Mould removal in Perth: urgent repairs, strata and winter damp

Perth mould is a winter problem with a clock attached. The damp months are June to August, and Western Australian tenancy law gives a landlord 24 or 48 hours to organise an urgent repair. Put those together and the practical question after a leak in a rental is not how to clean the mould, but whether the cause was reported in time and who let it sit.

Who pays for mould in Perth

The rule under all of it is the same as everywhere: mould is a consequence, and the person responsible for the water is the person responsible for the mould. Western Australia’s guidance names examples on both sides of that line, which makes it worth reading before an argument rather than after.

Urgent repairs: 24 hours, 48 hours, no cap

There are two windows. An essential service gets 24 hours; other urgent repairs get 48. Consumer Protection WA, Rental home repairs lists a roof leak or possible ceiling collapse as urgent, and the damage a leak causes if it is left is exactly the kind of “exposing property to damage” the section describes.

If the landlord cannot be reached or does not act, the tenant may arrange a suitable repairer to the minimum extent necessary and be reimbursed reasonable expenses as soon as practicable. The section sets no dollar cap, unlike New South Wales ($1,000) and Victoria ($2,500). The Act’s own limits are “the minimum extent necessary” and “reasonable” expense. If the landlord does not pay, the tenant can apply to the Magistrates Court.

What WA says about the tenant’s side

Read together, the two documents draw the line at cause. A landlord cannot pass the cost of structural or ventilation mould to a tenant; a tenant who dries clothes indoors all winter without airing the room may be in breach. Report a leak in writing when you see it — it is the evidence of when the landlord knew.

Strata: repair whatever the cause, insure without flood

That last phrase is broad. The duty to repair common property applies whether the damage came from wear and tear, an inherent defect or any other cause. Mould in your lot from a common-property leak follows the water.

The statutory minimum insures against storm and tempest but excludes damage by sea, flood or erosion. A scheme can buy more, and the scheme’s policy schedule says whether it has. The strata page covers how the scheme’s policy and your contents policy meet, and the flood definition page what flood means.

Perth’s mould season is winter

Perth’s wet months are its humid mornings: July, June and August on both counts. A leak in a Perth winter dries slowly, and Consumer Protection WA’s own bulletin notes that the risk of mould increases during wet or humid weather and after major storms. The Perth page covers double brick cavity drying.

Cleaning it: HealthyWA’s method

HealthyWA says to scrub mould off hard surfaces with soapy water, up to 50 cm beyond the edge of the visible mould, and that mould sampling is not necessary to determine the health risk. It says professional help may be required where the problem is large, recurring or can’t be found (HealthyWA (WA Department of Health), Mould and dampness). The Department of Health’s 2015 guidelines treat contamination no greater than 1 m² as a simple job, and larger areas, several rooms or Category 3 water as a complex one (WA Department of Health, Guidelines for Managing Mould and Dampness Related Public Health Risks in Buildings). The mould removal guide sets HealthyWA beside the other states.

What mould removal costs in Perth

None of those figures is priced for Perth. Where a leak sits behind the mould, the drying is a separate line: two rooms over five days with one HEPA unit is $2,669 excluding GST on the published rate card.
