We live in a rather old house and decided to do some renovations, especially to our old windows which suffered from interior condensation in the winter. This was about a year and a half ago. Eventually, we decided to change all the windows of the house. Deluxe windows was very helpful and gave useful suggestions as well. Since I grow a number of orchids and flowers inside the house, frosted glass was suggested and was very effective in giving me just the amount of sunlight needed. Their customer service was also very good. My son's window had a little bit of condensation and they had a worker sent over to fix the window very quickly. There are some companies whose service does not last well after the initial purchase, but I am glad to say that Deluxe Windows lived up to my expectations.
