You're standing in the garage during the final walkthrough, keys to a new house almost in hand. You press the wall button out of habit, and the door shudders instead of gliding. Or maybe it's quieter than that — you just notice a rust streak running down the track, or a bottom panel that looks slightly bowed where the Florida humidity has been working on it for years. The home inspector checked the box that says "garage door opens and closes." That's often as far as it goes.
A general inspection usually isn't built to catch the slower problems — the ones caused by years of heat, moisture, and storm cycles specific to this part of Florida. Here's what to check yourself before you close, and what it means if something fails.
The Walkthrough Checklist
1. Lift test with the opener disconnected
Pull the manual release cord so the door is no longer connected to the opener. Lift the door by hand to about waist height and let go. It should stay put. If it drops or shoots up, the springs are out of balance — a sign of wear that usually means spring replacement before the door starts stressing the opener and cables.
2. Spring coils up close
Look at the torsion spring (usually a thick coil above the door) or extension springs (along the upper tracks). Check for rust pitting, visible gaps between coils, or a spring that looks stretched compared to its neighbor. Humidity speeds up corrosion here, and a rusted spring is a safety risk, not just a cosmetic one.
3. Cables and rollers
Look at the cables running alongside the springs for fraying strands, and check rollers for cracks or flat spots. Nylon rollers crack with age and heat; steel rollers rust. Either one failing mid-cycle can cause the door to jump track.
4. Track alignment and rust at the base
Rust tends to collect at the bottom few feet of track, especially if the garage has ever taken on water during heavy afternoon storms. Sight down the track from the floor — gaps, bends, or flaking rust mean the door may be working harder than it should, straining the opener.
5. Bottom seal and weatherstripping
Press on the rubber seal along the bottom of the door. If it's brittle, torn, or compressed flat, water and humidity have likely been getting into the garage during storm season — which can mean hidden moisture damage to anything stored near the door, and a path for pests.
6. Panel condition — rust bubbles and swelling
Run a hand over steel panels looking for small bubbles under the paint (early rust) and check wood or composite doors for swelling or soft spots near the bottom corners. Moisture exposure here is a long-term cost — once a panel starts to go, repainting won't fix it.
7. Wind-load bracing
Open the door and look at the horizontal bracing on the back of the panels. Homes built or re-roofed with storm readiness in mind often have reinforced doors meant to handle wind-load requirements. A door without visible bracing on an older home may need upgrading before the next hurricane season rolls through.
8. Opener age and auto-reverse safety
Place a 2x4 flat on the ground where the door would close. The door should reverse the moment it touches the wood. If it doesn't, the safety sensors or force settings need attention immediately — this is a basic safety feature, not an optional one.
9. Noise during a full open-close cycle
Run the door through a complete cycle and listen. Grinding usually means roller or bearing wear; a loud bang partway through can mean a spring is close to failing. Either one is worth flagging before you own the problem.
