Michiana Mailbox Replacement Services designs, builds, and installs residential mailboxes.  We offer a 5-year "no hassle" warranty that includes repair or complete replacement of any damaged portions of your purchased and installed unit.  The warranty also includes making sure the post stays level and that the mailbox is opening and closing properly. Our goal is to keep the units looking and working as well as they did upon installation.  If there are any issues with your unit, we are motivated to solve them and expand our brand by keeping customers satisfied.



Prior to installation, we will call 811 (Know What's Below/Miss Dig) to make sure there are no concerns about digging or if a post is being moved to a new location.


All units are installed in accordance with USPS and AASHTO guidelines.


Haul-away services are included in price of installation, but...

SAVE $10.00 by disposing of your old post and mailbox yourself!
