How to choose a mobile detailer in the Portland metro
The word mobile covers two completely different businesses. Five questions tell you which one is coming to your house.

Start with water and power
Ask one question first: do you bring your own water and power? The answer sorts the market instantly.
A self-contained rig carries a tank, filtration, a pressure system, a generator and extraction equipment. It can work at an office lot, a condo garage or a legal street spot in Sellwood. An operator who needs your outdoor spigot and an extension cord through your window can only work at a house, in reasonable weather, and cannot take on a coating job at all.
Neither is dishonest. They are just different services at different prices, and you should know which you are buying.
Ask what happens before the polisher comes out
If someone quotes paint correction without mentioning decontamination or paint thickness, that is worth pausing on.
Clear coat is finite. Polishing removes some of it, permanently. A detailer who measures thickness before cutting is protecting your car from a mistake that no one can undo. A detailer who does not measure is guessing, and on a panel that has been corrected twice before, guessing has consequences.
The same goes for a test spot. You should see the result on your own paint, under the same light, before the rest of the car is touched.
Look at what they photograph
A detailer's own photos tell you what they care about. Wide shots of clean cars in golden light tell you very little, because a rinsed car looks clean from ten feet away.
What tells you something is close work: a wheel barrel, a door jamb, a seat rail, a panel under a single hard light source. Those are the places that separate a detail from a wash, and an operator who is proud of them will show them.
Ask what they will not do
This is the most revealing question in the trade. Everyone will tell you what is included. Fewer will tell you what they refuse.
A good answer sounds like this: we will not coat uncorrected paint without telling you, we will not fill scratches with glaze and call it correction, and we will not mask an odor whose source we have not found. Those are all shortcuts that look excellent for about six weeks.
Red flags worth walking away from
None of these are automatically disqualifying. All of them deserve a follow-up question.
- A firm price quoted with no questions about size or condition
- A full detail advertised at a wash price
- Any promise to remove every scratch
- No mention of where the car needs to sit for a coating cure
- Reluctance to say what product is going on your paint
