Window Replacement and Safety Guide

Mandatory Compliance and Cost Breakdown

Neglecting window maintenance or hiring an unapproved contractor for replacement is not just risky—it's illegal. Fallen windows due to poor maintenance or faulty installation can lead to a fine of up to S$10,000 and/or jail time.

Your responsibility as the homeowner is to ensure all replacement works are performed by a contractor who meets the following strict criteria:

HDB Window Replacement Cost Breakdown (2025 Estimates)

The cost of replacing windows in an HDB flat is typically quoted either per panel or as an all-inclusive package deal based on the flat type. Prices vary significantly based on window type and material thickness.

*Note: Prices generally include standard aluminium frames, clear glass, dismantling, disposal of old units, and HDB permit submission. Premium materials (like uPVC) or soundproof double-glazing will significantly increase the cost.

Casement vs. Sliding Windows—Which is Best for Your HDB?

Choosing the right type of window impacts ventilation, noise control, and maintenance.
Both casement and sliding windows are HDB-approved, but they serve different purposes:

The Mandatory 6-Month Window Safety Check

The Building and Construction Authority (BCA) requires all homeowners to conduct simple checks every six months. Failure to maintain the windows, leading to detachment, carries severe penalties.

If you have casement (swing-out) windows, you must specifically check the rivets holding the friction stays (the supporting metal arms) to the window frame.

Your 5-Point Safety Checklist (Required by Law)

1. Check the Rivets: Look closely at the rivets and screws securing the friction stays (support arms) to the window frame. If any are loose, corroded, or missing, call for immediate professional attention
   

2. .Test the Movement: Open and close the windows gently. If there is stiffness, squeaking, or difficulty, the hinges/tracks may need professional lubrication or replacement.
   

3. Check the Sealing: For casement windows, ensure the seal (gasket) around the window frame is still pliable and not cracked, which affects soundproofing and rain resistance.
   

4. Inspect the Locks: Ensure the handles and locking mechanisms are secure and can lock the window tightly against the frame.
   

5. Clean the Tracks (Sliding): Use a stiff brush and a vacuum to remove all dust, grit, and debris from the sliding tracks. This is the simplest way to prolong their lifespan.
