About Newton Grove and Its Homes
Newton Grove grew up in the early 1800s where the Raleigh to Wilmington road crossed the Fayetteville to Tarboro stage road. It took its post office name in 1849 and was incorporated in 1879 and again in 1935, yet the published record says next to nothing about the houses in town.
Newton Grove, in Sampson County, grew from 582 people in 2020 to 600 in 2025 (Census Bureau estimates), on 3.08 square miles. That makes Newton Grove the fourth-largest town in Sampson County.
Newton Grove has about 295 housing units, 1 percent of Sampson County's.

Newton Grove Insulation FAQs
Is my Newton Grove house listed as a historic property?
Not if it sits inside the town limits. Thirteen Oaks, the Isaac Williams House and every other National Register listing with the Newton Grove name sit beyond the town limits. The state files them under the vicinity. In Sampson County the only local preservation commission on the 2023 state directory is Clinton's. No outside review applies to attic work in town, only the checks a house of its age calls for.
What sort of attic does an old Sampson County farmhouse near Newton Grove have?
A narrow one over the main block, since the house is one room deep, and a low one, if any, over the back rooms. The county's 1986 Multiple Resource Nomination calls the two-story, one-room-deep I-house its standard house from about 1830 until past 1910, first with shed rooms across the rear and later an ell. A shed roof slopes low toward the back wall. ENERGY STAR warns that an attic's middle can be well covered while its edges get very little, so we work insulation out to the eaves and keep baffles at the soffit vents.
Could the old insulation in a Newton Grove attic be vermiculite?
It could: about 25 percent of Newton Grove's homes predate 1960. If a Newton Grove 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 Newton Grove need a permit?
Newton Grove Town Hall can say whether Sampson County Building Inspections, the town itself or another office handles permits in Newton Grove; ask before work starts.
