Composite Decking Maintenance: Expert Tips from LA Decks

Composite decking is a popular choice for homeowners across Los Angeles and Orange County, thanks to its durability, modern style, and low maintenance requirements. While composite decks from top brands like TimberTech, Trex, and Deckorators are designed to be nearly maintenance-free, regular care is essential to keep them looking their best.

With over 20 years of hands-on experience, LA Decks has become a trusted name for installing and maintaining composite decks. As a certified TimberTech Pro, we’re dedicated to helping homeowners preserve their decks and fully enjoy their outdoor spaces for the long haul.

Why Composite Decking Maintenance Matters

Composite decks are a smart investment, designed to resist rot, splintering, and warping while offering lasting beauty and functionality. But even the toughest materials benefit from a little care. Routine cleaning not only keeps your deck looking fresh but also prevents debris and stains from dulling its surface or causing unnecessary wear over time.

What sets composite decking apart is its low-maintenance nature—there’s no need for deck staining or sealing like traditional wood requires.

However, giving it some attention with the right tools and techniques ensures it remains a striking focal point in your outdoor space. Whether you’re hosting in Los Angeles, enjoying the coastal breeze in Newport Beach, or relaxing in the heart of Orange County, a well-maintained deck makes all the difference.

Tools You’ll Need for Composite Deck Maintenance

Before starting, gather these tools:

• A broom or leaf blower for removing debris
• A garden hose or power washer (keep pressure under 1,500 PSI)
• Mild dish soap or a composite deck cleaner
• A soft-bristled deck brush or sponge mop
• Microfiber towels for drying

Every composite decking brand comes with its own care and maintenance guidelines to ensure the longevity of its products. While the steps outlined here provide a general approach, it’s smart to refer to your specific brand’s website or care manual for the most accurate instructions. Whether your deck is from TimberTech, Trex, Deckorators, or another manufacturer, following their recommendations will help you avoid damage and maintain the quality of your outdoor space.

Step-by-Step Composite Deck Cleaning

1. Clear the Deck

Start by removing furniture, planters, and other items to access the entire surface. Sweep away leaves and dirt using a broom or leaf blower. This step is especially important in areas like Laguna Beach or Malibu, where sand and salt can accumulate.

2. Rinse Thoroughly

Using a garden hose or power washer (under 1,500 PSI), rinse the deck to remove loose dirt and prepare the surface for cleaning. Work in sections, starting from one end of the deck and moving systematically to avoid missing spots.

3. Scrub Gently

Mix warm water with a mild dish soap or a composite deck cleaner, such as TimberTech’s DeckCleaner. Using a soft-bristled brush, scrub the deck in the direction of the grain to lift dirt and stains. Avoid harsh scrubbers, as they can damage the finish.

For stubborn spots, let the cleaner sit for a minute before scrubbing again. Focus on high-traffic areas and corners, as these tend to collect the most grime.

4. Spot-Treat Stains

Accidental spills happen, especially during backyard gatherings. Address stains from grease, wine, or other substances promptly. Blot the area with a paper towel, then clean it with soapy water or a specialized cleaner designed for composite decking.

5. Rinse and Dry

After scrubbing, rinse the entire deck thoroughly to remove soap residue. Use towels or a sponge mop to soak up standing water, preventing streaks or water spots. Allow the deck to air dry completely before placing furniture back on it.

Seasonal Maintenance Tips

Regular Sweeping

Regular sweeping removes debris like leaves and dirt, which can cause stains or mold growth. In areas like Pasadena or Tustin, where pollen is common, frequent cleaning helps keep your deck looking fresh.

Prevent Mold and Mildew

While composite materials are resistant to mold, damp conditions can still lead to growth. Use a mild cleaner to address any spots as they appear, especially in shaded or humid areas.

Protect Your Deck

Use protective mats under grills and outdoor furniture to prevent scratches or stains. For areas exposed to salt air, like Manhattan Beach, rinse your deck regularly to minimize salt buildup.

Schedule Deep Cleaning

Plan a thorough cleaning at least twice a year—once in the spring and again in the fall. This ensures your deck is ready for summer gatherings or to withstand Southern California’s version of winter.
