What Sets Gunner Apart as an Insulation Contractor in Cottage Grove

Hiring the right insulation contractor matters. A thorough job requires more than simply adding material. It means evaluating existing conditions, identifying air leaks, and selecting the right products for each area of the home. Gunner Insulation & Roofing approaches every project as a full-service insulation contractor, not just an installer. That distinction means Cottage Grove homeowners receive an honest assessment of what their home actually needs before any work begins.



The team is licensed, bonded, and insured, and carries decades of combined experience working in Minnesota's demanding climate. From older homes with inadequate existing insulation to new construction requiring code-compliant installations, Gunner has the expertise to handle the full scope of residential insulation work.


Why Cottage Grove Homeowners Choose Gunner Insulation & Roofing

The right insulation approach depends on where in your home it's needed. Blown-in cellulose and fiberglass work well for attic floors, while closed-cell spray foam offers superior air-sealing for rim joists and wall cavities. Gunner offers spray foam insulation, fiberglass batt insulation, and eco-friendly Green Fiber Cellulose insulation that is moisture resistant and carries a lifetime guarantee.



Key benefits Cottage Grove homeowners may see after upgrading:

  • Lower energy bills as conditioned air stops escaping through walls, ceilings, and floors.
  • More consistent indoor temperatures with fewer cold spots in winter and stuffy rooms in summer.
  • Reduced risk of ice dams, which form when attic heat melts roof snow unevenly.
  • Moisture and mold prevention through proper air sealing combined with insulation.
  • Quieter living spaces thanks to high-density materials that dampen exterior noise.

What to Expect From the Installation Process

Most residential insulation jobs in Cottage Grove, MN, are completed in a single day. Gunner's process includes a free walkthrough, evaluation of existing insulation and air leaks, material and R-value recommendations, clean, efficient installation, and a final review with the homeowner. 

  • How Do I Know If My Home Needs New Insulation?

    Common warning signs include high energy bills, drafts near outlets or baseboards, cold walls, and an HVAC system that runs constantly. Ice dams forming along your roofline each winter are a strong indicator that attic insulation and air sealing need attention.

  • What Type of Insulation Works Best in Minnesota?

    The best material depends on location. Blown-in fiberglass or cellulose is often ideal for attic floors, while closed-cell spray foam may perform better for rim joists and basement walls. An experienced insulation contractor in Cottage Grove, MN, can recommend the right combination based on your home's age, construction, and energy performance.
