WHY CHOOSE US?

NEW WINDOWS AND A WEALTH OF EXPERIENCE

OUR SUCCESS

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.

NEVER ANY PRESSURE

Discount Windows was founded as a place where homeowners and do-it-your-selfers could purchase a wide variety of windows and replacement windows. Furthermore, we carry entry doors, and siding products. All of this without the hassle of high pressure in-home sales presentations or 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.

100,000 SATISFIED CUSTOMERS

Today, over 100,000 satisfied customers latter, we are still family owned and operated. We are now the largest stocking window store in the Rocky Mountain region. This extends from the front range to Summit County. We’ve installed thousands of energy efficient windows, patio doors, specialty windows and much more. In addition, they are in stock every day. We order factory direct from quality manufacturers if we do not carry what you want.
