The Premier Insulation Contractors Serving St. Paul, MN Homeowners

While our insulation services can target your attic, roof, walls, or floors, many St. Paul homeowners don’t realize that up to 40% of a home’s energy loss happens in the attic. If your insulation is outdated or underperforming, air leakage can make it difficult to maintain comfortable indoor temperatures—no matter how hard your HVAC system works.

Our team specializes in air sealing and insulation upgrades designed to reduce energy loss and improve overall home performance. Since 1979, we’ve helped Twin Cities homeowners stay comfortable year-round with solutions like closed cell spray foam, fiberglass, and blown-in insulation.

Proper insulation works best when combined with professional air sealing. Many St. Paul homes experience air leakage through small gaps in attics, walls, and around windows, which can increase energy costs and reduce comfort. Our air sealing services are designed to eliminate drafts and improve the overall performance of your insulation system.

Installing The Right Type Of Insulation: Spray Foam, Fiberglass, & Cellulose

In order to provide you with the most effective insulation possible, our highly experienced team of attic insulation contractors will conduct home performance testing before beginning your project. Our blower door test and diagnostic tools will show us where the thermal energy transfer is occurring in your home, which allows us to determine which type of attic insulation will provide the most efficient barrier between your living spaces and the outdoors. We can install three types of insulation in your attic:

  • Fiberglass insulation – Consisting of rolls of spun glass fibers that fit neatly between attic beams and joists, this insulation traps pockets of air in order to prevent temperature transfer.
  • Spray foam insulation – Since this insulation type expands to fill the available space, it creates an air-tight seal between your living area and the outdoors while also resisting mildew and mold growth.
  • Blown-in cellulose insulation – This recycled paper product settles into difficult-to-access areas in order to create a dense barrier that protects your home from outdoor temperatures and noise infiltration.

Regardless of the type of insulation that your home needs, you can rest assured that our products will provide you with unbeatable protection. That’s because, in addition to their insulating properties, they all possess an exceptional fire rating and excellent resistance to household pests like insects.

Insulation Reviews From St. Paul Residents:

"I signed another contract with Lindus Construction — this time to spray foam and fully seal my attic, followed by an additional top layer of insulation. This is not a simple job. My home has a very complex Unico high-velocity air conditioning system running throughout the attic, and Lindus still took it on without hesitation."
