HDB deep cleaning: what it covers and how often you need it
Your weekly clean keeps the surface tidy; a deep clean gets the grease, limescale and dust that build up out of reach. Here's exactly what a deep clean covers, and how often a Singapore home actually needs one.
SparkFlow team5 min readRegular cleaning keeps a home looking decent week to week. A deep clean is different — it's the periodic reset that tackles the grease, limescale, mould and dust that ordinary cleaning never reaches. Here's what it actually covers and how often you need one.
What a deep clean covers (beyond the weekly)
Kitchen
- Degreasing the hood filter, hob and tiled backsplash.
- Inside the oven, microwave and fridge.
- Wiping cabinet interiors and the tops of high cabinets.
Bathrooms
- Descaling taps, glass and showerheads; scrubbing grout.
- Treating mould on silicone and ceilings.
- Clearing drains and wiping the exhaust-fan cover. A deep clean shifts surface gunk, but a drain that's genuinely slow needs a proper clogged-drain clearance rather than a wipe-down.
Whole home
- Dusting ceiling-fan blades, light fittings and the tops of wardrobes and doors.
- Cleaning window panes, grilles and tracks.
- Wiping skirting, switch plates and door frames.
- Cleaning aircon filters and front panels (a full aircon chemical wash is separate).
How often?
| Situation | Frequency | Why |
|---|---|---|
| Most HDB homes | Every 3–6 months | Keeps grease, limescale and high dust build-up in check. |
| Before Chinese New Year / festive season | Once a year | The traditional annual reset before the festive period. |
| Moving, post-renovation, or a new baby | One-off | Deep cleans at the moments that matter most. |
That festive reset is what most people mean by a spring clean — same checklist, just timed to the calendar. If you're moving in rather than out, the move-in clean gets the previous owner's build-up out before your furniture lands.
After a renovation specifically, the dust is a different beast — fine cement and sanding dust gets everywhere, which is why a dedicated post-renovation cleaning is a separate job. See our post-renovation cleaning checklist for that. Moving out? The move-out checklist is the version landlords inspect against.
The takeaway
Deep cleaning is the reach-the-unreachable reset every 3–6 months — the filters, grout, mould and high dust your weekly clean skips. If you'd rather hand it over, our cleaning team runs the full checklist above; WhatsApp us your flat size for a quote.
Frequently asked questions
- How often should I deep clean my HDB flat?
- Most HDB homes need a deep clean every 3 to 6 months to keep grease, limescale, mould and high dust in check. Many households add an annual reset before Chinese New Year, plus one-off deep cleans around moving, post-renovation, or welcoming a new baby.
- What is the difference between regular cleaning and deep cleaning?
- Regular cleaning keeps surfaces tidy week to week. A deep clean is a periodic reset that reaches what ordinary cleaning never touches: degreasing the hood filter and oven, descaling taps and showerheads, scrubbing grout, treating mould, and dusting fan blades and the tops of wardrobes.
- Does a deep clean include aircon servicing?
- A deep clean covers your aircon filters and front panels, but a full chemical wash is a separate job. The deep clean wipes and rinses the accessible parts; a chemical wash dismantles the unit to clear the coil and drainage, which is booked as its own aircon service.
- Do I need a deep clean after renovation?
- Yes. Renovation leaves fine cement and sanding dust everywhere, which is heavier than ordinary build-up and needs a dedicated post-renovation clean rather than a standard deep clean. It is worth booking before you move furniture in, so the dust does not settle into your new space.
- How much does HDB deep cleaning cost in Singapore?
- Pricing depends mainly on your flat size and the scope of work, so the simplest way to get an accurate figure is to send us your flat size for a quote. SparkFlow's cleaning team runs the full room-by-room deep clean checklist, from kitchen degreasing to bathroom descaling and whole-home dusting.
