How to Install Wooden Fencing on a Concrete Block Wall

Mark Morris

Wooden fencing is a great way to complete a landscape. It adds privacy and makes a perfect backdrop for plant material. A quality wooden fence can last upward of 20 years. Fence posts next to walls can provide challenges. Sometimes it is simpler to attach directly to the wall. Attaching wooden fences to concrete block is simply a matter of hardware. Using the right fasteners makes the attachment a simple matter. Position your last fence post less than the length of a full panel from the wall and cut your panel to fit the opening.

Step 1

Attach 6-inch L brackets to the concrete wall for each rail in your fence panel. Run a string along the top of the top fence rail to the wall. Mark the spot and use a plumb bob to locate the lower brackets directly below the top bracket. Typically, manufactured fence panels have two or three horizontal rails made of 2-by-4s. Measure the height of the rails from the ground and mark the wall at the appropriate points.

Set the first L bracket in place and mark the screw holes with a pencil. Repeat the process for all brackets.

Step 2

Use a 3/16-inch masonry bit to drill a pilot hole for every screw, typically three to four holes per bracket. Drill the hole 1/4 inch deeper than the length of the anchor. Wrap a piece of masking tape around the bit at 2 1/4 inches to mark the correct depth. Blow the dust from the hole.

Step 3

Use 1/4-inch by 2-inch tapcon type anchors to attach the brackets to the wall. Use a drill and the manufacturer-suggested screw tip. Snug the screws down firmly, but avoid overtightening.

Step 4

Attach the fence panel to the last fence post and set it against the L brackets. Use 2-inch No. 8 wood screws to attach the panel to the brackets at the wall end.
