Garage Door Hinge Replacement
With the door closed and a flashlight on the inside face, one of the hinges near the edge has a crack running from the screw hole to the knuckle.
In plain words
A hinge visit runs in a settled order. The opener is disconnected and the door is left closed, because with the panels stacked on one another and the bottom resting on the floor, the hinges are carrying very little. The technician looks at every hinge on every joint and checks the rollers and the screw holes at the same time. Worn hinges are then changed one at a time so the door is never without a joint, each new part matching the number and gauge of the old. Then the door is run by hand, checked for a flush fit and balance, and the opener is reconnected and tested.
How the visit goesThe car nudged the door on the way in. There is a dent low on one end, and above it the hinge that carries the roller is bent so the panel edges rub together and squeal as the door lifts.

How the visit goes
The rollers the hinges carry
Each edge hinge cradles a roller stem, and the two wear together. The technician spins every wheel, looks for cracked or flat-spotted tires, checks that the stem has the right length for the hinge it sits in and that the bearing turns without grinding. A roller that has seized drags at the hinge on every trip, and a stem that is too short lets the wheel wander out of the track and twist the hinge. Where rollers are worn, changing them while the hinge is off costs a few minutes and stops the new hinge inheriting the strain that finished the old one.
The right number, gauge and pattern
Every replacement hinge is matched three ways. The number matches the joint, read from the old hinge or counted from the floor, so the roller sits at the correct offset. The gauge matches or improves on the original: 18 for a light door, 14 for the heavier residential standard, and thicker still where a heavy insulated door or heavy use calls for it. The width and hole pattern match the stile, since a hinge from one maker may not line up with another's panels. Where the door has a mix of numbers from earlier repairs, the technician corrects them so all edge hinges follow the proper sequence.
Lubricating the knuckles twice a year
Hinges want a light film of lubricant on the pin where the two leaves meet. Spring and autumn are the natural moments. Use a silicone or white lithium spray made for garage doors, put a short burst on each hinge knuckle and on the roller stems, then run the door a few times to spread it. Heavy grease or general oil holds grit and salt against the steel, so it is avoided. Leave the track itself dry and simply wipe it clean, since lubricant there collects dirt and lets the wheels slide. Ten hinges take about as long as making a coffee.

What affects the quote
Opener adjustment afterwards
A door that folds freely again sometimes needs the opener's force and travel settings reset and its reversal retested. That adjustment is named when it is needed.
Damage to the stile or panel
After an impact, straightening a stile, fitting a support plate or adding a strut comes with the hinge work and is quoted as separate items so you can see each one.
How many hinges are changed
One cracked centre hinge is the smallest job. Several worn hinges across two or three joints, which is common on an older door, means more parts and more time, and the quote lists each.
What to have ready
- Is the door a single or a double, and how many panels does it have?
- Is a roller leaning or partly out of the track anywhere?
- Is the loose or broken hinge at the edge of the door or in the middle?
Garage Door Hinge Replacement: questions
QuestionsWhat do the numbers stamped on garage door hinges mean?
They mark the joint the hinge belongs to, counted from the bottom. A 1 goes at the joint above the bottom panel, a 2 at the next one up, then 3, with 4 and 5 on taller doors. Each higher number stands the roller a little further off the door face, so the door leans into the jambs when closed and follows the track as it climbs. Centre hinges use the geometry of a 1.
Can any hinge go in any position?
Edge hinges belong to their own joint. Put a 3 where a 2 belongs and the roller sits at the wrong reach, so the door binds, gaps at the curve or fails to press against the jamb when closed. Centre hinges are the exception, since they all share the geometry of a 1. The technician reads the stamp on the old hinge or counts the joint from the floor before choosing the part.
What gauge of hinge does my door need?
Gauge runs backwards: a larger number means thinner steel. Light single doors often come with 18-gauge hinges, 14-gauge is the heavier standard for most residential doors, and 11-gauge is commercial stock. A heavy insulated double door, a door used many times a day, or a door whose hinges keep cracking benefits from the thicker option. The technician matches or improves on what was fitted, provided the width and hole pattern suit the stiles.
