Mailbox installation: a guide for pros
What customers ask, how to win the job, and what to put on your profile.
Offering mailbox installation
You install mailboxes, setting posts in firm foundations, fitting boxes and hardware and checking that the box is at the right height and distance for the carrier. Customers judge you on a post that does not move and a box that opens cleanly for years.
What customers ask
- How deep do you set the post?
- Will the post survive a plow?
- Can you put the box on the house wall?
- Will you take away the old post?
- Where is the right spot for the box?
How to win the job
- On the first call, ask for the post type, the box model, the soil type and photos of the location, then confirm the spot with the customer.
- Call the locating service before you dig, and mark the buried lines on site.
- Set the post plumb and in a firm foundation, and let the concrete cure before the box goes on.
- Check the box height and the reach from the road, and confirm the spot with the customer before you finish.
- Test the post with a firm push and the box with a full open and close before you leave.
- In the quote, list the post, the foundation, the old post removal and the location check.
What to put on your profile
- Photos of plumb posts, firm foundations and neat box mounts
- The post and box types you install, listed by name
- Whether you install post-mounted and wall-mounted boxes, and which materials you use
Follow-up that helps the customer
- Offer a check of the post after the first winter, when frost has moved the ground
- Suggest repainting or treating a wood post every few years to slow rot
- Remind the customer to clear snow and debris from around the box so the carrier can reach it
Licenses and permits
Mailbox installation is generally not licensed as a trade. Check state and local rules with your licensing agency or business office for any business license that applies, and check road or right-of-way rules for the box placement.
Questions
Do I need a license to install mailboxes?
Requirements vary. Many areas do not license mailbox work, but some require a business license for paid work. Check with your state or local licensing agency or business office.
