"Hank provided me with exceptional service! Even though this work was after normal business hours, he contacted the plumbing supplier and worked with them to re-open their warehouse to obtain the necessary water heater. Hank finished the job that night and verified that everything was in working order. I am very pleased with the quality and customer service Hank provided. Hank even helped me move a large storage cabinet back into place after the work was completed. Customer service going above and beyond expectations!!!"

"There are not enough stars to represent how AMAZING these folks are! I needed a tankless water heater installed. They went above and beyond to be sure my wants were covered but also that I understood what tankless water heating is, the different options in sizes and speck they also made sure I understood the unit they recommended and ultimately chose. I know how it runs now, what to expect from it and more. If you have ANY home projects in need of a professional trade person….. HIRE THESE FOLKS! I promise you will not regret it."
