Wall Crack Filling in Singapore
Minor wall crack filling starts from $80 at SG QuickFix. Hairline and shrinkage cracks in plaster or paint are opened slightly, filled with a flexible filler so they are less likely to reopen, and sanded smooth. Most cracks take one to two hours. HDB recommends sealing hairline cracks with flexible sealant or elastomeric paint.

Task guide
When this may be needed
- Hairline cracks have appeared across a wall or above a door frame.

- Paint has cracked where filler was used before.
- A crack has reopened after a previous repair.
- You are preparing walls before repainting.
What the team does
The technician checks the crack first: its width, direction and whether there are water stains, because a crack that keeps widening or shows damp needs assessment rather than filler. Cosmetic cracks are opened slightly so the filler can grip, dust is removed, and a flexible filler is applied and smoothed. Joints between different wall materials get a flexible sealant, since they move slightly. Once dry, the area is sanded and left ready to paint.

FAQs
Most are cosmetic. HDB recommends sealing them with flexible sealant or elastomeric paint. Cracks that widen, run diagonally from windows or doors, or show water stains should be checked before patching.
HDB says owners maintain the finishes inside their flat. Cracks on the building's external walls should be reported to the town council.
The wall moves slightly with temperature and settling, and rigid filler cracks again. Flexible filler and sealant reduce this.
