There were 16 cases of fallen windows in the first five months of this year and most could have been prevented with regular maintenance.
This is one fewer than in the same period last year, and well below the 27 cases in the same period of 2014.
Homeowners should maintain their windows every six months, said the Building and Construction Authority (BCA) in a statement yesterday.
Out of the 16 fallen windows, 11 were casement types. Most of these were found to have corroded aluminium rivets which came loose from the window stays.
Most of the sliding windows that fell did not have safety stoppers and angle strips to secure the window panels, and the windows could not slide smoothly along the tracks.
Homeowners are required to engage an approved window contractor to retrofit the aluminium rivets of casement windows with stainless steel rivets or screws.
If a window falls due to lack of maintenance, homeowners can be fined up to $10,000 and/or jailed for up to one year.
Those who fail to replace aluminium rivets in casement windows with stainless steel rivets can face a a fine of up to $5,000 and/or jail of up to six months. Since 2006, 303 people have been fined.
"Everyone should play his part in checking and maintaining his windows regularly to create a safe and liveable environment for fellow Singaporeans," said Mr Lim Beng Kwee, director of BCA special functions group. "Falling windows pose a safety risk to the public, given our highly built-up environment."
