Pressure Washing Price Calculator
Work out what to charge for a driveway, siding, deck, roof or fence wash. Real rates, condition multipliers and the effective hourly rate.
Pick the surface, put in the measurement, say how dirty it is. You get a suggested price, the line-by-line maths behind it and the hourly rate it works out at once you are standing in the driveway. It runs in your browser. No sign-up, no email, nothing sent anywhere.
The rates below are the defaults Servetic loads into a new pressure washing account. They are a starting point, not a quote - local rates, travel and water access move every one of them.
Flat rate. Concrete flatwork is priced per job because a surface cleaner covers ground fast and measuring costs more time than it saves.
Square feet. A two-car driveway is usually 600-800. On a flat-rate service the size does not change the price - it only feeds the time estimate.
Ordinary dirt and a bit of green. This is the price as listed.
Used only to sanity-check the result. It never changes the price.
Sensible range $100 - $140: Plus or minus 15%, which is roughly the gap between a job that goes to plan and one that needs a second pass.
How it got there
Flat $120 per job, whatever the tape says.
At $120 over 1.5 hr you are clearing about $80 an hour on site, under the $85 you asked for. Either the job needs a higher price, or it needs to be a shorter visit - and before overheads and drive time it is thinner still.
This is a starting point, not a quote. It does not know your drive time, whether there is a working outside tap, or what the shop down the road charges.
The setup and the risk, not the washing.
Measured end to end. Both sides doubles it.
Why three different pricing methods sit on one truck
If you have ever tried to price a fence the way you price a driveway you already know the answer. Here is the reasoning behind each method, and where each one falls over.
Flatwork is priced per job, not per square foot
A surface cleaner on concrete covers ground faster than almost anything else you own. A two-car driveway is twenty minutes of actual washing once the machine is running, and the difference between a 600 square foot driveway and an 800 square foot one is about four minutes. Measuring it, writing the measurement down and multiplying it out costs you more time than those four minutes are worth, which is why driveways and patios are sold as a flat price and why the default here is a flat $120.
The flat price does have a ceiling. Somewhere past half again the usual size - a long shared driveway, a courtyard, a commercial forecourt - the flat rate stops covering the day and you go back to measuring. The calculator flags it when the number you type is well above what a flat rate assumes. If you want to know what your flat price works out at per square foot, divide: $120 over 700 square feet is about $0.17, which is a useful sanity check next to the $0.50 you charge on siding.
Houses are priced by area and then by storey, because access is the real cost
House siding is sold per square foot of elevation - wall runs multiplied by height, not the floor area of the house. At $0.50 a square foot a 1,800 square foot elevation prices itself at $900 without anybody driving out to look at it. That works because a soft wash is chemical-led: the mix does the cleaning, so the time you spend is roughly proportional to how much wall there is.
Then the second storey multiplier lands on top, and it is worth understanding why it is 50% rather than something smaller. Nothing about the upper elevation is harder for the pump. What changes is you. Ladders come off the truck, get set, get moved every few feet and get packed away. An extension wand is heavier and slower and less accurate, so you work carefully and you work with one eye on the gutter. On a two-storey house the upper half routinely takes as long as the whole ground floor did. That is the cost driver: access and setup, not surface area, which is exactly why the multiplier applies to the line rather than to a separate upstairs measurement.
Difficult access is the same idea in a different shape, and at 35% it is the one most people forget to charge for. A hose run past a locked gate, a tap two hundred feet from the work, a steep bank you cannot get the machine onto, a courtyard reached through the house. None of that shows up in a measurement. All of it shows up in your afternoon.
Fencing is the one thing measured end to end
A fence is sold per linear foot - $3.50 here - because the height is more or less constant and the length is the only thing that varies. Walk it with a wheel, write down the run, multiply. The trap is sides: if the customer wants both faces cleaned, that is double the run, not the same number with a bit added. The second trap is what the fence is made of. Old timber soaks up chemical and time in a way vinyl does not, and if it is soft enough to furr under pressure you are into a slower, gentler pass. Neither of those is in the linear foot rate, so both belong in the condition multiplier or in a conversation before you commit.
Soil condition, the minimum, and the number this page cannot see
Heavy soil at 25% covers the second pass. Black algae streaks on a north-facing wall, four years of moss on a deck, oil under where the car parks - none of those come off in one go, and pretending they do is how a two-hour job becomes a four-hour job at the two-hour price. Notice too that there is no discount tier for a clean surface. A lightly soiled driveway still needs the truck, the setup and the pack-down, and those do not get cheaper because the concrete is tidy.
The $75 minimum exists for the same reason and is applied last, after every multiplier. Below it you are paying for the privilege of working. If a job keeps landing on the minimum, the fix is almost never a higher minimum - it is bundling that little walkway onto a visit you were making anyway.
Everything above still leaves out the three things that decide whether a price is right: what your local market will pay, how far you are driving, and whether there is water on site. A forty-minute drive each way is most of a job's margin. No calculator on the internet knows that about your week, so treat the output here as the number you start from and adjust with what you know.
Where these numbers come from
Every price and multiplier on this page is the default in Servetic's pressure washing template - the service list a new account is set up with. They are not survey data and they are not an average of the market.
The production rates behind the time estimate are the calculator's own assumption and are stated as such. Nothing on this page is based on usage statistics, because we are not going to invent any.
A starting point, not a quote. Anything you would want to see before committing - surface material, tree cover, parking, water pressure - is still worth a look in person or a photo from the customer.
What operators ask about pricing a wash
Including the ones where the answer is no.
It depends on which surface you are cleaning and how you bill it. The defaults this calculator uses are a flat $120 for a driveway, a flat $80 for a deck or patio, $0.50 per square foot for house siding, $0.75 per square foot for a roof and $3.50 per linear foot for a fence, with a $75 minimum on any job. Heavy soil adds 25%, second-storey work adds 50% and difficult access adds 35%. Those are the starting numbers in Servetic's pressure washing template, and they are a starting point rather than a quote - your local market, your travel and whether there is water on site all move them.
For soft-washed house siding, $0.50 per square foot is the default here, and roofs sit higher at $0.75 because of the setup, the chemical and the risk. Flatwork like driveways and patios is usually not sold per square foot at all - it is sold as a flat price, because measuring a driveway takes longer than washing 200 square feet of it. If you do want a per-square-foot figure for flatwork, take your flat price and divide it by the area you actually cleaned: a $120 driveway at 700 square feet works out at about $0.17 per square foot.
Because the cost driver on a house wash is access and setup, not square footage. Ground-floor siding is a wand and a walk. The upper elevation means ladders, an extension wand, moving the ladder every few feet and working slower because you are being careful. The pump does not care how high the wall is; your day does. That is why the multiplier is on the whole line rather than on a separate upstairs measurement.
No. It gives you a starting number and shows the maths behind it, so you can see which multiplier did what. A quote needs things this page cannot know: how far you are driving, whether there is a working outside tap, what the surface is actually made of, whether the neighbour's car is parked on the run, and what other operators in your town charge. Treat the output as the number you begin negotiating from, not the number you put on paper.
The template carries a $75 minimum price, and it is applied after the multipliers. A 20-foot strip of walkway or a small gate section can price out below what it costs to load the truck, drive there, unload the reel and pack up again. The minimum is the floor that stops those jobs being sold at a loss. If a job keeps landing on the minimum, the honest answer is usually to bundle it with something else on the same visit.
Put in what you want to clear per hour on site, before overheads. The calculator estimates time from a production rate and a half hour of setup, scales that time by the same multipliers it applied to the price, and tells you the effective hourly rate the suggested price works out at. If that number lands under your target, the job is priced too low for the time it will take - which is worth knowing before you send it, not after. The production rates are this calculator's own assumption, not a product setting.
