The Andersen Windows and Doors Corporation was incorporated slightly over a century ago. Over the years, the company has redefined industrial trends and practices, working its way to the top as America’s premier window manufacturer.

For homeowners looking to replace their windows, Andersen offers an array of products to choose from. Before settling on one for your home, there are several factors to consider, such as the state of your home’s existing window frames. Most Andersen replacement windows are full-frame or insert windows. If your original frames are intact, you can go for the insert windows option. The full-frame option is ideal if your existing frame is rotted or deteriorated.

In this guide, we discuss the best Andersen replacement windows, reviewing their features, prices, and warranty information to help you choose the best option for your needs.

What Makes the Best Andersen Replacement Windows?

Replacing old windows with modern, energy-efficient models can pay off financially and aesthetically. Here are some of the primary factors to consider when comparing Andersen replacement window options:


Andersen Replacement Windows are priced by frame. Full-frame replacement windows are more expensive compared to insert windows, which are inserted into existing window frames.

Customer reviews

Customer reviews offer firsthand information on the efficiency of a specific window and its performance over time. This information enables you to make an educated decision on the ideal window for your living space.

Customer support

Any reputable window manufacturing company will take time to guide you through the different makes of their windows so that you can make an informed decision. They should also have favorable warranty options on all their products.

Advanced features and design

Consider the frame of the specific window you want to buy. While window frames influence their thermal characteristics, they also determine factors such as durability and weight. Wood frames offer superior aesthetic value but require extra maintenance during their lifetime. Aluminum window frames are strong, light, and inexpensive compared to wooden frames. Vinyl window frames are ideal if you want a low-maintenance option, while fiberglass composite frames are excellent in extreme weather conditions.

With respect to design, you can choose from double-hung or single-hung windows. Single-hung windows feature a stationary top sash, while double-hung windows allow you to move both sashes up and down. You can also opt for a casement design, which is hinged like a door and usually opens from the side. Other options include sliding, arched, rotating, and bow designs.

Industry awards and certifications

Excellent manufacturers are often recognized with industrial awards, such as the Energy Star Awards. In 2019, Andersen Windows and Doors won the “Energy Star Partner of the Year Sustained Excellence Award” for their commitment to making energy-efficient products.
