Ideally, your concrete should set slightly above ground at an angle sloping away from the fence post. This will add extra support and allow water to run away from the wood fence post. Keeping water out will help prevent wood rot. Additionally, you can add soil on top of the concrete for a seamless finish. 

How much does a privacy fence cost? Stockade fences cost $12 to $13 per linear foot for materials. You may find fencing that costs less, but it’s likely wholesale wood manufactured using young trees. Fencing materials made with young trees are less durable than those made with mature trees.

For installation, expect to pay $30 to $80 per hour. Installing a 150- to 200-linear-foot fence takes 20 to 35 hours, which comes to about $600 to $2,800 for labor.

Since wood is weaker when installed horizontally versus vertically, a horizontal fence is prone to sagging. You can prevent this drooping from happening by building a sturdier fence. Use softwoods that are more stable, such as cedar and redwood, or denser hardwoods for your fence materials. If you can’t afford these pricey materials, use thicker two-by-six pressure-treated pine boards or shorten the span the fence boards have to cover by installing more posts.

How long a wood fence lasts depends on the type of wood and its style. The design of a shadow box fence makes it more durable than other fence types because the alternating pickets disperse the weight across the rails. As a result, you won’t have to worry as much about sagging or failing pickets. However, remember that the hollow design of a shadow box fence makes it more difficult to apply the sealer, which is crucial to extending its life.
