What to Do After Major Water Ingress | Step-by-Step Emergency Guide

The 48-Hour Mould Prevention Window

✓ Critical Timeline: Mould spores germinate and proliferate within wet plasterboard, timber framing, and carpets within 24 to 48 hours of water saturation.

✓ Safety First: Never enter standing water until electrical power circuits have been isolated by a qualified electrician or building manager.

Immediate 5-Step Action Protocol

Step 1: Ensure Life Safety & Electrical Isolation: Isolate electrical switchboards for affected zones. If water is dripping through light fixtures or down switchboards, do not touch switches.
Step 2: Stop the Water Source: If from internal plumbing, isolate the main water stopcock. If from storm roof failure, engage a 24/7 emergency make-safe team for immediate tarping and water diversion.
Step 3: Document Everything for Insurance: Take high-resolution photos and videos of water entry points, standing water levels, damaged inventory, and affected structural elements BEFORE cleaning up.
Step 4: Immediate Water Extraction & Air Movement: Engage commercial restoration equipment (LGR dehumidifiers and high-volume axial air movers) to pull moisture from deep within building sub-screeds and cavities.
Step 5: Forensic Diagnostic Leak Tracing: Once the immediate emergency is stabilized, conduct an engineered investigation to determine why the building envelope failed and install permanent rectification.
