Here are the factors to consider when determining how much it costs to install a letterbox for parcel delivery:

Letterbox type and quality

Some letterboxes are steel and plastic, while others are resin, copper, and stainless steel. On the more expensive side of the spectrum are hand-painted metal and handmade wood letterboxes. 

Post type and quality

Pressure-treated pine and simple steel are some of the cheapest types of posts available. There are also moderately priced PVC and metal ones with a wrought-iron appearance or other decorative flairs. High-end posts include faux ledge stone, stucco pillars, and box enclosures.


You can purchase letterbox kits with a steel post driven into the ground. With these kits, you don't need additional supplies. Usually, you just need a bag of concrete mix to support a letterbox with a wooden post. Do you have posthole diggers, saws and other tools? If not, you have to buy and add them to the overall cost.


Customising your letterbox might involve sticking house numbers and letters for your name. These are the usual options. If you want a more sophisticated look, wood and metal in different finishes are also available. 

Labour costs

Are you hiring a handyman to install your letterbox for you? The cost will depend on the estimated time for the project. The handyman will check how much assembly is needed, how hard and firm the ground is for digging, and how far your home is.

What are the types of letterboxes and their advantages?

  1. Residential curbside letterboxes are the most common. You can find them at the end of driveways. You can attach one to a vertical post and put a flag letting the mailman know there’s mail for pickup. This makes it easier for you to send and receive mail.
  2. Door slots are prevalent in highly urbanised cities with limited spaces. They take minimal space and are usable regardless of the weather, as you don't need to go out to get your mail. However, sending mail is a bit challenging; you have to hang it outside the door in the hopes of the mailman noticing it. Aside from that, a mail slot might allow strangers to peek inside your house.
  3. Lobby letterboxes are often in multi-unit buildings that don't have individual letterboxes. One advantage is security. Your mail is in a locked box, preventing theft.

Letterboxes are vulnerable to wear and tear, so conduct an annual letterbox checkup to prevent damage. Over the years, try to resolve issues as soon as you notice them. For instance, tighten loose hinges and replace rusty or loose parts. Keep the path to your letterbox clear for easy access.
