Tankless Water Heater Installation and Repair

I’ve used Jason a couple of times for plumbing services and he does great work. Prompt, courteous, clean and he solved the issue. Over the years, we had multiple plumbers look at the issue and only provided temporary fixes or elaborate replacements. His services and prices are fair for what you get in return. Highly recommend. FYI - This Review is coming from a design and construction professional. I’ve been in the industry for 25 years and can attest that it is difficult to find reputable contractors like Kings. I work/travel a ton, so I can’t take on these projects myself and have to rely on competent others. Jason fits the bill. Got a plumbing issue…Call him.

I had a problem that was caused by Home Depot which Kings Custom Plumbing promptly took care of for me. He properly installed the drain hose from my new dishwasher and made sure that it performed like it is supposed to and that there were no leaks. This is the second time that he has taken care of a plumbing issue for my home. I highly recommend him for all of your plumbing needs!

Very smart and knowledgeable guy, had the issue located and fixed in minutes. Highly recommend!

Jason is excellent—high quality work, honest, and very helpful. We highly recommend him and his work!

I called Jason on a Wednesday afternoon about our toilet and he came by Wednesday evening and quickly got our toilet fixed. He was very responsive and quick to show up. We will absolutely be using him in the future.

Great response time, efficient and knowledgeable. Provided me with options for my issue and advice for moving forward. Would definitely recommend using this service

Great experience! We had a non-emergency water heater replacement and, initially, got a quote from another local company for electric 50-gallon plus water softener system. We thought it was WAY too high and turns out we were right. King Custom Plumbing gave us the same options at literally almost 50% of the cost the other guys quoted (not even joking). When they realized we had natural gas available they also added an estimate for tankless just to let us know it was on the table but it was very low pressure. We were super surprised how much more affordable it was going to be then we thought (we were to scared to even bring it up with the other guys we got the first estimate from because we were pretty much to our max budget with the option that included the electric water tank). When we thought about the cost savings in energy, the longevity of a tankless system (Navien), along with the price, logistically it is a great investment. They did a excellent job assessing the project; installation went very well with minimal impact on to our household routines. And now, since we don't have a bulky water heater and they were able to install the treatment system in an out-of-the-way place, we also have more room in our basement, so added bonus.

The shower upgrades were quick and easy. Jason made the process painless. Highly recommend this company for any plumbing needs!

I’ve worked with Jason King on several occasions. He fully gutted/replaced 2 of my bathrooms as I was slowly renovating my older home. He works quick which is always a plus when a bathroom is out of order. I’ve also reached out to him to troubleshoot other issues randomly and he’s been helpful. It’s hard to find good help these days so and he’s always been reliable so I’ll continue to recommend him!

Jason is a master of plumbing he did such a wonderful job for us and for that I thank you very much for want you did Jason Hyon and Jimmy

The best around. Always follows up and returns calls or messages.

Jason communicated promptly about his availability, put me on the schedule and arrived when expected. He solved my issue while taking the time to explain what the problem was and why he would correct in the manner he did so that the problem would not reoccur. He also followed back up to ensure that the problem was resolved satisfactorily.

Jason was prompt for giving me and estimate..and just a quick to come back and do the job. I've already started giving out his cards. He is super nice as well.i highly recommend him.

Jason was very professional and thorough! Highly recommend Kings Custom Plumbing.

Great experience, recommend these guys

Jason is super helpful, prompt, friendly, and communicative! The hose on my pull-down faucet went bad and he was able to get it fixed in 5 minutes once we got the part from the manufacturer, which he helped me with every step of the way. He left my kitchen exactly as he found it and was consistently reachable and arrived when he said he would. I am very happy and will call him again for my plumbing needs!

Jason Is awesome he knows exactly what he is doing and explains the issue very well. I do recommend this company.

Fast, reliable service!

I could not say enough about how professional and helpful Jason was. He checked out my problem and provided different solutions so I could choose what best suited me. He called to follow up everything was ok and even came back out when I called about a different problem. He goes above and beyond

Excellent plumber. Jason has the knowledge to complete any type of plumbing job. Great prices and quality of work. Highly recommend.

I was very happy to get my hot water on and the leaks stopped. All the repairs were completed in a few hours.

I just love this man. My hot water heater died this morning and in a panic I call Mr. King to help me with a new one. He came the same day and put me in a new one. I'm so happy with the service from this nice man. He was professional, quick and cleaned up after himself.

Jason answered the phone at 7:30am He came to my rental the next morning ( Christmas Eve) to diagnose the problem. He didn’t charge anything for coming out and diagnosing. He showed up at 8 o’clock in the morning the day after Christmas, exactly as he said he would. He fixed the problem and left the place spotless. It was not a small job, but he finished it in a very timely manner. Everything about this company is top-notch and professional. Their prices are very good and in line with anyone else I have ever used. I would highly recommend this company for large or small plumbing issues

Was prompt, professional, courteous, and knows what they are doing! 10/10 recommended.

I was referred to Jason King of KCP by a long-time friend and real estate investor, and I couldn't be happier with the choice. From the start, Jason was incredibly responsive and demonstrated a high level of skill in addressing our leaking main drain pipes. He managed to fix the issue promptly, which minimized downtime for my tenant's business operations—a critical factor for us. During the repairs, he discovered more damage than we had initially anticipated; however, he honored the original estimate, which was a pleasant surprise. His pricing was very reasonable from the beginning, making the entire experience even more satisfactory. The job was completed to my full satisfaction, and I appreciate the professionalism he exhibited throughout the process. Based on my experience, I highly recommend Jason and KCP to anyone in need of reliable plumbing services.

Jason was extremely nice & down-to-earth - he fixed our situation in no time at all. He is also very reasonably priced. I definitely recommend him & would call him again if another problem should arise.

Kings is top notch!

Kings Custom Plumbing is a top-notch! Professional, reliable and fast. They fixed our issue quickly and with friendly service! Highly Recommend!

Jason is a good guy and a great plummer. He put water lines and waist lines for a 3 piece bathroom plus a washer dryer hook up. Worked around my drop ceiling down stairs so it wouldn't be easier for me to put back up. He also fixed plumbing for the previous owner so it would pass inspection. Jason was here when he said he would be. He has a great personality. His work is meticulous. Price's were much lower then other companies. I would recommend him highly

I called Mr. King, he answered the call personally, I told him of the problematic leak I had,he took my information and took care of the problem that day. The thing I like most is his concern for the problem and that he showed up for the repair when he said he would. I have learned that this sort of integrity is rare these days. As a contractor myself ,I plan to call on King's Custom Plumbing again for my plumbing needs.

Very professional and kind. Came on time, did the work in a timely fashion and cleaned up the space. I plan on hiring him again when I'm ready to install a hot water heater, definitely recommend!

JASON KING IS THE BEST.... WITH THE ATRESS OF MOVING,THING SEEMED TO BE GOIN ALL WRONG. I thought I was on deaths door......Jason was quick efficient fair and the best. Where ever my wife and I move to next....whether its st louis or down the street... Jason King will be our plumber!!!!!!!

I called Mr. King on a Saturday evening - explained my problem and sent him pictures. We set a time for 9am Sunday morning and he arrived 5 minutes early and fully prepared with everything needed. He had the water line repaired in less than 10 minutes! His price was more than reasonable - especially for an emergency and on a weekend. I highly recommend his business. He’s extremely knowledgeable and professional. He will definitely be my first call should I need plumbing assistance in the future and will recommend him to all my friends and family.

Mr King is one hell of a plumber. He had my upstairs bathroom back to normal in no time. Professional and knowledgeable, I’m in sales and honestly couldn’t ask for much better service than him. Thank you Jason.

Jason was very prompt getting to job and competed it as promised. Will definitely use him again!

Had a major to me issue on Saturday. Jason was at the house within an hour and an hour after that everything was fixed! Not only was he fast, but very reasonable. Would absolutely recommend to anyone needing service, especially after hours or on weekends.

We were very impressed and pleased with the service Jason and his staff did installing a new tub for us. Jason is very dependable, professional, and completed the project in one day. We would highly recommend Jason and Kings Custom Plumbing to others and for any future Plumbing issues we may have. Thank you, Jason and Kings Custom Plumbing!

Very prompt and great follow-through. Pleasant to work with and very efficient.

I called late at night and even though Mr. King had a busy schedule, he still managed to squeeze me in the next morning. He told me over the phone he would get my water back on, and that he did! Would highly recommend.

Jason's name was mentioned when I was asking around for a reputable local plumber. I texted him late one evening and he showed up the next morning and replaced our water heater. Very professional. Highly recommended!

Jason is an excellent plumber. He’s professional and efficient! He installed a new water heater and did a really good & clean job. We also spoke about a few other potential jobs for the future. We will definitely call KCP for our future plumbing needs.

Jason was a superhero, save the day, outstanding man to the rescue. I called him around midnight. He was there in under 10min.Didnt seem at all bothered by the time. Most 24 hour service people don’t seem as eager to help when it is late at night. He fixed the issue with right away and offered a little extra advice to help for later. Top tier service no question. Call Jason.
