Drywall vs Plaster: Which Is Right for Your East Texas Home?
Drywall and plaster are the two ways to finish an interior wall in residential construction. Drywall — gypsum board manufactured in 4x8 or 4x12 sheets — has been the residential standard since the 1950s. Traditional three-coat plaster over wood or metal lath was the standard before that and is still preferred for historic restoration and specialty modern installations. Each has trade-offs. Here is the full head-to-head for East Texas homeowners.
Cost
Drywall is dramatically cheaper. New-construction drywall in Longview runs $1.50 to $3.50 per square foot installed. Traditional three-coat plaster over lath runs $7 to $15 per square foot — 3-5x the cost. Even veneer plaster over blueboard (a faster modern hybrid) runs $4 to $7 per square foot. For pure cost, drywall wins handily.
Durability and Impact Resistance
Plaster wins. A 3/4-inch traditional plaster wall is significantly more impact-resistant than 1/2-inch drywall — door knobs, furniture moves, and kid impacts that dent drywall barely scratch plaster. Modern impact-resistant drywall closes the gap somewhat at a 25-40% material premium. For historic homes with original plaster, the existing walls are tougher than anything you'd put in to replace them.
Sound Performance
Plaster wins on mass alone — denser walls block more sound. A traditional plaster wall typically tests STC 38-42; a standard 1/2" single-layer drywall wall tests STC 33-35. However, modern drywall assemblies with resilient channels, sound insulation, and double layers can hit STC 55+, well beyond what unaided plaster delivers. For sound, the assembly matters more than the surface material.
Fire Rating
Both perform. 5/8" Type X drywall provides a tested, code-recognized 1-hour rating in standard assemblies. Plaster over metal lath provides excellent fire performance but isn't always part of pre-tested rated assemblies, which can complicate commercial inspections. For code-rated work, drywall is the easier path.
Repair
Drywall wins for ease of repair. A drywall patch can be invisible after texture match and paint. Plaster repair is artisan work — finding a plasterer who can match an existing veneer, much less original three-coat, is increasingly difficult in East Texas. We coordinate with a small network of plasterers when this is needed; most contractors can't help at all.
Climate Performance in East Texas
Plaster handles humidity better than standard drywall — gypsum mud cures and stays cured regardless of ambient RH, while drywall joint compound takes longer to dry in our humidity and can crack if rushed. Modern setting-type drywall mud (Easy Sand, Durabond) closes this gap completely. With proper materials, drywall performs perfectly well in Longview's climate.
Resale and Aesthetic Value
In pre-1940 historic homes (parts of Jefferson, Marshall, downtown Longview, Tyler's Azalea District), original plaster is a feature buyers actively value. Replacing plaster with drywall in a historic home can hurt resale. In every other home, drywall is the buyer expectation; plaster offers no resale premium and a noticeable cost premium.
Our Recommendation
Historic homes: preserve original plaster wherever it's sound; coordinate with a plasterer for repair. Modern construction: drywall is correct for cost, performance, and resale. Specialty applications (recording studios, high-end traditional architecture): plaster has a role. For the vast majority of Longview-area work — 95%+ of what we do — drywall is the right answer.
