Common Mistakes And Misconceptions

Mistake/Misconception Correct Viewpoint
Composite decking is completely mold-resistant. While composite decking is more resistant to mold than traditional wood decking, it is not completely immune to mold growth. Proper maintenance and cleaning are still necessary to prevent mold growth.
Only poorly maintained decks get moldy. Even well-maintained composite decks can develop mold if they are exposed to moisture for extended periods of time or in humid climates. Regular cleaning and preventative measures should be taken regardless of the deck’s condition.
Bleach is the best solution for removing deck mold. While bleach may effectively remove surface-level mold, it can also damage the protective coating on composite decking and harm nearby plants and wildlife. It’s better to use a specialized cleaner designed specifically for composite decking that won’t cause any damage or harm surrounding areas.
Power washing will always remove all traces of deck mold. Power washing can be effective at removing surface-level dirt and grime but may not fully eliminate deep-seated molds that have penetrated into the material fibers of your deck boards‘ surfaces.
Mold only grows on horizontal surfaces like decks. Mold spores can grow anywhere there is moisture present, including vertical surfaces such as railings or walls near your deck area.
