The key to mould and fungus control is dampness and moisture control. You need to solve moisture problems before they become mould and fungus problems. Fix leaks in plumbing and leaks in the building envelope as soon as possible.
- Watch for condensation and wet spots. Fix source of moisture problem as soon as possible.
- Prevent moisture due to ç 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 inspections and maintenance as scheduled.
- Clean and dry wet or damp spots within 48 hours.
- Don't let foundations stay wet. Provide drainage and slope the ground away from the foundation.
