Plaster Repair questions, answered by experts

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.

Applying plaster to a wall will usually cost between $2 and $10 per square foot for both the material and labor. The cost will vary based on the quality of the plaster you’re using and whether or not prep work is required before the work begins. Wall prep can add up to about 10% to your total costs. Plastering exterior walls can be more expensive in many cases because they are taller and require scaffolding and safety equipment.

Plaster is a pretty tough surface, but it can still sustain damage from things like bumping against it, water issues, dampness, extreme humidity changes, and plain old age. Most plaster walls last hundreds of years and will only be taken down to the base layer when major repairs are required. Being cautious around the wall, not placing furniture against it, and ensuring stable humidity are all great ways to reduce possible damage.

Yes, you can use drywall repair techniques for some types of plaster damage. Tiny holes and small cracks in plaster can be patched in similar ways to drywall. You apply the necessary compound to fill the hole, wait for it to dry, then sand it down. For larger damage, like water damage or mold, you need to use plaster-specific techniques and materials.

Regular inspections and cleaning to prevent moisture or pest issues.
