Preventing mold growth is better and cheaper than trying to remove it after growth.
Steps you can take to prevent mold growth in your home
Anything you can do to reduce the moisture content in your home will reduce the possibility of mold growth. Moisture is the only element mold needs that you can control. The other two – air and food source – are beyond your control.
Repair leaking pipes, roofs and window sills as soon as you notice anything. Mold usually takes consistent moisture to take hold and grow. A leak won’t cause mold to grow if you clean up the water and repair the problem immediately.
Make sure your house has positive drainage. Rain should drain away from your house, not into the basement.
Keep areas such as sinks, showers, laundry rooms and bathtubs free of standing water.
Consider ways to keep your home’s humidity between below 60 % because mold loves high humidity and won’t grow when it’s dry inside. You may want to consider a dehumidifier, an air conditioner, or both.
Consider areas and corners where cold air meets warm, creating moisture.
Inspect your home’s exterior regularly, paying attention to any areas where moisture could find a way into your home. Fix them as soon as possible. Make sure the house is well ventilated.
