Pressure washing a pool deck typically costs $150-$600, with many homeowners paying about $325 for a standard-size deck. Total price depends on square footage, surface material, buildup, access, and whether the quote includes chemicals, furniture moving, or sealing.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Pool deck wash | $150 | $325 | $600 | Typical residential cleaning |
| Price per square foot | $0.20 | $0.35 | $0.60 | Higher for delicate or heavily stained surfaces |
| Small deck, 300 sq ft | $100 | $150 | $250 | Minimum service charges may apply |
| Large deck, 1,000 sq ft | $250 | $350 | $600 | Price varies with layout and soil level |
Typical prices for a 300- to 1,000-square-foot pool deck
Most contractors charge around $0.20-$0.60 per square foot, or set a minimum visit price of roughly $100-$200. A 500-square-foot concrete deck with ordinary dirt and algae may cost $150-$300; a 1,000-square-foot deck with more detailed rinsing can reach $300-$600.
For a typical 500-square-foot concrete deck, a practical budget is $175-$350. These ranges assume standard residential access and a basic wash, not stain removal, sealing, or extensive furniture handling.
Assumptions: U.S. residential contractor rates, standard equipment, accessible deck, and no major repairs.
What pool-deck washing quotes include
A basic quote generally covers setup, pressure or surface-cleaner operation, and rinsing. Some providers price separately for detergent, moving patio furniture, protecting nearby landscaping, or treating stubborn organic growth. Ask whether the estimate covers the full deck perimeter, steps, coping, and connected walkways.
| Quote component | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Labor | $75 | $150 | $300 | 1-3 hours on site |
| Cleaning solution | $10 | $30 | $75 | Algae or mildew treatment |
| Equipment and setup | $15 | $35 | $75 | Washer, surface cleaner, hoses |
| Furniture moving | $0 | $35 | $100 | Depends on amount and access |
| Wastewater control | $0 | $25 | $100 | May apply where runoff must be managed |
Contractors may bundle these charges into a flat rate rather than itemize them. For labor-only estimates, 1-3 hours at about $50-$100 per hour equals $50-$300 before supplies, travel, and minimum charges.
How deck size, surface, and algae change the rate
Square footage is the starting point, but material changes the cleaning method. Broom-finished concrete is usually less costly than textured pavers or natural stone, which can require lower pressure and more careful work. Wood and composite surfaces also need conservative pressure settings to avoid damage.
Heavy algae, embedded grime, or rust can add about $50-$200, depending on how much chemical treatment and repeat cleaning are needed. A deck larger than 1,000 square feet may earn a lower per-square-foot rate, while a very small job can still incur a minimum charge.
Surface condition and material can shift a quote by $100 or more, even when two decks have similar dimensions. Provide the contractor with the deck material, approximate area, and photos of stains for a more useful estimate.
How to lower the pool-deck washing bill
Measure the deck before requesting quotes, and identify whether the price includes steps, coping, and adjoining walkways. Clear furniture and toys in advance if the provider charges for moving them. Comparing at least three written estimates helps reveal differences in included area, treatment, and cleanup.
Keeping the job to a basic wash is usually the clearest way to control cost. Avoid adding sealing or specialty stain treatment unless the surface needs it; those services are separate projects and can substantially increase the bill. Do not select a low quote without checking that the contractor will use pressure appropriate for the deck material.
Regional pool-deck rates from Florida to the Northeast
Labor and travel costs can make quotes differ by location. In lower-cost rural markets, basic washing may run 10%-20% below the national middle range. Large metropolitan areas and high-demand coastal markets may be 15%-30% higher, particularly where contractor minimums and travel charges are common.
Warm, humid regions may have frequent algae buildup and strong seasonal demand before summer. In colder areas, spring cleaning can bring a rush of requests after winter. These are broad comparisons, not fixed regional prices; local quotes depend on competition, access, and deck condition.
How long a 500-square-foot deck takes to wash
A straightforward 500-square-foot concrete deck often takes about 1-2 hours of cleaning, plus setup and rinsing. A two-person crew may finish faster but can cost more per hour; many companies instead quote a flat job price. Furniture, narrow access, multiple levels, or delicate surfaces can add 30-90 minutes.
Ask whether the contractor expects the pool to be covered or protected and whether the customer must move furniture beforehand. Clear access and an outdoor water connection can reduce delays, though some providers bring their own water or charge for extra setup.
When detergent, stain treatment, or sealing costs extra
Light detergent application may be included, but dedicated algae or mildew treatment commonly adds $25-$100. Spot treatment for rust or other stubborn stains can add $50-$200, depending on the affected area and product. Sealing is not part of pressure washing; professional deck sealing may cost roughly $1-$3 per square foot, with material and surface preparation affecting the rate.
Confirm that any chemical is suitable for the deck material and safe to use near pool water, landscaping, and metal fixtures. A contractor may need to control runoff or rinse carefully, especially where cleaning solution could enter the pool.
Pressure washing versus soft washing for delicate decks
High pressure is not appropriate for every pool deck. Soft washing uses lower pressure and cleaning solution, and may be recommended for surfaces that could etch, splinter, or lose joint sand. Its price can be similar to standard washing or about 10%-25% higher when treatment and extra rinsing are included.
For concrete with ordinary surface dirt, standard washing is often the lower-cost choice. For wood, older pavers, or fragile stone, the least expensive method is not necessarily the safest. Ask for the planned pressure or method and whether the quote includes a test area.
