Paul came today to check my Rain Bird system controller. I have worked with him during my new irrigation installation project at the beginning of this year. I was extremely pleased with the outcome then and again today. I specifically requested him for today’s job. As always, he offered excellent, professional service, knowledgeable, courteous and friendly. I would refer him and Allegiance Water Service to my friends with high remarks.

I had an exceptional experience with Allegiance today. My old gas water heater needs to be replaced. I called Allegiance yesterday and discussed with David who is very knowledgeable, transparent and told me pros and cons among the different water heaters. I decided to go with 50 gallon Bradford White water heater. Ruben came in next day and clearly explained to me what is the process. He is excellent, very skillful and told me how to maintain it. He cleaned everything afterwards. I am very happy with their services and will call Allegiance for my plumbing issues for sure. Ruben from Allegiance Water Services did an excellent job again today. I had water hammer issue for a couple of months and my pipes coming out the main pipe weren't connected right by a previous plumber. The irrigation system controller needs to be replaced as well And it is now upgraded to an enabling phone control unit. Ruben did an excellent job on replacing the unit and repiping everything. It only took him an hour and they work great! Ruben is very experienced, knowledgeable and efficient. It wouldn't go wrong for Ruben to do your plumbing jobs.

Allegiance Water Services sent a repair man to fix a broken sprinkler head.. He was courteous, pleasant and well informed. He fixed the head and checked to be sure the whole system was working again correctly. I appreciated his service. Thank you

Why should you hire Allegiance? Quality. Dependability. Customer service. Experience. Dedication. Hard work. This company takes quality experience and service to the next level. I haven’t worked with many home service companies who do such a good job like this. From the moment we got the quote, until the minute the job was done, they were reliable and they provided the service we requested. First they came out to inspect the issue. Once they figured out what was wrong, they provided a verbal quote and followed up with a digital quote. I was able to accept the quote digitally and put a deposit down to begin the work. Since our system needed to be replaced, it was quite a process and luckily they had it all under control. They contacted the city and cox communications to flag their underground items so that they knew where to avoid. Then Lawson came out and literally spent an entire day replacing the system. The customer service was above and beyond. Yes there are a million plumbers and irrigation companies out there, but there aren’t as many reputable, trustworthy, licensed and qualified ones like Allegience.

John was on time and professional. He fixed the leak in my backyard system and tested it to make sure no further leaks. He also checked the front yard and found an additional leak that I hadn’t noticed and also fixed it in the same trip. Super happy with the great service and will definitely call these guys again for future plumbing repairs outdoors and indoor.

Had an issue with my sprinkler system, something failed and I had a big wet spot on the side of my house. Called in and was helped with instructions on how to turn off the sprinkler side so no water would go to it until a repair could be scheduled. Paul comes out and shows me the problem, we set a time and he fixes all of that, THEN while testing, just waltzes into the spraying sprinklers and dials in where the water SHOULD have been spraying, like " oh, that's the wrong direction to spray for this area..." Then he programs the whole thing to fix my already mediocre lawn and bushes, told me what to do to improve my lawn through yard care and got into his car with soaking pants and thanked ME! 10/10.
