Recommended Customer Reviews

My name is Pamela and I am leaving this review for Flat Rate Plumbing (Grand Prairie) because I know how hard it is to find truly honest, reliable, friendly and most of all professional and expertise workmanship. Roy Adams embodies what great service should resemble. He not only explains every step of his process, but is also honest about if can fix the issue or not. I am a new home owner and he also gave me honest advice about the existing cheap/ builder grade plumbing concerns but, told me not to worry about them until necessary. Most other Plumbers would have tried to have me spend a small fortune immediately. If you hire Flat Rate Plumbing, you will NOT be disappointed!! I plan to keep him servicing my home for as long as he is willing to do so.....Thank you so much Roy!!!..you are truly a gem and a blessing!!!

Reasonable, trust worthy, knowledgeable and reliable. Great communication and Roy really enjoys what he does and solves the issue. If he can't do it, he'll let you know and make local recommendations.

Roy was kind, communicative, efficient, and easy to work with from the start of our first interaction. He's an honest and knowledgeable person, who listened to my needs/concerns and fixed exactly what I needed without adding fees or trying to up sell more work. I paid exactly what he quoted me from our phone call, but made it clear before he got started that he would only do work if he believed he could make the problems better. Lucky for us he did! He was quick, got my sinks unclogged in about 20 mins, and gave me some tips on tools for new homeowners. Great service! So happy to have someone to call now :)

Roy did an amazing job repairing a slab leak that we had. He worked his butt off to find the leak and repair it. He is a very nice guy, dependable, on time, and offers a fair price. I would recommend him for any plumbing job.

Roy was quick to respond to my call and we discussed my sink problem thoroughly over the phone. He was accommodating of my work schedule when we made an appointment, and we were able to handle details via text. He quickly diagnosed the problem and the cost was much less than I expected. I will use him again for any of my plumbing needs and recommend him to my family and neighbors.

I have used flat rate plumbing on Llano for many years, and I can honestly say that I trust him in all he does. He has always been there for me when I needed him and does excellent work. He makes me feel like a friend. If you need a good plumber, you can trust in this one, Roy Adams

In need of a plumber, call Flat Rate. Awesome service, was able to let me know the problem over the phone. He was honest, on time and fixed our outside faucet with no major issue. I would recommend calling Roy for your plumbing issues. GREAT GUY!!

Very good job done by Roy! I had an issue with the outdoor faucet in my backyard that was causing a major leak and He diagnosed the problem over the phone and was able to quote me on the spot. Then when he came he quickly saw the issue and was able to replace the faucet without needing to drill into the brick work. He simply explained to us why the issue developed and how we can prevent it going forward. Couldn't have asked for better service and reasonable pricing! Will be using him in the future.

Very experienced plumber. He called, asked for history of my plumbing issue and he ACCURATELY diagnosed over the phone.
Saved me a trip and he didn't have to do that.
Really honest guy.
Would definitely use again.

Mr. Adams has made numerous repairs in my home and has always been polite and punctual. He asks questions to be sure of the problem and quickly does his work. He is clean and tidy, never leaving a mess for me to clean up after. He responds quickly and personally to service calls. I feel he charges a reasonable fee. Whenever I need a plumber, he is the one I trust.
