"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"Joe and Larry were wonderful! We bought a new house that needed work, including a serious issue with how our water heater was installed (without a pressure release valve!). Joe came by and looked at it all and because the situation was dangerous he and Larry came the very next day. Their estimate was clear and the job came in at the estimate (with one small additional nal.repair they found taking a part the toilet.). They walked me through everything and made me feel at ease. These are our new go-to plumbers!!"
