Most cracks in slabs are small expansion cracks that should not pose a problem. If the crack will show, it can be filled with a concrete repair caulk. However, if the crack is 1/4” wide or wider, and one side is higher than the other, you may have a settling problem that should be examined by a structural engineer.

  9. Hi, Joan,
    It’s hard to know what could be happening without being there in person, but here’s a tip regarding digging.
    If you choose to do this, first call 811 to make sure no utility lines are in the area.
    Take care!

  10. I am very worried about my home in Dfw Texas. The cracks I feel like have gotten significantly worst in the two years of home ownership and I am completely stressed about but my partners does not seem to be in a rush to fix anything.

    I have cracks in the bathroom tiles, cracks leading alone wall and ceiling crease and multiple corners, windows and door ways miss aligned. I also have one Inc the main living room that stretches diagonal and is spidering out.

  11. Hi, I need some advice. I sold my home last November located in Central Texas. It was lawfully sold through a realtor and past inspection. The home was built 1981 – I was the only owner. Other than small cracks in the interior walls I had no problems. I might have to add that I am a yard and plant nut and therefore kept my property well watered during the dry season. The new owner contacted me and informed me that several cracks have appeared outside in the brick walls. She has asked me to have them fixed or will contact a lawyer. The house was sold last November, but the new owner did not move in until sometimes in March of this year. I moved to Missouri, so I am quite some miles away to find someone to inspect the problem and find proper help. Any advice? The new owner sent me some photos, but I don’t know haw to add them to this post.

    • Hi, Solweig,
      It’s unusual for a buyer to make demands after a sale closes.
      You might want to contact an attorney for the best advice in this situation.
      Good luck.
