Cost to Deck Staining and Sealing in Portland, OR (2026)
If you’re budgeting a deck staining and sealing in Portland, most projects run $347-$2,080, 16% above the $800 national average. What moves that number most is usually one thing: Deck Size. On its own it can swing the cost by $1-$4/sq ft, so that’s the decision to slow down on before you sweat the smaller stuff.
