When John McGill founded McGill Plumbing in Hamilton, Ohio in 1932, he had one simple goal in mind: To provide the best service at the best prices. Although many things have changed throughout the years, we are still family owned and operated and our mission has remained the same. Since moving to Largo, Florida in 1964, we have prided ourselves on providing Pinellas County homes and businesses with the finest plumbing service at outstanding prices. Yeah, we can do that. McGill Plumbing and Water Treatment offers a full line of residential and commercial plumbing services. No job is too big or too small. Service is what we do. If water runs through it, we do it. Try us, we do what we promise. Remember, with McGill Plumbing your satisfaction is guaranteed.
