Mastic

What Is Mastic?

There is a big misconception that duct tape is a good remedy for repairing faulty ductwork; unfortunately, this just isn’t true. The glue on duct tape breaks down fairly easily when applied to ductwork, and provides, at most, a temporary solution. This is why, when professional perform duct sealing on your Cary home, you won’t see duct tape used, ever; instead, you’ll see a product called mastic.
