We owe our success to a very straightforward idea — sell only high quality windows, doors, and siding at low discount prices while providing outstanding customer service. This is our commitment to our customers. In 1984 in Denver Colorado, Discount Windows & Siding, INC (DWS) began practicing this approach as a small family owned and operated business. Founded as a place where homeowners and do-it-your-selfers could purchase a wide variety of new and replacement windows, entry doors, and siding products without the hassle of high pressure in-home sales presentations and the high prices and gimmicks that accompany them. At DWS there is, and never has been, any pressure to buy and we give free estimates in writing.
