Nex-Gen Windows & Doors

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.

I had these guys install a sliding glass door. It was spring so couple weather glitches. They got the job done and their attention to detail was amazing. Great customer service. Always took care of any details that needed to be done. If I have any other window work that needs to be done I will be calling these guys.

A few years ago, Nex-Gen installed double-hung windows for our sunroom and it's really made the space so enjoyable. Good quality windows for a good value, and very professional service. It's made such a difference we've decided to use them again to replace our leaky aluminum basement windows with vinyl. Really looking forward to the improvement.

Ted did a great job helping us choose the right windows for our home in Johnstown. Wendy did a great job communicating installation dates, James and Dave did a great job with the installation. Good craftsmen that complemented the new windows and doors. Your first choice is to call Nex-Gen, they will follow up with your expectations.
