How to get commercial pressure washing contracts that recur

Residential pressure washing is often one visit a year per customer. Commercial washing can be the same property every month for years: the sidewalk in front of a grocery store, the drive-thru lane at a restaurant, the dumpster pad behind a strip center, the stairwells of a parking garage. The buyer is often a manager responsible for several sites who may live in another city and judges your work from photos and complaints. Win those buyers and your schedule fills with recurring stops you can route around.

This guide covers who buys commercial washing, how they hire, what they'll ask for, how to handle wash water, how to price and scope the work, how to prove it was done, how to find accounts without buying leads, and how federal and public contracts work. Our pressure washing industry page covers the trade itself. This is general information, not legal or environmental compliance advice. Stormwater, licensing and purchasing rules vary by state and city.

Who buys commercial pressure washing?

The common thread is recurrence. A property that needs its sidewalks cleaned once a month and its dumpster pad once a quarter is worth far more over three years than a single big wash.

How do facility managers hire pressure washers?

Local managers usually hire directly: they get a few quotes, check insurance and pick a vendor. Multi-site operators, such as restaurant and retail chains, often work differently. Some run their own vendor networks with regional managers, and some hand the work to facility management companies that subcontract to local vendors. When you work through one of those layers, expect:

• Work orders with a not-to-exceed amount. Going over it requires approval before you do the work.
• Check-in and check-out rules, often through the manager's own app or phone system, with time stamps.
• Photo requirements for before and after, sometimes for specific angles or areas.
• Invoicing through a portal, with the work order number on each invoice and payment on the manager's terms.
• Compliance documents uploaded and kept current: insurance certificates, W-9 and sometimes safety training records.

Before the first work order, read the subcontractor agreement closely, especially the payment terms, any fees charged to vendors, the indemnity section and what happens when a job is disputed. Work out what you actually net per visit after any fees and the wait for payment, and compare it with a direct contract; a network can fill gaps in your schedule when the terms hold up. For the day-to-day relationship, read how to work with property managers.

What will a commercial buyer ask you for?

• Certificate of insurance. Limits set by the client, often with the owner and manager named as additional insured. Tell your agent you work on commercial properties, at night, with chemicals and with water recovery, so the policy fits the work. See our contractor insurance guide.
• W-9. The IRS form that gives the client your taxpayer ID for the information returns it files on payments to you.
• Safety data sheets for degreasers, surfactants and any acid or bleach products. OSHA says employers with hazardous chemicals in the workplace must have labels and safety data sheets and train workers to handle them. On a client's property, the multi-employer rule in 29 CFR 1910.1200(e)(2) expects you to tell the other employer how its people can get those sheets.
• A wash-water plan. What you do with runoff on that site. More on this below.
• Night work details. Lighting, cones, how you handle cars left in a lot, noise limits and who has the gate code.
• Water source. Whether you'll use the property's spigot or bring your own water, and what that does to the schedule.

Where does the wash water go?

Dumpster pads, drive-thrus and parking garages put grease, oil and food waste into your rinse water, so where that water goes is part of the job. The EPA explains that polluted runoff is commonly carried through municipal storm sewer systems and then often discharged, untreated, into local water bodies. Under federal stormwater rules for smaller municipal systems, the permit must require the city or other operator to effectively prohibit, through ordinance or another regulatory mechanism, non-storm water discharges into the storm sewer system to the extent state, tribal or local law allows, and to inform businesses about the hazards of illegal discharges.

What that means in practice is set locally. Before you bid a commercial site:

1. Call the city's stormwater, public works or environmental office and ask what they require for commercial pressure washing, especially grease, oil and chemical-laden water.
2. Ask the local sewer authority whether and how recovered wash water may go to a sanitary drain on the property, and what pre-treatment it expects.
3. Write the answer into your bid: drain covers or berms, recovery vacuum, filtration, where recovered water goes, and the time it adds.

How do you price commercial pressure washing?

Survey first. Walk the property, ideally at the time of day you'd do the work, and record:

• Each zone to be cleaned and its square footage: sidewalks, entries, drive-thru lane, pads, canopy undersides, walls.
• Surface type and condition: broom-finish concrete, pavers, brick, painted or coated surfaces, oxidized metal.
• Stains you'll be asked about: gum, grease, rust, tire marks, efflorescence. Photograph them.
• Water and power access, drain locations, slope, and where runoff goes.
• Traffic and hours: when the lot empties, when deliveries arrive, when the drive-thru closes.

Then price each zone from your own production rates, in square feet per hour for that surface with your equipment, plus setup and breakdown, water recovery time, chemicals, travel and any night or weekend premium you charge. Add the zones into a per-visit price for each frequency. Our pressure washing pricing guide covers the per-square-foot method, and the job price calculator turns your costs and margin into a price.

Present it as a program with a schedule, for example:

A program priced per visit, with a twelve-month calendar, is easier for a manager to budget and approve than a list of separate quotes, and it gives you a schedule you can route.

What belongs in the scope and contract?

• A zone map with each area numbered and its frequency listed.
• Service windows: which hours and days you may work, and how much notice you give before each visit.
• What clean means, and what it doesn't. Name the stains you can lighten but not promise to remove (deep oil, rust, old gum shadows, efflorescence) and surfaces you won't high-pressure.
• Pre-existing conditions: a dated photo log of cracks, spalling, loose pavers, faded paint and damaged signs from the survey.
• Weather and temperature: when a visit is rescheduled and how quickly it's made up.
• Water, power and recovery: who supplies what and how wash water is handled.
• Extra work approval: who can approve it, in writing, and up to what amount.
• Payment and term: invoice timing, payment terms, contract length, renewal and termination notice.

Our service contract checklist covers the standard clauses. A one-time review of your template by a local attorney is money well spent.

How do you show the work to a buyer who never visits?

The regional manager for twenty restaurants may never stand on your dumpster pad. What they see is your report. Make it the best part of your service:

• Before and after photos of each zone, from the same spot and angle every visit, as our before-and-after photo guide explains.
• Arrival and departure times captured on site, by property.
• Each zone checked off, with notes on anything that couldn't be done (a car parked over the stain, a locked enclosure).
• Issues spotted: broken drain grates, overflowing dumpsters, damaged bollards, trip hazards, each with a photo.
• The report sent to the manager the same night or the next morning.

Sent on time, every time, that report answers "did they come?" before it's asked, and each issue you flag becomes a priced proposal the manager can approve. A CRM that stores visits, photos and checklists by property and zone can assemble the report and attach it to the invoice. That's what our custom CRM is built to do. We use the same kind of system in our own companies.

How do you find commercial accounts with channels you own?

• A commercial page on your website listing the surfaces you clean, your recurring programs, your water recovery setup and a request-a-site-survey form, with dated commercial before-and-after photos. Our website service builds pages like this; pressure washing SEO explains how they rank.
• The plazas you drive past. Look for dirty sidewalks, stained drive-thrus and grimy dumpster pads near your current stops. Note the management company on the leasing sign and call to ask who handles exterior cleaning.
• Restaurant and store managers. The manager on duty often can't sign a contract, but can tell you who does and pass along your one-page program.
• Community managers. CAI counts community managers and association management firms among its members, so a local chapter is a direct line to the people who budget HOA washing.
• Builders. General contractors need concrete and masonry cleaned before turnover. Ask their superintendents who handles it.
• Email and calls, done right. The FTC's CAN-SPAM guide says no exception exists for business-to-business email, so every outreach email needs your postal address and an opt-out you honor.

How do public and federal washing contracts work?

Cities, counties, transit agencies and school districts bid exterior cleaning under their own purchasing rules, which differ from one agency to the next. Watch their bid portals, register as a vendor, and read the insurance, bond, wage and environmental sections of each bid before pricing it.

For federal contracts, the pieces from the agencies' own sites, as read in October 2026:

• Classification. The Census Bureau's 2022 NAICS index places power washing building exteriors, pressure washing of buildings, decks and fences, and parking lot cleaning by power sweeping or washing under 561790, Other Services to Buildings and Dwellings. In 13 CFR 121.201, current on October 5, 2026, SBA's size standard for 561790 is $9.0 million in average annual receipts. The contracting officer picks one NAICS code per solicitation, with an exception for some multiple-award contracts (13 CFR 121.402), so a washing job folded into a larger facilities contract may use a different code and size standard.
• Registration. Per the SBA, you need a Unique Entity ID, which SAM.gov assigns at registration. GSA's checklist says getting it, registering and maintaining the registration carry no charge. Renew yearly; SAM.gov sets the cycle at 365 days.
• Where notices appear. The SBA says agencies must post contracts over $25,000 on SAM. It also keeps a directory of large prime contractors with subcontracting plans, which is one way into work on big facility contracts.
• Wage rules. The Service Contract Act requires prevailing wages and fringe benefits for service employees on covered contracts above $2,500, according to the Department of Labor. DOL's regulations say covered service contract types are too numerous and varied to list completely, so check each solicitation for a wage determination.
• Certifications. If your company qualifies, SBA certifications such as 8(a), WOSB, HUBZone and SDVOSB open contracts reserved for certified firms. When a certified HUBZone firm bids in an unrestricted competition, for instance, SBA says its price gets a 10% evaluation preference.
• Payment timing. Unless the contract says otherwise, the Prompt Payment rules generally make payment due 30 days after a proper invoice arrives.

How do you keep recurring commercial accounts?

• Never miss a scheduled visit without warning. If weather or equipment pushes you, tell the manager before the date, with the makeup date.
• Keep the same crew on the same properties so they learn the stains, the drains and the gate codes.
• Review the program every quarter. Send a short summary with photos showing how each zone has held up, and suggest changes in frequency where the property needs more or less.
• Offer what you actually do well. Window cleaning, gutter cleaning or sealing can ride along on the same visit if you're equipped for it. Don't sell services your crew hasn't done before on a client's storefront.
• Ask for the next site. Managers with one property often have more.
