What Skipping This Costs You
A standard home inspection usually gives the garage door a quick glance: does it open, does it close, is there an opener. That leaves a lot on the table. Wait until after closing to find a worn spring, a rusted track, or an opener with no working safety reversal, and you're paying for an emergency repair out of pocket instead of negotiating it into the sale. Push it further into hurricane season with a door that isn't properly braced or sealed, and you risk wind damage to the door itself and water intrusion into the garage during the afternoon downpours that are routine here. None of this is dramatic to check now. It's a slow walkthrough with a flashlight, and it can save you real money before you sign anything.
The Walkthrough Checklist
1. Look at the springs
There are usually one or two torsion springs above the door, or stretched side springs if it's an older setup. Check for visible gaps in the coils, rust flaking off, or a spring that looks stretched compared to its neighbor. A failing spring means the opener is doing more lifting than it should, which shortens the opener's life and can cause the door to drop suddenly. Garage door spring repair is routine, but it's not a job to inherit without knowing about it first.
2. Check the tracks and rollers
Run your hand along the vertical and horizontal tracks. They should be straight, tightly bolted, and free of dents. Rollers should turn smoothly, not grind or stick. In this part of Florida, humidity swelling and years of moisture exposure can warp tracks just enough to throw the door off alignment without it being obvious until the door jams mid-cycle. Off track door repair gets expensive fast if it's ignored and the door comes off the rails entirely.
3. Inspect the panels for rust and swelling
Look closely at the bottom panel and any seams, especially on wood or composite doors. Moisture and salt air (worse the closer you are to the coast) cause bubbling paint, soft spots, and rust streaks at the hinges. A single damaged panel can often be replaced instead of buying a whole new door, but only if it's caught before the damage spreads to the panels next to it.
4. Test the cables
The lift cables run along the sides, connected to the bottom brackets. They should be taut with no fraying, kinks, or visible rust. A frayed cable is a safety issue, not just a mechanical one. It can snap under tension and let a heavy door fall. If you see wear here, treat it as a must-fix before move-in, not a maintenance item for later.
5. Check the opener's age and safety sensors
Ask for the opener's install date if it's on a sticker or manual left in the garage. Openers over 10-15 years old often lack modern safety reversal sensors, which are the small eyes mounted a few inches off the floor on either side of the door. Wave a broom handle through the beam while the door is closing: it should stop and reverse immediately. If it doesn't, that's not a minor fix, that's a safety hazard for kids and pets.
6. Check weatherstripping and the bottom seal
The rubber seal along the floor and the trim around the sides keep out wind-driven rain. Cracked, flattened, or missing seals mean water finds its way into the garage during storms, especially with wind-load conditions common here in hurricane season. This is cheap to replace but easy for both buyers and standard inspections to overlook.
7. Confirm the door is rated for local wind load
Ask the seller or look for a label on the door's edge indicating wind-load rating. Older doors installed before wind-load standards became common in this region may need bracing retrofits or full replacement to hold up properly in a storm.
