Why Duct Sealing Works

The process of duct sealing is a thorough one. First, your technician will inspect your entire ductwork system to find all the area of fault. This will include holes, cracks and joint disconnections. Once all the problem areas have been identified, your technician will coat these areas with a fibrous adhesive known as mastic. When applied, this adhesive looks like a paste, but it hardens into a durable yet flexible seal that stops air leakage, blocks outside air, contaminants and odors from entering your home, and allows your system to work at the capacity it was meant to work at instead of straining to compensate for the air loss. For joints that have come disconnected, your technician will brush mastic on the ends of each joint, put them together, wrap them with metal binding and secure the bind with sheet metal nails. The mastic will cure into a durable, long–term seal.

How Do I Know I Need Duct Sealing?

Ductwork is usually placed behind walls, so it can be tough to tell when your ductwork has gotten faulty. Here are some signs you can look for to see if your ductwork needs help, and you can always call our pros to take a look as well:

  • Whistling sounds – it’s normal to hear air moving through your ductwork when your HVAC system begins a new cycle, but a consistent whistling sound can indicate that air is pushing through holes and cracks.
  • Excessive moisture, dirt and/or dust in your home – have you noticed that the air quality in your home has decreased significantly? Is there a lot more dirt, dust and moisture than before? Not only do you lose air with faulty ductwork, outside elements have direct access to your home via the holes and cracks.
  • High energy bills – significant air loss due to faulty ductwork forces your HVAC system to work harder to compensate for the loss. The result is that your HVAC system uses more energy, and this will be reflected in your monthly utility bills.
