From start to finish our experience was exceptional! We had 27 windows installed and siding to match existing siding for half of our house. Every crew that came out was professional, on time, non-intrusive, friendly, and caring. Not to mention they were all experts in the job they were performing. This was a huge project for us and we were very concerned about follow through as many contractors start out good but then they end up not finishing usually at least one little thing. We had head people from Nex-Gen coming out to our house on their own just to check to make sure things were done right

Nex-Gen installed all the windows in my house and I couldn't be happier. The windows are top quality and look fantastic. They came back to stain the framing and did a very beautiful and meticulous job. Everyone I've worked with at this company has been very helpful and friendly. I highly recommend them.

These folks are the best! I hired them last year to put on siding, frame doors and windows. This year I hired another company to repair hail damage. They slapped on a roof and left me waiting 5 months for new windows. I fired the crooks and placed a call to Next Gen. Ted was at my house the very next morning to get my problem solved. I've been so pleased with these guys I asked them to do the rest of the windows we didn't replace last year. The estimate was very reasonable, and I can trust them to get it done right.

Nexgen replaced all my windows and a sliding glass door with the Marvin Infinity (fiberglass) model.
The crew kept the inside of the house very clean but made a big mess outside. They used a Sawzall to remove the old vinyl windows and now I have tiny vinyl pieces scattered all over my yard and mulch with no easy to way to clean it up. The caulking is a big part of the finish quality for this kind of window replacement job; unfortunately, there were a few windows with sloppy caulking.
A few of the windows have a grey foam tape sticking out of the corners. The installation crew said that this tape

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

The level of professionalism and product knowledge is outstanding. Everyone from those who answer the phones to the client experience manager, field managers and installer was simply amazing. They work hard to pair you with a product to fits your needs. This company doesn’t just take your money and then leave, never to be heard from again- they do follow up and they make themselves readily available to address possible issues or concerns.

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!

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.
