Finishing a Basement in Rock Hill: The Drywall Guide

Finished basements are one of the highest-value remodels in the Rock Hill market — usable square footage at roughly half the cost of an above-grade addition. But basement drywall is genuinely different from above-grade drywall: moisture is harder to manage, fire-rated assemblies are often required, ceiling height is tighter, and consequences of the wrong board are bigger. Here is the contractor-level guide.

Specify the right board everywhere

Standard half-inch paper-faced drywall has no business on a Rock Hill basement wall. We specify mold-resistant board (purple or green) on every below-grade wall, every ceiling, and every wall within four feet of a mechanical room. For utility rooms with furnaces or water heaters, fire-rated 5/8-inch Type X is typically required by code.

Vapor and moisture management before drywall

Drywall is the last step, not the first defense. Before we hang anything, we verify the foundation is sealed, exterior moisture issues are addressed, framing is dry, and the room has a plan for active humidity control (typically a dedicated dehumidifier sized to the space). Skipping these guarantees a callback.

Ceiling height and finish level

Most Rock Hill basements have ceilings between 7'6" and 8'4" — tight enough that texture choices matter. We almost always recommend a Level 4 smooth finish. It makes low ceilings feel taller and reflects more light. Popcorn or knockdown texture is a bad call in a basement.

Typical Rock Hill basement pricing

A 1,200 sq ft finished basement runs $4,500 to $9,000 for drywall scope in 2026 — depending on ceiling height, room count, fire-rated assemblies, and finish level. That typically covers mold-resistant board on all surfaces, fire-rated board in mechanical areas, Level 4 finish, prime-ready surface, and our 10-year warranty.

Coordination with other trades

Basement drywall has to be coordinated with framing, electrical, plumbing, HVAC, and (if applicable) egress window installation. We sequence carefully with the GC or other subs. Rough inspections happen before any drywall is hung.

Finished basement timeline

A typical 1,200 sq ft basement takes our crew 7 to 12 working days from hang start to final sand, spread across two and a half to three weeks calendar time (accounting for mud dry days, sub coordination, and inspections). Larger basements extend proportionally.
