i am building a privacy fence but i am unsure how to attach it to the house. it is a brick house with 6 foot sidewalk around it. i need a way to attach the 4x4 post to the brick on the house so that it will be stable.
Three 1/4" galvanized lagbolts 5" long with lead anchors. Top, bottom and middle. Be sure to anchor into the brick, not the mortar, and fill each hole with silicone caulk before you install the anchors.
Predrill the holes in the post so that the lag goes cleanly through and use galvanized washers to hold the post into place. If you wanted to you could recess the lags by drilling a hole with a spade bit (before you drill the hole for the lag) the same size as the washer about 3/4" in.
