Key Takeaways

HDB advises checking your flat windows every six months for loose, worn or damaged parts.
Repairs, retrofitting and replacement of HDB windows must use a BCA-approved window contractor listed with HDB.
If a window falls because of poor maintenance, the penalties can include a fine up to S$20,000 and/or imprisonment up to 12 months.

Why check HDB windows every six months?

HDB advises homeowners to inspect their windows once every six months. Windows are exposed to repeated opening, closing, rain and wind, so hinges, fasteners and other parts can loosen or wear over time.

What should you look for?

loose or missing screws, rivets or fasteners
hinges that feel stiff, loose or corroded
handles and latches that no longer close securely
panels that scrape, wobble or do not move smoothly
cracks or damage around the frame
signs that a window panel could detach or fall

If a window appears unsafe, secure the area and arrange professional repair instead of continuing to use it.

Who can repair or replace HDB windows?

HDB states that window repair, replacement and retrofitting work must be carried out by a BCA-approved window contractor listed with HDB.

This is different from ordinary minor home repairs, where homeowners may have more contractor choice.

Permit and completion-report process

For regulated window work, your contractor handles the relevant permit application to HDB. HDB also states that the appointed contractor must submit the relevant window report(s) to BCA within 14 days after completion.

Keep a copy of the report for your records.

What are the penalties for unsafe windows?

HDB warns that if a window falls because of poor maintenance, homeowners can face a fine of up to S$20,000, imprisonment of up to 12 months, or both.

There are also separate penalties for non-compliance with certain window-retrofitting requirements.

Casement vs sliding windows

Different window types have different wear points. Casement windows rely heavily on hinges, stays and rivets; sliding windows need smooth tracks, secure panels and working locks. Follow HDB's specific maintenance guidance for your window type.

Can full-height windows simply be replaced?

HDB's renovation guidelines state that replacement of full-height windows is generally not allowed, except where permission is granted for situations such as a damaged frame requiring complete replacement.

If the window work forms part of a larger project, also read our HDB Renovation Rules. For air-conditioning works near windows or ledges, see our HDB Air-Con Installation Rules.
