"They SAVED me $ 3,000. If you need help with a Tankless Water Heater - LOOK NO FURTHER! I had issues with my water heater b/c the temperature could not go above 100 degrees. My first plumber told me that i needed a new circuit board or a new water heater. The second plumber wanted to charge me $ 325 for a diagnosis. I found Affinity Plumbing on Angies List. They came over and was able to fix the issue with my temperature in about 30 minutes, saving me at least $ 600 for a new circuit board or $ 3,000 + for a new water heater as the other plumbers advised. They have REAL EXPERTISE in Tankless Water Heaters and are honest and professional. They are my NEW PLUMBERS! They deserve an A+"

"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!"

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!

"I was having issues with my hot water not lasting too long, Emmanuel came out and diagnosed my water heater had a lot of build up and out of date. We came up with the conclusion to just replace with a new one. I have constant hot water now and set up a maintenance plan with him as well."

"Came out on a Sunday and charged a really reasonable fee. I had a problem with tankless hot water heaters and the person they sent was a specialist in that area - even coming out quickly on a Sunday. All fixed and clear less than five hours after I first started trying to find somebody to solve my problem."

"David Muna was very friendly, courteous, and above all, professional. He explained to me in detail what he was going to and why. Not once did I question his integrity nor his ability to repair my kitchen sink on time and at a reasonable cost. I highly recommend David and JD Precision Plumbing Services, and I would not hesitate to use them again."
