My wife and I decided to build a house about two years ago. We didn't do our homework and we picked a lousy contractor. Anyway the house finally got done and we moved in. A little over a year later I noticed a LARGE crack running across the basement floor and some minor cracks running up the wall. We contacted Taylor Homes (who we contracted to build the house) and was told that concrete was going to crack and since our one year warranty expired we are on our own. My question is this: Is my foundation sagging causing my floor and wall to separate and if so what can I do to repair the problem and at what cost? I'll be the first to admit I don't know a lot about building or repairing homes but I did learn to do my homework. Any and all help is appreciated.
