Pressure Washing Driveway Cost Calculator

The pressure washing driveway cost calculator prices concrete flatwork: driveways, sidewalks and patios. Enter the area in square feet and your base rate per square foot, pick the surface, count the oil stains to pre-treat and choose whether to add a soft-wash treatment for algae or mildew. The tool shows the total, the effective price per square foot and a rough estimate of the water used.

It is meant for the washer who quotes by the square foot, and for the homeowner who wants to check a quote. The default rates are starting points, not market prices, so replace them with what you charge, and compare the result with the published national ranges further down the page. It runs in your browser, is free and needs no account. Nothing you type is uploaded.

How to use the pressure washing estimator

1. Enter the flatwork area in square feet. Measure length times width for each strip of concrete and add them together.
2. Choose the surface: broom-finish concrete, exposed aggregate or brick and pavers. Each has its own factor, because joints and texture take longer to clean. Plain concrete has a factor of 1.0, so your base rate applies unchanged.
3. Enter your base rate per square foot for plain concrete. The default is $0.22.
4. Enter the number of oil stains to pre-treat and your price per stain.
5. Tick the soft-wash box if you also treat the surface for algae or mildew, and check the price of that line.
6. Read the total, then the effective rate per square foot, which includes the stains and the soft wash lines you ticked.
7. Compare the total with the Thumbtack average for the same surface in the table below, and check the effective rate per square foot on its own, and raise your base rate or add a minimum charge if your total comes out low.
8. Print the quote or save it as a PDF from the print window to hand to the customer.

Use Copy estimate to paste the quote into a message, or Print to hand the customer a clean one-page quote to keep. Every rate on the page is a starting value that you can change, so adjust the surface factor and the stain price until the total matches what you really charge for the job.

How much does it cost to pressure wash a driveway?

Published national averages give a check on your own rate. Thumbtack’s power washing prices page (updated 2026-01-05, read 2026-10-20) lists these per-job averages by surface, which you can set beside the estimate:

These are whole-job averages for each surface, not prices per square foot, and they do not depend on the size of your job, so use them only as a sanity check on the surface factor. The default estimate here, 2,500 sq ft of concrete at $0.22 a square foot with three stains and a soft wash, comes to $649; without the stain treatments and soft wash the washing line alone is $550. Those rates are our own starting points, not published prices: set them to what you charge.

How to quote pressure washing concrete driveways

The quote adds:

• Washing = area × base rate × surface factor (concrete ×1.0, exposed aggregate ×1.2, brick or pavers ×1.35)
• Oil stains = count × $18
• Soft wash = $45 when ticked

With the defaults (2,500 sq ft at $0.22, 3 stains, soft wash) that is $550 + $54 + $45 = $649, about $0.26 per sq ft. Pavers take longer because joints need care and often re-sanding.

How much water does pressure washing a driveway use

A 4 gallons-per-minute machine with a surface cleaner covering about 1,000 sq ft an hour uses roughly 0.24 gallons per square foot, so 2,500 sq ft takes about 600 gallons. Your machine’s flow rate and pace change this, so treat it as a rough figure.

How do I price a pressure washing job so I make money?

Start from the time, not the area. A surface cleaner covering about 1,000 sq ft an hour means a 2,500 sq ft driveway is two and a half hours on site, before set-up, driving and clean-up. Divide your price by those hours and compare the result with what you need to earn per hour. If the answer is low, raise the base rate or the minimum charge.

Flatwork that is badly stained, very large or hard to reach takes longer than the area suggests, so quote it separately. Say in writing what you will not promise, such as removing old oil that has soaked into the concrete.

Frequently asked questions

Are the default rates market prices?

They are starting points. Check what washers charge in your area and enter your own base rate.

Does the soft wash replace pressure washing?

No. On flatwork it is a chemical pre-treatment for organic growth; the washing line still applies.

Do I need a minimum charge?

Most washers have one, because travel and set-up are the same for a small patio and a long driveway. Add it when the total comes out low.

Can oil stains always be removed?

Not always. Old stains soaked deep into concrete often fade but do not disappear; say so in the quote.

Does the estimate include the water?

No. The water figure is only information, about 0.24 gallons per square foot. Most customers supply the water, so it is not a charge in the estimate.

Can I print the estimate for a customer?

Yes. Use the print button under the result to print the quote or save it as a PDF. It prints the numbers and the lines you ticked, so check the base rate before you hand it over.

Should I charge more for pavers than for concrete?

Usually yes. Pavers have joints that need careful cleaning and often re-sanding, so the estimator multiplies the base rate by 1.35 for brick and pavers, and by 1.2 for exposed aggregate.
