Air Sealing Insulation FAQ


Frequently Asked Questions

  • How does air sealing help with Minneapolis's extreme temperature swings?

    In Minneapolis, due to its very cold climate, Minneapolis experiences some of the most extreme temperature variations in the United States, with scorching summers and frigid winters. Air sealing is crucial in our climate because it helps maintain a consistent indoor temperature regardless of outdoor conditions.

    By sealing gaps and cracks in your home's envelope, we prevent the loss of heated air in winter and cooled air in summer. This is particularly important during our brutal January cold snaps when temperatures can plummet below -20°F, or during July heat waves when we might see 100°F+ days. Proper air sealing can reduce your energy bills by up to 30% annually and significantly improve your home's comfort level year-round.

  • Can air sealing help prevent ice dams on Minneapolis homes?

    Absolutely! Ice dams are a common problem for Minneapolis homeowners due to our snowy winters and fluctuating temperatures. They occur when heat escapes through your attic, melting snow on your roof, which then refreezes at the eaves.

    Air sealing, especially when combined with proper attic insulation, is one of the most effective ways to prevent ice dams. By sealing air leaks in your attic floor, we prevent warm air from your living space from entering the attic. This keeps your roof temperature consistent, preventing the freeze-thaw cycle that leads to ice dams. Given that ice dams can cause significant damage to Minneapolis homes, investing in air sealing can save you thousands in potential repair costs.

  • How does Minneapolis's humid summer weather affect the need for air sealing?

    While Minneapolis is known for its cold winters, our summers can be quite humid, especially in July and August. This humidity can pose problems for homes that aren't properly air sealed.


    When warm, moist summer air enters your home through gaps and cracks, it can condense on cooler surfaces inside your walls or attic. This can lead to mold growth, wood rot, and other moisture-related issues. By thoroughly air sealing your home, we create a barrier that not only keeps your conditioned air in but also keeps humid outdoor air out. This helps maintain a comfortable humidity level inside your home and protects your structure from moisture damage.

  • Does air sealing affect indoor air quality, considering Minneapolis's urban pollutants?

    Yes, air sealing can significantly improve indoor air quality, which is particularly important in Minneapolis. As a major urban center, Minneapolis deals with various air quality issues, including particulate matter from traffic and industry, as well as high pollen counts in the spring and fall.


    When your home isn't properly sealed, these outdoor pollutants can easily enter through gaps and cracks. By professionally air sealing your home, we give you more control over your indoor air quality. You can filter the air coming into your home through your HVAC system, removing pollutants, allergens, and other particulates.

Why Proper Air Sealing is Vital for Minneapolis, MN


Minneapolis's frigid winters, warm summers, varying humidity levels, and extreme temperature fluctuations create the perfect environment for energy loss problems. Small gaps that go unsealed lead to numerous issues:

  • Higher Energy Bills: Conditioned air escapes while unconditioned outside air enters, forcing your HVAC system to work overtime to maintain desired temps. This spikes heating costs in winter and cooling costs in summer.
  • Temperature Inconsistencies: Unsealed cracks make it hard to keep things consistently comfortable room to room.
  • Excess Moisture Buildup: Warm interior air carries moisture outside in winter months, increasing chances for ice dams, mold, rot and more.
  • Poor Indoor Air Quality: Outdoor pollutants, pollen, dust and allergens enter freely through leaks.


Air Leak Assessment

The first step is a comprehensive leak assessment using advanced diagnostics like an infrared camera and blower door test. This locates:

  • Penetrations: We inspect all penetrations into your home including plumbing, electrical, vents/fans, fixtures, wiring holes, etc.
  • Framing Gaps: The edges between framing materials often open over time; we identify and mark these.
  • Cracks & Gaps: Intricate cracks in drywall, flooring, siding, etc. allow constant airflow. Our team meticulously maps crack locations.
  • Rim Joists: We check the wood border between foundation and walls for openings.
  • Attics & Basements: Floors and ceilings leak air which travels between home levels. We inspect for pathways.


Prioritize Vital Sealing Areas

Next we determine the most vital areas to seal based on:

  • Magnitude of Air Flow: We rank leakage areas from highest CFM readout to lowest.
  • Accessibility: We note areas that have obstructed access that may impact sealing method selection.
  • Location: Leaks connected directly to outdoors are sealed first before indoor-only gaps.
  • Scope of Work: If doing a full seal, we progress room by room. If sealing only certain areas, we start there.


Tailored Sealing Process

With all leaks mapped and ranked, our team then seals each penetration, crack, gap, etc. using the optimal sealing method for each unique situation:

  • Spray Foam: Foam expands into cracks, sealing effectively while adding insulation value.
  • Caulk: Silicone and other durable caulks last for years deep inside gaps.
  • Weatherstripping: Adhesive-backed for easy installation around moving parts like windows or doors.
  • Expanding Foam Sealant: Quickly fills larger voids with water-resistant foaming action.
  • Epoxy Sealants: Bonds nearly any materials together for permanent seals.

We only use top-performing sealing products rated for Durability, Flexibility and Airtightness to deliver long-lasting seals customized to your home's needs.

Our four-phase air sealing process finishes with science-backed verification and homeowner reporting including:

  • Blower Door Retesting: We retest each area with state-of-the-art equipment to confirm leak sealing effectiveness.
  • Thermal Imaging: Our infrared camera shows elimination of airflow in retested areas.
  • Homeowner Report: You receive a tailored binder of all diagnostics, sealing details, product data sheets, before/after images, energy savings estimates and more.

In addition to receiving records for your own peace of mind, these reports often greatly improve the resale value of an air-sealed home.
