Redundant chimney stacks that are deteriorating above the roofline are a liability — they can shed masonry and let water into the roof structure. We take down unused chimney stacks, make good the roof covering, and cap and seal the flue internally, leaving a tidy, weathertight finish. We cover Ely and the surrounding villages.

Many homes in Ely have chimney stacks that haven't been used since gas central heating was installed and are now simply a maintenance liability. When a redundant stack starts to lose bricks, lean or leak at the flashings, the most practical and cost-effective solution is often to take it down to just below roof level and make good the roof covering over the top.
The work involves erecting scaffold to the chimney, taking the stack down brick by brick to just below the ceiling joist level inside the roof space, capping the flue with a ventilated terminal or sealing it with a half-brick and airbrick combination to prevent condensation build-up inside the flue. Where the stack passed through the roof, we cut and fit new slates or tiles to match the existing roof covering, and re-lead the junction where the old flashings were. The result is a clean, flush roofline with no visible remnant at the top.
Removing a chimney stack can seem straightforward, but there's a significant amount of heavy masonry coming down from height. The debris has to be lowered safely — not simply dropped — and the hole left in the roof structure needs proper timber noggins fitting before the new covering goes on. Doing this without the right access and structural preparation risks tile damage, debris falling through the ceiling, and a leak within the first winter.
We'll visit and confirm whether the stack is structural (some chimneys support a party wall) before any work starts. If there's any structural consideration, we'll advise you to get a structural engineer's sign-off first. The job typically takes one to two days including scaffold.
Chimney take-down in Ely typically costs between £800 and £2,000, depending on the stack height, roof covering type and whether brickwork needs to be lowered by hand through the roof space.
