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
