Mailbox installation in Baltimore may sound like an expensive project, but it is not. The cost of installing a mailbox is usually affected by the materials that will be used, the labor cost, and the design. There are many materials that can be used for a quality Baltimore mailbox installation. Although wood is an affordable choice, it is not commonly used because it tends to deteriorate faster when exposed to harmful elements and changing weather conditions. Steel or metal are the most popular materials. Although initial installation can be a bit expensive, it will pay off for itself in the long run. Steel and metal are durable and can withstand years of heavy exposure to harmful elements and extreme weather conditions. Depending on the design, a mailbox installation in Baltimore is estimated to be around $150 to $800.
