Drywall and plaster represent two fundamentally different wall finishing systems, each with distinct costs, longevity, and contractor requirements. Your choice affects not just the initial installation price but ongoing maintenance and repair expenses. Understanding the real numbers and what contractors actually charge helps you make an informed decision for your renovation.
Material Costs: Drywall vs. Plaster
Drywall (gypsum board) typically costs $10–$15 per sheet, with standard 4×8 sheets covering 32 square feet. A contractor installing drywall in a 500-square-foot room usually charges $1.50–$3.00 per square foot for labor and materials combined, putting the total around $750–$1,500 for that space.
Plaster runs significantly higher. Material costs alone range from $8–$20 per square yard, and skilled plaster contractors charge $5–$15 per square foot—sometimes more for decorative finishes. The same 500-square-foot room could cost $2,500–$7,500 in plaster work.
The primary reason: plaster requires multiple coats (typically three), specialized application techniques, and longer drying times between coats. Drywall is faster—one crew can hang and tape an entire room in 1–2 days, whereas plaster demands 3–5 days minimum.
Installation Timeline and Labor Considerations
Drywall contractors can move quickly because the process is standardized. After hanging sheets, they apply joint compound (mud) in three coats with sanding between each, finishing within a week for most residential projects. This speed translates to lower labor costs.
Plaster work demands experienced specialists. The first coat (scratch coat) must set properly before the second (brown coat) is applied, then a final finish coat goes on. Depending on humidity and plaster type, this can take 2–4 weeks. Fewer contractors offer plaster services compared to drywall, which often means higher rates due to limited availability.
If you need work completed quickly—say, before a move-in date—drywall contractors deliver. If you're restoring a historic home or want seamless, curved walls, plaster specialists become necessary despite the timeline.
Repair and Maintenance Costs
Drywall repairs are cheap and straightforward. A small hole costs $50–$150 to patch. Larger damaged sections run $200–$500 to replace. Most general contractors and handymen handle drywall repairs confidently.
Plaster repairs demand skill. Small cracks require specialized patching compound; larger repairs need a plaster contractor, costing $150–$400+ per repair. Plaster also cracks more easily in homes with foundation settling or high moisture.
Over 10 years, plaster maintenance often exceeds drywall significantly. Budget accordingly if you choose plaster, especially in older homes or moisture-prone areas.
Durability and Long-Term Value
Plaster lasts 50+ years when properly maintained. It resists impacts better than drywall and provides superior sound dampening. Historic plaster walls are still standing after a century.
Drywall typically lasts 15–30 years before needing replacement in high-traffic areas. It's more vulnerable to moisture, impacts, and settling. However, replacement is affordable, so the total cost-per-year often favors drywall in modern homes.
Finding and Hiring the Right Contractor
When comparing bids, drywall and plaster contractors operate differently:
- Drywall specialists focus on speed and consistency. Ask for references on flat finishes and how they handle transitions between rooms.
- Plaster contractors should show examples of ornamental work or repairs. Verify they've handled your specific plaster type (lime-based, gypsum-based, veneer plaster).
- General contractors typically subcontract plaster but handle drywall in-house, affecting pricing and timeline.
Request detailed quotes that specify material costs, labor rates (hourly or per square foot), and timeline. A reputable contractor explains why one system suits your project better.

Frequently Asked Questions
Q: Can I use drywall over existing plaster instead of removing it? Yes, hanging drywall over plaster works if the plaster is sound and not actively crumbling; it saves removal costs but adds height and may require adjusting door/window frames.
Q: How do I tell if a drywall contractor is experienced enough for a quality finish? Ask to see photos of high-quality finishes they've completed, request references from recent residential projects, and confirm they use premium joint compound and sanding techniques for smooth results.
Q: What's the best wall finish for a humid bathroom—drywall or plaster? Moisture-resistant drywall (greenboard or cement board) is the practical choice for bathrooms; plaster absorbs moisture and develops mold, making it unsuitable without extensive waterproofing.
