According to North American Deck and Railing Association (NADRA) there are more than 60 million decks in the U.S. (50m residential and 10m commercial). It is estimated that 30 million decks are past their useful life and need to be replaced or repaired. It is crucial for homeowners to have their decks inspected to verify the integrity of their deck to ensure user safety as well as help extend the deck’s lifespan, improve appearance, and increase livability.
