Yes. sealants we use are formulated for occupied homes and buildings, not industrial-only environments.

Duct Armor is a water-based acrylic coating that inhibits mold and bacteria growth without using poisons or harsh chemicals. It's been rigorously tested for fire safety and off-gassing. Because it's water-based and doesn't rely on pesticidal chemicals to fight mold, it doesn't require EPA registration — a safety profile similar to a water-based paint rather than a chemical treatment.

It is safe for homes with kids, pets, and anyone with respiratory sensitivities once applied and cured, and your technician will walk you through the process before work begins.

Yes, Duct Armor applies over fiberboard, including cases where the board is already showing mold, mildew, or deterioration — this is exactly the situation Duct Armor's coating is built for.

The deciding factor is the board's condition, not its material. If your fiberboard is structurally intact but leaking air or If it's showing mold, water damage, or physical breakdown, Duct Armor restores and protects it instead of requiring a full replacement. We'll tell you honestly which situation you're in during your free assessment.

Duct Armor: Yes. Its coating is specifically formulated to seal over existing mold and mildew and inhibit further growth — this is the primary use case Duct Armor was built for, not an edge case.

If your ducts have visible mold or mildew, Duct Armor is the right product. We'll confirm your situation during your free assessment.

Duct cleaning removes dust and debris from inside your ducts. Duct sealing closes the gaps and holes that let conditioned air escape before it reaches your rooms. They solve different problems — a clean duct can still leak, and a sealed duct can still be dirty. We specialize in sealing; if cleaning is also needed, we'll tell you honestly during the assessment.

Yes, for both residential homes and commercial properties. It takes about 45 minutes: We run a live recorded robot camera inspection. If you don't move forward, you keep the report and owe us nothing.

Sealing your ducts doesn't void manufacturer warranties on your HVAC equipment. In fact, reducing strain on an overworked system that's been fighting leaks can help it last longer. We also maintain what we seal, so your system stays clean and your results hold up over time.

It depends on your building's size and how much leakage we find — which is exactly why the assessment is free and comes first.
