Garage door hinges connect the door's panels and let them fold as the door curves up onto the horizontal track. On many sectional doors, numbered end hinges set the roller offset. Center hinges often use number 1 at every panel joint. Match the door manufacturer's hinge layout, not a number based only on height.
Why hinges are numbered
On common standard-lift doors, number 1 end hinges join the bottom and second sections, with higher offsets above to match the track's taper. Some door designs repeat a number or use special hinges. Center hinges generally do not carry rollers. Match the part number, offset, gauge and hole pattern in the door's parts diagram; the wrong hinge can make it bind.
Materials
Galvanized steel is common. Steel gauge, offset and fastener pattern must match the door; a decorative or general-purpose hinge is not a substitute.
Signs a hinge needs replacing
- A metal-on-metal creak or bang at the same point in the cycle.
- A visible crack, bend or heavy rust on the hinge plate.
- Sections that no longer line up as the door moves.
Can you replace one yourself?
Have a technician replace damaged hinges. They connect and support heavy sections; removing hardware without securing the door can let a section shift. Never remove the bottom brackets that anchor the lift cables. For a parts inquiry, provide the door model and a photograph of the hinge markings without loosening it.
What it costs
Hinge replacement cost depends on the correct hinge model and gauge, how many have failed, labor and any roller or section damage. Ask for a written installed quote rather than comparing parts alone.
