I wanted to THANK YOU for providing a TERRIFIC product on our full home replacement windows with DMD. It's amazing that we never realized the VAST difference in window quality until you installed your product. The upstairs floor of our home, where we have two additional guest rooms, was previously unusable in the summertime due to the infiltration of sun/heat. Since you replaced our windows, we are amazed that we can go upstairs and it is the same temperature as the lower floors of our home. I couldn't believe the difference. Additionally, the noise level from outside is markedly reduced with our new windows. Again, we never realized how much noise infiltrated through our old windows and sliding doors until we got them replaced by DMD. We are THRILLED with our decision to use DMD and the terrific California made windows you recommended. We will certainly refer other friends and neighbors to you if they are looking for new windows. Thank you again. This is one of the best investments we've made in a home in over 30 years!
