Spray Foam Insulation in Windsor Heights, IA

Spray foam insulation in Windsor Heights mostly means updating mid-century homes. Point2Homes gives the city a median year built of 1960, with 32.1% of homes built in the 1950s, 8.4% in the 1940s and 10.2% before 1940. Windsor Heights was incorporated on July 19, 1941, and annexed the Crestwood area, with about 1,300 people, in 1958, according to Wikipedia. It covers only 1.44 square miles and is surrounded by Des Moines, Urbandale, Clive and West Des Moines.

What 1950s houses need

Post-war ranches and story-and-a-halfs were built with modest insulation, and much of it has settled. The attic may have a few inches of rock wool or old fiberglass. Walls may have little or none. The basement rim is usually bare. A typical plan is attic floor sealing and a blown-in top-up, closed-cell foam on the rim, and dense-pack in any empty exterior walls.

Story-and-a-half homes

Homes with upstairs bedrooms under the roof have kneewalls and small attic spaces behind them. These are often the coldest rooms in the house. We foam the kneewalls and the floor behind them, or the roofline if the space is used for storage.

A stable, owner-occupied town

About 78.7% of the 2,229 occupied homes are owner-occupied. Many owners are updating houses they have lived in for years, and insulation is often part of a bigger project like a kitchen or basement remodel.

Ducts in the attic

Some mid-century homes have ductwork in the attic or in unconditioned spaces. We seal around ducts and flag any leaky joints.

A typical Windsor Heights job

A 1955 ranch might get attic floor sealing around fixtures and the hatch, a blown-in top-up toward R-49, closed-cell foam on the basement rim, and dense-pack in exterior walls if they test empty. Each part is priced separately so you can phase the work.

Costs

HomeGuide lists dense-pack cellulose at $1.60 to $4.20 per square foot and an average attic job at $1,000 to $2,700 nationally. Mid-century homes are usually easy to access, which keeps labor reasonable. The written estimate is the price.
