The homes here, and how they leak heat.
St Paul is a city of old houses. Summit Avenue's mansions, the Victorians of Summit-University, and the 1910s–1920s homes filling Highland Park, Mac-Groveland, and Como were built with plaster walls, stone or block foundations, and, in most cases, uninsulated exterior walls and lightly insulated attics.
Many of these homes are story-and-a-half designs, with sloped ceilings and knee-wall attics that are notoriously hard to insulate well.
Areas we serve in St Paul
The right fix for St Paul winters.
In an old St Paul home, cold air typically leaks in low — through the rim joist sitting on a stone or block foundation — and out high, through the attic and story-and-a-half knee walls. We spray-foam the rim joist to seal the basement band and air-seal the attic and knee-wall areas to stop heat loss up top.
That top-and-bottom approach is what makes these grand but leaky houses comfortable and knocks down the ice dams that form on their steep roofs.
