About Gibsonville and Its Homes
Gibsonville was laid out around a railroad depot astride the Guilford-Alamance county line and chartered in 1871, then grew with the Minneola cotton mill. The bulk of the town's houses are from 1970 or later, yet the older streets near the tracks hold mill housing and big frame houses from its boom years.
Gibsonville, in Guilford County, grew from 9,149 people in 2020 to 9,876 in 2025 (Census Bureau estimates), on 4.37 square miles. That makes Gibsonville the fourth-largest town in Guilford County.
Gibsonville has about 4,000 housing units; about 81 percent of the town's households own their home.

Gibsonville Homes and Their Attics
What Remains of the Minneola Mill Village
The Minneola company began adding worker houses around 1903, after the Cone family bought the mill. It kept mill housing in three places. Seven houses beside the mill were gone before 1924, and the village south of it, about sixty dwellings, came down between 1955 and 1967. Some were moved rather than torn down: thirteen of the twenty-seven new houses the town approved in 1953 were relocated mill houses being fixed up. The mill's 2023 nomination says the only mill housing left stands along Whitsett Avenue and South Joyner Street. Houses wired in those early decades get an electrician's look first, since ENERGY STAR calls knob-and-tube wiring from before 1930 a fire hazard where insulation touches it.
Big Frame Houses From the 1890 to 1910 Boom
One National Register nomination dates Gibsonville's main growth to 1890 through 1910, after the mill opened. The house it records, from 1898, is a two-and-a-half-story frame Queen Anne and Colonial Revival design under a high hipped roof. Gables face all four ways, and two tall chimneys rise through it. A roof with that many gables can split the attic into separate pockets, and each one is reached and filled to an even depth, with no low spots left behind. Every chimney gap gets aluminum flashing and heat-rated caulk, and a metal dam holds the insulation off the brick.
Attic Insulation in Gibsonville
Some 11 percent of Gibsonville's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
In 2010 or later, about 40 percent of Gibsonville homes went up; check their air sealing as well as the depth.
The Local Climate
Gibsonville's center sits about 720 feet above sea level, 6 miles from NOAA's Burlington Fire Station 5, the best match for Gibsonville. The station's 1991 to 2020 normals average about 3,290 heating and 1,650 cooling degree days a year, so at Gibsonville's station, heating needs outweigh cooling.
Homes by Age: What It Means for the Attic
Some 86 percent of Gibsonville housing units are detached single-family houses.
From 1990 to 2009, about 30 percent of Gibsonville homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
About 20 percent of Gibsonville's housing units predate 1980; nearly all predate the state's 1978 insulation rule too.

Gibsonville Insulation FAQs
Are there historic district rules for older houses in Gibsonville?
No district rules, as far as the state's lists show. Gibsonville's National Register entries are single properties: one house, the old school, and the Minneola mill and its cloth warehouse. The state's 2023 roll of local commissions lists Greensboro, High Point and Oak Ridge in the county, but not Gibsonville. Per the state preservation office, being listed does not restrict an owner who maintains or alters a house with private money. If you are unsure whether a house is a designated county landmark, Guilford County's joint commission can tell you.
Did the mill company put insulation in the old Minneola mill houses?
Nothing obliged it to. The village went up in the mill's early decades, and the state's insulation requirement for new houses reaches only those begun from 1978 on. Many of these houses also changed hands and places in the 1950s, when the company cleared the southern village. The nomination says nothing about insulation either way. We measure it in several spots and look over the wiring and any chimney before adding to it.
Does attic insulation in Gibsonville need a permit?
Gibsonville Town Hall can say whether Guilford County Inspections, the town itself or another office handles permits in Gibsonville; ask before work starts.
