Pickets should sit at least 2 inches off the ground to encourage groundwater to flow underneath. Pickets can sit as much as 6 inches off the ground, but setting it any higher could let pets in or out of your yard unintentionally. These are not to be confused with the fence posts anchored underground with soil or concrete footing.

The lifespan of a fence can range from 5 to 50 years, depending heavily on the material, local climate, and how well it is maintained. For example, a wooden fence might last 7 to 15 years, while a vinyl fence typically lasts 20 to 30 years. Metal, composite, and glass fences have some of the longest lifespans. Proper maintenance, such as regular cleaning, inspections, and staining or sealing for wood, is key to extending the life of any fence material. Vinyl and composite are durable options that don't require sealing.

Who pays for a new fence between neighbors depends on its location relative to the property line. If you build the fence entirely on your property, you are solely responsible for the costs of installation, maintenance, and repair. If the fence is built directly on the property line, both neighbors are typically responsible for the costs. In this case, it is essential to consult with your neighbor beforehand to agree on a plan for payment. While you should always inform your neighbor of your plans in advance, you generally cannot force them to contribute financially unless there are specific local laws, such as in California, where both parties might be responsible for costs unless a different agreement exists. It's a good idea to get a property line survey to know the exact boundaries before building.

A chain link fence typically lasts between 15 and 20 years, but with proper maintenance, it can last for 30 years or more. To preserve the fence, it's important to keep the mesh wire tight, which can be done with a come-along tool every 6 to 12 months. Investing in a fence with a galvanized, powder-coated, or vinyl-coated finish can increase its lifespan to 20 to 30 years and reduce maintenance needs, as these coatings provide extra protection against the elements.
