A neighbor's fence is their property, and altering it without their consent could constitute trespassing or property damage, which may have legal consequences.

A wrought iron fence is generally considered a worthwhile investment, provided the cost fits your budget and its characteristics meet your needs. While it is an expensive material, its exceptional durability and longevity mean you can save money over time by not having to replace it.

Key benefits include:

• Durability and Security: Wrought iron is strong and provides excellent security for your home.

• Longevity: With proper maintenance, it can last a lifetime or longer.

• Aesthetics: It offers a classy, timeless, and elegant look that can boost your home's curb appeal and property value, especially when complementing brick or stone architecture.

However, it's important to note that wrought iron fencing does not offer much privacy. If professionally installed and maintained, it is a sound long-term investment.
