Air Sealing

Air Sealing

Does your home feel drafty or full of cold air in the winter? It could be outside air leaking in, which can also lead to increased energy bills. An important step in improving your southeast Wisconsin home's energy efficiency is to seal the air leakage 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.

Insulation & Air Sealing: The Perfect Combo

Sealing the gaps and cracks in your home may help stop unconditioned outdoor air from infiltrating your home, but if your insulation is lacking, then those cold outdoor temperatures are still going to find their way into your living space. This is why we recommend always pairing an air sealing service with upgrading your insulation. Both of these home performance upgrades are essential to Wisconsin Home Improvement’s philosophy of “treating your whole house as a system.”

Signs Your Home Needs Air Sealing

Air leaks are often tiny holes and cracks, and they often hide out in the attic, crawl space, or around doors and windows so you can’t always see them. However, there are a few telltale signs that indicate added air sealing would improve indoor comfort and energy-efficiency. If you experience any of the following in your home, now’s the time to schedule service with a professional air sealing company:

  • You have rooms that are drafty.

  • Some areas of your home are especially hot or cold.

  • Your heating and air conditioning bills are high.

  • There is excess dust, especially in rooms located below the attic.

The benefits you can expect after professional air sealing 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 systems won’t have to work as hard to keep you comfortable. This will result in decreased energy use and ultimately lower monthly bills.

Improved Indoor Air Quality

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

Improve Your Home with Our Wide Range of Services

Wisconsin Home Improvement offers professional home performance audits, air sealing for new construction and existing homes, and a wide range of related services to keep your home comfortable, healthy, and efficient. Our services include:

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

  • Duct Sealing
    We’ll seal your ductwork to keep allergens, dust, and other contaminants from circulating through your home. Once your ductwork is sealed, we can also add insulation to your ductwork in basements and attics to conserve energy and allow your home's HVAC systems to function properly.

  • Wall Sealing
    We’ll seal air leaks around windows and doors, electrical outlets, vents, and more and install new insulation as needed — either dense-pack cellulose/fiberglass or spray foam — to improve home comfort and efficiency.

  • Attic Ventilation
    We’ll install ventilation in the attic to prevent ice dams in the winter and vent out excess heat in the summer. This is especially important for well sealed homes.

  • Kitchen & Bath Exhaust Ducting
    Often, we see kitchen and bathroom ductwork that is improperly installed or that vents air within the home rather than outside. We’ll correct and properly seal these ventilation ducts to prevent moisture buildup and mold.

    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...
