A mailbox is a small thing until yours is leaning at 45 degrees, rotted through at the base, or lying in the ditch after someone clipped it. Between Houston's clay soil heaving posts and the occasional bumper, mailbox posts here don't last forever. We install and replace mailboxes across the Houston area — single post-mount boxes, locking boxes, and the cluster units that serve whole streets and complexes — and we set them to stand straight and stay put.
Mailbox and post installation and replacement
The most common call is a post that's failed — rotted at the ground line, leaning as the clay soil moved, or knocked over. Mailbox post replacement means setting a new post plumb and solid, in concrete, so it stands straight and stays that way.
We handle full mailbox replacement — new box and post together — and box-only swaps where the post is still sound. Wood posts, metal posts, and decorative cast styles, with the box mounted at the height and setback the postal carrier needs to reach it. Whether it's a fresh install on a new home or replacing one that's seen better days, we set it to USPS placement guidelines so there's no problem with delivery.
Locking and security mailboxes
Mail theft is real, and a locking mailbox is the simple fix. Locking mailbox installation gives you a box where mail drops through a slot into a secured compartment only you can open with a key — so checks, cards, and packages aren't sitting in an open box all day.
We install locking post-mount and wall-mount security mailboxes, sized for the mail volume you actually get, and set on a solid post like any other. For a lot of Houston neighborhoods it's the cheapest security upgrade a house can get, and it goes in the same visit as a post replacement if you're already redoing the mailbox.
Cluster mailboxes and CBUs
Cluster box units — CBUs — are the multi-tenant mailboxes that serve subdivisions, apartment complexes, and commercial developments from one central, locked unit. Cluster mailbox installation and CBU mailbox installation are heavier jobs than a single box: the unit is large and has to sit dead level on a solid pedestal or a concrete pad.
We install and replace USPS-approved CBUs, set the pedestal in concrete so the unit stays plumb and secure, and place it to meet postal access requirements. For a property adding units or replacing a rusted, broken, or vandalized cluster box, we handle the pad, the pedestal, and the unit so it's set right and built to last.
Apartment and HOA mailboxes
For apartments, complexes, and HOA neighborhoods, mailboxes usually have to match a standard — the same style, color, and layout across the property — and that's most of the job.
Apartment mailbox installation covers the horizontal and vertical tenant boxes and cluster units that serve multi-family properties. HOA mailbox replacement means matching the neighborhood's required style so a replaced box blends in and passes architectural rules — a single leaning or mismatched mailbox is exactly the kind of thing an HOA writes letters about. We source the matching unit and set it to the standard, so the property stays consistent and compliant.
Setting posts that last in Houston
The reason mailboxes lean here is the same reason fences and decks fail — the clay soil moves, and a post set shallow or in loose dirt moves with it.
We set posts in concrete footings deep enough for the soil, plumb, and tamped solid, so the box stands straight through the seasons instead of tilting after the first wet-dry cycle. Wood posts get set to shed water at the base rather than wick it up and rot. It's a small thing done right, and it's the difference between a mailbox that stays straight for years and one you're re-standing every couple of seasons.
What mailbox installation costs in Houston
Mailbox work spans from small to a real project. A box-only swap onto a sound post is the low end; a new post-and-box set in concrete is modest; a locking mailbox adds the cost of the box itself; and a cluster/CBU unit on a new pedestal and pad is the high end because of the unit and the concrete.
What moves the number: box-only versus new post, standard versus locking versus cluster, the box and post style, whether HOA-matching is required, and the concrete work for a post or pedestal. These are ranges, not quotes — tell us what you need and we'll price it.
Frequently asked questions
Can you replace a leaning or rotted mailbox post?
Yes — that's the most common call. We set a new post plumb and in concrete, deep enough for Houston's clay soil, so it stands straight and stays put. We can replace the box and post together or just the post if the box is still good.
Do you install locking mailboxes to stop mail theft?
Yes. A locking mailbox drops mail through a slot into a secured compartment only you can open, so it isn't sitting in an open box all day. We install locking post-mount and wall-mount boxes on a solid post — a cheap, effective security upgrade.
Do you install cluster mailboxes and CBUs?
Yes — USPS-approved cluster box units for subdivisions, apartments, and commercial properties. The unit has to sit dead level on a solid pedestal, so we set the pedestal in concrete and place it to meet postal access requirements. We handle the pad, pedestal, and unit.
Can you match our HOA's required mailbox style?
Yes. HOA and apartment mailboxes usually have to match a standard style and color, so we source the matching unit and set it to the neighborhood's requirements. A mismatched or leaning box is exactly what an HOA flags, and matching it keeps the property consistent.
Do you set the post in concrete?
Yes — plumb, in a concrete footing deep enough for the clay soil, and tamped solid. That's why Houston mailboxes lean: a post set shallow or in loose dirt moves with the soil. Setting it in concrete is what keeps it straight through the seasons.
How much does mailbox installation cost in Houston?
A box-only swap is the low end; a new post-and-box in concrete is modest; a locking box adds the box cost; a cluster/CBU on a new pedestal and pad is the high end. Box style, HOA matching, and concrete work move the number. We price after you tell us what you need.
