How to Quote a Pressure Washing Job

Quoting a pressure washing job comes down to three numbers: the square footage, your per-square-foot rate for that surface, and your minimum charge. Measure the area, multiply by the surface rate — $0.15–$0.35 for concrete, $0.20–$0.40 for siding, $0.25–$0.50 for wood decks, $0.30–$0.60 for roof soft washing — then apply your $125–$200 minimum so small jobs stay profitable. Adjust up for heavy mold, multi-story work, and delicate surfaces, and send the quote the same day. That is the whole system. Everything below is how to execute it without leaking money.

2026 pressure washing rates by surface

Price by the square foot, not by the hour. Clients understand square footage, it scales cleanly, and it rewards you as you get faster. These are 2026 US residential ranges — new operators start at the low end to win reviews; established pros with photos and insurance charge the top end without apology.

Notice the pattern: the gentler the method, the higher the rate. Soft washing looks easier than blasting concrete, but it requires chemical knowledge — sodium hypochlorite ratios, surfactants, dwell times — and clients pay for expertise, not effort. Price the knowledge.

What typical jobs actually price at

Square-foot rates are the input; job totals are what clients compare. Here is what the math produces on standard residential jobs at mid-range rates:

Bundling is where the money is. A standalone $150 driveway barely covers the trip; a $550 house-plus-driveway package on the same visit doubles your hourly rate because setup, travel, and teardown happen once. Always quote the bundle alongside the single service — most clients take it.

Step 1: Measure the area

Pace it off or use a measuring wheel — length × width for driveways and patios, wall length × height for siding. For houses, measure each wall separately and add them up; subtract nothing for windows at quote stage, since the wash passes over them anyway. You don't need survey precision — within 10% is fine for quoting, because your minimum charge and rate ranges absorb the error.

Time estimate while you're measuring: figure roughly 300–500 sq ft per hour depending on soil level. A standard 2-car driveway (400–600 sq ft) takes 1–2 hours including setup and teardown. Use that to sanity-check your price — if the math says $140 for three hours of work, your rate is too low or the minimum needs to kick in.

Step 2: Identify the surface and method

This is the step that separates pros from guys with a Home Depot machine. The surface dictates the method, and the method dictates the rate — and the liability.

• Pressure washing (2,500–4,000 PSI): concrete, brick, pavers. The machine does the work.
• Soft washing (100–300 PSI + chemicals): siding, roofs, stucco, painted surfaces. The detergent does the work; water just rinses. Typical mix: 1–3% sodium hypochlorite with a surfactant, 10–15 minute dwell time.
• Low-pressure wood cleaning (500–1,200 PSI): decks and fences. High pressure furs and splinters wood — one gouged deck costs more than the job paid.

Never pressure-wash an asphalt shingle roof. It strips granules and voids the manufacturer warranty — soft wash is the only acceptable method, and it commands the highest rate on the menu. If a client asks for high pressure on a roof, that's your cue to educate, not comply.

Step 3: Apply your rate, then your minimum

Multiply area by the surface rate. Then compare against your minimum charge — $125–$200 is the 2026 standard — and quote whichever is higher. The minimum is the step beginners skip, and it is where they lose money: a 200 sq ft walkway at $0.25/ft is $50, which doesn't cover fuel, unloading, setup, the wash, teardown, and the drive home. Put the minimum on every quote. Clients expect it; every trade has one.

Set the minimum based on your real costs: fuel and vehicle wear to reach your average job, 30–45 minutes of setup/teardown, and your target hourly rate. If your numbers say $140, set $150 — round numbers quote cleaner.

Step 4: Adjust for conditions

The base rate assumes average soil on an accessible single-story surface with a working spigot. Reality adds surcharges — quote them as visible line items, not buried padding:

One warning on stain removal: never promise a stain will come out completely. Quote “stain treatment” as an attempt with a flat fee, and put “results vary” in writing. Rust and decade-old oil stains sometimes lighten but don't disappear — the surcharge covers your chemical and time either way.

Know your costs (so the rate means something)

A rate is only good if it clears your costs with margin. Per-job consumables on a typical $300 residential wash:

• Chemicals: $10–$25 (sodium hypochlorite, surfactant, degreaser)
• Fuel: $10–$20 (machine gas + vehicle)
• Water: $2–$5, or free from the client's spigot
• Equipment wear: $10–$20 amortized (pumps, hoses, nozzles, fittings)

That puts direct costs at roughly $35–$70 on a $300 job — before insurance ($500–$1,500/year), marketing, and your wage. Healthy residential margins run 50–70%. If yours don't, the rate is wrong, not the market.

Step 5: Present it like a pro and send it same-day

Speed wins pressure washing jobs — most clients take the first fair quote they get, and same-day quotes close at roughly double the rate of next-day ones. But speed without professionalism loses to the cheaper texted number. Your quote should show: the measured area, the per-square-foot rate, each line item (wash, treatment, extras), the total, a 30-day expiration, and proof of insurance on request.

Run the numbers through the pressure washing calculator, push it into the quote builder, and text or email the link before you drive away. Itemized beats flat every time — a $295 quote with visible lines beats a $250 texted number because the client can see what they're buying.

Pro tips from the trade

• Sell the house wash with every driveway. “While I'm here with everything set up, I can do the siding for $X” — the marginal time is small and the ticket doubles.
• Photograph everything before you start. Pre-existing damage (cracked siding, loose paint, etched concrete) becomes your fault if you can't prove it was already there.
• Downstream injectors over batch mixing for house washes — consistent chemical ratio, no stopping to remix, faster jobs.
• Recurring schedules are the real business. Annual house washes and biannual commercial flatwork turn one-time jobs into revenue you can forecast. Offer 10–15% off for a yearly agreement.
• Learn the fence staining bid too. Wash-plus-stain is the natural upsell — the wash preps the surface, and you're already on site with the customer's trust.

Costly mistakes to avoid

• Quoting hourly. You get faster; hourly punishes efficiency. Square footage rewards it.
• Skipping the minimum. Covered above — it's the difference between a business and an expensive hobby.
• High pressure on the wrong surface. Etched concrete, furred wood, stripped roof granules — each one is a repair bill bigger than the job.
• No photos, no notes. Disputes are won with timestamps.
• Forgetting the spigot question. Ask before you quote. Hauling water you didn't price is a margin killer.
• Working uninsured. One blown-out window or injured bystander without liability coverage ends the business.
