After being let down by a previous plumber we were so lucky to find PARAGAS. John and Steve arrived on time and power flushed the system to get rid of the blockage, installed new pipe work, pump, flu and new boiler. They were very polite, clean and tidy and removed all rubbish. Would have no hesitation in recommending PARAGAS to anyone looking for a heating engineer. Thanks guys. 5 stars all the way!
