"I had Rob install a tankless hot water heater, whole house water filter, and run a new gas line for my gas stove conversion. He was very professional and and was quick to set an appointment. The whole job took a single day and he even removed and disposed of the old outdated appliances. Quality work at reasonable prices! Would highly recommend."

"Tim Clukey (Plumbing, Heating, Cooling) removed my old hot water heater and installed a new one and expansion tank in my basement. Tim did an excellent job! I had received a number of quotes from other plumbers to do this project. After speaking with the other plumbers I didn't feel comfortable hiring them and their quotes were very high. Also, they did not break down the items in their estimates. Tim had contacted me right away and we communicated several times regarding my project. Tim promptly returned my calls, provided me with an itemized estimate (very reasonable), and researched a device I was interested in adding onto my hot water heater. My project proceeded exactly like Tim said it would; the hot water tank and parts were dropped off at my house, Tim arrived on time, the electrician Tim contracted arrived on time, and Tim finished on time. Everything went like clockwork, and Tim took the time to explain what he was doing as he was installing the hot water heater. Tim also provided some sound advice regarding other plumbing matters. I will definitely hire Tim again. I found my plumber for my future projects."
