Services / Aeroseal Duct Sealing

Aeroseal duct sealing in Northwest Indiana.

Most homes lose 25 to 40% of conditioned air through duct leaks. We seal them from the inside so you stop paying to heat the attic.

How it works

Seal the leaks you can't reach.

Your ductwork is full of small seams and gaps that leak conditioned air into attics, crawlspaces, and walls. You cannot reach most of them, which is why drafty, uneven rooms are so common.

Aeroseal works from the inside out, sealing leaks throughout the duct system so the air you pay to heat and cool actually reaches your rooms. The result is more even temperatures and lower energy bills.

Common questions

Good to know.

How much air do ducts really lose?

Industry research puts typical losses at 25 to 40% of conditioned air through duct leaks.

Is Aeroseal messy?

No. It seals from inside the ducts, so there is no tearing into walls or ceilings.

Will it lower my energy bills?

Sealing leaks means less of the air you pay for is wasted, which typically lowers heating and cooling costs.

How long does it take?

Most homes are completed in a single visit. We give you a clear timeline up front.
