Residential Air Duct Repair

In-Slab Ductwork

Duct Armor is perfect for ductwork located under the slab. Our process requires no demolition for the full restoration of rusty ducts. Our process will eliminate dirt, mold and bacteria in your air duct system.

Encapsulating Dangerous Asbestos Ductwork

Many homes have both overhead and in ground ductwork containing asbestos. Duct Armor has been rigorously tested and is compliant under the EPA standards for asbestos encapsulation. This means you don’t have to have the asbestos ductwork removed, but instead can have it safely encapsulated saving thousands of dollars.

Fiberglass Ductwork

Many older homes have formed fiberglass ductwork between floors and inside walls. Over time, the fiberglass deteriorates and causes a severe health hazard by releasing these fibers into your air stream and your family’s lungs. It is very dangerous. Our coating process will stabilize the fiberglass surface and halt further disbursement of these deadly fiberglass fibers.

Reducing Smoke Odors

After a fire, your duct system can be cleaned but the smoke smell will linger. This is also true if someone has smoked in the home. Duct Armor’s encapsulation process will completely eliminate smoke odors. Insurance typically will pay for encapsulation after a fire event.
