Replacing plaster with drywall is a common remodeling project that affects walls, ceilings, and overall home feel. The cost depends on room size, material quality, removal effort, and labor rates. This guide presents typical price ranges, plus drivers and ways to save.
Assumptions: interior walls, standard 1/2-inch drywall, no plumbing or electrical rerouting, typical ceiling height, urban or suburban market.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Total project price | $2,000 | $4,000 | $8,000 | Includes removal, installation, finish, and paint on typical rooms |
| Per-square-foot price | $3 | $5 | $7 | Assumes standard ceilings and no custom textures |
| Per-room price (average-size) | $3,000 | $5,000 | $7,500 | Depends on room dimensions and finishes |
| Labor component | $1,500 | $3,000 | $6,000 | Includes framing, hanging, taping, mudding, sanding |
| Materials (drywall, tape, mud) | $600 | $1,500 | $2,500 | Premium materials raise the high end |
Typical Cost Range
Cost range overview: Replacing plaster with drywall typically runs from $2,000 to $8,000 for interior walls in a standard home, with most projects landing around $4,000-$5,500. Per-square-foot pricing generally falls in the $3-$7 range, depending on ceiling height, removal difficulty, and finish quality. Factors like decorative plaster restoration, acoustic treatments, or moisture-prone areas can push costs higher.
Project scope and room count influence totals more than a single factor. A small bathroom may stay near the lower end if framed surfaces are straightforward, while a large living area with vaulted ceilings and numerous openings can push toward the higher end.
Cost Breakdown
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $600 | $1,400 | $2,600 | Drywall sheets, joint compound, tape, screws, corner beads |
| Labor | $1,500 | $3,000 | $6,000 | Framing, hanging, taping, mudding, sanding, priming |
| Equipment | $100 | $400 | $1,000 | Removed debris tools, lifts, dust containment |
| Permits | $0 | $50 | $300 | Typically not required for interior drywall work; check local rules |
| Delivery/Disposal | $50 | $250 | $800 | Waste hauling and disposal fees |
| Contingency | $150 | $500 | $1,000 | Unforeseen framing or wiring adjustments |
What Drives Price
Labor rate and crew size significantly affect totals. A two-person crew may complete basics faster but costs more per hour than a single carpenter. Regional wage differences influence hourly rates and travel fees.
Ceiling height and room geometry impact material waste and time. Vaulted ceilings, irregular walls, or numerous openings increase finishing hours and equipment usage. Seams and texture preferences also alter labor intensity.

Existing plaster condition affects removal effort. Solid plaster with lath requires more demolition and disposal than lightweight scratch coats, which shifts the project budget upward.
Ways To Save
Plan room-by-room for cost control by batching demolition, install, and finishing in phases, reducing labor downtime and equipment rental needs.
Choose standard finishes over specialty textures or decorative plaster remakes; opting for flat primer and paint lowers labor and material costs.
Obtain multiple bids from licensed drywall contractors to compare pricing for the same scope. Ask for itemized quotes to identify price drivers and negotiate bundled services.
Regional Price Differences
Prices vary across regions due to labor markets, material availability, and local codes. In the Northeast, expect higher labor wages and overhead, while the South may be more moderate. The West often reflects higher material costs in urban areas.
Annual price shifts can occur with supply chain dynamics or seasonal demand, with spring and summer typically busier for remodeling work, potentially raising quotes by 5–15% during peak times.
Labor & Installation Time
Typical installation time for a standard room ranges from 1.5 to 3.5 days for a two-person crew, depending on wall count and finishes. Drying and painting add additional days in the project timeline. Always account for weather and site accessibility when scheduling.

Additional & Hidden Costs
Hidden costs to consider include debris disposal, scaffolding or lifts for high ceilings, and temporary protection for flooring and furnishings. If plumbing or electrical changes are discovered, expect additional permits and labor costs.
Moisture-prone areas such as bathrooms or basements may require moisture-resistant gypsum boards and upgraded waterproofing, increasing both materials and labor.
Real-World Pricing Examples
Three scenario cards illustrate typical budgets across common situations.
Basic: 250 sq ft living room on standard ceiling — 2-person crew, standard drywall, flat finish. Materials: $600; Labor: $1,900; Equipment/Disposal: $300; Total: around $2,800.
