Duluth winters do not forgive weak insulation. Hillside homes throughout Congdon Park and the East End sit exposed to wind coming straight off Lake Superior, and that wind finds every gap in an underinsulated wall or attic. Historic craftsman and colonial revival homes across the Hillside often carry original insulation from decades ago, never designed for today’s energy standards or Duluth’s persistent below zero stretches. Ice dams forming along roof edges near Woodland and Piedmont Heights are rarely just a roofing issue. They are usually a sign that heat is escaping through the attic and melting snow unevenly. Perrault Construction has helped Duluth homeowners fight back against extreme cold for over 50 years, delivering insulation upgrades engineered for lake wind exposure and this city’s older, character rich housing stock.
Duluth attics lose heat fast without proper coverage, driving up bills and forming ice dams along the eaves. We install attic insulation rated for the sustained cold this hillside city experiences each winter.
Older Duluth homes often have wall cavities insulated decades ago, if at all. We upgrade wall insulation to eliminate drafts and stabilize temperatures room to room.
When paired with new siding or windows, upgraded insulation delivers maximum efficiency for Duluth's historic homes while improving curb appeal at the same time.
Ice dams are common throughout Duluth's hillside neighborhoods. Correctly installed insulation reduces the temperature imbalance that causes them, protecting your roof and gutters.
We evaluate your Duluth home's current insulation performance and recommend targeted upgrades matched to your home's age, exposure, and construction style.
Cold drafts, uneven room temperatures, ice dams on the roof, and consistently high heating bills all signal inadequate insulation.
Heat escaping through an underinsulated attic melts roof snow unevenly, and that meltwater refreezes at the colder eaves, forming ice dams.
