The seven principles to a healthy home, according to the NCHH (National Center of Healthy Housing):
1. Keep it Dry.
Prevent water from entering your home through leaks in roofing systems, rain water from entering the home due to poor drainage and check your interior plumbing for any leaking.
2. Keep it Clean.
3. Keep it Safe.
Store poisons out of the reach of children and properly label. Secure loose rugs and keep children’s play areas free from hard or sharp surfaces. Install smoke and carbon monoxide detectors and keep fire extinguishers on hand.
4. Keep it Well-Ventilated.
Ventilate bathrooms and kitchens and use whole-house ventilation for supplying fresh air to reduce the concentration of contaminants in the home.
5. Keep it Pest-Free.
All pests look for food, water and shelter. Seal cracks and openings throughout the home and store food in pest-resistant containers. If needed, then use sticky-traps and baits in closed containers, along with least-toxic pesticides such as boric acid powder.
6. Keep it Contaminant-Free.
Reduce lead-related hazards in pre-1978 homes by fixing deteriorated paint, and keeping floors and window areas clean using a wet-cleaning approach. Test your home for radon, a naturally occurring dangerous gas that enters homes through soil, crawl spaces and foundation cracks. Install a radon removal system if levels above the EPA action-level are detected.
7. Keep it Well-Maintained
Inspect, clean and repair your home routinely. Take care of minor repairs and problems before they become large repairs and problems.
