Cedar vs. Pressure-Treated Wood for Mailbox Posts in Minnesota

If you're replacing your mailbox, one of the first decisions is what the post will be made of. At Father and Son Building, we build with both cedar-tone pressure-treated wood and real cedar, and we now offer composite as well. When they're installed correctly, both woods hold up well in Minnesota. They're just different materials with different strengths, and the right one comes down to what matters most to you.

Cedar-Tone Pressure-Treated Wood

Pressure-treated lumber is infused with preservatives that protect it from rot, decay, and insects, and it's made for use in and around the ground. It's a dense, strong wood that holds up well to the joinery and heavy-duty carriage bolts we use in our builds, and to the freeze-thaw cycles, snow, and road salt that come with a Minnesota winter.

The cedar-tone finish gives it a warm, natural color, and it can be stained or sealed if you want to customize the look. It's also the most cost-effective option, which is why it's the standard material on our estimates.

Real Cedar

Cedar protects itself naturally. Its oils make it resistant to rot and insects without any chemical treatment, which appeals to homeowners who prefer an all-natural material. It's lighter than treated lumber, with a distinctive grain and aroma, and it weathers to a soft silver-gray over time unless it's sealed.

Cedar is available as an upgrade on every build.

Built the Same Way, Either Way

Whichever wood you choose, the installation is identical. Every post is set on a gravel base for drainage, anchored in concrete, and protected below grade with Rotbloc. We add a weed-whip guard at the base to protect it from lawn equipment. Good installation matters just as much as the material.

How to Choose

Go with cedar-tone pressure-treated if you want great value and a classic look. Go with cedar if you love the look and character of natural wood. There's no wrong answer between the two.

If your top priority is a post you'll never have to maintain, take a look at our new composite option.

How Our Estimates Work

Every estimate includes cedar-tone pressure-treated as the standard material, with the cedar upgrade listed as a separate line item. That way you can see the difference in cost and decide for yourself.
