Nex-Gen Windows & Doors

Nex-Gen did a great job with my sliding glass door replacement. I chose the Everwood finish so we could match our previous oak decor. The Marvin glass door is very solid and looks great. I loved being able to inspect all the hardware in Nex-Gen's showroom before our purchase. The work was very professional and the price was very good. As with any company, it does pay to inspect the work while it is in progress. I was able to have them fix a nit-picky concern during the install.

A major hailstorm damaged all the windows in our home so we needed our wood casement windows replaced. We were dreading this major undertaking. But our experience was amazingly pleasant with NexGen from beginning to the end. Everyone was very knowledgeable and helpful and the installers were professional, polite, and very thoughtful in every way. Our Marvin Infinity Windows have passed the test in every way. We highly recommend NexGen!

We got half of our windows done a few years back and they are all very personable and efficient. Marvin windows are great quality. We are hiring them again for a few more. Ted is wonderful!

Friendly staff & great windows

I saw the great reviews this company had when I was first looking for new windows. Ted did not disappoint in explaining the product, and he gave me a good price. I highly recommend this company to anybody looking for windows.

We had to replace 3 very old windows in our home and chose Nex-Gen based on recommendation. The Nex-Gen team was very friendly, professional, and easy to work with. The windows are excellent quality and they took care to make sure that the job was done right.

We visited the Nex-Gen showroom in Fort Collins. The salesman was helpful and informative but not pushy. We had another salesman visit us at home and give us some ideas. He asked for our business but was not pushy. He understood that I was dealing with the death of my father, and also understood that we were in the middle of refinancing, and he and his supervisor worked with us in a patient and polite manner. When the windows arrived the efficient and polite crew did the installation in 2 days. A week later two painters arrived and carefully painted the inside framework for us. During a recent severe cold spell we noticed an improvement in how our house retains heat better and our north-facing windows no longer are cold. We also noticed that we don't hear as much vehicle noise as we did before. We are happy customers of Nex-Gen Windows in Fort Collins.

From the beginning of contacting Nex-Gen to finish of the project the process was smooth and without hassle. We had considered other brands but the Marvin windows with the fiberglass technology were the most superior and by far the best value from what we were quoted from other companies. Our window installers and finishers were professional and trustworthy. Our house is now more quiet, comfortable and safe! Ted and his team are great.

We had our home resided and installed new storm door and main entry door. From 1st appointment for estimate we were treated with respect and felt no pressure to to make a quick decision or pressure to buy. We learned a lot from Ted our salesman who saved us several thousand dollars by explaining that not everything had to be replaced. When we made our final decision and placed our order everything moved along very smoothly. Brent, the owner of the company was responsive to our questions and has a wonderful office staff to efficiently handle anything that might come up. Questions and calls were returned promptly. Delivery and installers we equally efficient. They worked hard only stopped for a short lunch break and worked from sun up until sundown. When the job was finished Brent and his foreman came out to do a walk around to be sure everything was done to our complete satisfaction....

We love the doors they installed! They look so elegant. I smile every time I walk by them. This was somewhat complicated as they had to shorten a 6 foot window above our front door. It looks better now then ever before. We received wonderful advice and help from Ted. I will definitely recommend this company to my friends and neighbors.
