Deck Staining Cost Calculator
Staining and sealing your deck protects the wood and extends its life dramatically. This estimates cost by deck area and finish type — sealer, semi-transparent, or solid stain.
Finish tier drives price: clear sealer ≈$0.70-1.20/sq ft, semi-transparent ≈$1.25-2.10/sq ft, solid stain ≈$1.85-3.25/sq ft in 2026 examples. Prep is half the job: cleaning, sanding, and dry wood are what make stain last. Regional: 0.85× rural to 1.35× metro. Maintenance: re-stain every 1-3 years depending on exposure; a deck left bare cracks and splinters far faster than it costs to maintain.
FAQ
How much does it cost to stain a deck?
About $0.70-$3.25 per square foot in 2026 examples depending on finish — a 300 sq ft deck runs $210-$555 professionally, or $50-$150 for DIY materials.
Semi-transparent or solid stain?
Semi-transparent shows the wood grain and lasts 2-3 years; solid stain is paint-like, hides flaws, and lasts longer (3-5 years) but hides the wood. Choose solid if the deck is weathered; semi-transparent if you want the wood look.
How often should I re-stain my deck?
Every 1-3 years depending on climate, sun exposure, and finish. The water-bead test is the signal: when water soaks into the wood instead of beading, it's time to re-stain before the wood degrades.
