Driveway Pressure Washing Cost
Driveways are the highest-volume job in residential pressure washing and the easiest one to underprice. This guide covers 2026 rates for concrete and asphalt, the factors that genuinely change the number, why small driveways cost more per square foot, and three worked examples built with a real pricing model.
What driveway pressure washing costs in 2026
Published benchmark ranges, plus the WashCalc model assumptions used later on this page. Both are labelled so you know which is which.
| Measure | Typical 2026 range | Source |
|---|---|---|
| Concrete driveway cleaning | $0.20–$0.35 / sq ft | HomeGuide, Angi |
| Typical residential job | $100–$300 | HomeGuide, Angi |
| Minimum service charge | $100–$150 | Common trade practice |
| Production rate, surface cleaner | ≈ 450 sq ft / hr | WashCalc default model |
The production rate is WashCalc's default modelling assumption for a 16–20 inch surface cleaner in moderate condition, not a measured industry figure. Time your own first jobs and replace it.
For most homeowners the practical answer is that a standard two-car driveway costs somewhere in the low-to-mid hundreds. A 600 to 900 square foot slab in ordinary condition is the common case, and at published rates that lands between roughly $120 and $300 depending on the market and how dirty it actually is.
Driveways are also the surface where the gap between a cheap quote and a good one is smallest in dollars and largest in result. The difference between $180 and $240 on the same driveway usually comes down to whether the operator is running a proper surface cleaner and pre-treating organic staining, or waving a wand and leaving stripes. That is worth understanding from either side of the quote.
What moves the price
Area sets the baseline. These are what actually move it.
Total area
The starting point, and the only factor most quotes account for. Single-width, two-car and long rural driveways are very different jobs.
Oil and grease staining
Needs degreaser, dwell time and often a second pass. The most common cause of a job running long.
Surface finish
Smooth broom-finish concrete cleans fast. Exposed aggregate, stamped and pebbled finishes hold soil in every recess and slow the pass rate sharply.
Organic growth
Moss, algae and lichen on a shaded or north-facing driveway need chemical treatment, not just pressure. Blasting them off without pre-treatment leaves roots and they return within months.
Material
Asphalt erodes under pressure that concrete ignores, so it wants lower pressure and more chemistry — slower work for a similar result.
Slope and drainage
A steep driveway carries runoff and slurry into the street or a neighbour's property. Managing that is time, and sometimes a reclamation requirement.
Rust deserves its own mention because it is the stain most likely to cause an argument. Rust from irrigation water, fertiliser or a parked trailer does not respond to pressure or to sodium hypochlorite — it needs an oxalic or similar acid treatment, which is a separate product, a separate process and a separate line on the quote. Promising a clean driveway without excluding or separately pricing rust is how a satisfied customer becomes an unhappy one on the day.
The other factor rarely priced is what the driveway drains into. Slurry from a pressure wash carries whatever was on the concrete, and in some jurisdictions and most commercial settings letting that run to a storm drain is not permitted. Residential work usually escapes this; if you are moving toward commercial flatwork, water reclamation is a real cost that has to appear in the rate.
Pricing models and why the minimum exists
Per square foot is how the number is built. The minimum charge is what stops it being wrong on small jobs.
Driveways are the clearest case for square-foot pricing. The surface is flat, the production rate is predictable, and area genuinely correlates with time in a way it does not on a roof or a fence. Multiply area by your rate, adjust for condition, and you have a number that holds up across jobs.
It breaks down at the bottom of the size range, and it breaks down hard. The costs that do not scale with area — driving to the property, unrolling and rerolling hose, setting up and packing down, the invoice and the follow-up — are identical whether the slab is 300 square feet or 1,200. On a large driveway those fixed costs are a small share of the price. On a small one they are most of it.
The productive response to a job under the minimum is not to decline it but to widen it. Walkways, front steps, a patio, a pool surround, the garage apron — all of it is fast work while the rig is already set up and the hose is already run. Adding a second small surface typically costs you under an hour and takes the visit from marginal to genuinely worthwhile.
Hourly pricing has almost no place on driveways. The work is too predictable to justify it, and it penalises the operator with the better surface cleaner — the person who finishes in ninety minutes what a wand would take four hours to do worse.
Worked examples
Three driveways priced with the WashCalc default model, at $35 per crew-hour of labor cost, $20 travel, a 50% target margin and a $150 minimum.
A small, lightly soiled driveway
600 sq ft, light condition, $10 of chemical. The model returns $153 at about $0.26 per square foot, across roughly 1.3 hours of production time. Job cost is near $77, so margin sits right at the 50% target.
Notice how close this lands to the $150 minimum. A slightly smaller driveway, or the same one in a market where you charge $0.20, would fall under it — and the minimum would take over. Jobs in this size band are exactly where adding the front walkway turns a marginal call-out into a reasonable one.
A standard two-car driveway
900 sq ft, moderate condition, $15 of chemical. The model returns $245, about $0.27 per square foot, over roughly 2.5 hours. Job cost is near $123 and the margin holds at 50%.
This is the archetypal residential driveway job and it sits comfortably inside the $100–$300 published range. It is also the job most likely to be underbid: an operator working without a model, quoting from memory of the last driveway, will often land at $180 without noticing that this one is dirtier and 300 square feet larger than that one.
A long driveway with oil staining
1,400 sq ft, heavy condition, $35 of chemical to cover degreaser. The model returns $462, about $0.33 per square foot, across roughly 5 hours. Job cost is near $229 and the margin stays at target.
The heavy condition band is carrying real weight here: it raises the rate by 50% and the hours by 60%, which is the correct asymmetry. Degreasing and second passes cost more time than they earn in rate, which is precisely why heavy-condition work needs to be priced deliberately rather than absorbed. Before sending a number like this, tell the customer plainly that older soaked-in oil lightens rather than disappears. Setting that expectation in the estimate costs nothing; discovering the disagreement on the day costs the job.
DIY versus professional
Concrete is the most DIY-friendly surface there is, so this is a fair fight.
A homeowner with a rented machine and a free Saturday will get a driveway meaningfully cleaner than it was. Concrete tolerates pressure, the consequences of a mistake are cosmetic rather than structural, and there is no height, no chemistry that will kill the garden and no warranty to void. Of all the surfaces covered on this site, this is the one where doing it yourself is genuinely reasonable.
Three things separate that from a professional result. The first is the surface cleaner attachment — a rotating bar under a shroud that covers a consistent width at a consistent distance. It is why a professional finish has no stripes; a handheld wand cleans in arcs and leaves the zebra pattern that becomes obvious as the concrete dries. The second is pre-treatment: organic staining lifts with chemistry, and blasting it off without treating it removes the surface layer of concrete along with the algae. The third is simply flow rate, since a consumer machine at 1.5 gallons per minute will take several times longer than a commercial unit at 4.
The practical calculation is time against money. A rental plus chemicals runs a meaningful fraction of a professional quote for a mid-size driveway, and the job takes most of a day rather than the two to three hours it takes someone with the right gear. For a small, lightly soiled slab that maths can favour DIY. For a large driveway, heavy organic growth, oil staining, or a surface you would rather not risk marking, it stops favouring it quickly.
