Garage doors can last for many years; up to 15 years is common. Minor damage can call for a few repairs. Still, some damage can lead to more significant damage over time if not repaired correctly. A replacement may be necessary if your door will not open or close, is hazardous to the home, or causes excessive noise and vibration. Structural damage, such as wear and tear on multiple panels, can lead to a needed replacement. If your repair cost looks similar to a replacement cost, consider replacing your garage door.
