"Shawn came to work on my washing machine that wasn’t operating. When the first repair didn’t fix the problem, he did more research and came back with another part that fixed the problem. I appreciate his communication about scheduling and about ordering necessary parts. I appreciate his commitment to solving the problem. And, I appreciate his work ethic. I would recommend Shawn to anyone in need of handyman type repair."

Plaster Repair FAQs, answered by experts

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. 

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.

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.

Repairs typically take 2-4 hours for small areas. Larger or more complex repairs may require additional time.

There are several warning signs that a ceiling crack is connected to a larger issue. For starters, if the crack is wider than 1/8 inch or longer than 12 inches, you might have a more serious problem. The same applies if you have multiple smaller cracks or cracks going across the ceiling and down the wall. In any of these situations, you should ask a professional to assess the damage.
