One of the many benefits of composite decking is its low-maintenance qualities. However, the wood particle and plastic boards can degrade if not properly taken care of. Use this guide to preserve the health of your deck and ensure it lasts for years to come. 

How to Preserve Composite Decking

1. Prevent Mold & Mildew 

While moisture is less likely to cause composite decking to crack or rot, standing water and wet materials or structures could allow mold and mildew to grow. Avoid this by leaving at least six inches of unobstructed airflow beneath the deck to allow for adequate ventilation. Also, check the structure after heavy rainfall to ensure water is quickly draining away and not getting trapped under furniture and rugs or pooling in specific areas.

2. Clean Regularly

Composite decking is harder to stain than wood, but it's still possible if the material isn't cleaned very often. Sweep the deck at least once a week to remove debris buildup, especially between gaps. During the fall or after a windy storm, increase this frequency to prevent leaves from decomposing on the structure. Use a gentle scrub brush, water, and mild soap to remove dirt at least once a season. You could also power wash your deck, but take care to use low pressure and don't get too close to avoid splintering or scratching the material.

3. Apply a Stain

Periodically applying a water-repellent sealer will help protect your composite decking from mold and mildew growth. It will also help prevent future staining and color fading, as well as make the deck easier to clean.
