"Harri Jones is a true expert at his job as chimney sweep, so professional in each and every way. He’s so precise at everything and no task too much, such as replacing fire rope on multi fuel stove and so clean, no soot, dust and no mess. Also so courteous and so respectful of his customers. Highly recommended, unbeatable and I would 100% definitely give him 100* if it was possible. Best luck to Harri with his business which he has taken over from Tom Jones, his late grandfather."

Popular Questions

Harri has completed a rigorous training course and successfully passed a full assessment to become a NACS (National Association of Chimney Sweeps) Member. He holds valid insurance for chimney sweeping, in line with the NACS Code of Conduct, and uses professional-grade equipment which is inspected during his assessment and regularly upgraded to the highest standards.

Harri is highly trained in dust prevention and takes great care to minimise mess. In most cases, the sweeping process is clean and controlled. However, exceptional circumstances—such as a blocked flue due to a bird’s nest—can make it difficult to guarantee no dust or debris will escape.

Ensure there is a clear path to the chimney and sufficient space to work. Harri may ask you to remove ornaments from the hearth and mantelpiece, and to clear the grate of any ash, fuel, or debris. He will bring protective dust sheets for your carpets, flooring, and furniture.

Yes. Even though these fuels don’t usually produce soot, blockages and other issues can still occur. Sweeping helps maintain proper function, prevents chimney fires, and reduces the risk of carbon monoxide poisoning.

The cost varies depending on the type of appliance or chimney and the time required to complete the job properly. Please contact Harri directly for an accurate quote.

Harri usually shows the brush emerging from the chimney pot to demonstrate that the flue has been thoroughly swept from bottom to top.

Yes. If you’re unsure when the chimney was last professionally swept, it’s important to have it cleaned for safety and peace of mind.

This depends on your appliance. Where no specific fuel is required, properly seasoned wood is a popular choice—it’s clean, efficient, and carbon neutral. Some people prefer coal, in which case we recommend buying from a local, approved coal merchant for expert guidance. Always consider local smoke-free zone regulations when choosing fuel.

If soot remains in a chimney that’s sealed, it can become damp and form an acidic black residue. In older chimneys, this can soak into the internal walls and cause severe staining or damage. Sweeping beforehand helps prevent these issues.

Smoke stains may indicate that fumes are leaking back into the room. This can be a sign of a serious issue—contact Harri for advice and an inspection as soon as possible.

Harri can recommend and install a suitable bird guard or terminal for your chimney to prevent future intrusions.

Absolutely. As a NACS-certified sweep, Harri follows a strict code of practice, maintains up-to-date equipment, and carries full public liability insurance for all chimney sweeping services.
