Why Composite Deck Maintenance Matters

Even though composite decking resists rot, warping, and insect damage, Long Island weather can still affect your deck:

  • Moisture and Humidity: Can lead to mold or mildew on the surface

  • Salt Air: Corrosive for fasteners and can discolor certain materials

  • Sun Exposure: UV rays can slightly fade or discolor decking over time

  • Falling Debris: Leaves, pine needles, and dirt can trap moisture

Routine maintenance ensures your composite deck stays attractive, safe, and functional year-round.


Essential Composite Deck Maintenance Tips

1. Regular Cleaning

  • Sweep your deck weekly to remove leaves, dirt, and debris

  • Wash the surface with a mild soap or composite deck cleaner every few months

  • Use a soft brush or broom; avoid wire brushes or high-pressure washers that can damage the surface

2. Remove Stains Promptly

  • Spills from food, drinks, or plant material can stain the surface if left too long

  • Clean stains quickly with water and a mild detergent

  • For tougher stains, use a composite deck-approved cleaner

3. Prevent Mold and Mildew

  • Ensure proper airflow under and around your deck

  • Trim back shrubs or plants that trap moisture

  • Use a solution of water and vinegar or a commercial composite-safe mold remover for affected areas

4. Inspect Fasteners and Railings

  • Check for loose screws, bolts, or railings periodically

  • Replace corroded fasteners with stainless steel or composite-approved hardware

5. Protect From Heavy Furniture

  • Use protective pads under furniture legs to prevent scratches or gouges

  • Avoid dragging heavy objects across the deck surface

6. Seasonal Maintenance

  • In winter, remove snow using a plastic shovel to avoid scratching

  • Avoid using salt or chemical ice melts that may damage the surface

  • Rinse deck in spring to remove winter salt residue
