Ask ten mobile detailers about their detailing service area radius and you will get ten different numbers, most of them picked by feel. Twenty miles sounds reasonable. Thirty sounds ambitious. "Anywhere within an hour" sounds generous right up until you are sitting in traffic at 4 p.m. with a half empty tank and no second job on the board. The right answer is not a feeling. It is arithmetic you can run in twenty minutes using your own invoices, and it almost always lands tighter than you expect.
Your radius is a pricing decision, not a map decision
A fixed shop sells bay time. You sell daylight. When a car rolls into a bay, the shop's overhead is paid whether the customer drove five minutes or fifty. When you drive fifty minutes, you burn production hours you can never bill, at the exact hourly rate you charge for polishing paint.
So stop asking how far you are willing to drive. Ask what a job has to be worth before the drive makes sense. Framed that way, the radius stops being a circle on a map and becomes a set of minimum tickets. Close jobs can be an express interior. Far jobs cannot.
Run the drive time math on your own numbers
Here is the calculation with example figures. Say your bread and butter package is a full interior and exterior detail at $220, and it takes three hours on site once you count setup, teardown, and the walkaround. Three of those fills a working day, so your on site time is worth roughly $73 an hour.
Now add travel. With a tight radius and jobs clustered fifteen minutes apart, you fit three tickets and go home at $660. With a loose radius and forty five minutes between stops, you fit two and go home at $440. Same fuel spend on your part, same labor, same wear on the trailer, and $220 less in the till. That third job is not extra income. It is the day's profit.
That gives you a clean rule for the edges of your map. A forty five minute one way drive costs ninety minutes of production, about $110 at that example rate, before fuel. So a far edge job needs to be closer to $330 to net what a $220 job nets ten minutes from home. That is not greed, it is break even. It also explains why "we travel anywhere" is such a popular promise and such a bad business: it prices the worst jobs like the best ones.
The costs that never make it into the estimate
Drive time is the big one, but it is not the only cost that scales with distance. Water refills eat twenty minutes and force a route detour. A full tank means worse fuel economy on every mile. Generator hours are maintenance hours. Add tolls, gated communities that make you wait for a call in, and street parking where you cannot get the rig within a hose length of the car. Then add the site conditions you cannot verify from far away: no spigot, no outlet, no shade in July, an HOA that will not allow visible runoff. Each of those is survivable ten minutes from home and expensive forty minutes out, because you cannot go back for the missing part.
Want a site that books detailing jobs while you work?
Arbor builds and runs the website for detailers: your packages and prices, built to rank locally, with an AI chat that answers visitors and captures the lead day and night. See what a real detailer's live site looks like.
Websites for auto detailersBuild your detailing service area radius in tiers
One circle is too blunt. Three zones with different minimum tickets let you say yes to the right work at the right price instead of saying yes to everything and hoping it averages out. Here is the shape of it, with example numbers to replace with your own.
| Zone | One way drive | What you accept | Minimum ticket |
|---|---|---|---|
| Core | Up to 20 minutes | Any package, including express and single add ons | Standard pricing, no travel charge |
| Extended | 20 to 40 minutes | Full details and up, add ons only when attached | Roughly 1.5 times your core minimum |
| Reach | 40 to 60 minutes | Correction, coatings, multi vehicle stops | Premium ticket plus a deposit |
Bundle the travel into the package price for each zone rather than tacking on a mileage line item. A separate travel fee reads like a penalty and invites negotiation. A higher minimum reads like a policy, and policies do not get argued with nearly as often. If a customer in the reach zone wants your $99 express interior, the honest answer is that express is a core area package, and here is what you can do at their address instead. Most people accept that immediately.
The jobs worth driving past your line for
The radius is a default, not a fence. These are the situations where breaking it is the correct call:
- Multi vehicle stops. Two or three cars at one address turns a bad drive into a great day. The travel cost is fixed and you amortize it across every ticket.
- Coatings and paint correction. A multi day, high ticket job where the drive is a small fraction of total revenue, and where you may be working in the client's garage anyway.
- Fleet and small commercial accounts. Recurring routes justify a longer haul because you can build the rest of the day around a known anchor.
- Neighbor clusters. One good job on a street often produces two more. Take the far job when you can book a same day second stop within walking distance, and ask for it directly.
- Loyal repeat clients who moved. Keeping a client who books twice a year and refers people is worth an inefficient afternoon, as long as you know that is the choice you are making.
What they share is that the drive gets divided by more revenue. If a far request fits none of those patterns, it is a core zone job at the wrong address.
Let the radius breathe with the season
Your map should not be the same in April as it is in November. During the pre summer rush, when pollen and road grime have everyone calling at once, you have more demand than daylight. That is the moment to shrink the extended zone, raise minimums, and fill the day with tight clusters. In the slow stretch, whether that is deep winter in a salt state or the rainy months elsewhere, an empty day is worse than an inefficient one, so widen the reach zone and take the drives you turned down in spring.
Season changes where the center of your circle sits, not just its size. Snowbird and vacation markets shift population by the month. Coatings and correction also hold up better in the off season because they often happen under cover, which is one more reason to reserve your longest drives for that work.
Publish the radius so customers and AI answers get it right
A quiet drain on most mobile operations is quoting people who were never bookable. The fix is putting the zones on your website in plain language: the towns and neighborhoods you cover, the ZIP codes, the honest outer edge, and what changes past it. Name real places, because Google and AI assistants like ChatGPT and Perplexity read the words on the page, not the map in your head. When someone asks an assistant who details cars in a specific suburb, the site that names that suburb is the one that gets recommended. More on structuring those pages is in our notes on websites for mobile detailers.
If keeping that page current is the part that never actually happens, that is the work Arbor takes off your plate. We build and run the site, and when a zone changes you tell Sage in plain chat to add the town or bump the minimum, then click publish. You can also grade the site you have now with the free checker at arbor.zone/seo-score, which scores it for Google and AI search in a minute.
Either way, start with the arithmetic before you touch the website. Pull your last thirty invoices, mark the drive distance and the total on each one, and work out your real revenue per hour including travel. Your true break even distance will show up fast, and it will probably sit closer to home than the radius you have been advertising. Write the three zones down, set a minimum ticket for each, and hold to them for a month. Then compare that month's take against the last one.
