While minor maintenance like lubricating rollers or tightening loose brackets can be done at home, major repairs should be left to professionals. Springs are under extreme tension and can snap unexpectedly. Misaligned tracks require precise adjustments, and opener issues often involve electrical troubleshooting. Incorrect repairs can cause further damage or safety risks, making expert service the best choice for long-term reliability.

Cables wear out over time due to constant tension and movement. Fraying, rust, and improper weight distribution weaken them, making them prone to snapping. If a cable breaks, the door can become lopsided or get stuck. A damaged cable also increases strain on the opener and rollers. Regular inspections help catch signs of wear early, preventing sudden failures that could leave the door inoperable.

Loud grinding or squeaking sounds usually mean the rollers, tracks, or hinges need lubrication. Worn-out rollers create friction, while loose hardware causes rattling. A failing opener motor can also produce unusual noises. If the springs are too tight or misaligned, the extra tension can strain other parts. Addressing these issues early prevents further wear and extends the door’s lifespan.

Garage doors should be professionally inspected at least once a year. High-use doors may need more frequent maintenance to check for worn-out springs, misaligned tracks, or loose cables. Seasonal changes in temperature affect door balance and spring tension. Regular servicing includes lubrication, tightening hardware, and testing safety features, reducing the risk of sudden failures and costly repairs.
