A County Seat With Every Era of House
Spray foam insulation in Indianola covers a wider range of housing than the newer suburbs. Indianola was founded in 1849 as the Warren County seat and incorporated in 1863, according to Wikipedia, and Simpson College dates to 1860. Point2Homes puts the median year built at 1979, with about 12.5% of homes built before 1940 and 16.5% from the 2000s. The city had 15,833 residents in 2020.
Older homes near the square
Houses near the old town center and the college often have the problems of any pre-war home: balloon framing, kneewalls, uninsulated walls and thin attic insulation. Air sealing the attic floor, capping open wall cavities and foaming the rim come first.
Colder than the city
Wikipedia's Indianola climate data lists about 30.8 inches of snow a year and a record low of -35F. That is the kind of cold that exposes every gap in a house.
Newer neighborhoods
Newer homes on the edges of town need what newer homes across the metro need: rim joist foam, attic sealing and insulation in rooms over garages.
Owners and renters
About 69.9% of Indianola's 6,152 occupied homes are owner-occupied. The National Balloon Classic is held here each summer.
A typical Indianola job
A 1920s house near the square might get attic floor sealing, caps on open wall cavities, a blown-in top-up toward R-49, rim joist foam and dense-pack in empty walls. A 2005 house on the edge of town would get rim foam, attic sealing and garage ceiling foam.
Costs
HomeGuide lists dense-pack at $1.60 to $4.20 per square foot and air sealing at $350 to $3,000 nationally. Older houses tend to need more sealing. Our written estimate is the final price.
Rental homes near the college
Rentals near Simpson College are often older houses. Attic sealing and rim foam are good first steps that make units easier to heat.
Snow load and attics
