"My water heater stopped working some time in the middle of the night. When I woke up to take a shower there was no hot water and I was very frustrated. I called KNMP and talked to Kevin Nava. He was very easy to talk to on the phone and got to my house within a half hour. I thought I was going to spend a fortune on replacing my water heater but Kevin was able to fix the problem. The fix was low cost and done right. I have not had a problem ever since. KNMP is very professional Company and I will be going to them with any of my plumbing issues from here on out."

"Roberto and his team did an outstanding job today at my mother's home; from his initial reply throughout the entire process he was awesome. They removed her old boiler and replaced it with a new one; he even cleaned the entire surrounding area that had suffered from previous attempts to soak up the oil and/or water leakage. They ensured everything was working well. Mom has heat and hot water again and is very, very happy! Roberto even fixed the door leading from the garage into her home- WOW! Mom and I wanted to cry because of his generosity and kindness. Roberto totally went above and beyond and provided us with an overall exceptional customer service experience. We are extremely satisfied, and I highly recommend Roberto and will definitely use his services again in the future; the timeliness, value and quality of work, cleanliness and professionalism are all outstanding. He showed up on time and even finished a little earlier than promised which was very nice because it was cold in the home. Thank you, again, Roberto!"
