Whitsett Homes and Their Attics
Queen Anne Houses Around the Old Institute
The 1999 nomination says most of the district's houses were homes for the school's teachers, boarding houses or merchants' homes, and thirteen were built from 1900 to 1908. Several are Queen Anne houses whose hipped roofs are broken by cross gables, and the inventory records interior chimneys in several houses. A roof like that covers one main attic plus smaller pockets under each gable, some of them hard to reach. Each pocket gets the same even layer, with no thin spots. Any chimney rising through the ceiling first has its gap flashed with aluminum and sealed with heat-resistant caulk.
Attic Insulation in Whitsett
About 45 percent of Whitsett's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
Built from 1940 to 1969, about 35 percent of Whitsett homes often have little insulation.
The Local Climate
Whitsett's center sits about 680 feet above sea level, 7 miles from NOAA's Burlington Fire Station 5, the best match for Whitsett. The station's 1991 to 2020 normals average about 3,290 heating and 1,650 cooling degree days a year, so at Whitsett's station, heating needs outweigh cooling.

Whitsett Insulation FAQs
Does the Whitsett Historic District limit work on the attic?
The National Register listing does not. Holly Gate was listed on its own in 1980 and the district in 1999. The state preservation office says that kind of listing puts no strings on owners who keep up their own houses with their own money. The state's 2023 roster of preservation commissions lists none for Whitsett. Attic insulation is inside work. If outside changes such as new vents come up, ask the town, which has its own planning board.
Our Whitsett house once boarded students. Does the old wing have its own attic?
It can. The nomination describes one house of 1894 built with a wing just for students, and other family homes where students boarded. A wing under its own roof may hide a separate attic that is easy to miss, so we look for it. Houses of that age also come before 1930, the line ENERGY STAR draws for knob-and-tube wiring. Any such wiring is checked by an electrician before insulation goes near it.
Could the old insulation in a Whitsett attic be vermiculite?
It could: about 30 percent of Whitsett's homes predate 1960. If a Whitsett attic holds a pebble-like gray-brown or silver-gold fill, leave it undisturbed: the EPA says vermiculite may contain asbestos.
Does attic insulation in Whitsett need a permit?
Whitsett Town Hall can say whether Guilford County Inspections, the town itself or another office handles permits in Whitsett; ask before work starts.
