Fast, Reliable Duct Repair & Sealing Across Irving
Duct repair and sealing in Irving typically runs $340-$890 for most residential jobs, with flex-duct replacement in Valley Ranch homes often landing in the $520-$740 range due to attic accessibility challenges. Our crews are dispatched from the Dallas-Fort Worth office and carry the full equipment roster needed for Irving’s specific housing stock, from Rotobrush negative-pressure extractors to Guardsman-supported flex-duct replacement kits. Call (469) 405-6133 for a written estimate before any work begins.
We’ve been documenting the inside of Irving ductwork since 2013, and the photo records from this city look different than anywhere else in our service area. Valley Ranch’s original 1980s flex-duct installations are failing in predictable patterns that technicians working newer Frisco or McKinney subdivisions simply don’t encounter. The clay soil shifts. The ducts sag. Standing water collects in the belly. Our Duct Repair & Sealing team has replaced and sealed hundreds of these runs, and we photograph every one.
Why CleanRun Air Duct Cleaning Dallas Is Irving’s Preferred Duct Repair & Sealing Company
Irving homeowners research before they call. We built our process around that fact.
Every job starts with Haven Standard Clause 1: a written price delivered before any panel comes off, with no “call for a quote” evasion. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we identify each crew member by name before arrival. The 365-Day Done Right Promise is backed in writing on every job, not buried in a policy manual.
We’ve served more than 52,000 homes since 2013, every one with a documented photo record of every duct run before and after work. In Irving specifically, our crews know the difference between a Valley Ranch flex-duct belly-sag repair and a Las Colinas commercial metal-duct seal. That local knowledge saves time and prevents misdiagnosed work.
Our equipment roster includes Nikro HEPA-filtered extractors, Honeywell media filters, and Aprilaire whole-home air cleaners - brands customers can verify independently. We stock flex-duct, mastic sealant, and mechanical fasteners locally for Irving jobs, which means replacement work doesn’t wait on parts orders.
Our Duct Repair & Sealing Services in Irving

Flex Duct Repair
Valley Ranch flex-duct failures are our most common Irving call. The original 1980s installations are now 25-40 years old, and North Texas expansive clay soil has shifted slab foundations enough to separate joints and collapse support strapping. Our techs find belly-sag so severe that standing water and mold colonies form in the low spots. We replace degraded sections with Guardsman-supported flex duct, re-strap at code-compliant intervals, and photograph every connection before closing the attic.

Mastic Sealant Application
Brush-on mastic outperforms foil tape for Irving’s thermal cycling. Attic temperatures hit 150-160°F for months, which degrades adhesive-backed tapes while mastic remains flexible. We apply mastic to every joint, collar, and plenum connection, then pressure-test the system to verify seal integrity. The photo record shows where mastic was applied and how thick - documentation that matters if you sell your Valley Ranch home and the buyer’s inspector asks questions.

Air Leak Repair
Jet-exhaust particulates from DFW International Airport and mountain cedar pollen (December-February) push Irving’s indoor particulate loads well above inland suburbs. Leaky return ducts pull attic air directly into the system, bypassing filtration entirely. We pressurize the duct system, locate leaks with smoke pencils and thermal imaging, then seal them. For homes downwind of flight corridors near MacArthur Boulevard or Highway 183, this repair has measurable impact on what the EPA notes is already elevated indoor PM2.5.

Duct Insulation
Poorly insulated connections in Irving’s superheated attics condense moisture during cooling season, creating mold growth at the air handler. We replace degraded insulation with vapor-barrier-wrapped material and seal the vapor barrier to the duct with mastic. This is standard on every flex-duct repair we perform in Valley Ranch and North Irving.

Common Duct Repair & Sealing Problems We See in Irving Homes

- Valley Ranch flex-duct belly-sag from foundation movement. Expansive clay soil shifts 1980s slab foundations, separating flex-duct joints and causing mid-span sag where standing water and mold colonies form. We replaced a separated section in Valley Ranch last month where the camera showed a 3-inch debris build-up at the first elbow and standing water in the belly below.
- Attic heat degradation of flex-duct inner liners. Irving’s 150-160°F attic temperatures for four-plus months annually break down the plastic inner liner of original flex-duct, creating pinhole leaks that reduce airflow and pull fiberglass insulation into the airstream. The photo record shows the difference between intact liner and degraded material.
- Condensation-driven mold at poorly insulated connections. When cool supply air meets uninsulated or degraded-insulation duct in a 160°F attic, moisture condenses. We find mold at air handler plenum connections in Irving homes every summer, particularly in Valley Ranch and North Irving neighborhoods where original insulation has compressed or torn.
- Jet-exhaust and pollen loading overwhelming filtration. DFW Airport downwind particulates and mountain cedar pollen settle deep into trunk lines after overwhelming standard return-air filters. Leaky ducts make this worse by bypassing filtration entirely. Source removal under negative pressure, followed by sealing, is the repair that lasts.
Pricing for Duct Repair & Sealing in Irving, TX
A typical flex-duct section replacement in Irving runs $340-$520 per run, depending on attic accessibility and whether the plenum connection also needs resealing. Full system mastic sealing for a single-zone Valley Ranch home is usually $480-$680. Metal duct repair in older North Irving homes runs higher, $620-$890, due to the labor of accessing and patching galvanized trunk lines. Duct insulation replacement adds $180-$340 per run.
What moves the number: attic accessibility (Valley Ranch’s tight truss spacing slows work), extent of mold remediation required before sealing can begin, and whether the air handler platform needs releveling due to foundation shift. Every estimate includes the full scope in writing before work starts, per Haven Standard Clause 1. We also offer a Free Second Opinion on any competitor’s written estimate - bring the quote, and we’ll put our number next to it.

FAQs - Duct Repair & Sealing in Irving

Every 2-3 years for Valley Ranch homes, which is more frequent than the 4-5 year interval typical for newer suburbs. The combination of clay-soil foundation movement introducing debris through separated joints, and DFW Airport downwind particulate loading, creates accumulation rates we document as measurably higher than in Richardson or Garland. Homes directly under flight corridors near MacArthur Boulevard or Highway 114 should lean toward the 2-year interval. Call (469) 405-6133 for a camera inspection and written recommendation.
Camera inspection of every run, replacement of degraded or separated sections with supported flex duct, mastic sealing of every joint and collar, pressure testing to verify seal integrity, and a documented photo record delivered as part of the job file. In Valley Ranch specifically, we also inspect and replace support strapping where clay-soil foundation shift has caused mid-span sag. The written scope specifies exactly which runs are being replaced versus sealed, so there’s no ambiguity about what was done.
Yes, by preventing leaks in the return side from pulling unfiltered attic air into the system. Mountain cedar pollen (December-February) is among the most allergenic in North Texas, and standard 1-inch filters load quickly. When return ducts leak, the system draws air through those gaps instead of through the filter, introducing pollen directly. Sealing the return ductwork forces all intake air through the filtration media. We verify this with pressure testing after sealing. For homes with severe pollen sensitivity, we also quote Aprilaire whole-home media cleaners with MERV 13+ rating.
Three factors converge here: 1980s flex-duct with degraded inner liners and compressed insulation; 150-160°F attic temperatures that create extreme temperature differentials at connections; and clay-soil foundation movement that separates joints and creates low spots where condensation collects. Newer suburbs like Frisco or Flower Mound have tighter ductwork, better original insulation, and less foundation shift. The mold we find in Valley Ranch belly-sags is a direct result of standing water that sits for months - something our techs rarely encounter in post-2005 construction.
Uneven room temperatures, musty smells from supply registers, visible mold at registers, or airflow that has declined noticeably over time are repair indicators, not just cleaning triggers. If your Valley Ranch home was built 1983-1998 and still has original flex-duct, the probability of joint separation or belly-sag requiring repair is high regardless of how recently the ducts were cleaned. We perform camera inspection before quoting either service, and we show you the photo record before recommending repair versus cleaning. Call (469) 405-6133 to schedule.
