  1. Make your home mold-resistant: Check for problem areas in your home, such as the basement, condensation on your window upstairs or leaking faucets. Once you do an audit of your home, you can begin to take concrete steps to get rid of mold or at least prevent it from spreading.
  2. Eliminate moisture from your home. Mold needs warmth and humidity to grow, so get rid of any seepages after a heavy shower or leakages or water accumulation in carpets, furniture or bedding. Don’t leave wet items like clothes in the washing machine or any other around lest they develop mold.
  3. Ensure good ventilation in your home. Check that your kitchen, laundry room and bathroom are well-ventilated as these parts of your home are considered high-moisture. Stoves and clothes dryers attract moisture; hence ventilation in these parts is essential. Install dehumidifiers and AC units to suck up the moisture and clean them periodically to make your home is energy-efficient humidity-free. Keep the windows open or use an exhaust fan.
  4. Use mold-resistant products. Whether you’re renovating your existing home or building a new one, it helps to use mold-resistant products such as drywall or mold inhibitors if using paints. Drywall helps in moisture-prone areas like kitchens, bathrooms and laundry rooms.
  5. Check indoor humidity levels. According to the US Environment Protection Agency (EPA),indoor humidity levels shouldn’t exceed 60%. Humidity can be detected at home by condensation found on walls, windows and pipes. To eliminate condensation, close leaky taps, repair them and dry the area.
  6. Reroute water away from your home. If your home doesn’t have a natural slope that makes it dry and free of water around the foundation, create a water path with a slope so that it doesn’t find its way into your basement or foundation.


Now that you’ve come closer to knowing a lot about how to remove black mold on wood, you can prepare yourself and your home to be entirely mold-free.
