"Cornell made sure someone would be there same day to repair even with a full schedule and delivered on the promise. Extremely pleased with the work performed by Steven. Offered to repair or replace. We chose to replace based on his straightforward explanation of each option. He replaced same day and it was a lot of hard work. Steven was friendly and professional. Great work. I definitely would recommend and use again."
Pipe was completely packed! Drain cleaning was not going to do the  job here!

"My 15 year old water heater started leaking and causing my carbon monoxide detector to go off. I decided to just get a new one since it was on its last legs anyway. The first plumbing service I called couldn't fit me in until the following afternoon, so I called Plumb-It instead. Scott quoted me some prices and said he could be there the same afternoon, and in fact, he arrived a little early, which was great. Everything took about 2 hours, the new water heater has been great, and my CO detector has been silent. Definitely would hire again."

"I called Top Tec Oct 4 to check my existing water heater. Steve came out and looked it over and gave me the bad news. My 9 year old water heater was shot. The next day, Steve removed my old water heater and installed a new Rheem water heater. I could not be more pleased with how quickly the work was completed and with Steve’s expertise!"

"Four Seasons arrived earlier than window time and came out to perform the yearly maintenance on my furnace. He said Four Seasons was offering a discount for cleaning the water heater. Since I've only lived here five years and had no idea when it was last cleaned, I also had him clean out water heater. He did an excellent job on both, replaced my furnace filter, and left the area cleaned. He explained everything he did, answered all my questions and said my water heater was very dirty and should now run more efficient."

"The water heater started to leak much worse on Sunday. He called on Sunday and was able to come early Monday morning. He took me to Menards to pick out the water heater and brought it home in his truck. He installed it quickly and removed theold one."
