Service · Air & HVAC Duct Sealing

The hidden 40% of your energy bill.

Air leaks and leaky ducts that nobody sealed. Insulation can't fix a house that's leaking conditioned air through gaps you can't see. We track them down and seal them properly, before any insulation goes in.

The Two Problems

Invisible. Always getting worse. Rarely addressed.

Air infiltration and HVAC duct leakage account for an enormous share of total energy waste in North Texas homes, typically 30–45% combined. Almost no insulation contractor addresses them because they're harder to sell than a thick blanket of fiberglass.

Air infiltration

Hundreds of small gaps in your envelope. Each one tiny. Combined: a fortune.

Duct leakage

15–25% of conditioned air leaks out before reaching a room. You pay to heat your attic.

Compounds over time

Tape fails. Caulk cracks. Each year unsealed gets a little worse than the last.

Fast payback

Both services typically pay back in 1–3 years through utility savings alone.

This is how proper air-sealing happens.

Air sealing is unforgiving work. The difference between a 5% leak and a 50% leak is whether the crew showed up, stayed late, and did the detail work. We do.

Air Infiltration Sealing

Where the biggest leaks hide.

Your home's envelope has hundreds of small penetrations: top plates, electrical boxes, plumbing stacks, recessed lights, chimney chases, attic hatches. Each leaks a tiny amount. Together they leak a fortune.

  • Top plates between conditioned space and the attic
  • Recessed/can lights, older non-IC-rated cans leak constantly
  • Chimney and flue chases, open chases are massive air bypasses
  • Plumbing penetrations through floors and ceilings
  • HVAC register boots never sealed to the drywall

HVAC Duct Sealing

Stop paying to condition your attic.

Your duct system is the delivery vehicle for everything your HVAC produces. When 15–25% of conditioned air leaks out of joints, fittings, and connections, most of it into your attic, you're literally paying to heat and cool the wrong space.

We hand-apply mastic sealant to every joint, take-off, boot, and plenum. Mastic is the industry standard for a reason, it's thick, paintable, durable, and seals gaps that foil tape and cloth tape can't. Done right, it lasts the life of the ductwork.

Our Process

Four steps. Measured before and after.

So you see the actual improvement, not just our word for it.

Test

Pressure-test the duct system to measure baseline leakage. We know exactly where we started.

Inspect

Walk the system, flag every accessible joint, fitting, plenum, and boot.

Seal

Hand-apply mastic to every connection. Reinforce with mesh on larger gaps. Let cure.

Re-test

Retest to document the improvement. You see the number drop.

Air & Duct Sealing FAQs

What homeowners ask before booking.

How much can duct sealing save me?

Homes with significant duct leakage (20%+) typically see cooling bills drop 10–20% from duct sealing alone. We measure before and after, so you see the actual improvement on your home.

Can't I just use foil tape on the duct joints myself?

You can, and it'll fall off within a couple of years. Most cloth and foil tapes are not rated for duct sealing despite being sold that way. Mastic is the industry standard for a reason.

Do you spray-foam-seal everything?

No. Different gaps call for different sealants. Foam is right for some, caulk for others, fire-rated sealants where code requires, gasketed covers for can lights. We use the right one for each spot.

How long does the job take?

Air sealing for a typical home is one day. Duct sealing is usually a day to a day-and-a-half. Most homes we bundle into a two-day project.

Fix the Invisible Stuff

Stop paying to heat your attic and cool the outdoors.

Air sealing and duct sealing are the highest-ROI services we offer. Most homes pay them back in 1–3 years.
