We can sweep both lined and unlined gas flues, but the gas must be disconnected and reconnected by a suitably qualified engineer. This can be arranged by contacting a ‘Gas Safe’ registered fitter. We do not disconnect or connect gas fires. After sweeping, a smoke test is carried out to ensure there is sufficient draw on the flue. We strongly recommend that a Carbon Monoxide Detector is fitted to all rooms with a gas fire, these can be purchased form DIY outlets for around £20. We also strongly recommend that a suitable cowl is fitted to the top of the chimney to prevent birds, bats and squirrels from nesting in the flue and blocking the free flow of fumes.
