Most home inspectors test whether the garage door opens, closes, and reverses when it hits something. That's it. They rarely pull a panel apart, check spring wind, or look closely at how the door has held up against Florida humidity and storm wind. If you're buying a house with an attached garage, here's what to check yourself before you sign, and what it means if something fails.
Walk the Garage with This List
- Count the spring coils and look for rust pitting. A torsion spring with visible rust, gaps between coils, or a coil that looks stretched compared to the others is near the end of its life. Springs are rated for a number of open/close cycles, and once they're close to that limit they can snap without warning. A failed spring means the door won't lift at all, or will slam down hard enough to damage the opener or hurt someone standing underneath.
- Check the lift cables at the bottom bracket. Look for frayed strands, kinks, or rust where the cable wraps around the drum. A fraying cable is a sign the door is close to becoming unbalanced on one side, which puts extra strain on the opener and can cause the door to hang crooked in the track.
- Run your hand along the tracks. They should be straight, tightly bolted to the frame, and free of dents or rust streaks. Bent or loose tracks usually mean the door has come off track before, even if someone bent it back into rough shape. That's a repeat problem waiting to happen, especially after a hard wind gust pushes against the door.
- Look at the rollers. Plain plastic rollers wear out faster and squeal more in humid air than nylon ones. Cracked, flat-spotted, or missing rollers mean the door isn't rolling smoothly, which adds wear to the tracks and the opener motor.
- Check the bottom 12 inches of the door panels. This is where rust and swelling show up first from ground moisture and afternoon downpours. On steel doors, look for bubbling paint or soft spots. On wood or composite doors, press on the bottom panel — if it gives or feels spongy, water has gotten into the core.
- Test the auto-reverse safety feature. Place a 2x4 flat on the ground where the door closes. It should reverse immediately on contact. If it doesn't, the force settings are off or the sensors are failing — both are safety issues, not just inconvenience.
- Check the photo-eye sensors near the floor on each side of the track. They should be aligned and free of corrosion. Misaligned sensors are a common cause of a door that won't close, and salt air or moisture buildup can corrode the contacts over time.
- Ask about the door's wind-load rating. Homes in this area need doors and bracing built to handle storm-force wind, and not every door — especially an older, unreinforced one — meets that standard. If the listing doesn't mention it and the door looks original to an older house, assume it hasn't been upgraded.
- Disconnect the opener and lift the door by hand. It should move smoothly and stay roughly where you leave it, about halfway up. If it feels heavy, drops on its own, or you have to fight it, the springs are out of balance — even if the opener makes it look fine when it's doing the lifting.
Why Inspectors Miss This
Standard home inspections are built around a quick functional test, not a mechanical teardown. Spring tension, cable wear, and wind-bracing aren't things most inspectors are trained or equipped to evaluate in the few minutes they spend in the garage.
