Aluminium windows are durable and low-maintenance, but they can develop problems over time. This guide will help you identify common issues and decide whether to fix them yourself or call a professional.

Common Aluminium Window Problems

1. Stuck or Hard to Open Windows

Causes: Dirt buildup in tracks, warped frames, or damaged rollers.

DIY Fix: Clean the tracks with a brush and apply silicone lubricant. If rollers are worn, they need replacement.

Call a Professional If: The frame is bent or the window still doesn't move smoothly after cleaning.

2. Water Leakage During Rain

Causes: Damaged rubber seals, gaps between frame and wall, or clogged drainage holes.

DIY Fix: Clear drainage holes and apply silicone sealant to small gaps.

Call a Professional If: Seals need full replacement or the frame has shifted.

3. Broken Handles or Locks

Causes: Wear and tear, forcing stuck windows, or poor quality hardware.

DIY Fix: Simple handle replacements can be done with a screwdriver if you have matching parts.

Call a Professional If: The lock mechanism is internal or you can't find matching hardware.

4. Squeaking or Grinding Noise

Causes: Lack of lubrication, misaligned tracks, or damaged rollers.

DIY Fix: Apply silicone spray to tracks and moving parts. Avoid oil-based lubricants as they attract dust.

Call a Professional If: Noise continues after lubrication.

When to Call a Professional

While some repairs are simple DIY tasks, certain problems require professional expertise:

  • Cracked or broken glass replacement
  • Bent or warped aluminium frames
  • Complete seal replacement
  • Window not closing properly despite cleaning
  • Multiple windows having the same problem
  • Windows older than 15 years needing restoration
