Duct Sealing
in Kingston, NY

The average home loses 20–30% of its conditioned air through leaky ductwork — air that escapes into unconditioned attics, crawl spaces, and wall cavities before it ever reaches a room. Duct sealing is one of the most cost-effective upgrades a homeowner can make, directly cutting energy bills while improving comfort.

How We Seal Your Ducts

We use a combination of diagnostic tools and professional-grade materials to locate and seal every leak in your duct system. The process starts with a pressure test to measure total leakage. We then physically inspect accessible ducts and apply mastic sealant or metal-backed tape (never standard duct tape, which fails quickly) to every connection, seam, and fitting. A final pressure test confirms the results.

Signs of Leaky Ductwork

• Rooms that are always too hot or too cold compared to the rest of the house
• High energy bills despite a functioning HVAC system
• Dust accumulation near supply registers
• HVAC running constantly but struggling to reach setpoint
• Humidity issues — dry in winter, humid in summer

Aeroseal Duct Sealing

For difficult-to-access ductwork, we offer Aeroseal — a professionally-administered process that injects polymer particles into the duct system under pressure. The particles bond to the edges of every leak they pass through, sealing gaps from the inside. It's the most thorough duct sealing technology available and comes with a 10-year warranty.
