My mother-in-law (97) and her carer had a major water leak into her (my mother-in-law's) bedroom. We were in Oxford, she is in Wendover. We phoned the traders from your recommended list and the first that was immediately available was Wayne. He attended within an hour and fixed the immediate problem, to stop the leak, and then worked diligently with a colleague over the next 24 hours, including late into the night, to solve the core problem which was an internally split hot water cylinder. The system had originally been poorly designed to not facilitate easy maintenance and so Wayne fitter some further stop-cocks and a drain outlet to allow future easy draining of the system. He was professional, courteous, clean and tidy and did not try to take advantage of us in terms of emergency pricing. We will definitely now consider him to be our preferred plumber for any future work.
