Find top rated wood fence installers in your area

To find how much fencing you need, it’s best to contact a pro. To do it yourself, you’ll need to determine code restrictions on height and post spacing and measure property and utility lines. Then, measure the distance of where the fence will go and divide it by your post spacing. Add two to this number to determine how many posts you need. Then multiply that figure by two or three (for rails) and divide the total length of fencing by the width of each picket you use to calculate the amount of wood needed.

Wood fences can last about 15 to 20 years, depending on the type of wood, weather conditions, and level of maintenance. Pine is one of the most popular choices for wood fences and lasts around 10 to 15 years. Composite fences last even longer, typically 20 to 30 years or more.

To prolong the life of your wood fence and keep it in peak condition, make sure to inspect it annually, looking for loose nails, screws, rotting boards, and rusting gate hinges. Apply fresh paint or stain every two to three years, and be sure to clean the fence regularly.

Fence posts are typically placed four to eight feet apart. But you’ll need to check with your local code requirements to ensure the correct spacing, depth, and setting. In addition, the placement of your fence posts depends on the fence height and material. Generally speaking, it’s better for the fence if your posts are closer together.

To avoid upheavals or other issues, bury your fence post so the depth exceeds the frost line, or about one-third to one-half of the aboveground height of your post. But, like with the placement of the fence post, check with your local code requirements to determine the right depth for your home since it varies by location.
