Symptoms
- Small cracks appearing within the first one to two years of a new home
- Cracks often at corners, ceiling seams, or above doors and windows
- No structural issues like sticking doors or uneven floors
Likely causes
- CommonLumber drying and shrinking after constructionNew framing lumber has moisture in it that dries out over the first year or two, causing minor shifting.
- CommonNormal settling of a new foundationNew homes settle slightly as the ground and structure adjust to the building's weight.
- PossibleRushed drywall finishing before full dryingIf drywall was finished before framing fully dried, cracks can appear as it continues to move.
What to do
- Note where cracks appear and whether they're widening over time.
- Wait until after the first year, since many settling cracks appear and stabilize in that window.
- Widen small cracks slightly with a utility knife so filler can grip.
- Apply mesh tape and joint compound over the crack, feathering the edges.
- Sand smooth once dry and apply a second coat if needed.
- Prime and repaint to match.
- Check your builder's warranty, since many cover cosmetic settling cracks in the first year.
