Weak Areas We See Most

Why a calculator helps

Most homeowners don't know whether a stain is 0.3 m² or 1.5 m² — it changes scope. The matrix gives you a defensible starting figure so the WhatsApp conversation skips the small talk.

Detection Difficulties

Take 3 photos: close-up (ruler if possible), mid-shot, and the room in context
Measure the affected area in m² — even a rough estimate is fine
Note recurrence history (first time? returns every X months?)
Note the room's ventilation (window? fan? AC running 24/7?)

Removal Challenges

Spot rate covers single substrate, single cause, single visit
Room rate covers full ceiling or full wall with multi-step protocol
Whole-property rates require a 30-min site visit ($220, credited if you proceed)
Calculator estimates are within ±15% of final quote in 90% of past cases

What Drives the Cost

Area in m² (the biggest single driver)
Number of substrates involved (paint, grout, silicone, timber)
Recurrence history (first time vs 3rd recurrence)
Tier (Essential vs Signature)
Access constraints (high ceiling, after-hours)

Frequently Asked Questions

Is the $199 spot rate really available for my property type?

Yes. $199 covers a single targeted patch (typically up to ~0.5 m²) — applied identically whether you're in a 3-room HDB, a penthouse, a landed home, or an office. The figure changes only when scope grows: more area, more substrates, more access constraints, or a higher protection tier.

Why does the calculator start at $199 instead of free?

Because real mould treatment is never free. Below $199 you're paying for cosmetic bleaching, not biological remediation. We charge $199 because that's the floor at which our protocol (HEPA pre-clean, antimicrobial pre-treatment, sealer, warranty) is sustainable.

Will the final quote match the calculator?

Within ±15% in 90% of past cases. Larger deviations happen when on-site reveals hidden scope (e.g. mould has spread inside a wardrobe or behind tiles). We always confirm the scope with you before starting work.

What's NOT included in calculator estimates?

Furniture removal beyond standard, after-hours surcharges, GST (where applicable on commercial), structural repairs (waterproofing, plumbing fixes), and aesthetic finishing beyond the treated area. All called out in the firm quote.

Why a WhatsApp photo quote instead of a paid inspection?

For 80% of cases, three photos (close-up, mid, room context) plus the affected area in m² is enough to scope honestly. We only quote a paid inspection when the cause is structurally hidden — inter-flat condensation, suspected concealed leak, or HVAC-borne contamination — and we tell you upfront before charging.
