"It was a bitterly cold day in February: no hot water, no heating, and water running across the kitchen floor. After three unanswered calls to other plumbers, we tried Mayne Gas & Heating, answered on the first ring. The friendly receptionist said someone would be with us within the hour. Mark arrived promptly, introduced himself, and quickly found the source of the leak. He explained he’d need to remove part of the wall panelling, which he did so neatly we later replaced it exactly as it was. He refilled the system, bled the radiators, and tested the boiler until everything was working perfectly. Job done in two hours at a fair price. We’ll be using Mayne for all our plumbing and heating needs."
