Conneaut is a city in Ashtabula County (ZIP 44030), about 50 minutes from our shop at 7401 Ravenna Rd in Concord Township. Historic Lake Erie lakefront city (the northernmost city in Ohio) at the mouth of Conneaut Creek, settled in 1799 (originally named New Salem), incorporated as a village in 1832/1834 and a city in 1898/1902; known for over seven miles of Lake Erie shoreline, beaches, and a harbor/shipping history. Airlock Insulation has been dense-packing cellulose into Ashtabula County attics and walls for years, and Conneaut homes are a regular stop for our crews.
What we see in Conneaut homes. Unusually large stock of pre-World War II architecture; median construction year around 1950, with roughly 40-41% of homes built before 1940. 5,515 housing units per the 2020 census with a relatively high (16.1%) vacancy rate. Houses from that era were typically built with little or no wall insulation and thin, settled attic insulation, so the biggest wins in Conneaut 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.
