What to Know About Cedar-Tone, Pressure-Treated Mailbox Posts

When customers see our mailbox posts, one question comes up a lot: "What kind of wood is that?"

Most of the time, the answer is cedar-tone pressure-treated wood. It's the standard material on our estimates. We also build with real cedar and composite, but treated wood has earned its place as our go-to for good reasons.

Here's what you should know about it:

Made for Ground Contact and Harsh Conditions

Mailbox posts live in tough conditions. They sit directly in the ground and deal with moisture, freeze-thaw cycles, road salt, and snow piled up by plows all winter.

Pressure-treated wood is made for exactly that. The treatment process drives preservatives deep into the wood, protecting it from rot, decay, and insects, including the portion below ground.

Strength Where It Counts

We build with 6x6 timbers because stability matters, especially for double, triple, and multi-unit structures. Pressure-treated lumber is dense and strong, and it holds up well to the weight of the boxes, wind, and seasonal ground movement. It also holds our joinery and carriage bolts tight over the years.

Built to Last

When you invest in a new mailbox, the goal is simple: do it once and not think about it again. Properly installed, cedar-tone treated wood is designed to last 15 to 20 years or more. That's especially important for HOAs and property managers who don't want to revisit the same project every few years.

A Warm, Natural Look

The cedar-tone finish gives treated wood a warm color that fits most homes and neighborhoods. It can also be stained or sealed to match your home or your HOA's standards.

Great Value

Cedar-tone treated wood offers strength, durability, and good looks at the best price point of any material we offer. That makes it a smart choice for homeowners and an easy choice for associations replacing many mailboxes at once.

Other Options

If you prefer the natural character of real cedar, we're happy to build with it, and it's available as an upgrade on every estimate. If you want the lowest-maintenance option available, ask about our new composite mailbox posts.

Whatever you choose, every post gets the same installation: a gravel base, concrete footing, Rotbloc below-grade protection, and a weed-whip guard.
