About this calculator
Deck staining cost depends on square footage, the condition of the existing wood (which drives prep labor like power washing, sanding, and old-stain stripping), and the stain type chosen — solid, semi-transparent, or clear/toner finishes all have different material costs and coverage rates. 2026 US national averages run roughly $1-$2 per sq ft for stain material and $1.50-$3.50 per sq ft for professional application labor, with heavily weathered decks needing stripping or sanding adding $0.75-$1.50 per sq ft in prep labor. A typical 300 sq ft deck therefore runs $750-$1,800 professionally stained depending on condition and stain quality. This calculator totals stain material, prep labor, and application labor by square footage so you can benchmark a painter's quote; railings and stairs typically add 15-25% more surface area than the deck floor alone, so measure carefully or use the railing multiplier included here.
Worked example
Using the values the calculator loads with:
Inputs
- Deck floor area: 300 sq ft
- Stain material rate: 1.4 $/sq ft
- Prep (wash/sand/strip) rate: 1 $/sq ft
- Application labor rate: 2.25 $/sq ft
- Railing/stairs surface add-on: 20 %
Results
- Total staining cost: $1,674
- Prep & cleaning labor: $360
- All-in cost per sq ft (deck area): $5.58
What each field means
Inputs
- Deck floor area (sq ft)
- The deck floor area used in the calculation, measured in sq ft. Starts at 300 sq ft so you have a working example on load. Accepted range: 50–2000 sq ft.
- Stain material rate ($/sq ft)
- The stain material rate used in the calculation, measured in $/sq ft. Starts at 1.4 $/sq ft so you have a working example on load. Accepted range: 0.5–3 $/sq ft.
- Prep (wash/sand/strip) rate ($/sq ft)
- The prep (wash/sand/strip) rate used in the calculation, measured in $/sq ft. Starts at 1 $/sq ft so you have a working example on load. Accepted range: 0–2.5 $/sq ft.
- Application labor rate ($/sq ft)
- The application labor rate used in the calculation, measured in $/sq ft. Starts at 2.25 $/sq ft so you have a working example on load. Accepted range: 0.5–5 $/sq ft.
- Railing/stairs surface add-on (%)
- The railing/stairs surface add-on used in the calculation, measured in %. Starts at 20 % so you have a working example on load. Accepted range: 0–50 %.

FAQ
Solid, semi-transparent, or clear stain — which costs more?
Solid stains cost slightly more per gallon and hide wood grain but last longest (3-5 years); semi-transparent shows grain and lasts 2-3 years; clear/toner finishes are cheapest per gallon but need reapplication almost yearly, often making them costlier over time.
How much does old stain removal add to the cost?
Stripping old solid stain to bare wood before restaining can add $1-$2 per sq ft in labor and is one of the most time-consuming parts of a deck refresh — it's often why switching from solid back to semi-transparent stain costs more than staying with the same finish type.
How often should a deck be restained?
Semi-transparent stains typically need reapplication every 2-3 years, solid stains every 3-5 years, and high-traffic or sun-exposed decks on the shorter end of those ranges regardless of stain type.
Does weather affect staining cost or timing?
Yes — stain needs 48-72 hours of dry weather above roughly 50°F to cure properly, so scheduling around a clear weather window is essential and rescheduling due to rain is a common reason contractors build buffer days into quotes.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
