Floors in Karachi take a beating most other cities do not — fine Arabian Sea dust through every window, monsoon mud on entry porches, construction sand from half-finished plots in DHA Phase 8 and Bahria Town. And the floor itself is rarely a single material: most Karachi homes have marble in the formal areas, ceramic or porcelain tile in the kitchen and bathrooms, terrazzo ("Karachi cement" or "chips floor") in older sections, and occasionally engineered wood in a master bedroom. Each wants a different cleaner, a different pad, a different pH, a different drying approach. On this page we explain how our team at NFS reads each surface, picks the right chemistry, and prices the work honestly.
Floor types we clean in Karachi homes and offices
Before we touch a tile we identify what we are cleaning. Marble and granite are routinely confused; ceramic and porcelain look similar but behave differently; terrazzo behaves like neither; wood is its own world. The wrong cleaner on natural stone causes damage that polishing alone may not reverse.
Marble
Marble dominates mid- and upper-segment Karachi homes — Ziarat white, Botticino, Verona, imported Carrara, locally quarried Pakistani Travertine. It is calcium carbonate, which reacts with acid. Any cleaner below pH 6 — vinegar, lemon, descaler, "tile-cleaning" supermarket sprays — etches the polished surface within seconds. We clean marble exclusively with neutral-pH cleaners (pH 7–8), typically Diversey Taski Jontec or an equivalent Ecolab product, applied with a soft white 3M 175 floor pad at low speed. For heavy soiling we step up to red, never higher. Finish: clean-water rinse, squeegee, microfibre dry pass.
Granite
Granite is silicate-based — quartz, feldspar, mica — and harder than marble. It tolerates a wider chemistry range but the polished surface still hates strong alkalinity. Mopping with caustic cleaner (pH above 11) dulls granite by attacking the mineral binders between grains. We clean granite with mildly alkaline cleaners at pH 9–10, neutral for maintenance, on a red 3M pad. The biggest thing we do for granite is reseal it — once the stone absorbs water you see darkened patches.
Ceramic and porcelain tile
Ceramic and porcelain are the workhorses of Karachi kitchens, bathrooms and balconies. Both are glassy on the surface, so chemistry options are broad — the real problem is rarely the tile, it is the grout. We clean tile in two passes: alkaline degreaser (pH 10–11) on the face with a blue 3M pad, then a separate grout-line treatment with higher-strength alkaline and a stiff nylon grout brush. Stubborn cement-haze residue from new tiling needs an acidic descaler (pH 2–3, sulphamic-acid-based), used only after confirming there is no marble or terrazzo adjacent — splash across a threshold can etch a neighbouring marble strip in seconds.
Terrazzo (Karachi cement / chips floor)
Terrazzo is what most older houses across PECHS, Bahadurabad, Nazimabad and Garden East sit on — a cementitious base with embedded marble or stone chips, ground and polished flat. The base is cement (alkaline) and the chips are usually marble (acid-sensitive), so terrazzo wants neutral chemistry, full stop. We clean it like marble. Where the floor has lost shine we recommend a separate floor polishing pass.
Engineered and solid wood
Wood floors are uncommon in Karachi but we see them in newer Phase 8 villas, some Bahria Town and Emaar units, and select commercial fit-outs. Water is the enemy — engineered wood swells at the seams under standing moisture, and a mop wrung wet rather than damp lifts the lacquer within months. We clean wood with a pH-neutral wood-floor concentrate (Bona, or Diversey wood-floor range) at high dilution, on a microfibre flat mop wrung almost dry. No scrubber, no rotary, no steam — steam delaminates engineered planks in a single cycle.
Floor-type chemistry summary
| Floor type | Cleaner pH | Pad colour | Notes |
|---|---|---|---|
| Marble | 7–8 neutral | White / red 3M | Acid etches; never use vinegar |
| Granite | 7–10 mildly alkaline | Red / blue 3M | Reseal every 18–24 months |
| Ceramic / porcelain | 10–11 alkaline | Blue 3M | Grout needs separate scrub |
| Terrazzo | 7–8 neutral | White / red 3M | Treat like marble |
| Wood | 7 neutral, high dilution | Microfibre flat mop | Never steam; never flood |
Why floor cleaning chemistry must match the surface
The most common mistake we see is a marble floor mopped for years with a strong "all-surface" supermarket cleaner. The polish is gone in the high-traffic lanes; the rest still has factory finish. The customer blames the marble. The marble is fine; the chemistry was wrong.
Acid attacks marble and terrazzo because both contain calcium carbonate, which reacts with hydrogen ions to release CO₂ and leave a roughened surface — a 30-second contact with diluted vinegar leaves a visible matte ring on polished Ziarat white. Strong alkaline attacks granite more slowly, dissolving the iron-bearing minerals that hold quartz grains together. Wood is attacked by water (mechanical swelling) and by cleaners with optical brighteners or wax. We carry five separate cleaners and change cleaner at every threshold.
Our 4-stage process — dust pick-up, wet scrub, rinse, drying control
Every job runs through the same four-stage sequence. Chemistry, pad and drying approach change with the surface; the discipline does not.
Stage 1 — Dust pick-up
Before any liquid touches the floor we do a thorough dry pick-up. Karachi floors carry a dust load much higher than the global norm — post-monsoon PM10 deposition in DHA and Clifton runs at 50–80 mg per square metre per day. Wet that dust before lifting it and you make slurry that sits in grout lines and at skirting edges. We dry-vacuum, then dust-mop with a treated microfibre flat mop.
Stage 2 — Wet scrub
On open floors we use a 17-inch single-disc rotary with the correct 3M pad. In tight spaces — bathrooms, kitchens, stairs, skirting edges — we scrub by hand. Alkaline cleaner needs three to five minutes of dwell to emulsify oily soil; rushing the dwell wastes the chemistry.
Stage 3 — Rinse and recover
On tile we use a wet-vacuum to recover dirty rinse water; leaving slurry on tile darkens the grout again within a week. On marble, granite and terrazzo we rinse with clean water and squeegee, then mop the residue with clean microfibre. On wood we do not rinse — the cleaner evaporates without it.
Stage 4 — Drying control
The stage cheap operators skip — and it determines whether the floor looks clean two days later or two months later. We dry actively with high-velocity air movers to evaporate residual moisture before it carries dissolved soil back as a film. In humid months we ask the customer to run the AC during drying; a dehumidified room dries a wet floor in under an hour where a closed unventilated room can take six.
Karachi-specific challenges
Monsoon mud at entry porches. July through September, every porch absorbs a brown slurry tracked in on shoes. On marble and terrazzo this mud is slightly alkaline (it carries cement dust from broken footpaths) and leaves a dull haze ordinary mopping does not lift. We treat it with a deep neutral scrub, clean-water rinse and full drying. For homes that take the worst of it we recommend a quarterly entry-foyer-only deep clean.
Construction dust. Phase 8, Bahria Town and DHA City are perpetual construction sites. Wet cement dust on tile forms a haze hard to remove with neutral cleaner — we treat it with mild acidic descaler on tile only, never near marble or terrazzo.
Grout darkening. Cement grout is porous and grabs oil, dust and food spatter within months. Our grout treatment is a separate step — alkaline cleaner, stiff brush, dwell, rinse. On grout darkened beyond recovery we recommend a colour-sealed grout refresh.
Marble water staining. Polished marble often shows water-shaped pale marks around dining tables. These are not stains — they are micro-etches from acidic liquids (lemon water, chai, juice, fizzy drinks). They cannot be cleaned away; they need polishing. We diagnose etching on inspection and recommend floor polishing rather than a clean that cannot deliver.
Commercial vs residential — society common areas, factory floors, retail
About 60% of our floor cleaning work is residential. The other 40% is commercial, and the equipment shifts.
Apartment lobbies, lift lobbies and stairwells take heavy foot traffic and little daily care. We run these on a monthly scheduled contract — single-disc scrub with neutral or mildly alkaline cleaner, wet-vac recovery, active drying. Most DHA and Clifton high-rises on the Creek Vista corridor and the Emaar towers run on this schedule.
Factory floors are typically epoxy-coated or polished concrete; we clean these with high-foaming alkaline degreaser and a walk-behind scrubber-dryer. Food-grade factories require food-safe chemistry (Ecolab or Diversey food-grade range) plus compliance documentation. Showroom floors — high-polish granite or porcelain — we schedule on weekday nights so the floor is dry before opening. Office work pairs naturally with full house deep cleaning for carpeted areas plus a separate pass for tile or marble in pantries and washrooms.

Frequently Asked Questions
How long does a deep floor clean take?
A 3-bedroom Karachi house — about 1,800–2,200 sq ft of finished floor — takes four to six hours from arrival to drying complete. A 5-bedroom DHA villa with mixed marble, terrazzo and wood usually runs a full eight-hour day. We leave once the floor is fully dry.
Will the marble look polished again after cleaning?
Cleaning restores the surface but does not restore polish ground away by traffic or etched by acid. If your marble has lost its mirror reflection in high-traffic lanes, the right answer is a floor polishing pass after cleaning. We diagnose this on inspection and tell you honestly whether cleaning alone will deliver.
Can you clean grout that has gone dark grey or black?
Most darkened grout responds to our alkaline grout treatment and stiff-brush scrub — we recover 80–90% of the original colour on grout neglected two to three years. Grout darkened by mildew needs a separate biocide treatment. Grout gone fully black through long-standing damp may not return; we recommend colour-sealing, a one-off treatment that resets the grout line for years.
Do you use safe chemistry around children and pets?
Yes. Our standard chemistry is low-residue and pH-controlled, and once dry leaves no surface residue. For crawling infants we use a plant-derived range — coconut-derived surfactants, citric acid, no fragrance — on request.
Do you offer maintenance contracts?
Yes — monthly and quarterly contracts for residential and commercial customers. The most common residential option is a quarterly whole-house deep clean at a 15% discount to the per-visit rate. Bundle with full house deep cleaning for a further combined discount.
