Step 1: Prepare the Foundation
A strong foundation is essential for stability.
-
Mark the location and dig a hole about 12 inches deep and slightly wider than your planned mailbox base.
-
Place a layer of gravel at the bottom for drainage.
-
Mix and pour concrete into the hole, ensuring the surface is level.
-
Insert rebar vertically into the wet concrete for added structural strength.
-
Allow the foundation to cure for at least 24 hours.
Step 2: Lay the First Layer of Bricks
Once the foundation is ready:
-
Mix the mortar according to package instructions.
-
Spread a layer of mortar on the foundation base.
-
Place the first row of bricks, checking alignment with a level.
-
Maintain even spacing (mortar joints should be about 3/8 inch thick).
Proper alignment in the first layer ensures the entire structure remains straight.
Step 3: Build the Mailbox Walls
Continue adding rows of bricks:
-
Stagger each row for strength and visual appeal.
-
Apply mortar to the top of each brick before placing the next layer.
-
Use a level after each row to maintain vertical alignment.
As you build, leave an opening for the mailbox insert at the desired height.
Step 4: Install the Mailbox Insert
When you reach the correct height:
-
Place the mailbox insert in the opening.
-
Surround it with bricks, ensuring it is securely supported.
-
Apply mortar carefully around the insert to seal gaps without blocking the door.

Step 5: Cap and Finish
Once the structure reaches your desired height:
-
Add a decorative brick or stone cap to protect the top from weather damage.
-
Smooth mortar joints with a jointing tool for a clean finish.
-
Clean excess mortar from the bricks with a damp sponge.
Allow the structure to cure for several days before placing mail inside.
Step 6: Maintenance Tips
A brick mailbox requires minimal upkeep, but regular checks can extend its life:
-
Inspect for loose or cracked bricks annually.
-
Clean the surface with a gentle brush and mild soap.
-
Reapply mortar if joints begin to wear.
Safety Considerations
When building a mailbox with bricks, always wear gloves, safety glasses, and sturdy footwear. If you’re not experienced with masonry work, consider hiring a professional for structural stability and compliance with postal standards.
