The homes here, and how they leak heat.
Minneapolis has one of the oldest housing stocks in the state. Huge swaths of the city — Longfellow, Nokomis, Powderhorn, Northeast — were built out in the 1900s through the 1920s as bungalows, four-squares, and story-and-a-half homes. Many of those walls were built with little or no insulation, and the plaster-and-lath construction hides balloon framing that lets air run straight from the basement to the attic.
Even the grand homes near Lake Harriet and Bde Maka Ska tend to have original walls and attics that have never been properly sealed. Beautiful, solid houses — but built for a different era of energy prices.
Areas we serve in Minneapolis
The right fix for Minneapolis winters.
In a century-old Minneapolis home, the biggest wins are almost always air sealing and the attic. We seal the top plates, chimney chases, and balloon-framed wall cavities that leak warm air, then bring the attic up to a proper R-value. That combination is what finally stops the ice dams that plague the city's steep older roofs every February.
Where walls are open during a remodel, closed-cell spray foam lets us insulate and air-seal old exterior walls that could never hold batts well. In tight city lots with shared walls and additions, that control over air movement makes a real comfort difference.
