Cistern repaired and new isolating valve fitted

Called Martin as we had a cistern that was overflowing, and then when I tried to turn the isolating valve, it started to drip. He agreed to come out the following day. He arrived promptly and quickly replaced the isolating valve and adjusted the cistern valve. He also cleaned some of the limescale that had built up around the cistern. He completed the job efficiently and tidily, also safely, taking into account the current COVID rules. I would have no hesitation in recommending him.
