New drywall installation costs 3 to 5 dollars per sqft including hang, tape, and texture. Small repairs cost 200 to 500 dollars. Large repairs (water damage, remodel patches) cost 500 to 2000 dollars per area.
Hang: 1/2-inch drywall for walls, 5/8-inch for ceilings (code requirement for fire rating). Green board for moisture-prone areas (not in direct water contact — use cement board for showers). Tape: 3 coats of joint compound on all seams and corners, sanded between coats. Texture: applied after taping. Prime after texture dries. $3-$5/sqft for hang + tape + texture.
Smooth (Level 5): no texture, just perfectly smooth joint compound skimmed over the entire surface. Premium look, highest cost ($1-$2/sqft extra). Popular in modern and contemporary homes. Orange peel: subtle bumpy texture sprayed on. The most common texture in 1980s-2000s LA homes. Knockdown: sprayed texture, then knocked flat with a wide blade. Medium texture, popular in traditional homes. Skip trowel: hand-applied, Mediterranean feel.
Small hole (under 6 inches): mesh patch + 2 coats of joint compound. $200-$400. Large hole (6-24 inches): cut back to studs, install new drywall piece, tape, texture match. $300-$600. Water damage: remove affected drywall, dry framing, install new drywall, match texture. $500-$2,000. Ceiling cracks: tape with mesh + compound, or skim-coat entire ceiling for persistent cracks. $500-$1,500.
The hardest part of drywall repair: matching the existing texture so the patch is invisible. Techniques: practice on cardboard, adjust sprayer nozzle and pressure, apply LESS texture initially (you can add more but can't remove). For orange peel: hopper gun with thin mud, medium pressure. For knockdown: hopper gun, wait 10-15 minutes, knock down with 12-inch blade. Even professionals need 2-3 attempts for perfect matches.
If your walls have: heavy orange peel texture you want to update to smooth, widespread cracking from settling, or multiple repair patches of different textures. Skim-coating: applying a thin layer of joint compound over the entire wall surface, then sanding smooth. Cost: $1.50-$3/sqft. It's the nuclear option but creates a flawless, modern smooth wall surface.
