Aluminium windows are known for their durability and low maintenance, but like any building component, they can develop problems over time. Many common issues are related to hardware, dirt, incorrect adjustment, poor sealing, or improper installation. Identifying the cause early can help prevent bigger repairs.
1. Sliding Window Is Difficult to Move
One of the most common problems with sliding windows is increased resistance while opening or closing.
Dirt, dust, damaged rollers, or track damage may be responsible. Start by cleaning the track thoroughly. If the problem continues, the rollers may need adjustment or replacement.
Avoid forcing the shutter because excessive pressure can damage the hardware or frame.
2. Water Leakage
Water entering around an aluminium window can occur because of damaged sealant, blocked drainage holes, poor installation, or gaps around the frame.
Check the external sealant and drainage paths. Weep holes should remain clear so that accumulated water can drain outside.
If leakage continues, professional inspection may be necessary.
3. Loose Handles or Locks
Handles and locks can become loose through regular use. In some cases, tightening the appropriate screws can solve the problem.
However, damaged or worn hardware may require replacement rather than repeated tightening.
4. Air Gaps and Drafts
Air movement around the frame may indicate damaged gaskets, poor sealing, or gaps between the frame and wall.
The sealing system should be inspected, and damaged components should be replaced where necessary.
5. Window Does Not Close Properly
A window may fail to close properly because the frame has shifted, hinges are misaligned, rollers are damaged, or the shutter has become difficult to operate.
Don’t force the shutter. The hardware and frame alignment should be inspected to identify the actual cause.
6. Condensation on Glass
Condensation occurs when moisture in the air comes into contact with a colder glass surface. It may be more noticeable in bathrooms, kitchens, or poorly ventilated rooms.
Improving ventilation and reducing indoor humidity can help. If condensation occurs between sealed glass panes, the insulating glass unit may require professional evaluation.
7. Noisy Window Operation
Squeaking or rattling can be caused by loose hardware, worn rollers, dirt, or movement in the frame.
Cleaning and adjusting the hardware may resolve minor problems. Persistent noise should be inspected by a window professional.
8. Damaged Sealant
Sealant can deteriorate due to age, weather exposure, or poor application. Cracked or separated sealant should not simply be ignored because it can contribute to water and air leakage.
The damaged sealant may need to be removed and replaced using an appropriate product.
How to Prevent Aluminium Window Problems
Regular cleaning is one of the easiest ways to maintain aluminium windows. Keep tracks and drainage holes clear, operate shutters gently, and inspect seals and hardware periodically.
Avoid using harsh cleaning chemicals that may damage the surface finish.
Conclusion
Most aluminium window problems can be prevented or corrected when they are identified early. Regular maintenance, proper cleaning, timely hardware replacement, and professional repairs can help keep aluminium windows operating smoothly for many years.
