We find where the moisture is getting in, open up the interior far enough to clean the material it soaked into, dry the vehicle under controlled conditions, and document what we found along the way.
Scope and cost depend on the vehicle's condition and what the inspection finds, so we don't publish a flat price for this work. In-shop service across the Portland metro. Valet pickup available.

A musty car is a wet car. The smell is the symptom — the water is the problem, and it is almost always somewhere you can't see from the driver's seat.
Portland gives vehicles a long wet season and not much drying weather in between. Water finds its way in through a blocked sunroof or cowl drain, a tired door or windshield seal, a taillight gasket, or a heater core or AC drain that has given up — and then it sits in the jute padding under the carpet, where nothing evaporates and nothing gets cleaned by a normal detail. Platinum Auto Care handles these as in-shop jobs: the vehicle comes to us, the interior comes apart as far as the findings justify, and it goes back together dry.
The Work
Six stages, start to finish
This is the shape an involved job takes. Not every vehicle needs every stage, and how far we go inside depends on what the inspection finds and what you approve. Many of the involved jobs we take in run around five working days in the shop — but drop-off timing, how wet the vehicle is, drying time, parts and findings all move that number.
01Inspection & plan
We look for the water before we look at the mold
The vehicle comes in and we go looking for the source. Moisture readings through the carpet and padding, floor mats up, trunk and spare well opened, headliner checked around the sunroof, and the usual entry points inspected — sunroof and cowl drains, door and window seals, taillight gaskets, windshield edges, and the HVAC condensate drain.
We photograph what we find and write you a scope: what we believe the source is, how far into the interior we need to go, what that costs, and roughly how long we will have the vehicle. Nothing comes apart until you have seen that and approved it.
Why this comes first: if water is still entering, anything cleaned and dried can get wet again. We would rather tell you that on day one than after the work.
02Exterior & initial work
Clean the outside so it stays outside
Before the interior opens up, the vehicle gets washed. Grit on the sills, door jambs and rocker panels ends up on the carpet the moment seats start moving, so the exterior comes first for practical reasons rather than cosmetic ones.
Inside, we bag and log your belongings, clear loose debris, and run a first vacuum and surface pass. That gives us a clean baseline and it often reveals staining and tide lines that were hidden under mats and clutter.
03Interior disassembly
Seats out, carpet up — as far as the findings justify
Under your carpet there is a layer of jute or foam padding sitting directly on the metal floor pan. It is absorbent by design, it is sealed in on all sides, and once it is wet it stays wet for months. This is where the smell lives, and there is no way to reach it from above.
So the seats get unbolted and lifted out, connectors are released and labelled, and the carpet comes up. Console, sill plates and lower trim come off where they block access. Sometimes that means the front footwells only. Sometimes it means the whole floor.
Scope varies: this is the stage that moves a quote the most. We show you what is underneath before we go further, and seat or carpet removal is only done when the findings call for it and you have approved it.
04Deep cleaning & drying
Physical removal, then days of controlled drying
Cleaning here means taking the contamination out of the material, not spraying something over it. Carpet, padding and upholstery get shampooed and hot water extracted, repeatedly on the bad areas. The exposed floor pan is cleaned and inspected for standing water, surface rust and failed seam sealer. Hard surfaces, vents and trim are cleaned by hand.
Then the vehicle sits in our shop with airflow and heat on it, apart, until the materials actually read dry on a meter rather than feeling dry to the hand. This is the part that takes days and it is the part that decides whether the smell comes back.
Conditional or separate scope: badly contaminated padding is sometimes replaced rather than cleaned. Cabin air filter replacement, HVAC odor treatment and drain clearing are quoted as add-ons. If odor remains after cleaning and drying, an optional controlled ozone treatment can be run as a finishing step — unoccupied, then ventilated before release.
05Reassembly & quality check
Back together properly, not just back together
Padding and carpet go back down dry. Seats are refitted with their hardware torqued to spec, connectors reseated and clipped, and trim, sills and console returned. Seat belts are checked for free travel and retraction.
Then it gets checked: warning lights and restraint system indicators, seat position and heating functions, windows and locks, and a walk of the interior in good light for anything missed. If something is not right it goes back apart.

06Ready for pickup
You get the vehicle and the paperwork
Final photos, and a walkthrough of what we found, what we did, and what we could not do. That last part matters: if the source of the water needs a repair we did not perform — a windshield reseal, a body seam, a sunroof cassette — you leave knowing exactly what it is.
You get the intake, disassembly and reassembly photos along with the written scope, in a form you can hand to an insurer if you are filing a claim.
A good interior detail is a real service and we sell plenty of them. It is just not the same job as this one, and buying the cheaper one first is usually how people end up paying twice.
The surface can look immaculate while the padding underneath is still wet.
Carpet the only layer a surface detail reaches
Jute padding absorbent, enclosed, stays wet for months
Steel floor pan where the water collects and sits
The water is under the carpet, not on it
Padding sits between the carpet and the floor pan. It is absorbent, it is enclosed, and it does not air out on its own. A detail cleans the face of the carpet; the wet layer underneath is untouched, which is why the smell comes back within a week.
Cleaning is physical, not chemical
Growth has to be physically removed from the material and the material has to be dried. Products help you do that. Nothing sprayed onto a wet, enclosed layer substitutes for opening it up, extracting it and drying it, and we will not tell you otherwise.
An unfixed leak undoes the work
If the sunroof drain is still blocked or the seal is still failing, the vehicle gets wet again on the next rainy week. That is why we start at the source and tell you plainly what still needs repair, even when the repair is not ours to sell you.
Scope
What we check, and what moves the price
We do not publish a flat rate for this work because two vehicles with the same symptom can be a two-day job and a two-week job. Here is what the inspection actually looks at and what shifts the number.
Where we look for water
Sunroof and cowl drain channels
Door, window and windshield seals
Taillight and trunk lid gaskets
HVAC condensate drain and heater core
Floor pan seams and grommets
Trunk floor and spare tire well
What moves the scope
How much of the floor is affected
Whether padding can be cleaned or must be replaced
How many seats and rows have to come out
Drying time the materials actually need
Whether trim or parts are needed
How long the vehicle has been damp
Conditional & separate scope
Drain clearing — often included, quoted if involved
Seat and carpet removal — only when findings require it
Cabin air filter replacement — add-on
HVAC and odor treatment — add-on
Optional controlled ozone finishing step — add-on
Leak repair, glass and body work — separate, often another shop
Documentation
You see what we saw
Most of this work happens in places you will never look at again once the carpet is back down. So we photograph it: the vehicle at intake, the moisture readings, what was under the carpet once it came up, the floor pan with everything out, and the interior back together at the end.
Those photos go to you with the written scope — what we found, what we did, what we did not do and why. If you are filing an insurance claim, that is the package you hand your adjuster. Tell us before we start if they need something specific captured.
We do not currently have a self-serve client status page. If you want progress updates while your vehicle is with us, say so at drop-off and we will text you photos as the job moves.
Most of the five days is this: the vehicle sitting open, apart, with air moving through it.
FAQ
Questions we get before drop-off
Many of the involved jobs we take in run around five working days in the shop. That is an expectation, not a fixed schedule. The real number depends on when the vehicle is dropped off, how wet it is, how long the materials take to dry, whether parts are needed, and what we find once the interior is open. We give you a timeline with your written scope and tell you if it changes.
Sometimes. If moisture and growth are confined to surfaces, they may not. When water has reached the padding under the carpet, removing seats and lifting carpet is the only way to physically reach and clean the affected material and let it dry. We decide that at inspection, show you what we found, and get your approval before we take anything apart.
Not automatically. Our inspection identifies the likely point of water entry and we tell you what we found. Clearing blocked sunroof or cowl drains is often something we can handle as part of the job. Actual repair work such as replacing seals, windshield or sunroof glass, or body and sheet metal work is separate scope, and some of it is better done by a glass or body shop. If the water is still getting in, anything we clean and dry can get wet again, so we would rather you know that up front.
Musty odor usually comes from wet material and microbial growth in it, so the odor tends to improve as the source is physically cleaned and the vehicle is dried. If odor is still present after cleaning and drying, we can run an optional controlled ozone treatment in the shop as a finishing step, with the vehicle unoccupied and ventilated before release. Cabin air filter replacement and HVAC odor treatment are conditional add-ons we quote separately.
It can, if water keeps getting in. Cleaning and drying address what is in the vehicle now. They do not stop an unrepaired leak, a blocked drain that re-blocks, or a vehicle that is parked wet with the windows open. That is why the inspection starts with the moisture source and why we tell you what still needs repair.
We photograph the vehicle at intake, during disassembly and at reassembly, and we give you those photos along with a written scope of what was done. Customers do submit that documentation to insurers. We are not an insurance adjuster and we cannot tell you whether a claim will be covered or approved. If your adjuster needs something specific in the paperwork, tell us before we start and we will try to capture it.
No. An interior detail cleans the surfaces you can see and touch. Remediation work assumes the problem is underneath: trapped water in carpet padding and under the floor covering, and a point of entry that put it there. It generally involves disassembly, extraction, controlled drying over days rather than hours, and documentation. It also costs more and takes longer, which is why we inspect first rather than quote off a photo alone.
We look at them. Vehicles that have been standing in water are assessed individually, because water that has reached wiring, control modules, seat belt retractors or airbag components is a mechanical and electrical problem as well as a cleaning one. In some cases the honest answer is that remediation is not the right spend on the vehicle, and we will tell you that rather than take the job.
Text photos to (503) 395-5572. Useful shots are the footwells front and rear, under the floor mats, the trunk or cargo floor and spare tire well, the headliner around the sunroof, and anything visible you are concerned about. Tell us the year, make and model and how long it has been damp. We will tell you what we think we are looking at and what an inspection would cost. Scope and price are confirmed in person, because the inspection is what determines the work.
This work is done in our shop, because it needs controlled drying and a place the vehicle can sit partly disassembled. Valet pickup and drop-off is available if getting the vehicle to us is the problem. Ask when you request the inspection.
