Are deck storage boxes waterproof?
Since the typical deck box sits outdoors through all types of weather, most are treated for resistance to damage caused by moisture and UV radiation. But note that most deck boxes don’t claim to be entirely waterproof; they are water-resistant. When treated and sealed properly, wood deck boxes can be durable and last for years. However, if not maintained, wood can fade over time and be susceptible to damage from water or pests.
