Weak Areas We See Most

Universal: wall-ceiling cornice

Top of walls is the universal first-failure zone — cold surface meets warm rising vapour. True across every property type.

Universal: AC ledge / aircon shelf

Drain-line condensation behind the indoor unit. Often misdiagnosed as wall mould.

HDB-specific: bedroom ceiling under upstairs wet area

Inter-flat condensation. See HDB pricing.

Condo-specific: balcony soffit + planter

Direct rain + waterproofing failure. See condo pricing.

Landed-specific: basement, attic, exterior masonry

Capillary moisture, roof condensation, wind-driven rain. See landed pricing.

Commercial-specific: HVAC plenums & chiller surrounds

Centralised systems condense out of sight. See commercial pricing.

Detection Difficulties

Recurring mould after bleach = structural cause; budget for diagnostic, not retreat
Patchy 3D growth = mould; flat black streaks = algae (cheaper)
Smell-only with no visible mould = HVAC, sub-floor, or hidden cavity — needs site visit
One-room-only mould = orient that wall; usually NW or SE rain-driven
Mould on belongings (shoes, bags) = ambient RH issue, not surface mould — dehumidifier strategy needed

Removal Challenges

What Drives the Cost

Area in m² (linear scaling)
Substrate (cement render = cheapest; lime, timber, wallpaper = more prep)
Access (ladder vs scaffold vs MEWP)
Tier (Essential vs Signature)
Continuity needs (in-hours vs after-hours vs weekend block — commercial)
Documentation depth (insurance vs MCST vs MOH vs nil)

Frequently Asked Questions

Is the $199 full-surface promo really available for my property type?

Yes. During this limited-time promo, the first full ceiling or wall surface (Essential tier) is $199 — normally $299. Same protocol whether you're in a 3-room HDB, a penthouse, a landed home, or an office: HEPA pre-clean, antimicrobial pre-treatment, Nippon anti-mould paint, protective sealer, and a 6-month warranty. Additional surfaces in the same room are +$100 each (unchanged).

What's the difference between Essential and Signature tiers?

Essential = antimicrobial + protective sealer, $199 for the first full ceiling/wall surface (limited-time promo, normally $299) and +$100 for each additional surface in the same room (6-month warranty). Signature = same prep + engineered anti-mould paint system (Zinsser, Gush or Breathe), $400 for the first full surface and +$150 each additional (24-month warranty). Signature earns its premium in heavy-use rooms, recurrence-prone properties, and ambient RH >70% locations.

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.

Is there a warranty?

Yes. Spot patch ($199) carries a 90-day no-recurrence warranty on the patched area; Essential tier carries a 6-month warranty on the treated surface; Signature tier (with engineered anti-mould paint) carries a 24-month warranty when applied to a properly prepared substrate. Warranty excludes seepage, structural defects, diagnostic scans and new water ingress events. See full terms at /warranty.
