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.

The cheapest fence to install is likely to be a wire fence, whether it’s hog wire or chicken wire. Closely following that is something repurposed that would be free to collect, like a DIY pallet fence. Most wire fences are available in large quantities at a low cost, so they’re great for homes with a tight budget.

Typically, a fence requires one to two coats of stain. The exact number can vary depending on the porosity of the wood. For specific guidance, it's best to check the manufacturer's instructions. After applying the first coat and letting it dry completely, you can assess the finish. If it appears patchy, uneven, or you want a more saturated color, a second coat is recommended. An extra coat can also help cover lap marks.

Both nails and screws are common in fence construction, including on pickets. Some builders prefer to use nails when connecting the pickets to the rails and screws when connecting the rails to the posts. However, the best option usually depends on the type of wood fencing and the variety of wood you choose.
