Most people prefer to keep the fence level by “stepping” the fence when running a horizontal fence over a slope. Stepping involves raising each panel between the posts as the fence moves over changes in slope, giving the fence line the appearance of stair steps. While this may be the preferred method of running a horizontal fence up a slope, there’s nothing wrong with installing your fence so it follows the undulations in the ground instead.

The lifespan of a picket fence largely depends on its material. Wooden picket fences typically last 10 to 15 years with regular maintenance, while vinyl and composite picket fences can last 20 to 30 years or more due to their resistance to weather, rot, and pests. Metal picket fences often exceed 30 years, especially when properly coated to prevent rust or corrosion.

A silt fence should be buried in a trench that is 6 to 12 inches deep. A depth of at least 6 to 8 inches is necessary to prevent water and sediment from running underneath the fence. A deeper trench, up to 12 inches, provides better anchoring during wet and windy weather. To ensure proper installation, look for a red line on the silt fence fabric, which often indicates the correct burial depth. Always adhere to local guidelines and regulations; a professional contractor will be familiar with these requirements.

The ideal spacing for four-by-four residential fence posts is usually about 6 to 8 feet between posts. However, if the fence is particularly high or you live in a very windy region, you might want to space them closer together for better stability. A fence pro can help you decide on your post spacing.
