Recommended Customer Reviews

We appreciate KMP and Don Lilly so much!!! They helped us and we felt a little hopeless after going back forth from plumber to electrician!!!

Had a leak at the water main, had the city come out to tell me it was on my side of the meter. So I went on Yelp looking for a plumber and came upon KMP, so I gave them a call and to make a long story short, I arranged with KMP to come out between 2 - 5 PM but would call if they got an opening. They called and showed up before noon, gave me the estimate and started to work. They had it done very quickly and efficiently even made some improvements on the connection to the sprinkler system. I appreciated their promptness and the clean condition they left the area.

I have never been so aggravated over needing a question answered Alejandro which obviously answers for several locations she repeatedly said could not answer one question is this regular business hours on the weekend? Is there a extra fee for having you come out on the weekends? These were questions that she could not answer she could not answer what kind of safety precautions we are taking because of the covid19 spread at this time you have a great day and I will not refer or call back to your business

When we saw water running down the driveway on a Saturday afternoon, we knew there was trouble. A neighbor had (a different) plumber at their home who was kind enough to come over and help us get the water shut off at the street. But his dispatch team couldn't get anyone out until Monday afternoon. I called KMP and crossed my fingers.
While Henry couldn't make it out Saturday, he was at my house at 8 am on Sunday morning. I provided the fresh coffee and he provided a best-case solution for a broken pipe --- not under my slab and not under my driveway. No jackhammers! It was in the flowerbed, but he didn't even have to dig up any of my bushes. I was fully expecting a $1500 invoice (weekend emergency service) but was pleasantly surprised. It's never a convenient time to have a plumbing issue, but Henry and KMP made a bad situation much more tolerable.

Top notch service! Received service for a leaky toilet repair. The technician was on time, repaired my toilet and treated my home with respect (not leaving any trash particles behind). I would definitely use KMP again and refer all my friends!

I called over the weekend with a leaking kitchen sink (not an emergency). I got a call back first thing Monday morning to schedule the repair. They confirmed it wasn't an emergency and fit me in first thing Tuesday morning. Donald C was amazing! He called when he was on his way and got right to work on the sink. Not only did he figure out what was wrong within a few minutes, he also took the time to explain what was broken and how he was going to fix it. Donald also went out of his way to teach me basic garbage disposal maintenance which was very much appreciated. This has been one of the most pleasant repair experiences I've ever had. He was friendly and extremely efficient. I mentioned an old toilet in my guest bathroom that had been running constantly and he didn't hesitate to take a look at it since he had some extra time. He fixed the toilet as well in about 10 minutes and again took the time to explain what was wrong and what parts he would be replacing. The price for the work and replaced parts was extremely fair and worth every penny. I would highly recommend using KMP and be sure to request Donald C!!

Called midday Saturday to have urgent repairs made to my broken water main. They arrived within an hour, charged 79 for coming out, confirmed the repairs to be made as well as the price they wanted to charge (fair and reasonable in our opinion) we agreed and the work was completed with an hour or so. Very polite no BS and trustworthy. 5 Star service. Will use for any future plumbing needs.

I am selling my house and the buyer's inspector convinced them that our water pressure was too high (86 psi & he said 80 was correct). Pressure is like money to me-the more the better!
Anyway they specified we have a pressure Reducing Valve on our side of the meter.
Donald was dispatched and he was great. He shook my hand when he introduced himself, called ahead to give me ETA and was even a little early. He located where the valve needed to be installed, dug up the yard and got everything done efficiently. He even hauled off the excess dirt & returned the sod to it's place. Donald adjusted the pressure using his gauge to 78 PSI.
I had a great experience and used an online coupon for $40. If the work had been $100 less I would add a 5th star. Plumbing is only cheap if you aren't paying the bill.

I've done business with KMP as a vendor for the company and never had any problems with them. I decided to use them as a customer and that is a different story. In August 2013 I had a problem with a leak in my front yard and was happy to call a local company to come fix the problem. They fixed the problem which did not take long at all but cost a little under 300 which seemed pretty high but I thought the problem would be done so I was okay to pay the bill. Come to now in August 2016, the same exact problem has started leaking in the same exact spot. I called KMP to see if there was a warranty or some sort of discount since they were the original Plumbing company to fix the problem. I was then met with terrible customer service by the woman who answered the phone and would go to the line "did the ground move?" and continued to not give any answers or solutions. I was then transferred to the boss who said that they back their work but was not going to warranty or discount anything for fixing the same exact problem and "good luck with trying to get a company to give you a lifetime warranty."

I am not a happy camper. Earlier this Summer, I had KMP come clean out my sewer line. While they were able to clean the roots out where another plumber couldn't, they informed me that my line was broken near the curb that they could not penetrate (they marked the spot with paint on the grass and curb) and the sewer line was going to have to be replaced from the house to the street at a cost of $4,700. What they didn't tell me and what I found out from a friend was that any breaks within 5 or so feet of the curb was the responsibility of the City, as it's within the City's right-of-way. The City of Arlington got it repaired, at NO COST TO ME, within 3 days. So, if I had just given KMP the OK to fix it, I would have had my yard torn up, a tree would have had to be removed, my mailbox would have had to been relocated, and I would have been out $4,700. Hhhhmmmm, the City of Arlington repaired it for FREE. So, why didn't KMP tell me to call the City? Surely they know the code. It appears to me they just wanted the $4,700 job!
