Hi, a few years ago my grandmother noticed termites in her home, the exterminator got rid of them and it wasn't until about a year later I noticed the floor was rotten in her bedroom closet. The damage runs a little ways out into the bedroom also, I have been underneath to see how bad it was, and the area is only about 2 feet up from the ground. Now there is a big hole in the closet floor that I have covered the best I could, but the joists are just dust now and I have no idea what to do to support it, putting down new chip board down inside the house is no big deal. But I don't know what to do to support it underneath. I'm so afraid that, that entire corner of the room is going to cave in. Anybody who has any ideas, it will be greatly appreciated.
