You need have no concerns that Rapid Repair Drain Care is a fly-by-night operation! Simon, whose business it is, is very knowledgeable and skilled. He spent more than the two hours he charged me, not only cleaning the blocked drain, which he did within the first hour but then, at my request, inspected all the other drains. He didn't mind me hovering over him all the time he was working and he showed me what his camera was revealing, which included the tree roots that had started to enter the pipework! I can unreservedly recommend him.
