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.
Regular 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 does not usually reach. Here's what it covers and how to set a sensible frequency for your household.
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.
- Cleaning small areas of surface mould on silicone or ceilings. Wear the protection stated on the product label, ventilate the room and follow the manufacturer's instructions. Recurring mould, damp or bulging finishes need the moisture source checked first. The NEA home-cleaning guide explains ventilation, PPE and safe product use.
- 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 | Review every 3–6 months | Book when grease, limescale or high dust has built up beyond the weekly clean. |
| Pets, allergies, heavy cooking or poor ventilation | Review more often | Use the visible build-up and household needs, not a fixed calendar, to set the interval. |
| Moving or post-renovation | One-off | Use the dedicated scope for move-in/out grime or renovation dust. |
The 3–6 month review is a practical starting point, not a national rule. A festive reset is what many people mean by a spring clean — same kind of whole-home scope, 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 periodic reset for filters, grout, surface mould and high dust your weekly clean skips. Review the need every 3–6 months, then adjust for the way your household uses the home.

Frequently asked questions
- How often should I deep clean my HDB flat?
- There is no official frequency for every home. Reviewing the need every 3 to 6 months is a practical starting point, then adjust for household size, pets, allergies, heavy cooking, ventilation and visible grease, scale or high dust. Moving and post-renovation cleans are separate one-off scopes.
- 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?
- As at 31 July 2026, SparkFlow's deep-clean starting prices are $420 for a 3-room HDB or condo, $520 for a 4-room and $620 for a 5-room. Studios start at $280 and 2-room units at $340. Condition, access, furniture and add-on work can change the final quote.
