Simple monthly and annual steps that extend door life and catch problems early.
A well-maintained garage door operates quietly, lasts longer, and is less likely to fail at the worst possible time. Most of what homeowners can do safely is visual and preventive. The mechanical adjustments — spring tension, cable tension, opener force settings — should be left to a professional.
Use a silicone-based garage door lubricant or lithium grease spray — not WD-40, which is a solvent/cleaner that removes lubrication rather than adding it.
Apply to:
Wipe off any excess. The goal is a thin film, not dripping lubricant that attracts dust.
Disconnect the opener (pull the red emergency cord), manually lift the door to about waist height, and release it. A properly balanced door stays in place or drifts slowly. A door that slams down or flies up is out of balance — the spring tension needs adjustment. This is a professional repair.
Place a 2×4 flat on the ground in the door's path. Close the door using the opener. When the door contacts the board, it should reverse immediately. If it doesn't, the opener's force limit needs adjustment — a professional can calibrate this. This is a safety feature required by federal code on openers manufactured after 1993.
Anything involving spring tension, cable tension, or opener force adjustment is professional territory. If you notice the door feels heavier than normal, one side is lower than the other, or the opener strains, call for a tune-up before those signs become a failure.
Open Sesame offers full tune-up service starting at $100 — 314-897-4721.
Twice a year is the standard recommendation — spring and fall are good timing given Missouri's temperature swings. If the door starts making noise, don't wait for the schedule.
No. WD-40 is a water displacer and degreaser, not a lubricant. It will temporarily quiet a noisy door but strips the existing lubrication and attracts dust. Use a dedicated garage door lubricant spray or white lithium grease instead.
Grinding usually comes from rollers (worn bearings), hinges (dry metal-on-metal), or the opener drive chain/belt (insufficient lubrication or chain stretch). If lubrication doesn't resolve it within a day or two, the component likely needs replacement.
With the door open, wave your hand through the sensor beam while pressing the close button. The door should stop and reverse. If it doesn't, check that the sensors are aligned (the lights on both sensor units should be solid, not blinking) and that nothing is blocking the beam.
