"My water main went out on Christmas Eve leaving me without water, Wes offered to come out on Christmas day to make the repairs. I told him we could wait until the next day, he arrived on time, dug up my very rocky soil to get to the water main and made the repairs. The customer service was great and he explained everything to me every step of the way. The cost was also reasonable. I have asked that he return to make an additional repair later this week. He definitely has a repeat customer."
