Enviroliner offers a solution for sealing air ducts that are in the concrete slab. If your home is more than 10 years old and the air ducts run through the concrete foundation, they are probably beginning to deteriorate. Our latex-based sprayed liner offers a solution without demolition or disruption to the home. The sealing is accomplished directly through the floor registers and most homes can be completed in one day. We offer services for both commercial & residential properties.
