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.

Smaller is better when patching holes with spackle. Any holes wider than four to six inches in diameter tend to be too wide to repair with spackle alone. You'll likely want to patch bigger holes with a drywall panel. 

Even holes measuring up to 6 inches may be challenging to fill with spackle alone. For best results, purchase a wall repair patch made from wire mesh. Cut the patch to fit over the hole, then use the spackle to hold it in place. Apply the spackle over the patch as you would for a smaller hole.

If you already have plaster walls and ceilings, adding new plaster costs $2 to $10 per square foot. For an average-sized room, that would come out to $1,200 to $10,000. However, the cost to replace plaster with drywall is higher—running between $720 and $1,250 for a 10-by-8-foot wall or ceiling (not including drywall finishing).

The cost to repair a ceiling after a water leak can vary, with averages ranging from $419 to $1,359, or $45 to $55 per square foot. Smaller patches may cost around $150. The final price depends on the size of the affected area and the extent of the damage. Remember that you will also need to repair the source of the leak, such as roof damage or a plumbing issue, which can cost an additional $200 to $1,550. Depending on the situation, you might also face costs for repainting or repairing floors. For an accurate estimate, it is best to get a quote from a professional.
