"Reuben was right on time and did exactly what he promised. One thing I know about people is whether they are caring or not, and certainly Reuben is one caring individual. I was concerned about a water heater replacement and he said that he wanted to see if he could repair it before we even begin to talk about a replacement. He was able to obtain the materials and put in a new hot water pipe and fittings for the water heater and WOW - hot water! By the way, he has tremendous respect for Vets, police and fire and active duty and gave me a great discount. He's on my permanent list for plumbing! Thank you Reuben for a job well done!"

"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."

"Buddy showed up as scheduled and quickly confirmed that our hot water flow problem was inside of the water heater. He then proceeded to install a replacement water heater at a competitive price and was very professional throughout the entire process. I would not hesitate to call on Buddy again."
