What to Look for in a Window Warranty
Begin By Checking The Core Coverage A window warranty is only useful if you know what it protects and for how long. Most homeowners look at a big number like "lifetime" and stop there. Those are the pieces most likely to show wear or fail in the field. Still, you want to see whether the warranty covers replacement glass only or the full unit, and whether labor is included. Frame and sash coverage matters just as much, especially on vinyl vs fiberglass windows
