When you bid commercial pressure washing contracts, the part of the job that decides whether you make money happens before you ever pull a trigger. A residential wash is mostly a known quantity: you can see the whole house from the driveway, you quote it on the spot, and the homeowner pays the day you finish. A commercial property hides its costs. The square footage is larger than it looks, the access is worse than it looks, the water and the wastewater both become real problems at that scale, and the customer pays on a thirty or sixty day cycle that you have to carry. Pricing that the way you price a driveway is how an operator wins the bid and loses on the contract.
Why a commercial bid is a different document
A residential quote answers one question: what will it cost to wash this house once. A commercial bid answers four. What will it cost to wash this property once, how often will you do it, what does the property owner need to see before they can hire you, and how is the price going to hold up over a twelve month term. Skip any one of those and the bid either loses to a more complete proposal or wins at a number you regret by the second visit.
The frequency question is the one that separates commercial work from everything else. Most commercial pressure washing is recurring: a retail center wants the sidewalks and entrances done monthly, a restaurant wants the dumpster pad and drive-through done on a set cycle, a property manager wants the building exterior soft washed once or twice a year. That recurring schedule is the prize, because it is predictable revenue you do not have to resell every week. It also changes the pricing, because a property you visit twelve times a year should not carry the same per-visit setup cost as a one-time job, and because the property owner is comparing your annual number against other annual numbers, not your visit against a competitor's visit.
The other thing that makes it a different document is who reads it. A homeowner reads a price. A facility manager reads a price, an insurance certificate, a scope that names exactly which surfaces are included, and a line that tells them you will not leave their wash water running into the storm drain on their property. The bid that answers the manager's checklist before they have to ask is the bid that gets shortlisted.
The site walk that turns a property into a number
You cannot bid a commercial property from a satellite image. The walk is where the real number lives, and it is worth the trip even when the prospect wants a price over the phone. Measure the actual square footage of every surface in scope with a wheel or a laser, because a parking lot or a sidewalk system is almost always larger than an eyeball estimate, and you are about to multiply that number by twelve visits. Note the surface for each area, because concrete flatwork, building exterior, and a grease-soaked dumpster pad are three different jobs with three different methods and three different speeds.
Then look for the things that slow a crew down, because labor is most of your cost and these are what move it. Where is the water, and is there a spigot you can use or do you need to bring a buffer tank. Where can the wastewater go, and is there a landscaped area or an approved connection, or will you have to capture and haul it. How is the access: are you working around parked cars and customers, which means night or early morning work, or is the lot clear. Is any of it up high, which means lift time and a different risk profile. What is already stained or damaged, which you photograph now so a pre-existing crack does not become your claim later. Each of these is a line on your worksheet, and together they turn a flat square footage into a real labor estimate.
A useful habit on the walk is to separate the property into the surfaces you will pressure clean and the surfaces you will soft wash, the same sort the guide to pressure washing damage claims walks through, because that split drives both your speed and your liability. The dumpster pad and the flatwork take pressure and degreaser. The building exterior, the awnings, and anything painted or coated take a soft wash. Quoting the wrong method for a surface is the fastest way to turn a profitable contract into a repair bill.
Build the bid from your crew-hour cost
Here is the move that keeps you out of trouble: do not start from a price per square foot. Start from what one hour of your crew on site costs you, then estimate how many hours the property takes, then add your materials, your overhead, and your margin. The square foot rate is what you get at the end. It is an output you can sanity check, not an input you copy.
Start with labor, because it is the largest line. The U.S. Bureau of Labor Statistics put the median wage for janitors and building cleaners, the closest national category for this kind of work, at $17.27 an hour in May 2024.1 That is the wage, not the cost. The cost of an hour of labor includes the payroll taxes you owe on top of the wage, workers' compensation, and any benefits, which together commonly add a third or more to the base wage. A worker you pay $18 an hour costs you closer to $24 or $25 an hour once the burden is on. Run a two-person crew and your loaded labor alone is roughly $48 to $50 an hour before the machine has burned a drop of fuel. Use your own numbers here, but use loaded numbers, because the wage by itself is the figure that quietly underprices the bid.
Then add the cost of the machine and the truck for that hour: fuel for the rig and the hot water burner, the wear on the equipment, and a share of what the truck and trailer cost you to own and insure, spread across your billable hours. Add a small consumables figure for the tips and fittings that wear out, which is easy to forget and real over a year. Now you have a loaded crew-hour cost. Multiply it by the hours the site walk told you the property takes, add your chemistry, add a share of your fixed overhead, and add the margin you intend to keep. Only now do you divide by the square footage to see your effective rate, and check it against what you know commercial flatwork tends to go for, often somewhere in the range of fifteen to fifty cents a square foot depending on the surface and the region, a rough market feel rather than a rate to price from. If your cost-built number lands far below that range you have probably missed a cost. If it lands far above, the property may be slower or more chemical-heavy than a typical job, which is worth confirming before you send it.
This is the same logic the pressure washing pricing guide uses for residential work, scaled up. The difference is that on a commercial property the hours are larger and the mistakes compound across every visit in the contract, so getting the crew-hour cost right matters more, not less.
The lines a commercial bid needs that a residential quote skips
A residential quote can be four lines. A commercial bid carries a few more, and each one exists because a commercial property creates a cost or a requirement a single house does not.
The first is wastewater containment and disposal. At residential scale you can often let rinse water soak into a lawn. At commercial scale you are usually washing acres of impervious surface that drains straight to a storm inlet, and that water is a regulated discharge. Section 402 of the Clean Water Act prohibits putting that wash water into a storm sewer system without a permit, and the compliant options are to capture and contain it, evaporate it, or send it to an approved sanitary connection with the property's permission.2 That is real labor and real equipment, so it belongs on the bid as its own visible line rather than buried in the wash price. The full legal picture, the methods, and what each one costs are covered in the guide to pressure washing wastewater disposal; for the bid, the point is that a facility manager who knows the rules expects to see containment on the proposal, and its absence reads as an operator who is going to create a problem on their property.
The second is a chemistry line. Commercial work leans harder on degreasers for dumpster pads and drive-throughs, and on soft-wash detergents for building exteriors, than most residential jobs do. Those chemicals cost money, change your disposal handling, and sometimes require pH adjustment before discharge, so a separate surcharge that scales with the chemistry the property needs keeps the wash price honest.
The third is not a price line at all, it is insurance, and it can disqualify you before the price is even read. Commercial and municipal contracts routinely require a minimum general liability limit, often stated as a million dollars per occurrence, and a certificate of insurance naming the property owner or manager as an additional insured. Confirm what each contract demands and that your policy meets it before you spend time on the bid, because a sharp price you cannot insure to the required limit is a wasted afternoon.
Contract terms that protect a recurring agreement
A one-time wash is over when the customer pays. A twelve month contract has to survive a year of cost swings and scope creep on a payment cycle you do not control, so the terms are part of the bid, not paperwork you sort out later.
State the frequency and what each visit includes in plain language, so monthly sidewalk and entrance cleaning does not slowly turn into the whole property every time someone asks. Put in a scope-change procedure that says added areas or added frequency are priced separately and approved in writing before the crew does the work, which is what stops the "while you're here" requests from becoming free labor. For a longer agreement, include a price escalator, a stated way the rate can adjust at renewal or if fuel and chemical costs move past a threshold, so you are not locked into today's costs for two years.
Then set the payment terms deliberately, because this is where commercial cash flow either works or hurts. A property manager pays on a cycle, which means net terms are usually unavoidable on commercial work, and the net-thirty standard most accounts expect traces back to the federal Prompt Payment Act, which directs agencies to pay their vendors within thirty days of a proper invoice.3 Net terms are the cost of doing commercial work, but they are a cost you should price for and bound. Decide whether the contract is net fifteen, net thirty, or net forty-five, write the due date as a real date on every invoice rather than a vague label, and the same way you would set terms on any account, covered in the guide on what payment terms to put on an invoice, hold a late fee in reserve for the manager who lets ninety days go by.
A worked example: a 40,000 square foot retail center
The numbers below are illustrative, chosen to show how the cost build works rather than to quote a market rate. Use your own loaded costs and your own production speeds.
A property manager wants monthly cleaning of the common sidewalks and the two entrances at a strip retail center, plus a quarterly degrease of the shared dumpster corral. The site walk measures about 12,000 square feet of sidewalk and entrance flatwork in monthly scope. The crew runs a surface cleaner on open flatwork at a planning rate of roughly 3,000 square feet an hour, so the flatwork is about four crew hours, and detail work around the entrances and bollards adds an hour, for five crew hours a visit. Loaded labor for a two-person crew at $50 an hour is $250. The machine and fuel for those hours add about $60. Chemistry for the monthly visit is light, call it $25. That is $335 in direct cost. Add a share of overhead and the margin you intend to keep, say 45 percent on top, and the monthly visit prices at roughly $485, which works out to about four cents a square foot on the cleaned area for a recurring sidewalk wash. The quarterly dumpster degrease is priced as its own visit, with its heavier chemistry and a containment line because that pad drains to the lot, at roughly $220 a visit.
The annual contract value is twelve monthly washes at $485 plus four degreases at $220, which is $5,820 plus $880, or about $6,700 a year. Now the terms do their job. The bid states monthly and quarterly scope separately so nobody assumes the dumpster pad is included in the sidewalk visit, names the containment on the degrease line so the manager sees you handle the wastewater, sets net thirty with a real due date, and includes a fuel-and-chemical escalator at the twelve month renewal. That is a defensible recurring contract built from cost, not a number guessed off a per-square-foot chart and regretted by spring.
When to walk away from a bid
Not every commercial property is worth winning, and the discipline to walk is part of bidding well. Walk away when the property cannot give you a legal place to put the wastewater and the capture-and-haul cost makes the job a loser, unless the customer will pay for it on a line they can see. Walk away when the required insurance limit is above what you carry and raising it costs more than the contract returns. Walk away when the manager wants a residential price for a commercial property, because a number that ignores the access and the wastewater it has to handle is a number that loses money twelve times a year. And walk away from the bid that only pencils if every visit goes perfectly, because commercial work, run monthly across a year, will not.
The bids worth chasing are the ones where the site walk gave you a real hour count, the cost build left you a margin you can defend, the property has a clean way to handle the wash water, and the customer is buying a recurring relationship rather than the lowest possible number. Those are the contracts that turn one good month into predictable revenue, which is the entire reason commercial work is worth the extra document.
Put every surface and its disposal on one approved page
We built EosLog's quote generator so a commercial pressure washing bid goes out as an itemized scope that names each surface, the method, the containment, and the disposal on a single page the property manager approves before you start. The same scope you bid from becomes the record you invoice against on every visit in the contract.
