How to Prevent Mold and Mildew on Your Deck or Fence

Power Washer

Keeping your deck and fence clean is key to preserving their appearance and longevity, but Atlanta’s warm, humid climate can make this challenging. Mold and mildew often thrive in these conditions, turning once-beautiful wood gray, slimy, and potentially unsafe. Here’s how to keep your outdoor spaces mold-free—and why professional deck and fence cleaning can make all the difference.

1. Clean Your Deck and Fence Regularly

Regularly cleaning your deck and fence can prevent mold and mildew buildup. Remove leaves, dirt, and other debris that hold moisture and foster mold growth. While a garden hose can rinse off surface debris, a professional pressure washing service is much more effective at removing the dirt and mildew hidden deep in the wood grain.

2. Apply a Mold-Resistant Sealant

Sealing your wood surfaces is one of the best defenses against moisture. A quality mold-resistant sealant creates a barrier that reduces mold growth, keeping your deck and fence in top shape. However, sealants are most effective when applied to clean wood, so a professional cleaning beforehand is essential.

3. Improve Sun Exposure and Air Circulation

Mold thrives in dark, damp conditions. Trim back plants or trees that create excessive shade, and ensure your deck and fence have enough air circulation. These steps help reduce the moisture that mold needs to grow.
