Cedar vs Redwood Fence: Which Lasts Longer in San Jose?

If you are building a wood fence in the South Bay, the first big decision is almost always cedar versus redwood. Both are beautiful, both resist rot and insects naturally — but they are not interchangeable. Here is how they actually compare in our climate.

Why Both Beat Standard Pine

Standard pressure-treated pine is cheap, but it twists, warps, and checks badly in our dry summers. Cedar and redwood contain natural oils and tannins that make them resistant to rot, decay, and termites without chemical treatment. That natural resistance is why both are the default choice for quality South Bay fences.

Redwood: The Longevity Champion

Redwood is the denser, tighter-grained of the two. Its higher oil and tannin content gives it a slight edge in rot resistance, which is why a well-built redwood fence in the Bay Area routinely lasts 25 to 30 years. It holds stain longer, resists warping better, and stays straighter over time.

The trade-off is cost. Redwood is consistently 20 to 40 percent more expensive than cedar for the same fence. For a long property line, that difference adds up fast.

Cedar: The Value Option That Still Delivers

Western red cedar is lighter and softer, which makes it easier to work with and less expensive. In our dry Mediterranean climate, a properly built cedar fence lasts 15 to 20 years without much trouble. That is more than enough for most homeowners, especially if you plan to move within a decade or two.

Cedar is also the better choice when you want to apply a stain — it accepts penetrating oil stains more evenly than redwood, giving you a more consistent finish. If you love the look of a dark or semi-transparent stain, cedar is often the smarter pick.

The Climate Factor

Most of the longevity advice online assumes wet, humid climates where rot is a constant threat. In San Jose, our real enemy is the sun and dry heat, not standing water. That means both woods age more gracefully here — and the gap between redwood and cedar narrows considerably. Unless your fence sits in a permanently damp, sprinkler-soaked zone, cedar performs nearly as well as redwood for a noticeably lower price.

How to Decide

• Choose redwood if you want maximum lifespan, plan to stay 20+ years, and are okay spending more upfront.
• Choose cedar if you want great value, prefer a stained finish, or expect to move within 10 to 15 years.
• Either works in most San Jose backyards — the quality of the install matters more than the species.

The honest truth is that a poorly built redwood fence will fail faster than a well-built cedar one. Post depth, concrete footing, rail spacing, and hardware all matter more than the species on the tag. That is why we walk you through the options and build to last regardless of what you pick.
