Post-construction cleaning in Singapore is a specialised service that handles the aftermath of major building works — new HDB BTO handover, condo project completion, commercial fit-out, or extensive A&A renovation. It’s not the same as regular deep cleaning, and it’s not the same as post-renovation cleaning either. Here’s the 2026 guide to what post-construction cleaning actually involves, when you need it, and what it costs in Singapore.
What is post-construction cleaning?
Post-construction cleaning is the final phase of cleaning after major construction, structural work, or extensive renovation is complete. It bridges the gap between construction handover and move-in / occupancy. The scope specifically targets construction-grade residue:
- Cement dust (microscopic particles that embed in porous surfaces)
- Tile adhesive and grout haze
- Silicone sealant splatter
- Paint flecks and primer overspray
- Drywall powder (gypsum residue)
- Tile cutting dust (silica particulates)
- Metal shavings from carpentry drilling
- Protective film adhesive residue (from windows, kitchen tops, appliances)
- Woodworking sawdust (deep in corners, crevices, HVAC)
- Primer / varnish fumes trapped in soft materials
Household vacuums and standard cleaners can’t effectively remove this residue. Post-construction cleaning requires commercial-grade equipment: HEPA-filtered vacuums, floor scrubbing machines, telescopic dusters, and alkaline chemicals rated for construction cleanup.
Post-construction vs post-renovation vs deep cleaning — what’s the difference?
| Service | Scope | When | Price Range |
|---|---|---|---|
| Post-Construction Cleaning | Major building works, structural A&A, new BTO handover, commercial fit-out | After contractor finishes, before furniture arrives / move-in | S$300 – S$1,850 |
| Post-Renovation Cleaning | Standard renovation (repaint, retile, carpentry install) | After renovation, before move-in | S$300 – S$1,500 |
| Deep / Spring Cleaning | Accumulated grime, grease, dust in an occupied home | Annually or before major occasion | S$220 – S$1,500 |
| Housekeeping | Routine maintenance (vacuum, mop, wipe) | Weekly / fortnightly / monthly | S$30/hour |
In practice: post-construction and post-renovation cleaning use the same chemicals and equipment. The difference is scope and scale — post-construction cleaning typically handles larger / more complex sites (whole floor, commercial space, major A&A) while post-renovation covers residential renovations.

When should you book post-construction cleaning?
Book after your contractor hands over keys and all defects are rectified, but before you move in. The ideal sequence:
- Contractor completes construction and signs handover
- You do a defect walkthrough (any rectifications first)
- Book post-construction cleaning: ideally 7-10 days before move-in
- Cleaning takes 1 day (small HDBs) to 2+ days (large landed)
- Optionally bundle: formaldehyde / VOC removal (coating) on same day
- Allow 2-3 days ventilation if you added coating
- Move furniture in
- Live happily in a construction-dust-free home
If you’ve already moved in with construction dust, it’s not too late. Post-construction cleaning still works — it just takes slightly longer because the crew works around furniture.
What’s included in post-construction cleaning?
A proper post-construction cleaning covers 10 zones:
- Floors — wall-to-wall scrubbing with commercial floor-scrubbing machine (homes over 1,500 sqft), grout line degreasing, protective film / adhesive removal
- Walls — paint flecks removed, scuff marks addressed, drywall powder vacuumed from corners
- Ceilings — cornice dust, light fixture wiping, ceiling fan cleaning (if installed)
- Built-in cabinets — interior wipe-down (cement dust loves to settle inside), hinge wipe, drawer runners cleaned
- Bathrooms — tile silicone splatter removed, grout haze cleaned, bowl / basin / tap descaling, mirror polish, chrome fixture polish
- Kitchen — hood degreasing, backsplash tile cleaning, sink + tap polishing, countertop residue removal, appliance exterior wipe
- Windows — frame and track scrubbing (where contractor’s tape may have left adhesive), interior pane cleaning, grille wipe
- Doors — frame wipe, door panel polish, handle fingerprint removal
- HVAC vents and air conditioners — fin dust removal (not internal compressor; external vents only), filter area cleaning
- Final HEPA vacuuming — captures the microscopic cement dust that regular vacuums miss
What makes post-construction cleaning different from DIY
Three things that DIY cannot replicate:
- Commercial floor scrubbing machines. Cement dust embeds in porous flooring (concrete, polished vinyl, matte tiles). A regular vacuum extracts surface dust but not embedded particles. Our commercial scrubbing machines use rotating brushes with alkaline cleaner to lift embedded residue.
- HEPA-filtered extraction. Standard household vacuums recirculate fine construction particles back into the air (and your lungs). HEPA vacuums capture 99.97% of particles down to 0.3 microns — critical for silica dust from tile cutting.
- Alkaline chemistry for cement residue. Household cleaners are pH-neutral. Cement dust needs mildly alkaline chemicals to dissolve the Portland cement bonds that make it stick to surfaces.
Attempting DIY post-construction cleaning typically means (a) spending 2-3 full weekends with inadequate results, (b) breathing silica dust (long-term lung health risk), (c) the dust being 50% re-settled within a week because your vacuum couldn’t actually remove it.
Bundling: formaldehyde / VOC removal with post-construction cleaning
New construction often introduces formaldehyde (HCHO) and other volatile organic compounds (VOCs) from carpentry adhesives, laminate flooring, paint, varnish, and new furniture. The compounds off-gas for 6-18 months and can cause throat irritation, headaches, allergic reactions. Formaldehyde is classified as a Group 1 carcinogen by IARC.
Doctor Clean’s post-construction cleaning can be bundled with photocatalyst formaldehyde removal on the same visit. Standalone formaldehyde removal is S$300 for HDB; bundled with post-construction cleaning it drops to S$88 as an add-on. The TiO2 photocatalyst coating permanently breaks down formaldehyde at the molecular level and lasts 3-5 years without reapplication.
HDB BTO handover: special considerations
BTO handovers in Singapore have unique characteristics:
- Pre-handover inspection — HDB does a quality check before keys are given. Minor issues (paint touch-ups, caulking) may still exist.
- HDB-standard finishes — vinyl flooring, homogeneous tiles, polished concrete. Each needs different cleaning methodology.
- Lift reservation — you may need to book the service lift via the HDB town council for crew access with equipment.
- Water/power — some BTOs don’t have utilities activated at handover. Our crew brings portable water tanks if needed.
- Protective films — windows, kitchen tops, bathroom fittings often arrive with protective film. Removing without scratching requires technique.
Doctor Clean has done hundreds of HDB BTO handover cleanings and knows the common quirks for each estate.
Commercial fit-out cleaning
If you’re opening a new office, retail outlet, F&B space, or clinic, post-construction cleaning is required before the space is usable. Scope differs from residential:
- Commercial-grade equipment and higher crew count (often 4-6 pax)
- After-hours scheduling to not interfere with other tenants or contractor’s final work
- Specialised cleaning for display cases, retail shelving, F&B equipment
- Grease trap and kitchen hood cleaning (for F&B)
- MOH-compliant disinfection for clinics
- Documented cleaning report for insurance / tenancy audit
Pricing: scoped quote based on floor area, equipment inventory, and scheduling window. Typically S$600 minimum for small retail (500 sqft) scaling to S$3,000+ for F&B kitchens with full degreasing.
Frequently asked questions
How much does post-construction cleaning cost in Singapore?
Residential: HDB from S$300 (2-room BTO), S$450 for HDB 4-room, S$530 for 5-room, condo from S$330 (1BR) to S$800 (4BR), landed from S$650 (terrace) to S$1,850 (semi-D/bungalow). Commercial fit-outs scoped per visit, typically from S$600. All GST-inclusive. Priced by sqft, not hours.
How long does post-construction cleaning take?
HDB 2-room BTO: 3-4 hours. HDB 4-room: 5-7 hours. Condo 2-3BR: 5-8 hours. Landed homes: 8-12 hours, often split across 2 days. Commercial fit-outs: scoped (usually overnight to not disrupt other tenants).
When should I book post-construction cleaning?
After your contractor hands over and defects are rectified, and before you move furniture in. Ideally 7-10 days before move-in day to allow buffer for any add-ons (formaldehyde removal, deep cleaning).
Can post-construction cleaning remove cement dust from built-in cabinets?
Yes. Interior cabinet wiping (upper + lower, including shelves and drawer runners) is included in Doctor Clean’s post-construction scope. Cement dust loves to settle inside new carpentry — we wipe every surface with microfibre + alkaline solution.
Will you remove paint overspray and primer flecks?
Yes, on hard surfaces. Fresh paint on glass, chrome, or ceramic can be scraped with a professional razor blade (safe technique). Dried paint on porous surfaces (concrete, grout) may need chemical removal, which we do with controlled application. We don’t repaint — that’s a different trade.
Is post-construction cleaning covered by my contractor’s handover?
Rarely. Most contractors do a basic “builder’s clean” at handover — sweeping and removing debris. True post-construction cleaning (dust extraction, grout haze removal, cabinet interior wiping, HEPA vacuuming) is separate and usually your responsibility. Check your contract carefully.
Should I bundle formaldehyde removal with post-construction cleaning?
Yes if you have significant new carpentry, laminate flooring, or built-ins — which most new HDB and condo renovations do. Formaldehyde (and other VOCs) off-gas for 6-18 months. Doing the photocatalyst coating with post-construction cleaning costs only S$88 extra for HDB (vs S$300 standalone) and gives you a permanently cleaner indoor environment.
Do you clean the aircon units at handover?
External fins and vent covers: yes. Internal compressor and coils: no — that’s an aircon specialist’s job (contractor’s responsibility if under warranty). We clean what’s visible and reachable; we don’t open the aircon units.
