The average lifespan of a wood fence is 15 to 20 years, but some can last for 40 years or more depending on several factors. The type of wood is crucial; for example, untreated pine may only last 5 to 10 years, while pressure-treated pine can last up to 20 years, and cedar's natural resistance can extend its life to 40 years. Other factors include local weather conditions, with wet and windy climates causing faster deterioration, and the quality of maintenance. Higher-end wood, metal posts, and privacy fence styles also tend to last longer.

Green branches are more flexible and easier to work with, but they'll shrink as they dry, which can loosen your fence weave over time—so you'll need to weave them extra tight to account for shrinkage. Some species, particularly willow, may also try to sprout when used green. For these reasons, it’s typically easiest to use branches that have dried for a week or two.

In most states, it is a legal requirement to have a fence around your pool to protect both swimmers and pool owners. These laws can vary by state, city, and county, so you must research the specific regulations in your area before installation. The rules may also differ for inground versus above-ground pools, with inground pools typically requiring a full fence. Additionally, most homeowners' insurance providers will require a fence around a residential pool before providing coverage. As a general rule, it's always best to have a fence for everyone's safety.

A high-quality wrought iron fence is one of the most durable options available and can last a lifetime, or even centuries, with proper care. However, wrought iron is susceptible to rust and corrosion if not maintained.

To maximize its lifespan, regular maintenance is required. This includes:

• Cleaning the fence with soapy water every six months.

• Scrubbing away any rust or corrosion as soon as it appears.

• Applying a new coat of paint or refinishing the fence every few years to protect the metal from moisture and oxygen. The recommended frequency varies, with sources suggesting anywhere from every 1 to 10 years.

If significant rust develops, it's wise to hire a professional fence repair company to clean the rust and reseal the fence. The cost to refinish a fence is typically between $5 and $12 per square foot, a worthwhile investment to ensure its longevity.
