To prevent mold growth in your home Keep the humidity levels in your home as low as possible, no more than 50%, throughout the day. Make sure the air in your home flows freely. Correct any leaks in the roof, walls, or pipes in your home so mold doesn't have moisture to grow. Lowering moisture levels could significantly reduce the potential for mold growth.
Removing excess moisture from your property would prevent mold from reappearing. Keep your environment as dry as possible by isolating surfaces that are prone to condensation, cleaning any residual liquid, and properly repairing leaks. Make sure to dry the fabric properly before storing or using it. To stop condensation in your home, you must remove excess moisture.
You can do this by keeping windows dry, using vents and fans in the bathroom and around the oven, and running a dehumidifier. Make sure all the thermostats in your home are set to the same temperature. The EPA recommends keeping indoor humidity between 30 and 60 percent. You can measure humidity with a moisture meter purchased at your local hardware store.
You can also detect high humidity simply by paying attention to potential problem areas in your home. Telltale signs of excessive humidity include condensation on windows, pipes and walls. If you notice condensation, dry the surface immediately and go to the moisture source (for example, turn off a humidifier if water appears inside nearby windows).
