What must be done if there is a significant crack in the foundation?

When a significant crack is present in the foundation, further professional evaluation is necessary to assess the structural integrity of the building. Such cracks can indicate underlying issues like settling, shifting soil, or water intrusion, which can lead to serious problems if not addressed. A professional, such as a structural engineer or foundation specialist, can determine the cause of the crack and recommend appropriate remedial measures.

In contrast, ignoring the crack can lead to worsening conditions. Applying a sealant may only provide a temporary fix without addressing the root cause of the problem. Informing the insurance company may be prudent in some cases, but it does not directly resolve the structural issues the crack presents. Thus, obtaining a thorough evaluation ensures that the necessary steps are taken to maintain the safety and stability of the building.
