"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"Thank you HomeAdvisor! I spoke with them late on a Saturday and by Monday afternoon my new hot water heater was installed. They shopped around to get me the best price on the equipment I needed and were so kind to keep me informed as to their arrival time. They did a fantastic job getting out the old and installing the new, I am super happy!!! I would definitely recommend them! Thank you Mike and Todd!!!"

"I hired Jason on friends recommendation to redo master bathroom. It was during covid. Incredible job! He was on time every day, immaculately clean, went extra to get things from store so I wouldn't have to, knowledgeable n professional. I then had him do a partial redo on half bath. Have used him for leaks, clogs, drippy toilet, installing grab bars. I highly recommend him. I trust him. He is efficient, clean, knowledgeable, respectful, professional. I would never use anyone else. When he commits, he is there and on time. You will never find anyone better! Carol B"

"Kenny did an excellent job and I give him 5 stars. I was told by the office staff that the installation of the new water heater (under lifetime warranty but only five years old when it needed replacing) would take up to six hours. The actual work time was closer to two and a half hours, most of the time was taken up waiting for the delivery of the new heater as well as half-way through Kenny left for another two hours, maybe even longer, to pick up an expansion tank. I had been quoted a price of $950 for the installation . After the installation the office called to ask how I wanted to pay I challenged this amount and ended up paying $850 instead. - I very much appreciated that Quinns were able and did install the hot water heater so quickly but felt I was taken advantage of financially."

"He was very knowledgeable and gave me some advice on how to avoid future problems. He was also on time and the service was done fairly quickly. He took the time to make sure all repair needed was done correctly and assured me if any problems were to occur he would be back to fix."
