I was in the process of scraping paint from my wood floors in a century old house. Today we tested (test from hardware store)for lead. It tested WAY positive. So we've (my family including kids and pets) have not only been inhaling the dust, but all the windows test positive as I would imagine all the floors (LARGE AREA)and I sit up all night wondering the next step and how much $$$??? Any advice on the removal of lead paint and the best options now? Thank you.
