Spray Foam Insulation in North Fond du Lac, WI

Spray foam insulation in North Fond du Lac covers homes from a century of growth. The village went from 1,960 residents in 1910 to 2,291 in 1950, 3,286 in 1970 and 5,378 in 2020, all on about 2.15 square miles. Despite the name, it lies northwest of the city of Fond du Lac.

Older homes

Houses from the early part of the century tend to have empty walls, thin attics and old foundations. We seal and fill the attic, foam the rim and dense-pack walls where wiring allows.

Mid-century and newer homes

Homes from the 1960s and 70s growth spurt usually need attic sealing and rim joist foam. Newer ones need help mainly at the rim and over garages.

Close to the lake

The village sits near the south end of Lake Winnebago. We check basements for moisture before insulating below grade.

Costs

HomeGuide's figures: attic jobs $1,000 to $2,700, rim joist foam about $2,000 to $2,500. Written estimates after measuring.

Rooms over garages

Many homes from the village's later growth have attached garages, some with rooms above. A floor over an unheated garage is one of the coldest spots in a house. Foam in the joist bays warms the room and blocks fumes from below, and sealing the kneewalls stops the drafts along the sides.

What to expect from the visit

We check the basement for moisture and measure the rim joist, then measure the attic depth and look for bypasses around lights, pipes and the hatch. Older homes get a wiring check before any wall work. The written quote lists each area, with material, thickness and R-value. Many North Fond du Lac homes need only the attic and rim, which is often a one-day job. We tell you how long to stay out of any sprayed area before we start.
