I had an issue with a plumbing leak. These guys were dispatched by my insurance company to diagnose the problem. Ins would pay for the diagnosis, but I'd have been responsible to pay for repairs. They came on time, were polite and friendly, listened to me explain what happened, and within less than 5 minutes diagnosed that a bolt had come loose on the toilet, which caused the leak. I called my adjuster and he agreed they didn't need to perform the extensive testing since they found the problem. They tightened the bolt and did not charge me anything. How refreshing to find such honesty. Well done. Thank you!

Very Honest business - ARS came out to give me a quote to fix my water heater - quoted me $1880 - insisted on full replacement - I went ahead and purchased a new unit at Home Depot - had James at DeMoss come by to give me a quote - said it looked like it was just a supply line - had one of his guys come out and replace for $103. This is with a new unit sitting in my garage. Took the unit back to Home Depot and I was good to go. Very prompt on their appointments - waited on ARS from 8-12 and then they showed up at 12:45 just to give it a quick look and quote $1880. James said he would be there at 10 am and pulled up at 9:55. Will definitely use these guys again.

Our hot water heater started leaking on a Tuesday night. On Wednesday morning around 8:30 I called DeMoss and James said he'd meet me at my house at 12:30 that day to give me an estimate. I rushed home from work at lunchtime and James was waiting. He took a look at it and said they could replace the heater the following day, and gave me a reasonable estimate.

The next day two gentlemen showed up ON TIME, did all the work necessary to replace the heater and bring our 1980 setup up to code (yes, our old heater was 35 years old; W00t!), including ducting, pipes, and other stuff. James called the next day, charged me exactly what he said he'd charge, and arranged for the City to come inspect it. Everything passed with flying colors.

I've been the victim of countless utility repair people who run 3-4 hours late without calling, discover unexpected costs halfway through a job, and leave the site a mess when they're done. DeMoss did what they said they would when they said they would. They communicated clearly and respected my time so that I missed as little work as possible. Full marks.

DeMoss Plumbing is the absolute worst company I have ever dealt with. I cannot think of one portion of my massive plumbing replacement that went smoothly

First of all, I would have never chosen DeMoss if it wasn't for Chubb Insurance tying my hands behind my back and pushing me towards DeMoss due to the low-cost nature of their bid.

DeMoss was tasked with replacing old Orangeburg piping underneath my house with PVC pipe. The project was to begin in Jan. 2015 and take 6-8 weeks to complete. The project finally was completed April 17th, when I had a drop dead date of March 20th.

DeMoss leadership is completely inept. Their workers wouldn't come when they said they would, excuse after excuse was relayed to me, management would never apologize for continued delays and lies. David DeMoss and project manager Michael are the worst leaders and operators I have ever met, I honestly thought at times they were purposely trying to screw things up and then not apologize to anger me more.

If you consider DeMoss for any size of project you are making a huge mistake.

DeMoss Plumbing was absolutely horrible. I had them come out to install four bathroom faucets. I also asked them to tighten a loose faucet handle in my half bath. The guys that came out said it would take 1 1/2 hours to install the faucets and about $100 in parts. Four hours later they were still there installing faucets. As it turns out they were replacing all the copper lines under each sink. They were also replacing the drains which asked them not to do. Then to top it off, they also replaced the copper pipes in my half bath where I asked them only to tighten the faucet handle. Finally, all of their work scratched up my newly refinished counter tops. I later found out that copper piping is worth a lot of money and I suspect that they were simply trying to make money off me.

When I called the owner, Mr. DeMoss, who was the only person I was allowed to talk to, he talked over me and raised his voice when I tried to tell him that his guys scratched up my counters. He ended up coming to my house the next morning to assess the damage and he agreed to have it fixed, which he did.

Later when I got my bill in the mail I called to clarify the amount because I was confused. Again I had to talk to Mr. DeMoss who was very rude, curt and sounded completely annoyed that he had to talk to me about my bill. Again he raised his voice while I was asking questions. I hung up on him and paid my bill in full just so I did not have to deal with them anymore. Terrible experience.

After 2 other plumbers had been out to diagnose the origin of a water leak that was showing up in high water bills and could not find it, Demoss Plumbing was recommended. They sent out Johnny, who immediately went through a trouble shooting algorithm and found the leak under ground in my irrigation system. After replacing a section of the underground pipe, they fixed it!!! What a relief for me after worrying about pipes under the slab, drilling holes in walls and floors, etc., etc. I found everyone there, from Dana and James on the phone to Johnnie and Valentine on the site, to be very professional, polite and reassuring as they carefully explained what they were doing and answered my questions. You can bet that if I have any more plumbing problems, I'll call DeMoss! And....I recommend that you do too.

After having another (national) company come in and tear up our house seeking to find the source of a water leak, claiming we needed a re-route of pipes through the attic, etc., we called De Moss (based on a recommendation from a friend) for a second opinion. Their operations manager came and performed a thorough review of the situation and identified a possible leak in the washing machine, which ended up to be the correct diagnosis. He also explained the proper procedure for determining leaks in the water system, which made us realize that the other company's plumbers didn't know what they were doing, or else, attempting to gouge us for a bunch of unnecessary work. We then hired the DeMoss plumbers to rectify all the damage caused by the other company. We were very, very satisfied with this company.

DeMoss Plumbing is the best company I have ever used. I had a large water leak under my house. Another leak detection company was sent out on the advice of my management company and I was told that I had 2 leaks-one large one under my garage slab and the other under my washer and dryer. I was told the cost to fix it would be several thousand dollars. I decided on a second opinion and I'm sure glad I did. I had heard of DeMoss through a friend and had them come out and take a look. I had the pleasure of meeting Eric Kuehn and his assistant. They did a thorough leak detection and found the true leak and had it fixed in a couple of hours. It was nowhere near the slab or my appliances, but a leaking connector in my water line near the meter. My water meter is now at rest and the bill was incredibly reasonable. Thanks again to Eric for outstanding service and I would recommend DeMoss Plumbing in a heartbeat.

I had been having major issues with my toilet. It would run constantly, and then I discovered a large leak coming from the back of the toilet. (yuck-water everywhere!) I called DeMoss Plumbing and they scheduled an appointment promptly. Once they arrived, the plumbers got right to work. I was very pleased that they worked so quickly (saved me $$!) and were able to repair my issue. Afterwards, they explained the parts that were warped and needed replacing (and showed me) and explained what they did. I felt that they were extremely professional. Overall, I am very impressed with the service and now have a working toilet! (YAY!) I have spent much more at other plumbing companies and feel that DeMoss Plumbing is a company I can call in the future and TRUST.

My water meter needle was spinning like crazy so I knew it had to be a broken pipe within the foundation of our home. Sure enough, our water bill confirmed triple the normal usage. I called Fox Plumbing buy they don't do home foundation leak detection work but they did recommend DeMoss Plumbing.
I called David DeMoss to explain the problem. He reassured me that his company can fix most foundation leaks without breaking up the foundation. He said they isolate the leak, cut the pipe and reroute it through the attic. Dana cheerfully scheduled master plumbing technician Eric Kuehn to do the work.
Not being able to find feedback on DeMoss Plumbing online had me concerned but soon after Eric arrived, my concerns were gone. He patiently answered our many questions and carefully checked the routing of our water pipes. His many years of plumbing leak detection work paid off. He was able to quicly isloate the broken pipe in our foundation and carefully cut through the wall to complete the re-pipe job. And my wife especially appreciated the fact that Eric and his team wore floor protective covering on their shoes, laid protective paper on our wooden floors and cleaned up thoroughly after making the plumbing repairs.
Our insurance company received all the required paper work in perfect order and quickly paid for the repairs.
Again, special thanks to Eric Kuehn for the outstanding customer service and skillful repair of our home.
