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.
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.
Hundreds of small gaps in your envelope. Each one tiny. Combined: a fortune.
15–25% of conditioned air leaks out before reaching a room. You pay to heat your attic.
Tape fails. Caulk cracks. Each year unsealed gets a little worse than the last.
Both services typically pay back in 1–3 years through utility savings alone.
Our crew on the ladder, working the assembly from the inside out. No drive-by quotes, no shortcuts on the prep, no missed bays.
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.
Book Your Free AuditYour 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.
Measured before/after on real North Texas homes.
Pre/post pressure-tested on real North Texas homes.
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.
So you see the actual improvement, not just our word for it.
Pressure-test the duct system to measure baseline leakage. We know exactly where we started.
Walk the system, flag every accessible joint, fitting, plenum, and boot.
Hand-apply mastic to every connection. Reinforce with mesh on larger gaps. Let cure.
Retest to document the improvement. You see the number drop.
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.
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.
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.
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.
Air sealing and duct sealing are the highest-ROI services we offer. Most homes pay them back in 1–3 years.
