Plaster Repair questions, answered by experts

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).

There are several warning signs that a ceiling crack is connected to a larger issue. For starters, if the crack is wider than 1/8 inch or longer than 12 inches, you might have a more serious problem. The same applies if you have multiple smaller cracks or cracks going across the ceiling and down the wall. In any of these situations, you should ask a professional to assess the damage.

Regular inspections and cleaning to prevent moisture or pest issues.

Plaster walls last 30 to 70 years, although expertly applied and well-maintained plaster can last for centuries. That’s why it’s important to leave plaster installation to a pro, treat cracks as needed, and have a pro inspect any concerning cracks as soon as possible. These efforts can greatly extend the life of your plaster walls for decades to come.

If the water damage is small, such as small patches, you can paint over the area. To prevent mold growth, roll on a coat of an antifungal primer beforehand painting. However, if the damage is more extensive, you may have mold, and the plaster will be compromised. You’ll have to replace the plasterboard.
