Superior Products

There are several factors to consider when selecting new windows – materials, durability, efficiency, and maintenance, just to name a few. Here in Colorado, where hail and other bad weather are common, it’s important to be prepared. Here in Colorado, where we often have extreme weather and hail, it’s important to buy something that will last. 

That’s why we’re so proud of our Anlin replacement windows. Our windows come with a warranty that extends as long as you own your home – something that’s not offered by many other window manufacturers. So if you’re looking for a window replacement in Colorado, be sure to give us a call. We know you won’t be disappointed.

Along with an extended warranty, here’s what you can expect from your new Anlin windows: 


While many build their businesses solely on the reputation of the products they provide, we at Nex-Gen Windows and Doors understand that the effectiveness of your windows relies on more than just the windows themselves. 

It is estimated that

65% of service-related issues involving prematurely failed windows are related to improper installation

This means that you could unknowingly invest in quality windows only to find that the installation was less than effective, therefore significantly lowering the life of your windows and your return on investment. 


We’ve heard countless stories of competitors who installed windows using shortcuts, caused unnecessary damages, or left a mess behind.

Our job is not over until your windows are properly installed, your space is properly cleaned, and you confirm that we have met or exceeded your expectations.
