Professional deck staining runs about $2 to $5 per square foot, or roughly $500 to $1,500 for an average 300–500 square foot deck. That usually covers cleaning, light sanding, and one to two coats. The price lands where it does based on three things: deck size, how much prep and stripping the wood needs, and whether railings and stairs are part of the job.
Here's a clear cost breakdown, the difference between stain and sealer, how often to restain, and an honest take on when a weekend of DIY beats hiring a pro and when it doesn't.
A deck in decent shape: clean, light sand, one to two coats of stain on the boards. The most common job, and where most average decks land.
A weathered or previously coated deck that needs stripping, sanding, or two-tone work. Prep is most of the labor, so this is where the top of the range comes from.
Spindles, balusters, and stairs are slow detail work and usually priced as an add-on or a higher per-foot rate. A deck with lots of railing costs more than its square footage suggests.
Deck staining is one of the more DIY-friendly outdoor projects. A homeowner can do a small, single-level deck for $50 to $200 in materials plus a weekend. The application is straightforward; the part people underestimate is prep — proper cleaning, full drying time, and even coats are what separate a finish that lasts three years from one that blotches and peels by next summer.
Hire a pro for large or two-story decks, anything that needs stripping, or when you want a flawless, long-lasting result without spending the weekend on your knees. And restain on schedule — every 2 to 3 years, sooner in full sun. Letting the boards gray and crack turns a $1,000 stain job into a board-replacement bill.
