I definitely recommend to consult with Kevin . He fixed my shower leak few months ago . It was difficult to find where the leakage was. He was very patient and professional. The price is very reasonable. I am glad that I found good plumbing service near my house

Friendly, personable, professional. The guys were competent, efficient, and worked fast. They handled requests with the greatest of ease and had great suggestions for when I didn't know exactly what I wanted. This was a last minute installation of an electric water heater. They praised my purchases on the water heater as well as the supplementary attachments that I purchased and installed them as well. The only thing they didn't handle was the electric portion of the job, which is understandable, they are plumbers not electricians. They did have a recommendation on a sparky, whom I hired

I had a possible leak in my sprinkler system and wanted to get a second opinion. Kevin came over and was very efficient in isolating any possible problems. Turns out that my system was fine no leaks but Kevin took his time and investigated all possibilities. He checked all of my toilets checked the sprinkler valve and he checked the auto pool fill valve. I was very impressed with his knowledge and the fact that he did as much as he did at no charge. It's just as they said on the website that they will give you a professional Consultation at no charge. he didn't have to pull out the

Kevin, hope you are ok. Can't find you.
It is our second time we had to call Kevin and ask for his help. Previously, we had a leak between the walls. Kevin came on Saturday, found the problem, removed a minimum area of drywall and replace a length of the pipe. Fast, efficient and reasonably priced. Today, while we were out of town, another pipe between the walls leaked badly. Kevin came in late in the day, after hours, found the problem, replaced the leaking elbow and charged us very reasonable price again. Very responsive, professional and with a pleasant personality. We will never use anyone

Review is for phone consultation & customer service.

I reached out to Kevin regarding a malfunctioning water heater. He walked me through what to look for, reviewed my photos, offered suggestions, and advised me on next steps (e.g. what to ask the manufacturer).

Even though we decided to go directly with the manufacturer's partner technician (their parts aren't widely available), Kevin was kind and generous with his time & advice both over the phone and via text (even though it was clear that we may not be using his services), which I think speaks to him as a person and the

While others required a payment for leak detection, Kevin did not. Kevin did a great job with the staff in repairing my slab leaks. As soon as he found out that there was a second leak in the house he brought additional staff and finished the repair in the same day. His service was professional and he came well equipped with many professional tools. Required parts where in his truck so he didn't have to go back and forth from the hardware store. His service was also very affordable. I would highly recommend him if you want your repair done well and in a timely manner.

I noticed water coming out of my floors and figured I probably had a slab leak. After searching on Yelp, I came across KP Plumbing, and boy am I glad that I did. I also called a few other leak detection companies to compare prices, and Kevin offered the best price which made my decision that much easier.

Kevin was very helpful over the phone and was able to come the next day to investigate my issue. Although my leak was one of the most difficult that Kevin had come across, he was able to get the leak fixed in a timely manner, and clearly explained all of my options. He committed to the price he

Had a company with a 49.99 dollar promo come out to unclog a kitchen drain. They "tried" to snake it, and ended up quoting me 1800 to hydroscale the drain. Can anyone say scam?? I figured I give Kevin a call since he previously replaced the water pressure regulator and some piping.
This guy is the real deal! Showed up on time again, snaked the drain, and immediately, it was unclogged. No BS, no upcharging, and didn't waste any time.

No longer falling for the promo deals, just call Kevin!

We hired Kevin and his crew to relocate our washer & dryer to the garage. The crew of 5 showed up on time and were very professional. The work they performed included tying in the washer drain line to the main drain with a cleanout, adding a vent for the washer drain, tying in water lines for the washer, tying in the gas line for the dryer, and adding the dryer vent location. Kevin, Joe, & Daniel and their sons awesome. They did everything we discussed ahead of time & did quality work. Couldnt be happier, and will def use them again in the future.

Stop right there! If you're looking for a plumber call Kevin. He is a trustworthy man! After multiple attempts to clear a clog in the bath/shower I called Kevin. I described to Kevin my situation and he understood everything clearly and gave me a few tips and pointers over the phone to get the job done myself! He spent time to explain the directions to me and saved me money. Call Kevin as your trustworthy plumber

Kevin and his team put about 200 feet of gas line down at our house in two days. Everything runs great now. Kevin's a knowledgeable plumber that you can trust. He's also a really great person. I would highly recommend him.

Everyone from KP Plumbing who has come out to my father's home to help with the plumbing issues we've had has been fantastic. They were quick to diagnose the problems and easily fixed them with minimal fuss and disruption for us. Their pricing is fantastic and we really love being able to use KP Plumbing. We've been burned in the past from different plumbers so finding KP was a godsend! I highly recommend them for their amazing attitude and flawless work!

There was a leak developing under my carpet, so I called in a homeowner’s claim and was directed to find a plumber to stop or find the origin of the leak. I communicated with the owner, Kevin, who was very responsive.
Due to scheduling Kevin and I were unable to coordinate for about a day, but he was available prior to that.
When he came out and assessed the location of the air conditioner in relation to the leak, he was able to diagnose the problem. Not only did he diagnose the issue correctly (leak has dried up), but he also rectified the problem at no cost.
I appreciate that Kevin could

Kevin is the one plumber you need. I have worked with many plumbers in the past but I would highly recommend Kevin above everybody else. His rate is reasonable. He's very courteous. And his work is excellent. I am glad after all these years finally I have been able to find the one plumber that I can trust. I just wish I had found Kevin much earlier.
