Your garage door opens and closes maybe 1,500 times a year. That’s 1,500 chances for a spring to stretch, a roller to wear, or a cable to fray. Most failures don’t happen out of nowhere — they happen after months of warning signs you didn’t notice.
This 5-minute check catches most of those signs. Do it once when the clocks change in spring and again in fall. No tools, no greasy hands.
The check
- Watch and listen as it opens. Stand in the garage and run the door through one full cycle. You’re listening for grinding, screeching, or sudden bangs. A normal door is loud-ish but smooth. A door that’s about to fail makes new noises.
- Look at the springs. Above the door, you’ll see one or two torsion springs wrapped around a shaft. Any gaps in the coil, any rust, any visible bend in the shaft — make a note. Springs are the #1 part I replace.
- Pull the red cord. That’s your emergency release. Pull it with the door closed, then try to lift the door by hand. It should glide up smoothly and stay open chest-high. If it crashes back down or you can barely budge it, the springs are out of balance.
- Check the rollers. Open the door fully. Look at the small wheels rolling in the tracks on each side. If they’re cracked, flat-spotted, or making the track jump, they’re done. Nylon rollers are cheap and quiet. Steel rollers are loud and wear out faster.
- Wiggle the bottom seal. That rubber gasket at the bottom of the door keeps water, dust, and lizards out. If it’s torn or flattened, you’ve already lost the seal.
- Test the sensors. With the door open, hit the close button and wave a broom through the photo-eye beam down by the floor. The door should reverse immediately. If it doesn’t, the sensors aren’t doing their job.
- Reset the emergency release. Pull the cord toward the door and lift until you hear it click back into the trolley. Run the opener once to confirm it re-engages.
What you’re looking for
The early-warning signs I see most:
- Uneven opening. One side higher than the other means a cable, a spring, or a drum is failing.
- The door drifts back down on its own. Spring tension is gone. It’s a matter of weeks before something snaps.
- Grinding at the top of travel. Usually a worn roller hitting the track curve.
- Slack cable. Should be snug like a guitar string. If it’s loose, it’s about to jump off the drum.
If you spot any of these, don’t wait for it to fail on a Sunday night.
When to call
This is a 60-second job: take a video of whatever’s wrong, text it to me, and I’ll tell you if it can wait or if I should come out. No charge for that.
Twice-a-year inspection saves you the $150 weekend-emergency surcharge. Set a calendar reminder for daylight saving — it’s the easiest one to remember.
Doors don’t fail dramatically. They fail slowly until they fail completely. Five minutes twice a year keeps you on the slow side of that curve.
