HETAS Certified · Fully Insured · North East England
Black Diamond is a fully insured, HETAS-registered chimney sweep service covering Newcastle, Sunderland, Durham, Gateshead and the wider North East. Every sweep finishes with a dust-free hearth, a smoke evacuation test, and your insurer-recognised safety certificate emailed before we leave the drive.
An annual chimney sweep keeps your chimney drawing properly, your wood burner running cleanly, and your family safe from chimney fires and carbon monoxide. Most home insurance policies require a current sweep certificate — ours arrives the same day.
What happens between sweeps
Drag the slider — soot crawls in, draw drops, risk climbs. The quiet, visible case for an annual chimney sweep.
What we do
Certified chimney sweeping, stove servicing and CCTV inspections across Newcastle, Sunderland and the wider North East — carried out properly, documented thoroughly, finished tidily.
A thorough power sweep, finished with a smoke test and your safety certificate. Dust sheets down, vacuum-sealed extraction, your hearth left exactly as we found it — only cleaner.
High-definition video survey of the full chimney. We catch cracked liners, bird nests, blockages and structural wear — and you get the footage to keep.
Annual service for log burners and multi-fuel stoves. Rope seals, fire bricks, glass gaskets, baffle plates — checked, replaced, restored to performance. Essential to keep your stove safe and efficient.
