Understanding Mould, Water Damage and Health Concerns

Water damage in homes and buildings can contribute to mould growth, particularly when affected materials remain damp. Mould may be visible, but it can also develop in less obvious areas such as behind walls, under flooring or around windows.

Some people may experience symptoms when exposed to mould, including nasal irritation, coughing, wheezing, eye irritation or skin symptoms. Reactions vary between individuals, and these symptoms can also have other causes.

People with asthma, allergies, respiratory conditions or weakened immune systems may be more sensitive to damp or mouldy environments. Anyone experiencing persistent or concerning symptoms should seek advice from an appropriate healthcare professional.

What to Do After Water Damage

If water enters a home or building:

• Dry affected areas as soon as practical.

• Identify and repair the source of the moisture.

• Remove materials that cannot be adequately cleaned or dried.

• Check for signs such as staining, bubbling paint, damp smells or visible mould.

• Seek professional advice where the damage is extensive or difficult to assess.

• Managing Mould in the Home

• The safest response will depend on the size and location of the affected area.

General steps may include:

• improving ventilation where appropriate

• reducing ongoing moisture

• cleaning small affected areas using suitable methods

• removing badly damaged materials

• arranging professional assessment for extensive or recurring mould

• following relevant building, environmental health and workplace safety guidance

• Avoid mixing cleaning products, and follow all product directions and safety warnings.

When to Seek Professional Advice

Consider contacting an appropriately qualified mould assessor, building professional or remediation service if:

• the mould covers a large area

• water damage has affected walls, ceilings or flooring

• the source of moisture is unclear

• mould continues to return

• there are concerns about structural damage

• someone in the household is experiencing ongoing symptoms

Medical assessment may also be appropriate if symptoms persist, worsen or include breathing difficulty, significant wheezing, chest tightness or other concerning signs.

There is no single supplement, detox protocol or dietary strategy proven to remove mould or mycotoxins from the body in every person. Any investigation or treatment for suspected mould-related illness should be guided by an appropriately qualified healthcare professional.
