Quick answer: Cedar fencing lasts 15–25 years and looks better as it ages — but costs 40–60% more upfront than pressure-treated. Pressure-treated pine costs less ($4,500–$9,000 for a typical 150' residential project) but lasts only 10–15 years and requires re-sealing every 2–3 years. Choose cedar for long-term ownership and aesthetics; choose pressure-treated for strict budget or short-term properties.
| Factor | Cedar | Pressure-Treated Pine |
|---|---|---|
| Upfront cost (150' project) | $6,500 – $14,000 | $4,500 – $9,000 |
| Lifespan | 15–25 years | 10–15 years |
| Rot resistance | Natural (cedar oils) | Chemical treatment (copper) |
| Sealing | Optional | Required every 2–3 years |
| Color over time | Red-brown → silver-gray patina | Greenish → gray (often blotchy) |
| Dimensional stability | Stable — minimal warping | Prone to warping/twisting |
| Insect resistance | Excellent (natural) | Good (treatment) |
| Best for | Long-term ownership, aesthetics | Budget projects, short-term properties |
Both are real wood. Both can be cut, drilled, and modified on site. Both can be stained any color. Both look natural in the landscape. Both can be repaired by replacing individual boards or pickets. Both meet pool code with proper picket spacing. Both accept self-closing pool-rated hinges.
The differences are in longevity, aesthetics over time, and upfront cost. That's where the decision lives.
Cedar grows in the Pacific Northwest (specifically Western Red Cedar from Washington, Oregon, and British Columbia). It takes decades to grow to dimensional lumber size, and the wood contains natural oils (thujaplicin) that resist rot, insects, and decay without chemical treatment. The result is a premium material that costs more to harvest, ship, and mill.
Pressure-treated pine, in contrast, is mass-produced southern yellow pine that's chemically treated with copper-based preservatives. It grows fast, ships short distances, and competes on price. For most outdoor lumber applications — decks, raised beds, fence posts — it's the standard.
Cedar weathers gracefully. Left untreated, it transitions from warm red-brown to a uniform silver-gray patina over 1–2 years. The grain stays beautiful. Old cedar fences look intentional — like driftwood, like cedar shingles on a coastal cottage. Sealing every 4–5 years preserves the red-brown if you prefer.
Pressure-treated pine ages differently. The greenish factory tint fades to a gray-brown over the first year, often blotchy. Pickets warp and twist. Knots fall out. Unstained PT looks tired after 5 years. The fix is to stain it from year one — which adds $300–$500 in materials and a weekend of labor every 2–3 years for the life of the fence.
If you've ever driven through an older suburban neighborhood and seen a wood fence that looks great after 15 years versus one that looks awful after 8, the difference is usually cedar vs untreated pressure-treated.
Let's run real numbers for a 150-foot residential privacy fence:
Cedar costs about $1,800 more over 20 years — and you're not replacing the fence at year 15. For most homeowners, that math favors cedar. But if you're moving in 5–10 years, pressure-treated captures most of the value with significantly lower upfront cost.
Choose cedar if you: plan to stay in the home 10+ years, value aesthetics (especially a fence that looks better with age), want low-maintenance (sealing optional, not required), have a wooded or naturalistic property, or simply want the longest-lasting wood option short of going to vinyl.
Choose pressure-treated if you: are working with a strict budget, plan to move within 5–10 years, are okay with regular staining as part of yard maintenance, or want the flexibility to paint a specific color (PT accepts paint better than cedar over time).
Still not sure? Cross-shop both against vinyl — if you're going to invest in cedar, the case for vinyl gets stronger too (similar lifetime cost, even lower maintenance).
Usually yes. Cedar costs roughly 40–60% more upfront but lasts 5–10 years longer, looks significantly better as it weathers, and doesn't require chemical treatment. For homeowners staying in the property 10+ years, cedar's longer lifespan and better aesthetics typically justify the premium. For short-term ownership or strict budget projects, pressure-treated is the right call.
Cedar lasts 15–25 years untreated and up to 30 years with periodic sealing. Pressure-treated pine lasts 10–15 years before posts start to fail, regardless of how well it's maintained. Both estimates assume proper installation with adequate post depth and drainage.
No. Cedar can be left to weather naturally — it turns a beautiful silver-gray patina over 1–2 years and the wood remains structurally sound. Sealing preserves the original red-brown color and extends life by 5–10 years, but it's an aesthetic choice, not a structural requirement.
Modern pressure-treated lumber uses copper-based preservatives (typically ACQ or MCA) that are safer than the older CCA-treated wood used before 2004. It's safe for outdoor use including pet enclosures and play areas, but we don't recommend it for raised garden beds because residual copper can leach into soil.
Cedar is naturally rot-resistant — the oils in the wood resist insects and moisture without chemical treatment. Western Red Cedar (what we use) grows primarily in the Pacific Northwest, so it incurs significant shipping cost to the East Coast. Pressure-treated pine grows in southern PA and the southeastern US and is mass-produced for outdoor lumber, keeping costs lower.
Not cost-effectively. Removing an existing wood fence is roughly 30–40% of the cost of a new install (post removal, debris haul-away, disposal). If you'll want cedar eventually, install cedar from the start. The exception is a temporary fence for a short-term property — pressure-treated makes sense if you'll be moving in 5–10 years.
