That depends on the quality of the wood, how well it's treated, and how much it's used. A high-quality wood fence might last for 10 or 20 years before needing to be replaced, while a lower-quality fence might only last for 3 or 4 years.

It depends on the weather, the type of wood, and how well it's been treated. In general, a wood fence should last anywhere from 5 to 15 years. If you live in a hot, dry climate, your fence may need to be replaced more often because the extreme weather will cause the wood to dry out and crack. If you live in a humid climate, your fence may last longer because the humidity will help keep the wood from drying out. The type of wood also makes a difference. Cedar is a naturally rot-resistant wood and will last longer than pine or fir. And if you treat your fence with a sealant or stain, it will protect the wood from the elements and help extend its life
