Mold Remediation in Cars

Water puddleLet’s talk about something exciting today – mold remediation in cars. Or, as most people call it, mold removal in cars. If you’re like me, then you have no idea how often mold occurs in our automobiles, that is, enough mold so that you have to take it somewhere and have the car cleaned and treated.

I thought these instances were quite rare, and pretty much limited to instances where a car was flooded, or, left outside during a two-day rainstorm with all the windows down.

But, after talking with Neal Ailstock, owner of Seatco, about mold remediation in cars, he states that Seatco sees around 10 vehicles a month come in for mold remediation, and most of those jobs happen because a sunroof drain or a drain attached to the AC system or some other drain in the car gets blocked, and water being water, it seeks someplace else to go. That location is almost always within the interior cabin.

Carpets and seats get wet, it’s a closed environment so the interior can’t dry out quickly, and mold occurs. It smells bad, and sometimes it’s enough mold so that it makes people sick.

The vehicle shows up at Seatco, and the guys here go to work.

This is what usually happens when Seatco performs mold remediation in cars:

  1. The whole interior of the vehicle is completely stripped out, including the headliner. Sometimes the headliner is left in, but this is on a case-by-case basis.
  2. The interior is thoroughly scrubbed with germicide.
  3. The interior is thoroughly scrubbed with anti-mold solution (Seatco uses a brand called Moldstat, but there are other options).
  4. The AC system is flushed with ozone
  5. The carpets are pressure-washed with germicide, or if necessary, replaced with new material.
  6. All door panels, seats, etc. are also treated with germicide.
  7. Moldstat is applied to both sides of carpet.
  8. A new jute mat (goes under carpet) is installed in the vehicle.
  9. Re-installation of the interior pieces is then accomplished.

Sometimes, one of these steps needs to be repeated, and sometimes the sequence is juggled a little bit, but this is the usual process.

Of course, as all this is happening, other technicians diagnose the cause of the leak and repair same.

How long does this take?

Anywhere from 3-7 days, depending on the drying time needed. For example, if it’s the middle of the hot summer, and it’s not raining, everything dries much more quickly.

And the big question, how much does all this cost?

The average is around $1200. Could be less, could be more, but the average is around $1200.

And that’s it. The customer drives out of here with a dry, fresh-smelling car, the mold has been banished, and everyone breathes a bit easier.

    Very, very informative post! I wondered how a professional shop takes car of mold. There are videos of mold removal on YouTube, but they’re by individuals and not as detailed as what you do, not by a long shot. I had a car that actually had little mushrooms growing in the carpet after it got wet and was parked in a garage, and the whole interior had to be redone. Expensive.

    1. We’ve seen cars that bad in here, with plant life growing in the carpets or the seats. It’s amazing how quickly a wet car can get really awful inside.

    2. I thought about your comment last week as we had a car come in here with fungus inside and plant life growing in the vinyl top. Mold removal was probably understating the case in terms of what we did to that car.

    Mold is not only unsightly and smelly, but can also be dangerous to breath in the spores due to allergies or other reactions, so knowing how to remove mold from car seats, carpets and the interior as soon as possible is a must do on your priorities list, but which way is the best to remove it?

    I have a Colorado. 2004. One row of seats and no carpet. I have molded vynil flooring. No carpet. Needs pulling and maybe replacing. Would it still be as much as 1200? Only 4 bolts on each side to get the seats out and not a lot on it.

    I have a VW BEETLE CONVERTIBLE that has a canvas top that got dry rotted and window came loose in back. Windows were stuck halfway down and rain got in car. Mold is growing in car and top. Which needs replaced, but have to get mold taken care of first. It cant be driven not safe to be in car. Probably have to get it towed. I live in calvert county md. Do you know if insurance pays for water damage? Does your company ever tow a car to your shop?
    Thanks for any information you can give me.

    1. Matt Lupton says:

      Hi Dee, Matt here. Happy to help you with that. Most of the moldy vehicles we work are handled by insurance carriers, yes. We ourselves do not provide a towing service, that would be up to your carrier to handle that.
