"Larry has been my plumber for approx. 10 years. He has replaced my water heater, repaired the gas line on my stove and most recently did a complete bathroom remodel. He is reliable, trustworthy, very professional, and always on time. I will be having him remodel my second bathroom soon. I highly recommend Larry for your plumbing needs."
