Air Duct Sealing Service In Kauai, HI FAQs​

Duct sealing pricing varies based on the number of connections and the size of the duct system. Manual sealing using mastic compound is priced by the scope of the work. Aeroseal, an automated pressurized sealing system, is priced based on the linear footage of the duct system. We’ll explain both options and give you a clear quote.
Manual mastic sealing of accessible duct joints typically takes two to four hours for a standard residential system. The Aeroseal process takes about four to six hours from setup to completion, including testing and generating an airtightness report. Both approaches are completed in a single visit.
For ductwork that’s still structurally intact but leaking at joints, sealing is far more cost-effective than full replacement. It restores airtightness without the labor and material cost of tearing out and reinstalling duct sections. If the ducts are physically deteriorated, crushed, or disconnected in multiple places, replacement may still be the right answer.
We use mastic sealant applied to joints and connections for targeted repairs, and metal foil tape for accessible seams. For more complete sealing, we also offer Aeroseal, which uses pressurized airborne sealant particles that automatically find and seal leaks from the inside without requiring access to every duct joint.
A leaky duct system can waste 20 to 30 percent of conditioned air. Given Kauai’s high electricity rates and year-round AC use, addressing those losses can produce a meaningful reduction in monthly energy costs. The savings typically offset the cost of sealing within a year or two for most households.
