Chimney Sweeping Smoke Testing Pots & Cowlings Lining Services Chimney Sweeping Smoke Testing Pots & Cowlings Lining Services Smoke Testing Is your chimney safe for use?

J's Chimney Sweeps carry out a full range of chimney smoke testing services in West London, Middlesex and Surrey.


The purpose of chimney smoke testing is to establish whether or not a chimney flue is sound and fit for use and has adequate draught to ensure the safe removal of smoke and to ensure that the combustion gasses evacuate from the fireplace upwards and out through the chimney pot and not leak into any other areas which surround the chimney system.


The smoke test will identify cracks and leaks in the chimney flue which if unidentified could result in harmful gasses and Carbon Monoxide (Co) leaking into your home or that of a neighbours.


Our chimney sweeps have attended and passed the assessments necessary to allow us to issue National Association of Chimney Sweeps ( NACS ) Certificates of Chimney Smoke Testing. We are also deemed competent under the HETAS schemes to allow us to competently smoke test your chimneys for safe use when burning either solid fuel (smokeless fuel, coal & wood) or gas appliances.


The smoke testing is carried out in accordance with the relevant Building Regulations and British and European Standards. It is a requirement prior to smoke testing to first sweep the chimney to ensure that it is clear and free from soot which could block existing cracks in the chimney flue.
