Wood composite decking is an increasingly popular choice for homeowners seeking a low-maintenance, durable, and attractive outdoor living space. Despite its reputation for minimal upkeep, there are still some essential steps to ensure your composite decking stays in excellent condition and retains its aesthetic appeal for years to come. In this blog, we will discuss how often you need to clean or maintain composite decking, how to clean it, how to maintain it, and how to maximize its life span.


How Often Do You Need to Clean or Maintain Composite Decking?

The frequency of cleaning or maintaining your composite decking depends on several factors, such as the amount of foot traffic, the surrounding environment, and your personal preferences. As a general rule, it’s a good idea to clean your composite deck at least once a week with a brush and water. This will help remove dirt, debris, and any organic material that may have accumulated, reducing the risk of mould, mildew, or algae growth. If you live in an area with heavy tree coverage or experience frequent storms, you may need to clean your deck more often to prevent staining or damage.


How to Clean Composite Decking

  • Sweep Regularly: Regularly sweeping your composite deck with a soft-bristle broom will help remove dirt, debris, and leaves that can accumulate on the surface. This will not only keep your deck looking clean but will also prevent the growth of mould and mildew.
  • Wash with Soap and Water: For general cleaning, mix a mild dish soap with water and use a soft-bristle brush or mop to scrub the surface of your composite deck. Rinse thoroughly with a garden hose to remove any soap residue.
  • Tackle Stains: For stubborn stains, such as grease or oil, use a composite deck cleaner specifically designed for your decking material. Follow the manufacturer’s instructions for the best results. Avoid using harsh chemicals or abrasive cleaning tools, as these can damage the surface of your composite decking.
  • Remove Mold and Mildew: If you notice mould or mildew on your composite deck, use a specialized cleaner that is safe for composite materials. Ensure that the cleaner you use is compatible with your specific decking product. 


How to Maintain Composite Decking

  • Inspect Regularly: Periodically inspect your composite deck for any signs of damage, such as loose boards, damaged fasteners, or areas of excessive wear. Address any issues promptly to prevent further damage.
  • Manage Vegetation: Keep trees, shrubs, and other vegetation trimmed back from your composite deck to prevent debris accumulation and promote proper airflow.
  • Proper Ventilation: Ensure there is adequate ventilation underneath and around your composite deck to prevent moisture buildup, which can lead to mould and mildew growth.
  • Redirect Downspouts: Make sure your home’s gutter downspouts are directed away from your composite deck to minimize the amount of water that pools onto the decking surface.
  • Avoid Excessive Weight: Be mindful of the weight of outdoor furniture, planters, and other items placed on your composite deck, as excessive weight can cause damage to the decking material.


Maximizing the Life Span of Your Composite Decking


  • Follow Manufacturer’s Guidelines: Always follow the manufacturer’s guidelines for installation, cleaning, and maintenance to ensure the longevity of your composite decking.
  • Protect from Direct Sunlight: If possible, consider installing a pergola, awning, or shade sail to protect your composite deck from direct sunlight. Prolonged exposure to UV rays will cause the colour of your deck to fade over time but will have no adverse effect on its performance. 
  • Use Protective Mats: Place protective mats or rugs under outdoor furniture, grills, and planters to prevent scratches, stains, and other damage to your composite decking. Be sure to choose mats that are breathable and won’t trap moisture beneath them.
  • Regular Maintenance: Keep up with regular cleaning and maintenance tasks to prevent small issues from becoming more significant problems. By staying proactive, you’ll help extend the life of your composite decking.
  • Promptly Address Repairs: If you notice any damage to your composite deck, such as a cracked or warped board, address the issue promptly to prevent further damage or potential safety hazards.
