Do Cracks in Walls Indicate a Structural Problem?

Most small cracks in drywall or plaster walls are not serious and are caused by seasonal expansion and contraction of the wood framing in your house over time. They’re often found at the corners of window and door frames, and can be patched using spackling or joint compound.

Larger cracks in your walls, however, can indicate structural or foundation problems. If the cracks in your walls exhibit these characteristics:

  • The crack has a 3/16” or wider gap.
  • One side of the wall is higher than the other.
  • Your doors no longer close in the frame.

You may have a structural problem and should have your house examined by a foundation specialist.

    It is quite common for buildings and homes to shift over time and even tremors, jolts in the ground as when large vehicles pass through, can cause shifting in a foundation or a building. Weather conditions over the years can cause the same action. Thus moisture can seep through the cracks and cause mold. Once it starts, it keeps spreading until dealt with. A good mold remediation program along with structural fixtures can alleviate the problem.

    It’s interesting that most smaller cracks are generally caused by wood expansion or pressure on the walls. I didn’t realize that this could happen with the drywall, although, it’s very relieving. I’ll have to have a professional come out to re-plaster the walls and take a look just to confirm that they aren’t serious cracks.
