Harpersfield is a township in Ashtabula County, about 35 minutes from our shop at 7401 Ravenna Rd in Concord Township. Rural township on the northwestern edge of Ashtabula County, site of the first regular settlement in the county (1798, led by Col. Alexander Harper); historically agricultural with early mills and forges; part of the city of Geneva extends into its north, and the unincorporated community of Unionville sits in its northwest. Airlock Insulation has been dense-packing cellulose into Ashtabula County attics and walls for years, and Harpersfield homes are a regular stop for our crews.
What we see in Harpersfield homes. Mixed rural/suburban housing stock with the largest construction wave in the 1970s (346 units), roughly 27% of units built before 1960; predominantly single-family detached homes (806 units) with a notable share of mobile homes (150 units), consistent with farmhouses and mid-century ranch/colonial construction. Houses from that era were typically built with little or no wall insulation and thin, settled attic insulation, so the biggest wins in Harpersfield are usually a dense-pack wall injection, air sealing the attic floor, and bringing the attic up to R-49 or better with blown-in Nu-Wool cellulose.
Whether you’re near Unionville, Harper Cemetery (grave of Col. Alexander Harper), part of the city of Geneva or anywhere else in Harpersfield, the process is the same: a free in-home consultation, an itemized quote, and most jobs finished in a single day.
