Aluminium Bi-fold Door Maintenance: How to Keep Them Working Perfectly

Aluminium bi-fold doors require very little maintenance compared with timber alternatives — but the small amount they do need makes a significant difference to their lifespan and operation. Here is the annual maintenance routine that keeps them working perfectly.

What This Guide Covers

• Clean tracks and rollers every 6 months — debris is the primary cause of operation problems
• Lubricate rollers, hinges, and locking mechanisms with silicone spray — never oil-based products
• Check and tighten all visible screws and bolts annually — vibration loosens them over time
• Inspect and replace weather seals every 5–7 years — this restores draught and weather performance
• Adjust threshold seals seasonally — frames can move slightly with temperature changes
