Wall and floor hacking in a Singapore HDB typically costs between $1,500 to $4,000 depending on the scale of demolition, haulage, and debris clearance required. All hacking works strictly require an HDB hacking permit, and hiring a direct contractor ensures safe, structural compliance without expensive middleman interior design markups.
Why Hacking Requires a Direct, Licensed Contractor
Hacking is the most critical and heavily regulated phase of any renovation. It involves demolishing existing floor tiles, knocking down partition walls to create open-concept spaces, or removing old built-in carpentry.
Because of the severe safety risks involved (such as accidentally damaging concealed electrical wiring or weakening the building’s structural integrity), HDB enforces strict rules. A licensed direct contractor handles the end-to-end compliance for you.
HDB Hacking Rules You Must Know
- Structural vs. Non-Structural Walls: You are strictly prohibited from hacking load-bearing structural walls, columns, or beams. These are usually indicated by thick, solid black lines on your HDB floor plan. Only non-structural walls (thin lines) can be demolished.
- Professional Engineer (PE) Endorsement: If your hacking works are extensive or close to structural elements, HDB may require a PE to assess and endorse your renovation plans before granting a permit.
- Approved Timing: Hacking is extremely noisy. HDB restricts demolition works to weekdays between 9:00 AM and 5:00 PM. No hacking is allowed on weekends or public holidays.
Average Hacking Costs Breakdown (2026)
Working with a direct contractor like Hock Star eliminates hidden fees. Here is what you are actually paying for:
| Type of Demolition | Estimated Cost | Notes |
|---|---|---|
| Floor Tiling Hacking | $3.00 – $5.00 psf | Includes hacking of existing ceramic/homogeneous tiles down to the concrete base. |
| Wall Hacking (Per Wall) | $400 – $800 | Cost depends on the length, thickness, and material of the non-structural wall. |
| Haulage & Debris Clearance | $500 – $1,500 | The cost to transport heavy rubble down from your unit and dispose of it legally at approved dumping grounds. |
Frequently Asked Questions (FAQ)
How long does it take to get an HDB hacking permit?
Once your direct contractor submits the floor plans and required documents, HDB typically processes and approves the hacking permit within 3 to 7 working days.
Can I overlay tiles instead of hacking them?
Yes. If you want to save money and time, overlaying vinyl or new tiles over your existing floor is a great alternative, provided the new floor thickness does not exceed HDB’s 50mm limit.
