Price a house wash, driveway, patio, deck, fence, or roof by the square foot. Add a surcharge for heavy algae, mold, or oil stains, take a repeat-service discount off the surfaces, add gutters and windows, apply your minimum charge, and see how many crew-hours the price pays for. Then print a one-page quote. No signup, and nothing you type leaves your browser.

Sample prices The prices below are made up so you can see how it works. Type in your own prices.

1. Your business and the client

2. Your prices

Price each surface per square foot (fences per linear foot). Rename a surface or use the blank row for your own.

Condition surcharges

Added to one surface line when that surface is in heavy shape. 25% means that surface costs 1.25 times your normal rate. Normal adds nothing.

Repeat-service discount

Comes off the surfaces only, not the add-ons. Jobs per year is used for the "about per year" line. Set a discount to 0 if you don't offer one.

Add-ons

Minimum, rounding, and your hourly target

3. This job

Pick each surface, type its size (square feet, or linear feet for a fence), and pick a condition if it's heavy.

Add-ons for this job

Leave Qty blank for 1.

4. The price

5. Notes for the quote

How to price pressure washing

1. Know your hourly number. Add up what a crew-hour costs you to run (labor, truck, rig, chemicals, insurance, and the time you spend on quotes and driving) plus your margin. The free pricing calculator works it out.
2. Time your surfaces. Note how many square feet an hour your crew cleans on each surface: driveway with a surface cleaner, soft wash on one-story and two-story siding, decks, roofs. Your own job notes are the best source.
3. Turn it into a rate. Rate per square foot = your hourly number ÷ square feet per hour. With made-up numbers: if a crew-hour has to bring in $75 and your crew cleans about 400 square feet of concrete an hour, that's $75 ÷ 400 = about $0.19 per square foot.
4. Price what changes the work. A surcharge for heavy algae, mold, or oil stains on that surface, add-ons priced on their own, and a minimum charge so small jobs still pay for the trip.
5. Check the crew-hours. Step 4 shows how many crew-hours the price pays for at your target rate. If the job will take longer than that, the price is too low for that job.

Prices for pressure washing vary a lot by city, season, and job. Set your rates from your own costs and times, and change them in step 2.

How the math works

• Surface amount = size × your rate for that surface, to the cent.
• Condition extra = that surface amount × the condition percent. Each surface line gets its own.
• Repeat-service discount = surfaces total × the discount for how often. It comes off the surfaces only, not the add-ons.
• Add-ons = quantity × price. A blank quantity counts as 1.
• Job price = surfaces − discount + add-ons, raised to your minimum charge if it's lower, then rounded to the nearest dollar amount you picked.
• Total = job price + sales tax (job price × your tax rate).
• Crew-hours = job price ÷ your target hourly rate, to the nearest quarter hour. Hours on site = crew-hours ÷ crew size.

The made-up sample: surfaces $906.00 + $104.40 in condition extras = $1,010.40, minus the 5% once-a-year discount ($50.52), plus $230.00 in add-ons = $1,189.88, rounded to $1,190.00. At $75 an hour that pays for 15.75 crew-hours, about 8 hours on site for a crew of 2.

What a pressure washing quote should include

A clear quote answers the client's questions before they ask, and gives you something to point to if a stain doesn't come out or the weather moves the date. Put these on every quote:

• Who and where. Your business, phone, and email, the client's name, and the property address.
• Each surface and its size. House siding, driveway, patio, walks, deck, fence, roof: one line each, with the square feet (or linear feet for a fence), so the client sees what's covered and you can check it at the next wash.
• The rate and any condition extra. Heavy algae, mold, or oil stains as their own amount on that surface's line, so the client sees why one surface costs more.
• Add-ons priced on their own. Gutters, windows, screens, rust spots, sealing, and the rest, each with its own price and billed only when it's done.
• How often and any repeat discount. One-time or a repeat schedule (once a year, twice a year, every 3 months), and what the discount covers.
• The job price, tax, and total. The minimum charge if it applies, sales tax if you charge it, and the total the client pays.
• What you need from the client. A working outside water spigot, windows and doors closed, cars off the driveway, pets inside, and anything fragile moved.
• Stains and existing damage. Which stains may fade but not come out all the way, and that you'll note loose siding, chalky paint, or cracked concrete (with photos) before you start.
• Weather and timing. That rain or wind can move the date, and how long the quote is good for.
• How to book and pay. A signature line or "reply yes to book", when payment is due, and the ways you take it.

Pressure washing pricing questions

How much should I charge per square foot for pressure washing?

Work it out from your own costs and speed. Find what each crew-hour has to bring in (the free pricing calculator helps), then time how many square feet an hour your crew cleans on each surface. Your rate per square foot is that hourly number divided by the square feet per hour. Concrete with a surface cleaner usually goes faster than a two-story soft wash or a weathered deck, so each surface gets its own rate. The rates on this page are made-up samples so the calculator works right away. They aren't market prices, so type in yours.

How do I measure a house for a soft wash quote?

Measure the length of each wall, add them up, and multiply by the wall height to get square feet. Measure the height at a corner, or count the siding rows and multiply by the height of one row. Add the gable ends if you wash them (half the width times the peak height). You can leave windows and doors in the total, since washing around them takes time too. For driveways and patios, multiply length by width. For fences, measure the run in linear feet and decide whether you price one side or both.

Should I charge more for heavy mold, algae, or oil stains?

When it takes more time or more chemicals, yes. This calculator adds a condition surcharge to each surface line, so a north wall with heavy algae costs more without changing your base rate for the rest of the house. Show it on the quote as its own amount so the client sees why. Some stains (rust, oil, tannin, paint) fade but don't come out all the way, so say that on the quote before you start. The surcharge percents here are made-up samples.

Should repeat clients get a discount?

A small repeat-service discount can turn a one-time wash into a client you see every year. Here it comes off the surfaces only, so add-ons like gutters and sealing stay at full price. Set the discount to 0% for any schedule where you don't want one. The sample discounts (5% once a year, 10% twice a year, 15% every 3 months) are made up.

What minimum charge should I set for a small job?

Enough to cover driving out, setting up, and packing up, plus your time on the job. One way to set it: time a small job from leaving the last stop to leaving this one, and multiply by your hourly target. Any quote below the minimum is raised to it, and the calculator shows the raise as its own line. The $175 in the sample is made up.

Do I charge sales tax on pressure washing?

It depends on your state, and sometimes your city or county. Some places tax cleaning services and some don't. Check with your state's revenue department or an accountant, then type your rate in step 3, or leave it blank if you don't charge tax. This is general information, not tax or legal advice.
