In 1914, Robert Frost wrote, in his poem Mending Wall, "Good fences make good neighbors." You may choose to build a privacy fence on your property for any number of reasons: to increase safety, privacy or security; enclose pets or children; eliminate sight lines beyond your property; or simply to enhance your home's curb appeal. Once you gain an understanding of the materials required as well as layout and installation techniques, building a wood privacy fence is a job many do-it-yourselfers can accomplish.
