The Challenge: A homeowner in a 1920s farmhouse near North Fond du Lac was experiencing severe drafts and frozen pipes during winter, despite having a high-capacity furnace. The Solution: Our team performed an energy audit and identified the rim joists and attic knee walls as major air leak sources. We applied closed-cell spray foam to the basement rim joists and open-cell foam to the attic roof deck. The Result: The homeowner reported an immediate stabilization of indoor temperature and a notable decrease in heating fuel consumption during the following winter season, with no recurrence of frozen pipes.

For the harsh winters in Fond du Lac, closed-cell spray foam is often considered superior. It provides a high R-value per inch and acts as a vapor barrier, preventing moisture from condensing inside walls when the temperature drops significantly.
Yes. Ice dams are caused by heat escaping into the attic and melting snow on the roof. By air-sealing the attic floor or insulating the roof deck with spray foam, we stop heat loss, keeping the roof deck cool and preventing the melt-freeze cycle that causes dams.
In most cases, yes. To ensure the foam adheres properly to the substrate (studs and sheathing) and creates an effective air seal, we typically vacuum out old, dirty, or settled fiberglass or cellulose before application.
Homes with documented energy efficiency upgrades, such as spray foam insulation, often command higher market interest. Buyers appreciate the long-term cost savings on utilities and the assurance of a comfortable, draft-free living environment.
Insulation acts as a blanket to slow down heat transfer, while air sealing closes the physical holes and cracks that allow air to move in and out. For maximum efficiency, you need both; spray foam is unique because it insulates and air seals simultaneously.
