Professional disinfection in Singapore usually runs $120–250 for a 3-room HDB, $200–400 for a larger HDB or condo, and $400–900+ for a landed home, plus roughly $0.15–0.40 per sq ft for offices (minimum call-out around $250–450). You actually need it after an infectious illness like HFMD, COVID or stomach flu, or before a newborn or immunocompromised person comes home. For most other situations, a proper deep clean is enough.
That last point is the part most disinfection companies won’t say out loud. We’re Sureclean. We’ve cleaned over 50,000 homes across Singapore, we hold a 4.9-star rating from 1,476 Google reviews, and we run a dedicated disinfection service alongside our home and commercial cleaning. We’d rather you understand when disinfection is worth paying for than sell you a treatment you don’t need.
How much does disinfection service cost in Singapore?
Price comes down to three things: floor area, the method (ULV fogging is faster and cheaper than hand-wiping every surface), and urgency (a same-day emergency call-out costs more). Here are realistic market bands in Singapore:
| Property / space | Typical price range | What affects it |
|---|---|---|
| 3-room HDB | $120–250 | Floor area, fogging vs hand-wipe |
| 4/5-room HDB or condo | $200–400 | Number of rooms, high-touch detail |
| Landed / large home | $400–900+ | Multiple storeys, square footage |
| Small office unit | $250–450 (min. call-out) | Often priced per sq ft |
| Larger office / F&B | ~$0.15–0.40 per sq ft | Area, frequency, certificate |
Where do people quietly get overcharged? Two places. First, “per room” pricing that balloons once every wardrobe and toilet is counted as a “room”. Second, surprise certificate fees added at the end. A disinfection certificate should be part of a proper job, not an $80 extra. Always get the all-in number before you book. If your situation is unusual, say a whole shophouse, a clinic, or a childcare centre mid-outbreak, it’s case by case, so request a quote rather than trusting a flat online price.
Cleaning vs sanitising vs disinfecting: what’s the difference?
These three words get used interchangeably in Singapore, and that mix-up is exactly what makes people over- or under-spend. They are not the same thing.
| Term | What it does | Kills germs? |
|---|---|---|
| Cleaning | Removes dust, dirt and grime from surfaces | No, just removes them physically |
| Sanitising | Reduces bacteria to a “safe” level | Partially |
| Disinfecting | Destroys viruses and bacteria on surfaces | Yes, to a defined standard |
The key point: you have to clean before you disinfect. Disinfectant sprayed onto a dusty, greasy surface is mostly wasted, because the grime shields the germs underneath. This is why a freelancer who fogs a dirty flat in 15 minutes isn’t really disinfecting. He’s perfuming. Our crews wipe the high-touch points first, then disinfect.
When do you actually need professional disinfection?
Across our jobs in Singapore, the calls that truly warrant professional disinfection fall into a handful of clear triggers:
- HFMD (hand, foot and mouth disease). The big one. It rips through preschools and childcare centres, and the virus survives on toys, door handles and mattresses for days. A home with a young child who caught it is our most common residential disinfection job.
- A confirmed COVID, flu or stomach-flu (norovirus/rotavirus) case in the home or office. Norovirus is notoriously hardy and hard to kill with ordinary wiping.
- A newborn coming home, especially after a renovation.
- An elderly, immunocompromised or post-surgery family member moving in or back from hospital.
- A workplace with a positive case that needs staff back safely, often with a certificate to prove it.
The two people underestimate most? HFMD (they wipe the obvious toys but miss the mattress, sofa and aircon vents) and stomach flu (they assume Dettol handles it, and it often doesn’t). If you’re moving into a resale flat and don’t know the previous occupants’ health history, pairing disinfection with a proper move-in / move-out clean is a sensible one-time reset.
Can I just DIY it with Dettol, bleach or a UV lamp?
Sometimes, yes, and we’ll tell you so. If one person had a mild cold and you wiped down the door handles, taps, light switches and remotes with a proper disinfectant wipe, that’s reasonable. Save your money.
But DIY fails in specific, predictable ways we see all the time:
- Dettol used neat, or wiped off too fast. Most disinfectants need a contact (“dwell”) time, often several minutes wet on the surface, to actually kill the virus. Spray and immediately wipe does almost nothing. This is the single most common DIY mistake in Singapore.
- Bleach mixed with other cleaners. Bleach plus an acidic toilet cleaner or ammonia releases toxic chloramine gas, which is dangerous in a small, unventilated HDB bathroom.
- Shopee UV lamps. UV-C only works on surfaces in direct line of sight, at the right distance, for the right duration. It does nothing to the underside of a table or the inside of a fabric sofa, and cheap units are often underpowered. It is not a substitute for surface disinfection.
The other thing DIY can’t do is reach. A hand-wipe covers what you can see and touch. It won’t get behind furniture, into fabric, or evenly across a whole 5-room flat, which is where fogging earns its keep.
What we spray, and is it safe for babies, pets and food surfaces?
This is the first question we get from parents in small flats, and it’s a fair one. We use NEA-registered, hospital-grade disinfectants that are safe around children, pets and food-contact surfaces when applied correctly. Our default chemistry is eco-friendly and child- and pet-safe, and we’ll happily tell you exactly what’s being sprayed in your home. A company that won’t name its disinfectant is a red flag.
Two methods do the heavy work:
- ULV (ultra-low volume) fogging breaks disinfectant into a fine mist that settles evenly across large areas and reaches gaps a cloth can’t: under beds, across fabric, into corners.
- Electrostatic spraying charges the droplets so they wrap around and cling to surfaces, including the undersides and backs of objects. It gives the most even coverage.
We pair fogging or electrostatic spraying with hand-wiping of every high-touch point: handles, switches, taps, remotes, phones. That’s where transmission actually happens. A cheap operator skips the hand-wiping entirely, and you’d never spot the difference on the day, only in the result.
Disinfection certificates for offices, landlords and MOM/ECDA
For any commercial or office space, the certificate is often the whole point. Landlords, insurers, MOM, and ECDA-licensed childcare operators frequently want documented proof that a professional disinfection was done, including the date, area treated, method and disinfectant used. We provide a proper certificate as part of commercial disinfection jobs. If you’re told a certificate costs extra or “isn’t available”, treat that as a warning sign.
How to prepare, and the red flags to watch for
Before the team arrives, a little prep helps and a little over-prep hurts:
- Do: clear clutter off surfaces, put away loose food, unplug and switch off sensitive electronics if fogging is planned, and tell us about pets, fish tanks and anyone with asthma.
- Don’t: scrub everything with bleach the night before (you’ll just add chemical residue), and don’t lock food and toothbrushes inside sealed cabinets you then want disinfected. Tell us what needs treating.
After treatment, most rooms need roughly 30 minutes to 2 hours to dwell and ventilate before re-entry, depending on method and product. We’ll give you a specific re-entry time on the day.
Red flags when hiring a disinfection company in Singapore:
- No named disinfectant, or “secret formula” answers.
- Gig freelancers with no employed, trained, insured staff, so no accountability if something goes wrong.
- A suspiciously fast “spray-and-go” with no cleaning or hand-wiping step.
- No certificate offered for commercial jobs.
- Prices that only add up until the extras appear.
Everything we do is delivered by directly employed, trained and insured crews, not subcontracted gig workers. That’s why we can stand behind both the result and the paperwork.
Frequently Asked Questions
How much does disinfection cost for a 3-room HDB in Singapore? Expect roughly $120–250 for a 3-room HDB, depending on whether it’s fogging-based or a full hand-wipe treatment, and whether you need same-day service. Larger flats and condos typically run $200–400. For an exact figure, request a quote.
Do I really need to disinfect my whole home after my child gets HFMD? Yes, if you want to stop it spreading. The HFMD virus lingers on toys, mattresses, sofas and door handles for days. Treat the whole home, not just the visible toys. The surfaces people miss are exactly how siblings catch it next.
Is professional disinfection worth it, or is Dettol enough? For a mild cold, wiping high-touch points with disinfectant is often enough, so save your money. For HFMD, stomach flu, COVID or an immunocompromised household member, professional disinfection reaches fabric, undersides and whole-home coverage that hand-wiping and DIY sprays can’t, and with the correct dwell time.
What disinfectant do you use, and is it safe for babies and pets? We use NEA-registered, hospital-grade, child- and pet-safe disinfectants applied by trained crews. Used correctly, they’re safe around crawling babies, pets and food-prep surfaces. We’ll tell you exactly what we’re spraying.
Can I get a disinfection certificate for my office or landlord? Yes. We issue a proper disinfection certificate for commercial jobs, showing the date, area, method and product used, and it’s accepted by most landlords, insurers, MOM and ECDA-licensed operators.
How soon can I re-enter a room after disinfection? Usually 30 minutes to 2 hours, depending on the method and product, to allow proper dwell time and ventilation. We give you a specific re-entry time before we leave.
Still not sure whether you need it?
If you’re looking at a sick household or a positive case at the office and can’t tell whether to book disinfection or just a thorough clean, tell us the situation and we’ll give you an honest answer, even if that answer is “a deep clean is enough”. Have a look at our disinfection service, or if this is really about a fresh start in a new space, our general home cleaning and post-renovation cleaning teams can help. Request a quote and we’ll scope it properly.
