Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
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 Repair & Sealing Across Irving
Duct repair and sealing in Irving typically costs $280-$850 for residential work, with most homes in Valley Ranch and south Irving falling in the $400-$650 range depending on whether we’re reconnecting separated flex collars or resealing an entire sheet-metal trunk line. Our crews are dispatched from our Dallas-Fort Worth office and carry full inventories of flex duct, mastic, and metal fittings sized for the exact housing stock we encounter in Irving. Call (940) 240-8552 for a written estimate before any work begins.
We’ve been working in Irving since 2013, and the pattern is unmistakable. Valley Ranch homes built between 1982 and 1995 are hitting the 30-40 year mark where original fiberglass-lined flex duct and mastic seals simply fail under North Texas heat cycling. South and west Irving neighborhoods from the 1960s and 1970s present a different problem: original sheet-metal trunk lines with degraded seals that leak conditioned air into attics and crawl spaces. Our Duct Repair & Sealing team documents every finding with before-and-after photos, so you see exactly what was wrong and what changed.

Our Duct Repair & Sealing Services in Irving
Duct Sealing
Sealing is often the most cost-effective repair we perform in Irving, especially on 1960s-70s south and west Irving homes with original sheet-metal trunk lines. The mastic applied decades ago has dried, cracked, and pulled away from joints and boots, leaking conditioned air into attic spaces. We remove the degraded material and apply fresh mastic sealant to every joint, boot connection, and plenum seam. On a typical 1,800-square-foot home in the Heritage District area, this runs $280-$450 and restores 15-25% of airflow capacity that was being lost to leakage.
Flex Duct Repair
Valley Ranch’s 1982-1995 build-out left tens of thousands of homes with original fiberglass-lined flex duct and mastic seals now 30-40 years old, so Irving’s east side holds a denser pocket of failing residential duct connections than any competing suburb. The flex collars dry out and separate under North Texas heat cycling, dumping cooled air into attics instead of bedrooms. We replace crushed or separated flex runs with insulated duct sized to the original HVAC design, reconnect collars with mechanical fasteners plus mastic, and photograph every connection. A Valley Ranch homeowner on a 1990-built street off MacArthur Blvd called because two bedrooms ran 6-8°F warmer than the rest of the house. Our tech ran a camera inspection and found a crushed supply run pinched behind a joist and a disconnected flex collar at the air handler, both original 1990 install. We reconnected the collar, replaced the crushed flex with insulated duct, sealed every joint with mastic, and the temperature split closed to under 2°F. Typical flex repair in Valley Ranch: $350-$620.
Metal Duct Repair
Older Irving homes with galvanized sheet-metal trunk lines develop rust perforations, separated slip joints, and failed drives at the plenum connection. We fabricate patch panels, reseat and seal slip joints, and replace damaged sections with matching gauge metal. This work is more common south of SH-183 and west of Belt Line Road, where the housing stock predates flex duct adoption. Metal repair runs $450-$850 depending on accessibility and the extent of corrosion.
Duct Insulation
When flex duct insulation has degraded or metal ducts lack adequate wrap, we install new insulation with proper vapor barriers. This matters in Irving’s attic spaces where summer temperatures exceed 140°F and uninsulated or poorly insulated ducts lose 20-30% of cooling capacity before air reaches the register. Insulation work typically accompanies sealing or repair and adds $180-$340 to the job.

BeforeAfterTrusted Brands We Service in Irving
Our trucks carry professional-grade equipment from Rotobrush, Nikro, Honeywell, and Aprilaire, with replacement parts and fittings inventoried for the duct configurations common in Irving’s two dominant housing eras. We don’t run to a supply house mid-job. That means a Valley Ranch flex repair or a south Irving metal trunk resealing finishes on schedule, with the documented photo record delivered before we leave. Equipment is named on every written estimate so you can verify specifications independently.
Common Duct Repair & Sealing Problems We See in Irving Homes
- Separated flex collars in Valley Ranch. Original 1982-1995 Valley Ranch flex duct connections dry out and separate at the collar after 30+ years of North Texas heat cycling, dumping conditioned air into attics instead of rooms. We find this on roughly half of our Valley Ranch camera inspections.
- Degraded mastic on sheet-metal trunk lines. In 1960s-70s south and west Irving neighborhoods, the mastic seals on original sheet-metal trunk lines crack and pull away, leaking at every joint and boot. The homeowner notices weak airflow at distant registers and higher summer electric bills.
- Internal fiberglass shedding. Fiberglass-lined flex from the original build sheds internally, coating the blower motor and evaporator coil and cutting airflow long before the homeowner notices a problem. The camera shows a fuzzy gray buildup that shouldn’t be there.
- Crushed or pinched supply runs. In attics where storage or prior work has compressed ductwork, we find flattened flex runs that restrict airflow to entire zones. A crushed 10-inch supply run in a Valley Ranch attic can reduce bedroom airflow by 40%.

FAQs - Duct Repair & Sealing in Irving
If two or more rooms consistently run 5°F or more off the thermostat setting, or your summer electric bills have climbed without rate changes, you likely have separated collars or crushed runs that cleaning won’t fix. A camera inspection shows the difference between debris buildup and mechanical failure. We perform this inspection as part of our standard estimate process and show you the footage before recommending any work. Call (940) 240-8552 to schedule - estimates are free.
Yes. Sheet-metal systems need mastic reapplication at joints, boots, and plenum connections, sometimes plus rust repair. Flex systems need collar reconnection, crushed run replacement, and mastic at mechanical fasteners. The tools, materials, and labor hours differ. We specify which approach your home needs in the written estimate, never a generic “duct sealing” line item.
Irving’s summers routinely exceed 100°F for weeks at a time, forcing HVAC systems to run almost continuously from May through September. This constant thermal expansion and contraction accelerates mastic drying and flex collar degradation. A seal that might last 40 years in a milder climate fails in 30 here. That’s why Valley Ranch’s 1982-1995 builds are hitting failure threshold now, not later.
Yes, though these jobs require system mapping first. Multi-tenant office campuses along the SH-114/O’Connor Road corridor often have poorly documented HVAC zoning across floors and suites, with ductwork shared across spaces subdivided and renovated multiple times since the 1980s. We map the system before quoting, then seal only the runs serving your suite with documented before-and-after airflow verification. Commercial sealing in Las Colinas typically runs $680-$1,400 depending on system complexity.
We start with a camera inspection of every accessible run, then deliver a written estimate with photos showing what we found. Upon approval, we seal or repair per the scope, test airflow at each register, and deliver a complete photo record of before, during, and after. The 365-Day Done Right Promise covers all work in writing. Most residential jobs in Irving take 3-5 hours. Call (940) 240-8552 for a written estimate - no obligation.
