What You Should Look for in Replacement Window Warranties

When having replacement windows installed in your home, it’s important that you look over the warranties that come with the product. After all, if your window is damaged earlier than expected, you can have it repaired or replaced at no cost. Which is why it’s important that you examine the warranty as closely as possible.

What You Should Look for in Replacement Window Warranties

In this post, Renewal by Andersen® of Des Moines discusses what you should look for in a window warranty.

Product Warranty

A product warranty is provided by the manufacturer and offers coverage for manufacturing defects. While it won’t include items, such as damage from abuse and failure to do maintenance, it will cover any replacement parts needed due to manufacturer defects like failed glass seals, defective hardware and other issues. If you plan on selling your home soon, ensure that the warranty is transferable. Be on the lookout for proration as well.

Renewal by Andersen’s product warranties will repair or replace any defective parts on your window or door at no cost for you. Our limited warranty lasts up to 20 years from the original installation date. However, keep in mind that slight glass curvature, minor scratches and other glass imperfections are not covered by the warranty.

Installation Warranty

The installation warranty on your replacement windows vary from one dealer to the other; one dealer may offer a one-year installation warranty while the other may offer a lifetime warranty. Installation issues tend to manifest visually within 1 or 2 years so always choose a 5 or 10 year, or even a lifetime, warranty if possible. These warranties are meant to cover any poor or defective installation practices so maintenance issues like caulking are not covered.

Renewal by Andersen’s installation warranties cover a 10-year period from the original installation and can be replaced or repaired at no cost to you. This limited warranty doesn’t extend to any services performed by anyone other than the original installers.
