Question 1

What's the difference between cleaning and remediation?

Accepted Answer

Cleaning treats the symptom. Remediation treats the cause. We identify and address the moisture source, contain the affected zone so spores don't travel, remove the substrate that can't be saved, and verify the outcome with post-works testing. Skip any of those steps and the mould comes back.

Question 2

Do you handle the source moisture issue?

Accepted Answer

We identify it and document it as part of the scope. For the underlying repair (a roof leak, plumbing fault, ventilation deficiency), we'll either coordinate with your existing trades or refer to a specialist - but we won't sign off remediation until the source is resolved.

Question 3

How long does remediation take?

Accepted Answer

A small contained job can be a couple of days; a large multi-zone project can run weeks. We'll give you a fixed-price scope with a realistic timeline up-front, and report progress daily. Sites with complex moisture sources or structural damage may also need a longer drying window.

Question 4

Do you provide a clearance certificate?

Accepted Answer

Yes. Every remediation closes out with a written clearance report - photo evidence, methodology, materials used, drying logs and (where required) post-works air or surface sampling results from a NATA-accredited lab. Our post-works sampling is a post-remediation evaluation by the remediator. Where your insurer, client or contract requires independent verification, we'll work alongside the hygienist you nominate.

Question 5

What does a commercial mould inspection involve?

Accepted Answer

A site walk with moisture meters and a thermal camera to map where water is getting in or condensing, a look at the ventilation and air conditioning that should be clearing it, and mould testing with surface or air samples where the extent isn't obvious. You get a written assessment that separates what needs remediation from what only needs cleaning or a ventilation fix, with a scoped price for the work. That's the same inspection we use before quoting a mine camp in the Pilbara or a hotel floor in Perth.

Question 6

Which parts of Western Australia do you cover?

Accepted Answer

We cover Perth and the metro area from our head office in Wangara. For Pilbara mould remediation, our crews travel from Perth and each job is planned ahead with the site team. In the Pilbara we cover Karratha, Dampier and Wickham, Port Hedland and South Hedland, Newman and the mine camps and villages between. We also travel to the Gascoyne and Mid West for larger commercial jobs. Remote work is scoped as a swing so the crew, containment gear and drying equipment arrive together.

Question 7

Is there an Australian standard for mould remediation?

Accepted Answer

Yes, and it's recent. AS-IICRC S520:2025, published by Standards Australia in November 2025, adopts the IICRC S520 mould remediation standard with Australian modifications. It sets out the framework we work to: assess the moisture cause, classify the contamination, contain, physically remove, then evaluate. Like other Australian Standards it's voluntary unless a contract or insurer calls it up, and increasingly they do.

The situation	The right response
Light surface mould on hard surfaces, first time	Clean
Mould that returns after cleaning	Find the source
Growth into plasterboard, carpet or insulation	Remove
Musty smell but nothing visible	Test first
