"Great communication throughout the entire process, informative friendly people from the office to the field. All safety precautions were taken during both the in home estimate and final installation of the water heater which was completed in under 4 hours. SeaTown are my new best friends!"

"Bel Red is a good company, but their rates are high. We had a water leak in the wall that was difficult to locate. The repair person was very helpful in locating the leak, but the bid was very high for the fix. If I had a major plumbing job I might consider the company based on their customer service."

"Jordan came out and was very friendly and knowledgeable about my leaky waterheater. He took time to explain why it was leaking and advised me on how to keep the new one maintained. Jordan was very cautious and made sure his mask was on. I really appreciated that! He did an excellent job in installing a new one and made sure things were cleaned up when done. I would refer About Plumbing to anyone and will use them again when needed."

"Ian came to our trailer park home at Black Mountain ranch. He did some painting/repair work to our deck and front gates. He was very efficient, meticulous with his workmanship, and had excellent communication with us throughout the project. He was happy to take on this small job for us and I would highly recommend their services. We were very satisfied with the outcome."

"Milo was very friendly and accommodating. I hired him to do annual maintenance on my tankless water system as well as flush it out. He discovered that the pump run constantly and that shouldn’t be happening. The result is my house is always 80° if I keep it plugged in so I always keep it unplugged. He diagnosed that the pump needs to be replaced but wasn’t absolutely positive if that would solve my heating problem. He’s supposed to be getting me a bid on replacing the pump, but I haven’t heard back from him. I would probably hire him again."

"From the free bid, to the actual install, I couldn't have asked for a more professional team - including the girls in the office (who were always friendly and kind). This is an A+ operation and I would highly recommend them to anyone looking for a repair or installation."

"They responded quickly. Big props for being able and willing to provide an accurate estimate and all the details based on pictures and over the phone. Other service providers I was considering would not give me the exact model of the heater they would install (?!?), or try to charge for a visit to give any estimate, or would change their estimate four times (!?!). Once I ok-ed the project, they were able to squeeze me in on the same day with no extra cost, did their job very quickly and without any issues, fixed another small related issue (the expansion tank was originally installed on the wrong side), and cleaned up well."
