  • Boiler losing system pressure all the time

    Hired Dan to sort out the pressure problem for my boiler (boiler kept losing pressure). Dan turned up on time, he was very professional and knowledgeable. He used a very creative and cost effective way to find out where the problem was. He also left the place very clean and tidy after finishing the job. Very reasonable price, would definitely recommend!
