When disinfecting with bleach:
- never use more than one cup bleach to one gallon water;
- never mix bleach with ammonia or other cleaner;
- wear rubber boots, gloves, goggles and a mask;
- open windows and doors when weather permits.
Do not use fans; if mold already exists, it could spread.
Fix leaks in pipes and any damp areas around tubs and sinks.
Rebuild using water-resistant materials.
Prevent water seepage from outdoors by installing or reinforcing rain spouts.
