Re: formaldehyde issue
This process you describe would make me very sick as I am very sensitive to formaldehyde, paints, and most construction materials. I feel for you, as is often the case with EI, it takes knowing ahead of time what to avoid to keep you safe whenever anything happens or changes. I say now that the damge is done, anything you can do to air it out and off gass the materials is better for you. Have you tried ozoning the area to speed that along?
Also, why don't they use something like GSE or Benefect to fog for the mold with rather than such harsh chemicals? I have personal experience with GSE, know it works and so long as I leave the area when it is being done and air out afterwards, I am fine. And I am pretty darn sensitive!
Hope it works out for you. You and your husband have done so much to make your home safe, you deserve a break!
Best wishes to you for a loving holiday season,
