DIY Wooden Fence Cost Calculator in Washington
If you are building your own fence in Washington, the climate makes material choice a bigger deal than the average DIY project. Putting together a 150 linear ft, 6 ft privacy fence, material costs come to roughly $1,550–$3,100 for pressure-treated pine, $3,100–$5,200 for cedar, or $4,700–$7,200+ for redwood. In much of the state, long wet seasons mean wood fences stay damp for extended periods, which is hard on untreated or lightly protected lumber. Cedar and redwood are often the smart picks because they handle constant moisture better and usually demand less maintenance than budget pine.
Washington is also a place where hiring a professional tends to cost more than average, so the savings from doing the fence installation yourself can be noticeably stronger here. Even so, do not skip the planning stage. Check local permit requirements and any HOA rules before you buy materials, especially on corner lots or where visibility matters. If your yard has roots, slopes, or stubborn soil, an auger rental can save time. State sales tax adds a noticeable bump at checkout, but the DIY labor savings often more than offset that.

Frequently Asked Questions
What fence material holds up best in western Washington's rainy climate?
Western Washington's long wet season and persistent moisture make rot resistance the top priority. Cedar is the best natural-wood choice because it holds up far better than PT pine in repeated wet-dry cycling and shaded, damp conditions. Vinyl is also a strong option, with no moisture absorption and no refinishing requirement. In any wood fence, ground-contact rated posts and sealing cut ends matter significantly more in western Washington than in drier states.
What hardware should I use for a fence in Washington's wet climate?
Use hot-dipped galvanized or stainless steel hardware, especially in western Washington and any area near Puget Sound. Washington's wet climate corrodes ordinary zinc-plated fasteners and brackets faster than many homeowners expect, and the problem is even worse in salt-air-influenced coastal areas. Spending more upfront on corrosion-resistant hardware prevents loose rails, rust stains, and early hardware failure.
