The air your family breathesshouldn't be making them sick.
If your ducts run under the slab, years of moisture and rust are quietly pouring into every room of your home. DuctArmor restores them from the inside, with no jackhammers, no demolition, and no need to replace costly HVAC equipment.
Your ducts are buried in the concrete and you can't see them or the changes happening.
In a slab home, the ducts are buried under the concrete, in dirt. They're probably the most overlooked problem a house can suffer from.
You don't need to demo your foundation to fix it.
A new duct, formed inside your old one.
We clean the inside of your existing ducts, then spray a proprietary polymer coating onto the walls. It bonds, hardens, and forms a new smooth surface that seals rust, cracks, and corrosion.
The original ductwork stays exactly where it is, where it's efficient. No need to open up the slab or convert to an overhead HVAC system. It saves thousands of dollars, and yet offers a better, more efficient, and more comfortable solution.

Same duct. Drag to see the difference.
These are unretouched photos from real homes. Every job we do starts here, with a rusted, pitted, sometimes leaking piece of metal, and ends with a smooth, sealed, airtight new surface.
Three steps. One day. Zero demolition.
We inspect with a camera.
A certified dealer feeds a video scope through an existing register. You see exactly what we see: rust, debris, separations, water.
We clean every inch.
Loose rust, dust, and debris are removed through the existing openings. No demolition. No digging. Your flooring and foundation stay intact.
We coat the inside.
Our proprietary water-based polymer is sprayed through the duct in two full coats, forming a new smooth surface that seals everything in one continuous piece. The system can be used the same day and dries within a few days.
Give your family back the air they deserve.
Most in-slab ducts were installed decades ago and were never meant to last forever. If yours are leaking, rusting, or full of moisture, you're breathing a little bit of that every day. We can fix your ducts in just two visits: one for the first coat, one for the second.

Restore duct systems without shutting down the building.
Schools, clinics, office buildings, and government buildings face both underground and above-ground duct problems: anything from mold to fiberglass insulation fibers entering the airstream. Ducts running through unconditioned spaces also leak, which drastically lowers efficiency and drives up heating and cooling costs.
