Material choice determines cost, maintenance, and lifespanWood privacy fencing costs $1,900–$3,150 per linear foot installed in Seattle — natural look but requires staining or painting every 3–5 years. Vinyl fencing costs $2,250–$5,370 per linear foot — maintenance-free but may warp in extreme heat. Aluminum and chain link are the most affordable options at $760–$1,800 per foot. In Seattle, frequent rain directly affects how quickly wood materials degrade.
Linear footage determines total cost — measure firstFence pricing is always per linear foot. Before getting quotes, measure your property perimeter accurately — GPS property surveys (from your deed or county GIS) are more reliable than measuring by eye. Every 100 linear feet of fencing adds $450–$895 to the total depending on material. Know your exact footage before accepting any bid.
Existing fence removal is a separate costRemoving and disposing of an existing fence adds $3–$8 per linear foot to your project. For a 200-foot perimeter, that's $600–$1,600 in additional cost. Some contractors include this in their bid; others quote fencing installation only. Confirm explicitly whether removal and haul-away are included — this is one of the most common sources of "surprise" costs on fence projects.
Post depth and concrete are where quality divergesFence posts must be set 1/3 of their total length below grade (minimum 2 feet) and anchored in concrete. Posts not set deep enough will lean within 2–3 years, especially in Seattle where mild but wet causes freeze-thaw cycles or saturated soil. Ask specifically: what depth are posts being set? Are they set in concrete or compacted gravel? These details separate professional installs from failures.
Permit and property line requirementsMost Seattle municipalities require a permit for fence installation and have rules about fence height (typically 4 ft front yard, 6 ft rear yard) and setback from the property line. Building a fence on a disputed property line or without a permit can result in forced removal at your cost. Confirm your property lines using a plat survey before installation — not just a tape measure from your house.
Gates add cost disproportionate to their sizeA single gate adds $200–$600 to your fence project; a double drive gate for vehicle access adds $500–$1,500+. Gate hardware quality matters significantly — cheap hinges and latches fail within 2–3 years in Seattle's frequent rain. Confirm what hardware brand is included and whether the gate posts are being set deeper (they should be — gates exert more lateral stress than fence panels).
