Aluminium windows and doors are a favourite across South Africa—and for good reason. They’re strong, modern-looking, and don’t ask for much in the way of maintenance. But just like anything else in your home, they can start to show signs of wear over time, especially if they haven’t been installed properly or maintained regularly.
So, what should you be on the lookout for? Let’s go through some of the most common issues and how to deal with them before they turn into bigger headaches.
1. Sticking or Jamming
Ever tried to open a window or sliding door and it just won’t budge? You’re not alone. This is one of the most common complaints.
Why it happens:
- Dirt and debris build up in the tracks
- Frames shift due to settling or poor installation
- Rollers on sliding doors wear out
Quick fix: Clean out the tracks and give the moving parts a bit of lubricant. If the problem keeps coming back, you might need to adjust or replace the hardware.
2. Water Leaks
Noticing damp spots around your windows or doors after a rainstorm? That’s a red flag.
Common causes:
- Worn-out weather seals
- Poor installation
- Blocked drainage holes
Tip: Check seals and clear any clogs in the drainage system. Proper water flow can save you from costly water damage later.
3. Condensation Between Panes
Double-glazed aluminium windows are great for energy efficiency—until the seal fails.
What to look for:
- Fog or moisture trapped between the glass layers
- A decline in insulation performance
Unfortunately, this isn’t something a quick wipe will fix. The best solution is to replace the glass unit to restore proper insulation.
4. Corrosion or Oxidation
Aluminium doesn’t rust, but it can still corrode—especially near the coast.
Signs include:
- A white, chalky film
- Pitting on the surface
To extend the life of your windows, give them a regular clean and consider anti-corrosion treatments, especially if you’re in a salty-air zone.
5. Loose or Broken Handles & Locks
Handles and locks take a beating from daily use. Over time, they can loosen or break altogether.
Why it matters:
It’s not just annoying—it’s also a security concern.
Solution: Tighten or replace hardware as soon as you notice something’s off. Don’t wait for it to completely fail.
6. Broken or Worn Hinges
Hinges are small but mighty. When they go, they take smooth operation with them.
Common symptoms:
- Windows or doors start to sag
- Difficulty opening or closing properly
Replacing worn hinges can restore function and prevent further damage.
7. Drafts or Poor Insulation
Feeling a chilly breeze even with the windows shut? That’s a sign of poor insulation.
What to check:
- Rubber seals that have dried out or cracked
- Gaps in the frame
Fixing this not only improves comfort but can also cut down on your energy bill.
8. Scratches or Dents
Aluminium may be tough, but it’s not invincible. Scratches and dents happen—especially during installation or renovations.
Is it serious?
Most surface damage is cosmetic, but deep dents can impact functionality. Protective films and gentle handling go a long way.
Simple Maintenance Tips
Keep your aluminium doors and windows in good shape with a few easy habits:
- Wipe down tracks and frames regularly
- Check seals, handles, and hinges twice a year
- Use silicone spray on moving parts
- Touch up or repaint damaged areas to prevent corrosion
Final Thoughts
Aluminium windows and doors are a great addition to any home—stylish, practical, and built to last. But like anything else, a little care goes a long way. By knowing what to look for and staying on top of maintenance, you can keep them working smoothly for years to come.
And if you ever feel out of your depth, don’t hesitate to call in a professional who knows aluminium systems inside and out.
