Frequently Asked Questions
What's inter-flat condensation?
When the unit above runs aircon constantly, the cold floor slab transfers chill to your ceiling. Warm humid air below condenses on the cool surface, causing recurring ceiling mould. Common in older HDB stacks. Our framework diagnoses this from temperature differentials before quoting.
Will HDB cover the cost?
HDB structural defects (e.g. external wall seepage) are HDB's responsibility — we provide reports formatted for HDB submission. Internal mould from condensation, leaks or lifestyle factors is the homeowner's responsibility.
Do I need permission from HDB?
Standard mould removal and repainting within your unit doesn't require HDB approval. Major waterproofing or structural changes (e.g. drilling ceiling slab) need HDB's permission — we handle the application paperwork if needed.
What about my upstairs neighbour?
If the cause is an upstairs leak or chronic aircon condensation, the neighbour may share remediation cost. Our Neighbour Care Programme includes diplomatic liaison and joint-quote services for inter-unit mould cases.
How does HDB pricing differ from condo?
HDB units typically have smaller bathroom footprints (lower base cost), but ceiling work often needs inter-flat condensation diagnosis (adds ~$150). Condo work involves MCST coordination and external waterproofing access — different scope, similar mid-range pricing.
Bomb shelter mould — is it expensive?
Bomb shelter remediation starts at $580 and almost always includes ventilation review (the root cause is usually no airflow). We coordinate exhaust fan installation if needed.
