CASE STUDY: Hidden Moisture, Lasting Impact
Water damage and mould contamination often go hand in hand, especially after severe weather events.
On 9th September 2025, Elite Restoration attended a property following reports of visible black mould growth in internal areas.
The root cause was prolonged moisture exposure after a major storm event, where wind-driven rain entered through the roof cavity and structural joints.
Moisture became trapped within the building structure, particularly under metal roofing and around slab-to-wall junctions, creating the perfect environment for mould to thrive.
Over time, this led to extensive mould colonisation in the roof cavity, along with visible growth and material deterioration in internal areas such as ceilings and window zones.
Laboratory testing confirmed elevated mould spore levels, indicating active contamination rather than dormant presence.
This situation highlights the importance of thorough remediation, especially following Category 3 water intrusion involving contaminated floodwater.
Without proper drying and removal of affected materials, residual moisture and salts can continue to drive mould regrowth long after the initial event.
Following industry standards such as IICRC S500 and S520 ensures that contamination is properly addressed, restoring a safe and healthy indoor environment.
