Installing a new curb-mounted mailbox can be handy for you and the mail carrier - and add a little style to your home.
Purchase the mailbox and mounting post of your choice.
Use posthole diggers to make a narrow hole about 2 feet deep, or deep enough to meet the manufacturer's recommended mounting height.
Mix a small amount of quick-drying concrete in a wheelbarrow or large bucket. Place the mailbox's pole in the hole.
Use a scrap of lumber to cover the top of the post, and take a hammer to tap the post slightly into the ground. This will help hold the post in place as you work.
Use a level to make sure the post is straight.
Shovel small spadefuls of concrete gently and evenly into the hole until the concrete is about 6 inches below the surface.
Shovel dirt into the hole until filled. Pack loosely for now and check with the level one more time.
Wait overnight for the concrete to dry properly.
Tamp more dirt into the posthole to give your mailbox an even more secure base.
Attach the mailbox to the pole.
