Maintenance Month: The Garage Door Service Checklist You Shouldn’t Ignore
Your garage door works harder than you think. Lifting, lowering, locking and also protecting your car and home from the elements every single day. Yet, most homeowners don’t give it a second thought until something creaks, sticks or refuses to budge.Just like your car needs its service, your garage door also requires regular maintenance to keep it running smoothly and safely. Be it the salty air of Blouberg or the wind of Durbanville, a little attention now will save you later. Here is your simple checklist for keeping your garage door in top shape, straight from the experts at Planet Automation Cape Town.
1. Check the Rollers and Tracks
The rollers and tracks take most of the movement of your door, guiding it up and down every time you press that button. Dust, sand and rust, especially from Cape Town’s coastal air, can cause damage and wear.
What to do:
• Inspect for dirt, dents or any rust buildup.
• Clean it with a dry cloth and apply a non-silicone based lubricant.
• Replace worn or chipped rollers.
Pro tip: Avoid any grease as it attracts grime that can jam the track over time.
2. Test the Balance and Spring Tension
A correctly balanced garage door would remain in place when opened halfway. If it slams shut or moves up, your springs are likely under too much strain.
Why it matters: Poor balance puts pressure on your motor, causing it to burn out sooner, especially during Cape Town’s temperature swings, which affect metal tension.
What to do:
• Disconnect the motor.
• Open the door halfway.
• If it isn’t remaining in place, then call a technician to safely adjust the springs.
Stat: According to Centurion Systems’ 2024 maintenance data, poorly balanced doors increase motor strain by up to 30%.
3. Check the Sensors and Safety Beams
Modern garage doors rely on infrared safety sensors to avoid accidents. If these beams are misaligned or dirty, your door won’t close properly, or even worse, won’t reverse in an emergency.
What to do:
• Wipe the sensor lenses with a soft cloth.
• Make sure they’re aligned at the same height.
• Test by blocking the beam while closing. The door should immediately reverse.
Pro tip: if your sensors flicker during load shedding recovery, check for power surge damage or loose wiring.
4. Lubricate Moving Parts
Friction is an enemy of your door. Regular lubrication keeps everything running smoothly and quietly.
What to do:
• Apply silicone spray or lithium grease to hinges, springs and the pulleys.
• Wipe off the excess to avoid drips or dust buildup.
• Repeat every 2–3 months, especially in coastal or humid conditions.
5. Check Remote Controls and Backup Batteries
We have seen it time and time again. The “broken” garage door that just needs fresh batteries.
What to do:
• Replace your remotes batteries every 6–12 months.
• Check the back-up batteries in your motor, especially if you have been experiencing frequent load shedding.
• Keep an extra remote programmed and ready. You will thank yourself later.
Pro Tip: If your door opens slower after a power outage, it often means the backup battery is signaling for replacement.
6. Inspect Weather Seals and Panels
Cape Town’s coastal climate seems to chew through rubber seals and corrode metal panels over time.
What to do:
• Check seals for cracks, gaps, or peeling.
• Replace worn bottom seals to keep out moisture and dust.
• Rinse the door panels every quarter if you live near the sea to get rid of salt residue.
The simplicity of a maintenance routine makes all the difference between a smoothly running system and an expensive repair bill. Regular checks will keep your door reliable, extend its life, and ensure that it operates with safety each time you hit “open.”
