About Discount Windows in Denver, Colorado

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.

Windows, Siding, Patio Doors and More

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.

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.

Family Owned Window and Patio Door Store

We are still family owned and operated today, with over 100,000 satisfied customers. Additionally, we are now the largest stocking window store in the Rocky Mountain region with thousands of energy efficient windows, patio doors, specialty windows and much more in stock every day.

  • We custom order factory direct from quality manufacturers what we do not have in our store.
  • Serving the entire Colorado front range and Summit County.
