Get matched with top tankless water heater repair pros in League City, TX

"James and Lance did a great job. In spite of three problems coming up during the repair/replacement, both pushed through and completed the job, staying later than any of us expected. It also doesn't hurt that Courtesy stood by their quote which was a fraction of the first plumber's quote."

"They did a great job installing my new water heater. During the quotation they were very nice and helpful with suggestions and things to look out for. Then, they picked it up from Home Depot, completed the install, cleaned up, and even looked at another issue I had during the same visit. They were very nice throughout. Highly recommend."

"They were great! Mr. Heaton (37 years as a plumber) was quick to assess, explain and repair our issues."

"I had a 14 year old water in my attic and after the pilot lite went out for the second time, i decided to get a new heater. I called 1800 plumber at 3 pm and Chad arrived at 5. He went into the attic and re lit the pilot so i would have hot water. Anyway i bought a new heater, which was installed the next morning. Everything was perfect and i highly recommend 1-800-plumber and especially Chad"

"They gave me a quote to replace my tank less Hot Water heater, and once I agreed to the quote, they performed the work quickly, and efficiently! The workers were very polite, proficient, and did a great job!"

"We began a complete gut/remodel of our kitchen, doing all the work ourselves except the new vinyl flooring.  The remodel involved moving our refrigerator to a different wall.  When I closed the shutoff valve for the fridge water supply, it didn't stop the water completely.  Not a problem, I thought, I'll just replace the valve.  One turn of my wrench and the valve broke off -- turns out the builder had put an iron elbow onto a copper pipe, and the whole thing corroded.  It had probably been dripping for years inside the wall.  Since we were moving the fridge anyway, I called Alliance (who we have used many times) to get them to cap the old water supply pipe.  I also wanted them to replace the shutoff valves for the sink since we would be tackling that next, and I didn't want a hassle if they didn't stop the water completely.
Stephen arrived on time and began work.  He quickly capped the defective fridge supply pipe, and then he replaced the hot water valve under the sink with 2 90-degree all-metal valves, one for the faucet and one for the dishwasher.  He also replaced the cold water supply with a 90-degree all-metal valve.  I wish I'd have thought of doing that -- if I need to disconnect the dishwasher, the faucet still has water, and vice-versa.  All this work was in the neighborhood of $500 and change.
We asked Stephen about pulling cold water to the fridge icemaker.  He got up in our attic and asked us to make a note of what he was tapping on.  When he came down, he said a cold water pipe ran down the wall right where we wanted the fridge to go.  We arranged to call Alliance back when we finished getting the old cabinets out of the way so the fridge work could be done.
Stephen came back out a few weeks later and braised a "T" onto the cold water pipe in the wall, ran a short length of new Pex to a new 90-degree all-metal valve for the fridge water supply, and mounted everything into a plastic wall housing.  It looks good, a nice professional finish.  This second job was $590.
We like Alliance Plumbing because they're punctual, professional, they do good work, and they have a price sheet for jobs, so you know what it's going to cost up front -- no surprises.  Their prices usually seem higher than what I expect a job to cost, but to be fair, nobody calls a plumber when their day is going great.

"Enoch responded immediately when our water heater went out. Affordable, on-time, and the installer was courteous and did excellent work. I highly recommend Enoch for your water heater replacement."

"Eliazel recently performed a water heater flush and general check of our home. He arrived early and was very professional and polite. He did an excellent job for a fair price. I highly recommend him."
