How it works
Dig & set the post
We dig the hole to the correct depth for your soil type, mix fast-setting concrete, and hold the post plumb until it cures enough to stand on its own.
Attach the box
We mount the mailbox securely to the post at the regulation height and confirm the door opens and closes without binding.
Finish & clean up
We pack the remaining soil around the base, replace any disturbed grass or gravel, and haul away the old post and box if requested.
Problems we fix
- Post set too shallow — leans over the first time a snowplow passes
- Mailbox mounted too low or too far from the road for carrier delivery
- Post not plumb, making the box tilt to one side
- Old concrete collar not fully broken up, causing new post to sit crooked
Mailbox Installation — FAQ
Do I need to call 811 before you dig?
Yes — please call 811 or use your state's online utility-locating service before our visit. We need utilities marked to dig safely. We will remind you at booking.
Can you remove the old mailbox and post?
Yes. We can pull out the old post, break up any concrete footing, and haul everything away as part of the job.
What USPS height requirements apply?
The mail slot should sit 41 to 45 inches above the road surface, and the box should be 6 to 8 inches back from the curb. We follow these guidelines on every install.
