Do I Need Professional Help to Seal My Air Ducts?

New spray-applied duct sealant technology can eliminate the “bridge effect” of brushed duct sealants. The duct sealant is atomized and is applied to the duct with a speed that allows it to fill the gaps.

Duct sealing

is one way to improve system efficiency and improve indoor air quality. Duct sealing simply involves blocking all the holes, leaks, and cracks in the duct network, usually with an aerosol. Sealing the ducts prevents the air conditioner from entering and dust, dirt, and other contaminants from entering.

Mastic air duct sealant is a more complicated option for preventing and stopping leaks, but it's very effective. It's a little harder to apply. Before using putty to seal air ducts, you must reinforce the joints with sheet metal screws. Large gaps in the air ducts must be reinforced with fiberglass mesh tape before applying the putty sealant for the air ducts. Once you've done the right amount of prep work, you can use a brush to layer the putty.

You can also use your fingers as long as you wear rubber gloves. You don't want this sticky, sticky air duct sealant to come into contact with your skin. Duct sealing is a great way to improve indoor air quality, reduce energy costs, and ensure that your HVAC system is operating as efficiently as possible. Others have used this technique with silicone sealant to seal duct joints, especially for the longitudinal sealing joints of galvanized round ducts. If your air ducts aren't working properly to distribute air throughout your home, you may need an air duct sealant.

Sealing air ducts prevents dust, dirt, dander, spores and other contaminants from entering, reducing the risk of respiratory diseases or allergies by keeping indoor air healthier overall. Hardcast recommends using Butyl Foil-Grip tape on galvanized steel ducting, duct panels, or flexible ducting. Aeroseal is one of the most expensive duct sealing options, but it's also very effective and provides long-lasting results. Not only must each section of the duct be sealed with the next, but the joints of each duct must also be sealed. Assuming that the cover is sealed to plaster and that the duct system is relatively airtight, there is no need for an airtight seal between the grid and the cover. However, I am skeptical about the longevity of the seal when using putty at the joints between sections of the duct.
