Sam is great to deal with and friendly. Talks you through what is needed and quotes a very fair price. Turns up bang on time when he says. A pleasure to deal with him, and I would not hesitate to use him again.

What a hero! John arrived within an hour of our initial phone call despite it being late in the afternoon. He went above and beyond the line of duty systematically fixing not only the original posted job but others that reared their ugly heads in our old stone cottage. He would not leave for the evening (returning to repair the other problems a day later) until he was able to leave us with an electricity supply as it is needed to bring water to the house. I cannot fault any aspect of his work-top bloke too!
