Is It Time to Replace Your Mailbox? How to Tell

Mailbox replacement isn’t a project you need to do often, but you should know when it’s necessary. A functional mailbox is key to receiving mail and an attractive mailbox creates a good first impression. Learn the signs that it’s time to replace a mailbox and get tips on how to replace a mailbox.

Replacing a Mailbox: Before You Begin

Before you replace a mailbox, be aware of requirements of the United States Postal Service (USPS), your local Post Office and, if you’re a member of one, your Homeowners Association or HOA. The Postal Service and your Post Office have requirements around:

  • Type
  • Size
  • Construction
  • Support
  • Placement

Your HOA might have additional requirements to ensure all the mailboxes in the neighborhood look the same.

When Mailbox Replacement Is Necessary

Replacing a mailbox might be necessary in several situations, but here are the most common reasons to replace a mailbox. 

Replace a Mailbox or Post if It’s Damaged Beyond Repair

Mailbox damage might be the result of vandalism and, for roadside boxes, a vehicle hitting the box. The mailbox might simply be worn or parts might be missing. Some mailbox maintenance and repair is possible, but it’s best to replace the mailbox entirely if:

  • The mailbox is misshapen to the point you can no longer close it securely.
  • The hinge points are damaged and the door or flag is missing.
  • It’s not possible to fasten the box securely to the post or the post is no longer secure in the ground.

Replace a Mailbox That Reduces Your Curb Appeal

Your mailbox is often part of the first impression your home creates. If there’s serious cosmetic damage or if the elements have taken a severe toll on the mailbox, it might be time for mailbox replacement to maintain your curb appeal. Consider mailbox replacement if:

  • Rust has damaged the mailbox beyond repair.
  • There are large dents in the box.
  • Mailbox repairs don’t fit HOA requirements.

Replace a Mailbox if You Need a More Secure Model

While a locking mailbox won’t prevent mail theft entirely, it’s much more secure than a standard mailbox. You might want to consider a lockable mailbox if:

  • Your Post Office and HOA allows a lockable mailbox in your neighborhood.
  • You typically receive checks or mail with important and sensitive information.
  • There have been cases of mail theft in your area.

Replace a Mailbox That’s Too Small

If you regularly receive lots of mail, large mail pieces or small packages, your mailbox might be too small. Consider replacing a mailbox with a larger model if:

  • Your Post Office and HOA allows the larger size.
  • It’s difficult for the postal carrier to fit your mail in the box and difficult for you to remove it.
  • The mail prevents the door from closing properly.

Replace a Mailbox That’s a Danger to Drivers or Pedestrians

If you have a roadside mailbox, you might realize the mailbox or support are unsafe for vehicle or foot traffic. You might need to replace or reinstall your mailbox if:

  • The mailbox is too close to the road based on USPS requirements.
  • The mailbox or support won’t break away easily if struck by a vehicle.
  • The mailbox extends into a sidewalk or other walkway.

How to Replace a Mailbox

If you decide replacing a mailbox is necessary, the good news is that it’s typically a simple project. Follow the instructions that come with your mailbox, but general steps are below.

Replacing a Mailbox at the Road

  1. Check with your post office and HOA for any requirements.
  2.  Remove the existing mailbox from the post.
  3. If necessary, dig up and replace or reinstall the post securely, following the USPS placement instructions.
  4. Attach the new mailbox to the post using a mounting board or bracket if necessary.
  5. Check to ensure the post and box are secure.

  2. Remove the existing mailbox from the wall.
  3. Mark the location for the new mailbox and drill fastener holes, ensuring the placement is level.

  5. Check to ensure the box is secure and opens easily.
