Most detailers buy insurance the same way. Somebody says "you need to be insured," you get a general liability policy, you put "fully insured" on your flyer, and you move on.
Then one day the buffer sits too long on a soft hood and burns through the clear coat. You call your insurance company, feeling covered.
And you find out the policy doesn't cover the customer's car.
This post is a plain-English walk through what each type of coverage actually does for a mobile detailer, so you can ask the right questions when you get quotes. One thing up front: this isn't legal or insurance advice. Requirements and policies vary by state and by insurer. Use this to understand what you're buying, then talk to a licensed agent.
General liability: the baseline
General liability is the policy most people mean when they say "I'm insured." It's built for things like:
- A customer trips over your hose and gets hurt.
- You knock over a planter or scratch a garage door while working at someone's house.
- Someone says your work caused damage to their property.
It's the foundation, and a lot of commercial customers, dealerships and apartment complexes will ask to see it before you work on their property.
But here's the catch most detailers miss. General liability policies commonly exclude property that's in your "care, custody or control." When you're detailing a car, that car is in your care. So the one thing you're most likely to damage, the vehicle, is often the thing your general liability doesn't cover.
Read your policy for that exclusion, or ask your agent directly: "If I damage the customer's car while I'm working on it, am I covered?"
Garage keepers: the one that covers the car
This is the coverage built for exactly that gap. Garage keepers (sometimes sold as "care, custody and control" coverage) is designed to cover damage to customer vehicles while they're in your hands.
For a detailer, that's the whole job. Burned paint, a cracked windshield from a dropped tool, a stained headliner from the wrong chemical, a door dinged while you're working. Those are the claims that actually happen in detailing, and this is the policy aimed at them.
When you get quotes, ask how the policy pays out and whether it covers damage you caused, or only certain events like fire or theft. Policies differ, so get it in writing.
Commercial auto: for the van or truck
If you drive to customers, your vehicle is a work vehicle. Personal auto policies often exclude business use. If you get into an accident on the way to a job, a personal policy might not pay.
Tell your insurance company you use the vehicle for business. A commercial auto policy, or the right business-use endorsement, is designed for that. It's also worth asking whether your water tank, generator and equipment change anything.
Tools and equipment coverage
Your polishers, extractor, pressure washer, generator and chemicals are expensive, and they ride around in a van that's parked on the street a lot of the day.
Coverage for tools and equipment that move from place to place is often called "inland marine." The name is confusing, but the idea is simple: it covers your gear when it's out of the shop. Check whether it covers theft from a locked vehicle, because that's the one detailers worry about most.
Workers' comp, once you hire
The day you hire your first employee, look into workers' compensation. Rules on when it's required depend on your state, so ask your agent what applies where you work. Don't assume you're exempt because it's "just one guy on weekends."
What won't cover any of this
Two policies people lean on that usually won't help:
- Homeowners or renters insurance. These are built for your home and personal stuff, not a business.
- Personal auto insurance. As above, business use is often excluded.
If your business runs out of your house and your personal car, that's exactly the setup where coverage gaps hide.
How to shop for it
- Get quotes from more than one agent, ideally one who works with auto service businesses.
- Ask the car question directly for every policy: "Am I covered if I damage a customer's car while working on it?"
- Ask what the limits and deductibles are, and whether they fit the cars you work on. A daily driver and a six-figure car are different risks.
- Build insurance into your startup budget and your prices. It's a real cost of doing business. We walk through the rest of that budget in mobile car wash business startup costs.
- Keep before-and-after photos of every vehicle. If something goes wrong, photos of the car's condition when you arrived make every conversation easier.
The short version
- General liability is the baseline, but it often excludes the customer's car.
- Garage keepers is the coverage aimed at damage to the vehicles you work on.
- Your van needs business-use auto coverage.
- Your gear may need its own coverage.
- Workers' comp comes in when you hire.
- None of this is covered by homeowners or personal auto.
Being "fully insured" should mean you can tell a customer, honestly, that their car is covered if something goes wrong. That's worth a phone call to your agent this week.
