How to install a wood fence on top of concrete

There are many reasons to build a wood fence. Among them are aesthetics, privacy, durability and cost. Fences keep people out of your yard while keeping children and dogs in. You can have a wood fence of just about any design, and wood tends to make everything look great. A wood fence typically is built in the ground, but you also can attach it to a concrete wall.

Saturate the bottom one-third of each post with wood preserver and let the posts sit overnight.

Decide where to put the fence. Mark off the area with cones, starting at the corners and then spacing them 1.8 to 2.4 m (6 to 8 feet) apart.

Verify that each socket with baseplate is level and even. If it isn't, old pieces of roofing slate will work to level it. Secure each to the concrete wall. Do this by positioning and drilling the fixing holes using a sharp masonry bit and a hammer action electric drill. Then bolt it into place.

Secure each fence post in the sockets with bolts. Verify that each is level and in line with the previous fence post.

Install a top rail and a bottom rail between each set of 2 fence posts. The bottom rail should be 5 cm (2 inches) off the ground to make it easier for trimming the grass as well as preventing rot.

Attach the fence boards to the top and bottom rails. For a basic privacy fence with vertical boards, screw or nail each board into place with only a small gap between boards, starting at one end and working your way around the entire length.


Know where your property line is before you install a new fence. Call your local government to see if permits are required and to learn any local codes. Cedar is a great for fences because, unlike most other raw woods, it doesn't need to be treated.
