Commercial pressure washing costs $0.15 to $0.30 per square foot for a one-off visit and $0.10 to $0.20 on a scheduled contract. The bigger issue for most property managers isn't the rate — it's wash-water containment. Under the Clean Water Act, runoff carrying detergent, oil or food grease is a pollutant, and letting it reach a storm drain creates liability for the property owner as well as the contractor.
Below: how commercial pricing works, contract versus one-off, the containment rules in detail, scheduling around trading, what to check before signing a vendor, and frequency by property type.
Commercial rates explained
Commercial work is quoted two ways, and knowing which you're being given makes bids comparable.
Per square foot is standard for flatwork — sidewalks, parking areas, entryways, plaza walkways. Straightforward to compare across bids.
Fixed price per item is standard for defined units — a dumpster pad, a drive-thru lane, an awning run. These have a setup cost that doesn't scale with area, so per square foot pricing would be misleading.
| Scope | One-off | On contract | Notes |
|---|---|---|---|
| Flatwork — sidewalks, lots | $0.15 – $0.30 / sq ft | $0.10 – $0.20 / sq ft | Contract assumes quarterly minimum |
| Building facade soft wash | $0.20 – $0.40 / sq ft | $0.15 – $0.30 / sq ft | Up to three storeys from ground |
| Dumpster pad + degrease | $150 – $350 | $95 – $225 | Containment required |
| Drive-thru lane | $250 – $500 | $175 – $350 | After close only |
| Awning / canopy | $8 – $15 / linear ft | $6 – $12 / linear ft | Fabric tested first |
| Graffiti / emergency call-out | From $350 | From $250 | Same-day where possible |
Contract vs one-off
Contract pricing is roughly a third cheaper per visit, for two reasons that are worth understanding rather than just accepting.
Amortised setup. A significant share of any single job is travel, water hookup, containment setup and breakdown. Scheduled work spreads that across the year and lets a contractor route efficiently.
Less accumulated grime. This is the bigger one. A dumpster pad cleaned monthly needs a degreaser and twenty minutes. The same pad cleaned once a year has grease that's soaked into the concrete and needs hot water, aggressive chemistry and an hour — and it will never look as good, because some of that staining is now permanent.
The rule: reactive cleaning always costs more per year than scheduled cleaning, and delivers a worse result. If your current arrangement is "call someone when it looks bad", you're paying more for less.
Wash-water containment rules
This is the part that separates a genuine commercial contractor from a residential one with a bigger machine, and it's where property managers pick up unexpected liability.
Under the federal Clean Water Act, storm drains discharge to natural waterways without treatment. Anything entering them is a discharge to the waterway. Wash water carrying detergent, oil, grease or heavy metals is a pollutant, and discharging it without a permit is a violation.
In Jacksonville this matters practically rather than theoretically, because the municipal storm system discharges to the St. Johns River. Enforcement here is real.
Where containment is required:
- Dumpster pads and grease-trap surrounds — food waste and grease
- Drive-thru lanes — food, oil, tyre residue
- Fuel islands and service bays — hydrocarbons
- Parking structures — accumulated oil
- Any surface where a degreaser is being used
Where it usually isn't: plain water rinsing of an unstained sidewalk with no detergent. Even then, a competent contractor will berm the nearest drain as a precaution.
The method is straightforward: berms and drain mats to contain runoff, a vacuum to recover it, and disposal to sanitary sewer or a licensed facility. What matters is that your contractor does it and can document it — because if a violation is issued, the property owner is generally named alongside the contractor. Ask for the disposal method in writing.
Scheduling around trading
Almost all commercial exterior cleaning should happen outside operating hours, for three reasons: wet surfaces around customers are a slip liability, the noise is significant, and equipment and hoses across a walkway are an obstruction.
- Restaurants and QSR — after close. Drive-thru lanes especially; the lane needs to be empty and dry before the morning open.
- Retail plazas — overnight, typically 11pm to 5am.
- Office buildings — weekends.
- Medical and dental — before opening, and quietly.
- HOA common areas — weekday daytime is usually fine and is cheaper.
One practical note: after-hours work needs lighting and site access arranged in advance. Make sure whoever holds the keys or the gate code knows the crew is coming.
What to check before signing
- General liability of at least $1M, and $2M is the norm for larger properties. Request the certificate from the insurer directly, not a forwarded PDF, and ask to be added as additional insured.
- Workers' compensation for every technician. Without it, an injured worker can pursue a claim against the property.
- A written wash-water disposal plan for any surface with hydrocarbons or food waste.
- A defined scope. Which surfaces, what square footage, what's excluded. The cheapest bid is usually the one covering the least.
- Completion reporting. Photographs per visit, per site. Essential across a portfolio.
- References at similar properties — and actually call one.
How often by property type
| Property | Frequency | Why |
|---|---|---|
| Restaurant / QSR | Monthly | Grease accumulates fast and bonds to concrete |
| Retail plaza | Quarterly | Foot traffic, gum, spills; appearance drives footfall |
| Medical / dental | Quarterly | Entry cleanliness is part of the impression |
| Office building | Twice yearly | Lower traffic, mostly weather soiling |
| HOA / condo common areas | Twice yearly | Algae on walkways is a real slip hazard in Florida |
| Warehouse / industrial | Twice yearly | Loading bays and aprons collect oil and rubber |
My honest take
The single biggest saving available to most commercial properties isn't negotiating the rate down — it's moving from reactive to scheduled. We've taken over plazas where the previous arrangement was two emergency cleans a year at premium rates, and put them on quarterly for less total annual spend and a permanently better-looking site.
The thing I'd push property managers hardest on is containment, and it's the least interesting part of the conversation. If a contractor quotes a dumpster pad and doesn't mention where the water goes, that's not a bargain — that's a violation waiting to be issued with your entity's name on it. Ask the question. The answer tells you a lot about everything else they do.
Last thought: don't over-specify facade washing. Plenty of buildings get quoted for annual facade cleaning when the walkways and entry are what customers actually notice. Spend the budget where people look.
