⚠️ Common Problems with Aluminium Sliding Windows and How to Fix Them
Aluminium sliding windows are durable and stylish, but like any window system, they can face common issues over time. Knowing how to identify and fix these problems can save you money and extend your windows’ lifespan.
Here’s a rundown of frequent problems and practical solutions for aluminium sliding windows.
1️⃣ Window Sticking or Jamming
Cause: Dirt, dust, or debris buildup in the tracks; damaged rollers; misalignment.
Fix:
Clean tracks thoroughly by vacuuming and wiping with a damp cloth.
Lubricate rollers and tracks with a silicone-based lubricant.
If rollers are damaged, replace them (often a simple DIY fix).
Check for frame warping or misalignment and adjust if necessary.
2️⃣ Difficulty Sliding or Opening
Cause: Worn-out or broken rollers; track damage; warped frame.
Fix:
Inspect and replace faulty rollers.
Clean and smoothen tracks to remove obstructions.
If the frame is warped, professional realignment or replacement may be needed.
3️⃣ Condensation Between Glass Panes
Cause: Broken seal in double-glazed units allowing moisture ingress.
Fix:
Unfortunately, sealed unit replacement is the only permanent solution.
Temporary fix: Use a dehumidifier indoors and ensure proper ventilation.
4️⃣ Corrosion or Oxidation on Frame
Cause: Exposure to moisture and salty air (common near coastal areas); scratches exposing bare metal.
Fix:
Clean corroded areas and apply aluminium-safe corrosion inhibitors.
Touch up with powder coating or paint designed for aluminium.
Consider regular maintenance to prevent recurrence.
5️⃣ Damaged or Broken Locks
Cause: Wear and tear; attempted forced entry; misalignment.
Fix:
Lubricate locks regularly.
Replace broken or faulty locking mechanisms.
Upgrade to multi-point locking systems for improved security.
6️⃣ Air or Water Leakage
Cause: Damaged seals, weather stripping, or improper installation.
Fix:
Inspect and replace worn or cracked seals and weather stripping.
Re-seal edges with appropriate silicone sealant.
Consult professionals if leakage persists due to installation issues.
???? Final Thoughts
Most common aluminium sliding window problems can be prevented or resolved with regular maintenance and timely repairs. Early attention helps maintain smooth operation, security, and energy efficiency.
