Preventing mildew recurrence on your siding requires a combination of regular maintenance and proactive measures to control moisture and inhibit mildew growth. Here are some steps you can take to stop mildew from coming back on your siding:

1. Clean Your Siding Regularly:

• Mildew thrives on dirt, dust, and organic matter that accumulate on the surface of your siding. Regularly clean your siding to remove these materials and prevent mildew growth.
• Use a mixture of mild detergent or dish soap and water to wash the siding surface thoroughly. You can also use a pressure washer on a low setting, but be cautious not to damage the siding or force water behind it.

2. Improve Air Circulation:

• Poor air circulation can contribute to moisture buildup on your siding, creating an ideal environment for mildew growth. Trim back any vegetation or landscaping that may be blocking airflow around your home.
• Ensure that vents, soffits, and other ventilation openings are clear and functioning properly to allow air to circulate freely around your home and under the siding.

3. Address Water Drainage Issues:

• Water pooling or draining toward your siding can contribute to moisture buildup and mildew growth. Ensure that gutters and downspouts are clear and directing water away from the house.
• Grade the soil around your home to slope away from the foundation, preventing water from pooling near the siding. Consider installing a French drain or other drainage solutions if necessary.

4. Seal and Repair Siding:

• Inspect your siding regularly for signs of damage, such as cracks, gaps, or holes, where moisture can penetrate and lead to mildew growth. Seal any openings with caulk or appropriate sealant to prevent water infiltration.
• Replace damaged or deteriorated siding panels as needed to maintain the integrity of your siding system and prevent moisture-related issues.

5. Apply Mildew Inhibitors:

• Consider applying a mildew-resistant treatment or coating to your siding to inhibit mildew growth. These products contain ingredients that discourage mildew formation and help protect your siding against future infestations.
• Follow the manufacturer’s instructions carefully when applying mildew inhibitors, and reapply as needed according to the product recommendations.

6. Maintain Landscaping:

• Trim back trees, shrubs, and other vegetation near your home to reduce shade and moisture retention on the siding. Prune overhanging branches to allow sunlight and airflow to reach the siding surface.
• Avoid planting dense vegetation directly against the house, as this can trap moisture and create an environment conducive to mildew growth.

7. Monitor Humidity Levels:

• Keep indoor humidity levels in check to prevent moisture from accumulating on your siding. Use dehumidifiers in damp areas of your home, such as basements or crawl spaces, to reduce humidity levels and discourage mildew growth.

By following these steps and implementing proactive measures to control moisture and inhibit mildew growth, you can effectively stop mildew recurrence on your siding and keep your home looking clean and well-maintained. Regular maintenance and vigilance are key to preventing mildew from coming back and preserving the integrity of your siding for years to come.
