What Skipping This Costs You
After a dry inland summer, most garage doors in Pomona are carrying a fine layer of dust, pollen, and sometimes wildfire ash in the tracks and on the rollers. On its own, that grit is a nuisance. Once winter rain starts mixing with it, that dust turns into a gritty paste that grinds down rollers, eats through lubricant, and forces the opener motor to work harder every time it lifts the door. Skip the seasonal check now and the typical outcome by January is a door that's noisy, slow, or stuck halfway — usually traced back to worn rollers, a dry track, or an opener that's been straining for months. A $15 tube of lubricant and twenty minutes today is a lot cheaper than a service call for a seized roller or a burned-out opener motor later.
Tools You'll Need
- Sturdy stepladder
- Flashlight
- Silicone-based garage door lubricant (not WD-40 or household grease, which attract dust)
- Clean rags
- Soft brush or vacuum with a crevice attachment
- Socket wrench or screwdriver set
- A 2x4 or a roll of paper towels (for the safety test)
The Routine, Step by Step
- Look at the tracks. With the door closed, run your flashlight along both vertical tracks. You're checking for dust buildup, dried grime, and any dents or spots where the track isn't perfectly straight.
- Wipe the tracks clean. Use a rag to remove dust and residue before you lubricate anything — lubricating over grime just creates sludge that attracts more dirt.
- Check the rollers. Look for cracks, flat spots, or chips, especially if they're the original nylon rollers. Rollers wear unevenly, so check all of them, not just the ones you can see from the ground.
- Lubricate rollers, hinges, and springs' end coils. A light coat of silicone-based lubricant on moving metal parts reduces friction and noise without collecting dust the way grease does. Don't spray the actual track surface — rollers need traction, not slip.
- Snug up visible hardware. Garage doors flex every time they open and close, and bolts on hinges and brackets work loose over a season. A quarter-turn with a socket wrench on anything visibly loose is usually enough — don't overtighten.
- Test the auto-reverse safety feature. Place the 2x4 or a roll of paper towels on the ground where the door would close, and run the door down. It should reverse immediately on contact. If it doesn't, stop using the opener until that's fixed.
- Check the weatherstripping. Run your hand along the rubber seal at the bottom of the door and the vinyl strips along the sides. Cracked, flattened, or gapping weatherstripping lets water in once the rain starts, which can lead to a damp garage floor or even water near stored items.
- Do a manual balance test. Disconnect the opener (pull the emergency release cord) and lift the door by hand to about waist height. It should stay there on its own. If it slams down or shoots up, the spring tension is off — note it, but don't try to adjust it yourself.
- Listen to the opener during a normal cycle. Grinding, humming without movement, or a noticeable delay before the door responds are all early warning signs worth writing down.
Where DIY Ends and a Technician Should Take Over
Everything above is safe for a homeowner to handle with basic tools and twenty minutes. What's not a DIY job is anything involving the torsion or extension springs themselves. These springs are under enough tension to cause serious injury if they release suddenly, and adjusting or replacing them requires specialized bars and training. The same goes for:
- Bent or misaligned tracks that need realignment
- Frayed or damaged lift cables
- An opener motor that's grinding, overheating, or not responding to the safety reverse test
- A door that's badly out of balance (fails the manual lift test)
If your balance test, cable check, or safety reverse test turns up a problem, that's the line where it's time to call in a technician rather than keep adjusting things yourself.
When to Call Pomona Door & Opener
If your fall check turns up worn rollers, a door that won't hold its position, or an opener that sounds like it's working harder than it should, that's exactly the kind of thing our Garage Door Maintenance visits are built for — we'll inspect the full system, re-torque hardware, check cable and spring tension, and catch small issues before winter rain makes them worse.
