Windows in your flat are subject to constant use and exposure to rain and wind. Over time, normal wear and tear can cause window components to loosen or deteriorate. Homeowners are therefore required to maintain their windows in accordance with the Building and Construction Authority (BCA) Building Control Regulations.
Failure to carry out proper maintenance may result in windows becoming unstable. In severe cases, a falling window can cause serious injury or pose a danger to the public.
How Often Should You Check Your Windows?
Homeowners are advised to:
-
Inspect their windows at least once every 6 months
-
Ensure windows open and close smoothly
-
Check for loose, worn-out, or damaged parts
If you notice any signs that your windows may be unsafe or at risk of falling, you should take immediate precautionary measures and engage a BCA-approved window contractor listed with HDB to carry out the necessary repair or replacement works.
Penalties for Poor Window Maintenance
Under BCA regulations, if a window falls due to lack of maintenance, homeowners may face:
-
A fine of up to $20,000, and/or
-
Imprisonment for up to 12 months, or
-
Both
For more information, you can refer to HDB webpage.
Engaging a licensed window contractor like Ho Ho early helps prevent safety risks, legal consequences, and costly rectification works later.

When Should You Consider Replacing Your Windows Instead?
While regular maintenance and repair can address many window issues, there are situations where replacing your existing windows may be a safer and more cost-effective solution in the long run.
You may want to consider changing to new windows if:
-
Your existing windows are very old or have undergone multiple repairs
-
Safety components such as stoppers or tracks cannot be securely installed
-
Your windows is more than 20 years
Older windows may continue to deteriorate despite repeated repairs, increasing the risk of safety issues and future non-compliance.
