Fences can be used to define property lines, keep animals in or out, provide privacy and act as a buffer to wind or noise--and they're often decorative as well. Fence materials can be mixed and matched to create a unique look, but deciding on the right fence for your needs can be tricky. A "living fence" can be created by using shrubs and other plants in lieu of a conventional fence.
When planning for a new fence, check to find out whether there are any covenants or restrictions in the neighborhood, and obtain a professional survey of the property before you start to build.
Chain Link
The most popular fence is chain link, and what it lacks in aesthetics, it makes up for in its relatively low cost and ease of construction. A plain chain-link fence can be dressed up by planting any number of different vines on it or plants in front of it.
Wrought Iron
Wrought-iron fences aren't cheap, but they add elegance to a property. With proper care, a wrought-iron fence can last a lifetime.
Wooden
The wooden privacy fence is extremely popular and is available in several styles. The familiar vertical picket fence looks good and makes an ideal project for do-it-yourselfers, whereas more elaborate wooden fences can be created as the budget allows and can include extensions such as cap rails and finials. Pickets can be spaced out or set solid, which provides privacy.
Although many types of wood are available, cedar lasts longer than spruce, pine or fir. Wooden fences can also be made of willow branches or other flexible tree branches. These fences blend naturally with the landscapes they surround and often reflect the personality of the gardener who built them.
When purchasing pickets, buy a dozen extras and let them weather outdoors so that when it comes time to replace a picket, the new one will match the faded color of the old one. To prevent rot, do not let pickets come in contact with the ground. Allow water to run under and away to keep insects such as termites from shortening the life of the fence.
Post and Rail
Wooden post-and-rail fences are primarily decorative and won't keep animals in or out unless lined with chain link. They are available in several styles and can be bought with two or three rails.
Stone Fences
The most expensive fence materials are stone and brick, both of which can be used to create everything from a low border fence to a towering wall. Stone fences are almost certainly the most durable and long-lasting.
