How to Measure a Driveway for a Pressure Washing Quote (Without Driving Out)

Most driveway quotes are lost before anyone picks up a wand. The customer asks three companies for a price, and the one that answers first with a clear number usually gets the job. Driving out to pace off a slab costs you an hour and puts you behind.

This guide shows how to measure a driveway from satellite imagery in a few minutes, what to include and leave out, how to sanity-check your number against typical driveway sizes, and how to turn the measurement into a price.

Why measurement matters more on driveways than anywhere else

Driveways are the most predictable pressure washing job, so customers compare them on price. That makes your square footage the whole quote.

Fixr publishes driveway pricing of $0.30 to $0.40 per square foot for pressure washing and $0.40 to $0.55 for power washing (heated water) Fixr. At $0.35 a square foot, every 100 square feet you miss is $35. Misread a 900 sq ft slab as 600 and you have given away about $105 of work, or you lose the job to someone who measured.

Driveway size	Published price (labor included)
400 sq ft	$120–$160 Fixr
600 sq ft	$180–$240 Fixr
800 sq ft	$240–$320 Fixr
1,000 sq ft	$300–$400 Fixr
1,200 sq ft	$360–$480 Fixr

The gap between a 600 and a 1,000 sq ft driveway is $120 to $160. Customers cannot tell those two sizes apart by eye, and neither can you from the street.

Step 1: Pull up the address in top-down view

Use any satellite map that lets you trace a shape and read the area: Google Earth, a county GIS viewer, or a measuring tool built on satellite imagery. AboveYard's free Driveway Square Footage Calculator does this in the browser with no download.

Two settings matter:

• Top-down, not tilted. Google's own guidance for Earth is to "measure using a top-down view and the satellite basemap" for best results Google Earth for Developers. A tilted 3D view stretches the slab and adds error.
• Zoom in until the slab edges are sharp. You want to see the line where concrete meets grass, not a blur.

Esri's World Imagery, a common basemap in measuring tools, is published at 0.5-meter resolution across the United States, with sharper imagery in select areas Esri. Half a meter is about 20 inches per pixel, which is plenty to find the edge of a driveway.

Step 2: Check the imagery date

Imagery can be years old. If the customer poured an extension, added a parking pad, or the house is new construction, the satellite view may not show it.

• In ArcGIS-based maps, Esri notes you can click a location to see "the resolution, collection date, and source of the imagery" Esri.
• In Google Earth Pro, the imagery date appears in the status bar at the bottom of the window, and the clock icon opens historical imagery.

If the date is more than a couple of years old, ask the customer one question by text: "Has anything been added or poured since [year]?"

Step 3: Trace the slab, not the lot

Click around the edge of the paved surface and close the shape. For straight driveways, four clicks is enough. For curved or flared driveways, add points along the curve, since every shortcut across a curve cuts off area.

Trace these as separate shapes:

Area	Why it is separate
Main driveway (garage door to sidewalk)	This is what the customer means by "the driveway"
Apron (sidewalk to street)	Often city-owned; some customers want it, some do not
Public sidewalk crossing	Ask before including it
Walkway to the front door	Common add-on, easy upsell
Parking pad or side extension	Frequently missed, often stained
Turnaround or RV pad	Can add hundreds of square feet

Separate shapes become separate lines on the quote. The customer sees exactly what they are paying for, and you can upsell the walkway without re-measuring.

Leave out: the garage floor (unless they ask), gravel shoulders, landscaping beds, and anything you cannot see clearly.

Step 4: Handle trees, shadows, and parked cars

Satellite imagery rarely gives you a clean, empty slab.

Trees. Trace the visible edges, then continue straight edges under the canopy. Driveways are almost always straight-sided, so extending the line is usually right.

Shadows. A shadow from the house can make the edge hard to see. Look for the grass line on the opposite side and use the driveway's width, which is usually constant, to place the hidden edge.

Parked cars. Cars sit on the slab, so trace around them as if they were not there.

If more than a small portion is hidden, stop guessing. Ask for a photo from the street.

Step 5: Sanity-check the number against typical sizes

Before you price, compare your area to published driveway dimensions. If your number is far outside these ranges, re-check your trace.

Driveway type	Typical width	Typical length	Approx. area
One-car	10–12 ft CMI Paving	18–20 ft CMI Paving	180–240 sq ft (width × length)
Two-car	20–24 ft CMI Paving	35–40 ft CMI Paving	700–960 sq ft (width × length)
Average U.S. two-car	16 ft	40 ft	640 sq ft Concrete Network

These are starting points. Concrete Network notes that driveways "may be larger or smaller, depending on the distance from the garage or house to the street" Concrete Network. A long rural driveway can be several times the suburban average.

A one-car driveway traced at 6 or 30 feet wide means something is off.

How accurate is this?

Accurate enough to quote flatwork, not accurate enough to survey a property line.

Google states that Earth measurements "are estimates, may not be 100% accurate, and are not substitutes for onsite or survey-grade measurements," and that area results "don't account for changes in elevation" Google Earth for Developers. For a driveway, elevation barely matters: a sloped driveway has slightly more surface than its flat footprint, so you are measuring a little low, not high.

The bigger risks are human: tracing the wrong edge, missing a side pad, or using old imagery. Steps 2 through 5 cover those.

Step 6: Turn the measurement into a price

Square footage is the base. Then adjust for what the imagery cannot show.

Housecall Pro puts concrete surfaces at $0.20 to $0.40 per square foot and notes that flat, easy driveways "sit at the low end" of that range Housecall Pro. The same guide warns that dirt level "matters more than the total square footage" because oil, rust, and algae take longer and use more product Housecall Pro.

Jobber's worked example shows the full math. A 20 by 40 foot driveway is 800 sq ft; at $0.20 per square foot that is $160 of service cost, plus $8 overhead and $25 materials for $193 total, priced at $276 for a 30% margin Jobber.

A simple remote workflow:

1. Measure each area separately.
2. Multiply by your rate per square foot.
3. Apply your minimum charge if the total is below it.
4. Ask for one photo of the worst stain before adding stain-treatment lines.
5. Send a flat price with each area as its own line.

A worked example

A customer texts an address and asks for a driveway price. You pull it up and trace:

• Main driveway: 22 ft × 38 ft = 836 sq ft
• Apron: 22 ft × 8 ft = 176 sq ft
• Front walkway: 4 ft × 25 ft = 100 sq ft

At $0.30 per square foot:

Line	Area	Price
Driveway	836 sq ft	$250.80
Apron (optional)	176 sq ft	$52.80
Front walkway (optional)	100 sq ft	$30.00
Total, all areas	1,112 sq ft	$333.60

The driveway alone falls between the 800 and 1,000 sq ft rows in Fixr's table above, so the price is in range. The customer sees two optional lines and usually takes at least one.

When you should still go look

Remote measuring covers most residential driveways. Visit, or ask for a video, when:

• The imagery is old and the customer mentions recent work.
• The driveway is mostly hidden under trees.
• It is a large commercial lot or shared private drive.
• The customer describes heavy staining, peeling sealer, or damage.
