About Colorado Window and Siding, Inc.


Colorado Window and Siding - Serving Colorado for 26 Years!

Founded in 1983, Colorado Window and Siding set out to simply provide quality products and a great customer experience in the window, door and siding industry.  To succeed in this, we’ve followed these five guiding principles:

  -  Work only with quality manufacturers

  -  Hire skilled installers who are well mannered and professional

  -  Listen to the customer and help each customer find their best solution

  -  Compete on value, not sales tactics

  -  Stand behind our work

For 26 years we have been living by these principles, and they have not let us or our customers down. We have enjoyed the fruits that comes with doing business the right way. Today, over 60% of our new customers are referrals and repeat purchases from the many happy customers we’ve served over the years.  We are very proud of the customer experience we deliver and we are humbled by the support we receive from our customers year after year. As we look forward to the next 26 years, we will continue to live by our principles and strive every day to deliver the best customer experience in the business.
