Ask three St. Louis shops what a full detail costs and you can easily hear $200, $450, and $700. None of them is necessarily wrong. Detailing is sold by the job but priced by the hour, and what one shop calls a “full detail” can be a three-hour cleanup or a nine-hour rebuild of a neglected interior. Here is how the math actually works, what the ranges look like around St. Louis, and how to tell whether two quotes are even describing the same work.

What You Are Actually Paying For

Soap and towels are a rounding error. Detailing pricing is almost entirely labor plus bay time, and a shop that is doing it properly is tying up a lift or a bay and a trained tech for most of a day. Effective shop rates for detail work in the St. Louis market generally run somewhere in the $60–$95 per hour range once you back out the consumables, so the real question behind any quote is simple: how many hours does this car need?

Three things drive that number more than anything else.

• Condition. A two-year-old sedan that gets washed regularly might need four hours. The same car after three kids, two dogs, and a spilled gallon of milk can need nine. Condition is the single biggest swing factor, and it is why no honest shop can quote a firm interior price over the phone.
• Size. An Escalade or a crew-cab Sierra has roughly double the glass, carpet, and painted surface of a Civic. Most shops price in size tiers — coupe/sedan, midsize SUV, full-size SUV and truck — and the spread between the smallest and largest tier is usually 30–50 percent.
• Paint goals. Cleaning paint and correcting paint are different jobs. A wash, decontamination, and sealant is a few hours. Removing swirl marks with a machine polisher is a full day or more. Most of the sticker shock people run into comes from crossing that line without realizing it.

Detailing Prices Around St. Louis

The table below reflects the ranges we see across the St. Louis market for reputable shops doing the work by hand. Treat them as brackets, not quotes — your vehicle’s size and condition decide where inside the bracket you land, and the only way to get a real number is to have someone look at the car.

Exact pricing always comes from a free quote — a well-kept lease turn-in and a work truck with a decade of jobsite dust are not the same job even if both are “full details.”

Interior vs. Exterior: Where the Hours Go

Interior work is the least predictable

Interiors are where estimates go sideways. Pet hair woven into carpet fiber has to be pulled out with a rubber brush and a lot of patience, and it is not unusual for hair removal alone to add two hours. Ground-in salt stains from a Missouri winter need a hot-water extractor and multiple passes. Sun-baked dash plastics, sticky soft-touch trim, spilled coffee that soaked into the seat foam — each of those is a separate mini-project.

Leather is its own line item. Cleaning it properly means a pH-appropriate cleaner, a soft brush on the perforations, and a conditioner that gets time to absorb. Rushed leather work looks fine for a week and then goes blotchy.

Exterior work is more predictable but more skill-dependent

The exterior side follows a repeatable sequence: wheels and tires first, then a decontamination wash, then a clay bar or clay mitt to pull embedded rail dust and overspray out of the clear coat, then paint work, then a sealant or coating. The hours are fairly consistent for a given size of vehicle. What varies is the quality of the paint step — and that is where experience shows.

Add-Ons and What They Cost

Most shops quote a base package and then price extras individually. These are the ones worth knowing about.

The two that pay for themselves most often are odor treatment and headlight restoration, because both fix something you notice every single drive. Ceramic coating is a different category of spend entirely — it is protection, not cleaning, and it only makes sense on paint that has already been corrected. We broke down that decision in is ceramic coating worth it in St. Louis.

Paint Correction Is the Big Variable

If a quote surprises you, paint correction is usually the reason. Correction means machine-polishing the clear coat to physically level out swirl marks, wash scratches, and etching. It is measured in hours per panel, not hours per car, and a dark-colored vehicle shows every defect you did not remove — which means dark cars take longer.

A one-step polish knocks out most light swirling and gets a car looking dramatically better for a reasonable number of hours. A multi-step correction chases the deeper defects and can easily run two to four days of bench time. Neither is a maintenance service; you do it once, and then you protect the result.

What St. Louis Driving Does to the Bill

Local conditions genuinely move detailing prices, and they move them at predictable times of year.

Winter salt. Missouri road crews are not shy with brine, and it gets tracked into carpet, packed into rocker panels, and left to sit in wheel wells. Spring interiors around here take longer than spring interiors almost anywhere warm.

Highway grit. Anyone commuting on I-64 or I-270 is collecting rock chips and embedded metallic dust in the clear coat. That decontamination step is not optional here, and it adds time.

Spring pollen and summer organics. Tree sap, bug splatter, and bird droppings etch clear coat fast in July and August heat — we wrote about that in late-summer paint damage. Etching that has set in usually needs polishing, not washing, which moves the job into a higher price bracket.

Humidity. A damp interior in a St. Louis August grows odor fast. Catching it early is a $100 problem; ignoring it for a season is a $300 one.

How to Get a Quote That Holds Up

The best thing you can do is bring the car by. Two minutes of someone actually looking at your paint and interior beats twenty minutes on the phone. When you get a quote, it is fair to ask:

• What exactly is included? Specifically: is the paint being machine-polished, or just washed and sealed? That one answer explains most price gaps.
• What protection goes on at the end? A spray sealant lasts weeks. A quality paint sealant lasts months. A ceramic coating lasts years. Very different products, very different value.
• How long will you have my car? If the answer is “two hours” for a full detail, the package is smaller than it sounds.
• Is the price tiered by size? Almost always yes — confirm which tier your vehicle falls in before you commit.

One more thing worth considering: a maintenance schedule is cheaper than a rescue. Two moderate details a year usually costs less than one emergency deep-clean plus correction, and the car never gets far enough gone to need it.
