"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."

"Rob Quigley was awesome. Professional, efficient and knowledgeable. Couldn’t have had a better person to install my water heater. To HL Bowman—you better hang on to this guy! He’s an asset to your company."

"I was thoroughly pleased with the installation of my new kitchen faucet. What I liked is that they went above and beyond. There were other things in the house that needed attention and Kyle changed did a "wellness" check around the house, the bathrooms and found that the faucet to the outside of the house needed updating. I wills say that their price was a little high but for my peace of mind, it was worth it. Within 5 days of my work being done, I recommended them to a co-worker who needed a hot water heater repaired and they are satisfied with that work too. Yes, I will call on InstaPlumbing again."

"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!!!"

"P&M Plumbing arrived promptly and on short notice. The work was done very professionally, area left clean and orderly and the sump pump works phenomenally! I had spent 17 hours vacuuming and lugging water after the last storm, so I was thrilled at the thought of having a sump pump. We received about 3 inches of rain the next day and they even called to make sure everything was working well! In this day, it is a wonderful surprise to have a company really care about the customer and the quality of their work and I am more than delighted. Even with the 5-6 inches we received last night, I had no cleanup to do! I am highly recommending P&M!"

"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."
