Factors That Affect Garage Door Longevity

1. Material Quality

Steel: Durable and low-maintenance, ideal for long-term use.

Wood: Aesthetic but prone to warping and rot without proper care.

Fibreglass: Lightweight and resistant to rust but may crack over time.

Inspections: Check for wear and tear, such as frayed cables or loose hardware.

Cleaning: Remove dirt and debris to prevent corrosion.

3. Frequency of Use

High-traffic doors in busy households may experience faster wear.

Doors used as primary entrances often have shorter lifespans due to increased cycles.

Common Issues That Shorten Lifespan

1. Neglected Maintenance

Impact: Leads to rust, misalignment, and damaged components.

Solution: Schedule regular inspections and tune-ups.

2. Weather Exposure

Impact: Extreme temperatures, humidity, and UV rays can degrade materials.

Solution: Opt for weather-resistant finishes and insulate the garage.
