"I recently had MGM Group plaster my ceiling that caved in out of nowhere. In short, I couldn't be happier with the results. They were very well-priced, quick to respond, and professional throughout the process. A special shoutout to Z, class all the way —will hire again no questions asked."

Plaster Repair questions, answered by experts

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

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.

Whether you can install or repair plaster yourself depends on the project's size and your comfort level with DIY projects. It's possible to handle small repairs on your own, but for larger projects like a room restoration or a full installation, it's often best to hire a local plaster professional. The final appearance, even coverage, and durability of the plaster depend heavily on proper wall preparation and application. If you are not 100% confident in your ability to achieve a professional result, letting an expert handle the job is a worthwhile investment.

If you already have plaster walls and ceilings, adding new plaster costs $2 to $10 per square foot. For an average-sized room, that would come out to $1,200 to $10,000. However, the cost to replace plaster with drywall is higher—running between $720 and $1,250 for a 10-by-8-foot wall or ceiling (not including drywall finishing).

Many services include repainting to match the existing surface. Confirm with your provider.
