The homes here, and how they leak heat.
Northfield, home to Carleton and St. Olaf, has a rich stock of older homes — Victorians and early-1900s houses clustered around the historic downtown and the Cannon River, many now serving as family homes or student rentals. These homes have plaster walls, balloon framing, and little to no original insulation.
Newer construction on the outskirts adds conventional homes to the town's older core.
Areas we serve in Northfield
The right fix for Northfield winters.
Northfield's older homes lose heat the way all century-old houses do — air leaking up through balloon-framed walls and an under-sealed attic, and in through a bare rim joist on the old foundation. Air-sealing those pathways and insulating the attic and rim joist is what makes these historic homes warmer and cheaper to heat.
For the steep old roofs common on Victorians here, a well-sealed attic is also the real cure for the ice dams that form each winter.
