Andersen is regarded as a market leader. Their master casement window was a key industry first when it was launched in 1932. It was the first fully built window in the business, and it set a standard right away.

Another element that sets Andersen apart from its competitors is its dedication to producing high-quality energy-efficient windows while remaining environmentally conscious. The company has implemented environmental programs to lessen its environmental effect. They also intend to increase the quantity of renewable energy used in their facilities.

Frequently Asked Questions

What is a Limited Lifetime Window Warranty?

One of the most popular warranties offered by replacement window providers is a limited lifetime warranty. A limited lifetime guarantee covers defects in the aesthetics and performance of your window.

Note that a limited lifetime guarantee may only cover replacement parts and not window repair labor. This means the manufacturer will cover replacement parts like sashes.

You may have to pay to have the window physically repaired by the manufacturer. Replacement window manufacturers, however, have different procedures. Make certain to inquire further with your sales agent.

Does Warranty Apply if You Install Your Products?

When you opt to install the products yourself, it is critical to inquire about warranty coverage with your window dealer. While some warranties will still cover self-installation, the majority will not. This is one of the most significant disadvantages of installing exterior remodeling products yourself.
