An unused chimney stack that is deteriorating is an expense and a water ingress risk with no benefit. We take down redundant chimney stacks safely from scaffold, make good the roof covering, and leave the area properly weatherproofed. It's a permanent solution that removes ongoing maintenance costs.

Many Cambridge homes, particularly mid-terrace and semi-detached Victorian properties, have chimney stacks serving fireplaces that have been sealed off for decades. When these stacks start to deteriorate, they become an ongoing maintenance liability — and if a stack is not in use, there is rarely any reason to spend money rebuilding it. Taking the stack down below roof level and making good is a sensible, permanent solution.
A chimney take-down involves erecting scaffold to give safe working access. The chimney pots and flaunching are removed first, then the brickwork is carefully taken down course by course to below roof level — typically to just below the line of the slates or tiles. The internal void is capped with a concrete or mortar slab to prevent moisture tracking down. The roof covering is then made good around the former stack position: on a tiled or slated roof this means cutting new tiles or slates to fill the gap neatly. Any redundant flashing material is removed and the area is fully waterproofed. Where a party wall is shared with a neighbour, we take the stack down to the party wall and cap it level.
This is not work that can be done safely from a ladder. Dislodging brickwork at height without proper containment risks tiles being damaged and debris falling — scaffold allows controlled demolition and proper protection of the roof around the work area.
We survey the stack and roof before quoting, confirm the scope with you in writing, and complete most take-downs within two to three days including scaffold erection and striking. A chimney take-down on a standard Cambridge terrace or semi-detached property typically costs £900–£2,000 depending on the height and size of the stack.
