Most garage door problems don’t happen suddenly. They build up slowly — a little rust here, a worn roller there, a spring that’s been under stress for years. By the time the door stops working, the damage is already done.
A simple annual check takes about 15 minutes and can add years to the life of your system. Here’s exactly what to look for as a South Carolina homeowner.
Visual Inspection — Start Here
Before touching anything, stand back and look at the full door. Then open and close it once and watch carefully.
Does the door move smoothly?
It should open and close in one fluid motion without jerking, shaking, or pausing. Any hesitation usually means a roller, hinge, or track issue.
Does it close evenly?
Both sides of the door should touch the ground at the same time. If one side hits first, the spring tension is uneven — this needs a professional adjustment.
Any rust, cracks, or warping?
In SC’s humidity, surface rust on steel doors is common. Catch it early with rust-inhibiting paint and it’s a minor fix. Leave it and it spreads under the panels and becomes structural.
The Balance Test
This is the most important test you can do and almost no one does it. It tells you whether your springs are properly tensioned.
How to do it
Disconnect the opener by pulling the red emergency cord. Manually lift the door to about waist height and let go. A properly balanced door should stay in place — or drop very slightly. If it falls quickly or shoots up, the springs are out of balance.
Why it matters
An unbalanced door forces the opener motor to work harder than it was designed to. This shortens the life of the opener significantly — and it’s a sign the springs are nearing the end of their life.
Lubrication — What to Lubricate and What Not To
SC’s heat and humidity accelerates wear on moving parts. Proper lubrication once a year makes a significant difference.
What to lubricate
Springs, hinges, rollers, and the top of the rail where the chain or belt runs. Use a garage door specific lubricant or white lithium grease — not WD-40, which evaporates quickly and attracts dirt.
What not to lubricate
The tracks. People think lubricating the tracks helps — it doesn’t. Greasy tracks cause rollers to slip, which makes the door operate less smoothly and can cause it to jump off track.
Check the Weatherstripping
The rubber seal along the bottom and sides of the door is your first line of defense against SC’s humidity, insects, and heat. It degrades faster here than in cooler climates.
Check for cracks, gaps, or sections that have pulled away from the door. Replacement weatherstripping is inexpensive and easy to install — and a failing seal means moisture, bugs, and heat are getting into your garage year-round.
Your Annual Checklist
Visual inspection — smooth movement, even closing, no rust or warping
Balance test — door holds at waist height when released
Lubricate springs, hinges, rollers — not the tracks
Check weatherstripping for cracks and gaps
Check safety sensors — both lights solid, no obstructions
Test auto-reverse — place a 2×4 flat on the ground and close the door. It should reverse on contact
