For Sydney residents, the battle against mould is an ongoing one. Our beautiful harbour city boasts a temperate climate, perfect for many things, but unfortunately, also ideal for mould growth. Mould spores are ever-present in the air, and when they find a damp, warm environment, they quickly establish themselves. This can lead to unsightly blemishes, unpleasant odours, and even health problems.
At Local Property Inspections, we understand the importance of a healthy home. That\’s why we\’ve put together this comprehensive guide on how to remove mould, treat the affected area, and prevent its unwelcome return.
Understanding Mould Growth in Sydney Homes
Before we delve into solutions, let\’s explore the main culprits behind mould growth in Sydney houses:
- Moisture: Mould thrives in damp environments. Leaky pipes, condensation on windows, poor ventilation in bathrooms and kitchens, and rising damp from the ground are all common causes of excess moisture in Sydney homes.
- Lack of Ventilation: Homes with inadequate ventilation trap moisture indoors, creating a breeding ground for mould.
- Building Materials: Certain building materials, like porous drywall or timber framing, can absorb and retain moisture, making them susceptible to mould growth.
Types of Sydney Houses and Their Mould Risks
The type of house you live in and its construction methods can influence mould growth. Here\’s a breakdown of some common Sydney house types and their associated mould risks:
- Free-Standing Houses: These houses tend to have better ventilation compared to units or terraces. However, leaks around windows, doors, and the roof can create moisture issues. Mould growth can also occur in poorly ventilated areas like bathrooms and laundry rooms.
- Terraces and Townhouses: Sharing walls with neighbouring properties can limit airflow and increase condensation, particularly in shared walls. Terraces with limited external space might also have issues with drying laundry efficiently. Be sure to check for mould growth in shared walls, especially around bathrooms and kitchens.
- Apartments: Apartments often have limited ventilation due to a lack of external walls. Mould growth can be a concern in bathrooms, kitchens, and laundry rooms, especially if proper exhaust isn\’t used.
- Older Brick Houses: Solid brick homes can be susceptible to rising damp if the DPC (Damp Proof Course) is damaged or ineffective. This can lead to mould growth on internal walls, particularly at lower levels.
- Modern Constructions: Modern houses often incorporate good ventilation practices, but improper construction or faulty building materials can trap moisture and create mould issues.
How to Remove Mould
If you\’ve discovered mould in your Sydney home, don\’t despair! Here\’s a step-by-step guide on how to remove it safely and effectively:
- Safety First: Mould spores can irritate the respiratory system. Before tackling the mould, wear protective gear like gloves, a respirator, and safety goggles.
- Identify the Source: Address the underlying cause of the moisture problem before removing the mould. Fix leaky pipes, improve ventilation, and identify any areas with rising damp.
- Containment: To prevent spores from spreading, seal off the affected area with plastic sheeting and tape.
- Small Mould Patches: For small mould patches (less than 1 square metre), you can use a solution of white vinegar and water (mix equal parts) or a commercial mould remover. Apply the solution to the affected area, scrub gently with a stiff brush, and then rinse thoroughly with clean water. Dispose of cloths and wipes used for cleaning in a sealed bag.
- Larger Mould Infestations: For extensive mould growth (more than 1 square metre) or mould on porous surfaces like ceilings or carpet, professional help is recommended. Professionals have the expertise and equipment to safely remove large mould infestations and ensure proper remediation.
Treating the Affected Area
Once the mould is removed, the affected area needs to be treated to prevent regrowth. Here\’s what you need to do:
- Allow the Area to Dry Completely: Use fans and dehumidifiers to dry the area thoroughly. Mould cannot grow in a dry environment.
- Kill Remaining Spores: Apply a fungicidal solution after the area is dry. This will kill any remaining mould spores and prevent them from germinating.
Preventing Mould from Returning
Here are some key strategies to prevent mould from returning to your Sydney home:
- Improve Ventilation: Ensure proper ventilation in your home, particularly in bathrooms, kitchens, and laundry rooms. Open windows regularly, use exhaust fans during showers and cooking, and consider installing mechanical ventilation systems if needed.
- Control Moisture Levels: Address any sources of moisture in your home promptly. Fix leaky pipes, ensure proper drainage around the house, and use de
- Control Moisture Levels (continued): use dehumidifiers in damp areas to control moisture levels.
- Maintain Proper Drainage: Ensure gutters, downpipes, and drains are clear and functioning properly to prevent water build-up around the house foundation.
- Dry Laundry Properly: Don\’t hang wet laundry indoors for extended periods. Use a clothes dryer or a vented drying rack to prevent moisture build-up.
- Reduce Indoor Plants: While lovely, a large number of indoor plants can contribute to indoor humidity.
- Regular Inspections: Regularly inspect your home for signs of mould growth, particularly in bathrooms, kitchens, laundry rooms, under sinks, and around windows. Early detection and treatment can prevent larger problems.
The Importance of Professional Help
While you can tackle small mould infestations yourself, there are situations where professional help is crucial:
- Extensive Mould Growth: If the mould covers a large area (more than 1 square metre), professional removal is essential. Professionals have the training and equipment to safely remove large infestations and ensure thorough remediation.
- Porous Surfaces: Mould on porous surfaces like ceilings, carpet, or timber requires specialized techniques and products for proper removal. Professionals have the expertise to handle these situations effectively.
- Health Concerns: If you have respiratory problems or allergies, avoid disturbing mould as it can exacerbate symptoms. Professionals can remove mould safely and minimize your exposure to spores.
- Hidden Mould: Mould can sometimes grow behind walls or under floorboards. Professionals can use specialized equipment to locate hidden mould growth and address it appropriately.
