What Is Air Sealing?
Air sealing is the process of finding and sealing gaps, cracks, and openings that allow uncontrolled air movement into and out of your home. These air leaks are often hidden around attics, basements, windows, wiring, and plumbing penetrations. When left unsealed, they lead to heat loss, drafts, inconsistent temperatures, and unnecessary strain on your HVAC system.
Air sealing helps create a controlled, comfortable indoor environment and supports your HVAC system, allowing it to perform at its best.
Benefits of Air Sealing
A well-sealed home makes a difference you can feel every day. Not only does your monthly energy bill go down, but you’ll also notice fewer drafts and moisture problems throughout your home.
Here are some of the reasons Madison homeowners invest in our air sealing services:
Reduces Energy Bills
Air leaks force your heating and cooling system to work overtime. In winter, warm air escapes; in summer, hot air creeps in, and your HVAC system has to adjust constantly. Air sealing closes up the cracks and gaps that cause this energy loss.
Eco-Friendly
When conditioned air stays inside your home, your HVAC system uses less fuel and electricity to maintain a comfortable temperature. By reducing your energy consumption, air sealing services help lower your carbon footprint. It’s an easy upgrade that offers long-lasting benefits without requiring major home renovations.
Extends the Lifespan of Your HVAC System
With less strain, your HVAC system can operate more efficiently and last longer. After duct sealing in Madison, homeowners often notice their systems run quieter, maintain more consistent temperatures, and experience fewer breakdowns.
Better Indoor Air Quality
Air gaps around attics, crawl spaces, wall joints, and mechanical openings can allow dust, pollen, exhaust, mold spores, and outdoor pollutants to enter. Air sealing helps limit these unwanted particles from entering your home.
When paired with proper insulation and ventilation, air sealing can make indoor air feel noticeably fresher and more comfortable for your family.
Moisture Control
Air movement carries moisture. When humid or damp air slips through cracks around your home, it can lead to condensation, mold growth, and wood damage. By controlling airflow, you help keep your home dry and protected, especially during Wisconsin and Minnesota’s extreme seasonal shifts.

Where to Air Seal Your Home?
The key to proper home air sealing is identifying areas where conditioned air escapes, or unwanted outdoor air sneaks inside. Below are the common spots where air sealing makes the most impact:
Attics
Attics are one of the largest sources of heat loss in a home. Gaps around attic hatches, recessed lights, ductwork, plumbing penetrations, and framing joints allow warm air to rise and escape.
Doors & Windows
Even well-installed windows and doors can lose efficiency over time. Weatherstripping wears down, frames shift, and small gaps form along the edges.
Exterior Walls
Exterior walls have numerous small gaps for wiring, plumbing, and ventilation. These openings can create channels for air movement behind your drywall.
Basements & Crawl Spaces
Basements and crawl spaces are common entry points for outside air, humidity, and moisture. Rim joists, sill plates, and foundation gaps often allow large amounts of unconditioned air into your home.
Recessed Lighting & Electrical Outlets
Recessed lights, junction boxes, and outlets can create surprising amounts of air leakage. Because they penetrate your home’s insulation layer, they make easy pathways for air to move between rooms or escape outdoors.
