Words: Jeff Cross

Mould is more than just an unsightly issue in homes; it’s also a hidden danger that can significantly affect the health and wellbeing of anyone exposed to it.

In a recent episode of Unscripted, an IICRC video program, ISSA media director Jeff Cross investigated the critical topic of mould contamination in homes. The episode highlights a harrowing experience faced by a Florida family (see sidebar) and provides expert advice from industry professionals on detecting, preventing and addressing mould in homes.

Understanding the health risks of mould

Mould is common in many homes, particularly in areas with high humidity, like Darwin and Cairns. However, not all moulds are equal. While some moulds can be relatively harmless, others, like Aspergillus, can pose severe health risks, especially to individuals with compromised immune systems.

Mould exposure can lead to various health problems, including respiratory issues, allergic reactions and more severe conditions, such as infections that can spread throughout the body. As mentioned in the sidebar article, Nicholas Morse’s immune deficiency made him particularly vulnerable to the dangers of mould, leading to a devastating outcome.

Mould detection and prevention

Cleanfax invited comments from mould remediation specialists Mark Cornelius and Holly Burns, both IICRC-approved instructors. They provided information about where mould is commonly found in homes and how to address it effectively.

Cornelius said mould is a symptom, while moisture is the root cause. To effectively address a mould problem, finding and eliminating the moisture source is essential. Whether it’s a leaky pipe, poor ventilation or condensation, stopping water intrusion is crucial in preventing mould from returning.

Mould can be found in various areas of a home, particularly in places with high moisture levels, such as bathrooms, basements and around windows. While mould in a shower or a basement corner may seem minor, it’s essential to address it promptly to prevent it from spreading.

One key indicator of mould presence is a musty odour. “If you can smell mould, it’s likely that there’s more of it hidden within your home, even if it’s not immediately visible,” Cornelius explained. In such cases, it’s crucial to investigate further and take appropriate action.

Proper ventilation is critical in preventing mould growth. Burns emphasised the importance of running exhaust fans during and after showers to remove excess moisture from bathrooms. For homes without vent fans, she suggests using oscillating fans or opening windows, when possible, to reduce humidity levels.

When to call a professional

While minor mould issues can sometimes be managed with regular cleaning, professionals should handle more extensive contaminations of mould that cause health problems. According to Burns, professional testing, including air sampling and surface swabbing, is crucial in determining the severity of a mould problem. This testing helps identify the type of mould present and the necessary steps for remediation.

The cost of mould remediation

One of the most significant concerns for homeowners facing mould contamination is the remediation cost. Unfortunately, as Cornelius explained, many mould issues result from neglect, which is not typically covered by insurance policies. This often leaves homeowners responsible for paying for remediation out of pocket, which can range from a few hundred to several thousand dollars, depending on the severity of the problem.

Burns added that while cost is a consideration, the health and safety of the family should be the top priority. If mould is causing health issues, it’s critical to address it promptly, regardless of the cost.

Government regulations and industry standards

The discussion also touched on the role of government regulations in mould remediation. While some states require mould assessors and remediators to be licensed, the industry remains relatively unregulated in many areas. Both Cornelius and Burns agree that more regulations could help protect consumers by ensuring that only qualified professionals handle mould remediation.

Some states are adopting IICRC standards as the basis for mould remediation regulations. As more states recognise the importance of protecting public health through proper mould remediation practices, this trend is expected to continue and grow.

Protecting homes from mould contamination is a grave issue that can devastate the health of your clients. The cleaning and restoration industry can prevent this from happening with the help of the IICRC.
