Gaps in crown molding — Elche, Valencian Community

Gaps between crown molding and the ceiling or wall are one of the most visible cosmetic defects in a home. They appear when the house settles, when seasonal humidity changes cause wood to expand and contract, or when the original installation was done poorly. While small gaps can be re-caulked as a DIY fix, recurring or widening gaps often indicate truss uplift, joist movement, or improperly nailed molding that needs a carpenter's expertise to repair correctly and permanently.
