How to check a detailer's work before you book

A detailer who knows their craft will restore your car's paint, trim and interior to a standard you can see and feel. But booking someone without checking their actual output first is a gamble. Before you commit, you need proof that they can deliver what they promise—not just a portfolio on Instagram, but real evidence that their work holds up.

Check their registration and insurance

Start with the basics. Ask the detailer for their registration number with the relevant professional body or tax compliance authority. Request proof of public liability insurance; this protects you if something goes wrong during the work. A legitimate detailer will have these documents ready to share without hesitation. If they're vague or say "it's not necessary," walk away. You want someone operating above board, not cutting corners on the legal side.

Look at finished cars in person

Photos can be flattering. Lighting, angles and filters hide flaws. Instead, ask the detailer if you can see a car they've recently detailed—ideally one that's been on the road for at least a month or two, not fresh from the shop that morning. A properly protected detail should still look sharp weeks later. Run your hand over the paintwork. Does it feel smooth and glossy, or dull and rough? Open and close the doors; do the hinges and jambs look clean? Sit in the car. Are the carpets thoroughly dry, or do they smell musty? These tactile checks tell you far more than a photograph.

Speak directly to past clients

Ask the detailer for the contact numbers of at least three people whose cars they've detailed in the last six months. When you call, ask specific questions: Did the work arrive on time? How long did the finish last before it started to dull or mark? Have they used the detailer again, or recommended them to others? Pay attention to whether the clients sound genuinely satisfied or guarded. Ask whether the detailer addressed any problems if they arose—responsiveness and integrity matter as much as technical skill. If the detailer refuses to provide references or the numbers don't work, that's a red flag.

Request a quote based on an inspection

A detailer should visit your car or ask you detailed questions about its condition before quoting. If they offer a blanket price without seeing the vehicle, they're either guessing or planning to cut corners when they discover what they're actually working with. A thorough inspection shows professionalism and helps you understand what the job will entail. During this conversation, ask them to walk you through their process: what products they use, how long each stage takes, and what protection they'll apply after cleaning. Listen for specifics. Vague answers suggest they may not have a structured method.

Clarify what "guarantee" means in writing

Many detailers mention warranties or guarantees, but these vary wildly. Before booking, ask them to explain in writing what they guarantee and for how long. Does a ceramic coating guarantee mean the protection won't wear off, or that they'll reapply it free if it does? What happens if you spot a swirl mark three weeks after the detail? A reputable detailer will be clear about the scope and limits of their work, and they'll put it in a simple agreement so there's no misunderstanding later.

When you're confident in your choice, you can book with assurance.

Start there, do your own checks, and you'll end up with someone who treats your car with the care it deserves.
