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."

"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.

"They sent tag team to convince me I had sewage flooding underneath my house requiring $2k of work. I watched closely and crawled in hole they dug myself. There was no flooding nor sewage backed up. I had to pay half up front and refused to pay second half. They finally agreed with my analysis but I still haven't been reimbursed at least partially. I will never do business with them again for any type repairs."
