Vehicles and vessels

small cabin. big concentration.

In a car or a boat you breathe the volume of a small room, with the doors closed and an air conditioner recirculating the same air. Mold on the AC evaporator, in the carpet after a flood or in the mattress of a berth reaches the lungs at a concentration that would never be measured at home. A vehicle mold test measures the cabin against outdoors and says whether the smell is a nuisance or a problem.

Why looking is not enough

why cleaning does not fix it.

A musty smell in a car is usually treated with an AC spray, an air freshener or an interior clean. Each hides the smell for two weeks. None says what is growing and where.

What is on the evaporator

The car AC evaporator gets wet on every drive and dries slowly. The smell when you start the car in the morning is spores blown straight into your face. A sample at the AC outlet against the cabin proves whether it is the source.

What is under the carpet

A car that was flooded, or leaked from the roof or a seal, holds water under the carpet and in the floor insulation for months. The interior is dry to the touch, and the smell returns on every rainy day. A moisture meter reads it through the carpet.

Who is selling

The dealer, the garage and the private seller all want the car to drive away. The insurer wants to close the flood file. An independent lab result is what says whether this car is fit to drive with children in it.


What we measure

the cabin, the AC, and outdoors.

The test in a vehicle or a vessel is adapted to a small volume: short samples, comparison against outdoors at the same parking spot, and AC running versus off.


Car and yacht, two cases

from an AC that smells to a boat that sat through winter.

A car and a vessel are the same problem in two sizes: a closed volume, water that got in, and a system that recirculates air. This is what is tested in each, and what you get at the end.

  1. Car: the smell from the AC

    A cabin sample with the AC off, then a sample at the AC outlet after five minutes of running. If the concentration at the outlet is far higher, the source is the evaporator and the ducts, and the fix is a professional system clean and a new cabin filter. If the concentration is the same, the source is in the cabin itself.

  2. Car: after a flood or a leak

    A moisture meter through the carpet in every footwell and the boot, a swab from the carpet edge and under the seats, and species ID at the lab. Species of prolonged wetness say the water sat there for weeks, which is what turns a "cleaned" car into a car whose upholstery has to come out. The report suits an insurance claim and a price negotiation.

  3. Yacht: after winter in the marina

    A boat that sat closed for months is a damp cabin nobody opened. We sample every berth, the saloon and the engine room against the pontoon air. We measure moisture in mattresses, upholstery and hull linings, and check the bilge and the marine air conditioning.

  4. Yacht: before buying or chartering

    A marine survey checks the hull, the engine and the systems. It does not measure the air in the berth. A pre-purchase mold test records what grew inside and what it takes to clean, before a price is agreed. For a charter: documentation on handover day protects the deposit.

  5. The report: where it goes

    For a car: to the dealer or the garage treating the AC, to the insurer in a flood file, or to the buyer in a negotiation. For a vessel: to the marina, the charter company, the management company or the buyer. In both cases the report separates the system, the upholstery and the structure, so the right thing gets fixed.

One test costs less than a third AC clean that did not help, and far less than new upholstery for a car that did not need it.


What you receive

a report the garage and the insurer understand.

The report is written so a garage, a dealer, an insurer or a marina can act on it without coming back to us.

  • Results per sampling point: Cabin, AC outlet and outdoors, each with its concentration and species, from the partner laboratory. The difference between them is the conclusion.
  • A moisture map of the cabin: Moisture readings in every footwell, the boot, or every compartment of the boat, with location and date.
  • A conclusion on source and extent: AC system, upholstery or structure. What needs cleaning, what needs replacing, and what is sound. That is what prevents unnecessary upholstery removal.
  • An explanation by phone: For you, the garage or the adjuster. We do not repair air conditioners or reupholster, so we have no interest in the answer.

Before you book

What people ask about cars and boats.

There is a musty smell when I turn on the car AC. Is it dangerous?

The morning smell is spores and breakdown products that built up on the wet evaporator and are pushed into the cabin at start-up. Whether it is dangerous depends on the species and the concentration, and the test measures both: a sample at the AC outlet against the cabin and against outdoors. In most cases the fix is a professional clean of the evaporator and ducts and a new cabin filter, and the test says whether that is enough or the source is the carpet.

I bought a car and suspect it was flooded. Can you tell?

Yes. A moisture meter through the carpet in the footwells and the boot finds floor insulation that is still wet, and a surface sample from the carpet edge and under the seats identifies the species. Species of prolonged wetness, such as Chaetomium, say the water sat there for weeks. The report documents it with dates and locations, and suits a negotiation with the seller or an insurance claim.

Where is the test done for a car or a boat?

Where the car is parked or at the marina where the boat is moored. We bring the equipment, and the test takes half an hour to an hour for a car and one to three hours for a yacht, depending on the number of cabins. The outdoor sample is taken at the same spot, because the comparison has to be against the air around the car or the pontoon.

Is the test suitable before buying a yacht?

Yes, and it complements the marine survey rather than replacing it. The survey checks hull, engine and systems. Our test measures the air in the cabins, the moisture in mattresses and linings and the marine air conditioning, and identifies what is growing inside. The report gives a basis for a cleaning demand or a price reduction, and for a charter it records the condition on handover day.
