hi guys, i have a little question. i had one wall unfinished with just insulation and no vapourbarrier for most of the winter. just now i want to finish the wall up and notice balck mold behind the insulation. i checked behind another wall that had the vapour barrier and no mold. this is because of the vb not being up and condensation happening right?? what should i do before closing up the wall now?
