3. Completely clean up mold and dry water -damaged areas
What are possible locations for hidden mold according to the EPA book? -
ANSWERpipe chases, utility tunnels, walls behind furniture, condensate drain pans
inside air handler, porous thermal/acoustic liners in duct, roof materials above ceiling
tiles
