Nex-Gen Windows & Doors

I really cant say enough about the entire experience. Especially in these most recent time's we are all going through.
Starting with Hunter taking my initial call, then Ted coming out to the house and helping with my decision making. Windy keeping me in the loop during the manufacturing process and finally, exactly on time meeting the installation crew, Ishwa and Drew.
Everyone treated me as if we had know each other for years. The job is A++ and they all let it be known that they will be here for me in the future when and if needed.
Thank you all for reminding me that the " American work Ethic " is alive and well on our Front Range.

Superior service, installation, and product. Nex-Gen did a full window replacement on our two story home in Fort Collins on October 2020. Two months later, everything is still perfect about them. We chose many different window types for the house (double hung, awning, casement, half moon, sliders, oriels) and changed our minds several times through the design process including adding two new window openings. The thing that impressed us most about Nex-Gen was their patience through our design changes and that they ordered everything exactly right in the end. We met with 5 other window replacement companies to get bids. We ended up going with Nex-Gen due to their full frame installation (vs pocket) and the fiber glass Marvin windows having a slimmer profile and better heat tolerance for direct sunlight. We were really glad we went with Nex-Gen once the design process started...

Ted and the installers provided windows for us in our bedroom two years ago and we were so impressed with the quality of the windows and installation. Now two years later, Susie and I loved the quietness, the warmth in the wintertime, insulation from heat in summer and ease of cleaning of the windows that they installed. We are looking forward to having them now install windows in our dining room and a new French Door in our MBR this winter. Just a great company with consistently good people.

Had a great experience, love the windows.

Nex Gen replaced 6 windows in our 30 year old house and we couldn't be happier. Thier communication was top notch and they delivered when they said they would. The installers were courteous and professional and did a great job. I am an extremely picky person but can honestly say I found absolutely nothing wrong with their quality of work. Once finished they cleaned up so well you couldn't even tell they had been here other than seeing new windows. The painters also did an excellent job painting the new interior and exterior trims and cleaning up. If you are looking for quality windows, not big box store windows, Nex Gen is the way to go.

Great company, great service, great pricing. They've replaced 11 windows over the last 2 years, we are very happy with Nex-Gen windows!

We had our upstairs windows replaced by NextGen Windows and Doors and now we’re having some downstairs windows and slider replaced. Very pleased with quality and professionalism of all so we wouldn’t consider using anyone else. Thanks to Ted and His team and Infinity from Marvin fiberglass windows.

We had such an spectacular experience with Nex-Gen with our Window replacement a couple years ago that we didn't bother looking elsewhere when it came time to replace our back door. Just like before, our sales rep was informative, polite and friendly, plus the price was right in line with what we expected. Thanks again Nex-Gen for doing a great job and making everything amazingly simple and easy!

I really liked how they follow up with their beautiful product. Windows and doors work WELL and keeps my home more quiet. Ted and his team continue to check to make sure I have been happy with their work. Thank you for this service of the Infinity from Marvin Windows and Doors!
