Mould Inspection & Testing in Brisbane and Sydney

Supporting Indoor Air Quality for Insurance,
Commercial, and Residential Properties

Do you have an air quality problem?

IECL are a leading mould testing laboratory and indoor air quality consulting firm headquartered in Brisbane. We’re known for high-quality, accessible reports and tackling complex air quality issues in homes, workplaces and factories. We service the greater Brisbane region as well as the greater Sydney region.

We’re here because we’re passionate about your indoor air quality. Working with everyone from the Australian Government and Fortune 500 companies, through to homeowners and tenants, we’re here to help you investigate and solve your indoor air quality issues.

Our other passion is comprehensive and user-friendly mould testing – with a leading Australian mould testing laboratory established here in Brisbane, we examine and interpret information about some of the most complex, most harmful mould contaminations around Australia.

The Australian Government Department of Agriculture, Water, and the Environment highlight that “indoor air pollution is [ranked] among the top five environmental risks to public health”, and CSIRO estimates that the cost of poor indoor air quality is as high as $12 billion per year in Australia alone. Don’t take your health for granted – consider having an indoor environmental professional inspect your property.

Air quality / environmental testing cost

Health is priceless, but testing can easily be expensive. That’s why IECL never book in consultants online – we will never organise for a consultant to visit your property without spending the time to understand your needs and requirements. If you’d like a phone consultation and quote, please don’t hesitate to contact us at 1300 032 004.

How do you test for air quality in your home?

The symptoms of poor indoor air quality are hard to diagnose, let alone the cause of these symptoms. Through various instrumentation, our qualified technicians are trained in detecting assorted pollutants in the air including mould, soot, particulate, gasses, radon emissions, silica dust, CO2 and volatile organic compounds, as well as other conducive elements such as humidity and temperature. Some tests require analysis in our laboratory, whilst others have onsite reading capabilities. Our dedicated staff can provide fully detailed reports and recommend solutions modeled to your specific needs.

Causes for poor indoor air quality

Poor indoor air quality is often a result of multiple related or unrelated factors. From building material degradation, to mycotoxins, chemical off-gassing and more, investigations are, by nature, highly complex and specialised. That being said, there are often common factors involved.

Water Leaks
Water leaks are one of the most common causes of poor IAQ. These can be anywhere from torrential to slow-drip leaks, but all share common factors: they encourage mould and microbial growth, they increase humidity, and, once identified, the solution is usually very clear.

Mould Growth
The common perception of mould is often vastly different to the reality. When considering health risks,  people often gravitate to the infamous “toxic black mould”, while forgetting that many other genera and species are linked to similar (or more serious) health effects. For instance, Aspergillus and Penicillium produce the mycotoxins Aflatoxins, Citrinin,  Ochratoxins, and Patulin. Some species are even colourless!

Poor Ventilation
Ventilation is sometimes forgotten, and sometimes considered the be-all-and-end-all of exposure control. This is plain silly. While ventilation is extremely useful for diluting concentrated VOCs (volatile organic compounds), for instance, increasing ventilation can sometimes have no effect, or even a net negative effect! For instance, running an HVAC system contaminated by mould will only promote mould growth in the building, and increasing ventilation after exposure is unlikely to be very beneficial. There are even horror stories in the IAQ industry of workers welding without any exhaust fans, but considering themselves safe because they ran a ceiling fan. If ventilation is not increased before exposure to the breathing zone of workers or residents, ventilation will likely not increase health outcomes.

Chemical Off-Gassing
All things break down; and many products produce harmful VOCs as they degrade. Identifying chemical off-gassing is sometimes straightforward, and sometimes very difficult. Swollen bottles, container leaks, and staining to shelving can all indicate chemical off-gassing, but some gasses vent straight into the atmosphere and are odourless and colourless. Identifying chemical off-gassing sometimes thus requires use of specialised equipment.

Other Causes
Soil compositions, sewer issues, building material degradation, bacterial issues, and other issues can all lead to poor indoor air quality. We can help you determine exactly what is causing poor indoor air quality in your premises – simply call us today to book an inspection!

Common air pollutants

Running indoor air quality tests can help confirm the presence of harmful pollutants in the air that could be affecting your health. The following pollutants can be common to households in Australia, in which we can test for:

Symptoms of poor indoor air quality

Poor indoor air quality could be the hidden cause of symptoms you may be experiencing. If you are experiencing one of these symptoms, the indoor air quality you have at your premises may be unhealthy:

  • Headaches
  • Fatigue
  • Cold/flu symptoms
  • Shortness of breath
  • Rashes or infections
  • Dizziness
  • Dryness and irritation of the eyes, nose and skin

Things you can do to improve your indoor air quality

There are a few things you can do in order to improve your indoor air quality and reduce the risk to your health.

Improving ventilation: Opening up windows and doors can help create better ventilation, encouraging air cycles, and flushing out any possible pollutants that may be present.

Cleaning you ducts: If you have air conditioning, endeavor to clean the ducts at scheduled intervals to ensure that the air being pushed through does not become contaminated by pollutants such as mould.

Being careful with use of chemicals in your house: Limit the use of chemicals in your house or choose ones that are eco-friendly. Avoid using air fresheners in your house as they can hold harmful volatile organic compounds (VOCs).

Create Air filtration: Buying/renting air purifiers which are HEPA filtered and/or carbon filtered can help to remove pollutants in the air.

Cleaning your house: Ensure your house is clean of odorous items, mould, soot marks and anything that can emit harmful pollutants. Physically removing such things can help improve your air quality.
