Plaster Repair questions, answered by experts

Common causes of ceiling cracks along drywall seams include poor drywall installation techniques, structural issues, truss uplift, and foundation problems. Temperature and humidity also play major roles in ceiling cracks flush with the wall. As the drywall shrinks and expands from major temperature changes or extreme humidity shifts, this can cause the drywall to crack.

To maintain plaster walls, inspect them regularly for cracks and seal them early. Clean the walls by dusting regularly or using a gentle, damp cloth. It's also important to avoid moisture exposure. Repainting as needed will help maintain the wall's appearance and longevity.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

On average, repairing a ceiling costs anywhere from $450 to $1,750. However, there are many variables that can impact the price of this project. For example, the type of ceiling material, type and extent of the damage, and local labor rates all affect your costs. Holes and cracks are less expensive to fix, while structural issues and water damage are pricier problems.

All plaster walls will crack over time due to normal house settling and expansion and contraction from temperature and moisture changes. Small, thin hairline cracks are generally not serious and are mostly a cosmetic issue. However, larger or more significant cracks can indicate structural problems.

Here's how to tell the difference:

  • Cosmetic Cracks: Cracks that are 0.5 cm (0.2 inches) or thinner are typically cosmetic.

  • Structural Cracks: Cracks wider than 0.5 cm, excessive or deep cracks, multiple cracks in the same area, or cracks that span around corners can signify a structural or foundation issue. Cracks along the joints where walls meet the ceiling also warrant attention.

For cracks wider than 0.5 cm, structural repair is needed. If a crack is 2.5 cm (1 inch) or wider, or if you notice any signs of a structural problem, it is best to contact a plaster repair professional to assess the damage.
