Cracks
Watch for stair-step masonry cracks, horizontal basement-wall cracks, diagonal cracks from openings, widening gaps, and cracks that repeatedly return after patching. Location and movement matter.
Floors, doors, and openings
Floors that slope, doors that stick, windows that bind, or trim that separates can appear when framing or foundation elevations change. These symptoms can also come from humidity, framing, or normal building movement, so context is important.
Exterior changes
Brick separation, gaps around windows, a leaning chimney, or visible movement at a foundation corner can warrant a closer lookâespecially when several symptoms appear in the same area.
What to do next
Photograph cracks with a ruler for scale, note dates, and avoid repeatedly covering symptoms without understanding the cause. If changes are progressing or appear structural, request an on-site evaluation.
