It sure can! Old plaster that’s restored can increase your home’s historical authenticity. If yours is a Victorian-era home, don’t remove any of the plaster - this is very sturdy, buyers expect it to have it, and you may get a higher appraisal than other homes on the market. Should you build a new home, try using as much plaster as possible to make it more durable, require less maintenance and make your home more valuable.
