Vinyl is nonporous, so if your fence ever gets surface dirt or debris, just wash it away easily with a periodic spraying from a garden hose. Occasionally algae, mold, or mildew will start to grow on your plastic fence, especially if the fence sits near a sprinkler that keeps the area damp. But it’s typically not difficult to clean off this staining. A plastic fence is also a safe choice for families and pet owners. Unlike wood fences, which are often treated with chemicals to protect the fence from weathering, vinyl is non-toxic. It doesn’t splinter and contains no nails or sharp edges that can harm children or animals. Plastic is also an environmentally friendly fence material, since it is fully recyclable and offers an eco-conscious alternative to the dwindling supply of trees harvested for wood fencing.
