"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."

"Tom called promptly after I posted the project at 7PM Monday night. By Tuesday at 3PM I had a new water heater installed and working, and at a good price. Very professional. They arrived early and there were no (bad) surprises."

"Michael knew that the part that had failed on my hot water heater was covered by a five year warranty. He contacted the manufacturer representative directly and saved me a lot of money. His work was excellent."

"Chris Sheppard is a very knowledgeable, go-to technician. His estimates are fair and his work level is top drawer ! He installed 3 new valves and removed and installed a new toilet for me. In the process he uncovered that I had a cracked flange which he suspected was causing a bad ungoing leak through my ceiling. I would highly recommend Chris to anyone looking for a great plumber at a reasonable rate. Thanks Chris !!! ⭐⭐⭐⭐⭐"

"I was thoroughly pleased with the installation of my new kitchen faucet. What I liked is that they went above and beyond. There were other things in the house that needed attention and Kyle changed did a "wellness" check around the house, the bathrooms and found that the faucet to the outside of the house needed updating. I wills say that their price was a little high but for my peace of mind, it was worth it. Within 5 days of my work being done, I recommended them to a co-worker who needed a hot water heater repaired and they are satisfied with that work too. Yes, I will call on InstaPlumbing again."
