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).

If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

Repairs typically take 2-4 hours for small areas. Larger or more complex repairs may require additional time.

Whether Venetian plaster increases your home's value often depends on the buyer's preference. As a purely aesthetic upgrade, it doesn't add structural value in the same way a kitchen or bathroom remodel might. However, its beautiful and attractive appearance can make a home more appealing to potential buyers, possibly leading to more interest, higher offers, and increased competition when you sell.
