Whether you’re moving into a new property or considering adding new windows to your current home, it’s important to evaluate the quality and lifespan of your windows. Most window manufacturers offer comprehensive warranties on their products, and so homeowners across the country should establish the type of warranty they require for their window systems.

In this article, we’ll look at four ways to evaluate the lifespan of residential windows

Consider the Meaning of “Lifetime Warranty”
When buying new products for your home, it’s important to analyze what the company considers a lifetime warranty. While this generally refers to a warranty that covers the full lifetime of the product, some vinyl windows might only be covered for 25 years. For those that have owned their home for 25 years or more, this could mean they must pay to replace their current vinyl windows.
Review Installation Warranty Documentation
The installation warranty is usually provided when you buy the windows. However, the contract may also be connected with the installation firm. It’s important for you to analyze the length of the installation warranty and determine whether it fits your expectations. Most companies offer a 1-year installation warranty, which enables you to call the company back when a defect occurs or is seen within 1 year of the installation work.
Is the Warranty Prorated or Non Prorated?
When examining the lifespan for your residential windows, it’s also important to consider whether your warranty is prorated or non prorated.

A pro-rated warranty requires you to pay a fee for any work on the windows in the future. This fee will increase as time passes. Non pro-rated window warranties mean that the entire fee for repair or replacement is then covered by the warranty. However, some installation costs may not be covered by the non prorated warranty.
Is the Warranty Transferable?
When it comes time to sell your home, you’ll want to know whether the window warranty can be handed over to the new owner. This means you should speak with the manufacturer and installer about whether the warranty for your windows is transferable. Having a home with warranty-covered windows could be seen as a critical advantage in your local real estate marketplace.

By analyzing the various warranty options when integrating new windows, you can ensure you make the ideal decision for your long-term future. To learn more, speak with our expert team today.
