NACS Certified · Fully Insured · North East England
NACS-registered. Fully insured. No mess, no upsell. Every sweep ends with a smoke test and your insurer-recognised safety certificate emailed before we leave.
An annual sweep keeps your chimney drawing properly and your family safe from chimney fires and carbon monoxide. Most insurers require a current certificate — ours lands the same day.
Why sweep
It depends on what you burn. The schedule below is the NACS guidance every UK insurer expects you to follow.
Soot isn’t the only thing worth getting out of a chimney.
What happens between sweeps
Drag the slider. Soot crawls in, draw drops, risk climbs. The case for an annual sweep, made visible.
What we do
Sweeping, CCTV inspections and bird nest removal across the North East. Carried out properly, documented thoroughly, finished tidily.
Power sweep, smoke test, certificate emailed before we leave. Dust sheets, sealed vacuum — your hearth untouched.
HD video survey of the full flue. Catches cracked liners, blockages and structural wear — you keep the footage.
Blocked flues push smoke and CO into the room. We remove inactive nests safely — sweep, cap and certificate, one visit.
