Find the Cause of Window Air Leakage Before Replacing the Window
Air leakage around an aluminium or uPVC window can come from worn rubber beading, gaps, poor closing, alignment or related window conditions. Kutbi checks the existing system before recommending suitable sealing or repair.
Worn rubber beading
Old, hardened or damaged beading can reduce the seal around an existing window.
Rubber Beading Replacement →Window gaps
Visible gaps around the shutter or frame can allow unwanted air movement and may need suitable gap sealing.
Window Gap Sealing →Alignment or closing problem
A shutter that does not sit or close correctly can leave inconsistent contact around the opening.
Alignment Repair →Sliding-system problem
On sliding windows, wheels, rollers and tracks can affect shutter position and closing.

- Identify where air is entering and when the problem occurs.
- Inspect visible beading, seals, gaps and shutter position.
- Check alignment and relevant track, wheel or roller components where applicable.
- Identify the likely source instead of assuming complete window replacement is required.

Window Air Leakage Repair FAQs
Why is air coming through my closed window?
Possible causes include worn seals or beading, gaps, alignment issues, incomplete closing and sliding-system problems.
Can rubber beading stop window air leakage?
If deteriorated beading is the cause, suitable beading replacement can restore the seal around the window.
Can a sliding window be repaired if it lets air in?
Suitable existing sliding windows can be assessed for alignment, rollers, tracks, seals and closing problems.
Should I seal the gap without checking the window?
Not always. If alignment, closing or component wear is causing the gap, sealing alone may not solve the underlying problem.
Can aluminium windows have air leakage?
Yes. Air leakage can occur when sealing, gaps, alignment or closing conditions are not working correctly.
Can I send a photo first?
Yes. A clear photo of the complete window and the area where air enters can help with an initial assessment.
