Fleet Washing 101: How to Quote Your First Fleet Contract

Residential work is seasonal. Commercial work has long sales cycles. Fleet washing is a contract. A fleet manager with 40 box trucks needs those trucks washed every week or every two weeks, year-round. That is not a one-time job — it is a 52-week contract. The revenue is predictable, the scheduling is consistent, and the relationship is long-term. A 40-truck fleet washed biweekly at $35 per truck is $36,400 per year from a single client. Add a second fleet and you are at $70,000+ in annual recurring revenue before you wash a single house. The barriers to entry are low if you already run a power washing operation. You need a reliable rig, a basic understanding of vehicle-safe chemicals (no high-pH detergents on aluminum, no hydrofluoric acid on painted surfaces), and the ability to show up on schedule every time. Fleet managers do not care about your Instagram portfolio. They care about reliability, consistency, and not having their trucks damaged.

Fleet washing is priced per unit (per vehicle), not per square foot. The rate depends on the vehicle type, size, and condition. Here are baseline per-unit rates for common vehicle types based on 2025–2026 market data. Box trucks (16–26 foot): $30–$50 per wash. These are the most common fleet vehicle and your bread and butter. A standard box truck takes 10–15 minutes to wash. Semi trailers (53 foot dry van): $40–$65 per wash. Trailers take longer because of the size and the top. If the fleet wants tops washed, add $10–15 per trailer. Day cabs: $25–$40 per wash. Faster than box trucks because there is no box — just the cab and chassis. Sleeper cabs: $35–$55 per wash. Larger than day cabs with more surface area and usually more detail expected. Flatbeds: $20–$35 per wash. Less surface area, faster to wash, but you are dealing with whatever cargo residue is on the bed. Reefer trailers (refrigerated): $45–$75 per wash. The refrigeration unit on the front adds time and requires careful washing around electrical components. Tankers: $50–$80 per wash. Curved surface requires different technique and tankers often have chemical residue that needs specific handling. These rates assume a biweekly or weekly wash frequency. For monthly or quarterly washes where vehicles are significantly dirtier, increase rates by 25–50%.

A fleet quote has three components: per-unit rate multiplied by fleet size multiplied by wash frequency. That gives you the contract value. Then you check the margin. Here is a real example. A regional delivery company has 30 box trucks and 10 semi trailers. They want biweekly washing (26 washes per year). Box trucks: 30 trucks x $38/wash x 26 washes = $29,640/year. Semi trailers: 10 trailers x $52/wash x 26 washes = $13,520/year. Total annual contract: $43,160. Monthly billing: $3,597/month. Now check the margin. Each wash day, you are washing 40 vehicles. At an average of 12 minutes per vehicle, that is 8 hours of wash time for a two-person crew. Your crew-day cost (labor, chemical, fuel, equipment): $650. You are billing $1,520 per wash day ($38 x 30 + $52 x 10 = $1,660 per visit, but biweekly is every other week, so 26 visits). Revenue per wash day: $1,660. Cost per wash day: $650. Margin per wash day: $1,010 (60.8%). That is a solid fleet contract. The margin is healthy because the work is efficient — you drive to one location and wash 40 vehicles in a single session. No windshield time between jobs, no customer meetings, no estimates to send. You show up, wash, and leave. Volume discounts are expected on larger fleets. A 10-truck fleet pays full per-unit rate. A 50-truck fleet might get a 10–15% discount because the efficiency of washing that many vehicles at one location improves your margin even at the lower rate.

Fleet managers are not homeowners. They do not care about before-and-after photos or Google reviews. They care about three things: price, reliability, and professionalism of the proposal. Your fleet proposal should include a per-unit breakdown by vehicle type so the fleet manager can see exactly what they are paying for each truck, trailer, and cab. It should include monthly and annual pricing options — fleet managers budget monthly but think annually. Show both. Include the wash frequency and scheduling details — which days, what time window, estimated duration per visit. Include your insurance certificate information (fleet managers will request a COI before you start). And include your terms — payment net-30 is standard for fleet contracts, cancellation notice period (typically 30 days), and any seasonal adjustments. The proposal should look professional. A one-page text quote emailed from your Gmail is not going to win a 60-truck fleet contract. A branded PDF with your logo, clear line items, and professional formatting tells the fleet manager you run a real operation. In CleanEstimate Pro, the fleet module generates this proposal automatically. You select the vehicle types, enter the fleet size, choose the frequency, and the system builds the proposal with your branding, your rates, and monthly/annual pricing options. The margin badge confirms you are profitable before you send it.

Your first fleet contract will probably come from driving around and looking at trucks. Seriously. Drive through industrial parks, distribution centers, and commercial districts. Look for lots with 10 or more branded vehicles. If a company has enough trucks to fill a parking lot, they need them washed. Note the company name, look up the fleet manager or operations manager on LinkedIn, and reach out with a simple pitch: "I noticed your fleet of [vehicle type] at [location]. We specialize in fleet washing and I would like to send you a quote. How many vehicles do you have and how often are they currently being washed?" Most fleet managers will tell you one of three things: they are not currently washing regularly (opportunity), they have a current provider but are not happy (opportunity), or they have a provider and are satisfied (move on). The close rate on fleet contracts is lower than residential — expect 15–25% — but the lifetime value is dramatically higher. One fleet contract at $40,000/year that lasts 3–5 years is $120,000–200,000 in revenue from a single sales conversation. Other lead sources: local trucking companies, delivery services (FedEx Ground contractors, Amazon DSPs), HVAC companies with service van fleets, plumbing companies, pest control companies, auto dealerships (dealer lots need regular washing), and municipalities (city vehicle fleets). Start with one contract, deliver consistently, and ask for referrals. Fleet managers talk to each other. One good contract leads to the next.
