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.

A horizontal fence is typically more expensive to build than a vertical fence, often costing between 10% and 20% more. The higher cost is due to the need for a higher grade of lumber and more posts to prevent the boards from sagging, which increases both material and labor expenses. Despite the higher price, horizontal fences tend to be more durable and offer a more distinct, modern look compared to the more common vertical picket style. However, they may not be the best option for privacy, as there can be slight gaps between the horizontal rails.

Standard post spacing for shadowbox fences is 6 to 8 feet. This spacing ensures proper support for the heavy weight of overlapping pickets and prevents sagging between posts. However, areas with high winds, slopes, or unstable soil conditions may require closer spacing.

Yes, fence posts need to be installed below the frost line to ensure stability and prevent heaving caused by freezing and thawing cycles. The frost line is the depth at which soil freezes during winter. By placing posts below this line, often around 3 to 4 feet deep or as recommended for your specific region, you reduce the risk of the ground shifting, which can lead to leaning or unstable fences. Adequate depth provides better anchoring and helps maintain the fence's integrity, ensuring it remains secure and upright throughout changing seasons.
