1. Identify moisture-prone areas
High-risk areas are those that are subject to high humidity and moisture levels. These include bathrooms and kitchens, laundry rooms, foundation, attics, basements, crawl spaces, garages, etc. A quarterly mold check should detect potential problems before they become infested and spread. Check behind your washer and dryer, under sinks, walls and ceilings, and around windows.
2. Reduce your indoor humidity
When the humidity rises, so does the potential for mold growth. You can keep your home's indoor humidity at safe levels by implementing a few minor changes. Installing a dehumidifier or air conditioner will ensure that excess moisture does not build up and mold never has a chance to flourish. Consider purchasing a unit with a built-in filter to prevent mildew and mold spores from circulating through the air.
3. Keep the air circulating
Many heating and cooling systems don't ventilate air, which can lead to higher levels of moisture condensation. Yet mold thrives in still, damp, humid environments. When air flows freely through the ventilation system in your home, mold will not have the opportunity to start growing in the first place. ERV and HRV systems can efficiently remove contaminated air and bring fresh, clean air from outside.
4. Invest in mold-resistant materials
Highly water-absorbent building materials, such as wood and carpet, provide an ideal environment for mold to grow. Since water is usually the primary requirement for mold growth, having a water-resistant material will help prevent it from getting into your walls, ceiling, and floors. Consider using paints that contain mold inhibitor agents to prevent mold growth further. Mold-resistant drywall is also a great product that is not susceptible to moisture.
5. Prevent leaks and clean up spills
Leaky pipes and faucets can be a real mold threat, especially if left unattended for over a day. If you notice a leak or any water drainage, fix it promptly and clean up the mess immediately. The US Environmental Protection Agency (EPA) recommends drying a spill, leak, or flood not later than 48 hours after the occurrence. Also, be sure to frequently check your roof, windows, and other outside sources of moisture to prevent further dampness.
6. Install a gutter guard system
Clogged gutters and overflowing water can lead to water damage around your home. Leaves, twigs, and other debris can accumulate and block the gutters, resulting in water falling on the top of the wall and seeping into it, creating a potential breeding ground for mold. For these reasons, keeping your gutters clean and properly functioning is essential. Installing a gutter guard system or regularly maintaining your gutters can prevent this.
7. Insulate pipes and ductwork
Cold water pipes can produce condensation that appears as "sweating." When the air is humid and warm, the moisture will collect on the surface of the pipes, then drop down and form a puddle on the floor, creating a moldy spot. In the winter, pipes can freeze and burst, causing water to overflow and mold infestation. To prevent this, purchase pipe insulation from your local hardware store to prevent condensation and freezing.
8. Grow humidity-absorbing plants
Regulation of moisture levels will also be much easier when your indoor environment is constantly refreshed with humidity-absorbing plants. Houseplants like bamboo palms, dracaena, spider plants, and Boston ferns can absorb excess moisture to keep the air fresh and mold-free. In addition to reducing humidity levels, these indoor plants can also help improve air quality by filtering out carbon dioxide and releasing oxygen.
