Nex-Gen Windows & Doors

Great company to deal with, as well as quality windows. The crew installed them quickly, and professionally. There was a minor glitch at first, but customer service and the company resolved everything completely! I'm so happy with my new windows!

Nex-Gen Windows and Doors in Fort Collins recently installed new exterior doors on my home. From start to finish, I had a great experience with this company. The people at Nex-Gen provided a winning combination of high quality products, expert installation and exceptional customer service.

I knew that I would need help choosing the right doors for my home. Luckily, my salesperson was Clark Mace. Clark was knowledgeable and very thorough. He knew the products inside and out. As he guided me through the many style options, his suggestions were invaluable. Thanks to his expertise, I now have a beautiful new front entry door that complements my home. What a transformation!

Clark stayed in touch every step of the way. He even stopped by to see the completed project. That level of commitment to customer satisfaction is rare, and very much appreciated!

Great service and product . Thank you Eugene, installer, and Don, PM

Great products and professional people

Everyone i have worked with at NexGen has been professional, courteous, responsive and the workmanship is top-notch. Will be reaching out to them to also get a quote for siding.

When replacing all of our windows, the company we were using could not change four windows into two long ones, saying they would be too big. Nexgen’s frames were stronger and they were able to make the two long windows, eliminating the 8” space between. It made a world of difference in our living room! We wish we had used Nexgen for all of our windows!!!!
Everyone at Nexgen has been terrific - from Ted, the sales person to the installers.
We now have another project so I immediately contacted Nexgen.

Had an issue with our door jamming and Mike came out and fixed it right up in about 15 minutes!

We love our new door. High quality fiberglass construction and the door is efficient at blocking heat, sunlight and sound. The installation was efficient and they did quality work. Very happy with our experience with NexGen so far!

NexGen replaced 3 windows in my patio home. The quality was what I was looking for in windows. The installers did a good job and left the inside and outside of the windows looking professional and well installed.

We’ve had our NexGen windows for about a year now. In the winter time when all of our other windows had condensation, the new ones didn’t. The product is excellent. We even saw a reduction in our heating bill. Ted is wonderful to work with. Highly recommend.
