We noticed this black stain which is likely mold behind where base boards used to be. We temporarily removed the baseboards to do reflooring. What should we do before putting up the baseboards again after we are done with reflooring? The contractors told us they can just “scrape it off” and don’t think it’s an issue. We are doing this remotely so we are not there to look at it in person. Here are some of the options we thought of doing.
Listen to the flooring contractors and let them take care of it
Have a cleaner come in and clean it using the mold-remover spray and other clean products
