On most untreated wood fences, there is no need to sand before treating. You typically only need to sand if there’s an old coat of paint or stain on your fence. If you do need to sand off a previous paint or protective coating (like an old stain or sealant), use medium-grit sandpaper.

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.

There are many types of wood fencing that you can choose from. For split rail fencing, the most common wood types are cedar, pine, black locust, and chestnut. The best wood for you will depend on if you like the way a certain wood looks and the availability of the wood type in your area.

Most of the wood types you can find at your local home improvement store are good choices since they all have rot-resistant properties or are pressure-treated with pesticides. If none of the wood options speak to the look you’re going for, check out vinyl fencing.

A board on board fence is more expensive than other types of privacy fences. That’s because these fences require overlapping boards, which drives up material and labor costs. On average, a board on board fence costs 30% more than an average wood fence.
