Chimney work spans a huge range of jobs - from a £180 flaunching repair to a £3,000 full stack rebuild. The commonest calls are re-pointing eroded mortar, renewing the lead flashing where the stack meets the roof, replacing a cracked flaunching (the mortar bed at the top holding the pot in place), fitting a rain cap or bird guard, or a full rebuild when the brickwork above the roof line has failed. Chimney work is height access work - a decent quote always separates access cost from the actual repair.

Diagnosis matters more here than anywhere else on the roof. A leak that shows up in the chimney breast can come from four different failure points: perished lead flashing (usually the culprit), cracked flaunching letting water into the stack, failed mortar joints on the brickwork above the roof, or a broken pot. A good installer will always send photos before quoting - insist on it, because 'the whole chimney needs rebuilding' quotes from someone who hasn't been up there yet are the classic upsell.
