“First time customer. My wife and I have had contractors in our home many times through the years, but we have never had a contractor leave it as clean as we did after Tom’s installation of some shower fixtures in our upstairs bathroom. His workmanship was great. It was a delight having him working in our home.”
“The technician did an excellent job installing two toilets. The parts and labor were reasonable priced. This is the second time we used Mervin Zimmerman Plumbing Heating & AC for bathroom updating and they did great work on both occasions.”
