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. Common areas for leakage can include:

  • Windows and doors
  • Exterior walls
  • Attics
  • Electrical fixtures
  • Wire penetrations
  • Basements and crawlspaces
  • Forced air ductwork

Seal in Comfort & Boost Your Insulation Performance

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.

Some of the services that WHI can provide 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.

Take your home performance audit information to the next logical step. Wisconsin Home Improvement can seal your home so you can start saving money and energy. Give us a call to discuss how we can make your home comfortable!

    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.
