REPLACEMENT WINDOWS AND DOORS Keeping a warm house in the cold time of year is not just convenient and pleasant, but it is also financially sound. Our calculations show that the average household wastes hundreds of dollars a year on energy spent on heat loss in the winter. Our vinyl windows are built with fusion-welded sashes and frames, making them impregnable to water, snow, or air when sealed. The effect is made perfect by the double insulated glass. Keeping that heat inside the house means yearly savings of hundreds of dollars, which also means that our windows and doors essentially pay for themselves.
