Professional air sealing keeps the unconditioned, outdoor air from infiltrating your living space. In most homes, there are air leaks in a number of places — both along the home’s exterior and throughout its interior. Air leakage is most commonly found in:

  • Exterior walls

  • Attics

  • Electrical fixtures

  • Wire penetrations

  • Basements and crawlspaces

  • Windows and doors

  • Forced air ductwork

Finding Your Home’s Air Leaks with WHI

Not every air leak in your home is visible to the naked eye. The home performance specialists at Wisconsin Home Improvement use infrared cameras and blower door tests to locate each and every hole and gap:

Blower Door Test

With a blower door test, all of the doors and windows of your home are shut, and a large temporary fan is attached to the front door. This fan creates a negative pressure inside of your home, and gives your WHI technician a reading of exactly how air tight your home is.

Infrared Cameras

An infrared camera uses heat mapping to show exactly where your home is hot and cold. This informs your technician exactly what kind of holes and gaps to seal, and where they are.


Air leakage can account for as much as 30% of the energy loss in your home. It also undermines the effective of your insulation and allows outside contaminants like pollen, dirt, and excess moisture to seep in, harming your home’s indoor air quality.

With less unconditioned air leaking into your home, your heating and cooling equipment uses much less energy to keep your home cozy in the winter, and cool in the summer. This in turn lowers your energy bills, and reduces the wear and tear that your furnace and air conditioner incur through each Wisconsin season.

To eliminate air leakage, improve the effectiveness of your insulation, and enhance indoor air quality, you need comprehensive air sealing. Once the team at Wisconsin Home Improvement has evaluated your home for leaks, we’ll air seal throughout and recommend solutions like ventilation to keep your home healthy and energy efficient.

Don’t be fooled—upgrade your home insulation and air sealing before you update your home heating and cooling equipment! Wisconsin Home Improvement has the home performance expertise you need. Call us at 262.345.9922 or contact us to schedule your air sealing today.

    Dear Steve, 

    We at Grace are so pleased with the quality of work and the professionalism of the crew that did the insulation. Mike and Igor were so respectful of the building and its contents, and so nice to everyone in the congregation who was working at church.

  • Cindy S.

    I really feel compelled to give a "shout out" to everyone I have come into contact with at WHI. First off - Jody. You are so friendly and helpful on the phone, forgiving me for my inability to "on-line sign", switching up of dates, declining work and then changing my mind.

  • Tim S.

    Steve, just a side note and I would not send this if it was not completely true - Mike and Pete were both fantastic. I was impressed. We had just had other major construction and have many comparatives for the work WHI did. I would come home and never know they had even been there.

  • Mike & Erin M.

    We wanted to provide feedback on our experience with Peter, who did our home energy audit.  We felt he went above and beyond what was expected of him.  He was very thorough and was genuinely concerned about any issues causing inefficiencies in our home.  He explained things in terms we...
