Put off a decision about garage door windows for one more season and here's what it costs you: another winter of rain-dark mornings fumbling for a light switch, another summer of a garage that bakes because the wrong glass let in heat you didn't want, or worse, a door that quietly broadcasts to anyone walking by whether your car is home. Windows change how a garage door performs every single day, not just how it looks from the street. If you're planning a new door or replacing panels, now is the time to get this right, before installers book up for spring.
