Help Meghan's Grandparents Save Their Home

My names Meghan I'm raising money to help my grandparents keep there house. A couple months ago they noticed a soft spot in there living room. After getting it looked at by a contractor its covered with black mold and water damage. If they don't get it fixed they will be forced to leave there home and it will be condemned. The insurance company will not cover anything! My grandfather is a Vietnam war veteran, a retired cop and a retired corrections officer. Anyone that knows my grandmother and grandfather knows they would give the shirt off there back. They have already been scammed by a contractor that took them for a couple thousand. They have worked there whole life to provided for there family. To be there any time anyone needs anything.The money will go for the mold restoration, the rebuild of the living room and the new drain system that needs to be put in. This all needs to be done by the winter. Anything will help. They are trying to sell what they have but it's hard. My grandfather is also dealing with medical issues. Is having surgery in September and will be out of commission for a couple of weeks.
