I just need some general advice on what I need to do to get started on repairing a very old home. I have already had to have the support structure under the house replaced because the back porch almost fell completely off. Then I noticed the coal fireplaces were bricked up with the coal left in them! I have bricks made of ? and morter made of ? that is crumbling all over the place. OK! I know, one thing at a time! Any information would be greatly appreciated!!! Thank You!!!
