A professional deep clean in Singapore typically costs $250–$500 for an HDB flat, $400–$800 for a condo, and $700 upwards for landed homes. It’s a top-to-bottom, room-by-room scrub of the build-up a weekly clean never reaches — window tracks, grilles, grout, hood grease and aircon vents.
That’s the short answer. The longer one matters, because “deep cleaning” is one of the most abused words in this trade — the gap between a real deep clean and a glorified wipe-down is exactly where people get burned. We’ve cleaned 50,000+ homes across Singapore at a 4.9-star rating from 1,476 Google reviews, so here’s the honest version: real price bands, what’s genuinely included, what quietly gets skipped, and how to spot a spray-and-pray crew before you pay them.
How much does a deep clean cost in Singapore?
Deep cleaning is priced on home size and condition, not a flat rate. Here are realistic 2026 market ranges for a one-time deep clean:
| Home type | Typical market range (one-time deep clean) |
|---|---|
| 3-room HDB | $250–$400 |
| 4-room HDB | $300–$500 |
| 5-room / executive HDB | $400–$650 |
| Condo (2–3 bedroom) | $400–$800 |
| Landed / large condo | $700–$1,500+ |
A few things move the number inside those bands:
- Empty vs lived-in. An empty unit before move-in is faster and cheaper than a fully furnished, occupied home where we work around your furniture, wardrobes and belongings.
- Condition. A maintained flat and one with years of baked-on kitchen grease, mould in the bathroom silicone, or a tenant who just moved out are not the same job.
- Add-ons. An aircon chemical wash, external high-window work, and upholstery (sofa, mattress, curtains) sit outside a standard deep clean and are quoted separately.
Some operators charge by the hour instead — usually $35–$50 per hour per cleaner for a team. That can look cheaper on paper, but an hourly job with no fixed scope is where “we ran out of time, the aircon and windows weren’t included” happens. For an exact figure, send photos plus your floor size and request a quote rather than trust a price given blind over the phone.
What’s actually included in a professional deep clean?
A real deep clean is systematic and room-by-room. When our crews run a full deep clean, the checklist looks like this:
Kitchen — degreasing the hood, hob and backsplash tiles (the sticky yellow film from years of wok-frying), wiping cabinet fronts and interiors on request, scrubbing the sink and taps, and cleaning behind and beside appliances where grime collects.
Bathrooms — descaling glass and taps, scrubbing grout lines and floor traps, treating mould on silicone seals, and disinfecting the whole toilet.
Bedrooms & living areas — high dusting (ceiling fans, aircon trunking, top of wardrobes and door frames), wiping skirtings and ledges, cleaning window tracks and grilles, internal glass, switches and full floor treatment.
The spots the weekly cleaner never touches — window casement grooves, aircon vents and fan blades, the tops of high cabinets, and the HDB service yard. That’s the whole point of a deep clean.
Now the honest part — what a standard deep clean does NOT include unless you add it on: aircon *chemical* wash (opening up the unit), cleaning external windows on high floors, sofa/mattress/curtain extraction, and heavy mould remediation. Any company promising “everything’s included” at a suspiciously low price is planning to skip something.
Deep clean vs spring clean vs regular clean — which do you need?
These three get mixed up constantly, and booking the wrong one wastes your money.
| Service | What it’s for | How often |
|---|---|---|
| Regular / weekly clean | Maintenance — floors, surfaces, toilets, kitchen wipe-down | Weekly or fortnightly |
| Deep clean | Reset — everything above plus the neglected build-up (tracks, grilles, grout, hood grease) | Every 3–6 months |
| Spring clean | The most thorough — a deep clean scoped larger, often pre-CNY or seasonal, frequently with add-ons | 1–2× a year |
If a cleaner already visits and you just want a periodic reset, a deep clean is right. If you want ongoing upkeep so it never gets bad again, that’s weekly home cleaning. If it’s the big annual overhaul before Chinese New Year or a special occasion, look at professional spring cleaning. And if you’re handing back a rental or receiving keys, that’s a move-in / move-out clean, which runs to its own handover-standard checklist.
How long does it take, and how many cleaners come?
This is where DIY expectations fall apart. People imagine one person finishing a whole flat in two hours — that’s a wipe-down, not a deep clean.
Realistically, a proper deep clean needs a team, not a solo cleaner:
- 3–4 room HDB: roughly 3–5 hours with a 2–3 person crew
- 5-room / executive HDB: 4–6 hours
- Condo / landed: half a day or more, with a larger team
Sending a trained crew together isn’t upselling — it’s the only way to hit every item on the checklist in one visit without cutting the neglected areas to “finish on time”.
Is deep cleaning worth it, or can you DIY?
Be honest with yourself about two things: your time, and your equipment.
You *can* DIY the visible surfaces. Where it falls apart is the built-up stuff — grout, hood grease, window tracks, and anything needing a proper vacuum, extraction machine or the right chemical for the surface. We’re regularly called in to redo a cheap job booked off Carousell or Facebook: the floors looked mopped, but the tracks were still black, the hood was still sticky, and the “mould treatment” was a spray that faded by the next week.
The real difference isn’t the mop — it’s the crew and the accountability behind it. Ours are directly employed, trained and insured staff, not gig freelancers with a rented machine. Every job gets supervisor QC and documented before/after photos, so you can actually see what was done. If something breaks, you’re covered — not chasing a stranger who’s blocked your number.
Our honest take: if you have the weekend and a proper vacuum, do the surfaces yourself. Pay a professional for the reset — the grease, the grout, the tracks, the height — because that’s where equipment, technique and time genuinely change the result.
How often should you deep clean in Singapore’s humidity?
Singapore does specific damage that dry countries don’t. Our humidity breeds dust mites in mattresses and soft furnishings, feeds black mould in bathroom silicone and behind wardrobes, and leaves that musty, closed-room smell in units that sit shut with the aircon off. Add fine renovation dust drifting from a neighbour’s unit into your aircon ledges and window tracks, plus the oily film behind the stove, and build-up here is faster than most people expect.
For that reason we generally recommend a deep clean every 3–6 months for a typical home, tighter if you have pets, an allergy sufferer, or heavy home cooking. A deep clean *can* physically remove mould spores, dust-mite build-up and the grime causing a musty smell — but if there’s an underlying moisture problem (a leak, no ventilation), the mould will return no matter how well we scrub. We’ll tell you that straight rather than sell you a clean that won’t hold.
Persistent cooking, incense or off-gassing furniture smells are a separate problem. Surface cleaning helps, but genuine odour and air-quality issues usually need targeted disinfection or specialised treatment, and a fresh-renovation chemical smell needs proper post-renovation cleaning plus time for the new material to off-gas — no amount of scrubbing shortcuts that.
Red flags: how to choose a deep cleaning company
After 50,000+ homes, these are the warning signs we’d tell our own family to watch for:
- A firm fixed price with no photos or floor size asked. A real quote depends on condition. A blind price means someone’s guessing — and will “adjust” on the day.
- No mention of QC, supervision or before/after photos. If nobody’s checking the work, nobody’s doing the hard-to-reach parts.
- No insurance, no company entity, cash-only, contactable only on a personal chat. If they scratch your parquet or crack a basin, you have zero recourse.
- “Everything included” at a rock-bottom price. Aircon chemical wash and external high windows cost real labour. If it’s suspiciously cheap, those are exactly what gets silently dropped.
- Vague on equipment. A proper crew brings commercial vacuums, extraction gear and the correct chemical per surface. A freelancer with a bucket and one all-purpose spray cannot deliver a deep clean — and the wrong chemical can permanently damage marble or parquet.
You supply nothing but access and power — a real company brings its own tools, machines and child- and pet-safe chemicals. If they’re asking you to provide the vacuum and detergent, that tells you what kind of operation it is.
Frequently Asked Questions
How much does a deep clean cost for a 4-room HDB in Singapore? Expect a market range of roughly $300–$500 for a one-time deep clean of a 4-room HDB. The final price depends on whether the flat is empty or furnished, how much built-up grease and mould there is, and any add-ons like aircon chemical wash. For an accurate figure, send photos and request a quote.
What’s the difference between deep cleaning and spring cleaning? A deep clean is a thorough top-to-bottom reset covering neglected areas like window tracks, grilles, grout and hood grease. A spring clean is essentially a deep clean scoped even larger — usually seasonal (pre-Chinese New Year) and often bundled with add-ons like curtain, sofa or mattress cleaning.
How long does a deep clean take and how many cleaners come? A 3–4 room HDB usually takes about 3–5 hours with a 2–3 person crew; larger condos and landed homes take half a day or more with a bigger team. A single cleaner finishing a whole flat in two hours is a wipe-down, not a deep clean.
Can a deep clean remove mould and the musty humid smell? Yes — a proper deep clean removes mould spores, dust-mite build-up and the grime causing musty odours. But if there’s an underlying moisture or ventilation problem, the mould will come back. That root cause needs fixing before cleaning can hold.
Do I need to provide equipment and chemicals? No. A reputable company brings its own commercial vacuums, extraction machines and the correct chemical for each surface, using child- and pet-safe products. If a cleaner asks you to supply the tools and detergent, treat that as a red flag.
Is deep cleaning worth it, or should I just DIY? DIY the visible surfaces if you have the time and a decent vacuum. Pay a professional for the reset — grout, hood grease, window tracks and high areas — where the right equipment, technique and manpower genuinely change the result, and where a rushed cheap job usually needs redoing anyway.
Ready for a proper reset?
A deep clean should leave your home genuinely reset — tracks, grout, grease and all — not just look tidy for a photo. If you’d like an honest, itemised quote based on your actual home rather than a blind phone number, tell us about your place and we’ll scope it properly. Directly employed, trained, insured crews, documented before-and-after QC, and a straight answer on what your home actually needs.
