Deep cleaning HDB Singapore is tougher than most homeowners expect — years of humidity, cooking grease, and bathroom mould work their way into grout lines, cabinet hinges, and behind appliances in ways a regular mop-and-wipe session simply cannot fix. Whether you’re in a resale flat that needs a proper reset, a new BTO that just completed renovation, or a condo that hasn’t had a serious scrub in over a year, the approach needs to be systematic. Our team at Doctor Clean has cleaned hundreds of HDB units across Singapore, and this room-by-room guide is exactly what we follow on every job.
Step 1 — Start With the Kitchen (Grease First, Always)
Our team always begins in the kitchen because grease and carbon buildup are the most time-consuming problems in any Singapore HDB — and they contaminate everything if you leave them until the end. We degrease the range hood filter, the hood interior, and the hob surround using a commercial-grade degreaser, letting it dwell for several minutes before scrubbing. Cabinet exteriors, especially those above the hob, get wiped down with a microfibre cloth to pull off the sticky film that builds up from daily cooking. The area behind and beneath the refrigerator is always grimier than clients expect, so we shift it out and vacuum and mop underneath before moving on.
Step 2 — Tackle Every Bathroom From Ceiling to Floor
Singapore’s humidity means HDB bathrooms develop mould and soap scum faster than almost anywhere else — and surface wiping does not remove it. During our deep cleaning sessions, we work top to bottom: exhaust fan grilles, wall tiles, shower screens, toilet bowl inside and out, vanity cabinet surfaces, and finally the floor and floor trap. We pay close attention to silicone sealant lines around the basin and shower tray, where black mould hides even when everything else looks clean.
- Exhaust fan cover removed and scrubbed separately
- Grout lines along wall tiles scrubbed with a stiff brush
- Floor trap cleared and deodorised
- Toilet base and pipe connections wiped and disinfected
- Shower screen squeegeed and polished to remove limescale
“One key insight from Doctor Clean — never spray disinfectant and wipe immediately. Most products need at least 30 seconds of dwell time on the surface to actually kill bacteria and mould spores, not just smear them around.”
Step 3 — Bedrooms, Wardrobes, and Aircon Units
In the bedrooms, our team focuses on areas that regular housekeeping misses: the tops of wardrobe panels (a dust trap in every HDB), the tracks of sliding wardrobe doors, window grille frames, and skirting boards along every wall. We vacuum the mattress surface and sides before wiping down the bed frame. Aircon units deserve special attention — we wipe down the casing and louvers and remove and rinse the filters if the client has not had them serviced recently. If there is significant mould or odour coming from the unit itself, we recommend a professional aircon chemical wash separately, as that falls outside cleaning scope. For units with heavy soft furnishings, our upholstery cleaning service can be bundled in — any two pieces start from S$158.
Step 4 — Living Room, Floors, and Final Detail Pass
The living room is last because dust and debris from every other room eventually settles here. Our team wipes down all light switch plates, power socket covers, door frames, and skirting boards before moving to the floors. For tiles or vinyl plank flooring that has not been machine-scrubbed in over a year, we strongly recommend adding our floor scrubbing add-on — available from S$88 when bundled with a deep clean — because a mop simply cannot remove the embedded grime in grout channels or the dull film on older vinyl. Windows and grilles get a wipe-down on the interior side as part of our standard pass; for full exterior window cleaning in higher-floor HDB units, that is a separate service starting from S$200. Once every surface is done, we do a final walkthrough with the homeowner to flag anything before we pack up.
Frequently Asked Questions
How much does a deep cleaning HDB Singapore session cost?
Doctor Clean prices deep cleaning by hours for most HDB sizes. A 3-hour session starts at S$300 and covers units up to roughly 500–700 sqft. A 4-hour session is S$350, 5 hours is S$400, and larger flats like 5-room or executive HDB typically need 6–8 hours, priced between S$500 and S$700. You can check the full breakdown on our pricing page.
What is the difference between spring cleaning and a deep clean?
At Doctor Clean, both services follow the same thorough room-by-room process — the difference is mainly in how homeowners describe their need. Our spring cleaning service is the same deep, detailed clean we do before Chinese New Year, after renovation, or whenever a flat needs a full reset. The scope covers all rooms, all surfaces, and all the hard-to-reach areas a regular session skips.
Do I need to be home during the deep clean?
You do not have to be present throughout, but we recommend being available at the start so our team can walk through the flat and flag any specific concerns, and again at the end for the final check. Most clients hand us the keys and return when we notify them we are done — we are fully insured and have cleaned thousands of Singapore homes.
Can I add formaldehyde removal for a new BTO flat?
Yes, and we recommend it for any HDB that has recently completed renovation or had new furniture delivered. Our formaldehyde removal service can be added on from S$88 when bundled with a deep clean, or booked as a standalone service starting from S$100 for smaller flats. New timber furniture, laminate surfaces, and fresh paint all off-gas formaldehyde for months after installation.
How often should an HDB be deep cleaned?
Our general recommendation for Singapore HDB units is once every 6 to 12 months for a thorough deep clean, on top of regular housekeeping. Households with young children, pets, or anyone with respiratory sensitivities benefit from doing it every 6 months. Between sessions, our regular housekeeping packages from S$90 per session help maintain the standard without letting grime build back up.
