"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!"

"It went very well. They were the first and only plumbers to respond to the project. It was just before the 4th of July and the appointment was made for Tuesday the 6th. I was called that morning by them to see if they could come earlier because they had finish the job before me. I said yes and they arrived 20 min ahead of time. First thing that was done was examining what I had purchased. When that was okay the old toilet was removed. The flange needed to be replaced. I had figured that since the toilet was very loose on the floor. We discussed options and possible problems with each step. I was quoted a range of cost above the quote of project. It seemed very reasonable. When it was done the low numbers of both quotes were used and I was charged $529 which word for me. All trash was removed and the area was left very clean. We were able to discuss next steps I was thinking of for that bathroom. I was giving some very good advice. Excellent work! I recommend them and I will used them again when they he time comes"

"Jeremy and his team gave me the best contractor experience I've ever had. He listened to what I wanted, provided a fair quote for a central A/C replacement (air handler and condenser), and never pressured me or tried to upsell. In passing, he mentioned a heat pump option for the shoulder months to reduce oil use, but that was it. After doing my own research, I called him back with questions, and he took the time to walk through the pros and cons honestly. There was no sales pitch, I actually asked for a quote heat pump quote too, because I saw the benefits myself. I ultimately chose the heat pump and appreciate that Jeremy gave me the information needed to make an informed decision. His crew was fantastic, friendly, professional, and thorough. They removed the old system and completed prep work on day one, then finished the install on day two and walked me through everything. Great communication, great pricing, great workmanship. I highly recommend Jeremy and his team!"
