• These are thin, surface-level cracks that commonly appear due to concrete shrinkage as it cures.
• They are usually not a structural concern but should still be monitored for changes.
• If they grow wider or start leaking water, they may need to be sealed to prevent moisture intrusion.

• Vertical cracks that run up and down your foundation walls are typically caused by normal settlement of the home.
• If they remain under 1/4 inch wide and do not expand, they are usually not a major concern.
• However, if they continue to widen or show signs of moisture penetration, they should be evaluated.

• These may indicate significant movement or shifting in the foundation.
• If a crack continues to widen over time, it may be a sign of structural failure.
• Professional assessment is recommended to determine if repairs are needed.

• These are among the most serious types of foundation cracks.
• They often result from excessive pressure from soil or water buildup outside the foundation walls.
• They can indicate that the foundation is bowing or at risk of failing.
• Immediate professional intervention is needed to prevent further damage.

• These cracks appear in a zigzag pattern along mortar joints in block or brick foundations.
• They often signal differential settling, where one part of the foundation sinks while the other remains stable.
• If they continue to widen, they may indicate shifting soil conditions or poor foundation support.

• These cracks typically run at an angle and are often caused by uneven settling.
• They can be minor if small and stable, but if they grow wider or show signs of movement, they may need repair.
• Diagonal cracks are more concerning if they appear in conjunction with other structural issues, such as misaligned doors or windows.

• Small cracks in concrete slabs are common, but large or expanding cracks can indicate foundation movement.
• If a crack is wide and runs across the entire slab, it may be a sign of serious settlement issues.
• Slab cracks that cause uneven floors or create tripping hazards should be inspected.

• Any crack that continues to widen, lengthen, or deepen should be considered a red flag.
• Measure cracks periodically to track changes.

• If water is leaking through cracks, it can lead to mold, mildew, and foundation weakening.
• Efflorescence (white powdery residue) around cracks is a sign of water movement.
• Proper drainage solutions, such as exterior waterproofing or sump pumps, may be needed.

• If cracks are accompanied by difficulty opening or closing doors and windows, it may signal foundation movement.
• Gaps appearing around window frames or doorways can also be a sign of shifting.

• If floors become uneven, it could indicate that one section of the foundation is sinking.
• A noticeable tilt or separation between the floor and baseboards suggests movement.

• If walls appear to be pushing inward, it is a sign of excessive pressure from the surrounding soil.
• This is a serious issue that requires immediate attention to prevent collapse.

• If cracks are present along with sagging ceilings, cracks in interior drywall, or gaps between walls and floors, it could mean severe foundation shifting.
• Multiple symptoms appearing together often indicate a major structural concern.
