Chimney Rebuilds

Chimney Rebuilds in your area

Chimney stacks take a battering from wind, rain, and frost year-round. Over time, the mortar between the bricks erodes, brickwork spalls and cracks, and the flaunching — the mortar bed that holds the pots — breaks away. On older properties in Thetford, particularly Victorian terraces and pre-war semis, it's common to find stacks that have been patched repeatedly until they reach a point where a full rebuild is the only sensible option.

A chimney rebuild involves carefully taking the stack down to a stable course of brickwork, usually just above the roofline, and rebuilding it from that point using matching or sympathetic bricks. We re-lay all courses in fresh mortar, reset the flue liners where needed, bed new chimney pots in a fresh flaunching, and install new lead flashings around the base of the stack. If the stack is no longer used for an active flue, we can cap the pots and ventilate the flue correctly to prevent damp inside the chimney breast.

Working on a chimney stack requires scaffold or a properly rated access platform — not just a ladder leaned against the roof. The weight and height of chimney work means mistakes can cause serious injury or structural damage to the roof below. A rebuilt chimney also needs to comply with current guidance on flue ventilation, particularly if the fireplace is still in use.

We scaffold the area to give us safe, stable access and protect your roof and garden from falling material. Most chimney rebuilds take two to three days depending on the height of the stack and the extent of the work. We photograph the stack before, during, and after for your records.

A full chimney stack rebuild in Thetford typically costs £1,200–£2,500, depending on the height of the stack and whether new flue liners are required.
