Enoch Electric, Water, & Air, is an electrical, plumbing, & HVAC contracting company passionate about providing the best value and service in the industry. The company was founded by a DFW native engineer and real estate investor who became disenchanted by the lack of morality in the construction industry and decided the only way to combat it is to participate. We are professionals with over 30 years of experience that specialize in both residential and commercial electrical work. Give us a call today and allow us to earn your trust!

"We spent 14K on two new AC units for our house in 2021. We had to get the technicians out almost every year and multiples a year because something is always wrong. Some technicians were not experienced enough to diagnose the problem and wasted hours at our house. They also made careless mistakes (not connecting the draining pipe back in the attack) in Aug 2025. We had to run very loud fans for 5 days just to dry the water leak from the attic to our ceiling. The same technician was sent out in Nov 2025 and made the same mistake again. Now our ceiling is leaking again. The customer service did not even acknowledge or apologize for what we are going through. I am now worried that repeated leak may have caused permanent damage to our house. I do not recommend this company."

Since 1992, JD Precision Plumbing Services has been serving The Woodlands, TX and it’s surrounding areas in all of its plumbing needs. If you are looking for dependable, honest and hardworking technicians we are the plumbers for you. Call us now to schedule an appointment!

"Be very careful if you need any plumbing work done in The Woodlands. DO NOT call JD Precision Plumbing, they are modern day Pirates. They charged me $800.00 to replace this one small section of water main. took every bit of 30 minutes. They say free estimates on their website. When I called for service, I was told there is a $175.00 service call charge and would be I would be credited this amount if work is done. I'm thinking it cannot cost much over $175.00 to fix. (wrong). They estimated $791.00 to fix it. I'm not home due to a surgery and have buddy relaying info to me. I think ok, the $791.00 less the $175.00 so $616.00 to me. (wrong again). I not only get charged 791.00! they added 3% for using a credit card. Now I'm at $815.00 to fix. I try getting justification on charges from their operations manager only to be told JD Precision plumbing is so big and they have higher overhead than any other plumbers, therefore have higher costs for service. I call BS."

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!
