Mould Growth in Humid Months: Prevention and Remediation

Proactive Protection When Moisture Rises

Condensation buildup on a window—sign of high indoor humidity and potential mould risk

When summer humidity hits, mould becomes more than just an eyesore, it can threaten your home’s structure and your health. At Paul Davis, we know how important it is to stay ahead of this silent intruder.


Why Mould Thrives in Humid Weather

Warm, damp environments create the perfect breeding ground for mould. Basements, bathrooms, kitchens, and attics are especially vulnerable. If unchecked, mould can:


  • Damage drywall, wood, and insulation
  • Trigger respiratory issues and allergies
  • Spread rapidly behind walls and under flooring


How to Prevent Mould During Humid Months


Protect your property with these steps:


  1. Ventilate often. Use fans and open windows, especially in bathrooms and kitchens.
  2. Control humidity. Keep indoor humidity below 50% with dehumidifiers.
  3. Fix leaks immediately. Even small drips can fuel mould growth.
  4. Use mould-resistant products. Especially in renovations or repairs.
  5. Monitor high-risk areas. Inspect basements and attics regularly.
