The answer to 'deck schedule' is that a well-constructed deck can last 15-25 years with proper maintenance and care. The lifespan of a deck depends on several factors, including the quality of the materials used, the climate, and how well the deck is maintained.
Pressure-treated wood is a common choice for decks as it is resistant to rot and insects. Composite and PVC decking materials can also provide a longer lifespan, often 20-30 years or more. Regular cleaning, sealing, and staining can help extend the life of a wooden deck, while composite and PVC decks require less maintenance.
