Lonestar leak detection came out 3 times to try to diagnose and repair our pool leak and charged us twice for complete diagnostic and tried 3 times to fix the leak. our pool still leaks and under repair warranty but now they will respond to my calls . I have paid all my bills. I am not even sure at this time that the diagnostic was accurate or possibly leak was ineffectively repaired cost me $ 900 but my pool still leaks. poor work, won't honor warranty. I would look for someone else. They are on the web as lonestarleakdetection.com!
