Mould removal in Singapore typically costs from about $250 for a small area to $2,500 or more for larger or severe cases, depending on the size, severity and whether anti-mould coating is needed. Four Solutions gives a clear price after a quick assessment or a photo.
Mould removal in Singapore typically runs from around $250 for a small single patch to $2,500 or more for whole-home or severe, multi-room cases. We price the actual scope rather than a flat rate, so you are not overpaying for a small job or under-treating a large one. The fastest way to get a real figure is to send photos of the affected area for an estimate.
Mould removal price guide
| Scope | Typical cost |
|---|---|
| Single ceiling or wall patch | from around $250 |
| One room (walls, ceiling and corners) | mid-range |
| Multiple rooms, wardrobes or whole home | up to $2,500 or more |
| Replastering, if needed | $80 to $150 per affected area |
These are guide figures. Because mould severity varies so much, the honest way to price it is from a photo or a short site check, not a fixed menu.
What affects the cost
- Affected area and severity. A single ceiling patch costs far less than whole-room or multi-room treatment.
- The cause. Surface condensation is quicker to treat than mould fed by a hidden leak or seepage, which needs the moisture source addressed first.
- Anti-mould painting. An optional odourless anti-mould coating after removal adds to the scope where you want lasting protection.
- ULV fogging. An optional add-on for airborne spores or full-room decontamination.
- Repairs. If replastering is needed it is charged separately, typically $80 to $150 per affected area.
Why the cheapest quote often costs more
A low quote that only paints over mould hides the stain for a few weeks, then it returns and you pay again. Treating the moisture source and the mould together costs a little more once, and it deals with what is feeding the growth. Whether mould comes back still depends on the moisture or leak behind it and on the conditions in the room, which is why we assess the cause rather than only the stain.
What is included
Standard treatment includes professional biocide application, dwell time, physical removal of dead mould and a wipe-down of affected surfaces. Selected work can be warranty-backed: the written quotation confirms whether a warranty applies, its duration, the work it covers, the exclusions and the follow-up conditions. Four Solutions holds NEA Vector Control Operator registration (Reg. NEA201812722M), which covers pest control work and is not a mould certification.
Mould removal cost FAQs
How much does mould removal cost in Singapore?
Most residential jobs range from around $250 for a small patch to $2,500 or more for whole-home or severe cases, depending on the area, the severity and whether anti-mould painting or fogging is included. You always know the price before we start.
Why does the price vary so much?
Because mould severity varies. A single condensation patch on a ceiling is a small job, while mould fed by a hidden leak across several rooms needs the moisture source fixed first and far more treatment.
Do you charge for a quote or site visit?
Send photos on WhatsApp and we can usually quote from those at no charge. A site assessment is arranged only for larger or hidden cases, and any fee for that visit is confirmed with you before booking.
Is anti-mould painting included in the price?
It is an optional add-on. Where you want lasting protection, an odourless anti-mould coating is applied after removal and added to the scope.
Is it cheaper to remove mould myself?
For a small surface patch, DIY cleaning is cheaper. But if it keeps returning, the moisture source is the real cost, and repeated DIY plus repainting usually adds up to more than treating it properly once.
Does ceiling mould cost more than wall mould?
Not necessarily. Cost follows the area and the cause, not the surface. Ceiling mould often points to aircon condensation or a leak.
Do you offer a warranty at these prices?
Warranty availability depends on the assessed scope and the finishing system used. The written quotation confirms whether a warranty applies, its duration, the work it covers, the exclusions and the follow-up conditions.
