But in my opinion, I don't care how good a company is at duct cleaning, they're never going to clean that duct work well enough if there is ductwork that has mold in it and they bring in their machine and they clean those ducks and they go ahead and treat that ductwork with some microbial treatment and all the stuff that they can do. In my opinion, it's hard for them to guarantee 100 percent that every mold Spore has gone from that ductwork.
So what do we do ?
I agree with you there’s no way to get all the mold spores out. The only way to get rid of the mold is to change out the ductwork.
