"Well let me start by saying I called several water heater companies to inquire about an estimate for my hot water heater that was not getting real hot. He was the ONLY repair person to come out that gave me the feeling he was trying to fix my hot water heater and not trying to sale me a new hot water. I never had a hot water heater water heater issue before therefore i was not familar with pontential problems. Everbody tried to get me to buy something called elements without actually trying to fix my heater. Wallace plumbing was able to identify some pressure thing or something with the thermostat that he fixed and saved me pontially thousands of dollars that other companies tried to sales pitch me. I then called Wallace plumbing because my toliet kept running and Wallace came out and fixed my toliet in minutes and his prices are very affordable. I will be using Wallace plumbing for any future needs and I recommend them!"

"I called at 8:00pm on a Tuesday night. The plumber came before 10:00pm as promised. He replaced a leaking shut-off valve and associated pipe within an hour. Cost was as quoted for one hour labor plus parts which were less expensive than expected. No extra costs for travel time or anything else. We will definitely use again."

"I found my water heater leaking just after 9 AM. Called and was given a quote over the phone. They arrived by 11 AM and were done by 2:30. Very good service. They covered my floors with drop cloths, cleaned up nicely and hauled away the old unit. Price included the new water heater, a new shutoff, valve, fittings, drip pan and expansion tank. Professional service done very promptly at a fair price. I was extremely satisfied!"

"James did multiple jobs for me after diagnosing the actual problem. Correcting the issue required james to replace part of an old pipe which could only be accessed through a ceiling. James not only fixed the plumbing issue, he completed the carpentry work and repaired the ceiling. He also replaced my shower floor and the tiles surrounding it. James also replaced faucets on my utility sink. James is exceptionally knowledgeable, professional, and a master of his craft. I highly recommend hiring him for your plumbing needs and wants."
