Linear feet vs square feet — and why the calc uses sqft
Some pros price fence work per linear foot ($1–$3 per linear foot for typical 6-foot fence); others price per square foot ($0.30–$0.80). They're the same number expressed differently: a 6-foot fence at $0.50/sqft = $3/linear foot. The calculator uses sqft because that's how the underlying pricing engine handles all surfaces — multiply fence height × linear feet to convert. For an 8-foot privacy fence, count the full 8-foot height.
Wood vs vinyl vs composite vs chain link
Wood (cedar, pine, pressure-treated) is the most common and most expensive to wash properly — soft graying and mildew need careful PSI and chemistry. Vinyl washes the fastest and benefits from a mild bleach solution to remove the chalky oxidation that gray vinyl develops. Composite fences (Trex Seclusions, SimTek) wash similarly to vinyl. Chain-link rarely needs pressure washing — if rust is the issue, the link itself usually needs replacement, not cleaning.
One-sided vs two-sided pricing
"Visible surface" usually means one side. If you need both sides washed (your side and the neighbor's side, which is a courtesy job), expect to roughly double the quote — operators charge per surface, not per fence. Most quotes assume one-sided unless you specify otherwise. If you share a fence with a neighbor who's also having theirs washed, see if the operator will discount the back-to-back work.
Stain prep (the most common reason for a wash)
Like decks, fences are typically washed as prep for staining or sealing. Stain doesn't bond to dirty, graying wood, and a fresh stain over old buildup peels within 12 months. Plan to wash, let the wood dry 48–72 hours, then stain or seal. The wash + stain sequence is the dominant maintenance cycle for wood privacy fences in the South and Southeast.
Regional cost-of-living impact
Fence washing labor scales with regional cost of living, same as every other surface. A 600 sqft wood fence at standard intensity costs roughly $285 in Atlanta (0.95× multiplier), $405 in San Francisco (1.35×), and $420 in Manhattan ZIP 100xx (1.40×).
