"They were able to assess the job with a couple of photos to recognize the old power-vent heater I had and what a replacement would cost. We discussed options, and they could upgrade me to a tankless heater for a relatively small increase. Was in and out fairly quickly and we were very satisfied with the new tankless."

"After buying a water heater at Menards and getting it home, I called Plumb-it Inc about 1:30 p.m on a Monday. I think it was Scott who answered (no recorder!) and he said he could have 2 guys out to our house within 45 minutes to install it. The job went so smooth. They did arrive within 45 minutes. The 2 guys were very knowledgeable about installing a heater. They were efficient, quiet, polite and cleaned up afterwards. They also took the old heater and the box the new heater came in. What more could we ask for? They did everything we expected."

"It couldn’t have gone better! Carl was experienced, knowledgeable and friendly. Plus, he smelled gas which is why he replaced the valve on my water heater. It was a great visit!"

"I called Dorian to replace our water heater. He came out that day and relaxed our water heater and adjusted some pipes. He was very professional and most importantly honest and reasonable with his pricing. I would highly recommend him."

"They gave me several choices for the water heater where other companies only carried one or at least did not offer others. I also appreciated the fact that they gave me a quote over the phone. They were knowledgeable about their craft and expedited the installation once I had made a decision. I also liked that I could buy the toilet myself and they quoted just the installation so I did not have to pay the mark up for the hardscape. I am changing all of my plumbing needs to this company."
