The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.

The cost to repair a ceiling after a water leak can vary, with averages ranging from $419 to $1,359, or $45 to $55 per square foot. Smaller patches may cost around $150. The final price depends on the size of the affected area and the extent of the damage. Remember that you will also need to repair the source of the leak, such as roof damage or a plumbing issue, which can cost an additional $200 to $1,550. Depending on the situation, you might also face costs for repainting or repairing floors. For an accurate estimate, it is best to get a quote from a professional.

Common causes of ceiling cracks along drywall seams include poor drywall installation techniques, structural issues, truss uplift, and foundation problems. Temperature and humidity also play major roles in ceiling cracks flush with the wall. As the drywall shrinks and expands from major temperature changes or extreme humidity shifts, this can cause the drywall to crack.

You’ll want to inspect your plaster walls for signs of damage before painting. If you notice soft spots, deep cracks, bubbling, or areas where the plaster is crumbling or pulling away from the wall, it likely needs repair. While small hairline cracks are common and likely cosmetic, you should address larger issues before painting to ensure a quality, smooth finish.
