We can do detailing when there is mold in the vehicle however it likely will be an additional fee. This does not always occur depending on the severity however it often times can due to it being a bio hazard. You would still want to pick the detail package you would like to go with which with mold we would recommend going with our top interior package (elite interior detail) for the best cleaning however the package you choose is up to you. We would also suggest adding on the disinfectant add on to help kill the mold after the cleaning. The additional charge is for the bio hazard fee, not for the disinfectant process. Please note, we do not remove the carpeting, seats or padding however we can provide a very thorough cleaning. It will be vital that you leave the vehicle open and the mats out to allow it to dry completely and properly until closing it off. If you wish to speed up this process, you can always run the floor heater inside the vehicle. To get a quote for the additional fee, please send photos to info@nationaldetailpros.com and include your zip code. If you are not able to, you can book as normal however please include in the notes that you have mold so the detailer can come prepared and in this case, the detailer would let you know the added cost on site.
