The Postwar Drywall Revolution in Pittsburgh Homes
The postwar drywall revolution transformed American home building after World War II. Learn how wartime shortages drove drywall adoption in Pittsburgh homes.
Wartime Material Shortages
World War II created severe shortages of labor and materials that forced the American construction industry to adopt faster, more efficient building methods, accelerating the transition from traditional wet plaster to drywall that would permanently reshape residential construction in the United States. During the war years from 1941 to 1945, millions of skilled construction workers, including experienced plasterers, were drafted into military service or drawn to higher-paying defense industry jobs, creating an acute shortage of the trained labor needed to apply traditional three-coat plaster in the millions of housing units that the government was building to house defense workers near military bases and war production facilities. Simultaneously, many of the raw materials used in traditional plastering, including the metal components of expanded metal lath, were restricted or rationed for military use, making conventional plaster application difficult even when skilled labor was available. These twin pressures of labor shortage and material restrictions created unprecedented demand for alternative wall finishing methods that required fewer skilled workers and less restricted materials. Gypsum wallboard, which could be installed by workers with minimal plastering training using only nails, a hammer, and basic finishing supplies, offered an obvious solution. The federal government actively promoted drywall use in defense housing projects, and the massive scale of wartime construction exposed thousands of builders and workers to drywall installation methods for the first time. By the end of the war, the construction industry had gained extensive practical experience with drywall, and an entire generation of workers had learned to install and finish the product, creating the workforce that would drive drywall's dominance in the postwar building boom.
Levittown and Mass Production
The postwar housing crisis that followed World War II created demand for new homes on a scale never before seen in American history, and the innovative mass-production building methods developed by companies like Levitt and Sons demonstrated conclusively that drywall was the wall finishing system best suited to high-volume, cost-efficient residential construction. When millions of returning veterans and their growing families needed affordable housing simultaneously, the traditional model of custom-building individual homes using skilled craft labor could not possibly meet the demand at prices that young families could afford. William Levitt and other pioneering merchant builders solved this problem by applying assembly-line principles to home construction, breaking the building process into specialized tasks performed by dedicated crews who moved systematically from house to house. In this system, drywall's advantages over traditional plaster were overwhelming. A drywall crew could hang and finish the walls and ceilings of a complete house in a fraction of the time required for three-coat plaster application, with less skilled labor, lower material costs, and no need to wait days between coats for drying and curing. The Levittown developments on Long Island, in Pennsylvania, and in New Jersey demonstrated that drywall could be installed at speeds and costs that made affordable mass-produced housing economically viable, and builders across the country quickly adopted the same methods. The success of mass-produced housing established drywall as the default wall finishing material for new residential construction and created enormous demand for drywall products and trained installers that has continued to grow for more than seventy years.
Postwar Drywall in Pittsburgh
Pittsburgh's postwar experience with drywall adoption reflected both the national trends that drove the material's dominance and local factors unique to the city's construction industry, housing market, and labor traditions that shaped how and where drywall replaced traditional plaster in the region's residential building stock. The immediate postwar period saw rapid suburban development in communities surrounding Pittsburgh, including Penn Hills, Monroeville, Bethel Park, and Upper St. Clair, where new subdivisions built to house the expanding middle class used drywall almost exclusively because it enabled the construction speed and cost efficiency that competitive housing markets demanded. Within the city limits, however, the transition was more gradual. Pittsburgh's strong plasterers' unions resisted the displacement of their trade, and the city's older, established neighborhoods were dominated by existing homes with traditional plaster rather than new construction. Renovation and repair work in these older neighborhoods often involved patching and restoring existing plaster rather than replacing it with drywall, maintaining demand for traditional plastering skills even as new construction shifted entirely to drywall. The result is a metropolitan housing stock that spans the full spectrum of wall construction, from pristine original three-coat plaster in well-maintained Victorian and Edwardian homes to mid-century drywall installations in suburban ranch houses to modern drywall in contemporary construction and renovations. This diversity makes Pittsburgh's drywall and plaster repair market uniquely demanding, requiring contractors who understand both traditional plaster systems and modern drywall methods.
