Walnut Cove Homes and Their Attics
Paired Inside Chimneys After About 1900
The 1989 Stokes County survey found that around 1900 builders across the county began moving chimneys off the outside gable ends and into a pair near the middle of the house. One example the survey found in town, a two-story frame house from about 1910 with a steep hipped roof, has interior chimneys. A chimney placed inside the house climbs straight up through the attic floor, and the opening left around the brick is a wide path for heated air. We close that ring with thin aluminum flashing and heat-rated caulk, never foam, and fit a sheet-metal dam around the stack so loose fill stays clear. ENERGY STAR says codes generally call for 2 inches between insulation and masonry.
Attic Insulation in Walnut Cove
About 40 percent of Walnut Cove's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
Built from 1970 to 1989, about 40 percent of Walnut Cove homes may hold settled fiberglass; check its depth against the joists.
The Local Climate
Walnut Cove's center sits about 660 feet above sea level, 10 miles from NOAA's Rural Hall station, the best match for Walnut Cove, though not a close one. The station's 1991 to 2020 normals average about 3,960 heating and 1,220 cooling degree days a year, so at Walnut Cove's station, heating needs outweigh cooling.
Walnut Cove sits about 300 feet below the station, so expect slightly milder winters.

Walnut Cove Insulation FAQs
Is the old center of Walnut Cove a protected historic district?
No. The town has no National Register district. Its two listings are single buildings: Christ Episcopal Church on Summit Avenue, and the former Walnut Cove Colored School, the only Rosenwald school built in Stokes County. Neither listing reaches the houses nearby. The state preservation office's commission list, dated 2023, shows nothing for Stokes County, so attic work here needs no sign-off from any historic board.
What if my old Walnut Cove attic has gray or gold pebbles instead of fluffy insulation?
Leave it where it is until it has been tested. That look fits vermiculite, and the EPA says a Libby, Montana mine with an asbestos deposit supplied most of the vermiculite sold in the country from 1919 to 1990. The town's railroad-era houses stood through all of those decades. The EPA's advice is to keep the material undisturbed, keep boxes out of that attic, and call an asbestos contractor. We do not take out or cover vermiculite.
Does attic insulation in Walnut Cove need a permit?
Walnut Cove Town Hall can say whether Stokes County Planning & Inspections, the town itself or another office handles permits in Walnut Cove; ask before work starts.
