"Mike replaced 9 double hung windows in my home with Andersen replacement windows. The quality of work was excellent and the price was very competitive. Mike is very professional and was a pleasure to do business with. He returned my calls immediately, showed up on time, provided a written estimate, and patiently answered all of my endless questions. I highly recommend Hammer Time Contracting and will be hiring them again for future home improvement projects."
