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!

John Moore has been a family-owned and operated business since 1965. We understand the trust you place in our company when you invite us into your home. “Call John & Get Moore” is more than our company’s slogan; it’s our pledge to you. We’ll explain everything and provide upfront, honest pricing options, so you feel confident from start to finish. We only hire the very best craftsman and give them the very best training and resources. All of our work is backed by the integrity of the John Moore name.

"recently called John Moore Services for what should have been a simple plumbing issue — a clogged bathroom sink connected to my air conditioner drain line. I reached out after seeing their TV commercial promoting clogged sink service for “about $69.” What I quickly discovered is that this advertised rate applies to an extremely narrow and unadvertised category of sinks that almost no real-world situation meets. My straightforward, less-than-20-minute fix was quoted at over $600 to snake. This is an outrageous markup for such a basic job. As a former small business owner, I find these tactics troubling. This is a textbook example of bait-and-switch advertising — grabbing attention with a low price, then upselling with inflated charges once the customer is committed. Practices like this harm consumers and tarnish the reputation of the many honest, hardworking service providers in our community. Shame on you, John Moore Services. My strong recommendation: Do Not Use."
