"David with Armstrong Plumbing Company did an excellent job installing our tankless water heater. They were professional, and had answers for all our questions. They were easy to work with and communicated with us through the entire project. They completed the work cleanly, and made sure everything was done right. We’re very happy with the service. 10 out of 10, would definitely recommend"

"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!

"I would absolutely recommend Tradition Services to others. They were prompt, courteous and extremely knowledgeable. I initially needed HVAC repair but after chatting with them about some other issues I was having, I ended up getting a tankless water heater as well. I’m excited to see the different it makes in my home! Thank you, Tradition for being forthright!"
