Aluminum windows and doors are popular for their strength, sleek appearance, and low maintenance requirements. Unlike wood, aluminum does not warp or rot, making it a long-lasting choice for modern homes. However, proper care can significantly extend their lifespan and keep them performing like new. Here’s a practical guide on how to maintain your aluminum windows and doors.
1. Regular Cleaning
Dust, dirt, and pollution can accumulate on frames and glass over time. To keep them looking fresh:
- Use a soft cloth or sponge with mild soap and water.
- Avoid abrasive cleaners or steel wool, which can damage the finish.
- Rinse thoroughly with clean water to prevent residue buildup.
For best results, clean your aluminum windows and doors at least twice a year, or more often if you live in coastal or industrial areas.
2. Lubricate Moving Parts
Smooth operation depends on well-maintained hardware.
- Apply a silicone-based lubricant to hinges, locks, and sliding tracks every 6–12 months.
- Avoid oil-based lubricants that attract dust and grime.
- Check for signs of wear and replace damaged hardware promptly.
3. Inspect Weatherstripping and Seals
Weatherstripping plays a vital role in energy efficiency and insulation.
- Look for cracks, gaps, or wear in the seals around your windows and doors.
- Replace damaged weatherstripping to maintain airtight performance.
- Ensure drainage holes are clear to prevent water buildup.
4. Prevent Corrosion in Coastal Areas
If you live near the ocean, salt deposits can accelerate corrosion.
- Rinse aluminum frames with fresh water regularly.
- Apply protective coatings (like wax or a clear sealant) to shield against salt exposure.
5. Check Glass and Frames
- Inspect for chips, cracks, or scratches in the glass and frames.
- Small damages should be repaired immediately to prevent further issues.
- Ensure frames are tightly secured and aligned to avoid air or water leaks.
6. Maintain Paint or Powder Coating
The finish protects aluminum from corrosion and adds aesthetic value.
- Wash coated surfaces gently to retain their shine.
- Touch up any scratches or chips to prevent exposure to moisture.
