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.

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

Repairing plaster walls or ceilings is almost always worthwhile. It restores the appearance of your home, and if it's an exterior wall, the repair can improve curb appeal and provide a great return on investment when selling. Plaster repairs can also reinforce the wall, preventing minor cracks from spreading, and improve your home’s energy efficiency by fixing gaps in the insulative material, potentially lowering your heating and cooling bills. Additionally, hiring a professional allows them to check if the damage is from a serious underlying issue, such as foundation instability. Catching a problem like this early could save you thousands.

Common causes include water leaks, settling, and impact. Address underlying issues to prevent recurring damage.
