5 Questions You MUST Ask Before You Install a Mailbox

Love this post? Share it! :)

If you’ve got a dead mailbox hanging by a splinter, or it fell over and died the way mine did, then you’ve got to ask yourself the question, “Am I going to replace my own mailbox or do I need to hire a professional?”

Installing your own mailbox isn’t tough, but you have to ask a few more questions before you just jump right into it, which we’ll cover in this post.

Here’s how my dead mailbox looked when it finally keeled over!

5 Questions You MUST Ask Before You Install a New Mailbox

So before you jump into this project of installing a new DIY mailbox, ask yourself these important questions. You’ll thank yourself!

1. I’m Not Digging Up Utilities, Am I?

Did you know that if you dial 811 from anywhere in the U.S. they’ll put you in touch with your state’s call center, who will then contact your utility company to let them know you’re about to start digging in your yard? If you’re planning to dig anywhere in your yard, particular deeper than 24″ (at least, there’s what the freeze line is in my area, so check to see what your freeze line is, as well), you are required to have them come to your house to mark the location of utilities around the are you’re planning to dig (even if you’re hiring a professional to do the job).

You’re required to wait at least 2 days before you start digging. And then once they come to mark the location of buried utility lines, you’ve got 10 days to start digging.

It’s not just awesome that they do this, but necessary: if you don’t call 811 before you dig (or check out their website to check your own state rules), you could get hit with fees and penalties if you hit a utility (and it could be dangerous). It could cost you thousands of dollars! So be sure to know where utility lines are buried on your property before you start digging.

 

2. What Style of Mailbox Do I Want?

There’s the obvious of wood vs. plastic. But even the way it’s mounted makes all the difference in the world! There are top mounted ones and ones that extend on an arm, etc. Which one is best?

Then there is the popular kind that has a planter on the back of them and has an arm that extends outwards, which I think looks awesome!

….Or you can buy a butt-ugly plastic mailbox like this. HAHAHA.

You can also construct a really inexpensive pressure treated wooden mailbox post. It only costs about $25, and you could paint it to your liking.

If you’re trying to build your own mailbox, these are great DIY plans to build your own mailbox post, which is probably much more labor intensive, but so much more rewarding!

3. Am I Going to Accidentally Knock Down My Mailbox Post?

Yep, if you don’t take into account the type of mailbox you want (e.g. top-mounted one vs. one sitting on an arm), along with the USPC regulations on mailboxes, you could end up your mailbox extending past your curb, and then guess who’s going to accidentally  into it when she comes to visit on Christmas? Yep–your 85-year-old Aunt Betty.

Guidelines suggest 6″-8″ back from the edge of the curb. (FYI, USPC also says mailboxes should be 41″ to 45″ in height to the bottom of the mailbox edge.)

So, be sure to plan accordingly for your new mailbox post.

3. Do I Have All the Tools To Do This?

Tools aren’t too difficult, especially if you’re just installing a mailbox kit. If you’re building your own, it’s going to require a circular saw or some other method of cutting notches to join posts to create an “arm” to mount the mailbox. You’ll also need a screwdriver and some galvanized screws that won’t rust. You’ll also want to pick up a post digger, for about $35.

You can watch this video on how to use the post digger.

If you’re building your own post, you’ll also need:

  • a 4’x4′ about 6′ long (2′ will be buried) – You may also need a post depending on it you’re using a kit
  • Galvanized screwns or nails – They won’t rust.
  • Circular saw – for cutting notches to join the post with the arm.
  • Cement – Comes in a 50lb or 60lb bag.

 

5. How Do I Build a DIY Mailbox Post?

The key is making a plan and being patient, not rushing to do it. Now that you know the USPC mailbox guidelines on distance and height, and you know what style you want, you just have to figure out how to do it. If you’re just using one of the kits from the home improvement store, they’re pretty easy to assemble and probably have their own YouTube videos.

  1. Hello! We are replacing an existing mailbox but hope to use the 4×4 post already in place. (The post seems solid; the mailbox itself is ugly and cracked.) The post extends only 24 inches above ground, but most mailboxes we’ve looked at suggest the post should be 48 inches. Is it possible to use these mailboxes anyway, or does it have to be a 48-inch post (presumably with an additional 24 inches below ground)?

  2. I sent away for a post. It measures 3.25″ X 3.25″ inches (maybe 5 or six feet long). Is this solid enough? One installer told me it should be at least 3.5″ X 3.5″ or else the snow plow will knock if over. I live in Northern Virginia and get a big snow fall about once every two years. My current post is 3.5″ X 3.5″.

  3. From your “5 questions-must-ask-install-a-mailbox” post: just a technical issue – in your blog you have written: “a 4’x4′ about 6′ long (2″ will be buried) ” While it may quickly be obvious to anyone reading it, I feel you should correct it to read “a 4″x4” about 6′ long (2′ will be buried) “. Thanks

    1. Great catch, Bill!! Sometimes it’s just one extra little mark that makes all the difference! 🙂 Will fix it now. Thanks!!
