At this busiest time in the Trade’s year, we had to be a little patient, but the result was well worth it! After Months spent fiddling about with bleed valves and air locks in our system, Harry was our choice for changeover to a sealed system, and carried out the work yesterday. Polite, kind and very knowledgeable he was also competitively priced, and I would not hesitate to recommend him to others. We will certainly recall him when the next heating system service comes round. Particularly diligent in post-work clear-up .... well done Harry & Jack, and thanks to myBuilder for facilitating the initial contact.
