Called about a broken pipe for my washer and Kevin quickly took care of the problem with such precision and ease. These guys are very impressive with their knowledge and competence to fix our problems. Thank you for the service!

Kevin is a great guy who responded to our request for quote through Yelp. As we were in a time crunch to repair our leak, we appreciated that Kevin told us he was booked out for the next few days upfront. However, he actually had a cancellation the same day and told us right away that he'd be able to at least look at the problem and diagnose it after all!

We were so happy he showed up just before the holiday, along with his buddy in the business, who owns also owns his own plumbing company. He came equipped with his FLIR thermal camera to see if it was a running leak and took his time to explain the possible leak sources, as well as answer various plumbing questions we had around the house. It was refreshing when he told us he wouldn't be able to do the work for the next few days, but given our constraint, he had no problem handing the job over to his buddy who would be able to fit into his schedule sooner.

Now that's awesome, and both of them earned our trust and respect, and any repeat business!

About a month ago our water heater wouldn't stay on. I had to relight it more than 5 times a day. We called a few plumbers for quotes on getting it replaced and Kevin was one of them. After talking to Kevin, I knew he was the plumber to go with. He was clear, honest, professional, and reasonably priced. He was able to fit us in to his busy schedule and replace my water heater the next day! We are 100% satisfied with the service we received and would refer him to anyone who doesn't want to deal with BS and just wants the job done!

A few weeks later... my rental property also needed the water heater replaced. I contacted Kevin and he was able to get out there the next day and replace the water heater. He kept me updated on the progress and worked with my tenant with scheduling.

Kevin will definitely be the plumber I call for any plumbing issues in the future! He has made my life so much easier by helping me out of my plumbing nightmares! Thank you so much for being awesome Kevin!

I discovered a water leak under my floor in my kitchen, I called KP Plumbing based solely on the reviews I read through Yelp. He kept in touch with me by text and came out the same day which was very much appreciated! Using his leak detection equipment he was able to uncover that it wasn't a slab leak (thank goodness) and he also checked all plumbing fittings for leaks. He didn't end up doing any work for me as the source of the leak is still unknown and most likely not a plumbing issue, but he did provide valuable diagnostics and advice. For sure I'm calling him if I ever need a plumber again!

KP came to house and located slab leak. Told that cost of detection would be absorbed into total cost of repair, if selected.
Scope of work was to cut small window in wall of adjacent wet-bar for access to cold water line that will be divided, one end to be capped and the other end would be joined to Pex A tubing, routed up through wall into attic (one story house), across a horizontal distance of approximately 25', then joined to copper tubing down the outside of kitchen wall and then through wall to adjacent sink cold water line, completing the by-pass. The estimated price came in the middle of two other bids which would also include in-wall tunneling and subsequent patching (no outside copper tubing but more work and more holes in the wall).
KP was selected and arrived on appointed day with assistant and second plumber. Pulled inspection panel inside closet open to see cutout in house's slab (far from leak area), saw partially corroded drain pipe from bath tub, 'that will need fixing', a separate job (nothing to do with the original water leak). Window was cut into wall of wet-bar, cold water line isolated, cut and one end capped as planned. Assistant plumber sent to work under sink to replace and install new angle valve, while the licensed plumbers spent most of the time in discussions out of earshot. After two hours, announcement was made that 'its done'. How? Plumber's Ninja Trick!
This was how the by-pass was achieved. There is an existing copper cold water line running from the main line, outside the house, into the kitchen for drinking water filtration equipment that sat next to the sink. The plumber just replaced the angle valve, disconnect the plastic tubing from the filter and connect the cold water flex line of the faucet to the angle valve. Done. No running Pex line into the attic, no cutting holes in the wall (other than the initial one in the wet-bar), no patching, less work for the plumbers. What is there not to like?
The adjusted bill was $850. Detection $175, material $50 (angle valve and one pipe cap) and $625 labor. This was presented after completion, no information as to the change of plan or the cost before proceeding. Most people would hesitate to pay such price for the amount of work required and would likely sought other bids. Was this discussed with KP? Yes, and the answer was 'That's our price'!
Yes, KP could have gone ahead with the original repipe plan and we would have been happy to pay the estimated cost, not knowing the alternative. What is the likelihood that some knowledgeable friend would find out and informed us of it at a later date?
Should an experienced plumber not be aware of the cheaper alternative presence? Should he not want to save his customer's money and be paid fairly for the actual work or should he be more concerned with maximizing his profit at the customer's expense? These are question of ethics.
Too much weight had been given to past glowing reviews.

Not surprising response. Best defense is an offense against the victim. Original review stands.

My renter called letting me know there was a leak in the kitchen area, around the hot water heater. Not knowing of any plumbers in the area I went to Yelp and found KP Plumbing. I scored! Called KP, spoke to Kevin who was able to fit me in his schedule, same day. Water pipe inside the wall had cracked, Kevin was able to stop the leak and the next day came back to do all the necessary repairs. Kevin even came back that evening to check on his work. Both I and my renter were very pleased with Kevin's responsiveness and work.

People on my Facebook know for a week I've been stressing about a slab leak and the possibility of having my place ripped to pieces. I also feared for my neurotic cat who would freak going through such a major disruption so I got some cat tranquilizers to be prepared. The tranquilizers worked great and I was happy. As for the cat they did not do a thing. These guys were amazing. An army of people showed up. I discussed my fears of days of disruptions and holes in the ceiling and walls and possibly no water for days. I was immediately put at ease with a little information how the process works and what would be involved. High tech equipment was used plus one technique that surprised me that found the problem within minutes. Then the stunner. I was told the job would be completed in a couple of hours. When you have a slab leak it typically takes two days or more not two hours to fix. You can Google me on that. Another fear I have when calling a plumber, electrician, or contractor is from experience I've been put through the ""upsell"" treatment and once fell for it, spent thousands, and was ripped off. None of that here for the first time since owning my place. There were a couple of suggestions for the future but no selling. Fair price, very nice guys, and politely tolerated a neurotic on his third cat tranquilier until the job was completed. BTW, total time? Under two hours.

I called my Homeowners insurance to fix our leaking bathroom sink. Due to our customized French sink, the plumber said he will not he able to fix it and the insurance will not cover it. I called Kevin, he came the same day, give me an estimate and the following day, he came and fix it and was done within 30 minutes. He also fix my clogged shower for free. He is very efficient, reliable and punctual. So happy with his excellent service!

We were on vacation & once came home heard Heavy water flowing in the walls. My husband could not find the leak within the house or garage, so he shut the main water off while I tried to get a plumber out . This was a Saturday & I called (5) other plumbers that would either not call me back or tell me to make an appointment to come out. I found Kevin on Yelp & called him & he fit us in his schedule - still Saturday, & gave us a Free estimate at home . We had a busted pipe under our foundation & Kevin gave us a reasonable price & said he could fix it within a day. Kevin & his team were very professional in telling us the scope of the job ie: where the holes would have to go in the walls to replace the leaky pipes. He was able to repair & replace our water piping thru the attic, so we did not have to tear up my floors. I will always recommend him to my family & friends- the other
5 star reviews are correct. He is a Trustworthy guy that is for sure, & you can depend on him & his team.

Kevin came to my house tonight and check to see if there is a leaking in my shower pan. He is polite, honest and knows his work very well. He found out there is no leaking in my shower pan. The tiny hole I found on the shower pan is not a leaking hole but a small chip of fiberglass. He patiently gave me good advices even though I don't need to pay him a repair fee. Thanks Kevin for your help and expertise. No wonder you earned all 5 star reviews!
