About Spring Lake and Its Homes
Spring Lake grew up on the edge of Fort Bragg, with its first buildings on Main Street in 1920 and houses built to rent or sell along Spring and Lake Avenues from 1933. It was incorporated in 1951, after plans were made to hand the town the water and sewer system the federal government ran during the war.
Spring Lake, in Cumberland County, fell from 11,517 people in 2020 to 11,252 in 2025 (Census Bureau estimates), on 23.6 square miles. That makes Spring Lake the third-largest town in Cumberland County.
Spring Lake has about 5,400 housing units, 4 percent of Cumberland County's; 20 percent of the town's households own their home. About 4,500 of those 5,400 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 4,500.

Spring Lake Homes and Their Attics
Sandhills Ground and the Postwar Subdivisions
Spring Lake sits in the Sandhills, the sandy belt between the Piedmont and the Coastal Plain that takes in the northwest part of Cumberland County. After 1951 the town kept filling with military families, and farms were sold off for houses. Holly Hills, laid out on a family farm off North Bragg Boulevard in the 1950s, was the first planned subdivision. Building America's guide finds that a radiant barrier earns its keep where an attic has little insulation and the ductwork runs through it, since the foil keeps those ducts cooler in summer. Laid over a thick blanket of insulation, the same foil changes little.
Attic Insulation in Spring Lake
Some 22 percent of Spring Lake's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
From 1990 to 2009, 36 percent of Spring Lake homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
The Local Climate
Spring Lake's center sits about 280 feet above sea level, 10 miles from NOAA's Fayetteville PWC station, the best match for Spring Lake. The station's 1991 to 2020 normals average about 2,970 heating and 1,890 cooling degree days a year, so at Spring Lake's station, heating needs outweigh cooling.
Spring Lake sits about 200 feet above the station, so expect slightly colder winters.
Homes by Age: What It Means for the Attic
Some 40 percent of Spring Lake housing units are detached single-family houses.
Built from 1970 to 1989, 28 percent of Spring Lake homes may hold settled fiberglass; check its depth against the joists.
About 36 percent of Spring Lake's housing units predate 1980; nearly all predate the state's 1978 insulation rule too. Some 48 percent of Spring Lake units sit in buildings of two or more homes, where the attic is often shared. Renters hold 80 percent of Spring Lake's occupied homes, so many attic decisions rest with landlords.

Spring Lake Insulation FAQs
Is anything in Spring Lake on the National Register, and could it affect my house?
Nothing inside the town limits is listed on the state's register list. The state did judge the old town school on South Third Street eligible in 2007. Long Valley Farm is listed, but its nomination places it in the Spring Lake vicinity, outside the town, and the Pope Air Force Base district lies on the post. The 2023 state list of preservation commissions gives Cumberland County only Fayetteville's. So no historic review stands between your house and attic work.
I own a rental near the base in Spring Lake. Who decides about the attic?
You do, as the owner. Spring Lake began in the years after World War I partly as a place for service members to live near the post. The stretch between one tenant and the next is the easy time. With someone living there, pick a day together and clear a path to the attic hatch. We work from the attic itself, sealing the gaps in the ceiling before the insulation goes down.
Does attic insulation in Spring Lake need a permit?
Spring Lake Town Hall can say whether Cumberland County Building Inspections & Permitting, the town itself or another office handles permits in Spring Lake; ask before work starts.
