"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"100% recommend. Very professional in every way as the other reviews say. Geremias and his nephews installed a tankless water heater for me, and it works great. Punctual, responsive, communicative, trustworthy, and the best price. I couldnâ t ask for better."

"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."

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"Replaced water heater supply pipe, using compatible materials--previous installer had used different materials that resulted in electrolytic corrosion. Service was reasonably prompt and courteous, explanations clear and enlightening. Pilot light went out after service, repairman came back to relight, and explain how to relight."
