Driving down the street, you drive over a nail and your tire goes flat. If you're lucky, you've got a can of aerosol leak sealer in your trunk. You fill the tire from the can, the leak is sealed, and you're on your way. It's a simple analogy for a similar type of technology that Aeroseal Inc. is counting on to seal the leaky ductwork in your home.
Robert Hageman started Aeroseal with a partner, Dr. Mark Modera, in 1997. They had a product - no, a mission - but little in the way of national exposure or marketing clout to carry it out.
