The reality check
Mobile detailing is one of the few trades where a careful operator can be cash-positive in the first month. There is no licence to wash a car, the customer supplies the location, and the work is sold on a visible before-and-after that markets itself. The constraint is throughput: you are selling hours in a driveway, and the ceiling is how many vehicles you can finish well in a day.
Realistic startup cost is $2,500 to $15,000. The essentials: a dual-action polisher at $150 to $400, a hot-water or rinseless wash setup, an extractor at $400 to $1,200, a wet/dry vac, a steamer at $200 to $700, a pressure washer at $300 to $900, a 65 to 100-gallon water tank and 12v pump at $300 to $800, chemicals and pads at $400 to $900, a generator at $500 to $1,200, and towels, brushes and lighting at $400. Insurance runs $600 to $1,800 a year. You do not need a wrapped van on day one — a reliable SUV or pickup with a tidy setup and a booking link converts perfectly well.
Pricing in most US metros: a maintenance wash at $60 to $120, a full interior and exterior detail at $180 to $350, single-stage paint correction at $350 to $700, and a professional ceramic coating at $800 to $2,500 depending on prep and warranty. Two full details a day at $250 is $500 gross; a coating job is a day's revenue in one booking, which is why most operators move up-market within a year. Chemicals and consumables run 8 to 15 per cent of revenue, so a solo detailer working five days grosses $70,000 to $130,000 and keeps a genuinely good share of it.
Water rules, permits and insurance
The wash-water rule that surprises people
Detailing is lightly licensed but wash water is not. Under the Clean Water Act, commercial wash water is generally not allowed to enter a storm drain, and many municipalities enforce this directly against mobile operators — the runoff carries detergent, brake dust and oils that storm systems discharge untreated. The practical answers are the ones the industry already uses: rinseless and waterless washing for most maintenance work, a reclaim mat for pressure washing, or washing on gravel or grass where the water infiltrates rather than running to the curb. Check your city's stormwater ordinance and the EPA stormwater program before you plan around a pressure washer, and expect apartment complexes and commercial lots to ask about it.
Business setup and permits
Register the business, get an EIN, and add a local business licence. Because you work at the customer's address, two extra permissions matter: many cities require a mobile or itinerant vendor permit, and apartment complexes, HOAs and office parks usually require permission from property management plus a certificate of insurance naming them. Sales tax treatment of detailing services varies by state — some tax the service, some tax only the products — so confirm with your state revenue department before you set prices.
Insurance
You need garage keepers or care-custody-and-control coverage, not just general liability: general liability does not cover damage to the customer's vehicle while it is in your care, which is the claim you are actually exposed to. Add commercial auto for your own vehicle and equipment coverage for the tools in it. Budget $600 to $1,800 a year for the package as a solo operator, and take photos of every vehicle before you start — the booking form's condition questions plus a walkaround photo set is what settles a scratch dispute.
Packages, pricing and keeping the calendar full
Sell three named packages, not an hourly rate. A maintenance wash, a full detail and a correction or coating tier let customers self-select and let you predict duration. Then price by vehicle size — a three-row SUV is 40 to 60 per cent more interior than a sedan — and charge explicitly for the conditions that eat time: pet hair, smoke odour, sand, child seats and spilled food. Detailers who absorb those quietly lose an hour a job and blame the price.
Protect the schedule with arrival windows rather than exact times, a 24-hour cancellation policy stated at booking, and a deposit on first-time customers. No-shows and 'we moved the car' are the largest hidden cost in mobile work. Confirm each job with the hours you will need on site, the parking spot required, and whether you need a tap and an outlet — because that is what actually decides whether the job can happen.
Growth comes from repeat work and referral density. Put every customer on a maintenance interval — monthly or quarterly — at a lower price than a one-off, because a filled Tuesday at $90 beats an empty Tuesday at $250. Ask for a Google review while the car is still wet and the customer is standing next to it; local search for detailing is won on review count and recency. Fleet work, dealerships and realtor gift details fill weekday mornings, which is when consumer demand is weakest.

Frequently asked questions
- Do I need a special licence to detail cars in the USA?
- No state licences detailing itself. You need a local business licence, often a mobile vendor permit, and permission from any property where you work. The regulated part is wash-water discharge, not the service.
- Can I legally wash cars in a customer's driveway?
- Usually yes, provided your wash water does not run into a storm drain. Rinseless washing, a reclaim mat, or washing on a permeable surface are the standard compliant approaches; check your city's stormwater ordinance.
- What insurance do I actually need?
- General liability plus garage keepers or care-custody-and-control coverage, because damage to the customer's vehicle while you are working on it is excluded from a plain liability policy. Add commercial auto and equipment cover.
- How much should a full detail cost?
- In most US metros a full interior and exterior detail sits at $180 to $350 depending on vehicle size and condition, with paint correction from $350 and ceramic coatings from around $800.
- How do I stop no-shows?
- Take a deposit on first-time bookings, state a 24-hour cancellation policy at the point of booking, and send a reminder the day before that repeats the parking, water and power requirements.
