Nex-Gen Windows & Doors

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.

We had Nex-Gen install our Infinity windows some time back was very pleased with the service and love the windows. We had hail damage on the lower trim and needed repairs called and set a date for the work, Mike showed up at the set time and went to work. Very professional in his time and work,
They look just like new once more. Great windows and even better service. The quality of Infinity and the service from Nex-Gen was the best.

Thank you Nex-Gen! Ted was knowledgeable and friendly with helping us select the right windows and patio door for our house. The installation team was professional, along with giving attention to every detail. The new windows have really made our house stand out in the neighborhood, with neighbors stopping by to let us know how great the windows look. Thank you!

I love having working windows in my vintage home.

The Nex-Gen team did an amazing job. Everyone was professional caring. I got all my windows and front door replaced. I love how it makes everything look so much better. My trailer is staying cooler in the hot weather. I can't wait tell winter to see how much better things will be with keeping the cold out. Thank you for doing an awesome Job

We would recommend this company! They replaced all the windows in our home and it was a very easy process, from the initial meeting with Ted, who was very helpful and knowledgeable, through the installation. The install team was very good at their job and went above and beyond for us. There was a couple of glitches during this process, but everything was handled in a timely and professional manner. We love our new windows and could not be happier with our decision to use Nex-Gen.

Ted Rajewski and his crew were extremely professional, courteous, with thorough attention to detail. Ted was very helpful with window custom plan and helped prioritize windows needing the most attention. We absolutely love the quality and look of the windows! The window awning hardware makes the management of the windows very easy, and the interior and exterior finish a great match for a custom home. We have begun phase two for continuing the window replacements and are looking forward to the improved comfort and energy efficiency which we immediately recognized with the first window project. We highly recommend NexGen Windows and Doors Ft. Collins!!!!

Fantastic work done by Nex-Gen. I did quite a but of research before purchasing and they had a great price for the work i wanted to get done. Workmanship was top notch and will use them again if i need to have some work done on the house!! Thank you!!

Nexgen did a great job with our window replacement. We replaced every window in our home down to the studs. The Marvin energy efficient windows are top notch and have been worth every penny.
