Sedalia Homes and Their Attics
Cottages Built for the School's Teachers
The 1988 nomination describes the school's buildings as mostly Colonial Revival and bungalow designs of the 1920s to the 1960s, one or two stories tall. Next to the campus, students built a one-and-a-half-story frame bungalow for the school's chaplain in 1926 and 1927. Brown's own cottage was given a steep hipped roof with shed dormers front and back and a one-story kitchen ell at the rear. Upstairs rooms under shed dormers end in short knee walls, and the low wedges of attic behind those walls leak air until someone seals and insulates them too. A rear ell under its own roof is opened and measured as a separate attic.
Attic Insulation in Sedalia
About 10 percent of Sedalia's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
The Local Climate

Sedalia Insulation FAQs
Does the Palmer Memorial Institute Historic District affect my Sedalia house?
Only if your house is one of the few inside it, and even then not for attic work. The district covers about sixty acres along a short stretch of US 70. It was listed in 1988, with more documentation added in 2022. The state preservation office says Register listing places no restriction on owners spending private money, and its 2023 roster names no commission for Sedalia.
What needs checking in a Sedalia house from the 1920s before it is insulated?
The wiring and the chimney. Any wiring put in during the 1920s is older than 1930, the year ENERGY STAR ties to knob-and-tube. Before insulation covers the ceiling, an electrician tells us whether any of it still carries power. If a brick chimney comes up through the attic floor, its gap gets aluminum flashing and high-heat caulk. Insulation then stays about 2 inches back from the brick, held off by a metal dam.
Does attic insulation in Sedalia need a permit?
Sedalia Town Hall can say whether Guilford County Inspections, the town itself or another office handles permits in Sedalia; ask before work starts.
