Seal your ducts
from the inside.
Leaky ductwork wastes the heating and cooling you pay for. We find and seal the leaks from inside the ducts — no tearing open walls or ceilings — and show you the before-and-after numbers.
Your leakage report
Sound familiar?
Ducts run through attics, walls, crawl spaces and ceilings — out of sight. When they leak, you pay to heat and cool spaces you don't live in.
According to ENERGY STAR, in a typical house about 20–30% of the air that moves through the duct system is lost to leaks, holes and poorly connected ducts.
Test. Seal. Prove it.
Aeroseal seals leaks from the inside of the ductwork, so we can reach leaks hidden behind walls and ceilings without opening them up.
Test
We cover your vents, connect our equipment and measure exactly how much air your ducts are leaking.
Seal
A sealant mist is blown through the pressurized ducts. It travels to the leaks and builds up across them until they close.
Prove it
We measure again and give you a before-and-after report, so you can see how much leakage was sealed.
A tighter system, a more comfortable home.
Even comfort
More of the air reaches the rooms it's meant for.
Less waste
Stop paying to heat and cool attics, walls and crawl spaces.
Cleaner air
Sealed ducts pull in less dust and debris from unconditioned spaces.
Easier on equipment
A system that isn't fighting leaks doesn't have to work as hard.
Homes, apartments and buildings.
🏠 Homeowners
Hot and cold rooms, high bills, dusty vents — especially in older homes and long duct runs.
🏢 Co-ops & apartments
Seal shared ductwork and exhaust shafts without opening up walls in occupied units.
🏗️ Commercial & contractors
Offices, schools and new construction — including leakage testing and sealing for projects that need to hit a target.
Aeroseal duct sealing across NYC, Long Island & Westchester
We seal ducts in homes, apartments and buildings throughout these areas. Pick yours:
Good to know
Do you have to open my walls or ceilings?
No. The sealant works from inside the ducts, so it reaches leaks you can't get to by hand — that's the whole point.
How long does it take?
Most homes are done in a single visit. We'll give you a time estimate with your quote, based on the size of your system.
Will it go into my rooms or furniture?
We cover the vents and protect the equipment before sealing, so the sealant stays inside the ductwork.
How do I know it worked?
We measure leakage before and after and hand you the report. No guessing.
Will it lower my energy bills?
Sealing leaks means less of the air you pay for is wasted, which can lower energy use. Savings depend on how leaky your ducts are, your equipment and how you use it — we'll be straight with you about what to expect.
