Composite Deck Facts | Best Pick Reports
Most composite decks are composed of a treated lumber substructure, over which are wood and plastic resin surfacing boards and trims. This combination creates a deck that is low-maintenance, durable, and highly resistant to rotting and insects.
Composite considerations. While composite decking will not require staining and is unlikely to crack or split, its appearance will fade over time. Composite deck surfaces are also susceptible to mold and mildew. If you discover mold or mildew on your composite deck, you can remove it with a mixture of equal parts of bleach and water. Be careful when working with bleach, as it might harm any plants that it comes into contact with. You should also try to find the source of the moisture that caused the problem. This could be a sprinkler, a potted plant, an air conditioner, or simply standing water left over from a rainstorm.
A popular choice for busy homeowners, the only upkeep that’s required by a composite deck is a periodic sweeping and washing of its waterproof surface. Composite decks are generally more expensive to purchase and install, but they’re likely to make up the difference in their durability and minimal maintenance costs.
