Spray Foam Insulation in Dennison, OH

Spray foam insulation in Dennison means working on homes built for the railroad. Wikipedia records that the Dennison Land Company laid out the town in 1865 when the Pittsburgh, Cincinnati and St. Louis Railway located its shops and yards here; the line was later absorbed by the Pennsylvania Railroad. The village incorporated in 1873 and was named for Governor William Dennison. The Dennison Coal Company also had mines south of town.

Railroad-era houses

Homes built for rail workers were practical frame houses, often close together on narrow lots, with little or no wall insulation, open stairways and bare rim joists.

Housing

The census counted 1,194 housing units in 2010, down slightly from 1,233 in 2000, and 2,709 residents in 2020.

Typical plan

Rim joist foam and attic sealing first, then blown-in and dense-pack walls.

Rows of similar houses

In a town laid out at once, many houses share the same plan, so the problems repeat: the same open stairway, the same chase beside the chimney, the same bare rim. Once we know the pattern, estimates are quick and the fixes are predictable. Owners with more than one property often have them done together.

Basements and rims

Many Dennison houses have basements with block or brick walls and a rim joist that has never been insulated. In winter, the first floor above feels cold no matter how high the thermostat is set. Closed-cell foam in each rim bay seals the gaps where the framing meets the foundation, and HomeGuide's national range for that job is about $2,000 to $2,500, often less on a smaller house. We check the walls below for dampness before spraying.
