You deserve to work with a team who can predict the unique challenges you might face before the renovation starts. In Colorado, those challenges can be extensive.
We know Colorado. That’s why we’ve specifically curated our windows, doors, siding, and installation techniques to withstand the harsh Colorado weather and the harsh UV rays, temperature fluctuations, and hail damage that come along with it.
Since our founding in 2000, our top priority has been to provide the best for our customers. This standard for superior customer service is the cornerstone of what we do and is why we have earned a 94% customer satisfaction rating.
Simply put — we are more than a business — we are a family. By choosing Nex-Gen, you become a part of the family as well.

Brent Rajewski, owner and president of Nex-Gen Windows and Doors, was quite literally born into the home renovation industry.
His father, Ted Rajewski, trained him at an early age in the most effective techniques for installing replacement doors and windows. Over the years, Brent became an integral part of the family business and realized first hand the importance of working one-on-one with customers to earn their trust and provide only the best products available on the market.
Nex-Gen was officially launched in 2007 and quickly earned a reputation for being the most trustworthy window replacement company in northern Colorado. Today, Brent is proud to serve not only northern Colorado but every city along the front range with two showrooms located in Fort Collins and Colorado Springs.
Brent maintained the family focus of his business by building a team who would honor his mission to exceed customer expectations with superior products and a satisfying remodel experience from start to finish.
The company's rapid growth is largely due to Brent's commitment to excellence and a refusal to take shortcuts which could undermine the trust of his customers. His decision to partner with Marvin Windows, one of the best manufacturers available, and his installation methods have made Nex-Gen the preferred provider in Colorado.
