Floor deep cleaning in Singapore usually costs about $0.35–$0.70 per square foot — roughly $250–$500 for an HDB flat — while marble polishing runs $2.50–$8 per square foot, depending on how much grinding the stone needs. Dull marble, black grout and scratched parquet can nearly always be restored, without hacking up the floor and re-laying it.

What floor deep cleaning actually is (and how it differs from mopping)
A mop pushes dirt around in dirty water. A weekly cleaner keeps a floor tidy. Floor deep cleaning is a machine job — a rotary scrubber with the right pads or brushes, an alkaline or acidic solution matched to your surface, agitation along the grout lines, then extraction and drying. It pulls out the embedded grime and mineral film a mop simply can’t reach.
If your floors only need routine upkeep, that’s a job for a general weekly home cleaning plan. You book a deep clean when the floor already looks tired, hazy or stained — or once or twice a year as a reset.
How much does floor deep cleaning cost in Singapore?
Most companies price per square foot or to a per-job minimum, and the floor material matters more than the postcode. A homogeneous-tile HDB floor is quick. A large marble condo living room is not.
| Service | Typical Singapore price band | What it involves |
|---|---|---|
| Floor deep clean (tile, vinyl, homogeneous) | ~$0.35–$0.70/sqft, ~$250–$500 per HDB flat | Machine scrub, grout agitation, degrease, rinse, dry |
| Marble/terrazzo crystallisation (maintenance polish) | ~$1.50–$3.50/sqft | Buffing compound + pads to restore shine, no grinding |
| Marble grinding + honing + polishing (full restoration) | ~$3–$8/sqft | Diamond grinding to level, honing through grits, polish, seal |
| Parquet screen & recoat (buff + recoat) | ~$2–$4/sqft | Light abrasion + fresh coat, no deep sanding |
| Parquet full sanding + re-varnish | ~$3.50–$6.50/sqft | Sand to bare timber, stain, multiple varnish coats |
| Grout deep clean / recolour | Priced per job, often $150+ minimum | Alkaline/steam clean, optional epoxy recolour + reseal |
HDB vs condo rarely changes the rate itself — it changes the total, because a condo has more floor and usually more marble. What pushes your number up: floor type (marble and timber cost more than tile), how bad the condition is, whether sealing is included, and access or furniture in the way. Always get a quote for your actual floor rather than trusting a headline price.
Marble polishing: grinding, honing, crystallisation and sealing
This is where a “cheap” quote and an “expensive” quote are often describing two completely different jobs.
- Crystallisation / maintenance polishing — a buffing compound reacts with the marble to bring back gloss. Fast and affordable, but it only works on marble that’s still sound and lightly dulled.
- Diamond grinding and honing — for etched, scratched or uneven (lippage) marble, the crew grinds the stone flat with progressively finer diamond pads, removing the damaged top layer to expose fresh stone underneath.
- Sealing — a penetrating sealer soaks in to slow future staining. It won’t make marble waterproof, but it buys you time to wipe a spill before it etches.
The gap between a buff and a full grind is the gap between a few hundred dollars and a few thousand. That’s exactly why the cheap quote and the proper quote look nothing alike — check which one you’re actually being sold.
Is marble polishing worth it, or should you replace the floor?
In almost every case we see, restoration beats replacement on both cost and disruption. Hacking out marble and re-laying means demolition, new stone, weeks of dust and a five-figure bill. A full grind-and-polish restores the *same* floor for a fraction of that, in a day or two, with no hacking. Replacement only makes sense when tiles are cracked, lifting or debonded from the screed — a structural problem no amount of polishing will fix.
Why grout turns black or yellow — and whether it comes back
Humidity is the culprit. Grout is porous, so in a warm, damp flat it soaks up moisture and grows mould and mildew in the lines — the black you see is biological, not just dirt. Yellowing is usually soap scum and mineral buildup. Deep cleaning with the right alkaline treatment and agitation lifts most of it. But grout that’s already degraded or permanently stained is better recoloured and resealed — an epoxy recolour gives you a clean, even line that resists mould far longer than raw grout. Skip the sealing and the black simply comes back in a humid bathroom or kitchen.
Can parquet and timber be restored without full sanding?
Often, yes. If your parquet is dull, lightly scratched and greyed from surface wear — but the timber underneath is sound — a screen-and-recoat (buff off the tired top layer, lay a fresh coat) brings back the sheen without sanding to bare wood. Full sanding and re-varnishing is only necessary when there’s deep gouging, water-blackened boards, or the finish has worn through completely. The classic Singapore mistake here is a soaking-wet mop: water seeps between the boards, they swell and lift, and what could have been a light recoat becomes a replacement job.
Do you need special floor cleaning after renovation?
Yes, and it isn’t optional. New handovers and reno jobs leave a cement or grout haze, fine silica dust, paint splatter and adhesive baked onto the floor. Ordinary mopping just smears it around. Getting it off needs an acidic haze remover (on tile), careful mechanical cleaning, and detailing along edges and grout lines. It’s why our post-renovation cleaning and move-in/move-out cleaning jobs treat the floor as its own stage, not a quick wipe — a BTO or freshly renovated unit never looks right until that film is off. If you only need the floor sorted, our floor deep cleaning service covers it on its own.
How long it takes and how to prepare your home
A floor deep clean for a typical HDB flat runs about half a day. A full marble grind-and-polish in a larger condo can take one to two days, because each grit pass and the final seal need time to set. To keep things on schedule:
- Move small furniture and clear the skirting where you can — the crew can shift the heavy pieces.
- Lift rugs and mats. If you want them done too, ask about carpet and rug cleaning on the same visit.
- Plan to stay off the floor while it’s wet or curing. This is the step people forget, and footprints or paw prints on fresh polish mean re-doing that patch.
DIY floor scrubber: when it’s fine, when it wrecks the floor
Renting a scrubber for tile or vinyl is fine for maintenance. DIY goes wrong on stone and timber. The rescue jobs we get called to almost always involve the wrong pad on marble (swirl marks and burn spots), an aggressive machine gouging parquet, or an acidic cleaner etching a good marble slab into a dull haze. At that point the customer pays for a full grind to undo the damage — more than the job would have cost in the first place. If the surface is soft, expensive or already damaged, get a professional in.
Red flags when hiring a floor polishing company in Singapore
- A quote with no site visit and no question about your floor type — marble, terrazzo and tile need completely different treatments.
- No mention of sealing on marble or grout — the shine won’t last.
- Suspiciously cheap “polishing” that’s really a quick buff over damage that needs grinding.
- No before-and-after photos — proper crews document the work.
- Vague “we clean everything” freelancers with no insurance. A gouged marble floor is a five-figure mistake, so you want a trained, insured crew standing behind the result — which is how we run ours: employed staff, not gig labour.
How often should you deep clean or polish?
For most Singapore homes: deep clean the floors once or twice a year, and re-polish marble every one to three years, depending on traffic and day-to-day care. High-use entryways and kitchens wear faster; a lightly used bedroom can go much longer.
Frequently Asked Questions
Is marble polishing cheaper than replacing the floor in Singapore? Almost always. Polishing and diamond grinding restore your existing marble for a fraction of the cost of hacking out and re-laying — usually in a day or two, with no demolition dust. Replacement only makes sense if the stone is cracked, lifting or debonded from the screed.
How do I get rid of black, mouldy grout for good? Deep cleaning with an alkaline treatment lifts most of the mould, but in humid Singapore it returns if the grout stays porous. The lasting fix is to recolour and reseal the grout lines so moisture can’t soak back in and feed mildew.
Can dull, scratched parquet be restored without full sanding? Often, yes. If the timber underneath is sound, a screen-and-recoat buffs off the worn top layer and adds a fresh finish without sanding to bare wood. Full sanding is only needed for deep gouges, water-blackened boards, or completely worn-through varnish.
How long does marble polishing take for a condo? Expect one to two days for a larger unit. Diamond grinding runs through several grit passes and the final seal needs curing time, so a proper restoration can’t be rushed into a couple of hours.
Do I really need special floor cleaning after a renovation? Yes. Renovations leave cement haze, fine silica dust, paint and adhesive that ordinary mopping only smears around. Post-reno floors need an acidic haze remover and mechanical cleaning before they’ll look right — it’s a dedicated stage, not a quick wipe.
How much does floor deep cleaning cost for an HDB flat? As a market band, roughly $250–$500 for a typical flat, or about $0.35–$0.70 per square foot, depending on floor type and condition. Marble and timber cost more than tile — request a quote for an exact figure.
