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.

You can only change your neighbor's fence with their permission. A neighbor's fence is their property, and altering it without their consent could constitute trespassing or property damage, which may have legal consequences. If you have concerns or disagreements about your neighbor's fence, communicate with them openly and try to reach a mutually agreeable solution. If you believe the fence violates local zoning laws or property regulations, consult with local authorities or seek legal advice to address the issue through proper channels. 

Ideally, your concrete should set slightly above ground at an angle sloping away from the fence post. This will add extra support and allow water to run away from the wood fence post. Keeping water out will help prevent wood rot. Additionally, you can add soil on top of the concrete for a seamless finish. 

The bottom strand should sit between 12 to 15 inches from the ground. If you have a problem with small critters, you can aim for 8 inches. Three-strand fences should be 16 to 19 inches apart, four-strand fences should be 10 to 12 inches apart, and five-strand fences should be 8 and 10 inches apart.
