A general home inspector usually gives the garage door a few minutes: open it, close it, note if it moves. They rarely test the spring balance, check for storm-related wind damage, or catch the early rust that Alabama humidity causes inside the track. Skip these checks before you close, and you could be facing a snapped spring during the first big afternoon storm of next hurricane season, or a $700–$2,500 full replacement bill instead of a $150–$350 spring swap. Walk the garage with this list before you sign anything.
The Checklist
1. Spring Balance Test
Disconnect the opener (pull the red release cord), then lift the door halfway by hand. It should stay put on its own. If it slides down or shoots up, the springs are worn or mismatched for the door's weight. If it fails: expect a spring replacement soon, and in the meantime the opener is working overtime, which shortens its life too.
2. Rust on Springs, Hinges, and Track Bolts
Look closely at the torsion spring coils and the hinges connecting panels. Humidity and afternoon downpours drive moisture into garages that don't seal well, and surface rust on a spring is an early warning it's weakening from the inside. If it fails: budget for spring or hardware replacement within the year, not a deep-future problem.
3. Panel Swelling or Warping
Run a hand along the bottom two panels, where moisture collects. Wood-composite doors swell and delaminate; steel doors can rust from the inside out where insulation holds dampness. If it fails: you're looking at panel replacement, or a full door if more than one or two panels are affected.
4. Bottom Weatherseal Condition
Check the rubber strip along the floor. Cracked, flattened, or missing seal lets water in during heavy rain and invites pests and humidity into the garage. If it fails: it's a cheap fix now, but ignored seals lead to the panel swelling problem above.
5. Track Alignment and Gaps
Stand back and sight down both tracks. Gaps between rollers and track, or tracks that lean inward or outward, often mean the slab has settled slightly or the tracks were never anchored properly. If it fails: the door can bind, jump track, or wear the opener motor out faster.
6. Wind-Load Bracing
Look at the back of the door for horizontal struts bolted across the panels. Coastal Alabama and storm-exposed inland areas both see doors rated for wind resistance, and a door without reinforcement can buckle or blow in during hurricane-season gusts. If it fails: ask whether the door meets wind-load standards for the area before you rely on the garage as a safe room or storage for anything valuable.
7. Auto-Reverse Safety Sensors
Wave a broom handle under the door while it's closing. It should reverse immediately. Older openers may not have working sensors at all. If it fails: this is a safety issue first, and often means the opener itself is past its useful life.
8. Cables and Pulleys
Look at the thin cables running alongside the tracks down to the bottom brackets. Frayed strands or visible rust mean they're near failure. If it fails: a snapped cable can let one side of the door drop suddenly, which is dangerous and often damages the track too.
9. Opener Age and Battery Backup
Check the manufacture date on the opener's label if you can find it. Openers over 10-15 years old lack rolling-code security and battery backup, which matters when storms knock out power and you need the door to open manually or on battery. If it fails: plan on an opener upgrade, especially if you're relying on the garage door for access during outages.
