"I hired USA Water Heaters to replace my broken Tankless Water Heater with a new unit. I contacted them through their website about 10AM describing my problem and they responded with a quote and two options in about 30 minutes. I opted for the upgraded unit and by 12:30 the same day the technician arrived to install a new water heater. The installation took about 2 1/2 hours and the workmanship is excellent. I am a very satisfied customer and would use them again. The one day service was a big plus."

"Installer Tony G. (5 stars). Very competent; very complete. At every step he explained what he was doing and why. Answered all of my questions. Company itself stands by its service (both the install and the water heater itself). All ancillary equipment replaced and up to the latest codes. Water heater itself (Bradford White) is top grade (and made in the USA). Again 5 Stars for Tony G. and The Water Heater Company."

"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."

"Found me the right size water heater, a few days before Thanksgiving and had it installed within 2 hours. Clean and efficient and Bradford White gas water heaters are American made. Built to last. Daniel Westereng did a great job with the install. Clean, fast, thorough and polite."

"Very professional and courteous, the contractor that worked with JIG Plumbing was also excellent. Here on time everyday, left the area clean or out of the way at the end of each day and completed the project within the time and price they quoted. They did a great job remodeling the bath, updating my bedroom and retiling my the floors in the bedroom, dining room and hallway. I even had JIG repipe my main sewer line during the remodel process. I will call them for any job I need done concerning my home interior or plumbing needs. I highly recommend JIG Plumbing for the your plumbing and remodel projects."

"They took out my old shower and installed a new one. They came out quickly and installed the shower kit and door within 5 days, despite heavy rains that week. Customer service was great. They were professional and came out again when we asked to adjust the shower water temp to get hotter. Even though they had to add additional framing for the shower door, they only charged my for whatever was quoted in the beginning. Overall, I was very satisfied and would work with them again."
