Sealing Air Leaks

During an energy assessment, technicians will perform a blower door test to pinpoint any air leaks within the building envelope. Air leaks are typically simple to repair with caulk, spray foam, or weatherstripping. Any identified air leaks can be professionally sealed by Lantern's certifed professionals during the energy assessment.


When is a draft more than just a draft?
The average home—even when well-insulated—contains enough cracks, leaks, and gaps between building materials to add up to a 14" by 14" hole in the wall! Air leaks are commonly found around recessed lighting, door and window frames, and dropped ceilings, but they can also occur in less obvious areas, such as the attic or crawl-space, where you might not feel a draft.
