"Michael was fantastic with fixing the hot water pipe leakage in our ensuite. It wasn't an easy job as he had to remove the vanity, cut the tile on the wall to gain access to the pipe where it snapped. He went above and beyond to fix the problem. Not only he changed the valve on hot water pipe, he proactively checked and fixed the cold water connections as well. He seemed genuine in his communications, and explained everything on the go. It was a pleasure dealing with him. My best wishes to Michael and his company."
