If you think your concrete foundation has a problem, ceiling sheet rock cracking, etc., it might be something as simple as keeping foundation watered via using a soaker hose next to house.
Lay of the land may cause house to be higher on one side. Ours is a few inches down in the back, no foundation cracks. Ceiling sheet rock is cracked all across the house.
Had a structural engineer check the house and it was determined front of house stayed more wet than rest of house (ground sloped toward the back). Too dry soil caused the difference.
Do not have a foundation repair place check your house because they want work and may tell you the foundation needs leveling when it does not. Worth every penny to pay a structural engineer, one that has no interest in repair work to check your house. Cost $275 for size house we had checked.
Thought I would pass this along in hopes it may be of help to others.
Now we need to put a soaker hose around the house except the front where yard watering keeps it damp enough. Need to let if slowly drip all the time. Will have house checked again in the spring and see if it has corrected the problem before repairing the sheetrock.
Wet ground swells and will make the difference.
