Mould Remediation Services in Perth

Professional remediation is recommended when mould covers more than 1 square metre, is inside wall cavities or HVAC systems, or when occupants experience respiratory symptoms. Visible mould often indicates a larger hidden problem. A qualified mould assessor conducts air quality testing to identify species and contamination levels before remediation begins.

Standard residential mould remediation takes 3 to 5 days: day 1 for assessment and containment setup, days 2-3 for removal and treatment, day 4 for HEPA air scrubbing, and day 5 for clearance testing. Larger or multi-room jobs may take longer. The moisture source must be fixed before remediation to prevent recurrence.

Black mould (Stachybotrys chartarum) produces mycotoxins that can cause respiratory issues, allergic reactions, and other health effects. However, not all dark-coloured mould is Stachybotrys. Professional air quality testing identifies the species present and contamination level. Any mould affecting more than 1 square metre warrants professional assessment regardless of colour.

Insurance typically covers mould remediation when it results from a covered event (burst pipe, storm damage, flood). Pre-existing or maintenance-related mould is generally excluded. We bill you directly so remediation begins immediately. Our contractors provide full documentation including air quality reports and moisture source identification to support your claim.

Lasting mould prevention requires fixing the moisture source (leak repair, ventilation improvement, waterproofing), maintaining indoor humidity below 60%, ensuring adequate ventilation in wet areas, and applying antimicrobial coatings to treated surfaces. Our contractors identify and document the moisture source as part of every remediation job.

All contractors hold IICRC Applied Microbial Remediation (AMRT) certification and follow IICRC S520 standard for professional mould remediation. They carry minimum $20 million public liability insurance and use containment, HEPA filtration, and antimicrobial treatments that meet Australian standards.
