Texas Quality Plumbing has been in business for over 10 years. We have 15 well trained employees in our company so we can make sure when one of our experts go out to your home you are well taken care of. We are licensed and insured. We also give you a straight forward price. So before we start any job you will know what your price is exactly. When one of our trained professional gets to your home he will thoroughly evaluate the problem and give you a solution.

"We had leak that left a couple of water spots in our home and I called this company because of the good reviews. But we were indeed scammed, the technician quoted us $21k for a “bellying of our pipes”. We had mentioned to the tech that everytime we noticed the wet spots it was when we ran our dishwasher but he never checked our dishwasher or anything. We asked him to do the camera to check our pipes and he concluded the ‘pipe bellying’ due to ‘erosion’ (The pipe camera service is $450 btw, another ridiculous amount.) Well first of all, our home is a NEW build, its less than 5 yrs old so it ddnt make sense to me, plus who has 21k? We went ahead and hired a different plumbing company and within the first 15mins they concluded that it was our dishwasher that was causing the leak! I saw it with my own eyes. They said that i just needed to replace our dishwasher. They said that there’s nothing wrong with our pipes. Which totally makes sense because we noticed the leak everytime we used our dishwasher. Plus they fixed our garbage disposal for FREE compared to Texas quality plumbing quoted us $750 for a new one. How ridiculous. I called Texas quality plumbing because it was upsetting to get quoted 21k and i also asked for the video recording and pictures and a detailed report of the pipe camera service they provided and they cannot provide me with the report. They said ‘we can come out again and the tech will do it again and explain to you where he found the bellying’. They said that they dont even have the initial recording! Another thing to add, since we stopped using our dishwasher we haven’t had ANY LEAKS! PLEASE PLEASE BE CAUTIOUS WHEN USING THIS COMPANY AND MAKE SURE TO GET A SECOND OPINION! THIS COMPANY CHARGED US A RIDICULOUS AMOUNT OF MONEY AND THEY MISDIAGNOSED WHAT WAS WRONG! BOOK A DIFFERENT COMPANY! Attached are photos of their ridiculous prices. Also there’s nothing wrong with our toilets but they also added that we needed to replace them as well. 🤦🏽‍♀️"

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."

When you need an emergency plumber or a drain cleaner, call Roto-Rooter Plumbing & Water Cleanup. Your fast & reliable plumber can fix any plumbing problem, including sump pumps, toilet repair, faucet repair, faucet replacement, garbage disposals, water heaters, bathtubs, showers, and outside faucets. Roto-Rooter is best known for drain cleaning & sewer cleaning. We fix drain clogs, clogged toilets or sinks, blockage of main sewer lines, slow draining shower and bathtub drains, sewer lines and leaking or burst pipes. We also specialize in water damage restoration & water cleanup services. We can fix and clean up your flooded basement too. Roto-Rooter is a 24-hour plumber near you and provides emergency service.

"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!"
