We had RDM Construction replace all of our windows recently and we are very happy with them. Our home stays cooler, cleaner, and quieter. It has been amazing to see the difference in the heat coming in the windows. I am sure that we will really notice a difference when the weather cools off also. Besides that, it is nice to be able to see out of them. Our old windows were so bad that was not easy to do. Thanks RDM.
