Chimney Rebuilds

Chimney Rebuilds in your area

Chimney stacks on Cambridge properties — particularly on the Victorian and Edwardian terraces common in areas like Petersfield, Mill Road, and the Kite — take decades of weathering. Brickwork spalls and cracks, mortar joints erode, and flaunching around the pots cracks and lifts, allowing water to pour down the inside of the stack. In serious cases, the stack can lean or become structurally unstable, which is a safety risk to anyone below.

A chimney rebuild involves erecting scaffold to give safe, stable access to the full height of the stack. We then take down the existing brickwork to a sound course — often just above or at roof level — and rebuild using matching brickwork where possible, or a close match where the original stock is no longer available. New lead flashings are dressed in at the same time. Flaunching around the pots is re-done in fresh mortar, and pots are re-bedded or replaced. We check the internal flue lining condition while the stack is open if the chimney is still in use.

Chimney work without proper scaffold is dangerous and produces a poor finish. Working from a ladder at stack height does not give a roofer the stability or space to lay bricks accurately or dress lead properly. Scaffold also protects the roof below from falling debris during the strip-out.

We agree the scope of the rebuild after a visual inspection from ground and roof level, erect scaffold, and work through to completion before the scaffold comes down. A standard chimney rebuild in Cambridge from roof level takes two to four days on site. A full chimney rebuild in Cambridge typically costs £1,500–£3,500 depending on the height of the stack and the extent of the brickwork to be replaced.
