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.

Professionals diagnose underlying causes, such as structural shifts or moisture problems, and apply appropriate solutions like reinforcement, patching, or sealing. These measures restore wall integrity and prevent recurrence, ensuring long-term stability.

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 may take a bit of patience and trial and error to match your particular drywall texture type when making repairs. For orange peel or knockdown finishes, use a spray texture product or a thinned joint compound applied with a roller or sponge. Practice on scrap drywall or cardboard first. Once dry, lightly sand and prime before painting.
