Attic insulation in Kure BeachCarolina Beach, on the ocean side of Pleasure Island, was incorporated in 1925 and spent its early decades as a summer resort. Hurricanes and a 1940 fire destroyed many of its early buildings, and most homes here were built in 1970 or later.
Carolina Beach, in New Hanover County, grew from 6,571 people in 2020 to 6,870 in 2025 (Census Bureau estimates), on 2.45 square miles. That makes Carolina Beach the second-largest town in New Hanover County.
Carolina Beach has about 6,300 housing units, 5 percent of New Hanover County's; 84 percent of the town's households own their home. Only about 3,100 of those 6,300 units were someone's usual home in the Census Bureau's 2020 to 2024 survey; the heating and owner figures on this page describe those 3,100.

The National Register nomination for the Joy Lee Apartment Building traces how slowly the town became a place to live all year. Storms, fires and a thin water supply kept it strictly a summer resort into the early 1920s. Even after a new well and a reservoir later that decade, only a few families stayed through the winter. Building picked up after a new highway and Snow's Cut arrived around 1930, and thirty new cottages went up in 1931 alone. A house that started out as a summer cottage was not necessarily built for winter use, and it may have grown in stages since. Look at every section of the attic before assuming anything, and make sure the bath, kitchen and dryer fans end outdoors.
On the night of September 19, 1940, a fire that started in the beach pavilion burned much of the business district. Concrete block then became the material of choice, the nomination explains, because it stood up to fire and wind and because wartime left other materials scarce. The Joy Lee itself went up in 1945 from blocks the owner's family pressed by hand, and its roof is flat and tar covered, hidden behind a parapet. A roof like that leaves little or no attic between it and the ceiling, so blown attic insulation is only an option where a real attic space can be reached. If you are not sure your house has one, say so when you call, because that is a house where a closer look comes first.
Some 17 percent of Carolina Beach's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
Built from 1970 to 1989, 40 percent of Carolina Beach homes may hold settled fiberglass; check its depth against the joists.
Carolina Beach's center sits near sea level, 7 miles from NOAA's Southport 5 N station, the best match for Carolina Beach. The station's 1991 to 2020 normals average about 2,200 heating and 2,230 cooling degree days a year, so Carolina Beach attics work in both seasons.
The state energy code marks New Hanover County warm and humid.
Some 42 percent of Carolina Beach housing units are detached single-family houses.
From 1990 to 2009, 27 percent of Carolina Beach homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
About 21 percent of Carolina Beach's housing units predate 1980; nearly all predate the state's 1978 insulation rule too. About 44 percent of Carolina Beach units sit in buildings of two or more homes, where the attic is often shared.
In Carolina Beach, 96 percent of households heat with electricity; where that heat is forced air, ducts often run through the attic.
Air sealing comes first, as the EPA advises: wire and pipe holes, wall tops and soffits.
Duke Energy Progress supplies Carolina Beach's electricity. For gas, Carolina Beach is in the New Hanover County franchise of Piedmont Natural Gas, whose mains may not reach every street in Carolina Beach. Duke's free House Call fits many Carolina Beach homes: 96 percent of households heat with electricity.

In a Carolina Beach attic, only wet, moldy or animal-soiled insulation is vacuumed out (ENERGY STAR's test), once the cause is fixed, and after mice that Carolina Beach attic is sanitized and deodorized; dry, clean insulation stays.

Attic insulation in Caswell BeachIt can let water in through a damaged roof, and the insulation soaks it up. The town has taken heavy blows before. The Joy Lee nomination records that Hurricane Hazel destroyed 362 buildings here in 1954, and that Diana in 1984 and Fran in 1996 each did widespread damage. Even that solid block building came through with some roof damage. ENERGY STAR reads soaked insulation as a sign that water is coming through the roof. The roof is fixed first, then we vacuum out the soggy insulation and replace it.
Not that the state's records show. The only National Register listing the State Historic Preservation Office places in Carolina Beach is the Joy Lee Apartment Building and Annex, a pair of postwar tourist apartments. Its list of local preservation commissions, dated 2023, shows three in New Hanover County, for Wilmington, Kure Beach and Wrightsville Beach, and none for this town. Being on the National Register would not tie an owner's hands anyway, the state office explains. Attic insulation here faces no historic review.
Carolina Beach Town Hall can say whether New Hanover County Permits & Inspections, the town itself or another office handles permits in Carolina Beach; ask before work starts.
