"They came. They saw. They conquered. Plus it was affordable for the job. No excuses, nothing, but hard work. Once they arrived, they let us know they were there. We showed them where to look, and they went right to work. Hats off to those guys for doing the sh**ty jobs (pun intended) I don't wanna do, and for doing it with smiles."

"At first the company seemed super helpful. Eric was always pleasant and seemed to be supporting us. HOWEVER, they told us that they were dealing directly with insurance and that we wouldn't need to worry about anything. Therefore no costs, no options, no explanations of services were ever given to us. When the bill came back higher than insurance would cover they assured us that Joyce was the best in the business and would get it taken care of for us. the gap ended up being $3000 out of our pocket and as far as I can tell, no genuine effort was made to come to an agreement because we would have to pay it anyway. They were not actually working for us. In addition, the whole process was frustrating because appointments were made with us, where we canceled plans and they never showed or called. They removed equipment before it was dry and then covered themselves by putting it back in. At the end of the day our house is dry as is our bank account. I DO NOT RECOMMEND!"

"Cedric quickly diagnosed the faucet issue and attempted to repair it. After determining that it was unrepairable, he ordered a brush nickel faucet that matches our kitchen sink. He suggested that we join the Home Protection Plan for service savings. Cedric is courteous, knowledgeable, and professional."

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!

"Awesome service -- prompt and professional -- from Jason on a shower job. Recommend highly."

"This company offers fair pricing and quick response times. I made an appointment for an installation of a new kitchen faucet along with two angle stop valve replacements. Bill and helper arrived right on time. Friendly and ready to work. They went straight to work and completed the job promptly, testing and checking the system thoroughly. Bill also made me aware of some future services to consider in a knowledgeable, non-pushy manner. I certainly will think about it and give Warren’s a call when I’m ready."
