Foundation problems are common in the Houston area. Unfortunately, our soil is not foundation-friendly! The original section of Wilderness Trails is not really different than any other neighborhood where the homes are the same age as yours. The first homes built in the "Pines" section did have a lot of foudation problems. The builder eventually started building the homes with builder's piers and extra-enforced slabs. Those homes have been okay so far (knock on wood...I live in one of them).
I have a foundation company that I recommend to my clients. I will be happy to give you their name and contact info. You can email me at firstname.lastname@example.org and I will send it to you. Good luck!
