Mould Remediation Perth: Find the Source, Then Fix It
Mould removal in Perth is a moisture job first and a cleaning job second. Whether it’s a ceiling after winter rain or a downstairs room where water crept in, mould only grows where something stayed damp. Remediation tracks down that source, contains the affected area, removes what can’t be saved, treats the surfaces that can, and dries the structure.
Not every patch needs a crew. A little growth on a shower ceiling is often a fan and a wipe. When it spreads, returns, follows a leak or affects someone with a breathing condition, an inspection is the sensible next step.

“We had a pipe burst in our ceiling, water seeped into our walls and our unit was at a very high risk for mould :( Guosheng worked tirelessly to ensure the drying process went as smooth as possible, even working until the evening on a Friday to ensure our walls would be dry and safe over the weekend! An extremely proficient and productive company that thrives on providing excellent service and quality work. Thank you so much for all of your help! <3”
“Guosheng from Elite Restoration did an amazing job dealing with the water damage to my unit, due to a burst pipe. Nothing was too hard and Guosheng had multiple tricks up his sleeve to ensure maximum drying capacity. The communication throughout the whole process was excellent, which made this very stressful situation for me a lot easier to handle. Thanks so much Guosheng.☺️”
Mould remediation is never a simple clean. Under the
IICRC S520 Standard for Professional Mould Remediation,
treating mould without a proper inspection risks missing the underlying
moisture source and leads to recurrence. Every mould job starts with a
professional inspection by S520-certified technicians, so containment,
controls and the remediation scope are set correctly from day one.
Inspection from $350 inc. GST. Remediation is scoped and
quoted separately, only after the inspection.
Find the cause — identify the moisture source so remediation actually holds.
Set containment — protect unaffected areas during the work.
Clear scope & documentation — written report you can give insurers or strata managers.
Want to know exactly what you’ll receive? Download a real example of the
written report our S520-certified technicians produce after a mould
inspection — findings, moisture readings, photos and the recommended
remediation scope.
Here’s the order of work, carried out in line with IICRC S520:
An inspection of the affected rooms to find where the moisture is getting in, with sample testing through NATA-accredited laboratory partners if it’s needed.
Containment of the work area so spores don’t spread to clean rooms.
Removal of damaged material, such as water-soaked lining or carpet underlay.
An antimicrobial treatment on what stays, then drying of the structure.
Monitoring on alternate days until it’s dry, then a completion report within 24 to 48 hours.
A recent Perth job shows how it starts. In July 2026, mould was identified due to water ingress in the downstairs living area of a property in Perth, requiring urgent make safe measures. The same month, water ingress caused wet conditions in a family room in Embleton, requiring drying, which is the kind of job that heads off mould before it starts.

What you do while we work
Most people stay at home through a remediation job. The contained area is off limits until it’s dry, and the rest of the house carries on as usual. Monitoring on alternate days tells us when the structure is dry, and the completion report confirms the rooms are ready to use again. Before any of that, you’ll have an initial report and a scope or quote within 24 hours of the inspection.
The standard we hold the work to
Each job is measured against IICRC S520. We’re an IICRC Certified Firm, and our technicians hold certifications that include applied microbial remediation and applied structural drying. That’s what you’re getting: work that follows a published standard, with live onsite reporting and a scope you can check before anything is removed. If there’s an insurance claim, we liaise with your insurer from first call to final sign-off.
