How to Build and Install a Sturdy Wooden Fence

Fences provide the essential architecture of a backyard, defining boundaries while offering privacy and security. A well-built fence stands straight, resists rot at the ground line, and uses the right hardware to handle wind loads and seasonal wood movement. Done well, it transforms a property and lasts for decades. Success here relies almost entirely on the layout and the post-setting process. If your posts aren't square and deep, the entire run will eventually sag or lean. Take the time to clear your lines and verify your property boundaries before digging, as moving a fence once the concrete has cured is a significant logistical headache.

Mark Your Property Lines First. Measure your fence line and drive stakes into the ground at every corner. Run a taut mason's string between the stakes to define the exact fence path, then mark post locations every 6 to 8 feet.
Dig Deep for Durability. Use a post-hole digger or auger to dig holes at least 24 to 30 inches deep, or deeper if you live in a frost-prone climate. Ensure the holes are at least three times the width of the post for sufficient concrete base.
Set Posts Perfectly Plumb. Place the posts in the holes, using a post level on two adjacent sides to ensure they are perfectly plumb. Fill the holes with concrete, sloping the top surface away from the post to shed water.
Rail Alignment Wins Straight. Measure and cut 2x4 rails to run between your posts. Attach them to the face of the posts using exterior-grade deck screws, positioning one rail near the top and one near the bottom for standard fencing.
Space Pickets With Precision. Starting at one end, nail or screw the vertical pickets to the horizontal rails using a spacer block to ensure consistent gaps. Use two fasteners per rail for each picket to prevent warping.
Seal Against Sun and Moisture. Once the wood has dried, apply a high-quality exterior wood stain or water-repellent sealer. This prevents UV damage and moisture absorption which leads to rot.
