"I highered Bruce and his team, we're very happy with the service. They installed a couple new baseboard heaters to our existing unit to add more heat to a few rooms that's were cooler than we liked. We're very happy and much warmer. Bruce and his team were responsive and open to everything they were doing. Fast and efficient highly recommended!"

"Frank gave me a no nonsense quote within a couple hours. I hired him and he came out the next day to replace my hot water heater. He was very professional and got the job done in a couple of hours. Don’t hesitate to hire him for all your plumbing needs."

"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!"
