Chimney Repair across the UK

Chimney Repair - what to expect

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.

For a mid-range job (renew lead flashings + repoint the exposed brickwork + new flaunching + rain cap), expect £600-£1,200 including scaffold. A full rebuild above roof level is £1,500-£3,000 depending on stack height and access. Below that, a Code 4 lead flashing renewal alone is around £400-£700 and often solves the leak on its own. Anything involving the flue liner is a specialist HETAS job, not general roof work.
