Nex-Gen Windows & Doors

The greatest company we’ve ever worked with. Ted was awesome! The infinity widows made the house!!!

Nex-Gen replaced 7 old aluminum windows with new vinyl windows for us. The work included replacing old cracked composite window sills with wooden sills. The installation team did fantastic work- the new windows and sills looked and fit perfect. The windows were installed 4 years ago, and despite unshaded west facing sun exposure they still look and perform great today.

I would use Nex-Gen again.

Brent helped us choose the best windows for our home and the look we wanted. We wanted the windows to blend with our house and to last, so we selected Infinity EverWood. Brent chose a stain that matches the wood in our house and no visitor has done other than rave about how beautiful the windows look. Brent and his team installed all the windows (20 +) in our house and did a wonderful job.

The team was respectful, professional, and friendly during the installation, keeping our house as clean as possible and making the disruption as easy as it could be. The installation went smoothly and the windows are solid, draft-free, and gorgeous.

The installation was seven years ago and the windows look and perform as if they were new. We are exceedingly happy that we went with Nex-Gen and Infinity!

We decided to replace 14 year old vinyl windows in the entire house. Went to Nex-Gen after receiving an unsolicited recommendation. Ted promptly came to the house and gave us an estimate. Contract was made and after only 40 days received the date for install. Install team was careful and professional. Had a slight problem with a difficult bay window but Rick May came right out and corrected the problem, calling back and doing what he said he would do. That reliability was very important to us. We feel assured that should anything else present itself we can call Nex-Gen and they will follow up with us.

Great people!!! Great windows!! Love the showroom

A few years ago, Nex-Gen replaced all our windows and slider doors in our Namaqua Hills home west of Loveland.
The total was 19 windows and 5 sliders.

Excellent products and expert installation. No problems so far and we are very satisfied with the result. Great people.

Only 4 weeks from time of order to installation, minor problem with installation was corrected next day.

Would use them again

This review is actually from Beulah Buis, my mother. She had Nex-Gen put new windows on both her house in Fort Collins, and a rental house in Loveland. She loves the product and work they did at both places. She got hail recently on her house in Fort Collins and called them to check for damage. Ted came within 4 days to check everything out. She would definitely recommend this company to anyone who owns a house.

The people and products at Nex-Gen are awesome. They have replaced our windows and patio door. The customer service has been great and we've been really happy with the quality and looks of our Infinity from Marvin windows and french doors. I highly recommend this Nex-Gen.

Had nex-gen replace my 70s era windows recently. They were great to work with throughout the process, did a great job installing the Marvin windows and offered good pricing. I would recommend these guys for sure
