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

"These guys were amazing. I hired them to replace my tankless hot water heater. They took a no need to haggle approach to the estimate process, which I appreciated. The install process felt very white glove, with runners deployed left left my floors and freshly painted walls without a mark. JD was very professional and personable, taking the needed time to do the install correct the first time. They even went the extra mile and fixed an unrelated issue (was not their fault) that would have failed the city inspection. What service! These guys are my new go to plumbers "

"I recently had 100% Plumbing Houston install a tankless water heater in my home, and the entire experience was fantastic! From the initial consultation to the final installation, everything was handled professionally and efficiently. The technician walked me through the benefits of going tankless, helped me choose the right model, and explained the installation process clearly. On installation day, the team arrived on time, worked quickly, and made sure everything was set up perfectly. They were respectful of my home, cleaned up afterward, and even showed me how to operate and maintain the new system. The difference in performance is amazing?I have endless hot water and improved energy efficiency. I couldn?t be happier with the upgrade or the service I received. If you?re considering a tankless water heater, I highly recommend 100% Plumbing Houston. Great workmanship, honest pricing, and top-notch customer service!"

"Fantastic job. Flushed out my tankless water heater then installed something that cleans water so I never have to have it flush d again. So happy. They also fixed a leaking outside faucet that lid put insulation they did not charge me for. I highly recommend them."

"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"

"Company was nice but was charges an additional $250.00!! $165 for a $15 metal pan they placed on my stand before putting the water heater on my stand."

"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.

"David with Armstrong Plumbing Company did an excellent job installing our tankless water heater. They were professional, and had answers for all our questions. They were easy to work with and communicated with us through the entire project. They completed the work cleanly, and made sure everything was done right. We’re very happy with the service. 10 out of 10, would definitely recommend"

"I had a very good experience getting my water heater replaced by Emmanuel. The service was done in a timely and professional manner. I am very pleased with the service that was provided. Thank you."

"I talked to them about installing a water heater Tuesday night at around 7:00 pm and the water heater was installed the next day by 2:30. Great and friendly service."

"I also hired this company the first time to check my tankless water heater. I would give them a 5 star for that too. They are now my go to plumbing company. Steve came out both times."
