"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!"

"Atlantic Blue responded within the hour to my inquiry. They quickly came out, gave a thorough inspection and provided a quote (with options) that was the most competitive of the 3. They provided a quote that I could respond to online. They immediately initiated the permit process. They came to repair our main water line within 2 days. The fellows that came out were very friendly and really worked hard to keep me informed (as did their main office) and did the job. Which they did to my full satisfaction. Highly recommend Atlantic Blue for the quality, service, and value. A+"

"Hired BFMD for a water main break. They were quick, clean and somehow replaced 100 feet of degraded water main line without destroying my yard or driveway. They even offered interest free financing for 18 months. Glad this is behind us and yes I would recommend!"

"Pohlman responded quickly when my water heater leaked and quickly replaced it at a competitive rate. I asked for multiple quotes and they were one of the first to respond. I appreciate the work, although I would have preferred to know which water heater was being installed before they put it in."

"Fair, honest, high-quality work, great team working together. Excellent owner that went out of his way to ensure quality work…he personally came on site to quote, had Miss Utility out in a day, began work day after quote, personally conducted post-work evaluation and secured county inspection next day! His quote was half the cost of the second bid and the inside plumbing was completed by master plumber - outstanding quality. Backhoe work exceptional - even cut and replaced sidewalk and driveway eliminating plan to fill in areas with #2 stone that would require a second contractor to repair after new line was installed - required by other contractors. My first use of this firm will not be my last."
