Add Mastic Duct Sealant

For an additional fee, Plenums Made Easy can seal the inside seams of your assembled plenums with professional-grade mastic (water-based duct sealant), saving you the time and mess of doing it yourself.

Mastic helps ensure an airtight, energy-efficient seal that prevents air leakage and improves overall system performance. It’s a great option for contractors or installers who want their plenums delivered ready to install right out of the box.

Please Note: This charge is applied per plenum.
