Wall Separation from Ceiling/Floor
Short answer
When walls visibly pull away from ceilings or floors, the home's framing has distorted. Causes include foundation settlement, roof truss uplift, and crawl space movement.
MODERATE: Hairline seasonal gaps are often truss uplift. Permanent or growing gaps are structural.
What it is
Wall separation is a visible gap between the wall plane and the ceiling or floor — typically appearing along the top of an interior wall or where the baseboard meets the floor.
What causes it
- Foundation settlementDrops the wall relative to the ceiling.
- Truss upliftSeasonal moisture changes cause roof trusses to lift in winter.
- Crawl space sagDrops the floor relative to the wall.
Diagnostic checklist
- Measure the gap at the widest point
- Note whether it changes seasonally
- Check both the ceiling and the floor
When to call a professional
Call when gaps exceed 1/8 inch, are permanent, or are paired with exterior cracks.
DIY vs professional
Crown molding can hide a gap, but does not solve the cause.
Arkansas context
Truss uplift is common in Arkansas because of our humidity swings.
