"David does great work—I’ve used Clay Plumbing for two boiler replacement jobs; he is reliable, works quickly and efficiently, at very reasonable cost. Good to know he’s there!"

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

"They did a great job of installing and clean up. Would recommend"
