"Water heater problem solved. Price seemed fair too. Only issue was getting receipt emailed to me which required my follow up, but no big deal. Main thing is they knew how to diagnose and then solve issues and I am confident repair is correct."

"They did a good job and the workers were great the only issue i have is they didnt install a water shut off even though i had one in the old system and i wasn’t told the price i was given to do the job didnt include one until the end of the job i would have paid extra for it i had to change a water filter since the job was done and i have to go to the street to turn off the water if i have a busted line in winter and the box is covered in ice and snow how will i get the water off this is my only gripe about the work no full disclosure i was in a rush to get it fixed it was leaking bad they should disclosed that when the estimate was done its made me rethink using them in the future"
