It is important to check and repair windows regularly to ensure they remain safe and secure. If a window falls due to lack of maintenance, owners can face a fine of up to $10,000 and/or jail term of up to one year or both.
Tip: Check your windows every year on 6 June (6/6) and 12 December (12/12).

- Using a mirror, check that fasteners are not rusty or loose. Screws and rivets are located at the top and underside of the window panel.
- Clean and oil joints or moving parts.
- Change all rivets from aluminium to stainless steel by engaging an approved window contractor.
