The Quick Answer: Hacking Works Singapore 2026

Hacking works are among the most disruptive yet essential parts of any Singapore renovation — understanding what they involve, what approval is needed, and how long they take can save you significant stress. Whether you are opening up a floor plan, relaying bathroom tiles, or removing old built-in structures, hacking is almost always the first phase of a renovation and the one that sets the pace for everything that follows. This guide explains hacking works in plain terms for Singapore homeowners.

Key Considerations for Hacking Works Singapore in Singapore

What Are Hacking Works in Singapore Renovation?

In the context of Singapore renovation, “hacking” refers to the controlled demolition and removal of existing building materials and finishes. It encompasses the breaking down of tiled floors and walls, the removal of existing plaster, the demolition of non-structural partition walls, the breaking up of concrete screeds and floor bases, and the removal of built-in fixtures such as kitchen cabinets, bathroom fittings, and built-in wardrobes that are physically bonded to the building structure.

The term is used broadly across the Singapore renovation industry and covers anything from the simple removal of a single tiled wall in a bathroom to a comprehensive whole-flat strip-out in preparation for a complete renovation. The scope of hacking works directly determines the volume of debris to be disposed of, the amount of dust and noise generated, and the time required before other renovation trades can begin their work.

Types of Hacking Works

Wall hacking involves the removal of wall tiles, plaster, or entire partition walls. Non-structural partitions — typically lightweight block walls or drywalls — can be hacked relatively straightforwardly. Structural walls — those shown in bold on HDB floor plans or identified by a Professional Engineer for private properties — require a formal assessment and, in HDB flats, explicit HDB approval before any hacking proceeds. The consequences of hacking a structural wall without proper authorisation are severe, and any reputable contractor will refuse to carry out such work without the necessary approvals in place.

Floor hacking refers to the removal of existing floor finishes — tiles, marble, timber, or vinyl flooring — along with the adhesive screed or mortar bed beneath. In Singapore’s older HDB flats, original floor tiles are often laid directly onto the concrete slab. Their removal generates considerable dust and requires pneumatic chisels or angle grinders. In more recently built properties, tiles may be laid on a raised screed that must also be removed if a new tile or floor level is being established.

Ceiling hacking encompasses the removal of existing false ceiling boards, timber battens, metal frames, and any associated electrical cabling and fittings. Ceiling hacking is less physically demanding than floor or wall hacking but generates significant quantities of lightweight debris that must be carefully managed to avoid contaminating other works. In properties with asbestos-containing materials in older ceiling boards — a risk in pre-1990s buildings — specialist removal is required and must be handled by a licensed contractor.

When Are Hacking Works Required in a Renovation?

Hacking is required whenever existing finishes or structures need to be removed to allow new works to proceed correctly. In bathroom renovations, all existing wall and floor tiles must typically be hacked back to the substrate before new waterproofing and tiling can begin. Attempting to lay new tiles over old tiles — a practice sometimes offered as a cost-saving measure — risks uneven surfaces, compromised adhesion, and failure of the new tile installation within a few years.

For open-plan renovation concepts where homeowners want to remove partition walls between living and dining areas, or between bedrooms and corridors, hacking works are the enabling step. In kitchen renovations, the removal of old cabinets, tiles, and often the entire wet area screed is standard practice before a new kitchen layout is established. Similarly, a full BTO renovation — where new HDB owners want to remove the basic fittings provided by HDB — starts with a comprehensive hacking phase.

HDB Rules for Hacking Works

HDB’s renovation guidelines impose clear requirements on hacking works in HDB flats. All hacking works must be carried out by a registered HDB Renovation Contractor, and a renovation permit must be obtained before hacking begins. Hacking hours are strictly regulated: noisy works are permitted only between 9:00am and 5:00pm on weekdays and Saturdays. No hacking is permitted on Sundays or public holidays.

Structural walls — marked in bold on the original HDB floor plan — cannot be hacked without explicit HDB approval and a Professional Engineer’s assessment. In practice, HDB rarely approves structural wall removal in standard flat types, and homeowners should treat any contractor who offers to hack structural walls without these approvals as a serious red flag. Additional structural elements — including beams, columns, and the concrete floor slab — are similarly protected and cannot be hacked without formal assessment and approval.

How Much Do Hacking Works Cost in Singapore?

Hacking works costs in Singapore are typically quoted per unit area or per linear metre depending on the type of work. Floor tile hacking is commonly priced at $3 to $8 per square foot depending on the number of tile layers, the hardness of the adhesive, and the thickness of the screed. Wall tile hacking runs similarly at $3 to $7 per square foot. Partition wall demolition is typically priced at $300 to $800 per wall depending on construction type and wall thickness.

Debris disposal is a significant and sometimes overlooked cost element. All demolition waste must be properly bagged, transported, and disposed of at licensed facilities. Responsible contractors include disposal costs in their hacking quotation; those who exclude it are effectively passing an uncertain cost onto you. For a complete HDB three-room flat hacking scope — all bathroom tiles, all floor tiles throughout, and two to three partition walls — total hacking and disposal costs typically range from $3,000 to $7,000 depending on the extent of works.

How Long Do Hacking Works Take?

The duration of hacking works depends entirely on scope. A single bathroom hack-and-prepare — removing all wall and floor tiles and preparing the substrate for waterproofing — typically takes two to three days for a standard HDB bathroom. A full flat hack across all bathrooms, kitchen, and floor finishes throughout a four-room HDB flat typically takes five to eight working days, including debris clearing.

Partition wall demolition adds time depending on the construction type and the volume of debris. Planning your renovation timeline should include the full hacking phase plus a day or two for dust settlement and substrate inspection before wet works begin. Rushing hacking to save time creates problems downstream — inadequate substrate preparation is one of the leading causes of premature tile failure in Singapore renovations.

Why Hire a Professional Contractor for Hacking Works in Singapore

Hacking appears straightforward from the outside — it is, after all, demolition. But the consequences of poor hacking execution range from the inconvenient to the seriously expensive. Hacking too aggressively into a concrete floor slab can damage embedded electrical conduits or water pipes, requiring costly repairs before the renovation can proceed. Failing to adequately waterproof after floor hacking allows moisture to migrate through the slab to the unit below, creating neighbour disputes and liability that can drag on for months.

A professional contractor with proper equipment — industrial dust extraction systems, the correct chisel profiles for different tile substrates, and proper debris management procedures — completes hacking works faster, cleaner, and with less collateral damage than an inexperienced team. This matters in Singapore’s dense residential environment, where minimising dust, noise, and disruption to neighbours is both a regulatory requirement and a social obligation.

Conclusion: Hacking Works Done Right Set the Foundation for Everything That Follows

Hacking is where every renovation begins, and the quality of the hacking phase determines the quality of everything built on top of it. Skimping on hacking — leaving old tile adhesive on walls, inadequately preparing floor substrates, or failing to remove compromised screed — creates defects in the finished renovation that are costly and disruptive to rectify. Engaging a registered, experienced contractor for your hacking works is not optional — it is the foundation of a renovation that lasts.
