About DWS

We owe our success to a very straightforward idea. Selling only high quality windows, doors, and siding at low discount prices. All this 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. We started as a place where homeowners and do-it-your-selfers could purchase a wide variety of new and replacement windows. In addition we carry, entry doors, patio doors and siding products without the hassle of high pressure sales presentations. At DWS there is, and never has been, any pressure to buy and we give free estimates in writing.

Windows, Siding, Patio Doors and More

In 1992 we moved to our current high visibility location at I-70 and I-25. Then we began to warehouse thousands of windows that we purchase at deep discounts and then pass the savings on to our customers. Custom window ordering and installation by this time was also a cornerstone of our business. We began ordering factory direct to receive the lowest possible pricing. Consequently allowing us to aggressively discount and provide amazing value to all of our customers.
