection has flagged structural concerns, our team can advise honestly on whether a rebuild is genuinely needed or a repair will do.
