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 tier 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: 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).

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 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.
