Easy-To-Follow Tips To Prevent Mold
1. Periodically clean areas known to collect water or moisture such as bathrooms, laundry room, or other suspected areas. Wipe lavatory bowl, shower stall, and bathtub immediately after use.
2. Turn on the bathroom ventilator for a reasonable period of time after bathing or showering to remove moisture that may have absorbed into the walls and other surfaces.
3. Wipe all surfaces in kitchen and bathroom areas with an approved disinfectant regularly and regularly vacuum areas including are sofas, chairs, curtains, carpets, bedding, fabric walls, etc. with a vacuum that utilizes a HEPA (High Efficiency Particulate Arrestor).
4. Hire trained professionals to periodically clean A/C indoor cooling coils and other appropriate components. Mold can be traced to microorganisms that grow in home heating and cooling systems and humidifiers. Be sure to be using only high efficiency air filters in your air conditioning system.
5. Install Energy Recovery Ventilators (E.R.V.) or inline dehumidifier systems in the central air conditioning system ducts. Doing so will greatly reduce indoor air-borne particulate contamination, allergens, molds, indoor humidity, Sick Building Syndrome (S.B.S.), etc.
6. Avoid water accumulation next to or beneath the exterior of the structure. Re-direct lawn and garden sprinkler systems away from the structure to help prevent continual dampness on or adjacent to the structure.
7. Pressure wash sidewalks, patios, exterior walls, and window frames when mold like substances appear to help control fungal activity outdoors.
8. Trim or cut back vegetation and foliage that that is in contact with or growing on the structure. Allow 18” distance from structure to any foliage.
9. Clean gutter systems and roof areas regularly to help control leaf accumulation.
10. Direct all water run-offs from roof away from structure by making sure splash blocks are properly placed at downspouts.
11. Keep humidity levels as low as you can—no higher than 50%–all day long by using an air conditioner or dehumidifier. Humidity levels can change over the course of a day so be sure to check humidity levels more than once a day.
12. Be sure your home has enough ventilation. Use exhaust fans in your kitchen, bathroom, and laundry room that expel air and its contaminants outside your home.
13. Fix any leaks in your home’s roof, walls, or plumbing to limit the amount of moisture in your home.
14. Clean up and dry out your home thoroughly and quickly (within 24–48 hours) after flooding.
14. Add mold inhibitors to paints before painting.
15. Clean bathrooms with mold-killing products.
16. Remove or replace carpets and upholstery that have been soaked and cannot be dried promptly. Consider not using carpet in rooms or areas like bathrooms or basements that may have a lot of moisture.
