"I give Jesse a five star rating for his work. He did a great job repairing a leaking on the water supply line to my home. However, I have some comments for Allen’s Plumbing. I initially called on Monday morning and my call was answered by an answering service and I was told that I would be called by a dispatcher. But I never received a call. On Tuesday morning I called the number from an Allen’s Plumbing email and got a no longer in service message. I then called the number from the website. I was then promptly call by a dispatcher and things got on track."

"I had a 15 year old water heater that started leaking from the bottom. It was a small leak but it needed to be fixed. Tanner came out and ran some tests on the heater. Really nice guy, was courteous and respectful. Turns out the heater was leaking from the shell itself and needed to be replaced. He was able to drain and remove the old heater safely and install the new one in under 1 hour. Amazing job, he even explained to me what to look for in various service situations. 10/10 would recommend."

"The house that we live in is very old and the plumbing is a constant problem. It started with our shower leaking and none of the big name companies would touch it, saying that we need to replace the old galvanized pipes throughout the entire house, which of course we could not afford. After learning about Shayne from a neighbor, he quoted us a price that was surprisingly affordable and the repairs, which were quite extensive took only a few hours. He has since, done multiple repairs, including replacing a toilet and repairing multiple leaks. Their work is thorough, clean done in a timely manner. It’s a family run business and his wife does an excellent job of scheduling and is great at communicating and customer service. I highly recommend Shayne and his company for all of your plumbing repair needs!"
