We started in 1981 doing retrofitting in older homes by changing out single pane glass to double glass and triple pane. We reused homes existing window frames to make them more energy efficient.
By then, all new homes came with dual-pane glass, but the trouble was the quality was very poor and the seals began to fail. It did not seem to matter what brand of window, the windows had seal failures.
Since then, we have replaced between 40 and 45 thousand thermo-pane window units. The process is two step we come to your home and determine your window and glass condition, measure the glass for exact size and return on a second trip to install them, usually you are without glass for only about 15-20 minutes.
If your window frames are in very bad condition we will recommend a window replacement that fits your home and budget. No dog and pony show, no 2-hour sales pitch, just the best quality at the best price! Don’t waste your money on cheap windows, we have replaced windows on homes built in 2006 and 2007 that are already junk.
S.R. Window and glass prides itself on excellent customer service, an extensive glass and window product line, and skilled installation. Experience the difference!

Mountain View Window & Door was founded in 2006 in Centennial, CO. In February of 2012 MVWD was purchased by Devon Tilly and moved to its current location on tile row. The 10,000 sq. ft. facility underwent major remodeling, and we are very proud to share it with our clients.
We opened our second location in 2014. We found a great building called, Fairmount Hall, in Grand Junction, CO. It was a small building directly south of the Ale House on 12th Street, originally built as a meeting place for and by Fairmount residents in 1922. It was a wonderful place for us to get started in the community. As a company that is growing FAST, we outgrew Fairmount Hall. We recently moved into a larger space that will be a part of a beautiful design center offering a showroom our clients could only dream of!
All of our employees are the most experienced and qualified in their positions and are eager to provide you with the best window, door, and hardware customer service you have experienced.

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.
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.
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.
- In addition, we offer turnkey installation services to our customers that want that.
- And of course, we will always provide free expert advice and know-how to the do-it-yourselfers.
Many companies pay lip service to providing great customer service but here at Discount Windows & Siding, INC. we take pride in delivering excellent customer service to everyone we work with. We know that satisfying customers is not only the right way to do business but leads to referrals which account for over half of our new customers.
