These Guys are awesome! They were on time and on the mark. Service was professional and they did a clean repair. I would definitely recommend them.
John was extremely professional and courteous explaining in detail the problems with my irrigation system. He made the repairs and added recommendations as well. He was the best! I highly recommend! Pull
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.
Excellent job! Will use them again.
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.
After 5 years we had water softener , we found out we use soft water for our pool and watering the plants in our back yard , so I called this company they responded fast and the next day they sent their technician Ruben . After we agreed on his estimate , he came the next day. He did awesome job on separating our soft water. Ruben was knowledgeable, fast and reliable. I am so happy with his work and recommend him and this company to everyone.
Allegiance Water Services are prompt, thorough, and professional. I found them when they did work on my next door neighbor’s irrigation system. When my irrigation started leaking and watering weeds, I called Allegiance Water Systems for a quote and then to schedule repairs. They send text messages and emails with links to track your technician or to call them direct. Invoicing is quick and easy to access via their billing system. You have everything in writing with links to confirm, deny, or modify your service needs.
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.
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.
Fast and reasonable.
Allegiance has been great. Eloy was perfect. I recommend this company highly and will certainly continue to use them in the future.
I have used Allegiance Water since 2018. The company and service is outstanding. John Gonzales was our repair person for this call. He changed our RO water filters, installed a leak detector for the RO, and repaired our water shut off valve. He was GREAT!!! He is very knowledgeable and dependable. I highly recommend Allegiance and their team. Thanks
Friendly, knowledgeable and efficient.
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.
Annual service on RO water system. Rommel was friendly, fast and professional.
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!
Johnny Gonzales was very professional, courteous, and thorough.
They have done several projects for us and they were done efficiently and well. I highly recommend them for any water service
Technician was here within 30 minutes. Did a great job for a fair price. I highly recommend Allegiance…..
Lawson was incredibly friendly, informative and professional. David was also a standout for his strong communication and customer service. 10/10 would recommend to friends and family.
Fixed my backyard sprinklers without having to put a whole new system in.
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.
Very professional and responsive. No guess work as to when they arrive. Explained everything and cleaned up yard after they were done. Recommend...
Eloy is just awesome, friendly, detailed, professional and took time to walk me through all work completed, highly recommend.
Excellent service and water quality!!
We have used Allegiance Water Services for several years now, and we have not been disappointed. Very professional, quality work, friendly, reliable.
Friendly and reliable. Does great work!
Josh and the office and service tech Rommel were excellent in every way! Professional, knowledgable service of issues with my water softener.
These guys replaced my Water Heater today. Prompt, fair price, easy to work with. 5 Stars is not sufficient to rate their quality
We had a leak in our drip system. Johnny was awesome. He took the time and explained what the problem was and how to get it fixed. He didn't have the part...
Allegiance Water Services was great! They prioritized my urgent request and Lawson was great when he came to diagnose the issue. He thoroughly explained the problem and gave me different options and advice on future work. 5 star support!
Lawson Key was very professional, respectful and kind. He did a great and solid job of installing a new faucet for our water filtration system!
He was wonderfully informative and polite. Educating me on my irrigation system, as I'm from Michigan and very unfamiliar with them.
