Mailbox Cost Factors

The ranges in the table at the top are broad. This section and the itemized list below will clarify what your costs will be.

  • Mailbox Type and Quality: Mailboxes ranges from cheap steel and plastic boxes to the popular resin post & mailbox kits to copper and stainless steel. Some hand-painted metal and handmade wood mailboxes are very expensive.
  • Post Type and Quality: Pressure-treated pine is the cheapest type followed by simple steel posts. Quality PVC posts and metal posts with wrought-iron appearance or other decorative flairs are moderately priced. On the high end are faux ledge stone and stucco pillar and box enclosures that install over a wood or steel post for support.
  • Supplies: Some mailbox kits include a steel post that is driven into the ground, so no additional supplies are needed. A bag of concrete mix is usually all that is needed when using a wood post for support. If you have to buy tools such as a posthole digger, saw and other hand tools, cost will rise.
  • Accessories: Peel & stick house numbers and letters for your name are the cheapest. Wood and metal in a range of finishes are also available.
  • Who Installs: If you hire a handyman service for the work, the cost will be based on estimated time for the project. The handyman will consider how much assembly is required, installation of numbers and letters, how hard the ground is for digging and the distance traveled to reach your home.

Permits, Inspection, and Installation Costs

No permit is required for installing a mailbox and post of the types we’re discussing. It may be beneficial however, to call ahead to 311, or DigSafe, to assure you are not digging in an area with buried utilities.

Permits and Inspection

  • $0 | Not usually required, however, check with your HOA for restrictions if applicable.

Installation Cost and Time

Installing a post and mailbox is a common reason to hire a handyman. This is a one-person job, and as noted, it will probably be priced by the time and materials required. Independent handymen charge less than large handyman services, but might not be licensed or insured. Sometimes retirees offer handyman services at very affordable rates.

  • $55 – $125 | Minimum fee from most handyman services for up to 1 hour of work
  • $40 – $75 per hour | Additional labor, if needed

Completed Installation Time

This job should go quickly if there are no complications.

  • Up to 1 hour | Simple installation including digging a hole in soft soils, setting a post, backfilling with concrete, attaching the mailbox and installing the house number on the box or post.
  • 1-2 hours | Complex installation when the soil is very hard or assembly of a post and box kit is time-consuming.

The last time I had to replace my mailbox, it was discovered during a routine exterior home inspection to be wobbly and the post was rotted at the base. This job takes time and effort more than it requires expertise. It’s certainly a DIY job if you have a few hours to devote to it and are in good physical condition for digging. Do-it-yourselfers save an average of $115 to $150 in labor costs.

If you tackle the job, this flier from the USPS provides useful information on mailboxes and installation including these:

  • Mailboxes must be placed 6 to 8 inches away from the curb; the slot or door must be 41 to 45 inches from the ground.
  • Curbside mailbox posts should be buried less than 24 inches deep and made from wood no larger than 4 inches high by 4 inches wide. Steel or aluminum pipes with a 2-inch diameter are also acceptable.
