"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!"
