Mould Remediation

Fast, Reliable, and Expert Restoration Services

Mould and contaminants can cause serious health issues and damage to your property. Our licensed experts quickly assess, remove, and prevent mould growth, keeping your home or business safe and compliant.

Our licensed teams secure your property, limit further damage, and get you back to normal—safely and efficiently.

  • Mould is a type of fungus that grows on walls, ceilings, floors, and hidden spaces where moisture is present. It can cause allergic reactions, respiratory problems, and structural damage if left untreated. Early detection is essential to protect your home or business and prevent costly repairs.

  • Mould grows when moisture combines with organic materials like wood, drywall, or insulation. Common areas include bathrooms, kitchens, basements, crawl spaces, and behind walls or cabinets. Mould can appear as spots, streaks, or discolouration and may emit a musty odour.

  • Small surface mould can sometimes be cleaned safely with proper precautions, but larger infestations require licensed mould remediation experts. Professionals ensure spores are fully removed, moisture sources fixed, and your property is safe for occupants.

  • Remediation should occur as soon as mould is discovered or after water damage, leaks, or storms. Delaying treatment increases health risks, property damage, and insurance complications.

  • Mould removal typically refers to cleaning visible surface mould, while mould remediation is a comprehensive process. Remediation includes assessing the infestation, removing affected materials, treating the area, fixing moisture issues, and preventing future growth.

  • Prevent mould by controlling moisture, fixing leaks promptly, improving ventilation, and monitoring humidity levels. Regular inspections after storms or water damage help catch mould early before it becomes a serious problem.

  • DIY mould removal is only recommended for small, contained patches. For larger infestations, professional remediation is safer and more effective. Experts remove hidden mould, treat spores, and ensure moisture issues are resolved, reducing the risk of recurrence.
