My daughter, son-in-law and 1 year old grandson live in an older house with another couple. The property they live on includes a smaller house that needs a lot of work. My son-in-law began to remodel the smaller house in hopes of purchasing it when done. He removed all of the sheet rock which was painted with paint that contained lead. He also used a belt sander on floors and trim. A lot of this work was done with windows and doors wide open and the debris from this work was stacked in the front yard for several days before being hauled away. They also did a lot of sanding on the exterior paint which may or may not have contained lead in one of the layers. Because he did not know better, he took no precautions when going home. He picked up the baby in dust covered clothes and I am sure tracked a lot of dust into the other house. All of this has gone on over about 6 months. At a recent doctors appointment my grandsons lead levels came back very high.
My question is this. Can the home he was remodeling and the yard around it ever be made completely safe? Also, how dangerous is the home they are living in and can it be made safe? Also, if the homes and yard can be made safe, can someone give me a ballpark figure as to how much this can cost? The yard is very large, perhaps an acre?
