Mould Grows Fast After a Flood

Mould can begin to grow within 24 to 48 hours of a flood. Mould needs moisture, organic material such as drywall paper or wood, and time. A water-damaged basement or wall cavity supplies all three.

Mould remediation removes mould and the conditions that cause it. IICRC S520 is the industry reference standard for mould remediation.

Moisture mapping and thermal imaging to find hidden mould
Containment barriers to limit spore spread
HEPA air scrubbers and negative air pressure
Removal of mould-affected porous materials
Cleaning and antimicrobial treatment of surfaces
Post-remediation verification before re-occupancy

Mould Remediation Process

Inspection Method: Visual inspection, moisture meter, thermal imaging camera
Containment Equipment: Polyethylene barriers and negative air pressure
Air filtration Equipment: HEPA air scrubbers
Material removal Applies to: Mould-affected drywall, insulation and carpet
Cleaning Method: HEPA vacuuming and damp wiping of surfaces
Moisture control Prevents regrowth: Structural drying to the dry standard
Verification Timing: After cleaning and before containment is removed

Conditions for Mould Growth

Moisture Requirement: Materials staying wet beyond 24 to 48 hours
Food source Examples: Drywall paper, wood framing, carpet, insulation facing
Indoor relative humidity Health Canada guidance: 30% to 50%
Prevention Most effective step: Fast extraction and complete structural drying

Mould Remediation FAQs

Signs are a musty odour, dark spots on walls or ceilings and unexplained allergy symptoms. Mould also grows inside wall cavities before it is visible, so a moisture inspection is recommended after a flood.

Yes. Drywall and insulation hold moisture, and wall cavities stay wet longer than surfaces. Moisture meters and thermal imaging cameras locate hidden moisture without unnecessary demolition.

Mould can irritate airways and trigger allergies and asthma symptoms. Children, older adults and people with respiratory conditions are most affected.
