The seal failed on one of my windows - how do I actually make a warranty claim?

Start by locating your original purchase documentation and warranty paperwork - this will have the manufacturer information and warranty terms you'll need for your claim.

Most window seal failures are covered under manufacturer warranties, typically ranging from 10-20 years for insulated glass units. The warranty usually covers the sealed glass unit replacement, though labor costs may or may not be included depending on your specific warranty terms. You'll need to identify the window manufacturer (often found on a label in the window frame corner or spacer bar between glass panes) and contact them directly or through your original installer.

If you know who installed your windows, start with them - the installer who did the work is normally the one who files the claim with the manufacturer on your behalf. For windows installed by other contractors, you can either contact the installer who should facilitate the warranty process, or reach out to the manufacturer directly through their customer service department.

The warranty claim process typically involves submitting photos of the failed seal (showing fogging or condensation between panes), providing proof of purchase, and scheduling an inspection if required. Most manufacturers will send a replacement sealed glass unit to your installer rather than directly to homeowners, since proper installation requires specific tools and techniques.

In Ottawa's climate, seal failures often occur due to extreme temperature fluctuations, and quality manufacturers understand this is a common warranty issue. Keep in mind that if your windows are beyond the warranty period, replacement of just the sealed glass unit is usually more cost-effective than full window replacement.

If you cannot locate your warranty paperwork, or the original installer is no longer trading, request a quote through Ottawa Window Pros and ask an installer what your options are and what the most cost-effective repair would be.
