Insulating the County Seat
Spray Foam Insulation in Jasper works on a city with a long building history. Named for Revolutionary War hero Sergeant William Jasper, the town was settled around 1815 and incorporated on August 18, 1886, the same year the Kansas City, Memphis and Birmingham and the Sheffield and Birmingham railroads were completed through it. The population went from 200 in 1886 to more than 3,000 in 1890.
Older housing
That history means a lot of older homes: early 20th century frame houses near downtown, mid-century brick ranches, and newer homes on the edges of town. The 2020 census counted 6,300 housing units in Jasper with 9.4% vacant. Older houses usually need attic sealing and depth, crawl space work and, often, wall insulation.
A shrinking city, staying owners
Wikipedia notes Jasper was among the five fastest-declining Alabama cities of its size in the 2010s, and the median age was 41.8 in 2020. People who stay tend to stay in their homes, and fixing cold floors and hot upstairs rooms is worth it for them.
Historic homes
Jasper has several National Register sites, including the John Hollis Bankhead House and the Jasper Downtown Historic District. In older homes we work from the attic and crawl space and fill walls through small holes, so finished rooms stay intact.
