Mould Assessments

Mould assessments are critical for identifying and addressing hidden health hazards within homes. While mould is often invisible and odourless, its effects can have devastating consequences on the health of occupants. Many cases of water-damaged buildings reveal pathogenic mould levels that can exacerbate or even cause chronic health conditions. A thorough mould assessment is essential to uncover these hidden dangers and provide actionable solutions.

Why Mould Is a Serious Concern

Mould exposure has long been associated with respiratory issues such as asthma, bronchitis, cold and flu-like symptoms, and hay fever. However, recent research indicates that the health effects of mould are more complex. It is not just the fungi themselves but the chemical stew of bacteria, fungi, and their by-products that pose significant risks. These microbial toxins can trigger inflammatory responses, especially in individuals with a genetic predisposition that prevents them from producing antibodies to fungi.

In susceptible individuals, exposure to mould and water-damaged environments can lead to:

  • Fatigue and persistent headaches

  • Brain fog, including memory loss and mood swings

  • Joint pain and sleep disturbances

  • Difficulty regulating body temperature

  • Excessive thirst, urination, and heightened sensitivity to electric shocks

These symptoms can mimic or be misdiagnosed as chronic fatigue syndrome, fibromyalgia, depression or other conditions, often leaving sufferers without appropriate support.

Modern Building Practices and Mould

Mould has existed for millions of years, but its impact on human health has intensified due to modern construction and building materials. Key contributors include:

  1. Energy-Efficient, Airtight Homes: While designed to conserve energy, these homes often have poor ventilation and are more susceptible to condensation and moisture build-up.

  2. Short-Lived Waterproof Membranes: Transitioning from durable sheet-based membranes to liquid coatings with an 8–10 year lifespan has increased water damage risks.

  3. Flexible Braided Hoses: Commonly replacing copper pipes, these hoses are prone to failure, accounting for 22% of water damage insurance claims in Australia.

  4. Vulnerable Building Materials: Modern materials such as paper-faced gypsum board and man-made timbers like MDF and chipboard are highly susceptible to fungal growth compared to older, more durable materials.

How Mould Affects Homes and Occupants

Mould thrives in damp, poorly ventilated environments, breaking down materials and releasing spores and mycotoxins into the air. Even new homes are not immune due to design flaws, cheap materials, and inadequate waterproofing. Mould can infiltrate unseen areas like wall cavities, subfloors, and roof spaces, making professional assessments crucial for detection.

The Role of Mould Assessments

Professional mould assessments are essential for:

  • Uncovering Hidden Risks: Identifying mould infestations in areas that may not be visible or obvious.

  • Assessing Health Impacts: Measuring air quality and identifying pathogenic fungi that could affect occupants' wellbeing.

  • Recommending Solutions: Offering targeted remediation plans to reduce or eliminate mould and its harmful effects.

A mould assessment can assist in protecting the health of the home's occupants while also preserving the structural integrity of the building. By addressing issues early, homeowners can prevent long-term health and financial costs, creating safer and healthier living environments.

A Wave Building Biology Mould Assessment includes the following:

  • A free 20 minute initial phone consultation to identify client needs

  • Client pays $200 to receive a detailed questionnaire and for a follow-up video conference (approximately 40 minutes)

  • Client completes questionnaire (this may take 1-2 hours)

  • Video conference to discuss questionnaire and to determine best course of action (approximately 40 minutes). Face to face meeting in Woolgoolga optional

  • Client pays $1320 for site inspection, four lab samples, detailed report with customised recommendations and follow-up videoconference

  • Building Biologist site visit. Assessment takes around three hours. Lab samples taken and sent to laboratory. Depending on extent of water ingress issues, additional lab results may be required (samples will be taken during site visit), at a cost of $110 each

  • Report with customised recommendations sent to client within two weeks of site visit

  • Follow-up video conference with client to discuss results, recommendations and remediation (approximately 40 minutes).
