Why asbestos shows up in slab homes

Asbestos in older slab-home ductwork is a real concern, but Duct Armor offers a way to make those ducts safe again without tearing up your floors.

Why asbestos is in your ducts

Many slab-on-grade homes from the 1960s–1970s used asbestos-containing transite pipe for in-floor duct systems. When those ducts crack or deteriorate, tiny asbestos fibers can enter the air and pose serious long-term health risks.

Why removal is so difficult

Taking out asbestos ducts in a slab usually means:

Jackhammering concrete and damaging finished floors.
Very high abatement and reconstruction costs.
Strict safety rules and the risk of fiber release during removal.

For many homeowners, full removal is not realistic.

How Duct Armor helps

Duct Armor is a thick, rubberized liner that is installed inside your existing ducts through the vents. It:

Encapsulates asbestos surfaces so fibers are sealed in and can’t enter the airstream.
Meets EPA guidelines for asbestos encapsulation while restoring airflow.
Also helps with rust, water damage, and dirt intrusion common in slab ducts.

Homeowners can typically stay in the house during the process because the material is water‑based and low-odor.

A smart option for older slab homes

For older slab-on-grade homes, rerouting ducts overhead can be messy and expensive. Encapsulating asbestos ducts with Duct Armor:

Avoids breaking up your slab and disrupting your home.
Protects your indoor air from asbestos and other contaminants.
Provides a cost-effective alternative to full asbestos removal and rebuild.

If you suspect your in-slab ductwork contains asbestos, Duct Armor can turn that risky, crumbling system into a clean, sealed, and usable duct network again
