5 Steps to Installing Your Mailbox

5 Steps to Installing Your Mailbox

Installing a post-mounted mailbox in front of your home is one way to add undeniable curb appeal and welcomeness to your home. This walkthrough will teach you the most common and correct way to install a mailbox in front of your home.

What you Need to Install a Mailbox

The items listed below are mandatory to complete the project to the best of its ability. If you are lacking one of these tools we would suggest not attempting to install the mailbox and instead, calling your local handyman to inquire if they can assist.

You’ll need:

  • Post-Mounted Mailbox with Post
  • Fast-Setting Concrete
  • Screwdriver (the type depends on your Mailbox)
  • Shovel
  • Level
  • Tape Measurer
  • House Numbers or Characters

Again, the above tools will be all that is required to install your mailbox into the ground. While there are other ways to install the Mailbox without concrete, this is considered the standard and proper way to ensure the longevity of your new mailbox. A concrete base will allow it to withstand harsh environments like the strong winds that can occur in Columbia.

How to Install a Post-Mounted Mailbox

1.) Dig the Hole

You can do this! — To start, you’ll only need your shovel and a tape measure. Start by ensuring that your mailbox height is no higher than 45 inches as this is the maximum height allowed within the United States Postal Service (USPS) regulations.

You’ll want to allow your mailbox to be at least six inches away from the curb to keep it safe from any potential cars or pedestrians passing by. If you’re unsure how far back you should place your mailbox from the curb, or you don’t have a curb, contact your local postmaster for additional guidance.

Note to Missouri Residents: Before you dig ANY hole be sure to call 1-800-DIG-RITE, 811 or go online to place a request to ensure there are no gas lines in the area. By law, you are required to make your locate request 3 working days before you plan to dig. Week-ends, State and Federal Holidays do not count toward the 3 working days.

2.) Embed the Mailbox Post into the Hole

There are several types of Mailbox Posts you can purchase. Federal Highway guidelines state that although your post should be stable, if struck by an automobile it should bend, brake, or fall to its side. Make sure to choose a regulation Mailbox Post from your local hardware store from one of the varying materials: wood, aluminum, or steel.

Carefully slide the mailbox post into the hole you dug in Step 1. Hold the post in place with support beams to ensure that it will not move during the process of concrete pouring we will perform in the next step. Once supported and secure measure the height of the mailbox from the ground up and double check that you are falling between the appropriate heights of 41-45 inches. It’s at this point you’ll want to use your level to make sure you’re even with the ground.

3.) Pour the Concrete and Wait for it to Set

Follow the instructions on your bag of fast-setting concrete and pour the concoction into the hole around the mailbox post. Do not overfill the hole or fill it all the way, you’ll want to leave a few extra inches worth of space below ground-level. Absolutely do not fill the concrete to be flush with the grass or dirt it resides in.

Do not remove the support beams from Step 2 until the concrete is completely set. Depending on which type of concrete you purchased, this amount of time will vary.

4.) Attach your Mailbox

You’ve made it this far — now it’s time to crown your mailbox post! Grab the manufacturer’s instructions for your Mailbox (as installation steps for these vary greatly) and follow them closely to attach. Once you have completed attaching the Mailbox you’ll want to use your level one last time to ensure that the inside of your mailbox is level with the ground below as well.

5.) Attach your Street Numbers / Characters

Add your house or street number to the front or side of the mailbox spaced evenly apart. United States Postal Service will check for uniformity and that each mailbox is clearly labeled with the correct street address number.

While nicely constructed custom mailboxes are usually fine, you’ll want to check with your local postmaster for any one-off questions. The mail is serious business no matter rain, snow, sleet, or hail!
