A metal fence can be a great way to protect your home and your family members as well as to improve its look. It can also act as a security deterrent from burglars, prevent pests or animals from entering a garden, offer a safe area for children, and clearly define the borders of a property. For this example, we’ll consider the cost of installing a standard 4’ tall fence depending the material used: aluminium, steel or wrought iron. This project averages $2000~$2500.
