Plaster Repair questions, answered by experts

Costs range from $200 to $800, depending on the area size and damage severity.

Only use spackle on plaster walls when the imperfection is small. It’s best used for nail holes or small dings in the plaster. Spackle dries quickly, allowing you to continue the repair process shortly after using it. Plaster can be tricky to repair, though, so if you run into issues, call a pro so that you don’t risk further damage.

Drywall can be better than plaster if you’re installing a new wall and want to keep costs low. It’s much cheaper than installing plaster and provides a smooth, uniform surface. Many homeowners simply paint over the drywall or add a texture like sand or orange peel. It’s also much easier to DIY than plaster, and if you need to change your layout, it’s much easier to remove.

Small hairline cracks in plaster walls are not serious and are mostly cosmetic, but larger or widespread cracks indicate structural problems that need repair. 

  • Cracks 0.5 cm (0.2 inches) or thinner: Cosmetic cracks you can repair if desired.

  • Cracks wider than 0.5 centimeters or widespread cracks: Structural repair is needed, either DIY or by a pro.

  • Cracks 2.5 centimeters (1 inch) or wider: Contact a plaster repair professional.

Watch for large, deep cracks, multiple cracks in the same area, and cracks along the walls where they meet the ceiling. Repair these cracks to prevent further damage.

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.
