Report
We had a great experience. Toilet had been leaking so I decided to play plumber. Then realized I need to stick to my day job. McMahon came and tried to help BUT the toilet needed replacing. They were VERY RESPONSIVE. Came back the next day and installed a new toilet. They carefully explained all the costs up front. Plus gave us a 1/2 hour heads up on arrival. Will definitely use again.

A leaky toilet! MacMahon was able to schedule me quickly for an appointment the next business day. The plumber arrived on time and had everything ship shape in less than an hour. He even had the needed parts in his truck, close to hand. They've been my go to plumbing service for years. It's always quality work provided by a knowledgeable professional.
