Understanding Your Replacement Windows Warranty

For some homeowners, a window replacement may not be the most costly home remodeling project. However, it can still be an important investment. For this reason, you might want to consider getting a solid warranty to ensure your windows installation goes seamlessly.

 Replacement Windows Warranty

Before the work begins, make sure that you understand how your replacement window warranty works.

Length of Warranty Coverage

When it comes to the length of your warranty, there are three types you should know about: lifetime warranties, limited lifetime warranties and timeframe warranties. Lifetime warranties can cover your windows as long as they are subject to wear and tear. Meanwhile, limited lifetime warranties cover specific defect types and may not include the cost of labor to fix the issue. As for time frame warranties, they usually expire after a set number of years. 

Additionally, the length of your warranty will often vary for different components of the window. As such, you have to read your contract carefully and understand the exact coverage time for each window component. 

Components Covered by Warranty 

The components covered by your warranty may vary as well, but the following are generally expected to be covered under the limited lifetime warranty. Window materials that have been damaged within the designated time frame can be covered under warranty. One example of window material coverage is vinyl extrusions in your window frame.

Malfunctioning hardware can also be repaired or replaced under the warranty as long as it falls within the period. If you have energy-efficient windows, they can also be covered by your warranty. Inert gases are designed to last many years inside of your windows, but there are some cases wherein they can deplete at a much faster rate. 

When replacing your windows, you should hire professional window installers. This is because you might void your warranty should you attempt to install replacement windows on your own. If your new windows include upgrades, such as custom glass designs, etched glass or grids, any defects found in these products can also be covered by your warranty.

Transferable Warranty

If you sell or move out of your house before your warranty expires, you should ask your insurer about the transfer of the warranty. There are instances wherein the warranty will be void, but transferable warranties may allow you to pass on the warranty to the next owner of your house. It’s also important to note that investing in a transferable warranty can add value to your home if you plan to sell it.

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
