Cloquet Insulation Contractor — Professional Home Insulation Services
The ramblers and split-levels that define Cloquet were built with minimal insulation. RetroGreen retrofits these homes every day, delivering warmer winters and lower energy bills.
CloquetInsulation Services Built for Minnesota's Toughest Climate
Cloquet homeowners know that Minnesota winters test every home. Cloquet sits along the St. Louis River 20 miles inland from Lake Superior, getting the extreme cold of northern Minnesota without the moderating effect of the lake. For the bungalow homes common throughout Cloquet, 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 Duluth & Northern Minnesota homes since 2009, and we understand what Cloquet's housing stock needs. The devastating 1918 Cloquet Fire destroyed most of the original town, so the majority of homes were rebuilt in the 1920s-1930s — old enough to lack insulation but not yet historic enough for preservation protections. 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.
Cloquet homeowners may qualify for local utility rebates on qualifying insulation upgrades — call us for current eligibility, and we handle all the paperwork. Call (218) 414-7775 to schedule your free assessment and see how much you could save.
Insulation Solutions for Every Part of Your Cloquet Home
Each service targets a different part of your home's envelope. Most Cloquet homes benefit from a combination — we help you prioritize based on diagnostics, not guesswork.
Wall Insulation
Most Cloquet homes from the 1920s-1960s rebuilt after the 1918 fire era have completely empty wall cavities behind wood clapboard siding. RetroFoam injection fills every void without removing siding or disturbing interiors.

Attic Insulation
Ice dams are a persistent problem on Cloquet roofs. Proper attic insulation combined with air sealing solves both comfort and efficiency issues in one project.

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

Foundation Insulation
The concrete block foundations common in Cloquet conduct cold directly into living spaces. Foundation insulation keeps basements warmer and reduces moisture condensation.

Crawl Space Insulation
St. Louis River proximity creates elevated moisture levels; older block basements show efflorescence and mortar deterior. Our encapsulation approach seals and conditions the crawl space for year-round comfort.

Spray Foam Insulation
Spray foam is ideal for Cloquet homes where standard insulation can't reach — rim joists, cathedral ceilings, and irregular surfaces get both insulation and air sealing in one application.
