Costs depend on damage size, labor rates, and whether additional services like painting are required.

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.

While certain types of textured walls can seem dated (looking at you, popcorn), textured walls are a common sight in both older and more modern homes. The main reason textured walls may be here to stay is that they are an excellent way to hide minor imperfections on a wall and give it a finished appearance. Some homeowners think a coat of paint on drywall is a bit industrial-looking. However, that look works perfectly in modern home design. 

The two most common drywall thicknesses for ceilings are 1/2-inch and 5/8-inch. For most standard residential applications, 1/2-inch drywall is sufficient and widely used. It provides adequate support and is lighter and easier to handle during installation compared to thicker sheets. However, 5/8-inch drywall is often used for specific cases where additional benefits are needed. It is heavier but provides superior sound dampening and fire resistance. You should consider using 5/8-inch drywall for ceilings in commercial buildings, between a garage and a living space, or above a finished basement to meet building codes or for enhanced soundproofing.
