DIY Methods for How to Fix a Mailbox Door


A broken mailbox door can be very annoying for your mail carrier and can lead to a host of problems for your mail.  If your door is barely hanging on, as in the above picture, your mail is in full view for anyone passing by (think theft of small packages).  Your mail is also subjected to the weather which can lead to having your mail blown away by the wind or even worse, wet mail.  Here are a couple of quick and easy DIY ways on how to fix a mailbox door.

This is the way to go if you have a brick encased mailbox.  This door is designed so that it snaps into your existing mailbox opening and is held in place from the inside with spring-loaded metal clips.  You are not required to do any cutting, drilling, or anything else destructive.  You do have to remove your current door, if it’s still attached.  Then, just take the replacement door and “snap” it into the opening of your existing mailbox and you are done.  If you are leery about whether or not this really does work, check out the near perfect reviews on Amazon.

Perhaps the biggest advantage of this route is that you don’t have to tear up your brick to replace the whole mailbox.  These come in different sizes so measure your door height to see if you have the standard 6.25″ or the standard 8″.  These are available in black, white or natural aluminum.

You can also buy these directly from the Bayshore Mailbox Company.


Retrofit Door Latches

Perhaps your door structure is in good shape, but it just keeps falling open!  Whether it’s due to the wind blowing it open and or it simply just won’t stay latched, you may need to look into replacing the latch and handle.  Fortunately, you can buy these as replacement parts pretty cheap.  Here is a solid one for $12.50.



Built to last, it is made of aluminum and painted black.  It attaches with a couple of screws to the mailbox and another couple of screws to the mailbox door.  It’s a very simple repair and solves an annoying problem.


Likewise, if you only need the top latch, it is also available here for less than $10.00.

Plastic Mailboxes

If you have a plastic mailbox, you may just be experiencing a clasp that is functioning incorrectly and failing to keep the door closed.  If you really love your current plastic mail box, you can buy a latch set for plastic mailboxes for under $20.

However, at this price point, we recommend just replacing your mailbox.  There are many plastic mailboxes available at this price or even less.
