About Claremont and Its Homes
Claremont, in northeastern Catawba County, was known first as Charlotte Crossing and then as Setzer's Depot before it took its present name in 1892 and was incorporated a year later. Historians have written little about its houses, so each attic is judged by the house around it.
Claremont, in Catawba County, grew from 1,696 people in 2020 to 1,790 in 2025 (Census Bureau estimates), on 2.86 square miles.
Claremont has about 850 housing units, 1 percent of Catawba County's.

Attic Insulation in Claremont
Some 23 percent of Claremont's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
From 1990 to 2009, 32 percent of Claremont homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
The Local Climate
Claremont's center sits about 980 feet above sea level, 5 miles from NOAA's Catawba 5 SW station, the best match for Claremont. The station's 1991 to 2020 normals average about 3,300 heating and 1,560 cooling degree days a year, so at Claremont's station, heating needs outweigh cooling.
Readings change over short distances around Claremont: NOAA's Hickory Airport station, 13 miles away, averages about 3,550 heating degree days. NOAA estimated part of the Catawba 5 SW station's normals from nearby stations, so treat them as approximate.

Claremont Insulation FAQs
Is anything in Claremont on the National Register?
Nothing inside the town limits. The state's register list places two Catawba County properties just outside town, the Bunker Hill Covered Bridge and Rock Barn Farm. Hickory has the county's only local preservation commission on the state's 2023 roster. So a house within the town needs no historic review before attic insulation or air sealing.
A metal flue pipe runs up through my Claremont attic. How is it handled?
With metal and heat-rated caulk, never foam or loose insulation against the pipe. Going by the Census numbers elsewhere on this page, most homes in town date from 1970 on. A newer house may run a furnace or water heater flue up through the attic. ENERGY STAR treats the open ring around that pipe as a leak, closed with light aluminum flashing set in high-temperature caulk. A sheet-metal collar keeps the insulation away from it, and codes usually ask for 1 inch of space around a metal flue.
Does attic insulation in Claremont need a permit?
Claremont City Hall can say whether Catawba County Building Services, the city itself or another office handles permits in Claremont; ask before work starts.
