We have a rather large area of the house newly covered with Pergo-type floating laminate flooring (don't think it uses glue!), done about 2 weeks ago. It was placed over concrete slab foundation. When we moved in the house about a week ago, we noticed this nauseatingly sweet smell, not very strong, but enough to make you disgusted, mainly in the living room, which is the largest room in the house. I stuck my nose to the floor and the smell seems to be coming from the new floors, but it's hard to tell. My husband was worried about black mold, because the previous owners said they had a leak which was fixed, but we didn't see any evidence of mold or moisture anywhere in the house, in fact everything looks dry and there's no musty or earthy smells, just this sweet smell in the living room. Is it just newly installed laminate wood flooring or can it be something else?
