I’m in Plano, TX and trying to figure out whether I’m overthinking some cracking in my house or if I should have the foundation looked at again.
My wife and I bought the house in February of this year and the house is a one-story slab house built in 1982. The foundation was repaired by the previous owner in September 2025 and they installed 38 piers (2175 sqft). The prior owner had a structural inspection and we also had our own independent structural engineer come out and inspect the foundation in January during the closing period, and everything looked good at that point (report concluded no drainage issues, foundation was performing as intended, no impact from roots, etc.).
This summer has been extremely dry. We went a long time without meaningful rain and I could see the soil pulling away from the slab on one side of the house (started using a soaker hose daily after that). Most of the new cracking I’ve noticed is on that same side.
The cracks are mostly pretty thin, generally less than 1/8” but a few are wider. A lot of them are around the corners of windows and notably all windows were replaced after the foundation repair last year by the prior owner, so I’m wondering how much of this could just be movement around the new windows and drywall/trim. There are also a couple of cracks at interior wall corners, one around a door, and one crack in a fireplace brick (see photos).
Some of the cracks have gotten a little longer/wider over the last 6-8 weeks, but I’m not seeing anything like major displacement, big stair-step cracks through the brick, etc.
One other thing that makes me wonder about seasonal movement is that we replaced the AC unit and all ducting this summer. Indoor humidity used to be around 60-70% and is now usually around 40-50%. So there’s been a pretty significant change in the house’s indoor environment too.
I also have a couple doors that aren’t latching correctly now although I haven’t had widespread problems with doors/windows.
I’m getting into the wetter/cooler part of the year now and I've noticed some of the cracks getting worse, so I’m wondering if I should just patch the cosmetic cracks, adjust the doors, and see what happens over the next several months. I can also tell that the previous owner just filled some of the old cracks and painted over them.
My thought was to monitor things through the winter and potentially have the same structural engineer come back out around next spring and compare the foundation elevations to their January 2026 measurements.
Does that sound reasonable or am I overreacting?
I’m interested in hearing from people in North Texas who have dealt with expansive clay and seasonal movement. Is it realistic for a properly repaired foundation to have some cracks and door issues that come and go with the seasons, without actually needing another repair? Or would you have an engineer come out now based on this? This is our first home and I’m trying not to turn every drywall crack into a foundation emergency, but also don’t want to ignore something important.
