What We See After Closing
A few weeks after a sale closes, we get the same call: the new owner is standing in the garage with a door that won't budge, or one that slammed down the first time it rained. The inspection report said the door was "operational." It was, for the thirty seconds the inspector watched it open and close. General home inspectors check that a garage door moves and that the auto-reverse works when something's underneath it. They rarely open the door panel, test the spring tension, or look closely at the hardware. For a buyer, that gap can mean a surprise repair bill right after move-in. Here's what to check yourself, ideally before you make an offer or during your final walkthrough.
The Walkthrough Checklist
1. Spring Type and Visible Wear
Look above the door for the spring. If it's one thick spring running the width of the door, that's a torsion spring; if there are two smaller springs stretching along the horizontal tracks, those are extension springs. Either way, look for gaps in the coils, flat spots, or rust streaks. A spring near the end of its life might still lift the door today and fail the week after you move in. Springs don't come with a warning light — they just go.
2. Track Alignment and Rust
Run your hand along the vertical tracks. They should be straight, tightly bolted, and free of dents. Coastal salt air corrodes exposed hardware faster than inland homes see, so check for rust at the bottom brackets and rollers, especially on homes closer to the water. Rust at the bottom usually means standing water or poor drainage at the slab, which is worth noting for the inspection report, not just the door.
3. Rollers and Bearings
Open and close the door slowly and listen. Grinding or a door that jerks at the same spot every cycle points to a worn roller or bearing. Nylon rollers are cheap to replace; steel rollers that have gone this long without lubrication often mean the whole set needs attention.
4. Opener Age and Safety Reversal
Check the opener's manufacture date on the motor unit label. Anything over 10–15 years old likely lacks modern safety features like rolling-code security and photo-eye sensors that newer units have standard. Test the reversal by placing a piece of wood on the ground where the door closes — it should stop and reverse immediately. If it doesn't, that's a liability, not a convenience issue.
5. Wall Bracing and Header Reinforcement
In this part of California, garage doors are a known weak point in a home's seismic retrofit. Look at where the track brackets anchor into the wall studs or header. Loose, stripped, or missing lag bolts here mean the door could pull free from the frame during strong shaking — a detail most inspectors never mention because it's outside a standard structural scope.
6. Bottom Seal and Weatherstripping
Check the rubber seal along the bottom of the door. Cracked, flattened, or missing seals let in wind-driven rain during winter storms and let dust and wildfire smoke in during dry months. It's a small part, but a bad seal is often the first sign of a door that's out of balance and hitting the floor harder than it should.
7. Balance Test
Disconnect the opener using the release cord, then lift the door halfway by hand. It should stay in place on its own. If it drifts up or crashes down, the springs are no longer matched to the door's weight — a problem that strains the opener motor every single time it runs.
8. Panel Dents and Previous Patch Jobs
Dents near the bottom corners usually mean a past bump from a car bumper. Cosmetic, but worth noting if it's thrown the door out of square, which shows up as uneven gaps at the sides.
