How often should a fence be replaced?

For a wood fence, it depends a lot on the type of wood:

• An inexpensive spruce fence may last only 4 to 7 years.
• A pine fence lasts longer, about 5 to 12 years.
• Cedar lasts from 15 to 30 years, based on weather conditions and maintenance.
• A fence made of treated lumber can last 20 years or more.
