Your 100-Foot Wood Privacy Shopping List
The most popular residential fence. 6-foot tall boards mounted side-by-side for full privacy. Uses pressure-treated 4×4 posts and 1×6 or 1×4 dog-ear pickets.
At 8-foot spacing, 100 feet divides into 13 sections. That means 14 line and end posts, plus 2 gate posts if you add a walk gate, for 16 posts total. Each post takes 2 bags of 60 lb concrete, so buy 32 bags. With 3 rails per section you need 39 rails.
Doing it yourself, material cost is about $1,500–$2,500. Hiring a contractor typically adds $5–$15 per foot in labor, or about $500–$1,500 for this length, for an installed total near $2,000–$4,000. Prices vary by region, so treat these as planning numbers.
