Get To Know The Nex-Gen Story

Local and Proud of It.

Who we are

Nex-Gen is a second generation family owned and operated business with more than 35 years of experience in helping customers with all their home exterior needs including replacement windows, doors, and siding. We serve Northern Colorado and Southern Wyoming, and we are grateful that so many homeowners and housing associations have given us the opportunity to help them.

Why we are different

When we sit down with our neighbors to give them our recommendation, we advise and share our experiences but at the end of the day, we want our customers to make the decision that’s best for their family. No need to decide on the spot, just call us when you’re ready and we’ll be there to get the job done right. The best compliment we get is when we see a customer at a local restaurant or shop and they tell us how much they like the product we installed. We want that kind of relationship with our customers based on trust and quality products.

Our Story

Welcome to Nex-Gen Home Exteriors.  We are a family owned and operated business with a commitment to excellence for each and every customer.  With over 35 years of experience in the window and door industry, we have learned the secret of setting ourselves apart from every other company.  

We recognize the importance of offering the highest quality, time-proven, and trusted brands of leading-edge products at competitive prices.

We will do business with Nex-Gen again, hopefully soon. I recommend them and their work absolutely without hesitation.

From the initial contact at the Greeley Home Show, to the actual sale meeting, to the measuring session, through installation and final staining and sealing, our experience with Nex-Gen was exemplary. Friendly people, quite knowledgeable, and highly enthusiastic about their products, the fellas made buying our bay window easy and fun, too. We are impressed with the quality of workmanship of the window itself, and with the professionalism and talent of our installer, Brent. He was efficient, and precise, getting the entire complicated procedure completed in one session of less than 8 hours. He was very careful with tools, very cognizant of the fact that he was in our home with us, and he cleaned up his work impeccably. We will do business with Nex-Gen again, hopefully soon. I recommend them and their work absolutely without hesitation.
