Pressure Washing Quoting Mistakes That Cost You Money

Quoting is where you win or lose money on a pressure washing job, long before you ever pull the trigger on the wand. Price too low and you work all day for nothing. Quote too slow and the homeowner books the guy who called back first. After enough seasons in the field, you learn that most lost profit does not come from bad washing. It comes from bad quoting. Here are the pressure washing quoting mistakes that cost pros real money, and how to fix each one.

Mistake 1: Forgetting prep and setup time

Plenty of quotes only count the time spent actually spraying. But the job is more than the spray. You have drive time, setup, mixing chemicals, moving patio furniture, taping off outlets, pre-treating, post-treating, and breaking down. On a typical house wash, prep and setup can eat 30 to 45 minutes before you spray a single square foot.

When you only quote spray time, you quietly donate that prep hour to the customer. Across a full week, that is easily five or six unpaid hours. Fix it by building a flat setup charge into every quote, or by estimating total on-site time, not just wash time.

Mistake 2: Underpricing your overhead

This is the silent killer. Your hourly rate has to cover more than your labor. It has to cover insurance, truck payment, fuel, equipment wear, chemicals, software, phone, and the time you spend quoting and doing paperwork at night. A lot of guys set their rate based on what the competition charges, then wonder why there is nothing left at the end of the month.

Figure out your true cost to operate per hour, then add your target profit on top. If your competitor is cheap, that often means they forgot to do this math. Do not race them to the bottom.

A quick worked example

Say you want to quote a 2,000 square foot house wash. You price soft wash at 0.20 per square foot, so the base is 400 dollars. Now check it against your costs for that job:

• Labor: 3 hours on site, 2 crew, at 25 per hour each = 150 dollars
• Chemicals and fuel = 35 dollars
• Overhead allocation (insurance, truck, software, admin) at roughly 40 per hour of job time = 120 dollars
• Total cost = 305 dollars

At 400 dollars you keep about 95 dollars profit, or roughly 24 percent. That is healthy. But notice what happens if you forgot overhead and only counted labor and chemicals: you would think your cost was 185 dollars and feel comfortable discounting to 350. In reality that discount cuts your real profit nearly in half. Knowing your full cost keeps you from giving away margin at the door.

Mistake 3: Quoting too slowly

Homeowners who want their driveway or house washed are usually shopping three contractors at once. The first pro to send a clean, professional quote often wins, even at a higher price, simply because they look reliable and responsive. If your quote lands two days later, the job is already gone.

The problem is most crews quote at night from the truck or the kitchen table, exhausted, using a notes app and a text message. That delay costs you jobs you never even know you lost. Speed up the process by building a repeatable system: standard price list, templated quotes, and a way to send from your phone the moment you finish the walkthrough.

Mistake 4: No deposit and no clear terms

If you book jobs with zero money down, you are financing the customer's project. You buy the chemicals, burn the fuel, and block out the time, all on a handshake. Then one no-show or cancellation leaves you holding the bag. On top of that, a vague quote with no scope leads to arguments later: 'I thought the fence was included.'

Collect a deposit on anything larger than a quick single service. A 20 to 30 percent deposit is typical and reasonable. It filters out tire kickers, funds your materials, and commits the customer to the date. Spell out exactly what is included and what is not, so there is no fuzzy expectation on wash day.

• Take a deposit of 20 to 30 percent on larger jobs
• List what is included: surfaces, square footage, number of stories
• Note what is extra: gutters, screens, oil stains, heavy mildew
• State your payment terms and accepted methods up front

Mistake 5: Guessing instead of measuring

Eyeballing a job and throwing out a number feels fast, but it is how you end up upside down on big surfaces. A driveway that looks 'about average' might be 900 square feet or 1,400 square feet, and that difference is real money. Build your quotes on measured square footage and a per-surface price, with modifiers for condition.

1. Measure or estimate square footage for each surface: house, driveway, patio, deck.
2. Apply your per-square-foot rate for that surface type.
3. Add modifiers for heavy staining, oxidation, two-story access, or tough access.
4. Add your setup and travel charge.
5. Review against your true cost to confirm the margin is there.

When you quote this way, every estimate is consistent, defensible, and easy to explain to the customer. You stop leaving money on concrete you underestimated.

Mistake 6: Not following up

A quote that gets no follow-up is a coin flip. Many homeowners genuinely intend to book you but get busy, and a single friendly check-in a day or two later recovers a surprising share of those jobs. The contractors winning the most work are not always the cheapest. They are the ones who stay organized and keep the conversation going without being annoying.

Set a simple rule: every open quote gets one follow-up within 48 hours and another within a week. Track which quotes are still open so none slip through the cracks.

Bottom line

Most quoting losses are not dramatic. They are small leaks: forgotten prep, missing overhead, a slow reply, no deposit. Plug those leaks and your margins climb without washing a single extra house. Know your true cost per hour, quote fast and clear, take a deposit, and follow up. Do that consistently and you will out-earn the contractor spraying the exact same homes.
