Last Feb., I bought a 2-story house with crawl space. The house is about 12 years old. Recently I have discovered signs of foundation problem (settling?) that worry me a lot. 1. The floors at the family room and master bedroom(2nd floor) begin tilting. I did not notice this when we moved in. 2. Cracking sounds from the wall with chimney. At night, especially during earling morning hours, I can hear cracking sounds from the wall. Recently, the temperature drops some, but not below zero yet. The lowest temperature is around 36 to 40 degree. 3. some cracks at the corner of walls inside the house. Most of the cracks at the corner of walls are hairy, but 1 or 2 are bigger than that. 4. A crack (1/5 inch wide, several feet long) at my back yard.
We just moved in this house for several months. The inspection report said everything was fine. Should I call a construction engineer to have an inspection? What's your idea?
