Nex-Gen Windows & Doors

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

Love my new windows, installation was a breeze, awesome people to work with beautiful wood finish, the windows are almost as pretty as the outside views! Thanks all!

A few months ago I researched different companies for our HOA because several neighbors had said they wanted to replace some or all of their windows. Of the four companies I checked, Nex-Gen was the one we all chose. Ted is great, friendly and knowledgeable and helpful. He has done work here for several residents. And now he's helping me too. I'm very happy working with Ted and I know I'll be happy with the windows that he'll have installed in my home!

Glad we choose Next Gen! We had some of the other major companies come out and give us estimates. They seemed ok with decent prices, but we didn't get that feeling like they really wanted our business and they were just doing there job.

Then we saw the reviews for Next Gen and gave them a call. We can't say enough good things about Ted the sales rep who explained everything really well to us and treated is like an old friend. It was great with none of the pressure sales that the other companies used, like if you don't sign up you would be missing out on some amazing deal! He simply showed us his windows, talked about the company and gave us a better price than the competitors. I liked the windows better than the other ones that we were shown from the other companies. He literally could have just set the sample window down and we would have been sold. It just looks like a...

We researched our basement replacement window project exhaustively and decided on the Marvin Infinity product and Nex Gen as the installer. We've had our windows now for 5 years and couldn't be happier. Ted is excellent to work with to get an idea of cost and the design of the project while Brent and the installers provide a high end finished product. Nex Gen stands behind their product as well with an excellent warranty and responsive service should anything go wrong with your windows down the line. We're getting going on another window project currently and will eventually replace all the windows in our home with Marvin Infinity through Nex Gen. Nex Gen is a reliable company providing a high quality long term product at a competitive price.

Great Job!! Would definitely use again.

Pre-Contract Assistance

Window and door replacement is a daunting experience. One has to select both products and installers. Nex-Gen provided excellent guidance and patiently answered all of our questions. A visit to their showroom was extremely helpful, as were their online videos.

Installation

This was an outstanding contractor experience. Nex-Gen affirmed its commitment to excellence in every stage of the project.

They were exceptionally careful about the quality of the installation and equally careful about avoiding damage to our home during the installation which is under any circumstances a major and disruptive construction project.

The materials and craftsmanship of the interior wood finish is spectacular; the window and door frames look like fine cabinet...

I replaced the majority of my windows and a patio door. I chose Nex-Gen because of the quality and warranty on the windows. Everyone from sales to installation was great to work with. I had a minor repair on a window latch and it was taken care of right of way. I love the windows. When I finish replacing the last of my windows I will definitely return to Nex-Gen.

We had our patio door replaced with an Infinity Sliding Patio Door with Everwood interior finish. Our interior has oak woodwork and they custom matched the stain on the interior Everwood material. I am amazed how energy efficient the door is. The door is located in our kitchen and it is so comfortable to be sitting near the door both in the winter and summer.

I highly recommend Nex-Gen Windows and Doors out of Loveland, CO.

Me gen is back again. We had some windows and a glider replaced. They did such a wonderful job that when recent hail storm damaged other windows (NOT theirs!) we had them come out to replace some more. Ted is wonderful - carefully explains and clearly informs. Brent is an ultimate professional. Highly recommend.
