8 Easy Steps to Install a Post-Mount Mailbox

1. Dig the Ground

You begin the project by digging a hole into the ground. However, remember that according to the guidelines of USPS, a post-mount mailbox cannot be taller than 45 inches off the street. Hence, you will have to dig accordingly. If your street has a curb, it would add a few inches more to the height. Your mailbox should ideally be about 6-7 inches behind the curb. You can also take the help of your postmaster to mark the ideal spot on the ground.

2. Add Gravel

Add Gravel

Adding gravel or small stones at the bottom of the pit is an extra step we recommend to ensure proper drainage. It is advisable to add 4 inches of gravel which should leave you with a pit of 16 inches. This way, your post will be secure strongly and will also comply with the regulations. As we mentioned, this is an added precaution, and you can choose to skip this step and move ahead.

3. Insert the Post

Attach the Box

The next step is to insert the post into the ground. Avoid using metal or concrete posts that won’t bend or fall to the side if hit. Instead, go for basic wooden or aluminum posts. Once you insert it, prop it up with the help of support beams. Also, remember to measure its height and ensure it is level with the ground. It is advisable not to insert the post deeper than 24 inches but at least 20 inches deep.

4. Add the Cement

Add the Cement

A pivotal step in installing a mailbox is pouring the cement. It must be mixed adequately, should be a strong adhesive, and must be added in appropriate quantities. You shouldn’t fill in the concrete till ground level. Leave a couple of inches at the top. Check the level of the post again concerning the ground once you add it. If it has moved even slightly, ensure that you shift it back before the cement starts drying.

5. Let It Set

Let It Set

Give enough time for the concrete to set. This duration typically depends on the type of cement you use. You can check the concrete label for the exact details. One thing to remember is to leave your supporting beams until you are absolutely sure that the cement has set completely. Use extra timbers on the sides for added stability. Usually, it takes a minimum of four to five hours for the cement to dry.

6. Top It with Soil

Top It with Soil

As we suggested in step 4, avoid filling the entire pit with cement till the ground level. The last couple of inches you left should be filled with soil and dirt. This way, your ground won’t have a small circle of cement and can blend again with the garden soil. Once you flatten the dirt, you can plant grass on it to ensure it goes with your theme.

7. Attach the Box

Attach the Box

One of the final steps of installing a mailbox is to mount and attach the box. The manufacturers of a mailbox usually provide a set of easy instructions that you can follow to install it on the post. Ensure that you secure it with nails and screws. Before you end your project, cross-check if you comply with all the USPS regulations and follow the rules to avoid tardy charges.

8. Paint Your House Number

According to the rules of USPS, to avoid any confusion, every mailbox should be designated with the appropriate house number. If your mailbox happens to be at the end of the street or on a different street altogether, you must put the complete street name on it as well. Also, your house/street number should be at least one inch long. After painting the address, the final step of installing a mailbox is complete.

4 Easy Steps to Install a Wall-Mount Mailbox

1. Mark the Measurements

Mark the Measurements

The first step in installing a mailbox that is mounted on the wall is to take the right measurements. Select a spot on the wall that is easily accessible by the postman. You don’t want your mailbox such that the person who delivers the mail or couriers cannot find it at all. Also, ensure that it is even when you hold the mailbox flat to the wall.

2. Drill Into the Wall

Drill Into the Wall

Once you have your proper measurements, drill into the wall on the marks you made. In most cases, a very deep hole isn’t required for installing a mailbox on the wall. You can use basic drills for brick or masonry walls. However, it is always advisable to check the instructions provided with the mailbox so that it is stable enough and will stay mounted.

3. Insert the Hardware

Insert the Hardware

Mounting shelves or racks on the wall typically needs mounting hardware. Install plastic anchors into the wall to properly secure your mailbox on the wall. If your mailbox is lightweight and designed for letters and similar official mail, it may not require additional mounting hardware. The best way is to check the instructions and ensure you’re carrying out the process appropriately.

4. Mount It on The Wall

Mount It on The Wall

You are now one step away from completely installing a mailbox on your wall. Once you’ve secured the nails or mounting hardware, hang the mailbox on the wall. Ensure that it is hung on an even level horizontally. We advise you to drill the screws halfway first and keep checking the levels before you drill them all the way. This is because redoing the entire project is certainly an unwanted hassle.
