Tracks guide the wheels and keep the door moving smoothly up and down. Over time, tracks can develop bends or dents and need straightening or replacing. Check tracks annually for issues. Lubricate rollers and tracks as needed.


Rollers are wheel-like components that ride along the tracks. Replace rollers if they look excessively worn down or no longer spin freely. Check rollers every 6-12 months and lubricate.


Hinges connect door sections and allow them to fold up compactly. Inspect hinges annually for looseness, rust, or other defects. Tighten or replace as needed.


Springs provide the lifting power and are under high tension. Replace springs every 3-5 years or if one breaks. Left unreplaced, springs can snap with force.


Cables connect the door to the opener or manual mechanisms. Inspect cables yearly for fraying. Replace immediately if frayed to avoid snapping.


Panels are the sections that make up the door. Inspect panels for cracks, dents, or other damage yearly. Replace panels as needed to maintain structural integrity.


Weatherstripping seals the door perimeter to prevent air and moisture infiltration. Replace if cracked, peeling, or no longer creating a tight seal.

Understanding which Garage Door Components require regular inspection and maintenance helps avoid costly repairs down the road. With biannual lubrication and inspections of key parts, your garage door will operate smoothly for many years to come.


How often should I lubricate my garage door?

Most garage door experts recommend lubricating all moving parts (tracks, rollers, hinges, etc.) at least twice per year in spring and fall. This helps reduce noise and keeps components moving smoothly.

How can I tell when it’s time to replace my garage door opener?

Signs it’s nearing end of life include the motor running loudly, needing frequent repairs, not responding reliably to remote controls. Most openers last 10-15 years with normal use. Replace if over 15 years old.
