More about us

20 years chimney experience

Allchimneys was founded by Craig Hunter, who learned the trade from his steeplejack father at 17.

Craig, his father Roger, and his brother have worked on thousands of chimneys across the country — from domestic repairs to industrial chimney structures and heritage steeplejack projects including the gilding of weather vanes at the Tower of London.

Over 35 years of accumulated knowledge brought to every job we take on.

HETAS certified appliance installation

Our team is HETAS registered to carry out the installation of solid fuel appliances including log and wood burning stoves and associated chimney works.

Allchimneys are trained and registered with NACS (National Association of Chimney Sweeps) and provide a fully insured and certified chimney sweeping service.

What clients say

Anabela Pinto

Recently Craig and his team cleared our second chimney after year's of neglect. He explained what he was doing and gave honest opinion and options. He works closely with a gas man, which helps me get the task done. Craig has been clearing our wood burning chimney since we moved in the house in 2015. All good.

Rachel Morris

A great, friendly and expert service. Would highly recommend. From initial visit to guidance choosing a suitable new stove, to making sure all regulations were spot on. Installation was stress-free and the team kept everything so tidy taking massive consideration to keep things meat-free. Loads of information and knowledge shared and their number is already saved to come and do some more work. Over the moon with the results. Thank you.
