FAQ
Air Sealing questions, answered
Does sealing make my house stuffy?
A tight home needs controlled ventilation. We’ll check whether you need an HRV.
Is it messy?
Work is mostly in attics and basements, and we clean up afterward.
Should I seal before insulating?
Yes. Sealing first lets insulation perform as designed.
