Pressure Washing Estimate Template: Surface by Surface

Short answer: A pressure washing estimate template prices every surface on its own line in its own unit — flatwork and siding by the square foot, fences and gutter faces by the linear foot, small jobs at a stated minimum. The method belongs on the line too, because concrete takes high pressure and vinyl siding and shingles take a soft wash. Add water access, wash-water handling, and a 30-day expiration.

One number for a whole property is how this trade generates damage claims. “Wash the house and driveway, $400” gives the customer no idea that the concrete is getting 3,500 psi and the siding is getting chemistry at garden-hose pressure, and it gives you nothing to point at when they ask why the fence was not included. Split the page by surface. For building your own rates from production time and chemical cost, see how much to charge for pressure washing; the approved estimate then becomes the pressure washing invoice with the same line numbers.

What lines does a pressure washing estimate need?

One line per surface, plus four lines that are not surfaces at all and get forgotten anyway.

Line	Unit	Why it stands alone
Each flat surface — drive, walks, patio, pool deck	Sq ft	Different areas, sometimes different soiling, always a separate measurement
Siding	Sq ft of wall	Different method entirely, and the customer may want it and not the concrete
Roof	Sq ft of roof, or per building	Chemical work with its own risk profile and its own release language
Fence, gutter faces, rails, curbing	Linear ft	Time scales with length, not area, and sides multiply it
Stain treatment — oil, rust, artillery fungus, gum	Per stain or per spot	Extra product, extra dwell, extra pass, and no promise of full removal
Water supply	Flat, if you are bringing it	A buffer tank and a fill trip are real hours
Wash-water handling	Flat or per job	Containment, mats, or vacuum recovery on jobs that need it
Access	Flat	Second story, roofline reach, locked gates, elevator on commercial
Minimum charge	Flat floor	Applies when the measured lines land under it

Above those: business name, insurance carrier and policy number if you carry it, the property address, the estimate number, the date, and the expiration date. Below them: total, when you are paid, and how the customer says yes.

Which surfaces get high pressure, and which get soft wash?

This is the section that keeps you out of a claim, and it belongs on the customer’s page in plain language, not just in your head.

Surface	Method	What high pressure does to it
Broom-finish concrete, sidewalk, curb	Surface cleaner at full pressure	Nothing, if you keep the bar moving
Stamped or colored concrete	Reduced pressure, test panel first	Strips sealer and lifts color
Pavers	Moderate, then re-sand joints	Blows out the joint sand — the re-sand is a separate line
Brick, mortar, older stone	Low pressure, chemistry, hand work	Eats mortar joints, and repointing is not your line of work
Vinyl siding	Soft wash	The Vinyl Siding Institute points operators to a soft wash system rather than high-pressure equipment; most manufacturers put the cleaning limit far below what a rental machine puts out, and high-pressure cleaning voids common siding warranties
Painted wood siding	Soft wash, test spot on chalky or failing paint	Peels paint and drives water into the sheathing
Stucco and EIFS	Soft wash only	Cracks the finish coat and forces water behind it
Asphalt shingle roof	Chemical only, low-pressure rinse	The asphalt shingle manufacturers’ association is explicit that high-pressure washing is likely to damage asphalt roofing and should not be used to remove algae — see ARMA on algae discoloration
Wood deck and fence	Low pressure, cleaner then brightener	Furs the grain and leaves wand stripes you cannot sand out

Write the method into the line description. “House exterior — soft wash application, low-pressure rinse, no high-pressure contact with siding” costs you eight words and it is the sentence you want in writing when a panel that was already cracked shows up in a photo two weeks later.

How do I measure each surface for the estimate?

With a wheel and a tape, on the property. Satellite imagery gets you a callback list, not a price.

Surface	The measurement
Driveway	Length × width, and measure the apron separately if it is a different pour
Walks and stoop	Length × width each, added as one line but measured separately
Patio or pool deck	Length × width, minus anything permanently fixed on it
Siding	Perimeter × average wall height, plus gable triangles at base × height ÷ 2
Roof	Ground footprint, then a pitch multiplier — and note the pitch on the line
Fence	Linear feet, and state one side or both, because both sides is two jobs
Gutter faces	Linear feet of run, counted separately from the roof

A 60 by 30 ft ranch works out at 180 ft of perimeter. At 9 ft of average wall height that is 1,620 sq ft, plus two gable ends at 30 × 6 ÷ 2 each for another 180, so 1,800 sq ft of wall. Put that arithmetic on the estimate. Customers who see the measurement stop treating your number as a guess.

Why does the estimate need a minimum charge line?

Because most of what you are paid for happens before the trigger gets pulled. Unspooling hose to a back gate, priming, mixing the tank, wetting and tarping the plantings, then reeling all of it back onto the trailer runs the better part of an hour whether the job is 300 square feet or 3,000. Add the drive on both ends and a small job has spent your morning.

Small job, measured honestly
Surface actually cleaned	340 sq ft of front walk
Time on the machine	25 min
Setup, plant protection, teardown	40 min
Round-trip drive	35 min
Total off the shop clock	1 hr 40 min for 25 minutes of production

Six percent of that job was cleaning. Pricing it per square foot at any rate you would use on a 1,200 sq ft driveway loses money in a way no volume can fix. Set a floor, print it on the estimate as its own line — “minimum service charge applies” — and quote small jobs at the floor rather than apologizing your way down to a per-foot number.

What does a filled-in pressure washing estimate look like?

A ranch house with vinyl siding, a driveway, and a walk. Every rate below is a placeholder from one market. Substitute your own: pressure washing prices move with local competition, water cost, disposal rules, and season more than almost any other exterior trade, and the same house can price 50 percent apart across a metro area. Copy the structure, not the numbers.

Included: pre-treatment where the surface calls for it, plant protection, rinse of adjacent surfaces splashed during the work. Not included: roof, fence, rear patio, window cleaning, screen removal, gutter interiors, re-sanding paver joints.

What does that bundle credit actually cost me?

Sixty-seven dollars, in the only currency that matters. Markup and margin are not the same number, and a discount comes out of the second one.

Markup is what you add to your cost. Margin is what survives in the price. Add 30 percent to a $600 cost and you get $780, where your $180 is 23 percent of the price, not 30. To actually keep 30 percent you divide: $600 ÷ 0.70 = $857.

Now the discount. Say this ticket cost you $540 in labor, overhead, chemical, and fuel, and you priced it at $842 for a 36 percent margin.

What you do	Price	Margin left
Price at 36% margin	$842	36%
Give an 8% bundle credit	$775	30%
Give a 15% credit	$716	25%
Give a 25% credit	$632	15%

An 8 percent discount ate a sixth of your profit on the job. That can be a good trade when it puts four surfaces on one setup instead of two visits, since the setup was the expensive part. It is a terrible trade when you hand it out to close a single-surface job. Decide which one you are doing before the number leaves your mouth.

Where does the wash water come from, and where does it go?

Two questions, both of which belong on the estimate rather than in a surprise.

Water in: check the spigot before you price. Fill a five-gallon bucket and time it. A hose that fills it in under a minute keeps up with a 4 gpm machine; one that takes two minutes does not, and you are bringing a buffer tank, which is trailer weight, a fill stop, and a line on the estimate.

Water out: rinse water from commercial washing is treated as process wastewater, not rain. Section 301 of the Clean Water Act prohibits a point-source discharge to waters of the United States without an NPDES permit, and municipal stormwater programs generally prohibit wash water from pressure washing and similar activities from entering the storm sewer system — the EPA’s NPDES stormwater program is the framework local ordinances hang off. In practice, what your city requires runs from nothing on a residential driveway to full recovery and hauling on a restaurant pad or a fuel island.

Job	What the estimate should say
Residential driveway, no detergent to a drain	Standard rinse, no containment required
Restaurant or drive-through pad, grease present	Berm and mat containment, water recovered and disposed per local rules — priced as its own line
Fuel island or shop apron	Recovery plus disposal manifest, and the property is usually the regulated party, so name that in writing
Fleet or lot washing	Confirm the site’s own discharge permit before you quote

Do not swallow containment inside a square-foot rate. It is gear, hours, and disposal, and it is the fastest way to turn a commercial job you were proud to land into a loss.

Which items belong on the estimate as conditional?

Anything the wash will reveal rather than fix. Give it a price, keep it out of the total, and have the conversation before you spray.

Condition	How to write it
Oxidized or chalky vinyl and aluminum	Test spot first. A soft wash removes growth, not oxidation; restoring chalked siding is a separate product and a separate price. Say so before, not after
Artillery fungus on siding	Those black specks are embedded. Improvement only, no removal guarantee, priced by the hour if the customer wants an attempt
Rust from irrigation or fertilizer	Oxalic-based treatment, separate application, results depend on how long it has sat
Failing paint on wood	Test area. Loose paint comes off in a wash; that is the coating failing, not the wash, and it needs to be in writing
Roof over 15 years, or brittle shingles	Walkthrough with photos before pricing. Some roofs get declined, and declining one is cheaper than replacing it
Screens, storm windows, window film	Removal, cleaning, and reinstall are separate lines, and spotting on glass after a house wash is normal unless a glass line is on the estimate
Previously sealed concrete	The seal may come off in patches. Test panel first, re-seal quoted separately
Locked gate, dog, or no access on the day	Trip charge stated on the estimate, not invented afterward

Photograph existing damage during the walkthrough, on the same day the estimate goes out. Cracked panels, chipped stucco corners, a hairline in the stamped patio — those photos are the estimate’s attachment, and they end more disputes than any paragraph you can write.

How long is the estimate valid, and how does the customer approve it?

Thirty days, printed next to the estimate number. Chlorine pricing moves, your calendar fills through the season, and an estimate someone found in April should not bind an August Saturday. For commercial and recurring work, quote the visit price and the frequency separately so an annual schedule can be repriced without renegotiating the whole thing.

Approval takes three things: the total, the payment expectation, and a reply you can keep. Residential exterior cleaning normally does not need a deposit — the job takes one visit and you are on site when it finishes — so the more useful sentence is when you get paid, and “due on completion” beats “net 30” on a driveway you will never see again. Ask for a text reply approving the estimate and confirming the water source and gate access. That single message resolves most of what goes wrong on the morning of the job, and the collection habits in how to get clients to pay start there rather than at the first unanswered call.

What do I keep once the trailer is hooked back up?

Before-and-after photos of each surface you billed, the walkthrough photos of pre-existing damage, and the receipts for chemical, fuel, and any disposal.

Keel is an iOS app that runs entirely on your phone: no account, no bank connection, no cloud, no login, and an App Store privacy label that reads Data Not Collected. It does not write the estimate — that stays wherever you build it now — but the moment the last surface is rinsed you can turn the approved lines into an invoice from the driveway in under a minute, with your logo, your numbering, your brand color, and a payment link that renders as a QR code the homeowner scans before you have coiled the hose. That is how a $775 residential ticket gets paid the same day instead of joining a follow-up list. The chlorine and surfactant run gets photographed at the counter and read on device by Apple Intelligence, so a season of drum purchases is filed rather than fading in a truck cupholder — chemical, fuel, and gear are all ordinary self-employed tax deductions if you can produce the record. Drives between properties get logged as trips. Free covers unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 Lifetime purchase, not a subscription. You can get it on the App Store.

Frequently asked questions

What should a pressure washing estimate include?

Each surface on its own line with its own unit and the method named, the measured quantity, stain treatments as separate spots, water source, wash-water handling if the site requires it, access notes, a minimum service charge, exclusions, an expiration date, and how payment is taken. Photos of pre-existing damage should be attached the same day the estimate goes out.

Should I price pressure washing per square foot or per job?

Measure per square foot, then present the way the customer buys. Flatwork and siding measure cleanly in square feet; fences, gutter faces, and rails measure in linear feet. Present the total per surface so the customer can drop the fence and keep the driveway. Small jobs fall back to a stated minimum charge, because setup and travel dominate them.

Why does vinyl siding need a soft wash instead of high pressure?

High pressure cracks panels, chips edges, and drives water behind the siding through seams, where it stays. The Vinyl Siding Institute points to a soft wash system rather than high-pressure equipment, and high-pressure cleaning voids common siding warranties. A soft wash applies cleaner at low pressure, lets it dwell, and rinses — the chemistry does the work, not the machine.

Can I pressure wash an asphalt shingle roof?

No. The asphalt roofing manufacturers’ association states that high-pressure washing is likely to damage asphalt roofing and should not be used to remove algae, because pressure strips granules faster than it removes growth. Roof cleaning is a low-pressure chemical application with dwell time and a gentle rinse, and it needs its own estimate line and its own release language.

How much should the minimum charge be on a pressure washing estimate?

Build it from your own numbers: round-trip travel, setup, plant protection, and teardown, times your hourly cost, plus a chemical allowance, then divided by one minus your target margin. Most operators land somewhere in the $150 to $250 band, but a dense suburb and a 40-minute rural drive produce very different floors. Print it on the estimate.

Do I need a deposit for pressure washing?

Usually not on residential work, since the job is one visit and you are standing there when it ends. Bill due on completion and take payment on site. Deposits make sense on commercial jobs that require containment gear, a night crew, or scheduled recurring visits, and on any job where you buy material specifically for that property. State the terms on the estimate either way.
