Wood Fence Installation in Washington: Cedar Options, Posts, Gates & PNW Weather Considerations
Your guide to building a beautiful, long-lasting wood fence in the Pacific Northwest
Why Cedar Dominates PNW Fencing
In Washington state, Western Red Cedar isn't just a preference—it's practically the standard. Our wet climate demands naturally rot-resistant wood, and cedar has been protecting Northwest properties for generations. It contains natural oils (thujaplicins) that repel insects and resist decay without chemical treatment.
Other wood options exist, but none match cedar's combination of durability, beauty, and local availability. This guide covers costs, installation best practices, and how to make your fence last decades in our challenging climate.

Wood Options for Washington Fences
Western Red Cedar (Recommended)
Pros:
- Naturally rot and insect resistant
- Beautiful grain and color
- Locally sourced (Pacific Northwest)
- Weathers to attractive silver-gray
- Lightweight, easy to work
- Sustainable (replanted forests)
Cons:
- Higher cost than treated lumber
- Requires maintenance for color retention
- Quality varies by grade
- Softer wood (can dent)
Grades:
| Grade | Description | Cost | Best For |
|---|---|---|---|
| Clear/CVG | No knots, premium appearance | $$$ | High-visibility fences |
| Tight-knot | Small, tight knots | $$ | Most residential fencing |
| #2 Common | Larger knots, some defects | $ | Budget projects, painted fences |
Pressure-Treated Lumber
Pros:
- Lower initial cost
- Widely available
- Durable when maintained
Cons:
- Contains chemicals (newer treatments safer)
- Prone to warping and checking
- Requires staining/sealing
- Not as attractive as cedar
- Shorter lifespan in wet conditions
Washington reality: Pressure-treated fences can work, but require more maintenance and typically last 15-20 years vs. 20-30+ for cedar.
Redwood
Pros:
- Beautiful appearance
- Naturally rot-resistant
- Excellent durability
Cons:
- Very expensive
- Less available in WA
- Environmental concerns
Note: Rarely used in Washington due to cost and availability. Cedar provides similar performance locally.

Installation Best Practices for WA Climate
Protecting Posts from Rot

- Slope concrete cap: Water runs away from post
- Treat cut ends: Apply wood preservative to cuts
- Consider steel posts: Wood sleeve over steel core
Preventing Fence Failure
| Problem | Prevention |
|---|---|
| Post rot | Brackets, proper drainage |
| Wind damage | Proper post depth, spacing |
| Gate sag | Strong posts, corner bracing |
| Warping | Quality lumber, proper fasteners |
| Moss/algae | Annual cleaning, trim vegetation |
Fastener Selection
| Fastener | Durability | Cost | Notes |
|---|---|---|---|
| Galvanized nails | Fair | $ | Will rust eventually |
| Hot-dipped galvanized screws | Good | $$ | Better than electro-galv |
| Stainless steel | Excellent | $$$ | Best for coastal/wet areas |
| Ceramic-coated | Very good | $$ | Good balance |
⚠️ Warning: Standard screws and nails will rust in Washington, staining cedar. Use hot-dipped galvanized or better.
Maintenance for Washington Climate
