Fast, helpful, quality work.
My water heater control unit decided to give up on life Wednesday morning. I called Ray, he came over and checked it out just a few hours later.
After determining that it was in fact the control unit, Ray took the time to research whether anyone made a compatible unit (the original maker is out of business, and the tank is 10+ years old) and gave me reasonable options.
I ended up going with a Rinnai tankless system, which Ray got installed on Friday, 48 hours after my initial call.

Ray is very responsive to phone calls and emails, and I knew on the day that he came by to give us an estimate on installing new gas piping and a gas range that it would be a pleasure doing business with him.
Ray and his son are fast, efficient, and their quality is second to none. When they checked out our basement to plan the work for gas piping, they were quick to spot our leaking electric water tank, which I had planned on replacing with a tankless gas-powered water heater sometime in the future. In a down-to-earth, non-salesy way, Ray helped me understand the life expectancy of an already

Ray DeFosses installed the plumbing for our new home (over a year ago). We've contacted Ray several times with questions and minor issues. Ray has always been very responsive, professional, and very friendly. Recently, we had a frozen drainage line from our humidifier and weren't sure if it was a plumbing problem or an HVAC problem. We left a message with Ray and our HVAC contractor, and although Ray knew it was an HVAC issue from our description, he contacted us immediately. Ray provided a simple yet comprehensive solution for eliminating scale buildup within plumbing lines and fixtures. Ray rates
