Thanks for all the comments / suggestions. I'm feeling overwhelmed. It doesn't help that all of us are packrats and the house was a mess before all of this. Thank heavens Mr. Kay is better at managing this and keeping up with the workers than I am.
I hadn't thought of flame retardant on carpeting... that's one of the things we were told to avoid in pajamas for Tom, so I guess it's not recommended. I am leaning toward no carpet. (Mr. Kay would prefer going back to carpet.)
Anyway... just to keep you posted... they found asbestos in the flooring and wall tape. I guess I'm not really surprised, but it never occurred to me until yesterday. One of the workers asked us yesterday if we were the original owners. While I am a mere months away from 40, this house was built in 1953! (Mr. Kay is a few months younger; although to hear him talk, he's at death's door. "I'm getting old!"
)
So, we have to wait and see what the next step is. My fun meter is pegged.
