Cleaning Up After a Flood
Health and Safety
- Wear protective equipment: Rubber boots, gloves, face mask, eye protection
- Assume all floodwater is contaminated with sewage and chemicals
- Ventilate your property before spending extended time inside
- Do not turn on electricity until an electrician has checked the installation
- Photograph all damage before cleaning for insurance purposes
Step-by-Step Cleanup
- Pump out standing water (hire a pump or ask your insurer)
- Remove damaged items: Carpets, underlay, plasterboard below the flood line
- Hose down hard surfaces with clean water
- Disinfect: Use a bleach solution on hard surfaces
- Dry out thoroughly: Open windows, use dehumidifiers and fans
- Check for structural damage: Look for cracks, bulging walls, damaged foundations
Drying Out
A typical flood-damaged house takes 6-12 months to dry out properly. Rushing redecoration before drying is complete will trap moisture and cause damp and mould.
- Professional drying services can speed the process
- Industrial dehumidifiers are much faster than domestic ones
- Keep heating on low (15-20C) with windows open
- Monitor moisture levels with a damp meter
What to Keep and What to Discard
- Discard: Carpets, soft furnishings, mattresses, chipboard furniture, standard plasterboard
- Keep and clean: Solid wood furniture, metal items, ceramic tiles, stone surfaces
- Professional cleaning: Curtains, clothes, leather goods
