How to Remove Deck Mold and Prevent It: Tips from LA Decks

Mold on your deck is more than just an inconvenience—it can make the surface slippery and compromise its structure over time. Keeping your deck free of mold not only preserves its beauty but also ensures safety for everyone using it. In this guide, LA Decks shares the best practices for removing mold, preventing its return, and why we recommend mold-resistant materials like tropical hardwoods (ipe, cumaru, and garapa) and composite decking.

What Causes Deck Mold on Wood Decks?

Mold thrives in damp and shaded conditions, especially when organic debris like leaves, dirt, and pollen accumulate on a deck. This moisture-laden environment creates ideal conditions for mold and mildew to grow. Many older decks or those made from traditional softwoods like cypress, pine, or redwood are particularly susceptible if they haven’t been properly maintained.

For homeowners with residential decks, regular maintenance and the choice of durable materials are key to preventing mold and ensuring long-term performance. Softwoods tend to absorb moisture more easily, making them a prime target for mold. In contrast, tropical hardwoods and composite decking are naturally more resistant, thanks to their density, natural oils, or non-porous properties.

How to Remove Mold from Your Wooden Deck

Step 1: Gather Your Supplies

To get started, you’ll need:

• A stiff-bristle brush
• A bucket of warm water
• Mild detergent or a specialized deck cleaner
• Protective gloves and eyewear
• A garden hose or pressure washer (use cautiously)

Step 2: Scrub the Mold

Mix your cleaning solution in the bucket and scrub the moldy areas with the brush. At LA Decks, we recommend avoiding harsh chemicals, as they can damage the deck material or harm the surrounding landscape.

Step 3: Rinse Thoroughly

Rinse the deck using a garden hose or a low-pressure washer to ensure all cleaning residue is removed. Proper rinsing helps prevent mold from returning.

Step 4: Let It Dry

Allow the deck to air dry in direct sunlight. This step is essential, as lingering moisture can restart the mold cycle.

How to Prevent Deck Mold from Returning

1. Clean Your Deck Regularly

Routine maintenance is the easiest way to prevent mold. Sweep away leaves, dirt, and debris, especially after rainy or windy weather. At LA Decks, we always emphasize the importance of regular upkeep to our clients.

2. Improve Drainage and Airflow

Ensure your deck is well-ventilated and not surrounded by overgrown foliage. This improves airflow and allows your deck to dry faster after rain.

3. Use a Protective Coating

Applying a high-quality sealant or stain creates a barrier that helps keep moisture out. We often recommend this step for wooden decks during our maintenance services.

Why LA Decks Recommends Tropical Hardwoods for Deck Mold Resistance

Tropical hardwoods like ipe, cumaru, and garapa are naturally mold-resistant due to their extreme density and natural oils. These woods are less porous than traditional softwoods, making it difficult for moisture and mold to penetrate.

At LA Decks, we’ve installed countless tropical hardwood decks across Los Angeles and Orange County, and they remain a top choice for homeowners seeking long-lasting, low-maintenance natural solutions. Ipe decks, for example, are renowned for their incredible durability and resistance to mold, mildew, and insects.

Composite Decking: Another Mold-Resistant Deck Option

Composite decking is a modern alternative that’s equally effective in resisting mold. Made from a blend of recycled materials, composite boards are non-porous, meaning they don’t absorb water like wood does. This makes them an excellent choice for areas prone to damp conditions.

Brands like TimberTech and Trex are frequently recommended by LA Decks for their mold resistance, low maintenance, and wide range of color options. Whether you want the look of wood without the upkeep or need a durable option for high-traffic areas, composite decking is a smart investment.
