Picture 2, the walkway could be a trip hazard.

One picture shows that a door appears to be out of square somewhat.

As far as the others, nothing unusual but what I call a lack of pride in craftsmanship.

If the Structural Engineer is recommending piers, then I take his advise and start looking for a foundation repair company.

That soil out in Wylie moves like a roller coaster.

Ants are part of living in Texas. You see them, you kill them. I see dead ants in your picture. Mission accomplished.

I live in Rockwall, and am in Wylie several times a week if I can help you out let me know.
