Mould growth leads to health risks and structural damage. It spreads in damp conditions, making prevention necessary. Controlling moisture, improving ventilation, and using the right materials reduce the risk.
Follow these steps to keep your home safe.
1. Manage Moisture Levels
Mould thrives in damp environments. Maintain indoor humidity below 60% with dehumidifiers, air conditioners, or moisture absorbers. Ventilate high-moisture areas like bathrooms, kitchens, and basements using exhaust fans and open windows when possible.
Dry wet surfaces immediately to prevent excess moisture from seeping into walls and flooring. Check indoor plants, as overwatering can increase humidity levels.
2. Fix Leaks Immediately
Leaks allow moisture to accumulate, creating ideal mould conditions. Inspect plumbing, roofing, and windows regularly. Fix leaks quickly to prevent water damage and mould growth.
Examine hidden areas such as under sinks, behind washing machines, and inside wall cavities where leaks may go unnoticed. Address condensation buildup on pipes and windows by insulating exposed surfaces.
3. Improve Ventilation
Stagnant air supports mould growth. Increase airflow by using fans, keeping windows open when possible, and placing furniture away from walls. Ventilation lowers dampness and prevents mould in hidden areas.
Exhaust fans should be installed in high-moisture areas and cleaned regularly to maintain efficiency. Keep wardrobes and storage spaces ventilated to prevent trapped moisture from damaging clothing and belongings.
4. Monitor Humidity
Use a hygrometer to track humidity. If levels exceed 60%, improve ventilation or use moisture-absorbing materials like silica gel. Wardrobes, cupboards, and storage areas benefit from controlled humidity to prevent mould.
Consider installing smart humidity sensors that alert homeowners when moisture levels become too high. In persistently humid climates, investing in a whole-house dehumidifier can provide long-term moisture control.
5. Keep Surfaces Dry and Clean
Mould spores settle on damp surfaces. Clean and dry areas prone to moisture, including window sills, shower curtains, and kitchen counters. Dry towels, bath mats, and other fabrics completely before storing.
Regularly wipe down air conditioning vents and ceiling fans to prevent dust and moisture accumulation. Clean fridge drip trays and dishwashers, as these can retain excess water and encourage mould growth.
6. Use Mould-Resistant Materials
During renovations, choose materials designed to resist mould. Mould-resistant drywall, waterproof paint, and non-porous flooring help prevent growth, particularly in moisture-prone spaces like bathrooms and laundries.
Opt for moisture-resistant insulation in attics and crawl spaces to prevent dampness from seeping into walls. Consider using antimicrobial sealants in kitchens and bathrooms to create a barrier against mould.
7. Maintain Proper Drainage
Water pooling around foundations raises indoor moisture levels. Keep gutters and downspouts clear to direct water away. Proper grading prevents water from seeping into basements and crawl spaces.
Check outdoor taps and irrigation systems for leaks, as they can contribute to moisture accumulation near the home. Ensure that downspouts extend at least two metres away from the foundation to reduce water infiltration risks.
8. Store Items Correctly
Storage conditions impact mould risk. Keep belongings off the ground and spaced for airflow. Store clothing and paper items in airtight containers to prevent moisture absorption. Avoid overcrowding to maintain ventilation.
Use desiccants in storage areas to absorb excess moisture. Regularly inspect stored items, especially those in basements and garages, as these areas are more susceptible to humidity buildup.
9. Inspect Your Home Regularly
Check for moisture, condensation, and leaks under sinks, behind appliances, and around windows. Identifying issues early prevents costly repairs and mould spread. Look for musty odours, which can indicate hidden mould growth.
Inspect attic spaces for signs of roof leaks or poor insulation that could lead to moisture problems. Pay attention to wall discolouration, as this can be an early sign of water damage and mould development.
10. Remove Mould Immediately
If mould appears, clean it with vinegar or hydrogen peroxide. Avoid bleach, as it may not prevent regrowth. For persistent mould, consult a professional to identify and resolve the cause. Address the root moisture issue to prevent recurrence.
Use HEPA vacuum cleaners to remove mould spores from affected areas without spreading them further. Ensure that the area is thoroughly dried after cleaning to prevent residual moisture from allowing mould to regrow.
Prevent Mould and Protect Your Home
Mould prevention requires moisture control, ventilation, and routine inspections. These steps help homeowners avoid expensive damage and maintain healthy living spaces.
Taking proactive measures ensures long-term protection against structural decay and health risks associated with mould exposure.
