We had sears windows installed 18 months ago; Wanted to make sure they lived up to their promise. They come with a 50 year warranty and free replacements for windows and screens that get damaged or warp. Our house has been a lot warmer in winter and cooler in the summer. They also have drain flaps so the water goes out and bugs don't get in. The spiders have decreased by about 90%. The company sends a person to your house and shows you how their windows compare to the other companies out there and there is no comparison. It was 20 degrees outside and the inside glass panel was only cool-not icy and frosted as our old windows were. Call them today, 12 months no payments so it's worth looking into. They're not cheap so think about the investment wisely!! well, don't hesitate if you need windows that are worth every penny and you will see a great increase in property value with the windows. Ours appraised for twice what we paid for them.
