"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!"

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"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!"

"Matt, AJ, Scott, Vinnie, Charlie all did a terrific job. They installed a gas water heater, installed a shut off on the water heater where there was one missing, replaced a kitchen sink from an old double sink to a new full size sink and in doing so, moved the garbage disposal and re-piped the whole project. They checked other pipes & plumbing and repaired a broken outside water pipe. Tisha in the office was also wonderful - very accommodating, congenial and they are all very customer service oriented. Respectful, honest, and I would highly recommend this company to anyone."
