A wood privacy fence adds security, curb appeal, and property-line definition to your home. This estimate covers setting pressure-treated or cedar posts in concrete, attaching horizontal rails, and installing dog-ear or board-on-board pickets. In NorCal, redwood and cedar are the preferred species because they naturally resist rot and termites in our Mediterranean climate. The estimate scales by linear feet of fence line.

NorCal's dry summers and wet winters cause wood to expand and contract. Use kiln-dried lumber and apply sealant within 60 days of installation.

Cotati is located in Sonoma County (Wine Country). Small bohemian town near Sonoma State University. The local utility provider is PG&E.

Wood Privacy Fence Installation in Cotati — FAQ

How long does a cedar privacy fence last in NorCal?+

With proper maintenance (sealing every 2–3 years), a cedar fence in the Sacramento Valley typically lasts 15–25 years.

Do I need a permit for a 6-foot fence?+

Most NorCal cities allow a 6-foot backyard fence without a permit, but front-yard fences over 3–4 feet usually require one. Check with your local planning department.

What is the difference between dog-ear and board-on-board?+

Dog-ear fences have pickets side by side with visible gaps when the wood shrinks. Board-on-board overlaps pickets for complete privacy and costs about 15–20% more in materials.

Should I use redwood or cedar?+

Both resist rot naturally. Redwood is more readily available in NorCal and often slightly cheaper locally. Cedar has a tighter grain and can be more uniform in appearance.
