Aircraft Hangar Door Maintenance Services
Maintaining the safety and functionality of aircraft hangar doors is a crucial part of protecting your aviation investment. Whether housing a single private aircraft or an entire fleet, hangars must remain secure and operational. Cirrus Construction, Inc. provides detailed hangar door inspection and maintenance services across the Triad region of North Carolina, including Greensboro, High Point, and Winston-Salem.
Why Hangar Door Maintenance Matters
The hangar door is often the most complex and expensive component of the entire structure. It must operate smoothly and reliably—often in demanding conditions. Regular maintenance prevents costly breakdowns, reduces safety risks, and extends the life of the hangar itself.
No matter the configuration—T-hangars, box hangars, or custom aircraft storage—the performance of the door system is essential. Failure to maintain components like cables, rollers, hinges, and electrical switches can lead to door failure, aircraft exposure, or even personal injury.
Bi-Fold and Sliding Door Maintenance Checklist
For hangars equipped with bi-fold, sliding, stacking, or rolling doors, the following maintenance actions are recommended:
- Inspect and lubricate hinges, cable sheaves, and chains every 3–6 months.
- Check unlocking cables for proper function; replace any that are damaged or frayed.
- Replace lifting cables if they show signs of kinks, corrosion, or fraying.
- Inspect tension springs and replace if damaged or weakened.
- Check chain-and-sprocket systems for wear or corrosion.
- Test the operating switch to ensure it returns to neutral when released.
- Verify that all motor mount bolts and hardware are tight and secure.
- Inspect hinge pin cotter pins for signs of fatigue or misalignment.
- Test drive belt tension and realign as needed.
- Grease door rollers, cable drum bearings, and threaded limit switch rods.
- Clear any debris, insects, or spiderwebs from tracks and electrical boxes.
- Check upper and lower door stop checks and overrun switches.
Signs of Potential Failure
Routine inspections can catch small issues before they become major problems. Be aware of the following warning signs:
- Unusual grinding or squealing during door operation
- Jerky or uneven lifting motion
- Delayed switch response
- Visible rust or corrosion on cables or motor mounts
- Misaligned tracks or sagging doors
- Electrical malfunctions or unresponsive control switches

Need Help With Hangar Door Maintenance?
If you're unsure whether your hangar door system is performing as it should, a scheduled inspection can help identify any issues early. Preventive maintenance reduces long-term repair costs and helps ensure operational safety. For clients who don't have the time or expertise to perform regular maintenance, an experienced contractor can assist with routine inspections and any necessary adjustments or repairs.
While some tasks can be completed in-house, it's recommended to consult a qualified service provider for motor adjustments, safety switch calibration, and cable replacement. Professional maintenance improves reliability and supports compliance with airport and aviation safety standards.
