MOLD REMOVAL > PREVENTION TIPS
The key to mold prevention and mold & mildew removal is to eliminate moisture. Basements must be dried out, and humidity levels should be maintained at about 50% relative humidity or lower to prevent mold growth. Dehumidifiers can be very useful. Vapor steam cleaning or vacuuming with High Efficiency Particulate Absolute (HEPA) filter vacuums can reduce mold spore concentrations in damp areas and carpets, but if not done properly mold spores can remain or be spread into the air.
Prevention Tips
- Fix leaky plumbing and leaks in the building envelopes as soon as possible
- Watch for condensation and wet spots. Fix source(s) of moisture problem(s) as soon as possible
- Prevent moisture due to condensation by increasing surface temperature or reducing the moisture level in air (humidity). To increase surface temperature, insulate or increase air circulation. To reduce the moisture level in air, repair leaks, increase ventilation (if outside air is cold and dry), or dehumidify (if outdoor air is warm and humid)
- Keep heating, ventilation, and air conditioning (HVAC) drip pans clean, flowing properly and unobstructed.
- Vent moisture-generating appliances, such as dryers, to the outside where possible.
- Maintain low indoor humidity, below 60% relative humidity (RH), ideally 30-50%, if possible.
- Perform regular building/HVAC inspections and maintenance as scheduled.
- Clean and dry wet or damp spots within 48 hours.
- Dont let foundations stay wet. Provide drainage and slope the ground away from the foundation.
