Top 5 Mistakes to Avoid When Caring for Your Composite Deck in the Heat

A composite deck is the perfect place to soak up the summer sun, enjoy backyard barbecues, and unwind with family and friends. But while these decks are known for being low maintenance, they still need a little summer love to stay looking their best. Here are the top five mistakes homeowners make when caring for their composite deck during the hottest months... and how you can avoid them.

1. Skipping Regular Cleaning

Many people think composite decking doesn’t need much upkeep, but dirt, pollen, and spilled drinks can build up fast in summer. If ignored, these can lead to staining and mildew. Gently sweeping and rinsing your deck every few weeks keeps it fresh and helps prevent grime from settling in.

2. Using Harsh Cleaners

It’s tempting to grab the strongest cleaner you can find, especially when facing stubborn spots. However, bleach and harsh chemicals can damage the protective finish of composite boards, leaving them faded or discolored. Stick to mild soap and water or a cleaner specifically designed for composite decking.

3. Ignoring Shade and Furniture Protection

Direct sunlight can heat up your deck boards and fade their color over time. Using outdoor rugs or strategically placing umbrellas can help protect both your deck and your feet from scorching surfaces. Also, consider using furniture pads or glides to prevent scratches when moving chairs and tables.

4. Overdoing It with a Pressure Washer

A pressure washer can be handy, but using it incorrectly is one of the quickest ways to ruin your deck. Too much pressure can gouge or peel the surface of composite boards. If you must use one, keep the setting below 1,500 psi and hold the nozzle at least a foot away from the surface.

5. Forgetting About Mold and Mildew Prevention

Even though composite decks resist rot, they’re not completely immune to mold, especially in humid climates. Keep nearby trees and bushes trimmed to improve airflow and minimize debris. Regular cleaning and allowing your deck to dry completely after rain are key steps in preventing unwanted growth.

Care for your composite decking!

With a bit of attention and the right care, your composite deck can stay cool, clean, and ready for every summer gathering. Avoiding these mistakes will help extend its life, keep it looking sharp, and ensure it remains a favorite spot for years to come.
