Mutiple duct problems.
One proven fix.
Rust. Asbestos. Crumbling fiberglass. Lingering smoke. Whatever’s wrong inside your ducts, we restore them in place — no jackhammers, no tear-out, no days of disruption.
If it’s in your ducts, we can fix it.
Rusted ducts under your slab? We restore them without breaking it.
Galvanized metal ducts buried in concrete eventually rust, collect water, and pull dirt into your air. The old fix was jackhammers, weeks of chaos, and a huge bill. Our patented coating rebuilds the duct from the inside — in place, usually in a single afternoon.
- ✔ No demolition. No concrete cutting.
- ✔ Seals rust, leaks, and cracks in one pass.
- ✔ You can be home the whole time.
Skip the removal. Seal the asbestos safely, in place.
Ripping out asbestos-lined ducts is expensive, disruptive, and risky. Our coating is rigorously tested and compliant under EPA standards for asbestos encapsulation — it locks the fibers down permanently so nothing gets into your air stream. Most homeowners save thousands versus abatement.
- ✔ EPA-compliant encapsulation system.
- ✔ No tear-out. No contaminated debris.
- ✔ Fraction of the cost of removal.
Crumbling fiberglass? We stop the fibers at the source.
Older homes often have formed-fiberglass ducts in floors and walls. As that fiberglass breaks down, loose fibers get blown through every vent in the house. Our coating stabilizes the surface and halts the release — permanently.
- ✔ Stops fiber shedding at the surface.
- ✔ Smooths the interior so airflow improves.
- ✔ Restores a duct you thought had to be ripped out.
After a fire, the smell lives in the ducts. We seal it in.
You can clean a duct system after a fire, but the smoke smell keeps coming back. Our encapsulation process locks odor-carrying particulates behind a sealed coating — so the smell doesn’t come back through the vents. Insurance typically covers encapsulation after a fire event.
- ✔ Permanent, not a fragrance or cover-up.
- ✔ Commonly covered by homeowner insurance.
- ✔ Restores the home you remember.
One coating. Eight problems, gone.
The first step is always a video inspection — a certified Duct Armor dealer walks through the issues with you before anything else happens.
Three easy steps to cleaner air.
Video Inspection
A certified dealer drops a camera into your duct system and walks you through exactly what’s going on — rust, moisture, asbestos, blockages. You see what we see, in real time.
Patented Coating Applied
Once we know what we’re up against, the dealer applies the Duct Armor coating from the inside. Typical residential application takes 3 to 4 hours — no demolition, no jackhammers, nothing torn out.
Breathe Easy
The coating cures quickly. You can start using your system the same day — with cleaner air, sealed ducts, and peace of mind.
Built for buildings
that can’t shut down.
We restore commercial ductwork in place — no tear‑out, no torn‑up ceilings, no days of downtime. Crews, classrooms, and tenants stay where they are while we work.
Lined ductwork is quietly shedding into the air your people breathe.
Most overhead and in‑ground commercial systems have sheet metal ducts lined with fiberglass or, in older buildings, asbestos. That liner is glued to the metal at the factory and is almost impossible to remove once it starts breaking down.
As it degrades, fine particles enter the air stream and get pushed out of every register in the building. Over time, that’s a real health issue for the people working under those vents every day.
Duct Armor coats the inside of the duct and locks those fibers in place — without ripping out ceilings or walls to do it.
Sealing the ducts cuts air leaks at every seam and pinhole. Conditioned air goes where it’s supposed to — not into the plenum or the dirt under the slab.
Many cities and utilities offer credits or rebates for duct sealing on commercial buildings. We can point you to programs in your area.
Concrete, sheet metal, galvanized, fiberglass, Transite, wood. If it carries air in your building, we can probably line it.
