We have just found out that the strange odor we have been smelling inside our house off and on for the past few weeks is probably due to mold that accumulated in the crawl space ceiling and ceiling insulation due to a plumbing leak that raised the moisture level.
We know that we have to have the contaminated areas treated by professionals who come with special uniforms and face masks to remove the bad insulation and cart it away in sealed bags, and then clean the surfaces that are affected.
But we believe we need to go a bit further to assure ourselves that we have eradicated the contamination to make sure that it hasn't spread. We are especially concerned that the contamination might have gotten into the HVAC system. That would mean that we need to have the ductwork cleaned.
We want first to hire an impartial inspection company that can do the necessary measurements and interpret the results for us, but we prefer to hire someone who does not actually do the decontamination work because of the conflict of interest.
Any guidance from someone who has been through this issue would be most appreciated.
