Stillwater Insulation Contractor — Professional Home Insulation Services
Stillwater's victorian homes from the 1860s-1900s historic downtown, 1990s-2000s hilltop developments era deserve expert insulation that stops ice dams and cuts heating bills — without disturbing the character you love.
StillwaterInsulation Services Built for Minnesota's Toughest Climate
Stillwater homeowners know that Minnesota winters test every home. Nestled in the St. Croix River valley, Stillwater experiences cold-air drainage in winter that pools in the downtown area, making valley-floor homes significantly colder than hilltop properties. For the victorian homes common throughout Stillwater, that means higher heating bills, cold drafts, and uneven room temperatures that no amount of thermostat adjusting can fix.
RetroGreen Energy has insulated thousands of Twin Cities Metro homes since 2009, and we understand what Stillwater's housing stock needs. Minnesota's birthplace and oldest city, Stillwater has some of the state's most historically significant — and least insulated — homes, including pre-Civil War structures with rubblestone foundations. Whether your home has empty wall cavities, thin attic insulation, or an uninsulated basement, our BPI-certified team starts with a free diagnostic assessment that maps exactly where your home is losing energy — then creates a targeted plan to fix it.

Air Sealing
Temperature extremes in Stillwater amplify every air leak in your home. Air sealing stops the infiltration that insulation alone can't solve.

Foundation Insulation
Even poured concrete foundations in Stillwater lose significant heat without proper insulation. Foundation insulation keeps basements warmer and reduces moisture condensation.

Crawl Space Insulation
Historic downtown homes built into the river bluff often have partial stone-and-mortar basements that are naturally damp. Our encapsulation approach seals and conditions the crawl space for year-round comfort.
