"These guys were amazing. I hired them to replace my tankless hot water heater. They took a no need to haggle approach to the estimate process, which I appreciated. The install process felt very white glove, with runners deployed left left my floors and freshly painted walls without a mark. JD was very professional and personable, taking the needed time to do the install correct the first time. They even went the extra mile and fixed an unrelated issue (was not their fault) that would have failed the city inspection. What service! These guys are my new go to plumbers "

"Terrific response time! Called for quote at 12:24 pm. Jim quickly evaluated my need for two 50 gallon gas water heaters. Recommended Bradford White gas water heaters to replace my 20 year old rusting water heaters. His crew of 3 arrived at 1:30 pm and by 3:30 pm new water heaters installed and old water heaters removed from 3rd story walk in attic. Very efficient and clean installation. Price exactly as quoted. If you need water heater replacement call Jim at Water Heater Pros!!!"

"I just had David install a Rinnai tankless water heater and could not be more pleased. I had two other contractors give me bids, one stated he would have to do considerably more than what David had told me and attempted to sell me another tankless heater that wasn’t as good a day an install and purchase price about $500 more. The second contractor told me to get a standard water heater since everyone he talked with that got a tankless wanted to yank it out after a month since none of tankless heaters did what they said. In other words they didn’t know how to install this “Cadillac of tankless heaters”. David was very professional and installed the Rinnai in a few hours. I’d definitely recommend him, he knows more about these tankless system since his practice concentrated on this. I’m very happy with his quality work and you will be as well"

"I recently had 100% Plumbing Houston install a tankless water heater in my home, and the entire experience was fantastic! From the initial consultation to the final installation, everything was handled professionally and efficiently. The technician walked me through the benefits of going tankless, helped me choose the right model, and explained the installation process clearly. On installation day, the team arrived on time, worked quickly, and made sure everything was set up perfectly. They were respectful of my home, cleaned up afterward, and even showed me how to operate and maintain the new system. The difference in performance is amazing?I have endless hot water and improved energy efficiency. I couldn?t be happier with the upgrade or the service I received. If you?re considering a tankless water heater, I highly recommend 100% Plumbing Houston. Great workmanship, honest pricing, and top-notch customer service!"

"Perfect. My technician was polite, professional and answered all my questions and concerns. In addition to the water heater flush, he replaced two leaky valves, showing me what the issue was and without being pushy (it may have been okay to wait, but I could see the potential issue myself). Thanks for a job well done and being so pleasant and helpful!!"

"I had a 14 year old water in my attic and after the pilot lite went out for the second time, i decided to get a new heater. I called 1800 plumber at 3 pm and Chad arrived at 5. He went into the attic and re lit the pilot so i would have hot water. Anyway i bought a new heater, which was installed the next morning. Everything was perfect and i highly recommend 1-800-plumber and especially Chad"

Usually, the two most important questions you want to be answered are? What?s wrong? ?And? How much is it going to cost? At Luke's Plumbing, we don?t have a problem giving you a price over the phone. Many Houston homeowners who call us are frustrated because they have called other Houston plumbing service companies and have gotten a run-around when it came to getting a price. It is sad to admit that our industry is plagued with plumbers who intentionally will not give you a price or even a ballpark estimate over the phone because they want to get in your home where they can pressure you face to face into spending more than you should. One of the highest numbers of complaints to consumer protection agency is for home improvement and service companies.. Plumbing license: MPL 37466. A/C license: TACLB 53102E. Call us today for all your plumbing needs!
