How to Price a Deck Staining Job
Deck staining typically runs $1–$3 per square foot including prep, or $300–$600 for an average 200–300 sq ft deck, rising toward $1,000+ for larger decks or heavy prep work. Stripping old stain, sanding, and power washing are usually priced as their own line rather than folded into the stain application, and railings or spindles add real labor time that a flat per-square-foot deck-surface number doesn't capture.
Base pricing: per square foot
$1–$3 per square foot, including standard prep, is the common range for deck staining. That puts a typical 200–300 sq ft deck at $300–$600, with larger decks or heavier prep pushing well past $1,000.
The spread inside that range comes down to condition — a deck that’s never been stained and needs stripping and sanding sits at the top of it, even at the same square footage as a deck that just needs a clean and a coat.
What isn’t in the flat surface rate
Three things regularly take longer than the deck surface itself:
- Stripping old stain. Removing a failed prior coat is slower than sanding bare wood and should be quoted as its own line once you’ve seen it.
- Railings and spindles. Dozens of individual spindles take far longer per square foot than the open deck surface — price them separately.
- Power washing. Cleaning before staining is a standard step, but a deck with mildew or heavy buildup takes longer than a quick rinse.
Two coats change the math
A stain that needs two coats roughly doubles the application time, not the material cost. Semi-transparent and oil-based stains often call for it; solid stains usually don’t. Quote based on the product you’re actually using, not a generic “deck staining” number that assumes one coat.
Put the breakdown on the invoice
Even when the estimate is one flat number, keep prep, staining, and railings/spindles as separate lines on the invoice. It’s the record that explains the total if a customer compares it to a smaller job, and it’s your own reference the next time this deck needs a re-coat.
Frequently asked questions
Does the price change based on stain type?
Yes. Solid stain covers more evenly in one coat and is cheaper to apply; semi-transparent and oil-based stains often need two coats and more careful application, which adds labor time even at the same square footage.
Should railings and spindles be priced separately?
Yes, always. A railing with dozens of spindles takes far longer per square foot than the flat deck surface, and pricing it into the same per-square-foot number underprices every deck with a full railing system.
How much should prep work add to the price?
Stripping old stain and heavy sanding can add as much time as the staining itself on a neglected deck — quote prep as its own line once you've seen the deck's condition, not as part of the flat stain rate.
