The cheapest farm fences are typically wire fences, which cost less to install than traditional lumber fences. Barbed wire is one of the most inexpensive options due to its simple materials, making it a good choice for low budgets. It is suitable for confining docile animals in large spaces, as it provides a visual barrier and a mild deterrent. Other options like hog wire and woven wire fences are also cost-effective because they require less lumber than a full wooden fence. These types of wire fences are strong, long-lasting, and relatively easy to repair, though they are often considered less aesthetically pleasing than wood.

A fence gate can sag for several reasons. The issue often stems from the hardware, such as damaged or bent hinges, or loose screws that can no longer support the gate's weight. The gate frame itself might also have come out of square due to failing supports. Alternatively, the problem may not be the gate but the supporting fence post, which could be leaning or out of place. In many cases, fixing a sagging gate is as simple as tightening the hinge screws or upgrading to more robust hinges.

A bamboo fence can last up to 20 years when properly installed and maintained. Bamboo is a durable material, but to get the most life out of it, you should clean and seal the fence every few years. Staining the bamboo can also restore the appearance if the color fades over time. Use screws to fasten the bamboo, rather than twine, to ensure the bamboo fence stays together longer.

When considering how much of a gap should be under a fence or gate, a good rule of thumb is to keep gaps between 2 and 5 inches tall. This allows for some ground clearance for the gate but still provides safety for children and pets, who shouldn’t be able to squeeze through a gap of that size.
