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).

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.

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.

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.
