Air Sealing

air leaks diagram

Does your home feel drafty or cold in the winter? It could be outside air leaking in. An important step in improving your southeast Wisconsin home's energy efficiency is to seal the tiny gaps and cracks that can rob you of energy dollars and prevent home heat loss. As part of your home energy assessment, Wisconsin Home Improvement uses a blower door test in addition to infrared thermal imaging and diagnostics to identify where you home is leaking air.

Where is Air Leakage Occurring in Your Home?

  • Exterior walls

  • Attics

  • Electrical fixtures

  • Wire penetrations

  • Basements and crawlspaces

  • Windows and doors

  • Forced air ductwork

Signs Your Home Needs Air Sealing

  • You have rooms that are drafty

  • Areas of your home that are significantly hotter or colder than the rest of your house

  • Especially high heating and air conditioning costs

  • Excess dust, especially in rooms that are located below the attic

Boost Comfort & Increase Insulation Performance with Air Sealing

Air leakage can account for as much as a 30% loss in energy by allowing conditioned air to leak out and outside air to leak in at the worst times. Once your home has been evaluated, the team at Wisconsin Home Improvement can recommend ways to seal your home to keep it tight and energy efficient. The benefits you can expect include:

  • Greater Home Comfort

By preventing drafts and helping your insulation do its job to stabilize temperatures throughout your home, you’ll be more comfortable whether it’s cold or hot outside.

  • Lowered Air Conditioning & Heating Bills

Since you won’t be bothered by drafts or temperature differences, your home’s air conditioning and heating system won’t have to work as hard to keep you comfortable. This will result in decreased energy use and ultimately lower bills month after month.

  • Improved Indoor Air Quality

Air sealing will prevent moisture and pollution from making its way into your home. This reduces the chances for mold growth and other indoor air quality issues, so you and your family can breathe easier.

Services that Wisconsin Home Improvement Provides Include:

  • Air Sealing: The gaps and cracks illuminated by the infrared thermal imaging can be sealed to keep outside air from seeping in.

  • Duct Sealing: Sealing ductwork can provide benefits in many ways. Sealed ductwork keeps allergens, dust and other contaminants from circulating through your home. Once the ductwork is sealed, adding insulation to ductwork in basements and attics can conserve energy and allow your home's HVAC systems to function properly.

  • Wall Sealing: Walls have many sources for leaks: around windows and doors, electrical outlets and vents. In many homes, poor or damaged wall insulation also can allow outside air to leak in through tiny gaps. If wall leaks are small or concentrated, they can be sealed individually to improve comfort. In many cases, installing new insulation in an existing home—either dense-pack cellulose/fiberglass or spray foam—will amplify the effects of air sealing to make a big difference in your comfort.

  • Attic Ventilation: Keeping the airflow in your attic is important in all seasons: in winter, ventilation can prevent ice dams, while in summer, attic ventilation releases heat that can make your AC work harder than necessary. A well-sealed home relies on good attic ventilation to exhaust excess heat.

  • Kitchen & Bath Exhaust Ducting: So many times, we see kitchen and bath ductwork that is improperly installed or vents air within the home rather than outside. Correcting ventilation and properly sealing the ventilation ducts can prevent moisture buildup and mold.

    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.
