"DP Plumbing and his crew went above and beyond to make sure that this job was done correctly and for the most reasonable price possible. They were professional efficient and got the job done as quickly as possible. I would highly recommend this company to my friends and family and to anyone else who wants a fair price and a professional team working at your home. I had other people come out and give me bids and none of them gave me the Comfort level that this company did. I just trusted them. I am actually having some other work done and have their card because I'm going to give them a call back for sure."

"Did a fine job installing water heater, but then the installer apparently did not push out the air in the lines through the house. The faucet in the kitchen then loss water pressure since there was debris from the old water heater in the lines. I was told there would be no charge when they came back to investigate for the inspection fee, but there was. I made my case and then it went away. Overall, they did a great job with the work. Ted and Glen are the ones I would want back. Very experienced at the trade."
