From Finnish Farms to Family Homes
Spray foam insulation in Esko covers a community with farm roots. Finnish immigrants settled the area between the 1870s and the early 1900s, and the town grew around Esko's Corner, a store Alex Esko built in 1919 at what is now Thomson Road and Highway 61. The Lincoln School followed in 1920 and families moved in. Today Esko is a census-designated place of 2,082 people with 747 housing units and only 3.5 percent vacancy.
What we see here
A mix of older farmhouses, mid-century homes and newer houses on larger lots. Many properties have a detached garage, shop or old barn. The older homes often need attic sealing and rim joist foam; the outbuildings often need foam on steel or framing.
Owner-occupied and staying
With 747 homes and very low vacancy, most Esko houses are lived in year round. That means the heating bill matters every winter, and upgrades pay back over years of ownership.

Esko is in Carlton County: Climate Zone 7 and frost Zone I. Ceilings target R-49 under the 2012 IECC table, and footings go 5 feet deep. Nearby Cloquet's design temperature in Minnesota's energy rule is -20F.
Wells, septic and rural access
Rural properties sometimes have narrow drives or soft ground in spring. Let us know about access when you book so the spray rig can get close to the building.
