If you’re building a wood fence in the Pacific Northwest, you’ll likely choose between two materials: cedar and pressure-treated lumber. Both are real wood, both can be built in the same styles, but they perform very differently in this climate.
At New Ridge Fencing LLC, we’ve installed hundreds of wood fences across Woodinville, Kirkland, Bothell, and the surrounding area over the past 11+ years. We’ve seen how both materials hold up in Washington’s rain, moisture, and freeze-thaw cycles. Here’s what we’ve learned.

Cedar: The Pacific Northwest Standard
Cedar is the most popular fence material in Western Washington, and there’s a reason for that. It contains natural oils that resist rot, decay, and insect damage without chemical treatment. In a region where it rains 150+ days a year, that natural resistance matters.
A well-built cedar fence typically lasts 15 to 25 years in the Pacific Northwest with basic maintenance. It weathers to a silver-gray if left untreated, or it can be stained to maintain its warm, natural color. Either way, it looks at home in this landscape.
Cedar is also lighter than pressure-treated lumber, which makes it easier to work with and puts less stress on posts and rails over time.
Pressure-Treated Wood: Lower Cost, Shorter Life
Pressure-treated lumber is infused with chemical preservatives to resist rot and insects. It costs less per board than cedar, which makes it attractive on a budget. But in the Pacific Northwest, it has drawbacks.
Pressure-treated wood tends to warp, twist, and check (crack) more than cedar as it dries out and absorbs moisture repeatedly. In our climate, that cycle happens constantly. Fences built with pressure-treated lumber often start showing these issues within a few years.
It also requires staining or sealing to look good, and that maintenance needs to happen regularly. Left untreated, it turns a dull gray-green that most homeowners don’t find appealing.
Side-by-Side Comparison
| Factor | Cedar | Pressure-Treated |
|---|---|---|
| Natural rot resistance | Yes | No (chemical treatment) |
| Typical lifespan (PNW) | 15–25 years | 10–15 years |
| Warping/checking | Minimal | Common |
| Maintenance needed | Optional staining | Regular staining/sealing |
| Appearance over time | Weathers to silver-gray | Turns dull gray-green |
| Weight | Lighter | Heavier |
| Upfront cost | Higher | Lower |
Which Should You Choose?
For most homeowners in the Pacific Northwest, cedar is the better long-term investment. It lasts longer, looks better, requires less maintenance, and performs well in our wet climate without chemical treatment.
Pressure-treated wood makes sense if budget is the primary concern and you’re willing to commit to regular maintenance. But over 15–20 years, the total cost of ownership — including staining, repairs, and earlier replacement — often makes cedar the more economical choice.
If you’re weighing cedar against other materials entirely, see our comparisons: vinyl vs. wood and chain link vs. wood.
