How to install mailbox post without concrete

Whether you have an old mailbox post that has rotted away or you just don’t like the one you have, installing a new one is a simple process that can be completed in one day. You can find pre-cut mailbox posts made of wood or metal at almost any home improvement store. They come in many varieties and lengths. If you are choosing a wood mailbox post, be sure to buy pressurized wood for the longest life possible.

Remember before you do any digging anywhere, you should call the North American One Call Referral Service to be sure you are not going to damage any utility lines that may be running through your property. The number for One Call is 1-888-258-0808. Once you have called and know that you are about to dig into a safe place you are ready to begin.

Be sure to call your local post office for specific regulations about heights and placements of mailboxes. The federal regulation for post height is  41″ to 45″ inches from the ground to the bottom of the mailbox. The post should be at least two feet from the side of the road so that your mail carrier can safely pull off the side of the road to deliver your mail.

If you have purchased an extended mailbox post, be sure to compensate for this when you decide where you will place your post. An extended post means that the mailbox will be set closer to the road than it would be if placed on a straight post. Your local post office will be able to tell you what side of the road the box should be placed in the event that you are installing a box on a new property for the first time.

Installing a mailbox post can seem like a daunting task, but with the right tools and a little know-how, it’s actually quite simple. In this article, we’ll walk you through the steps of installing a mailbox post without concrete.

When it comes to installing a mailbox post, concrete is often the go-to option for providing a solid foundation. However, there are situations where using concrete may not be feasible or desirable. Fortunately, there are alternative methods that can offer stability and secure your mailbox post without the need for concrete. Let’s explore these methods in detail.

Using an Anchor Kit

One way to install a mailbox post without concrete is by using an anchor kit. An anchor kit typically includes a 20″ crossbar that provides leverage for screwing the anchor into the ground. Here’s how you can do it:

  1. Dig a hole for the anchor according to the manufacturer’s instructions.
  2. Place the anchor in the hole and ensure it is level.
  3. Use a wrench or socket set to screw the anchor into the ground until it is firmly secured.
  4. Once the anchor is in place, set your wood post on the bracket provided in the kit.
  5. Attach the wood post to the anchor using 5 lag bolts, which are usually included in the kit.
  6. The anchor bracket typically has pre-drilled holes for easy attachment.

Using an anchor kit can provide a stable foundation for your mailbox post without the need for concrete.

Using Sandbags

Another method for installing a mailbox post without concrete is by using sandbags. Sandbags offer a simple and temporary solution to stabilize the post. Here’s how you can do it:

  1. Fill a sandbag with sand until it is tightly packed.
  2. Place the sandbag around the base of the mailbox post.
  3. Ensure that the sandbag is snugly positioned to provide stability.
  4. Repeat the process with additional sandbags if needed.

Using sandbags can help keep your mailbox post in place and provide temporary stability. However, it’s important to note that sandbags may not offer the same level of durability as other methods.

Using Gravel, Landscape Fabric, and Crushed Stone or River Rock

If you’re looking for a more permanent solution, you can use a combination of gravel, landscape fabric, and crushed stone or river rock to create a stable base for your mailbox post. Here’s how:

  1. Dig a hole for the mailbox post according to the desired depth.
  2. Fill the hole with gravel, ensuring it is compacted.
  3. Wrap the mailbox post with landscape fabric to prevent weed growth around the post.
  4. Place the post in the hole on top of the gravel.
  5. Fill the hole with crushed stone or river rock until it reaches the desired level.
  6. Compact the crushed stone or river rock to provide stability.

By using this method, you create a solid base for your mailbox post, preventing shifting or leaning over time.

Using a No-Dig Mailbox Post

For a hassle-free installation, you can opt for a no-dig mailbox post. These posts are designed to be driven into the ground without the need for digging or concrete. Here’s how to install a no-dig mailbox post:

  1. Choose a suitable location for your mailbox.
  2. Use a mallet or a hammer to drive the post into the ground until it reaches the desired height.
  3. Ensure that the post is firmly set in the ground.
  4. Attach your mailbox to the post according to the manufacturer’s instructions.

No-dig mailbox posts provide a convenient and efficient way to install your mailbox without the need for concrete or extensive digging.


Installing a mailbox post without concrete is possible with various alternative methods. By using an anchor kit, sandbags, gravel, landscape fabric, crushed stone, river rock, or a no-dig mailbox post, you can achieve a stable foundation for your mailbox. Consider your specific needs and preferences when choosing the installation method that works best for you. Now you can enjoy a secure and functional mailbox without the use of concrete!
