A repair plan will most likely involve closing off any ventilation grills with sheeting and duct tape and shutting down your furnace so that the blower doesn’t spread spores and dust throughout the home, as well as removing everything – furniture, pictures, lamps, etc. – from the affected room.
A most effective way to contain the affected area is to tape poly sheeting on all four edges of the door opening and having a slit cut up the middle from top to bottom.
If the moisture source is due to previous or recent water damage (such as a burst pipe or hurricane damage), contact a water damage mitigation expert.
