FAQs

  • HOW LONG DOES THE PROCESS TAKE?

    The lining is typically completed in less than a normal business day. For larger commercial projects, this could vary.


    When necessary, we plan for 2 weeks between coats to allow for effective curing.

  • CAN I BE AT HOME DURING THE INSTALL?

    Yes, absolutely. Duct Armor is a non-toxic, non-invasive, water-based product, making it safe for children and pets. Not only can you be home during our application but can use your HVAC before we leave!

  • WHAT ABOUT WATER?

    Our material will not be damaged by water and has been used to create a more watertight barrier. As a part of our inspection, we’ll attempt to identify the source of any water problem, which should first be resolved before installing Duct Armor. Though not intended to be the sole water-proofing solution, when used in conjunction with other recommended repairs, Duct Armor has proven to significantly mitigate water intrusion.

  • IS THERE A SMELL?

    After each coat, the smell is similar to a freshly painted room. After a couple days with circulation, the only thing you’ll notice is improved airflow.

  • WHY 2 COATS?

    Most of the time a second coat is necessary to fully line the ductwork. Our second coat ensures your ducts have a solid coating and allows us to confidently stand behind our 15-yr. warranty.

  • DO YOU ALSO CLEAN THE DUCTWORK?

    Absolutely, and we offer bundled pricing discounts to reduce costs.

  • WILL IT INCREASE ENERGY EFFICIENCY?

    An air-tight system equals cost savings on your energy bill by reducing air loss.


    Our duct lining exceeds all current building codes in Pennsylvania. New energy codes require airtight systems in every home and building – Duct Armor far and away exceeds these standards, to include HERS testing.

  • IS DUCT ARMOR ONLY FOR HOMES?

    Duct Armor has been used in thousands of applications across the country. These include homes, estates, banks, office buildings, high rises, restaurants, schools, and universities. Regardless of the problem that brought Duct Armor to their attention, every one of our customers enjoys the benefits of improved infrastructure, great indoor air quality and reduced energy costs as a result of implementing the Duct Armor Solution.

  • WHAT'S THE PRICE?

    Every residential and commercial property is different- from ductwork condition, sizing, layout, material, needs, etc. Making a specific price range difficult to provide. That being said, our residential customers typically have their systems restored to better than new for only $5,000-7,000.

About Duct Armor


A material known as transite was used for in-slab ductwork until the 1980’s. Transite was the trade name for concrete, which used asbestos as the bonding agent. As air systems go through normal wear and tear, these asbestos fibers have become friable and then airborne, posing a risk to anyone exposed. 


Prior to Duct Armor, solutions were limited for ductwork that posed a health risk or was deteriorating. The alternatives are expensive and create construction zones that take weeks or even months to complete. One approach is to tear out the ductwork and replace it, sometimes cutting out floors or walls. The other is to completely fill and seal off in-ground ducts with concrete, before installing new ductwork in the walls and ceiling, and potentially a new furnace.


Recognizing the need for a cost effective and environmentally friendly method that restores and repairs ductwork, led to the creation of Duct Armor. The coating is a proprietary water-based latex material. Duct Armor is safe for children or pets, and has been rigorously tested and EPA approved to encapsulate asbestos and contains zinc to inhibit mold growth without the use of poisons, off-gassing or VOC’s.


Duct Armor non-invasive encapsulation is the safe and easy way to restore ductwork and air quality in your home or business, avoiding the chaos and costs of renovation projects. Remodeling your home and the relocation of air ducts into the attic, including purchasing a new furnace is no longer necessary.
