Spray Foam Insulation in Allouez, WI

Spray foam insulation in Allouez is almost always a retrofit. The village counted 5,512 housing units in 2000 and 5,575 in 2020, so nearly every house here was already standing at the turn of the century, and many are far older. Allouez has been its own village since 1874, and it sits between the Fox River on the west and the East River on the east.

High ownership

About 81.5% of Allouez homes are owner-occupied, one of the highest rates around Green Bay. Owners who plan to stay tend to fix comfort problems properly: sealing the attic floor, foaming the rim joists and filling walls that have nothing in them.

What we find in older houses

Many homes here have plaster walls with empty cavities, attics with a thin layer of old fill and basements with open rims. We dense-pack cellulose into the walls through small holes, seal and top up the attic, and foam the rim. Before filling any wall we check for knob-and-tube wiring, which should not be buried.

Near the rivers

Houses close to either river can have damper basements. We look at the foundation for seepage first. Closed-cell foam on the rim and walls handles humidity well, but standing water needs to be solved before any insulation goes on.

Costs to expect

HomeGuide's national figures put dense-pack cellulose at $1.60 to $4.20 per square foot and blown-in for exterior walls at $1,900 to $7,800 for a typical house. Rim joist foam runs about $2,000 to $2,500 and attic jobs about $1,000 to $2,700. We price your house after a visit, area by area, in writing.
