That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Sealing Across Irving
Duct sealing in Irving typically runs $450 – $1,200 for a whole-home system, with most single-family jobs landing between $650 and $950.

You can reach us at (361) 326-5060 for a free written estimate.
We’ve worked in Irving long enough to know the local building stock isn’t uniform. The 1960s ranch on a slab in South Irving needs a completely different approach than the 15th-floor condo in Las Colinas with flexible ducting routed through a shared chase. Our Duct Sealing team carries both mastic and aerosol sealant rigs, plus the camera gear to inspect buried runs before we quote anything. That’s the difference between a crew that knows Irving and one that’s just passing through.

HVAC Duct Sealing in Irving
HVAC Duct Sealing in Irving addresses a problem most homeowners don’t notice until their energy bill climbs or one room stays stubbornly hot. The process involves finding leaks in your supply and return ductwork, then sealing them with mastic compound or aerosol sealant to restore proper airflow and prevent your conditioned air from escaping into the attic, walls, or crawlspace. In Irving’s market, a typical residential HVAC duct sealing job runs $650 – $950 for a single-family home, with larger homes or complex slab-duct systems reaching $1,100 – $1,200. High-rise units in Las Colinas with limited access often fall in the $450 – $700 range.
Sealing Methods We Use
We match the sealant to the duct material. For rigid galvanized steel common in older Irving homes, we brush on fiber-reinforced mastic at every joint and seam. For flexible ducting in newer construction, we use aerosol sealant particles that find leaks from the inside out, plus mechanical re-support of any sagging runs. Our Rotobrush rotary systems and Abatement Technologies negative-air HEPA units keep debris contained during the process.
When Sealing Beats Replacement
Not every leaky duct needs tearing out. If your galvanized runs in a South Irving ranch show surface rust but hold their shape, sealing the joints and pinholes can add 10 – 15 years of service. We camera-inspect first. You see the footage. Then we write down what sealing will cost and what it will actually fix.
Duct Repair in Irving
Duct Repair in Irving fixes the physical damage that sealing alone won’t solve: crushed flexible runs, disconnected joints, corroded galvanized sections, and holes from rodents or construction mishaps. A typical duct repair in Irving runs $280 – $550 for localized fixes like reconnecting a fallen flexible run or patching a corroded galvanized section. Extensive repairs involving multiple sections or under-slab access can reach $800 – $1,400. We always inspect with a camera before quoting, so you know whether you’re looking at repair, sealing, or full replacement.
Common Repairs in Irving’s Housing Stock
In South Irving’s 1960s-70s ranches, we regularly find original galvanized ducts with pinhole corrosion where condensate collected. The repair involves cutting out the damaged section and splicing in new galvanized or transitioning to flexible duct where access allows. In Las Colinas high-rises, we see flexible ducting that has sagged off its supports, creating low spots where condensate pools and mold starts. We re-support the run first, then seal.
Shared Chase Complications
Irving’s denser developments route multiple units through common vertical chases. Repairing one unit’s branch without isolating it properly pulls debris from neighboring runs into your system. We use temporary dampers and negative-air containment with our Nikro equipment so your repair doesn’t become your neighbor’s problem.
Trusted Brands We Service in Irving
We stock parts and sealants for systems using Aprilaire filtration components, Abatement Technologies HEPA containment gear, and Guardsman protective coatings. For Irving customers, that means faster turnaround. We don’t wait on a parts run to Dallas. Our vans carry mastic rated for Texas heat, flexible duct support straps, and transition fittings for both galvanized and modern flex systems. When we seal a duct in a Las Colinas high-rise or a South Irving ranch, we’re using materials that hold up to Irving’s 95°F attic temperatures and high humidity, not hardware-store products that skin over and crack in six months.
Common Duct Sealing Problems We See in Irving Homes
- DFW jet soot in shared chases. Homes near the airport, especially in the Valley Ranch and Las Colinas areas, pull fine black particulate from jet exhaust through leaky return ducts. Sealing the unit’s branch without addressing the shared chase leaves the soot path open. We isolate and seal both.
- Pinhole leaks in South Irving galvanized steel. Original 1960s-70s ductwork in neighborhoods like Plymouth Park and Sherwood Forest develops rust perforations that draw in attic insulation and pests. Camera inspection finds them. Mastic sealing or section replacement fixes them.
- Sagging flexible duct in newer construction. Las Colinas townhomes and high-rises often have flex duct that wasn’t properly supported, creating low spots where condensate collects and mold grows. We re-support before sealing, or the sealant fails under water.
- Under-slab moisture intrusion. Irving’s slab foundations route ductwork below grade. Pinholes in these galvanized runs draw in soil moisture during heavy rains, and occasionally roaches or rodents. We access through existing registers where possible, or discuss strategic rerouting if the slab run is too far gone.
Pricing for Duct Sealing in Irving, TX
A typical whole-home duct sealing in Irving runs $650 – $950 for single-family residences, with larger homes or complex systems reaching $1,100 – $1,200. Las Colinas high-rise units with limited access and smaller duct runs usually fall between $450 and $700. Duct repair, when needed alongside sealing, adds $280 – $550 for most localized fixes.
What moves the number: the linear footage of ductwork, how much is accessible versus buried in walls or under slab, whether we need to set up containment for a shared building chase, and if camera inspection reveals damage requiring repair before sealing can hold. We put all of this in writing before any work starts. One flat price per system. No per-vent add-ons, no equipment fees that appear at the door.

FAQs About Duct Sealing in Irving
It will, if the sealing addresses both your unit’s branch ducts and the shared vertical chase that connects them. We use temporary isolation dampers and negative-air containment to seal your run without pulling soot from neighboring units during the process. Call (361) 326-5060 and we’ll camera-inspect to show you exactly where the soot is entering.
Often yes, if the damage is limited to accessible joints and pinholes we can reach through existing registers. We camera-inspect the under-slab run first. If the corrosion is too extensive for spot sealing, we’ll tell you honestly and discuss options. Call (361) 326-5060 for a free inspection.
We install temporary backdraft dampers at your unit’s connection to the common stack, then seal your branch with the main stack still operational. Our Abatement Technologies HEPA containment captures any debris that dislodges. Most buildings never know we were there. Call (361) 326-5060 to schedule.
It can, if the wrong materials are used. We spec mastic and sealants rated for sustained attic temperatures above 130°F, which Irving attics hit regularly from June through September. Cheap hardware-store products skin and crack in that environment. Ours don’t. The 365-Day Done Right Promise covers any heat-related failure at no charge.
Yes, by eliminating the entry points. In South Irving’s older homes, we regularly find pinhole leaks in galvanized runs that serve as highways for pests from attic or crawlspace into living areas. Sealing those pathways, combined with proper screening at exterior intakes, closes the door. Call (361) 326-5060 and we’ll show you the entry points on camera.
