Greenville's mix of historic and new-construction homes means many of our customers are weighing plaster repair against full drywall replacement. This comparison breaks down both materials across every dimension that matters: cost, durability, sound, fire rating, repairability, and resale impact.
MATERIAL & CONSTRUCTION. Plaster is a 3- or 4-coat wet system over wood or gypsum lath, totaling 3/4" to 1" thick. Drywall is factory-made gypsum panels 1/2" or 5/8" thick, screwed to studs and finished on-site with tape and joint compound. Plaster takes weeks to install and cure; drywall takes days.
COST. New drywall in Greenville runs $1.50–$3.00 per square foot installed. New plaster, where you can still find a skilled plasterer, runs $7–$12 per square foot. Repair pricing follows the same ratio — a wall patch in plaster costs roughly 2–3x what the same patch costs in drywall, because of the slower three-coat process and the skill required to match texture.
DURABILITY. Plaster wins on hardness — it resists dings and impacts that would dent drywall. But plaster is brittle and cracks along stress lines as a house settles. Drywall is softer but more forgiving of movement; small cracks can be patched and re-feathered easily.
SOUND & FIRE. Plaster's mass makes it noticeably quieter than standard 1/2" drywall, with about a 5–7 STC advantage in typical wall assemblies. Fire-wise, plaster is naturally fire-resistant; drywall achieves the same rating with 5/8" Type X board. Modern soundproofing assemblies using Green Glue or QuietRock can match or exceed plaster's acoustic performance.
REPAIRABILITY. This is where drywall pulls dramatically ahead. A skilled Greenville drywall pro can patch a fist-sized hole in an afternoon — invisibly. Plaster repair requires a specialist, takes multiple days for setting compound to cure between coats, and is genuinely difficult to match texture-perfect. We can do it, but it's a different skill set than drywall.
RESALE IMPACT. For homes built before 1955 with intact plaster, careful repair adds character value — Greenville buyers in historic districts often pay a premium for genuine plaster walls. For mid-century and newer homes, drywall is the expected standard and there's no resale penalty for replacing failing plaster with quality drywall. Mixing the two in the same home is fine if transitions are well-finished.
OUR RECOMMENDATION. If your Greenville home is pre-1955 with mostly-intact plaster, repair and preserve it where possible — it's part of the home's value. If plaster has detached or is failing in large sections, full drywall replacement with proper texture matching is usually more cost-effective long-term. We do both.
