Drywall Installation

Hang sequence starts with ceilings, then walls top-to-bottom with butt joints staggered. Fastener spacing per GA-216 — 16" OC on ceilings, 16"–24" OC on walls. All joints taped with paper tape (not mesh on butt joints) bedded in setting-type mud. Three coats minimum, sanded between coats. Primer is shellac-based for any smoke- or water-stained substrate and PVA elsewhere. Texture is applied with calibrated hopper or air-driven gun — we test on cardboard against your existing wall sample to dial in match before spraying. Single-room scope: 3–5 days. Whole-home or full reconstruction: 2–4 weeks.

Texture mismatch is the #1 failure on amateur work — raking light from low-angle Arizona afternoon sun makes every imperfect patch visible. Nail and screw pops are common on 1990s–2000s tract homes from seasonal humidity swings; we re-secure and refinish. Water-stained ceilings from monsoon leaks or upstairs bathroom failures need full-sheet replacement once paper face is compromised — surface paint over a wet stain re-bleeds within weeks. Bathroom drywall around showers should be moisture-resistant board (purple board), not standard sheetrock; replacing with the right material prevents future mold.

Installation per GA-216 (Gypsum Association Application & Finishing). Sheet sizes: 1/2" regular for walls, 5/8" Type X for ceilings and garage walls per IRC fire requirements. Joint compound: setting-type for first two coats, lightweight all-purpose for finish coat. Tape: paper for tapered joints, fiberglass mesh only on small patches. Finish levels per GA-214 — Level 4 standard, Level 5 skim coat for areas with critical light or semi-gloss/gloss paint. All work warrantied under ROC #349454.
