I know absolutely nothing about anything when it comes to houses. One side of my house is bowing. Not too bad at the front or back end, mostly in the middle. A friend who looked at it said I have bad joists, and to get rid of the house. Is it possible for them to only be bad in one spot? I also need a new roof, and the base plate around basement floor is rotting also. I have no idea who to contact to do this kind of work (the joists), or how much it should cost. Any ideas? I live near Buffalo, NY
