Pressure Washing

The before-and-after is so good it sells the next job.

Around $250
Hard

Driveways go gray. Decks go green. Sidewalks get that grimy film nobody notices until it's gone. You wash it off and the difference is so obvious that the before-and-after photo does your selling for you. It's satisfying work, it pays well by the hour, and it's the closest thing in this deck to a business you can see from the street.

Start for free

Wash something for free and photograph it

Start with your own driveway, or a neighbor's, using a borrowed or rented machine. Do half of it, stop, and take the photo with the clean half next to the dirty half.

Then show that photo to fifteen houses on your street:

"I pressure wash driveways and walkways. That's the one I did on Maple. It's [your price] for a driveway like yours. Want me to do yours this weekend?"

Book three jobs before you buy a machine. Three jobs at real prices covers most of what the machine costs.

The plan

Your simple plan

  1. Price by the job, not the hour. Measure the driveway, quote a flat number. Customers hate an open clock.
  2. Start with flat concrete only. Driveways, walkways, patios. Skip siding, roofs, and anything above your head until you're experienced.
  3. Use a surface cleaner attachment. It's faster, and it prevents the zebra striping that makes an amateur job obvious.
  4. Always shoot before and after. Every job feeds your next three. This business markets itself if you let it.

Safety comes first on this one

A pressure washer is not a hose. At full pressure it will cut skin, tear siding, etch concrete, and blow a window seal. It kicks back hard. This is a 16-and-up idea, and even then, get a parent to go through the manual with you and watch your first job. Wear eye protection and closed shoes every time. Never point it at a person, ever, including as a joke.

Skip these for now
  • A gas commercial unit. More power, more danger, more money, and you don't need it yet.
  • Surface sealing services. Different skill, different liability.
  • Roof or gutter work. Ladders plus water pressure is how people get hurt.

The lesson from the book

Andre's dad worried about the business for a reason. He'd watched a business fail up close, and his caution came from caring, not from doubting Andre. This is the idea in the deck where that caution is genuinely useful. Real equipment, real risk, real money. So bring your parents in as partners on this one, not as obstacles. Show them the numbers, show them the safety plan, and let them be the second set of eyes. That's not asking permission. That's how grown-up businesses actually run.

What should a kid charge to walk a dog?

A kid walking dogs in their own neighborhood usually starts between $10 and $18 for a thirty minute walk. Professional walkers average about $21 for the same walk.

How much money does a kid need to start a business?

Less than almost anyone expects, and for a lot of these ideas the honest answer is nothing until somebody has already said yes to a price.

Read the answer

How does a kid find their first customer?

Ten people who already know them, one prepared sentence, and an easy way for each of them to say no.

Read the answer

What do I do when my kid wants to quit?

Find out whether this is not working or just not fun right now. Those look identical from outside and they need opposite responses.
