About Trenton and Its Homes
Trenton, the Jones County seat on the Trent River, was laid out in 1784 around the courthouse site. Its historic district's 1974 nomination describes small frame buildings under moss-hung trees, and found most of the houses to be plain two-story frame homes with gable roofs and a center front gable.
Trenton, in Jones County, grew from 240 people in 2020 to 251 in 2025 (Census Bureau estimates), on 0.24 square miles.

Trenton Homes and Their Attics
Trenton Houses That Grew in Stages
The district's nomination found that buildings from the middle and late 1800s dominated the town, with a few earlier survivors, some hidden by later building. In many of the houses the center front gable was added to an older roof. One early house was probably built in several sections, and another gained a two-story wing later. A house put together over decades may have a separate attic tucked beneath every roof it gained, and the depth of insulation can differ from one to the next. So every one of those spaces is measured, and the insulation is spread evenly across all of them, with no thin low spots.
Attic Insulation in Trenton
About 60 percent of Trenton's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
The Local Climate
Trenton's center sits near sea level, 13 miles from NOAA's Richlands station, the best match for Trenton. The station's 1991 to 2020 normals average about 3,080 heating and 1,630 cooling degree days a year, so at Trenton's station, heating needs outweigh cooling.

Trenton Insulation FAQs
Does living inside the Trenton historic district change the rules for attic work?
Not by itself. National Register status came to the district in 1974, and the state preservation office says that status binds no private owner who uses personal funds to repair or remodel. Jones County is missing from the office's 2023 statewide list of local commissions. Attic sealing and insulation are indoor jobs in any case. If the work grows to include new roof or soffit vents, ask the town first in case local rules apply.
My old Trenton house has a brick chimney. How near it can insulation go?
That depends on where the chimney runs. One built against the outside of an end wall never passes through the attic floor. One that rises through the middle of the house does, like the interior chimney the nomination notes at the peak of a steep roof on Jones Street. There, ENERGY STAR calls for lightweight aluminum flashing over the ceiling gap, sealed with caulk made for high heat rather than foam. Then a short sheet-metal collar is fitted so the loose fill stays clear of the brick.
Could the old insulation in a Trenton attic be vermiculite?
It could: about 55 percent of Trenton's homes predate 1960. If a Trenton 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 Trenton need a permit?
Trenton Town Hall can say whether Jones County Inspections, the town itself or another office handles permits in Trenton; ask before work starts.
