Condo & Strata Mould Pricing Singapore

Quick Answer

Condo mould removal costs $199 for the first full ceiling or wall surface (Essential promo, normally $299), +$100 per additional surface, or $400 per surface for Signature Care. Where the source is an upstairs unit or common property, we document the cause so your MCST can decide cost responsibility under strata rules.

Weak Areas We See Most

Ceiling below upstairs bathroom or kitchen

Identical mechanism to HDB inter-flat — but in condos the responsibility is governed by your BMSMA strata schedule. Our diagnostic separates 'condensation' (your problem) from 'leak from upstairs' (potentially the upstairs unit / MCST's problem).

Balcony soffit & planter wall

Balconies face direct rain plus afternoon dew. Planter boxes are notorious — the waterproofing membrane underneath fails silently, mould blooms on the wall behind the planter rather than at the source.

AC ledge / aircon shelf interior

Drain pan slope errors and condensate trickle behind the unit. Often missed because the visible wall is fine — mould is on the back face, only smelt.

Service yard riser cupboard

Concealed pipe risers run condensation in chilled water lines. The cupboard becomes a permanent 70%+ RH micro-climate. Stored cleaning supplies and shoe storage suffer first.

Walk-in wardrobe against shaft wall

Wardrobe shares wall with cold lift shaft or M&E riser. Hidden side of wardrobe back panel develops mould; clothes/leather are usually the early-warning indicator.

Detection Difficulties

Brown ceiling halo with no upstairs renovation history = condensation, not leak — diagnosed not patched
Mould only in one bay of a long balcony = drainage slope error, not waterproofing failure
Sweet musty smell from AC = drain-line biofilm (not actually wall mould)
Mould on bedroom wall directly behind wardrobe = condensation, requires ventilation strategy not just paint
Recurrence within 6 months on a 'fixed' patch = previous job skipped antimicrobial pre-treatment step

Removal Challenges

MCST-affecting work needs documented containment — we issue a containment plan + before/after photos as standard for any ceiling job
Lift access windows: most MCSTs require booking; we coordinate but it adds 1–2 day lead time
Penthouse soffits often need MEWP (mobile elevated work platform) instead of scaffold — adds $400–$800 depending on duration
Balcony work is weather-gated: we won't paint in PSI>100 or within 6 hours of forecast rain — protects the warranty
Common-property reinstatement (corridor, lift lobby) must be like-for-like; we use micro-fibre dust capture to avoid claims

What Drives the Cost

Strata complexity: simple unit-only fix vs MCST-coordinated job (+$150–$400 for documentation)
Access: lift booking, working hours restriction, security pass — adds time not material
Balcony orientation: NW/SE faces get 2× the rain load — Signature Care strongly recommended
Floor level: high-floor units have higher wind-driven rain exposure; low-floor have higher ground-humidity load
Existing finish: timber/wallpaper substrates need careful prep that paint-on-paint doesn't

Who actually pays — strata in plain English

Singapore's BMSMA assigns mould responsibility based on cause and location, not visibility. A useful rule of thumb:

Inside your unit, your-cause (poor ventilation, unit AC drain) → you pay
Inside your unit, neighbour-cause (upstairs leak, party-wall plumbing) → upstairs unit's responsibility, often via their insurer
Inside your unit, common-property cause (façade waterproofing, common riser leak) → MCST responsibility
On common property (corridor, lift lobby) → MCST

What we document for your MCST claim

Cause-of-water report with photos and moisture-meter readings
Cross-section sketch showing water path
Containment & remediation log (for insurer)
Before/after photo set with timestamps
Recommended preventive scope for the upstream cause (so the same patch doesn't recur)

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: full surface preparation, complete mould removal, Nippon anti-mould paint, protective sealer, and a 6-month warranty. Additional surfaces in the same room are +$100 each (unchanged).

The unit above me is causing my ceiling mould — what do I do?

Get our diagnostic report (the Essential full-ceiling tier ($199/surface limited-time promo, normally $299) includes it). Submit to your MCST with a written request for action under BMSMA. If MCST stalls, your insurer can subrogate against the upstream unit. We've never had a documented case rejected for evidence quality.

Why is condo sometimes more expensive than HDB?

Three reasons: (1) MCST documentation overhead, (2) access constraints (lift bookings, working hours), (3) higher-spec finishes (timber, marble) requiring more careful prep. The biology of the job is identical — the logistics cost more.

Can you work after-hours so my domestic helper isn't disrupted?

Yes — most condos allow 9am–6pm Mon–Sat for noisy work, quieter prep can run earlier/later. We'll quote any after-hours surcharge upfront ($60–$120/hr depending on team size).

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 Care (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.
