What it is, in plain English
Insulation slows heat transfer, but it doesn't stop airflow. The biggest energy losses in most Omaha homes come from warm air leaking up through gaps around can lights, top plates, plumbing penetrations, bath fans, and the attic hatch. Air sealing first — then insulating — is the difference between a comfortable house and a drafty one.
What's included
- Two-part spray foam at top plates and major penetrations
- Fire-rated sealant around recessed lights and chimneys
- Weatherstrip and insulate the attic access hatch
- Cover and seal soffit gaps where insulation falls into walls
- Insulate and seal HVAC ductwork in the attic
- Bath fan ducting redirected to vent outdoors (if needed)
Frequently asked
Why can't I just add more insulation on top of what's there?
You can — but you'll get maybe half the value. Air leaks bypass insulation entirely. Sealing first means every R-value of insulation you pay for actually does its job.
How much energy can air sealing save?
The Department of Energy estimates 10–20% on heating and cooling bills for a properly sealed and insulated attic. Most Omaha homes we work on see noticeably more even heating between rooms within a week.
