"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+"

"The company Affinity was wonderful. This is the second time we have had the Navien tankless hot water heater repaired. The first time it caused massive damage to the bedroom below. I pleaded with Trendmaker to put the hot water heater on the ground floor. But they stood firm. So we had the tankless heater put in in an effort to avoid just the trouble we experienced. Affinity fixed the heater when it froze during the recent freeze. It is not Affinity's fault but the parts are expensive so the heater is much more expensive to maintain than an ordinary hot water tank that SHOULD be on the ground floor. So I give an A to Affinity for great service and an F to tankless Hot Water Heaters and to Trendmaker for being so stubborn about putting a water tank in the attic."

"The company came within 2 hours of contact and inspected my water heater. We received a quote before the plumber left. The next day, Jacob the plumber, followed up with me to see if I still needed their services. I called him back to let him know that I did. Within 2 hours he was back at my house to replace the water heater. He was done replacing the water heater within 2 hours! I haven’t had any issues since the repair. Thank you Plumbing System Pro for your awesome service!!"

"The gentleman did an okay job at flushing my water heater , however he spilled water in my attic which then leaked over my bathroom and tried to convince me it rained and my roof was leaking. At the end, he hired some guys to replace the ceiling in the bathroom at the company expense."

"I got a phone call from the business shortly after posting the need for restart to the water heater as CenterPoint had turned off the gas. The service was prompt and bought a new water heater as the old one needed to be replaced. Reasonable price for replacement and 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!

"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."

"Kris Aylor from 1-800-Plumber of Pearland is the technician who did the work replacing my water heater tank. He is very detailed and did excellent work completing the work within 3-4 hours. He also fixed other three plumbing issues I had not related to the water heater. I was very happy with the way he took care of my plumbing issues. I also found the cost with 1-800-Plumber much lower than other major plumbing company who gave me their free estimate. Kris also gave me a one year free Home Guard membership worth $199 for annual inspection and maintenance of AC, Heater, water heater and other plumbing related items. I will definitely use 1-800-Plumber for any future plumbing issues I may have."
