If your house was built since the mid 1990s, there is a chance that the floor system is constructed with a MWJ (Manufactured Wood Joist) floor system. Deck surfaces exposed to direct sun and rain take a terrific beating. They’ll hold decay at bay until water slowly leaches these chemicals out of the wood. The result is a shabby deck.
