Basic steps to prevent and reduce mold growth
Mold needs moisture to grow. Controlling the moisture and keeping the home dry prevents the growth of mold.
- Check your home for signs of moisture and molds.
- Find out if water is coming in from the outside and if substantial moisture is produced inside the home.
- Fix any water leaks promptly.
- Think of the different ways moisture is produced inside the home (for example, cooking, bathing, plant jungle). Remove the moisture as it is produced by using exhaust fans. In the absence of fans, open windows for a short time, but note that the wind can push the moisture to other parts of the home.
- Measure how much moisture is in the air. To find the relative humidity in your home, you'll need a hygrometer. You can buy one at a hardware store or electronics store. A hygrometer costs from $10 to $60. Relative humidity in the home should be under 45 per cent in the winter (or lower to avoid condensation on windows). If necessary, use a dehumidifier to lower the relative humidity.
- Reduce the amount of stored materials, especially items that are no longer used. Molds grow on fabrics, paper, wood and practically anything that collects dust and holds moisture.
