In this segment, Derek Cole describes how AeroSeal duct‑sealing works. He explains that the system first pressurizes a home’s ductwork to quantify air loss (often around 20% of capacity) and locate leaks. An adhesive, similar in smell to school glue, is then introduced; it travels with the airflow and seals the identified leaks. For large holes, Cole recommends manually patching the opening before applying AeroSeal to avoid wasting material. He emphasizes that roughly 95% of homes suffer from leaky ducts and presents AeroSeal as a proven solution, citing years of experience and numerous satisfied customers.

But regardless of the board or metal duct, uh, you can go back with and install air seal as you seal the ductwork. It works on pressure. So again, we pressurize that duct system, it says, hey, we're losing this much air, we're losing, say, 20%, we're losing 20% capacity because of leakage. Uh, so we go back with AeroSeal and it works on that pressure. So actually finds where we're losing pressure and it seals it with that glue adhesive. Uh, kind of has an Elmer's glue kind of school glue smell to it, but it can actually go in there and seal all these places where you're losing air, losing because of leakage. It can actually seal those areas. Now for the really bad holes or really bad situations, of course we're gonna, you know, try to manually fix that best we can and then seal it. That way we're not wasting a whole bunch of time or a whole bunch of glue to unseal a giant hole. We're obviously going to patch that and then we're going to seal that patch to the system. So it's as good as new. But it's unbelievable. I mean, 95% of homes have leaky ducts, but there is a solution. It's called the AeroSeal. Uh, we— again, we've been doing it for years. We've had so many, so many happy clients.
