A Weekend Project with Big Results

Installing a post-mounted mailbox is one of the most rewarding DIY projects you can tackle in a single afternoon. However, because this fixture sits at the edge of the road, it needs to be installed correctly to withstand the elements (and the occasional snowplow spray). Here is our professional guide to getting it right the first time.

Step 1: Gather Your Tools

Before you start digging, make sure you have the following:

• Post-hole digger or shovel.

• Level (Crucial for a modern, straight look).

• Quick-set concrete (1–2 bags).

• Measuring tape.

• Water.

Step 2: Know the USPS Regulations

To ensure your mail carrier can deliver your mail safely, you must follow these USPS standards:

• Height: The bottom of the mailbox must be 41 to 45 inches from the road surface.

• Setback: The post should be 6 to 8 inches back from the curb or edge of the road.

Step 3: Digging the Hole

For a sturdy post that won't lean over time, we recommend digging a hole roughly 24 inches deep. This ensures the post is anchored below the frost line in most regions, preventing the ground from 'pushing' the post up during winter.

Step 4: Setting the Post

Place your post in the center of the hole. Pour in your quick-set concrete and add water according to the bag's instructions. This is the most important part: Use your level on two adjacent sides of the post to ensure it is perfectly vertical while the concrete sets.

Step 5: Mounting the Mailbox

Once the concrete has cured (usually 20–40 minutes for quick-set), it’s time to attach your Vsons Design mailbox. Our mailboxes come with pre-drilled holes and mounting hardware, making this final step the easiest part of the process.

Conclusion: Maintenance for Longevity

With a marine-grade aluminum or 304 stainless steel mailbox, your maintenance is minimal. A quick wipe-down with a damp cloth once a season is all it takes to keep your new architectural statement looking brand new for years to come.
