Why won’t your garage door close properly?

A garage door that doesn’t close properly can pose a safety and insulation problem. There are many possible causes, from simple misalignment to more serious mechanical problems. Identifying the source of the problem is essential to carrying out an effective repair and avoiding a worsening of the situation.

Check alignment of rails and castors

If your garage door doesn’t slide smoothly or jams before closing completely, the tracks may be out of alignment.

• Inspect rails for deformation or obstructions (dirt, small objects).
• Tighten screws and fasteners if you notice any abnormal play.
• Lubricate castors and rails to facilitate movement and prevent squeaking.

Check springs and cables

Springs and cables play an essential role in balancing the door.

• Loose or broken springs: If the door jams or drops suddenly, the springs may be to blame. We recommend that you call in a professional to replace them, as they are under high voltage.
• Worn or frayed cables: Damaged cables must be replaced to prevent the door from jamming or derailing.

Test safety sensors (for motorized doors)

Motorized garage doors are equipped with safety sensors that prevent closing in the event of an obstacle.

• Clean the photoelectric cells to prevent dust or cobwebs from interfering with the signal.
• Check their alignment: if the sensors are out of alignment, the door will remain open for safety reasons.

Check motorization and settings

A motor problem can also prevent the door from closing completely.

• Check remote control and control system to rule out battery failure.
• Reset the motor following the manufacturer’s instructions to recalibrate the opening and closing settings.
• Make sure that the closing force is correctly adjusted, as too low a setting may prevent the door from lowering completely.

Inspect seals

A worn or incorrectly positioned gasket can prevent the door from closing completely.

• Replace the bottom seal if you notice excessive wear.
• Adjust the fasteners if the seal is misaligned and prevents the door from closing tightly.

When to call in a professional?

If, despite these checks, your garage door still doesn’t close properly, it’s best to contact an expert. A poorly executed repair can aggravate the problem, leading to safety hazards or total failure.
