About Teachey and Its Homes
Teachey grew from Teachey's Depot on the Wilmington and Weldon Railroad, was incorporated in 1874, lost its charter in 1897 and was chartered again in 1903. The county's 1994 study found early 1900s stores here, a frame lodge beside the tracks and a turreted house from the late 1800s.
Teachey, in Duplin County, grew from 475 people in 2020 to 500 in 2025 (Census Bureau estimates), on 1.05 square miles.
Teachey has about 225 housing units, 1 percent of Duplin County's; about 69 percent of the town's households own their home.

Attic Insulation in Teachey
About 25 percent of Teachey's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
Built from 1970 to 1989, about 30 percent of Teachey homes may hold settled fiberglass; check its depth against the joists.
The Local Climate
Teachey's center sits about 70 feet above sea level, 3 miles from NOAA's Wallace 1 SE station, the best match for Teachey. The station's 1991 to 2020 normals average about 2,900 heating and 1,850 cooling degree days a year, so at Teachey's station, heating needs outweigh cooling.

Teachey Insulation FAQs
Is the old part of town a registered historic district?
No. The 1994 county study named a Teachey Historic District to the state's study list, which is kept apart from the National Register. Not one property within town limits made the state's Register listings. Duplin's one local commission on the 2023 state directory is Warsaw's. So a homeowner here faces no historic review for attic work.
My Teachey house has a turret and a back wing. Is that more than one attic?
It can be. The county study names a late 1800s house here as one of only two in Duplin with a turret. It also says a rear ell usually sat behind the county's one-story houses of the early twentieth century. A turret, a wing or an ell each sits under its own piece of roof, and each piece can close over its own small attic. We open up every one we can reach. ENERGY STAR asks for insulation spread evenly, and a wing nobody looked into is the thinnest spot in the house.
Does attic insulation in Teachey need a permit?
Teachey Town Hall can say whether Duplin County Building Inspections, the town itself or another office handles permits in Teachey; ask before work starts.
