Air Quality Desktop Reviews

An Air Quality Desktop Review can help you understand conflicting mould, moisture, remediation and indoor air quality reports.

Environmental reports can contain technical language, different testing methods and conclusions that appear to contradict one another. This can leave you unsure which findings are relevant or what you should do next.

Air Quality Australia provides independent reviews of existing reports, laboratory results, photographs and building records. We examine the information without immediately repeating the inspection or testing.

Our Indoor Environmental Professionals consider how each assessment was conducted, looking at the timing, sampling methods, environmental conditions and supporting evidence.

You receive clear methodological commentary that explains the strengths, limitations and gaps within the available documentation.

What Is an Air Quality Desktop Review?

A Desktop Review is a professional assessment of existing environmental documentation.

Instead of beginning with another site visit, we first examine the reports and information already available. This can provide valuable clarity before you invest in further inspection, testing or remediation.

Documents reviewed may include:

  • Mould and indoor air quality reports
  • Water-damage assessments
  • Post-Remediation Verification reports
  • Laboratory certificates and analytical results
  • Air, surface and dust sampling results
  • Moisture maps and psychrometric readings
  • Remediation scopes of work
  • Building plans and repair records
  • Photographs and thermal images
  • Insurance, contractor or occupant correspondence
  • Maintenance and water-intrusion histories

We bring this information together to create a clearer picture of the building and the methods used to assess it.

When Can a Desktop Review Help You?

A Desktop Review can be useful when you’ve received different opinions about the same property.

One assessor may report acceptable ambient air results. Another may later identify settled spores inside a wall cavity. These results don’t necessarily measure the same conditions or answer the same question — and that’s where we can help.

A review may assist when:

  • Two environmental reports reach conflicting conclusions
  • Testing occurred at different times or in different locations
  • You’re unsure whether sampling methods can be compared
  • A remediation contractor’s work has been questioned
  • A report has been described as a Post-Remediation Verification
  • An insurer or property manager needs independent technical commentary
  • You want a second opinion before approving further work
  • Important moisture, humidity or building data appears to be missing
  • A proposed remediation scope seems excessive or unclear
  • You need to decide whether another site assessment is justified

The review can help you avoid unnecessary testing and make your next decision with greater confidence.

Independent Comparison of Environmental Reports

Environmental reports shouldn’t be compared solely by looking at whether mould was found. Testing methods collect different types of information.

An air sample provides a short snapshot of particles suspended during the sampling period. A tape lift examines material found on one selected surface. A dust sample may represent particles that accumulated over a much longer period. Sampling an occupied room is also different from sampling inside a sealed wall cavity.

Our team examines whether the reports used compatible methods, and whether the conclusions reflect those differences. We may consider:

  • The dates and time between assessments
  • Whether the same rooms or materials were tested
  • Ambient, surface and interstitial sampling differences
  • The amount of air or material sampled
  • Indoor and outdoor comparison samples
  • Laboratory comments and reported limitations
  • Changes in occupancy, cleaning or building use
  • Repairs or water events occurring between assessments
  • How inspection activities may have affected the samples
  • Whether the conclusions extend beyond what the results demonstrate

This gives you a balanced analysis of what can and can’t reasonably be concluded.

Reviewing Post-Remediation Assessments

The timing of a Post-Remediation Verification, or PRV, is important.

A PRV is intended to assess conditions after remediation and before containment systems are removed or normal occupation resumes. An inspection completed many months later may describe the building’s current condition, but it may not represent conditions immediately following the original remediation.

During a Desktop Review, we examine whether the report’s title, timing and assessment criteria match the work that was actually performed. We may review:

  • When the remediation was completed
  • When verification or later testing occurred
  • Whether the building had returned to normal use
  • Whether containment and negative pressure were still operating
  • Whether the moisture source had been corrected
  • Whether materials were dry at the time of assessment
  • What may have changed between inspections
  • Whether later findings can reasonably be attributed to the earlier event

This helps distinguish a genuine PRV from an assessment of current environmental conditions.



Moisture, Humidity and Building Conditions

Mould findings can’t be interpreted properly without considering moisture.

A building’s conditions can change significantly over weeks or months. Leaks, ventilation problems, occupant activities and seasonal weather may all influence indoor humidity and moisture movement. Cooking, showering, clothes drying and unvented appliances can add moisture to indoor air, which may travel through the property and enter cooler wall or ceiling cavities.

Our review considers whether the reports adequately assessed:

  • Temperature and relative humidity
  • Vapour pressure and dew-point conditions
  • Moisture levels in building materials
  • Laundry, bathroom and kitchen ventilation
  • HVAC operation and airflow
  • Known leaks or water-intrusion events
  • Seasonal and local weather conditions
  • Occupancy and normal building use
  • Active moisture compared with historical staining

When this information is missing, we clearly identify the limitation. We don’t assume that conditions measured on one day represent the previous months.

Identifying Sampling and Methodological Limitations

Every sampling method has limitations.

A surface sample can’t establish the age of every particle collected. A short air sample can’t describe all conditions over an extended period. Material found inside a wall cavity doesn’t automatically show that the occupied area has the same conditions.

Inspection methods may also influence the environment being tested. Cutting plasterboard, opening a cavity or disturbing insulation can release mineral dust and settled particles. We examine whether these factors were acknowledged and managed.

Our review doesn’t dismiss results simply because limitations exist. It explains how much weight the findings should reasonably carry, giving you a more accurate understanding of the evidence.

Who Can Request a Desktop Review?

Our independent Desktop Reviews can assist:

  • Homeowners and property investors
  • Builders and remediation contractors
  • Insurers and loss adjusters
  • Property and strata managers
  • Commercial building owners
  • Tenants and occupants
  • Legal representatives and technical consultants
  • Government and community organisations

You don’t need to understand the technical terminology before contacting us. Send us the reports and explain your concerns, and we’ll review the available documents and advise whether a Desktop Review is appropriate.

What Will You Receive?

You receive a written review prepared around the questions you need answered.

Depending on the available information, the review may include:

  • A summary of the relevant building history
  • A comparison of the reports and sampling methods
  • Identification of inconsistent findings or terminology
  • Discussion of chronological and environmental gaps
  • Commentary on moisture and psychrometric information
  • Explanation of laboratory findings and limitations
  • Identification of unsupported or overstated conclusions
  • Questions requiring further investigation
  • Practical recommendations for the next step

A Desktop Review is based on the documentation supplied. It does not replace a site inspection when current physical conditions need to be assessed.

The review provides independent environmental commentary. It is not legal advice and does not determine contractual liability.

Clear Answers Before You Spend More

You may not need to begin with another full inspection or broad testing program.

An Air Quality Desktop Review can show whether the existing documents already contain useful answers. It can also identify the specific gaps that require further investigation, giving you a more focused and cost-effective way forward.

If a site inspection or additional sampling is required, we explain what should be investigated and why.
