What Happens During a Professional Duct Sealing Appointment?

You may be wondering what the professionals do during a duct sealing service vs. making duct sealing a DIY job. Here is a general overview of what to expect when a Custom Comfort ClimateCare expert performs duct sealing on your home:

  • Thorough inspection of your ductwork: Your technician will conduct a thorough inspection of your ductwork system to assess the problems. This ensures that all the problem areas in your ductwork will be detected and repaired as needed.
  • Professional sealing process: Once your technician is aware of all the problem areas, he or she will use mastic and professional-grade tape to seal cracks, holes, and loose connections. Mastic is a fibrous adhesive that hardens into a seal, and during a professional duct sealing appointment, it applied with a caulking gun onto all problem areas. Once the mastic has been applied, a piece of foil or fiberglass tape is placed over the mastic. The mastic will cure, in which time it will become a hard seal. For broken connections, the two ends are brushed with mastic, then reconnected and stabilised using metal binding that is secured with sheet metal nails. The mastic hardens, reinforcing the re-sealed connection.

This process is used for all the problematic areas of your ductwork, allowing your air duct system to regain efficiency and function the way it is supposed to.

Why Can't I Just Use Duct Tape?

It can seem confusing that a product with the word "duct" in it can't be used to seal your ductwork, but the simple truth is, it can't. This is because the glue from the duct tape breaks down rather quickly, typically within 3 months' time, so the seal won't stick. The bottom line? Always hire a professional for duct sealing.
