Advantage Plumbing have always done a good job for anything I've had them do for me. I haven't really had any complaints. Recently, they installed a downstairs toilet for us. We've had them do quite a few things.
They installed a water softer and water purifiers under my sink. They replaced two toilets, replaced a leak in my basement, and also replaced an outside sprocket. So I've had them do a lot of work in the past few years. We always have good experiences, I really do trust them. I would recommend them to others.
