A sagging or bowing ceiling is one problem you should not wait on — it usually means water, a failed fastener job, or a load issue above, and a heavy section can come down. Here is what causes it and how it is properly repaired.
A leak above soaks the drywall and insulation, and the added weight pulls the ceiling down.
Too few screws, or old adhesive on older ceilings, let the drywall pull away from the joists.
Storage or movement above, or truss uplift, can stress the ceiling and cause sagging.
Repairs range widely — $400–$2,000+ — based on the cause and area. Water-related sagging includes drying and insulation work.
A saturated or detached ceiling section can collapse without warning, risking injury and damaging everything below. This is a call-now problem.
