Concrete cleaning typically costs $0.15-$0.60 per square foot, with many standard jobs landing near $0.30 per square foot. The final price depends on surface area, stains, cleaning method, access, and whether sealing or other prep work is included.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic pressure washing | $0.15/sq ft | $0.30/sq ft | $0.60/sq ft | Routine dirt on accessible concrete |
| 400-sq-ft driveway | $60 | $120 | $240 | May be subject to a minimum charge |
| Oil or rust stain treatment | $0.25/sq ft | $0.55/sq ft | $1.25/sq ft | Spot treatment or added dwell time |
| Cleaning plus sealing | $0.75/sq ft | $1.50/sq ft | $3.00/sq ft | Includes a sealer allowance |
What a Typical Driveway or Patio Cleaning Costs
For a standard residential job, basic pressure washing generally runs $0.15-$0.60 per square foot, or about $150-$600 for 1,000 square feet. A practical budget average is roughly $300 for that area when the concrete has ordinary dirt and algae but no extensive oil contamination. Contractors may price small jobs by a minimum service fee instead of the measured area.
Most quotes cover washing only, not stain removal, repairs, or sealing. A 500-square-foot patio with good access may cost $75-$300, while a larger 1,500-square-foot driveway and walkway may cost $225-$900. Assumptions: U.S. residential rates, standard pressure washing, normal access, and no major repair work.
How Labor, Detergent, and Equipment Shape the Quote
Cleaning quotes combine labor, equipment operation, cleaning agents, travel, and business overhead. Labor is often the largest direct component; a crew may charge an effective $50-$100 per worker-hour, depending on local wages and the job. A contractor’s minimum visit charge can make a small walkway cost more per square foot than a broad driveway.
| Quote component | Typical allowance | What changes the charge | Common pricing basis |
|---|---|---|---|
| Labor | $50-$100 per worker-hour | Stain work, edges, furniture moving | Hourly or included |
| Pressure washer and surface cleaner | $25-$100 per job | Equipment size and setup | Included or equipment fee |
| Detergent or degreaser | $10-$75 per job | Oil, algae, or grease treatment | Per job or treated area |
| Travel and overhead | $25-$100 per visit | Distance and minimum charge | Flat fee or included |
| Wastewater handling | $0.05-$0.30 per sq ft | Local rules and runoff controls | Per area or job |
Ask whether the quoted total includes pretreatment and wastewater controls. For example, three crew-hours at $70 per worker-hour represent $210 in labor before chemicals, equipment, travel, and other charges.
Why Surface Size and Stain Depth Change the Price
Area affects total cost, but not always the per-square-foot rate: jobs under roughly 200-300 square feet may incur a $75-$175 minimum. Larger open surfaces can receive lower unit pricing because setup time is spread over more concrete. Many estimates use measured square footage, while others quote a flat driveway or patio rate.
Stain severity is another major variable. Light dirt and surface algae may fit the basic rate; oil, tire marks, rust, or embedded grease can add $0.10-$0.75 per square foot, or be billed as a $25-$150 spot-treatment charge. Concrete that has not been maintained for years may need slower passes or repeat applications.
Surface condition and access can matter as much as square footage. A narrow side yard, steep slope, long hose run, or limited water supply can add $25-$150. Delicate or damaged concrete may need lower pressure and more hand treatment, which takes longer than using a surface-cleaner attachment on sound pavement.
When Sealing or Stain Removal Adds to the Bill
Degreasing, rust treatment, and chewing-gum removal are often separate services. Allow $25-$100 for a few isolated spots or $0.25-$1.25 per square foot for widespread staining. Results depend on stain age and concrete porosity; a cleaning quote should not promise that old oil marks will disappear completely.
Concrete sealing after washing commonly adds about $0.60-$2.40 per square foot, including typical material and application labor. Combined cleaning and sealing may therefore reach $0.75-$3.00 per square foot. Sealer type, coats, surface preparation, and drying time affect the price. Repairs such as crack filling are usually quoted separately.
Confirm that the surface will be dry enough for sealer application before accepting a combined price. Rain, shade, humidity, or limited scheduling can extend the wait between washing and sealing. Removal of furniture, planters, or vehicles may also be excluded or billed separately.
How U.S. Location and Water Rules Affect Cleaning Rates
Local labor costs and business travel produce meaningful regional variation. In high-cost metropolitan areas, routine residential cleaning can run 15%-35% above a national middle estimate; small towns and rural areas may be 10%-20% below it, though long travel distances can cancel the savings. These are budgeting differences, not fixed regional tariffs.
Some locations restrict detergent runoff into storm drains or require wastewater recovery for commercial sites. Containment or recovery can add $0.05-$0.30 per square foot, with larger charges possible for complicated commercial work. Check whether the quote includes required runoff protection rather than comparing only the washing rate.
How Long a Crew Needs for a 500-Square-Foot Job
A straightforward 500-square-foot patio may take one worker about 1-2 hours on site, including setup and washing. A 1,000-square-foot driveway often takes 2-4 hours for one worker or a two-person crew, depending on access and dirt. Heavy pretreatment, furniture moving, and detailed edge work add time.
At an effective labor rate of $50-$100 per worker-hour, longer jobs can increase a quote even when the area rate looks low. Scheduling time is not always the same as cleaning time: a contractor may add a minimum charge to cover travel, equipment loading, and setup. Request both the measured area and the expected work included in the price.
Three Concrete Cleaning Quotes Compared by Scope
A 300-square-foot front walk with light soil might receive a $100-$180 quote, or about $0.33-$0.60 per square foot. This reflects a possible minimum charge and roughly 1-2 worker-hours at $60-$80 per hour, plus equipment and travel.
A 600-square-foot driveway with ordinary dirt might cost $150-$330, or $0.25-$0.55 per square foot. A two-person crew could spend about 1-2 hours on site; the estimate should specify whether detergent and edge cleaning are included.
A 1,200-square-foot driveway with widespread oil spots might cost $420-$1,000, or $0.35-$0.83 per square foot. The higher range allows for pretreatment and slower washing; a separate sealing service could add roughly $720-$2,880. These examples show why quotes should list area, stain work, labor scope, and add-ons separately.
Ways to Lower a Driveway Cleaning Quote
Measure the driveway or patio before requesting estimates, and send the same square footage and stain photos to each contractor. Comparing at least three itemized quotes helps reveal whether a low rate excludes degreasing, travel, or wastewater handling. Ask for both the total and the per-square-foot rate so minimum charges are clear.
Move vehicles, planters, and loose items before the crew arrives if the contractor confirms that customer prep is acceptable. Combining nearby concrete areas in one visit may reduce duplicate setup fees. Skip sealing if the concrete does not need it, and avoid paying for stain treatments across the entire surface when marks are isolated.
Keep the requested scope limited to the cleaning the surface needs. Basic washing is usually cheaper than adding multiple coatings or intensive spot work, but a written estimate should state the method, treated area, expected results, and any excluded repairs.
