Insulation Services for Winter-Ready Homes

Spray Foam Insulation

Spray foam is the most effective way to seal your home against winter cold. It expands into gaps and cracks that other insulation types cannot reach, stopping air infiltration at the source.

  • Seals air leaks and insulates in one application
  • Ideal for attics, rim joists, crawl spaces and walls
  • Open-cell and closed-cell options for different applications
  • Most effective solution for drafty older homes

Blown-In Insulation

Blown-in insulation is a fast, cost-effective way to add R-value to existing attics and hard-to-reach cavities, helping your home hold heat through a Wisconsin winter.

  • Great for attic top-ups and wall cavities
  • Covers irregular spaces and around obstructions
  • Available in fiberglass or cellulose materials
  • Minimal disruption to finished spaces

Fiberglass Insulation

Fiberglass batts and rolls are a proven, budget-friendly choice for walls, floors, and attics in new construction and remodel projects across SE Wisconsin and Northern Illinois.

  • Standard option for new construction and additions
  • Works well in open wall cavities and attic floors
  • Available in a range of R-values
  • Cost-effective for larger square footage projects

Mineral Wool Insulation

Mineral wool offers strong thermal performance along with fire resistance and sound dampening, making it a solid choice for specific residential and commercial applications.

  • Higher fire resistance than standard fiberglass
  • Good acoustic properties for interior walls
  • Performs well in exterior wall assemblies
  • Available for residential and commercial projects

Cellulose Insulation

Cellulose is a dense, recycled-content blown-in material that fills attic spaces and wall cavities effectively, reducing air movement and improving winter warmth.

  • Dense pack reduces air infiltration in walls
  • Made from recycled materials
  • Good option for older homes with irregular framing
  • Effective for attic retrofits and additions

FAQs

How quickly can you get out for an estimate before winter?

We schedule free estimates as quickly as our calendar allows, and we prioritize homeowners heading into the cold season.

The sooner you reach out, the sooner we can get you scheduled before the cold really sets in.

In most cases, yes. Drafts are caused by air leaking through gaps in the building envelope, not just thin insulation. Spray foam expands into cracks and voids that other insulation types leave open, sealing air movement at the source. Common problem spots include the attic floor, rim joists along the foundation, and crawl spaces. We will look at your home and tell you honestly whether spray foam is the right fit or whether another product would do the job better.

We install spray foam, blown-in, fiberglass, mineral wool and cellulose insulation. Spray foam is often the best fit for air sealing and high-performance applications, but the right choice depends on your home, your project and your budget. We give you an honest recommendation rather than defaulting to the most expensive option.

Every home is different, so pricing depends on the area being insulated, the product used and the scope of the work.
