Cedar vs. Pressure-Treated Pine Fence in Tennessee

August 20, 2026

Almost every wood fence conversation we have starts here. Cedar or pressure-treated pine. The cedar has natural oils that fight rot and insects, and it holds its shape well. Pressure-treated pine gets its rot and insect resistance from chemicals forced into the board, costs less, and moves around more while it dries.

Cedar vs pressure treated fence, the short version

We build with both. Cedar is naturally durable, and the oils in the heartwood are what discourage rot and bugs. Pine has no defense of its own, so it goes through a treatment process that pushes preservatives into the wood under pressure.

The difference you actually notice shows up after installation. Cedar holds its position. Treated pine moves, and how much depends on how wet it was on delivery, how fast it dries, and whether the fence was built to allow for that. For styles and layouts, our wood fence options page walks through the builds we do most.

Cost

Pressure-treated pine is the cheaper material by a wide margin. Cedar runs higher per board, and on a long run of privacy fence that gap adds up fast. For a pasture perimeter or a backyard where the budget is the deciding factor, treated pine is usually the sensible call.

Cedar earns its price on stability and looks. Fencing a small backyard in Franklin or Brentwood where you see the fence from the patio every day? Most of our customers go cedar and don't regret it. On acreage out in Culleoka or Hampshire, pine does the job. We'll price both on your actual layout so you can see the spread.

Stability, warping, and what happens as boards dry

Treated pine shows up heavy and damp because the treatment saturates it. As that moisture leaves, boards shrink, cup, twist, and check. A lot of that is cosmetic. The rest pulls fasteners loose or opens gaps where you didn't want any.

Cedar arrives drier and lighter and it rides out seasonal swings better. You'll still get checking on cedar, especially wide boards facing the afternoon sun. What you won't see as often is the hard twist that turns a pine picket into scrap. Building practice matters either way. We fasten with movement in mind, we don't jam wet pine boards tight against each other, and we set posts so the frame stays true while the pickets settle.

Appearance and how each one weathers

Left alone, cedar fades to a soft silver-grey. Plenty of our customers never put anything on it. The grain still looks good as it ages and the color change comes in fairly even.

Pine greys too, just unevenly, and depending on the treatment it can carry a greenish cast early on. Water sitting on a board leaves dark blotching behind. Knots run bigger and more frequent in fence-grade pine. Cedar takes less work to get an even look.

Stain and sealer

Treated pine has to dry before it will take a finish. Put stain on wet boards and it sits on the surface and peels off in sheets. Cedar can usually be finished sooner, and the tighter grain pulls semi-transparent stain in evenly. One catch with cedar is tannin bleed under certain finishes, so the product you pick matters.

Either wood lasts better with a finish on it. Our page on staining and sealing a fence covers timing and what we recommend for each. For how each one holds up in this climate, we get into that on how long fences last in Tennessee.

Middle Tennessee humidity, sun, and clay

Summers here are humid and hot, winters swing hard, and ice storms put real weight on a fence line. Wood goes through wet-dry cycle after wet-dry cycle, which is what drives the warping in treated pine and what makes cedar's stability worth paying for. South and west exposures cook the surface and grey both species faster.

The ground matters as much as the wood. We hit rock on plenty of lines around Maury County, and clay holds water right against the posts. Check setbacks, easements, and height limits with your city or county before we build. The rules aren't the same in Columbia, Spring Hill, Mt. Pleasant, Fairview, Santa Fe, or Chapel Hill over in Marshall County.

How we handle the work

We walk the line with you and talk through both woods on your property, and where one clearly beats the other we say so. On install day we sort boards as we go and cull anything already twisting. We set the posts, build the frame, and hang the gates ourselves.

Common questions about cedar and treated pine

Is cedar worth the extra cost over pressure-treated pine?

It depends on what the fence is doing. For a visible backyard fence you'll look at every day, cedar's stability and cleaner appearance usually justify it. For long runs where the job is containment, treated pine does the work for less money.

Will pressure-treated pine warp no matter what?

Some movement is normal as it dries. How bad it gets comes down to the lumber you start with and the way it's fastened. We pick through the stack and build with drying in mind, which keeps most of it in the cosmetic range.

Do I have to stain a cedar fence?

No. Cedar holds up unfinished and weathers to grey. Staining keeps the warmer tone and adds surface protection, so it's a preference call more than a necessity.

Can I mix cedar and treated pine on the same fence?

Yes, and people do it often. Treated posts with cedar pickets is a common combination that puts the rot-resistant material in the ground and the good-looking material where you see it.
