What Materials Do I Need to Build a Brick Mailbox?
A durable, stable mailbox must be built in compliance with local and USPS regulations to be used as an official mailbox for your home. It is important that you have the right tools, materials, and safety gear for this type of home improvement project. When you are building a DIY brick mailbox, Batchelder is a one-stop shop for all the materials you will need to build a great-looking mailbox for your home.
Tools & Supplies
The right tools and safety gear will make building an outdoor mailbox more efficient. When you are working with cement blocks to build a masonry mailbox for your new house, you will need the following:
- Use trowels to apply, shape, and smooth concrete or mortar mix as you complete your DIY project.
- A level makes it possible to ensure that you create a solid, even ground level as you lay brick to build the mailbox.
- Investing in safety gear is crucial to ensure your protection against debris during brick wall construction. Protective eyewear and gloves will keep you safe when working on a masonry project.
Bricks (Standard or Decorative, Depending on Design)
The bricks you choose when learning how to build a brick mailbox will depend on your budget, what you want the mailbox to look like, and the level of durability you need for your mailbox. When looking for materials for your new DIY project, ask a Batchelder professional for design ideas that match your home’s aesthetics.
Mortar Mix (Type N or Type S)
To bind cinder blocks, bricks, or other types of cement blocks together, use mortar as a binding agent. For general use, use mortar type N, and for higher-strength materials, use mortar type S. Mortar helps hold the unit together, acts as a cushioning agent, fills in gaps, and creates a stable structure. Mortar gets harder as it dries, making the bond even stronger.
Concrete Mix (For the Foundation Slab)
When you learn how to build a brick mailbox, you will learn that the concrete mix used when building the foundation supports the overall stability of the mailbox. Concrete mix is generally a combination of cement, water, and aggregate, or sand and gravel. A solid, level foundation is needed so that the mailbox structure stays in place.
Gravel (For Base Leveling and Drainage)
You can use gravel to encourage drainage beneath the stone mailbox and to help create a level surface beneath your concrete slab.
Steel Rebar or Wire Mesh (For Reinforcement)
Steel rebar and wire mesh are used to reinforce the concrete base and brick structure. These will help to prevent cracking in the concrete and improve the durability of the project over time.
Metal Mailbox Insert (USPS-Approved)
When building your new mailbox, it is important to use a weather-resistant, USPS-approved mailbox insert while it is being built. Pay attention to the size and positioning of your insert so that your mailbox can be officially used.
How Can I Build a Brick Mailbox?

You don’t have to be a professional bricklayer to build your own brick mailbox. You simply have to follow a step-by-step guide and use the right materials for your DIY project.
Choose a Location and Check Local Regulations
Check with your local post office to learn about local ordinances, and also consult the USPS for more information on placement rules regarding the construction of a new mailbox. It is important to select a location that is easily visible to any mail carriers and is a safe place for your mail to be delivered.
Prepare the Base
To prepare the base of your mailbox, you will want to dig out the site and add gravel for drainage purposes. When pouring the concrete slab, make sure that it is level and you give the concrete enough time to cure before starting to build on the slab.
Lay the First Course of Bricks
When you lay the first layer of bricks, make sure that the first row is properly aligned. You will want to learn how to space the bricks correctly and create mortar joints as you work on your project.
Build Up the Mailbox Structure
Using a level and string line, you will want to stack bricks layer by layer. As you build up your brick wall, use rebar to reinforce the mortar and structure of your brickwork.
Leveling and Alignment
The structural integrity of your mailbox depends on how well you are able to level and align the bricks correctly. Take your time to carefully level each course of bricks — attention to detail is key to building a strong and attractive mailbox.
Install the Mailbox Insert
Once you have built your mailbox, place the insert securely and evenly. Mortar around the insert without damaging the finish to give your mailbox a professional look.
Ensuring a Secure Top Closure
Secure the top of the mailbox with care so that the structure is sound and aesthetically pleasing. Use mortar to finish the top layer, sealing any gaps to prevent water from getting into the mailbox and to ensure the durability of your project.
Finish the Top and Add Decorative Elements
Once you complete your mailbox, you can add a brick cap, stone top, or trim for aesthetics and protection. You can also add lighting or house numbers to your mailbox to elevate the look.
Clean Excess Mortar and Cure
For a long-lasting finish, allow the mailbox to cure properly before you use it. Pay attention to any excess mortar and clean it off before it cures.
Treat With Quality Masonry Sealer
Before sealing, clean the surface with water and a mild solution. Apply two coats of masonry sealer after everything is completely dry for extra durability and protection.
