Pricing and estimating

How to price pressure washing jobs

Price pressure washing from your own production rate: how many square feet a crew cleans per hour on each surface, times your loaded hourly cost, plus chemicals, travel, and a minimum charge that covers every truck roll.

To price a pressure washing job, measure the surface, divide it by how many square feet your crew cleans per hour on that surface, multiply the hours by your loaded hourly cost, then add chemicals, travel, and setup. Add overhead and profit on top, and never quote below your minimum charge. Most washers sell the result as a price per square foot or per linear foot, but the per-foot rate has to come from hours, because time is what you are really selling.

The trap is copying a per-square-foot number from a forum or a competitor's yard sign. A flat, open driveway and a stained deck with 40 balusters can have the same square footage and take very different amounts of time.

Pricing methods pressure washers use

  • Per square foot. The standard for driveways, patios, pool decks, and parking areas. Simple to measure from a satellite image or a tape, easy for a customer to compare.
  • Per linear foot. Used for fences, gutters (face cleaning), curbs, and roof edges. Price fences by linear foot at a given height, and charge more for both sides.
  • Flat rate by house size. Common for house washing (soft washing siding). Bands such as one story under 2,000 square feet, two story, and so on, built from your average hours per band.
  • Hourly. Good for commercial work with unknown conditions, graffiti, equipment, and heavy grease. State the hourly rate, the minimum hours, and what counts as billable time.
  • Recurring contracts. Storefronts, drive-throughs, dumpster pads, and HOA common areas cleaned monthly or quarterly. Priced per visit with a small discount for the commitment, which smooths out your slow months.

Step by step: building the price

  1. Measure. Square feet of flatwork, wall area or footprint for houses, linear feet for fences and gutters. Note stories, access, and anything that slows the crew: plants to protect, furniture to move, oil stains, rust, or a long hose run.
  2. Pick the production rate. Use your own numbers per surface: square feet per hour with a surface cleaner on concrete, per hour on a soft wash, per hour on wood. Track them for a month if you do not have them yet. See how to estimate labor hours.
  3. Cost the labor. Hours times the burdened hourly cost of the crew, not the wage. Payroll taxes and workers' compensation sit on top. See labor burden.
  4. Add chemicals and consumables. Sodium hypochlorite mix, surfactant, degreaser, rust remover, sealer if you offer it, plus tips and wear parts.
  5. Add equipment cost. Fuel, rig maintenance, and a per-hour charge that pays back the pressure washer, surface cleaner, trailer, and water tank over their life. See how to price equipment costs into a job.
  6. Add travel and setup. Drive time, unloading, protecting plants, and cleanup. On small jobs this is often half the total time.
  7. Load overhead and profit. Insurance, phone, marketing, software, the truck payment, and your own salary, then margin. See how to calculate construction overhead rate.

Worked example: a driveway and house wash

This is a made-up example to show the math. The rates are placeholders, not market prices, so replace them with your own production rates and costs.

Say a homeowner wants a 1,000 square foot concrete driveway cleaned and a one-story house soft washed. Your tracked production on open concrete with a surface cleaner is 800 square feet per hour, so the driveway is 1.25 hours. Your average one-story soft wash takes 2.5 crew hours. Setup, travel, and cleanup add 1.25 hours. Your loaded crew cost is $55 per hour for a two-person crew sharing one rig.

Example: driveway plus one-story house wash
ItemQuantityRateCost
Driveway cleaning labor1.25 hours$55 per hour$69
House soft wash labor2.5 hours$55 per hour$138
Travel, setup, cleanup1.25 hours$55 per hour$69
Chemicals and consumablesLot$35
Equipment and fuel5 hours$12 per hour$60
Direct cost$371
Overhead at 25% of direct cost$93
Cost including overhead$464
Sell price at 20% net margin ($464 / 0.80)$580

Notice what happens if you quote the driveway alone. Its cleaning time is only 1.25 hours, but the truck still has to drive out, set up, and pack up. That is why the driveway on its own needs a minimum charge, and why bundling a driveway with a house wash or a patio is the easiest margin in the business.

Minimum charge, overhead, and markup

Set a minimum job price that covers one full trip: drive time both ways, setup, cleanup, chemicals, and the office time to book, confirm, and invoice. Below that number you are paying to work. Many washers also set a minimum for add-ons (a single walkway, one fence section) so small upsells still carry their share.

Overhead in a pressure washing company is mostly fixed: insurance, the truck and trailer, phone and marketing, software, and your own pay. Spread it across the hours you realistically bill in a year, not the hours you hope to bill. If you only wash 25 weeks a year in a cold climate, your overhead per billable hour is much higher than a washer in Florida, and your prices should show it. Then decide on margin, not markup: markup vs margin in construction explains the difference.

Adjusting the rate for the job

  • Surface. Concrete with a surface cleaner is fast. Wood decks, pavers with joint sand, and stucco need lower pressure and more care, so production drops.
  • Condition. Heavy mildew, oil, rust, or years of buildup can double the time. Price stain treatment as a separate line so the customer sees why.
  • Height and access. Two-story houses, steep lots, and long hose runs slow everything down. Add a height or access adder rather than hiding it.
  • Water. If you must bring water or the site has low flow, add the time and the tank wear.
  • Painted surfaces on older homes. If washing will strip or disturb paint on a home built before 1978, EPA's lead Renovation, Repair and Painting rules may apply, which means certification and lead-safe work practices. Check before you quote, and price the extra containment if it applies.

Commercial and recurring work

Commercial customers buy reliability. A restaurant chain wants the drive-through and dumpster pad cleaned on schedule, at night, with a photo after every visit. Price those per visit from your hours plus a night premium, and put the frequency, scope, and payment terms in a service agreement. Commercial jobs often pay on net terms, so plan for the wait; how to forecast cash flow shows how. Check local stormwater rules about where wash water can go, because some cities and property owners require recovery or require you to keep runoff out of storm drains.

Check your prices against real jobs

After each job, compare the estimated hours with actual hours by surface. If your two-story house washes keep running 30 percent over, raise that band. This is job costing at a small scale, and it is what keeps per-square-foot prices honest. Smart Business Automator tracks estimated against actual cost on each job and turns the approved quote into the invoice, so the numbers do not live in a notebook.

Frequently asked questions

Should I charge by the square foot or by the hour for pressure washing?

Quote customers per square foot, per linear foot, or a flat rate, but build those numbers from your hourly cost and tracked production rates. Use hourly pricing for jobs with unknown conditions, like heavy grease or graffiti.

What is a minimum charge in pressure washing?

It is the lowest price you accept for any job, set high enough to cover a full trip: drive time, setup, cleanup, chemicals, and office time. Small jobs priced below it lose money even when the per-foot rate looks fine.

How do I price house washing?

Most washers use flat rates by size band, such as one story or two story by square footage, built from their average hours for each band. Add adders for heavy mildew, difficult access, or extra height.

Should chemicals be a separate line on the estimate?

They can be built into the per-foot rate for routine work. Price special treatments, such as rust or oil removal and sealing, as separate lines so the customer sees what they are paying for.

Do lead paint rules apply to pressure washing?

They can. If the work disturbs painted surfaces on homes built before 1978, EPA's Renovation, Repair and Painting rules may require firm certification and lead-safe practices. Check EPA's guidance before quoting that work.
