Imagine walking into your grandma’s old house, where the walls feel like part of the family history. Thick, textured plaster walls hold memories from decades past — but as cozy as they are, those walls have started to crack, crumble, and demand constant fixes.
Mark, a homeowner just like you, faced this dilemma when restoring his century-old Victorian. Should he keep battling those fragile plaster walls or switch to something modern like drywall?
If you’re wondering about drywall vs plaster, you’re not alone. It’s a decision many face when renovating or building, and it’s more than just picking materials — it’s about lifestyle, budget, and how much character you want your home to carry.
Let’s unpack the pros, cons, and costs of drywall and plaster so you can decide what fits your needs.
What Is Plaster? The Time-Tested Wall Finish
Plaster isn’t just any wall material — it’s a craft that has shaped homes for centuries. Traditionally, plaster consists of lime, cement, sand, and water applied in several layers onto wood laths or masonry. Once dried, it forms a solid, durable surface that can last for generations.
Why People Still Love Plaster
Plaster walls have a distinct look and feel. Their slight variations and subtle texture bring depth and warmth to a room. If you ever run your hand along a plaster wall, you’ll notice its density — it feels solid, unlike the thin, uniform surface of drywall.
Pros of Plaster
- Durability: When maintained properly, plaster walls can last a lifetime or longer. Unlike drywall, which can dent or puncture easily, plaster resists minor bumps and dings.
- Sound Insulation: Thanks to its thickness and density, plaster offers superior noise reduction. For anyone wanting quiet rooms away from street noise or noisy siblings, this is a major plus.
- Fire Resistance: Plaster is naturally fire-resistant. This means extra peace of mind, especially in older homes with wooden framing.
- Aesthetic Charm: Plaster brings a classic, vintage vibe. It’s the original “designer wall,” often featuring smooth or ornamental finishes that simply can’t be replicated with drywall.
Cons of Plaster
- Cracking: As houses settle or shift with time, plaster can develop hairline cracks. These aren’t just cosmetic; they often require specialized repair to prevent worsening damage.
- Labor-Intensive: Applying plaster takes skill and time. It involves multiple coats, drying periods, and careful finishing, which increases labor costs.
- Repair Complexity: Fixing plaster isn’t a quick DIY job. Matching the texture and color can be tricky, often requiring a professional’s touch.
- Weight: Because plaster is dense and thick, it adds significant weight to walls and the overall structure. This can be an issue in some renovations or additions.
What Is Drywall? The Modern Workhorse
Drywall, also known as gypsum board or sheetrock, is a panel made of gypsum plaster pressed between thick sheets of paper. Introduced in the mid-20th century, drywall revolutionized construction with its ease of use and affordability.
Why Drywall Took Over
Drywall’s popularity comes from its speed and cost-effectiveness. Instead of laborious hand-applied layers, drywall panels are hung quickly on framing and finished with joint tape and compound. The result? Walls go up faster, and repairs can often be done in the afternoon.
Pros of Drywall
- Cost-Effective: Drywall material and installation cost less than plaster, making it ideal for budget-conscious projects.
- Quick Installation: Hanging drywall panels is much faster than plastering walls, which is great when you want to move fast.
- Easy Repairs: Drywall repairs are straightforward. Holes can be patched or replaced with little fuss, often without professional help.
- Smooth Finish: Drywall offers a sleek, even surface perfect for painting or wallpapering.
- Versatility: Works well in nearly any building, compatible with insulation, vapor barriers, and modern framing techniques.
Cons of Drywall
- Less Durable: Drywall is prone to dents and holes, especially in busy homes with kids or pets.
- Moisture Sensitivity: Standard drywall can absorb moisture, leading to mold or deterioration in damp areas. Specialized moisture-resistant drywall exists but adds to costs.
- Soundproofing: Drywall alone doesn’t insulate sound as well as plaster, so additional insulation may be needed.
- Fire Resistance: Although drywall has fire-resistant properties due to gypsum, it generally doesn’t match plaster’s natural resistance.
While the pros and cons of drywall make it an easy choice, it’s not without trade-offs. But often, these trade-offs tilt in its favor for modern homes.

Breaking Down the Costs: What You Need to Know
When choosing between drywall and plaster, cost is often a dealbreaker.
Plaster Costs
Expect to pay around $3 to $8 per square foot installed. Why such a range? Plaster requires experienced artisans to apply several coats meticulously. In historic homes where walls need repair or patching, costs can rise further. Don’t forget to budget for maintenance — plaster cracks need timely repairs to avoid bigger problems.
Drywall Costs
Drywall installation is far more wallet-friendly, usually $1 to $3 per square foot. This includes hanging, taping, mudding, and sanding. Repairs are cheap and quick, perfect if you want to avoid ongoing expenses.
Repair Cost Comparison
- Plaster repairs: Can cost $300-$800 for moderate damage, due to the skill required.
- Drywall repairs: Often under $200 and sometimes a weekend DIY project.
Choosing Plaster: When Tradition Meets Functionality
Plaster suits homeowners who appreciate the historic or aesthetic value of their home. If you want authentic textures or are restoring a period property, plaster is hard to beat. Its sound insulation and fire resistance also appeal to those prioritizing safety and comfort.
That said, you should be ready for ongoing maintenance and occasional cracks as your home ages.
When Drywall Is the Smart Choice
Drywall is a no-brainer for new construction, budget renovations, or spaces where speed is essential. Its ease of repair means you don’t have to sweat small dings or holes. Plus, modern drywall types designed for moisture resistance make it usable in kitchens, bathrooms, and basements.
If you want clean, smooth walls that you can repaint or texture easily, drywall fits the bill.
The Value of Professional Drywall Services
You might be tempted to DIY drywall to save money, but professional drywall services bring expertise that’s hard to match:
- Flawless Finishing: Pros know how to tape and finish joints seamlessly.
- Faster Completion: A crew can handle large projects quickly, cutting your disruption time.
- Durability: Properly installed drywall lasts longer and resists wear better.
Hiring professionals can sometimes save money by preventing costly mistakes or rework down the line.
How Energy Efficiency Factors In
Walls aren’t just about looks—they affect how your home feels and how much energy it uses.
- Plaster’s thickness offers natural insulation and thermal mass, helping regulate temperature swings.
- Drywall is thinner but usually installed with insulation behind it, which can offer equal or better energy efficiency if done right.
Both can help keep heating and cooling costs down when paired with proper insulation.
Wrapping It Up
So, drywall vs plaster — which one wins? It depends on your home, budget, and preferences. Plaster offers historic charm, soundproofing, and durability but demands patience, skill, and money. Drywall is affordable, quick, easy to maintain, and works in almost any modern setting.
Ask yourself: How much character do you want? What’s your timeline and budget? How important is repair ease? Whatever your answer, knowing the pros, cons, and costs helps you make a smart choice.
