The First Hour — Safety Before Everything
A flooded home presents serious hazards that must be addressed before you assess or begin any cleanup. The most critical: electricity. Water and live electrical systems are a lethal combination. If there is any chance water has reached electrical outlets, the DB board, or wiring — or if you are unsure — switch off the main breaker at the distribution board before entering any flooded area. If the breaker is inaccessible or itself submerged, contact your municipality's emergency number or a licensed electrician before entering.
Also check for structural damage before re-entering: cracks in walls or foundations that appeared suddenly, a sagging ceiling, or visibly bowed walls indicate potential collapse risk. If you are unsure about structural integrity, wait for a professional assessment.
If the flood was caused by a municipal drainage or sewage system failure, the water may be contaminated. Wear rubber gloves and boots, and treat all floodwater as potentially hazardous until you know its source.
Document Everything Before Touching Anything
Your insurance claim depends on documentation. Before moving furniture, mopping floors, or removing any damaged items:
- Photograph and video every room showing the water level and all visible damage
- Photograph damaged furniture, appliances, flooring, walls, and ceilings individually
- Note the water source and the approximate time flooding began and ended
- Save any communications from municipality, neighbours, or emergency services about the event
Do not discard any damaged items until an assessor from your insurer has visited or explicitly told you to proceed. Some insurers require on-site assessment before any cleanup begins.
Contact Your Insurer Immediately
Most home insurance policies have a 24-hour emergency line. Call it as soon as people are safe and before starting any cleanup. Report:
- The date and cause of the flooding (burst pipe, storm drain overflow, roof leak, etc.)
- Which rooms and items have been affected
- Whether the property is safe to occupy
Ask specifically whether emergency drying and extraction services are covered and whether the insurer has a preferred contractor for flood damage remediation. Many policies include emergency mitigation cover — meaning the insurer will pay for immediate water extraction and drying to prevent further damage, even before the full claim is assessed.
South African home insurance policies typically cover sudden and accidental damage from burst pipes, geyser failure, and storm-related flooding. Gradual damage from a leaking roof that was not addressed is usually excluded. Know your policy — the cause of the flooding significantly affects your claim prospects.
Water Extraction and Drying — Act Within 24 to 48 Hours
The faster you remove standing water and begin drying, the less secondary damage you will face. Mould begins growing in wet environments within 24 to 48 hours. Once mould is established in flooring, wall cavities, or ceiling boards, remediation becomes significantly more expensive and complex.
- Remove standing water using a wet-dry vacuum, mop, or if volumes are large, a submersible pump (available from tool hire companies)
- Open windows and doors to maximise airflow — but not if outside humidity is very high, as this can slow drying
- Run fans and dehumidifiers continuously — industrial dehumidifiers can be hired for R300 to R600 per day
- Remove soaked rugs, carpets, and soft furnishings — these hold water and accelerate mould growth. Carpets that have been wet for more than 48 hours are almost always unsalvageable and should be discarded
- Lift wooden floorboards where possible to allow the subfloor to dry — trapped moisture under boards causes warping and rot
Assess Structural and Material Damage
Once the property is dry, a proper damage assessment can begin:
- Plasterwork — wet plaster absorbs and holds water. Bubbling, crumbling, or hollow-sounding plaster after drying will need to be hacked off and reapplied. Painting over damp plaster traps moisture and causes ongoing problems.
- Timber — window frames, door frames, and timber flooring that have been saturated may warp or rot. Assess after full drying; some can be saved with sanding and sealing, others need replacement.
- Ceiling boards — water-damaged ceiling boards (particularly gypsum board) will sag or disintegrate. Replace rather than repair.
- Electrical — even after water has dried, flooded electrical components (plugs, light fittings, wiring in wet walls) must be inspected by a licensed electrician before being used. An electrician will need to issue a new Certificate of Compliance once repairs are complete.
Mould Prevention and Remediation
If mould appears — visible as black, green, or white fuzzy patches with a musty smell — act quickly. Surface mould on hard surfaces can be treated with a diluted bleach solution (1 part bleach to 10 parts water) and scrubbing. Mould that has penetrated porous materials (plaster, timber, ceiling boards, soft furnishings) typically cannot be eliminated without removing and replacing the affected material.
For significant mould contamination, a professional mould remediation company is worth engaging. Attempting to paint over mould without proper treatment will result in it returning.
Preventing a Recurrence
Once the immediate damage is addressed, identify and fix the root cause:
- Burst pipes — insulate exposed pipes, particularly in frost-prone areas; replace aging galvanised pipes that are corroding internally
- Geyser failure — replace geysers more than 10 years old; ensure the drip tray drain is clear and connected to a drain point outside the roof space
- Storm water flooding — check that gutters and downpipes are clear and that ground drainage slopes away from the house
- Rising damp — address the source (usually failed waterproofing or subfloor ventilation) before replastering
The Bottom Line
Speed is the most important factor in flood damage recovery. Document before you touch anything, contact your insurer within hours, get the water out and drying started within 24 hours, and address the root cause before closing up repaired surfaces. Most flood damage is recoverable if handled correctly in the first 48 hours; much of it becomes permanent if left.
