A 1/4" crack in a concrete slab is not normal. Those cracks together
with the fact that a door is out of square would indicate that
something is significantly wrong and you should get a structural
engineer in. In many states, new homes have warranties that cover
varying types of defects for different lengths of time, structural/
foundation type being covered the longest. With a 2 1/2 year old
house, I'd get this addressed now.

I agree. trader4 has given you excellent advice.

The fact that the builder offered to fill the cracks
suggests there is some kind of warranty in place.
Check your contract, and the State requirements as
suggested.
