What Mould Risks Does Ceiling Water Damage Create?
6 mould risks develop from untreated ceiling water damage in Ajax properties.
- Aspergillus on wet drywall paper: The most common indoor mould colonizes drywall within 24 hours at relative humidity above 60%
- Stachybotrys (black mould) on prolonged leaks: Appears after 7 to 12 days of continuous moisture on cellulose materials
- Hidden mould above drywall: Mould grows on the backside of ceiling panels, invisible from below
- Insulation mould contamination: Kraft paper facing and cellulose fibres provide nutrients for rapid mould expansion
- HVAC cross-contamination: Mould spores enter ductwork above ceilings, spreading to every room in the home
- Structural wood rot fungi: Ceiling joists develop wood-decay fungi after 30 or more days of moisture exposure
