Hiring an agency as a mobile detailer: six questions

Mid-May is the busiest stretch of a detailer’s year in most of the country. Tree pollen has given way to grass pollen, people are getting cars ready to sell or to drive across three states in July, and the schedule is full enough that the owner finally believes marketing could work. It is also when agencies with a generic home services package come calling.

A mobile detailer is not a generic local business, and the difference shows up in the first conversation. Here are six questions we would want any detailer to ask an agency, including us, before signing anything.

Start with the address

What will you do with my address?

This one sorts agencies quickly. Google’s guidelines say a business without permanent on-site signage, and that does not serve customers at its address, is not eligible as a storefront and should be listed as a service-area business with the address hidden. If you work out of a home garage and go to the customer’s driveway, that is you.

An agency that suggests showing the home address “because it ranks better” is offering to put your profile at risk. The honest answer is a service-area profile, and a plan to compete without the pin.

How will I compete with shops that show an address?

Ask this directly, because the gap is real. Whitespark’s 2026 Local Search Ranking Factors survey has local search experts ranking a physical address in the city of the search 4th among map pack factors, and an address showing on the profile 7th. A mobile detailer gets neither.

A good answer covers the things you do control: the primary category (ranked 1st in the same survey), review volume and recency, photos of real cars, and paid placements. That last one includes Local Services Ads, where Car Detailing Service is a category of its own. Ask whether the agency knows that those ads run without a badge, because Google says the Google Verified badge is currently unavailable for auto categories. If they promise you a verification badge, they have not looked.

Which towns go on my profile?

Google allows up to 20 service areas, set by city or postal code, never as a radius, and asks that they stay within about two hours of driving from the business base. Listing every suburb in the metro does not help a single van. It brings requests from places you will not drive to on a Saturday. The right agency asks where you actually go, then uses ads to test the edges before adding a town.

Ask how they will get you chosen

How will you get reviews without breaking the rules?

Reviews do more of the selling for a mobile detailer than for a shop, since there is no storefront to look at. In BrightLocal’s 2026 survey of consumers, nearly half (47%) said they pass over any business with under 20 reviews, and 74% said only reviews from the past three months matter to them.

The method matters as much as the volume. Google’s review policy bans incentives and asking only the customers you expect to be happy. The FTC’s rule on consumer reviews and testimonials has been in effect since October 21, 2024, with civil penalties for knowing violations. A free air freshener for a five-star review breaks both. Ask the agency to show you the request message they would send, and when.

While you are on the subject of proof, ask how they would use credentials. If you hold International Detailing Association certification, it belongs on the profile and site: ten written exams earn IDA Certified Detailer, a hands-on assessment earns Skills Validated, and keeping it takes 8 hours of continuing education every two years. Buyers rarely see a checkable credential on a detailing site, which is why it is worth showing.

Ask what they will write for you

What will you say about my coatings and my water?

Two claims get detailers in trouble, and an agency writing your copy will be tempted by both.

The first is durability. “Five-year ceramic coating” and “permanent protection” read well on a banner. Ask the agency where the number comes from. The answer should be the product maker’s written warranty and the upkeep it requires, printed on the package page. If the warranty does not say it, the page should not either.

The second is the word “eco”. San Diego County allows only rainwater in its streets and storm drains, and says wash water must be emptied to the sewer. Streets to Creeks, a regional stormwater program, notes on its page for mobile detailers that soap labeled nontoxic or biodegradable is still a prohibited discharge, and that a wastewater discharge permit may be required. If your van captures and reclaims water, the copy should say exactly that. An agency that writes “eco-friendly biodegradable wash” without asking where the water goes is writing a claim you will have to defend.

What ninety days and a good report should look like

Price comes up early in every pitch. Thumbtack’s national guide, published last month, puts the average mobile detail at $144 to $254, with basic services as low as $95 and high-end details at $390 or more. That range is what your buyers have in their heads, and it tells you why lead cost has to be judged against the job, not in isolation.

The first ninety days for a mobile detailer should look roughly like this:

• Weeks 1 to 2. Profile type corrected, service areas set to real towns, categories and services filled in, Local Services Ads application under Car Detailing Service.
• Weeks 3 to 6. A review request after every car, a photo library of your own before-and-after work, a page for each package, claims rewritten to match the warranty and your water method.
• Weeks 7 to 12. Search ads on coating, correction and film terms, reminders to past customers, cost per booked job compared across channels.

A good monthly report shows booked cars by source and what each cost, not clicks and impressions. It separates a basic interior job from a coating job, because they are different businesses inside one van. It tells you how many calls and texts went unanswered while you were mid-job. If a report cannot tell you which channel paid for last month’s coatings, it is not a report.

What we are telling clients

1. Ask every agency what they would do with your address, and walk away from any that suggest showing a home garage as a storefront.
2. Ask to see the review request message and its timing before you sign.
3. Make the agency name the source of any durability claim it wants to print.
4. Find your local stormwater program and make sure the wash copy matches your method.
5. Agree on one definition of a lead, a booked car, before the first invoice.
6. Ask for a report sample that shows cost per booked job by channel.
