It may take several weeks, even longer in winter, to completely dry out your home. To avoid trapping moisture inside the home, everything that is wet and able to be moved should be taken outside to dry.
- In dry weather, open all doors and windows
- On wet days, leave windows partly open as the inside of the house will only dry when moisture can get out
- If you have heaters, turn them on in as many rooms as possible and leave windows open, however do not use more than one heater per room as too much heat may warp and crack wood
- Apply commercial grade cleaner
- After cleaning surfaces, go over the entire room with disinfectant
- Clean walls from the bottom up
- If you have taped the windows, remove tape and use glass cleaner to remove adhesive
- Look for trapped mud in less obvious places for example under shower trays, baths, benches, bottom shelves)
- Hose or pump out mud or water, then dry as quickly as possible
- Ignore any mould growing until drying is complete, then remove with household bleach, seek advice if you or your family suffer from asthma or respiratory diseases
- It is important that wood and particle board dries quickly
- To assist drying, cut back or remove plants obstructing vents
- Remove foundation cladding such as baseboards or sheet materials for ventilation
- Dig a drainage pit or pump out water that collects under or around your home
- Where you cannot access water in walls or under floorboards, cut a trap door
