The age of your home can clue you in to whether you have plaster or drywall ceilings. Homes built after the ‘70s are more likely to have drywall ceilings and walls, while older homes have plaster. You can also do the pushpin test: A pushpin will go into drywall, whereas it’s much harder to push one into a plaster wall. If you’re still unsure, ask a drywall professional to let you know which type of ceilings and walls you have.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

In most cases, no, you won’t need a permit to replace drywall. If you’re changing the floorplan of your home by adding or removing walls during the drywall project, then you might need a permit, but replacement or repairs usually doesn’t require a permit. Your drywall professional should be able to confirm whether or not a permit is required for your project. If it is, it’s likely to add between $50 and $150 to your total cost. Keep in mind that you will need permits if you plan to install new electrical wiring or plumbing lines behind your new drywall.

Both plaster and drywall are durable wall finishes, but they differ significantly in installation, cost, performance, and aesthetics.

Installation & Cost: Drywall installation is faster and more affordable, typically costing $1.50 to $3 per square foot. It uses premade sheets, making it a more accessible DIY project. Plastering is a labor-intensive craft that requires specialized skills, pushing costs to $2 to $10 per square foot. It involves applying a wet paste over a lath framework.

Durability & Performance: Plaster is generally more durable, longer-lasting, and provides superior soundproofing. It is also a better insulator, which can help reduce energy costs. Drywall is easier to remove for future renovations.

Aesthetics: Drywall provides a smooth, uniform surface ready for paint or texture. Plaster offers a high-end, naturally textured look that can hide imperfections and is often preferred for achieving a classic or historic aesthetic.

Which is better? The choice depends on your priorities. Drywall is ideal for those prioritizing a lower upfront cost, faster installation, and DIY potential. Plaster is the better option for a higher-end project where durability, soundproofing, and a unique, premium finish are more important than the initial cost.
