"Happy with the water heater install"

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"The workmanship was very professional and cleaned up afterwards. Wouldn't even know they were here. Billy did an excellent job with the removal and instillation of a new hot water heater. Brought the instillation up to code by adding a drip pan and expansion tank. I have them coming back to replace valves for washing machine and installing shutoff valves."

"Got an estimate for new water heater and installed the same day. Billy and his apprentice were professional and did a great job. The price was very good and I feel they really wanted to make sure we were happy with them. Would use again- thank you!"

"Bryan serviced our heater, he also told me about the condition of our heater. What it would take to repair it & that the age of the unit would make it too costly to repair. We appreciate your quality work & your advise, thank you."

"They do the exact work that they say they will do. One time shortly after they had came and worked on my plumbing, a pipe broke and they fixed it for free. I will continue to use them because I stick to who I like and trust. They have very nice employees."
