Mailbox Legal Height Dimensions and Restrictions
Before starting your mailbox replacement, it’s important to know the legal requirements:
- Height: The mailbox should be positioned 41 to 45 inches from the ground to the bottom of the mailbox.
- Distance from the road: The front of the mailbox should be approximately 6 to 8 inches from the curb or road edge.
Following these guidelines will help ensure your mailbox complies with the U.S. Postal Services regulations and reduce the risk of future damage.
Standard Mailbox Sizes
There are three standard sizes of mailboxes:
- Small (T1): 5 inches wide x 6 inches tall x 18.5 inches long
- Medium (T2): 6 inches wide x 7 inches tall x 19 inches long
- Large (T3): 8 inches wide x 11.5 inches tall x 22.5 inches long
I always tell my customers to choose a size that fits their typical mail volume and any special needs, such as parcel delivery.
Step-by-Step Guide to Replace a Mailbox
Tools and Materials I Would Recommend:
- New mailbox
- Post (wood or metal)
- Post hole digger or shovel
- Quick-setting concrete
- Level
- Tape measure
- Screwdriver or drill
- Screws or mounting hardware
Start by removing the remnants of the old mailbox and post. If the post is broken, you may need to dig out the old concrete base.
2. Dig the HoleHere's the fun part, use a post hole digger and dig the hole at least 2 feet deep. The hole should be wide enough to accommodate the new post and provide stability.
3. Set the PostPlace the new post in the hole. Use a level to ensure it’s straight. Pour quick-setting concrete around the post, filling the hole about halfway. Add water to the concrete as directed on the package and mix. Allow the concrete to set for about 10-20 minutes.
4. Secure the PostOnce the concrete has set, fill the remainder of the hole with dirt and pack it firmly around the mailbox post. Check again with a level to ensure the post is still straight.
5. Attach the MailboxUsing the provided screws or mounting hardware, attach the new mailbox to the post. Make sure the mailbox door opens freely and is securely mounted.
6. Final AdjustmentsDouble-check the height and distance from the curb to ensure compliance with regulations. Make any necessary adjustments before the concrete fully hardens.
Average Cost to Install a Mailbox
The cost to have a typical roadside mailbox installed by our team can vary depending on several things, which includs the type of mailbox, the materials used for the post, and of course labor charges. Here's a typical breakdown:
1. Mailbox and Post Cost:
- Standard mailbox: $20 to $100, on average depending on size and material.
- Post: $25 to $50 for a basic wooden or metal post, a very decorative option could be even more.
2. Labor Costs:
- Professional installation: I would say are charge typically ranges between $150 to $400, depending on the complexity of the job, location, and any additional work like removing old concrete or dealing with special mounting requirements.
3. Concrete and Supplies:
- Quick-setting concrete: $5 to $10 per bag (you may need 1-2 bags).
- Miscellaneous supplies: Screws, brackets, and other mounting hardware might add $10 to $20.
In total, I'd say you should expect to pay anywhere from $150 to $500 for a typical complete roadside mailbox installation, including materials and labor. Of course I think these are for standard mailboxes. I mean you could opt to buy a $2000 mailbox if you wanted to and we would install it.
