Chimney Rebuilds

Chimney Rebuilds in Cromer

Chimney stacks on older properties in Cromer take a real battering. The combination of coastal salt air, driving rain from the north, and freeze-thaw cycles through winter means mortar joints erode faster here than they do inland, and soft brick faces spall away over time. A stack that looks solid from the ground can have open joints at the top that are letting water straight into the flue and the surrounding roof timbers.

A chimney rebuild typically starts by stripping the chimney down to a sound course of brickwork - usually at or just below the lead flashing line - then rebuilding upwards using matching brick and a mortar mix suited to the exposure level. The flaunching (the sloped mortar bed at the top that holds the pots) is renewed, the pots are re-bedded, and new lead flashings are fitted to tie the rebuilt stack back into the roof covering. Where a chimney is no longer in use, we can cap the pots and fit a ventilated cowl to prevent moisture ingress down the redundant flue.

Ignoring a deteriorating stack is expensive in the long run. Water in the flue causes damp patches on chimney breasts inside the house, damages ceiling plasterwork, and can saturate roof timbers, leading to rot and insect infestation. In severe cases the stack itself can become unstable - a real safety risk on a terrace where it sits above a neighbouring property.

We always inspect from scaffold before quoting a chimney rebuild, as ground-level assessments miss the detail needed to price accurately. Most chimney rebuilds on standard Cromer terraced or semi-detached properties take one to two days once scaffold is in place. A partial rebuild from the flashing line up typically costs £800-£1,800 in Cromer depending on stack height and brick matching. All structural brickwork carries a ten-year guarantee.

If your chimney breast is showing damp patches or your stack looks uneven from the pavement, call us for a scaffold inspection and written report.
