About Us

A1 Thermoline Ltd have traded for over twenty years as a chimney installation and maintenance company, making us one of the most experienced companies in the country, involved with all aspects of chimney installation, maintenance and advice.

A chimney working properly is essential for both health, efficiency and economy of any fireplace or heating appliance, which ever type of fuel is being used. Leaking and poorly maintained chimneys are deadly and in some cases can be silent killers when fumes are leaking undetected into rooms where the chimney runs through.

Maintenance should always be based on levels of usage and not just an annual or bi-annual event. Whilst DIY stores will sell sets of rods and brushes, they won't sell experience of potential chimney problems. You wouldn't attempt to service a gas boiler without being qualified, yet a chimney has the same level of severity if poorly maintained with the added risk of a chimney fire.

We can advise and offer maintenance on any chimney relating to a fireplace, stove or cooker, whether solid fuel or gas, using fully registered and time served experienced engineers. Through our trained Gas Safe engineers we also service flueless gas appliances with the same level of expertise.
