"Pablo worked with me to customize the fence and deck replacement following storm damage. He repaired things I hadn't known were wrong and worked with my neighbors to ensure they were not losing property use during or after construction."

Plaster Repair FAQs, answered by experts

Only use spackle on plaster walls when the imperfection is small. It’s best used for nail holes or small dings in the plaster. Spackle dries quickly, allowing you to continue the repair process shortly after using it. Plaster can be tricky to repair, though, so if you run into issues, call a pro so that you don’t risk further damage.

You can put certain types of plaster over other types, but doing so isn't always the best idea. For example, putting a coat of gypsum over lime plaster is possible, but doing so will limit the lime plaster's breathability and potentially affect its performance.

Since cement plaster tends to leave a textured surface, no matter how much you smooth it, some people prefer to use gypsum plaster as a topcoat over cement plaster, creating a smoother surface.

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).

Your walls are likely cracking due to fluctuations in the temperature outside. Drywall tends to expand and contract when temperatures and humidity levels change, and this repeated movement can lead to cracks in your walls, particularly around door frames. If you have multiple diagonal cracks, you may want to have your foundation inspected, as cracks can also be a sign of a bigger issue.

Venetian plaster is a highly durable wall finish that becomes a rock-like substance once dried, making it last longer than most other wall finishes. Its lifespan can range from decades to centuries, potentially lasting a lifetime. Key factors influencing its longevity include the quality of the initial application, whether it's properly sealed against moisture, and how the wall is maintained and treated (e.g., how often it is touched or bumped). Due to its mineral content, it can also develop a patina over time.
