Whether a crack is structural or cosmetic depends largely on its orientation, width, and accompanying symptoms. While we often see vertical cracks that are purely cosmetic—resulting from the natural drying and shrinking of framing lumber—diagonal cracks at a 45-degree angle are a different story.

When it is likely cosmetic:

• In new construction, vertical or hairline cracks are common as the home “beds in” and materials cure. If these remain narrower than 1/8 inch and do not extend far beyond the frame, they are typically a sign of normal settling.

When it signals a structural concern:

• Diagonal patterns: Cracks that radiate from the upper corners of door frames are classic indicators of differential foundation settlement.
• Size and progression: Any crack exceeding 1/8 inch in width or one that continues to widen after cosmetic repair suggests active movement.
• Secondary signs: If you also notice sticking doors, gaps between walls and ceilings, or stair-step cracks in brick mortar on the exterior, the issue is likely structural.

Because Colorado’s expansive soils can exert significant pressure on a foundation, we recommend a simple monitoring protocol: measure the crack every 30 to 60 days. If your tracking reveals widening, professional intervention is necessary. We specialize in foundation stabilization using helical piers and tiebacks to stop active movement.
