Nicolae was punctual, knowledgable and tidy! He tried to identify a leak (turns out the problem may be the washing machine rather than a problem with pipes). He helped rectify the washing machine. He tidied up after himself. Cannot fault him. I have already asked him to return to do other works in my home.

John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice. Other people quoted work which was over-the-top or wouldn't have solved the problem but John got right to the issue in a no-nonsense way. Quality of the work undertaken was very good, considering the age of the building and complexity. Would recommend.
