Underground Duct Lining FAQs
Video inspections typically take between 1-3 hours, but there are other factors to consider like the size of your home and how accessible your vents are.
Most any type of pipe can be lined with our duct lining material. The most common types of underground pipes are galvanized, concrete, transite, clay tile, PVC or cardboard. Our product is designed with a high adhesion value and compatible with all of these types of pipe.
Absolutely! Lining underground transite air ducts permanently encapsulates harmful asbestos fibers and ensures that they never make their way through your air duct system and into your home.
Our product contains 3% zinc, so mold is unable to grow inside the newly lined pipe. Mold typically grows inside air ducts when there are holes in the pipe – allowing dirt and moisture to enter the pipe. Our product covers and seals these holes and prevents future mold growth in the duct.
