They answered the phone (after several other business didnt) and came right out to do the estimate and complete the work. Quality is good. Will call next time I need sprinkler/landscaping work.
Allegiance is fantastic. Lawson in particular is a total professional. Super knowledgeable, trustworthy, and efficient. Diagnosed our crazy irrigation issues and came up with a cost effective solution.
Arrived on time , perfectly described a job he'd be doing and provided excellent service , would recommend him to all of my neighbors, did a great job fixing my water heater leak
Very professional and responsive. No guess work as to when they arrive. Explained everything and cleaned up yard after they were done. Recommend...
I’ve used this company for multiple services! And they are great at everything they do. They are super responsive to all of my needs and are always on time. I will never use any other company!
They have done several projects for us and they were done efficiently and well. I highly recommend them for any water service
These guys replaced my Water Heater today. Prompt, fair price, easy to work with. 5 Stars is not sufficient to rate their quality
Johnny Gonzales was very professional, courteous, and thorough.
John was very knowledgeable and pleasant to work with. Unfortunately, he didnt have the parts i needed so he will be returning in a couple of days to do the actual work. I will update after the work is completed.
We have used Allegiance Water Services for several years now, and we have not been disappointed. Very professional, quality work, friendly, reliable.
Paul is all of the above plus irrigation systems technologically advanced.
Extremely impressed and satisfied with professionalism and service. A real person always available by phone unlike several competitors I tried to reach. Eloy the tech was the best in all respects.
Lawson with Allegiance Water has done work for us the last few times and he’s very polite and professional and has done great work for us!
I had Eloy come by to repair a water softener system that had failed, as well as replace the filter in the RO system. He was courteous, knowledgeable, responsive, timely, and really knew his stuff.
Excellent communication. Reliable.
Great company! My water heater and water softener both decided it would be best to stop working on the same day. Allegiance came out and gave me a quote for both and their price was great. I feel like they were really interested in helping me.
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.
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.
Lawson installed a reverse osmosis system at our new home today. While he was here, he also helped answer (many!) other questions and helped inspect the home’s irrigation system for me. He was thorough, professional, friendly, and patient. Thanks so much Lawson and Allegiance!
Fast and reasonable.
The service tech was pleasant, courteous and knowledgeable. He tracked down the problem and eliminated it as quickly as possible, as he was aware that what his time cost us in getting the job done.
Excellent service. Rommel was very professional. I will call on them again. Marc C.
I have used Allegiance for years now and every time I'm still amazed at how courteous and professional they are. Every year I have my R.O. filter changed and my soft water big blue filter changed. They also perform my mist services for the backyard with shutdown for the winter and startup in the spring. 100% recommend them!
Great company. We would highly recommend them. Courteous, professional, fast response time. Very reasonable rates. This is the third time we have used their services and have been very happy every time.
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.
Looking into my options as soon as I hear back about my options
Fixed my backyard sprinklers without having to put a whole new system in.
Very smooth transaction! One phone call got the osmosis and softner system scheduled and an experienced technician came and installed both within 2 hours! Great experience. Thank you!
I am so grateful to Lawson for helping me with my spinkler system. He is knowledgeable, kind, and patiently answers all my questions. I trust him and Allegiance Water Service for all of my home’s plumbing needs.
Annual service on RO water system. Rommel was friendly, fast and professional.
John was great. Professional and courteous. Very pleased with his work.
He was wonderfully informative and polite. Educating me on my irrigation system, as I'm from Michigan and very unfamiliar with them.
I had made an appointment for Thursday, but was pleasantly surprised to receive a call on Wednesday that Eloy could come out a day early. They serviced my RO water system and soft water system. They exhibited excellent attention to detail and worked in a professional manner. When finished they cleared explained what we needed to to do move for the coming year. I will certainly use them again for annual inspections and servicing.
Paul and Allegiance are the best!
Lawson was punctual, polite, clean and knowledgeable. He serviced the RO system. Recommended an alarm to detect a leak. Will think about it.
Eloy is just awesome, friendly, detailed, professional and took time to walk me through all work completed, highly recommend.
Would highly recommend. Lawson was very professional.
He installed a water softener system and did a great job. He also updated our r/o system. Very professional
David was terrific to work with to get my endless questions answered and align on the right water softener system. Lawson, who installed the water softener was outstanding. He explained service and care issues and did a very professional install. The whole team takes their customers satisfaction seriously. I'll be back for future plumbing needs!
