Drywall Insulation FAQs, answered by experts

You should stagger drywall sheets to help prevent cracking. The joints between drywall sheets are the weak spots, so if you install drywall with seams aligned, you’ll create weak lines that run across the length of the wall and extend from floor to ceiling. But when you stagger drywall, the solid sections of panels will support the joints. This can prevent seams from cracking or separating due to fluctuating temperature and humidity, vibrations from movement inside the home, and gravity.

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.

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.

You can repair plaster ceilings yourself after the cause of the ceiling damage has been addressed. However, the repair can easily take 5 hours and can be slightly challenging for those without previous experience. If you do decide to flex your DIY muscle, have a helper to help hold the ladder and pass you the tools for safety purposes.

Costs range from $500 to $5,000, depending on damage size, labor, and finishing requirements.
