"Paul Kothrade contacted me via telephone right away and met with me at our home soon after. He presented an estimate for the work we discussed. My wife and I reviewed it and asked them to proceed. They came to our house at a time that worked for us and they completed the work quickly and very thoroughly. I would have Kothrade Construction do any project we need in the future, no questions asked."

Plaster Repair FAQs, answered by experts

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.

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.

Plaster ceilings can sag for several reasons. In some cases, the plaster and other building materials shift and come apart over time, which is why you’ll commonly find drooping plaster ceilings in older homes. Improper installation, foot traffic, and water damage—often from a leaky roof or a broken pipe—can also cause plaster ceilings to sag.

While it is possible to repair minor plaster cracks or holes yourself, it is generally not recommended for larger jobs or if you want a professional result. Plaster repair can be difficult in practice; proper wall preparation and achieving a smooth, seamless finish that blends with the existing wall requires experience, especially on textured surfaces. Hiring a professional ensures the repair will be durable and last longer, potentially saving you money over time. A pro can also determine if the cracks are from normal expansion or a more serious underlying issue.

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.
