Exacting Air Sealing Process

At Illinois Valley Insulation, we like to do things right. That's why we finish up your insulation project with carefully targeted air sealing measures.

Targeting the Little Places Where Leaks Occur

Many insulation firms will do the basics and then move on. But at Illinois Valley Insulation, we increase the efficiency of your home by looking for those little areas where air may still be getting in and out.
  • Chimney areas
  • Top plates
  • Areas around can lights
  • Bathroom and kitchen fans
We seal those spaces so you get a completely insulated home or business.
