Pressure washing and staining a deck typically costs $450-$1,350 for a 300-square-foot deck, with a national planning average near $850. Total price depends on deck size, condition, railings, stain quality, access, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Wash and stain, 300 sq. ft. | $450 | $850 | $1,350 | Includes standard prep and one stain coat |
| Combined service per sq. ft. | $1.50 | $2.85 | $4.50 | Higher for heavy prep or difficult access |
| Pressure washing only | $75 | $175 | $350 | Often subject to a minimum charge |
| Stain and application | $1.00/sq. ft. | $2.00/sq. ft. | $3.75/sq. ft. | Varies by product and surface condition |
What homeowners pay to wash and stain a 300-square-foot deck
For a standard, ground-level 300-square-foot wood deck, contractors commonly quote $450-$1,350 for washing, routine preparation, and staining. The average job is about $850, assuming ordinary access, no major repairs, and a midrange stain. A small deck may still cost $250-$500 because many companies have minimum service charges.
A useful budget range is $1.50-$4.50 per square foot for the combined work. Prices generally include labor and stain, but may exclude extensive sanding, stripping, railing details, or board replacement. Assumptions: U.S. midrange labor rates, common wood decking, normal access, and one stain coat.
How washing, sanding, and stain shape the deck quote
Quotes may bundle several tasks or list them separately. Washing removes dirt and some surface growth; it does not automatically remove old stain. Sanding or chemical stripping can add substantial labor when a coating is peeling or incompatible with the new product.
| Quote component | Typical price | What changes the charge | Common scope |
|---|---|---|---|
| Pressure washing | $0.25-$0.75 per sq. ft. | Soil, algae, setup, water access | Low-pressure cleaning and rinse |
| Sanding or stripping | $0.50-$2.00 per sq. ft. | Old coating, surface damage, detail work | Extra prep beyond routine cleaning |
| Stain and supplies | $0.35-$1.25 per sq. ft. | Product type and number of coats | Stain, brushes, rollers, masking |
| Application labor | $0.75-$2.00 per sq. ft. | Rails, stairs, access, drying schedule | Applying stain to deck surfaces |
| Minor repairs | $75-$500 per job | Loose fasteners or damaged boards | Usually priced outside basic service |
Ask whether the quote includes sanding, stain, railings, and a second coat. One contractor may include routine prep in the total, while another may price each task as an add-on.
Which deck size and condition change the per-square-foot rate
Size affects both the total and the rate. A deck under 150 square feet may have a higher per-square-foot price because setup and cleanup take a similar amount of time as on a larger project. Decks over 500 square feet can sometimes receive a lower unit rate, provided their layout is straightforward.
Condition is another major cost driver. Light surface dirt usually needs washing and drying; gray, weathered boards may need sanding. Removing a failing film-forming coating can add $0.50-$2.00 per square foot. Railings, lattice, and stairs also take longer than open deck boards, often adding $100-$500 depending on quantity and detail.
Expect a higher quote when the job requires coating removal, multiple coats, or detailed railing work. A deck more than 6 feet above ground, a steep stair run, or limited hose access can also increase setup time and safety requirements.
How many labor hours does deck washing and staining take?
A two-person crew may spend 4-8 labor hours on a straightforward 300-square-foot deck, divided across cleaning, preparation, and application. The work may stretch over two or three calendar days because the wood must dry before staining; rain or high humidity can extend that wait. Typical contractor labor rates are about $50-$100 per worker-hour, though many companies sell the job at a flat rate.
Washing too aggressively can damage soft wood or force water into joints, so professional pricing should account for suitable pressure and nozzle selection. Stain also needs the product’s specified temperature and drying conditions. Calendar time is often longer than hands-on time because drying determines when the next step can begin.
Three deck quotes show low, typical, and high scopes
These examples illustrate how condition and detailing change the total for similarly sized decks. They assume a 300-square-foot surface and are not guaranteed local rates.
| Example | Scope and labor | Unit estimate | Total |
|---|---|---|---|
| Basic ground-level deck | Wash, light prep, one coat; 6 crew-hours | $1.75 per sq. ft. | $525 |
| Typical deck with rails | Wash, spot sanding, one coat; 10 crew-hours | $2.85 per sq. ft. | $855 |
| Weathered raised deck | Wash, substantial sanding, rails, two coats; 18 crew-hours | $4.50 per sq. ft. | $1,350 |
The high example costs more because it includes extra preparation and detailed surfaces, not simply a higher stain price. Confirm whether labor-hour figures describe crew time or combined worker-hours, since two people working five hours equal 10 worker-hours.
Regional deck staining rates from urban to rural markets
Local wages and contractor availability can shift a quote from the national planning range. In lower-cost rural markets, a comparable job may run about 10%-20% below a national midpoint. Major metro areas and high-cost coastal markets may be 15%-35% above it, especially where access, parking, or scheduling is difficult.
For a $850 typical project, those differences suggest roughly $680-$765 in a lower-cost market and $980-$1,150 in a high-cost metro. These are comparison estimates, not fixed regional prices; wood condition and scope can outweigh location. Compare at least two itemized local quotes using the same square footage and prep requirements.
Ways to lower the wash-and-stain bill without skipping prep
Clear furniture, planters, and grills before the crew arrives, and trim plants that block access if the contractor allows it. These steps reduce setup time, but the contractor should handle surface cleaning and determine whether sanding or stripping is needed. Scheduling in a dry, moderate-weather period may also avoid delays that require extra visits.
Keep the scope focused: stain the deck floor and essential rails rather than adding unrelated fences or structures, and compare a one-coat product with a two-coat system only when both meet the manufacturer’s requirements. Avoid choosing solely by the lowest total; a quote that omits prep may cost more after peeling or uneven coverage appears. Request the same written scope from each bidder, including cleaning method, prep, product, coats, and excluded repairs.
