North Wilkesboro Homes and Their Attics
Queen Anne Houses on E Street
The town's first boom, in the 1890s and early 1900s, brought large frame houses two stories tall, with irregular plans, many gables, towers and sawn trim. A 2008 National Register nomination for one of them, built in 1893, singles out E Street for the finest houses left from those years. That house has interior brick chimneys and an unfinished attic under a roof of hips cut by gables. In the attic of a house like this, the open ring where each chimney comes up is bridged with aluminum flashing and heat-proof caulk. A short sheet-metal wall then keeps loose fill clear of the masonry. A roof of many gables also splits the attic into pockets, and each one is filled to an even depth.

The Local Climate

North Wilkesboro Insulation FAQs
Do the National Register listings in North Wilkesboro put rules on my attic?
No. The town's listings are the downtown Main Street district, the Southern Railway depot, Wilkes Hosiery Mills and one house of 1893. None of that ties your hands: the state preservation office notes that a listed owner paying their own way may maintain or change the property freely. The only Wilkes County commission on its 2023 roster belongs to Wilkesboro, across the river. So attic work needs no historic approval in this town.
Were the houses near the old Wilkes Hosiery Mills built as mill houses?
Not according to the mill's nomination. It places the mill at the edge of a middle-class neighborhood whose one- and two-story houses were mostly there before it. The present mill went up on that hillside from 1923 on. So treat them as houses of the town's early decades. If yours has a lower back wing under its own roof, that wing can hide a second, smaller attic, and it gets measured and filled separately from the main one.
Could the old insulation in a North Wilkesboro attic be vermiculite?
It could: about 45 percent of North Wilkesboro's homes predate 1960. If a North Wilkesboro 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 North Wilkesboro need a permit?
North Wilkesboro Town Hall can say whether Wilkes County Permit Information, the town itself or another office handles permits in North Wilkesboro; ask before work starts.
