The true cost of ignoring mould in your workplace

Mould has a cost curve, and it is not linear. A stain on a ceiling tile costs almost nothing to address. The same building, a year later, can be facing a remediation quote with more zeros than anyone expected — plus everything that surrounds it.

The visible bill

Remediation means removal: plasterboard, insulation, carpet, joinery and sometimes framing. It means demolition dust, containment, disposal and reinstatement. For a single floor of a commercial building it is routinely a six-figure exercise.

The invisible bill

The bigger number is usually the one that never appears on the remediation invoice. Business interruption. Temporary space for displaced staff. Rent abatement claims from tenants. Lost enrolments in a school or childcare centre. Empty beds in aged care. Cancelled bookings in a hotel. Workers’ compensation claims. Insurance premiums that step up after the claim. Time spent by senior people managing the problem instead of the business.

Where the curve bends

The point at which mould stops being a maintenance item and becomes a capital project is usually the point at which someone decides it is structural. Regular airborne and surface treatment keeps a building on the flat part of the curve. It is a maintenance line, not a project, and it makes the project far less likely to ever happen.
