Why Pricing Is a Skill
Most new pressure washing operators underprice their work. They look at what competitors are charging, match or beat it, and find that after fuel, chemicals, equipment wear, insurance, and their own time, they are left with very little. Some find they are effectively working for less than minimum wage while appearing to be busy.
Pricing correctly is not about charging more than the market will bear. It is about understanding your actual costs, knowing what you need to earn to make the business viable, and presenting your price with confidence. An operator who knows their numbers and can explain their value will win work at a sustainable price. An operator who guesses and discounts will stay busy but not profitable.
Understanding Your Costs
Before you can price a job correctly, you need to know what it costs you to operate. This is not optional — it is the foundation of every price you produce.
Fixed costs
Fixed costs are the costs you incur regardless of how many jobs you do — they exist whether you are working or not. They include van insurance, public liability insurance, equipment finance or replacement fund, phone contract, website or booking system costs, and any professional memberships or subscriptions. Add up your fixed costs for a year, then divide by the number of working days you plan to work. This gives you your fixed cost per working day — a floor below which you cannot price without making a loss before you have even started the van.
Variable costs
Variable costs change with the volume of work you do. They include fuel, chemicals, water (if you are purchasing a bowser supply), disposable PPE, and equipment consumables such as nozzles and hose fittings. Calculate your average variable cost per job based on your most common job type — driveway, patio, render clean — and build this into your pricing.
Your time
Your time is a cost. Decide what you want to earn per hour — not what you hope to earn, but the minimum hourly rate that makes the business worthwhile for you. Add travel time, setup time, job time, and pack-down time. An hour's drive each way to a two-hour job is actually a four-hour commitment. Price it as four hours, not two.
Calculate your minimum viable day rate: Add your fixed cost per day to your minimum acceptable earnings per day. That total is the minimum revenue you need to generate on a working day to cover your costs and pay yourself. Every job you price should contribute to hitting that number. A job priced below your cost floor is a job that costs you money to do.
Pricing Methods
Pricing by area
Pricing by square metre is the most transparent and scalable method for flat surface cleaning — driveways, patios, car parks, and commercial yards. Measure the area, apply your rate per square metre, and adjust for contamination level, surface type, and access. Area-based pricing scales predictably and is easy to explain to clients. The risk is that it does not account for surfaces that take significantly longer to clean than your rate assumes — heavily contaminated block paving versus a lightly soiled concrete drive may both be priced at the same per-metre rate but take very different amounts of time.
Pricing by time
Pricing by time — a day rate or half-day rate — is more appropriate for complex jobs where the scope is hard to define in advance, or for ongoing commercial contracts where the volume of work varies. The advantage is that your revenue is directly tied to your time on site. The disadvantage is that clients sometimes resist time-based pricing because they cannot predict the total cost in advance. Provide a time estimate with a range rather than a fixed figure, and be clear about what affects the time required.
Pricing by job
A fixed job price — a single figure for a defined scope of work — is what most domestic clients prefer. It gives them certainty. For you, it requires that you accurately estimate the time and materials before you commit to the price. Build in a contingency for the unexpected — a surface that is more contaminated than it appeared, or access that proves more difficult than anticipated. A fixed price with a clear scope of works protects both parties.
Producing a Professional Written Quote
A verbal quote is not a quote — it is a conversation. A written quote is what protects you when a client disputes the price, adds to the scope without expecting to pay more, or claims you agreed to something you did not. Always quote in writing, even for small domestic jobs.
A professional written quote should include your business name, address, and contact details; the client's name and address; the date of the quote and a validity period; a clear description of the works included; a clear statement of what is excluded; the total price and whether it includes VAT; your payment terms; and a brief note on your insurance cover. This does not need to be elaborate — a clean, simple one-page document is more professional than a long formal contract for most domestic work.
| Quote Element | Why It Matters |
|---|---|
| Scope of works — included | Sets out exactly what you will clean. Prevents the client adding the fence, the garage roof, and the neighbour's drive for the same price. |
| Scope of works — excluded | Equally important. If you are not cleaning the conservatory roof or the side passage, say so explicitly. |
| Price and VAT status | If you are VAT registered, state the ex-VAT price and VAT separately. If not, state that the price is not subject to VAT. |
| Payment terms | When do you expect to be paid? On completion? Within 7 days? By bank transfer or cash? State this upfront, not after the job. |
| Quote validity period | Prices for fuel, chemicals, and labour can change. A quote valid for 30 days protects you from being held to a price given months ago. |
| Insurance details | Public liability insurance level and provider. Gives the client confidence and is expected by commercial clients as standard. |
Handling Scope Changes on Site
A client who asks you to clean something additional while you are on site is a common situation. How you handle it determines whether it is good news or a problem.
If a client asks you to add work that was not in the original quote, treat it as a new instruction. Stop, give them a price for the additional work, get agreement before you proceed, and note it in writing — even a text message confirmation is better than nothing. Do not complete additional work and then add it to the invoice without prior agreement — clients who have not mentally committed to paying for extra work will dispute it, even when they asked for it.
Following Up Quotes
Most pressure washing enquiries do not convert immediately. The client gets three quotes, thinks about it, talks to their partner, and then decides — sometimes days or weeks later. A quote that you send and never follow up has a significantly lower conversion rate than one you follow up once, politely, after a few days.
A simple follow-up message — "Just checking you received my quote and whether you have any questions" — is not pushy. It is professional. It also gives the client an easy opportunity to raise a concern that might be preventing them from booking, which you can then address.
Job Scheduling and Time Management
Efficient scheduling is the difference between a day that generates good revenue and a day spent driving between jobs that each take longer than expected. Build your schedule around travel time, not just job time. Group jobs by geography where possible — two jobs in the same postcode district on the same day is more efficient than two jobs on opposite sides of your area.
Allow buffer time between jobs. Chemical dwell time, unexpected access issues, a client who wants to talk — these are normal parts of the job. A schedule with no slack will routinely run late, which creates stress and generates complaints from clients who were expecting you at a specific time.
- Confirm bookings the day before with a brief message — it reduces no-shows and last-minute cancellations significantly.
- Give clients a time window rather than an exact arrival time — "between 9am and 10am" manages expectations more reliably than "9am sharp".
- Keep a simple job log — date, client, address, job description, price, payment status. You will need this for your tax return and it takes thirty seconds per job to maintain.
- Note any pre-existing damage at the start of every job with a photograph. This protects you from damage claims and costs nothing.
