Hacking is the first messy step of most renovations — tearing out old floor tiles, knocking down a partition wall, stripping a bathroom back to bare walls. It's priced two ways: **per element** (per psf for tiles, per wall for partitions) or as a **lump sum** for a full-flat strip-out after a site survey.Ballpark for 2026: floor tile hacking runs S$3–S$8 psf, a non-structural wall is S$400–S$900, and a full interior strip-out of a 4-room HDB is S$3,500–S$5,500. On top of that, haulage and disposal (carting the debris to an NEA-approved site) is S$300–S$1,500 depending on volume.
The one rule you cannot get around: structural walls, columns and beams can never be hacked without HDB written consent and a Professional Engineer's endorsement. If a contractor offers to knock one down without that paperwork — walk away. The liability is yours.
| Work | Typical cost | Notes |
|---|---|---|
| Floor tile hacking | S$3 – S$8 psf | Incl. basic disposal |
| Non-structural wall removal | S$400 – S$900 per wall | Depends on length/thickness |
| Bathroom strip-out | S$800 – S$1,800 per bathroom | Tiles + fixtures + disposal |
| Kitchen strip-out | S$500 – S$1,200 | Cabinets, tops, fixtures |
| Full 4-room HDB demolition | S$3,500 – S$5,500 | Whole interior |
| Haulage / disposal | S$300 – S$1,500 | Confirm if included |
Indicative 2026 ranges. Final price depends on material, access, floor level, protection and debris volume.
Why it's priced two ways
For a partial job — just the floor, or one wall — contractors price per element: per psf for tiles, per wall for partitions, per room for a false ceiling. Easy to compare.
For a full resale gut, where everything comes out, a lump-sum quote after a site survey is more common, because the crew, machinery and disposal scale with the whole job. Either way, ask for itemised, per-element pricing so you can see what's actually being charged — and so you can choose to keep a wall or fixture and trim the bill.
What the common jobs cost
| Element | Typical cost |
|---|---|
| Floor tile hacking | S$3 – S$8 psf |
| Non-structural (partition) wall removal | S$400 – S$900 per wall |
| Bathroom strip-out (tiles + fixtures) | S$800 – S$1,800 per bathroom |
| Kitchen strip-out (cabinets + tops + fixtures) | S$500 – S$1,200 |
| False ceiling removal | S$900 – S$2,500 per room |
| Wall reinstatement (rebuild a partition) | S$400 – S$1,200 per wall |
Material drives a lot of this: drywall is cheap to hack, brick and reinforced concrete much harder (and pricier). Embedded services — wiring, pipes inside the wall — add care and time.
Full-flat demolition
If you're gutting a resale flat completely — kitchen, bathrooms, built-ins, non-structural walls and false ceilings:
| Flat | Full interior strip-out |
|---|---|
| 3-room HDB | S$2,500 – S$5,000 |
| 4-room HDB | S$3,500 – S$5,500 |
| 5-room HDB | S$4,500 – S$6,500 |
Scope shifts the number — keep some walls or fixtures and it drops. A floor-tiles-only hack across a 3-room is roughly S$2,500–S$5,000 on its own, inclusive of disposal.
Haulage and disposal — don't assume it's included
Hacking generates a lot of waste, and getting it to an NEA-approved facility costs S$300–S$1,500 depending on volume. The trap: some contractors quote hacking-only and add disposal separately at S$300–S$800. Always confirm whether haulage is in the price or on top — it's one of the most common "surprise" line items.
The structural wall rule (read this twice)
You can remove non-structural partition walls with an HDB permit. You cannot touch structural walls, columns or beams — they hold the building up. Any structural change needs:
- HDB written consent,
- a Professional Engineer (PE) endorsement, and
- a BCA-registered contractor to carry it out.
If anyone offers to hack a structural wall without this, that's a hard no. Beyond the safety risk, the liability lands on you as the flat owner, and it can void insurance.
Can you skip hacking entirely?
Sometimes, yes. Overlaying new vinyl or tiles over a sound existing floor avoids hacking and haulage altogether — as long as the new thickness stays within HDB's 50mm limit. It's the single biggest saving available on a floor job. (See the flooring and tiling guides for when overlay works and when it doesn't.)
The costs people forget
- Disposal charged separately — confirm it's in the quote, not a S$300–S$800 add-on.
- High-floor / lift-access surcharge — getting debris down from a high floor can cost more.
- Protection & dust containment — good crews sheet up and contain dust; cheap ones don't.
- Embedded services — walls with wiring or pipes inside take longer (and need an electrician/plumber to disconnect first).
- Permit & PE fees — structural changes carry permit (~S$350) and engineering endorsement costs.
- Reinstatement — if you remove a wall then need to rebuild part of it, that's a separate S$400–S$1,200.
Rules worth knowing
- HDB hacking permit required for all hacking; your registered contractor applies.
- Structural walls/columns/beams: prohibited without HDB consent + PE endorsement + BCA-registered contractor.
- Condos follow MCST rules — noisy hacking is usually limited to weekday hours (often 10am–4pm).
- Unlicensed demolition can mean legal trouble, repair liability and voided insurance.
How to keep the bill sensible
- Overlay instead of hack where the existing surface is sound — biggest single saving.
- Keep what you can. Retaining a wall, a built-in or sound tiles trims the scope.
- Confirm haulage is included before you sign.
- Never entertain structural hacking without proper approval — it's not where you save money.
- Get 3 itemised quotes and benchmark per-element pricing.
