Maintaining window frames in the Australian climate, which can range from hot and dry to humid and coastal, is crucial for prolonging their lifespan and ensuring their optimal performance. Here are some general maintenance tips for different types of window frames:

1. General Tips for All Frames:

  • Regular Cleaning: Dust, dirt, and grime should be removed regularly from all types of window frames to prevent build-up and ensure smooth operation.
  • Check Seals and Gaskets: Inspect seals and gaskets periodically for wear and tear, and replace them as necessary to maintain insulation and prevent drafts.
  • Inspect for Damage: Regularly check for any signs of damage, like cracks or chips, and address them promptly.

2. Aluminium Frames:

  • Corrosion Prevention: For homes in coastal areas, regularly clean aluminium frames to prevent salt build-up which can lead to corrosion.
  • Lubrication: Ensure that moving parts, such as hinges and locks, are lubricated to prevent them from getting stuck or corroded.
  • Touch-Up Paint: If the frames are painted, touch up any chips or scratches to prevent corrosion and maintain aesthetics.

3. UPVC Frames:

  • Avoid Harsh Chemicals: Use mild soapy water for cleaning UPVC frames and avoid abrasive materials and strong chemicals.
  • Check Drainage Slots: Ensure that the drainage slots are free of blockages to prevent water accumulation.
  • UV Protection: While many UPVC frames are UV-resistant, periodic checks for signs of discoloration or warping are prudent.

4. Timber Frames:

  • Regular Painting or Sealing: Timber frames should be regularly painted or sealed to protect against weathering, UV damage, and pests.
  • Pest Inspection: Regularly inspect for signs of termites or other pests and treat as necessary.
  • Humidity Control: In areas with high humidity, ensure proper ventilation to prevent the wood from swelling and warping.
  • Fire Safety: In bushfire-prone areas, it’s crucial to follow local guidelines for fire-resistant finishes and treatments.

5. Glass and Screens:

  • Cleaning: Regularly clean window glass and screens to ensure clarity and prevent dirt build-up.
  • Inspect for Cracks: Regularly inspect the glass for cracks or chips, which could compromise the window’s integrity and insulation.

6. Energy Efficiency:

  • Weather Stripping: Ensure that weather stripping is intact and replace if it shows signs of wear to maintain energy efficiency.
  • Glazing Inspection: Periodically check double or triple glazing for signs of condensation or leaks.


Proactive and regular maintenance of window frames, irrespective of the material, is key to ensuring longevity, functionality, and aesthetic appeal, especially in the diverse and often harsh Australian climate.
