Foundation Crack Guide for Fort Wayne Homeowners
Crack direction, location, width, and change over time all provide useful context. A photograph cannot confirm the cause, but it can help you ask better questions.
Vertical Cracks
Vertical cracks may relate to concrete shrinkage or movement. Watch for widening, water entry, displacement from one side to the other, or related changes elsewhere in the home.
Horizontal Cracks
Horizontal cracking in a basement wall can be associated with pressure acting against the wall. Bowing, inward movement, or a crack that continues across a long section deserves timely professional evaluation.
Stair-Step Cracks
Stair-step cracks follow mortar joints in brick or block. Their meaning depends on location, width, displacement, and whether doors, windows, or floors nearby have also changed.
Diagonal Cracks Near Openings
Diagonal cracks extending from doors or windows can occur for several reasons. Note whether the opening sticks, the crack is growing, or exterior masonry shows a similar pattern.
Slab and Floor Cracks
Concrete slabs often develop cracks, but vertical displacement, widening gaps, water entry, or a noticeable change in floor level may justify closer examination.
How to Document a Crack
- Take a wide photo showing its location
- Take a close photo with a ruler for scale
- Record the date and approximate width
- Note rainfall, drainage, or indoor changes
- Do not cover the area before an evaluation
Seek prompt help when movement appears active, a wall is bowing, the structure seems unstable, utilities are affected, or you have immediate safety concerns.
