New Orleans drywall guide covering shotgun houses, plaster-on-lath retrofits, Gulf humidity, hurricane water damage, and termite repairs. Practical DIY advice for Orleans Parish homeowners.
New Orleans is one of the more interesting cities to do drywall work in, and not always in a good way. The combination of historic housing, brutal humidity, and an active hurricane season produces drywall problems you do not see anywhere else. A 1910 shotgun in Bywater that was patched with drywall in the 1970s, hit by floodwater in 2005, partially repaired in 2007, and dealt with Hurricane Ida in 2021 is going to have layers of drywall history that take real detective work to understand.
The housing stock here is dominated by buildings that predate drywall by decades. Most homes in the historic core were built between 1840 and 1940 with plaster over wood lath on the interior walls. When those walls cracked or got water damaged, owners patched them with drywall starting in the 1950s and 60s, often badly, sometimes well. Today you find walls where the bottom four feet is modern half-inch drywall replacing a flood-damaged section, the top eight feet is original plaster with hairline cracks running through it, and somewhere in the middle is a transition joint that has been spackled fifteen times.
Humidity is the other defining feature. Summer dewpoints in New Orleans regularly hit 78°F. Indoor humidity in older homes without good HVAC can stay above 70 percent for weeks at a time, especially in houses built up off the ground where conditioned air does not reach the floor systems. Joint compound takes substantially longer to dry, paint takes longer to cure, and any leak or roof failure can start mold growth within 48 hours.
The neighborhoods all have their own character. The French Quarter has the oldest housing, much of it stucco over wood frame with very particular preservation rules. The Marigny and Bywater are dense with shotgun cottages and doubles, most needing constant patching. Uptown has larger homes with more interior plaster. Lakeview, Gentilly, and New Orleans East have more mid-century and post-Katrina construction with standard drywall throughout. The work you do in each of these areas is fundamentally different.
