How to choose a mobile car detailer

A practical checklist for picking a mobile car detailer that does the work properly — what to verify, what to avoid, what to ask.

Five hard criteria {#criteria}

The non-negotiables, in priority order:

1. Verified Google Business Profile with photos, hours, and active phone response. If the GBP doesn’t exist or is empty, the operator isn’t running a real business.
2. At least 30 reviews averaging 4.3+ — Volume matters as much as rating. A 5.0 with 8 reviews is fragile. A 4.6 with 200 is reliable.
3. A visible portfolio — Either on the GBP, an Instagram account, or a website. Before-and-after photos of actual work, not stock imagery.
4. Liability insurance — A reputable mobile detailer carries general liability ($1M minimum) plus garage-keeper’s insurance for any work involving paint correction or coating. Ask for proof.
5. Transparent pricing — A quote that itemizes services, add-ons, and any travel or disposal fees. If the only number you can get is “starts at $99,” that’s not enough information.

Our network filters for all five. If you’re hiring outside the concierge, walk through this list before booking.

Six questions to ask {#questions}

The questions a smart consumer asks before booking. These separate the operators who know what they’re doing from the ones who don’t:

1. “What’s your process for [specific issue]?” — Pet hair, water spots, swirls, oxidation. The detailer should describe a specific procedure, not “we’ll take care of it.”
2. “What products and brands do you use?” — Reputable operators are happy to name their chemistry. If they dodge, that’s a signal.
3. “What happens if I’m not satisfied?” — A standing policy, even a verbal one, beats no policy. The good operators come back to fix.
4. “Where do you do paint correction or ceramic coating?” — These should happen in a covered space. A driveway answer in February means they’re cutting corners.
5. “Are you certified for any specific coatings or chemistry?” — IGL, Gtechniq, Ceramic Pro, CQuartz Finest — these certifications come with training and warranty backstops.
6. “How long have you been doing this?” — Two years minimum for paint correction or coating work. The chemistry is unforgiving and apprenticeship is real.

Red flags {#red-flags}

These should make you walk away from a quote regardless of price:

• Door-to-door solicitation — Mobile detailers don’t cold-knock. Anyone offering you a same-day driveway detail off the street is either a scam or a low-quality operator.
• Pre-payment in full before any work — A deposit (20–30%) is normal for coating or correction work. The full amount upfront is a red flag.
• “We can definitely do that today” for ceramic coating or paint correction — These require prep and scheduling. Anyone promising immediate ceramic in any weather is cutting corners.
• No physical address or business registration — A business license matters. The concierge requires one for the network.
• Reviews that all sound the same — Five reviews in the same week, same writing style. That’s a paid-review operation; the real reviews are buried.

How to read reviews {#reviews}

Reviews are noisy. Three filters cut through:

• Ignore the 5-star and 1-star outliers. Read the 3- and 4-star reviews. They contain the truthful caveats — “good work but took longer than promised,” “great on interior but missed a few spots on the headliner.”
• Look for specific work descriptions — Reviews that mention “ceramic coating on my 2023 Highlander” or “extracted pet hair from a Camry” are signal. Reviews that say “amazing service” without specifics are noise.
• Check the review date distribution — A flat, evenly-spread review history is healthy. A cluster of 20 reviews in one week then nothing is suspicious.

The concierge already does this filtering as part of the quality score, so detailers we route to have been through this lens already.

Price vs quality {#price}

The cheapest detailer in a metro is almost never the best deal. Here’s the math:

A real interior detail involves $30–$50 of chemistry, 2–3 hours of labor, and equipment depreciation. An operator quoting $80 for a “full interior detail” is either using a single-bucket water swap, skipping extraction, or doing 90 minutes of work and calling it a detail. You’ll get a clean-looking car for a week and the carpet will still smell like wet dog by Friday.

That said, the most expensive detailer isn’t automatically the best. The premium operators often charge for amenities (Pearl District luxury van, branded chemistry) that don’t necessarily produce a better outcome on a daily-driver Civic.

The sweet spot in most metros is the mid-priced operator (within 10% of the median quote) with 50+ reviews at 4.7+ stars. That’s who the concierge defaults to recommending.
