A landed-home repaint can only look as good as the walls beneath it. When homeowners ask, “how much does it cost to plaster a landed house interior?” the useful answer is not a single number. It depends on whether you need local crack repairs, a skim coat to smooth existing walls, or a full cement plaster replacement after hacking. Those are very different scopes, timelines, and budgets.
For a landed property in Singapore, expect interior plastering to be quoted after an onsite inspection. Access, wall condition, ceiling height, moisture damage, and the total wall surface area can move the final figure significantly. A professional quote should make the scope clear before work begins, so there are no surprises halfway through preparation or painting.
How Much Does It Cost to Plaster a Landed House Interior?
As a practical starting point, skim coating and minor wall rectification may range from about S$1.50 to S$4 per square foot of affected surface. Full cement-sand plastering commonly costs more, often around S$4 to S$9 or more per square foot, depending on wall condition, thickness required, and access requirements.
These figures refer to wall surface area, not your home’s floor area. A 3,000-square-foot landed house can easily have 8,000 to 12,000 square feet of paintable wall and ceiling surface once bedrooms, stairwells, corridors, bathrooms, and feature areas are included. That is why a whole-house plaster scope can range from the low five figures for selective skim coating to S$30,000, S$50,000, or more for extensive hacking and full replastering.
If only selected rooms have hairline cracks, uneven patches, or old repair marks, the cost may be much lower. A contractor may price this as a localized repair package or quote by area. The key is to avoid paying for full replastering when proper patching, mesh reinforcement, skim coating, sealing, and repainting will solve the actual problem.
A realistic budget by scope
For light surface preparation across a landed home, including filling small cracks, patching nail holes, sanding rough areas, and spot skim coating, homeowners may set aside roughly S$3,000 to S$10,000 before painting. This is common for maintenance work where the existing walls are generally sound.
For broader skim coating to improve uneven internal walls, a typical budget can fall around S$12,000 to S$30,000, depending on the number of rooms and total treated area. This is often chosen before a high-quality repaint, especially when strong side lighting makes old roller marks, patchwork, or wavy walls more obvious.
For full hacking, substrate repair, mesh installation where needed, and new plaster application across large sections or the entire interior, costs can rise beyond S$30,000. Larger detached homes, double-volume living spaces, stairwell walls, and homes with widespread dampness may require a substantially higher allowance.
What changes the plastering price?
The biggest cost driver is the wall’s existing condition. Fresh, stable walls with minor cosmetic imperfections need a different level of work from old walls with hollow plaster, active cracks, water staining, or peeling coatings. A low quote can become expensive if the contractor only paints over defects that should have been repaired first.
Moisture is especially important. If a wall is damp because of a leaking pipe, failed waterproofing, roof seepage, or an exterior crack, plastering it immediately may only hide the issue for a short time. The moisture source should be identified and rectified first. Otherwise, new paint may blister and new plaster may fail.
Ceiling height and access also affect labor. A standard bedroom wall is straightforward. A double-height living room, stairwell, high void, or wall above built-in cabinetry requires more protection, ladders or scaffolding, and working time. Homes occupied during the work may need additional furniture wrapping, dust control, daily cleanup, and phased scheduling.
Material selection matters too. Basic patching compound is appropriate for small finishing repairs, while cementitious materials, fiberglass mesh, bonding agents, and moisture-resistant systems may be needed for deeper or recurring problems. The lowest material cost is not always the right choice for a wall that has already cracked more than once.
Finally, clarify whether the price includes painting after plaster repairs. Plastering, skim coating, priming, and applying two finish coats are separate stages, even if one contractor manages them as one project. A complete scope is easier to coordinate and helps ensure the repaired surface receives the correct sealer and paint system.
Plaster, skim coat, or crack repair: choose the right work
Many homeowners use “plastering” to describe any wall-smoothing work. Onsite, the right solution is usually more specific.
A localized crack repair is suitable for small, stable cracks and isolated damaged spots. The contractor opens and cleans the crack, applies the appropriate filler or repair compound, reinforces it where required, sands it smooth, seals the area, and repaints. It is the most efficient option when the problem is cosmetic and limited.
Skim coating is a thin finishing layer applied over a wall to improve flatness and texture. It is useful for walls with visible patch marks, old paint texture, light undulations, or a rough finish that will show through after repainting. It gives a cleaner base for modern matte and low-sheen paint finishes, which tend to reveal surface imperfections.
Full replastering is for failed or severely uneven surfaces. It may involve hacking away loose material, treating the substrate, applying a bonding layer, rebuilding the plaster, allowing proper curing, then finishing with skim coat and paint preparation. It takes longer, creates more dust, and costs more, but it addresses a deeper failure rather than disguising it.
What should a professional landed-house quote include?
Do not compare quotes by the final number alone. Compare the preparation standard, the repair method, and the handover commitment. For a landed interior, a clear quote should state which areas are being treated and whether pricing is based on estimated or measured wall surface area.
It should also explain whether the contractor will protect flooring, furniture, doors, windows, and built-in fixtures; hack and dispose of loose plaster where necessary; repair cracks with mesh or other reinforcement; sand between coats; apply sealer or primer; and perform touch-ups after painting. If the home is occupied, confirm the daily cleanup arrangement and whether work can be scheduled by floor or room to reduce disruption.
Ask about exclusions as well. Water leaks, waterproofing failures, electrical relocation, carpentry removal, and major masonry repairs are often separate trades. Clear exclusions protect both sides because they prevent a simple plaster quote from becoming an undefined renovation project.
A faster way to plan the work
Start with a site assessment before choosing paint colors or booking movers. The contractor should inspect walls in natural light, check for hollow or damp areas, identify cracks that need reinforcement, and separate essential repairs from optional cosmetic improvements. This lets you direct budget where it matters most.
Next, decide whether you are preparing for move-in, repainting an occupied home, or correcting defects after renovation. A vacant home allows faster work because there is less furniture protection and no need to phase rooms around daily routines. For occupied landed homes, a systematic room-by-room plan keeps the project organized and limits the mess to active areas.
Then request a fixed scope once the wall condition is confirmed. At Painting.com.sg, the team can coordinate surface preparation, crack patching, sealing, paint selection, multi-coat application, cleanup, and final touch-ups under one managed workflow. That means less time spent coordinating separate repair and painting crews, and clearer accountability for the finished walls.
A well-plastered wall is not an upgrade you notice only on handover day. It is what keeps your new paint looking smooth, even, and properly finished long after the furniture is back in place.
