Pressure Washing Estimate Calculator
This pressure washing estimate calculator gives you a ballpark cost in seconds. Enter the area in square feet, pick the surface, and the tool multiplies by a per-surface rate, then applies a minimum job floor so the number matches what a real crew would quote. Contractors can flip to Pro mode to set their own rate, minimum, and markup. Nothing is sent anywhere; the math runs in your browser.
Surface type:
The result shows a range of plus or minus 15 percent, because access, dirt level, and local labor move the real quote. Use the midpoint to compare bids, not as a fixed price. For a fuller cost breakdown, see our guide on how much pressure washing costs.
Cost per square foot benchmark for 2026
Pressure washing runs roughly $0.42 to $0.52 per square foot on average, per Homewyse data from January 2026. That figure blends every surface into one number, which is why a flat rate misjudges most jobs. Concrete flatwork prices lower, wood and roof soft-wash price higher, and siding sits in the middle. The table below splits the average apart.
| Surface | Typical rate ($/sq ft) | Why it differs |
|---|---|---|
| Driveway / concrete flatwork | $0.15 – $0.25 | Fast, high-pressure, no chemicals |
| Brick / paver patio | $0.20 – $0.30 | Uneven joints slow the pass |
| Vinyl / aluminum siding (soft-wash) | $0.25 – $0.35 | Detergent dwell time, ladder work |
| Wood deck or fence | $0.40 – $0.50 | Low pressure, careful passes, brightener |
| Roof soft-wash | $0.42 – $0.52 | Height risk, chemical mix, slow rinse |
Typical total price ranges for common jobs
Most residential pressure washing jobs land between $175 and $600 total. You can expect to pay between $250 and $450 for an average driveway, and $300 to $600 to soft-wash a two-story house. The ranges below assume typical dirt levels and normal access. Steep roofs, heavy mildew, or second-story reach push the number toward the high end.
| Job | Typical area | Expected total |
|---|---|---|
| Two-car driveway | 600 – 1,000 sq ft | $175 – $300 |
| Single-story house (siding) | 1,200 – 1,600 sq ft | $250 – $450 |
| Two-story house (siding) | 2,000 – 2,600 sq ft | $350 – $600 |
| Wood deck (400 sq ft) | 400 sq ft | $175 – $250 |
| Roof soft-wash (1,800 sq ft) | 1,800 sq ft | $450 – $900 |

The inputs that drive your estimate
Four variables set nearly every pressure washing estimate: area size, surface type, minimum job fee, and any soft-wash or travel surcharge. Area and surface do the heavy lifting. The minimum fee protects the crew on small jobs, and surcharges cover chemicals or distance. Understanding these lets you sanity-check any quote you receive.
- Square footage / area size. The single biggest driver. Measure length times width for flatwork, or use wall height times perimeter for siding.
- Surface type. Concrete, siding, wood, and roof each carry a different rate because pressure, chemicals, and risk differ.
- Minimum job fee. Most crews will not roll a truck for under $150 to $250, regardless of size.
- Surcharges. Soft-wash chemical, roof height, gutter brightening, or travel beyond a service radius.
The actual formula (worked example)
The math behind any pressure washing estimate calculator is simple: area times surface rate, compared against a minimum, plus surcharges. Competitors rarely show it, so the number feels arbitrary. Here is the full formula and a worked driveway plus siding job so you can reproduce and trust the total.
Estimate = (Area × Surface rate) or Minimum fee, whichever is greater, + surcharges.
Worked example, a 900 sq ft concrete driveway plus 1,500 sq ft of vinyl siding:
- Driveway: 900 × $0.20 = $180
- Siding (soft-wash): 1,500 × $0.30 = $450
- Subtotal: $630, above the $200 minimum, so no floor applied
- Soft-wash chemical surcharge on siding: +$40
- Estimate: $670 (compare quotes within roughly $570 to $770)
If that same customer only wanted the 400 sq ft back patio (400 × $0.25 = $100), the $200 minimum fee kicks in and the price becomes $200, not $100. That floor is why small jobs feel expensive per square foot.
Contractor pricing mode: rate, minimum, and markup
New and small pressure washing contractors need a quoting tool, not just a homeowner ballpark. In Pro mode above, set your own per-sq-ft rate, your minimum job fee, and a markup percentage for overhead and profit. Southeast Softwash and similar operators frame quotes as “you pay between” a low and high figure, which the calculator produces automatically. Build your rate from cost, not a competitor’s number.
A defensible rate covers labor, fuel, chemicals, equipment wear, and margin. If your loaded labor cost is $65 per hour and your crew cleans about 300 sq ft per hour on siding, your floor rate is around $0.22 per square foot before profit. Add margin on top. Our primer on starting a pressure washing business walks through overhead and pricing structure in detail.
Labor vs. project cost, and regional variation
Labor is 40 to 60 percent of a residential pressure washing project cost. The rest covers chemicals, fuel, equipment depreciation, insurance, and profit. Region matters too: metro Northeast and West Coast markets often run 20 to 30 percent above rural Southeast and Midwest rates, tracking local wage and insurance costs. Adjust any national benchmark toward your own market before comparing quotes.
| Cost component | Share of a typical residential job |
|---|---|
| Labor | 40% – 60% |
| Chemicals / soft-wash mix | 5% – 15% |
| Fuel, equipment, insurance | 15% – 25% |
| Overhead + profit | 15% – 25% |
Soft-washing, which uses low pressure and a sodium hypochlorite mix for siding and roofs, often costs slightly more than straight high-pressure work because of chemical cost and slower application. See our overview of pressure washing chemicals for what those mixes contain.
How to use the estimate to compare quotes
Treat the calculator’s midpoint as a reference line. Get three written quotes, then check each against the estimate. A bid more than 15 percent below the range may skip insurance, chemicals, or surface protection. A bid well above it should itemize why (roof height, heavy staining, sealing). Ask every contractor to break out area, rate, minimum, and any surcharge so you are comparing the same math.
- Run the calculator for each surface separately, then add them.
- Collect three itemized written quotes.
- Flag any bid outside the plus or minus 15 percent range and ask why.
- Confirm insurance and whether surface protection or sealing is included.
Frequently Asked Questions
How much does it cost to pressure wash a house?
Pressure washing a house typically costs $250 to $600, depending on size and stories. A single-story home with 1,200 to 1,600 sq ft of siding usually runs $250 to $450, while a two-story home at 2,000 to 2,600 sq ft runs $350 to $600. Siding is normally soft-washed at about $0.25 to $0.35 per square foot, with a minimum job fee of $150 to $250.
How much do pressure washers charge per square foot?
Pressure washing averages $0.42 to $0.52 per square foot (Homewyse, January 2026), but the rate varies by surface. Concrete driveways run $0.15 to $0.25, siding soft-wash $0.25 to $0.35, wood decks $0.40 to $0.50, and roof soft-wash $0.42 to $0.52. Always price by surface rather than applying one blended rate to the whole job.
How do you estimate a pressure washing job?
Estimate a pressure washing job with this formula: area in square feet times a per-surface rate, compared against your minimum job fee, plus any surcharges. Measure each surface, apply its own rate ($0.20 concrete, $0.30 siding, $0.45 wood), take the greater of that subtotal or your minimum, then add soft-wash chemical or travel charges. A 900 sq ft driveway at $0.20 estimates near $180.
What is the minimum charge for pressure washing?
Most pressure washing companies set a minimum job fee of $150 to $250. This floor covers the cost of loading equipment, travel, setup, and cleanup on small jobs that would not otherwise justify a truck roll. It is why a tiny 300 sq ft patio can cost the same $200 as a job twice its size. Always ask a contractor for their minimum before booking.
How much should I charge to pressure wash a driveway?
Charge $0.15 to $0.25 per square foot for a concrete driveway, subject to your minimum job fee. A typical 600 to 1,000 sq ft two-car driveway estimates at $175 to $300 total. Add for oil-stain treatment, rust removal, or post-cleaning sealing. If the area math falls below your $150 to $250 minimum, bill the minimum instead of the per-square-foot figure.
Is there a free pressure washing estimate calculator or app?
Yes. The free pressure washing estimate calculator at the top of this page runs entirely in your browser, with no signup or data collection. It offers a homeowner ballpark mode and a contractor Pro mode where you set your own rate, minimum, and markup. Standalone quoting apps like Jobber or Housecall Pro add scheduling and invoicing, but cost a monthly subscription.
How do you price a commercial pressure washing job?
Commercial pressure washing is often priced per square foot at lower rates than residential ($0.05 to $0.15 for large flat lots) because volume and repeatable access cut per-unit cost. Storefronts, fleets, and dumpster pads may price per unit or hourly instead. Factor after-hours scheduling, water access, wastewater capture rules, and a general liability policy sized to the client’s requirements when quoting commercial work.
Does soft washing cost more than pressure washing?
Soft washing often costs slightly more than high-pressure washing per square foot because of chemical cost and slower application. Soft-wash uses a low-pressure sodium hypochlorite mix to clean siding and roofs safely, which adds a chemical surcharge many crews bill at $30 to $60 per job. High-pressure work on concrete needs no detergent, so it is usually cheaper for equivalent square footage.
