Mould, Duct & Kitchen Exhaust Services Across Perth

Perth commercial buildings and mould

Perth's commercial building stock runs from older brick and concrete offices, schools and hospitals to newer, tightly sealed buildings that depend on mechanical ventilation. Both kinds grow mould, for different reasons.

In older buildings the usual triggers are roof and gutter leaks that appear with the first winter rain, rising damp in ground-floor walls, and bathrooms, change rooms and kitchens built without enough exhaust. Water that sits in a ceiling space or behind joinery for more than a day or two can be enough for mould to start. After a burst pipe or a flooded floor, carpet, plasterboard and ceiling tiles that aren't dried quickly are a common starting point.

In newer and refurbished buildings the cause is more often inside the air conditioning: condensation on cold supply ducts and coils, drain trays that block and overflow, and fresh air rates turned down to save energy. Floors that are shut with the air conditioning off over weekends and holidays can also build up moisture, and a musty smell is often the first sign.

Mould that keeps coming back after cleaning usually has a moisture source that hasn't been fixed. That is why a Perth job starts with an inspection and, where the extent isn't obvious, mould testing with samples sent to a NATA-accredited laboratory, so the scope is right before commercial mould remediation is priced. Grease in canopies, filters and ducts is a separate fire-safety problem, covered by our commercial kitchen exhaust cleaning.
