Andover is a village in Ashtabula County (ZIP 44003), about 45 minutes from our shop at 7401 Ravenna Rd in Concord Township. Village in southeastern Ashtabula County near the Pennsylvania border, named by New England settlers of the Western Reserve in 1798; post office (originally ‘Sharon’) dates to 1815, renamed Andover 1826, incorporated 1883. Airlock Insulation has been dense-packing cellulose into Ashtabula County attics and walls for years, and Andover homes are a regular stop for our crews.
What we see in Andover homes. 469 housing units as of 2010 census, density ~342 units/sq mi; specific architectural era/style breakdown beyond that is unknown. Houses from that era were typically built with little or no wall insulation and thin, settled attic insulation, so the biggest wins in Andover 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 Pymatuning Lake / Pymatuning State Park (east of village), John R. Overly Recreation Park, Andover Township or anywhere else in Andover, 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: North Kingsville, Kingsville, Geneva-on-the-Lake, Williamsfield, Pierpont.
