"Elderly Abuse …. Run I woke up to a leak in my front yard as I headed out of town. My wife called Roto Rooter as she left for work to come give us a quote. They said they only needed someone there to greet them when they arrived. So we had my 85 year old, legally blind, suffering from dementia mother, who lives next door, meet them outside so they could begin with their estimate. They never called us for a quote. Instead he replaced one section of pipe (which was only 4 ft. long), and a shut off valve (which he said was broken but was not) and charged a whopping $6,500. He walked next door and demanded payment from my blind mother. NO APPROVAL WAS GIVEN!!!! NO PHONE CALL WAS MADE!!! My mother, who isn’t mentally with us anymore, gave them her credit card and boom…… $6,500. We didn’t get a new water heater or a new sprinkler system. We got one 4 ft. section of pipe for $6,500 and a shiny new on/off valve which was not needed. That guy new what he was doing. He didn’t call us for a reason. He took one look at my blind old mom with dementia and charged whatever he wanted. He left us an arbitrary bill I could hardly read with little to no specifics. I have attached…. When I called the manager he did return half of the amount. It sounded like we were making progress. I still asked for an itemized receipt so I could see how 4 ft. of pipe and a valve would cost $3,250. If I stayed in town this repair would have cost me a total of $75 dollars in materials. He said he would get that itemized receipt and then has ghosted me ever since. I have reached out on numerous occasions. This company did not have permission to do $6,500 or $3,250 worth of work on my property. They were called for an estimate and took advantage of my elderly, blind, dementia plagued mother to run up a huge bill that no one can explain. They demanded that my mother, who isn’t the homeowner, pay $6,500. My wife waited by her phone all day for an estimate that never came. This is morally and ethically appalling at every level. Just for reference, we had our foundation lifted for $9,000 last year. They dug under the house in several areas and lifted it. This guy wanted about the same for replacing a 4 ft. section of pipe. How is this real????"

"Our landscape architecture and construction studio, Twistleaf, contacted Texan Water in spring 2023 to assess the condition of an existing well at a clients property in Fredericksburg, in preparation for a large-scale landscape renovation project. Their technician was the consummate professional. Extremely responsive and knowledgeable, he took the time to answer all of our questions in person, then always followed-up with reporting and work orders as promised. After the initial assessment and with the passage of time, it was clear that additional work needed to be done on the well, which Texan Water executed in a timely and reliable manner, in concert with other trades working on site.

"Rude and agressive behavior for absolutely no reason towards female customer ! Work was partially done to be finished but the owner after being asked to explain the work that will follow aggressively pooled out the previously fixed item claiming it was his and not yet paid for! I was standing there ready to settle which was not an issue to begin with! Be aware of this very unprofessional service!"

"Initially we thought we had found a good company to service our well issue. They came out immediately to look at issue and gave us a solution we thought to our problem. Within a month, our well again was flooding well house and should have been covered under their warranty. We called multiple times and finally connected to be serviced. That day came any went without anyone showing up or calling to reschedule. Follow up calls got us nowhere until I left a message that if I didn?t get a callback, I would place an honest review on the bad service and unprofessional message from them. The well guy called back with excuse everyone at company had flu and to go ahead and leave a negative review. So here it is. They are quick to get out and make a buck but not follow up on any issues thereafter under warranty. If the well guy would kindly correct this situation, I would in turn follow up with a positive review of them correcting a situation for a customer. "
