Mould and Asthma: What Tenants Should Know

Understanding the Link Between Mould and Asthma Mould growth in rental properties is more than just an unsightly nuisance; it is a significant environmental health concern, particularly for those living with asthma. In the humid climates of the Hunter Valley, Central Coast, and Lake Macquarie, spores can spread rapidly, triggering severe respiratory reactions in susceptible individuals. If you are a tenant and find yourself struggling to breathe or experiencing increased asthma symptoms at home, understanding the connection is the first step toward reclaiming your health and your living space. ## How Mould Impacts Respiratory Health When mould spores are inhaled, they can trigger allergic reactions, irritation of the airways, and, in severe cases, acute asthma attacks. Mould produces mycotoxins and allergens that inflame the mucous membranes in the nose and lungs. For an asthmatic, this is particularly dangerous because their airways are already prone to narrowing and inflammation. Living in a home with persistent moisture issues—such as leaking pipes, rising damp, or poor ventilation—means you are in a constant state of exposure, which can exacerbate chronic conditions and lead to long-term health complications if left unaddressed. ## Steps Tenants Should Take If Mould Appears If you discover mould in your rental property, it is essential to act methodically to protect both your health and your tenancy rights. Follow this professional guide: 1. Document Everything: Take clear, date-stamped photographs of the mould growth, including the affected area and any sources of moisture like roof leaks or damp walls. 2. Notify Your Property Manager: Send a written notice to your landlord or real estate agent immediately. Under Australian tenancy laws, landlords are required to keep properties in a state of good repair. 3. Assess the Ventilation: Ensure that exhaust fans are running and windows are opened whenever weather permits to reduce indoor humidity. 4. Do Not Attempt Major Removal: For large-scale mould infestations, do not try to scrub the area yourself with harsh chemicals. This can release more spores into the air and worsen your asthma symptoms. Professional remediation is often required to ensure the root cause is solved. 5. Consult a Professional: Contact experts like Clean Dry Restore to assess the severity of the contamination and provide a formal report for your property manager. ## The Importance of Professional Remediation Mould is a living organism that thrives deep within porous materials like drywall, carpet, and timber. Simply wiping the surface with vinegar or bleach often leaves the fungal roots intact, allowing it to return within days or weeks. Professional restoration services use industrial-grade equipment, such as HEPA-filtered vacuums and moisture detection sensors, to identify hidden moisture pockets and safely remove spores. By addressing the source of the moisture—whether it is an external structural issue or an internal ventilation problem—we ensure the property remains safe for tenants to occupy long-term. ## Frequently Asked Questions ### Is my landlord responsible for mould removal? In most Australian states, if the mould is caused by a structural issue like a leaking roof or plumbing, the landlord is responsible for repairs and remediation. However, if it is caused by a lack of tenant ventilation, the responsibility may be shared. Always check your local tenancy tribunal guidelines. ### Can mould exacerbate asthma even if I cannot see it? Yes, mould can grow inside wall cavities, under floors, or in ceiling spaces. If you notice a persistent 'musty' smell but cannot see growth, it is still likely affecting your indoor air quality. ### How quickly should a landlord respond to a mould report? Mould is considered a health and safety issue. Once reported, your landlord should investigate and commence repairs within a reasonable timeframe, as it directly impacts your ability to live in the premises safely. ### Should I vacate the property if the mould is severe? If you are having frequent asthma attacks, it is crucial to consult your GP. If they deem the living environment hazardous, you should discuss your options with your property manager or legal tenancy advice service.
