invst4profitHiring a remediator without actually seeing the extent of the mold is overkill. It would take very little effort to open the ceilings to look without resulting in any risk.
I would carefully remove some drywall to visually inspect the extent, if any, before hiring any contractors. Mold is in fact not as dangerous as is commonly believed and providing it is not overly disturbed and one is not exposed for a extended period of time there is next to no risk. In addition there are actually very few molds that are actually dangerous.
There's no abestos, according to the samples takened. (drywall is non-containing).
I will get a second opinion and gather all options, but will have comply with the environmental officer who is aware of the situation now.
