Don’t Void Your Window Warranty: 6 Common Issues You Can Avoid

An excellent warranty can be a great selling point when you’re choosing new replacement windows. And, of course, you want your investment in your home to be protected. But if you ever need to file a claim, you’ll want to make sure that you or your window replacement contractor haven’t done anything that will void the manufacturer’s warranty.


There are actually two types of warranties for replacement windows, workmanship warranties that cover the contractor’s work and manufacturer’s warranties that cover the physical products being installed.

There are quite a few ways to not void a manufacturer’s warranty. While every warranty has its own specifications that your contractor should be able to discuss with you, here are six things that will likely void any window manufacturer’s warranty.

1. Improper Installation

Most window warranties are specific about how the product should be installed. A common way that window manufacturer’s warranties are voided is through unprofessional or inexperienced installation. To avoid improper installation that leads to a voided warranty, check to see if your contractor is licensed and if they are an authorized dealer for the window brands they install.

2. Incorrect Use

Most windows are straightforward to open and close, but it’s still a good idea to ask your installer to show you how to use the window properly. Many new windows can swing out and tilt for easy cleaning, but this may take a few steps. And window locks should be relatively easy to slide into place, so if you find yourself jamming them, you could be damaging the locking mechanism.

3. Installing Blinds or Locks

Any time you are applying an aftermarket product to something in your home, you are in jeopardy of voiding the warranty. Because many blind brackets and locks require drilling or screwing into the window frame, they can void your warranty. They also commonly damage the mechanical parts of the window that support the weight of the bottom sash when open. Additionally, they can reduce the window’s energy efficiency. Consult the window manufacturer first to see if certain after-market accessories will void your warranty.

4. Adding Window Film

Another aftermarket product, window film, can also void your warranty. This is because window film can cause damage to the glass. However, some window films will replace the window manufacturer’s warranty. But they likely need to be installed by a professional, so it’s always a good idea to bring up warranties with your contractor.

5. Improper Maintenance

Window maintenance is relatively easy, just removing dust and dirt with a damp soapy cloth. But if you don’t keep your windows in good condition, it could void your warranty. This is especially true for wood windows, which can quickly fall into disrepair if they are not well maintained.

6. New Ownership

Some warranties only cover the original owner who paid for the windows to be installed. In this case, there’s not much the new homeowner can do. However, other warranties simply require that the new owner notify the manufacturer within a specified time period, usually around 30 to 90 days after the purchase of the home. Don’t miss out on a warranty offer by merely failing to let the manufacturer know that you are the new homeowner.

While the issues above are common, every warranty is unique. So, make sure you look over your warranty carefully before signing a contract with a window installer. They should be familiar with the manufacturer’s warranty and able to provide you with the manufacturer’s contact information to answer any questions you may have.
