Jefferson is a village in Ashtabula County (ZIP 44047), about 35 minutes from our shop at 7401 Ravenna Rd in Concord Township. Established 1803 by Gideon Granger; historic village and the county seat of Ashtabula County, with a 19th-century abolitionist history tied to Joshua Giddings and Benjamin Wade. Airlock Insulation has been dense-packing cellulose into Ashtabula County attics and walls for years, and Jefferson homes are a regular stop for our crews.
What we see in Jefferson homes. 1,450 housing units (2020 census) with a 5.7% vacancy rate; predominantly owner-occupied single-family homes typical of a small, historic Ohio county-seat town, including restored 19th-century structures in the village core. Houses from that era were typically built with little or no wall insulation and thin, settled attic insulation, so the biggest wins in Jefferson 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 Ashtabula County Courthouse, Jefferson Town Hall, Giddings Law Office (restored) or anywhere else in Jefferson, the process is the same: a free in-home consultation, an itemized quote, and most jobs finished in a single day.
Nearby communities we also serve: Ashtabula, Austinburg Township, Rock Creek, Jefferson Township, Plymouth Township.
