My name is Ray Bridgman and I am Sootbusters Dorset. I offer a professional service to sweep all types of chimney. I use Rodtech power equipment, see here for the benefits and details of using this equipment. I pride myself on leaving your house as clean or cleaner than when I arrive. I am fully insured and can produce certification if required, give me a call. If you require a proof of sweeping certificate to satisfy your insurance company I am able to provide these after my sweep.
