About Us

The Gill Window Company was started in 1988 by Nick, Mike and Kevin Gill, when they saw the need for a quality product. Back then, the company purchased their windows from Denver and only provided the installation, but soon realized they wanted to be able to provide a better product for their customers. With the help of an Economic Development Loan, they started manufacturing their own windows in a little 3,000 sq. ft. shop and soon developed a reputation for having the best window products in Wyoming. Today customers drive in from all over Wyoming, Colorado and Nebraska to buy Gill Windows.

Over the years, Gill Windows has had the opportunity to become a mass producer like Pella and Andersen. However, they decided to remain a small business in order to align with their values of quality over quantity.

“We’d rather make a few really good windows. They are an investment and we want to give our customers the best product and service there is.”

Today Gill Windows now has a 20,000 sq. ft manufacturing facility with a crew of 30-40 people and continues with the belief that their customers are and always will be #1. They are licensed, insured, bonded, and a member of the Cheyenne and Laramie Chamber of Commerce.
