Drywall vs. Plaster (2026): Cost, Durability & Which to Choose

The short answer

• Keep plaster that's in good shape — repair costs less than demolition plus new drywall and preserves value in historic neighborhoods. Switch to drywall when walls must come open anyway (rewiring, insulation, plumbing) or when plaster is failing across large areas. Many DMV rowhome renovations sensibly end up hybrid: plaster preserved in front rooms, drywall in kitchens, baths, and basements.

Drywall — $1.50 – $3.50 per sq ft installed and finished (DMV); lifespan 50+ years if kept dry

• Pro: Cheapest wall system to install and to repair
• Pro: Fast: rooms hung and finished in days, not weeks
• Pro: Every contractor can work on it — competitive bids
• Pro: Easy access for wiring, plumbing, and insulation upgrades
• Con: Thinner sound and fire performance than traditional plaster at standard thickness
• Con: Softer surface — dents and scuffs more easily
• Con: Flat, modern look can feel wrong in a historic home
• Best for: Renovations, additions, basements, budget-conscious repairs, and any wall you plan to open again.

Plaster — $5 – $10+ per sq ft for new veneer plaster; skilled repair work bills at premium hourly rates (DMV); lifespan 75 – 100+ years when maintained

• Pro: Harder, denser surface with better soundproofing
• Pro: Historic character — curved walls, ornate moldings, authentic texture
• Pro: More fire-resistant per inch than standard drywall
• Pro: Sound existing plaster can often be repaired rather than replaced
• Con: Two to four times the cost of drywall
• Con: Skilled plasterers are scarce in the DMV — fewer, higher bids
• Con: Cracks with house settling and is slow to repair
• Con: Demolition is heavy, dusty work (often with lead paint on top in pre-1978 homes)
• Best for: Historic restorations, rooms where existing plaster is mostly sound, and owners who value original character.

Common questions

Should I replace plaster with drywall?

Only when the wall has to come open anyway or the plaster is failing across large areas. Sound plaster is worth keeping: repair is cheaper than demolition plus new drywall, and original plaster adds character and value in DC-area historic districts.

Is plaster more expensive than drywall?

Yes — new veneer plaster runs roughly two to four times the installed cost of drywall in the DMV, and skilled plaster repair bills at premium rates because the trade is scarce.

Can you patch plaster with drywall?

Yes. Cutting out damaged plaster sections and infilling with drywall shimmed flush, then skim-coating the joint, is the standard budget repair — most homeowners can't spot a well-done hybrid patch.
