AfterTrusted Duct Repair & Sealing for Irving Homeowners
Duct repair and sealing in Irving typically costs $280-$890 depending on whether you’re sealing accessible leaks in a single system or replacing collapsed flex duct runs in an attic. Most jobs we handle in Las Colinas, Valley Ranch, and the Heritage District take three to six hours and are scheduled within a week, not months out. Call (682) 297-4068 and we’ll put a written price in your hand before any work starts.
We’ve been providing Duct Repair & Sealing - Irving since 2013. In that time we’ve documented the inside of 52,000+ duct systems with before-and-after photos, and we’ve learned what fails here specifically: the clay soils in north Irving shift foundations and crack rigid duct connections, while the attic heat in summer months degrades flex duct adhesive faster than in cooler parts of the metroplex. Our crews carry Nikro inspection cameras and Honeywell airflow meters on every truck. Every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews.
The Irving market has a specific problem with bait-and-switch duct cleaning and repair pricing. A competitor advertises a $79 “whole house special,” then discovers “unexpected” leaks that push the final bill past $1,200. We don’t operate that way. Haven Standard Clause 1 requires a written price before any work starts, every time, with no exceptions. The price we write is the price you pay.
What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps and separations in your supply and return plenum where conditioned air escapes into wall cavities, attics, or crawl spaces. In Irving, we commonly find 15-30% air loss in homes built between 2005 and 2015, when builders prioritized speed over seal quality during the construction boom. Our crews use a two-part approach: mastic sealant for permanent joints, backed by metal-backed tape rated for Texas attic temperatures. Every sealed joint is photographed and included in your Documented Photo Record.
Flex Duct Repair
Flex duct, the ribbed plastic tubing with fiberglass insulation that connects your main trunk to individual room registers, collapses, tears, or disconnects when attic heat degrades the adhesive or when pests access the space. In Irving’s older neighborhoods like Elm Fork and Plymouth Park, we regularly find flex duct that has sagged into a U-shape, trapping condensation and growing microbial contamination. We replace damaged sections with new R-8 insulated flex duct, support it with proper straps to prevent future sagging, and photograph every connection before the insulation jacket goes back on.
Metal Duct Repair
Galvanized steel ductwork, common in Irving homes built before 1990 and in higher-end custom construction, develops rust at seams, cracks at stress points, or complete separations where settling foundations have shifted the structure. The metal duct in a 1980s ranch near MacArthur Boulevard or a recent build in Twin Wells can both fail at the longitudinal seam where two pieces meet. We cut out damaged sections, fabricate replacement pieces on-site, and seal with mastic and mechanical fasteners rated for the pressure load of your specific system.
Duct Insulation
Insulation on ductwork prevents thermal loss as heated or cooled air travels through unconditioned spaces. In Irving, where attic temperatures exceed 140°F in July and August, missing or compressed insulation forces your HVAC system to overcome heat gain before the air even reaches your registers. We install new fiberglass duct wrap or replace damaged insulation on flex duct runs, with particular attention to the plenum connections where we most often find bare metal exposed. The improvement is measurable: we use a Honeywell digital thermometer to document supply air temperature before and after.
Mastic Sealant
Mastic is a thick, water-based sealant that remains flexible after curing, making it the preferred permanent sealant for duct joints in professional applications. Unlike duct tape, which degrades in attic heat within months, mastic lasts the life of the duct system when properly applied. Our crews brush mastic onto every joint, seam, and penetration in your accessible ductwork, then photograph the application for your job record. In Irving’s climate, we specify mastic rated for 250°F continuous exposure, well above typical attic peaks.
Air Leak Repair
Air leaks occur at connection points between duct components, at the register boot where duct meets wall or ceiling, and around the air handler cabinet itself. We pressurize your duct system and use a smoke pencil or theatrical fog to locate leaks that aren’t visible to inspection cameras alone. In a 2019 job near the Irving Convention Center, this method revealed a 4-inch separation behind a finished garage ceiling that was wasting an estimated 22% of the system’s output. We accessed the leak through a minimal opening, repaired it, and restored the ceiling finish.

Brands We Service for Duct Repair & Sealing
We’ve worked on duct systems connected to every major HVAC brand installed in Irving since 2013. Our crews regularly service ductwork paired with Honeywell air handlers and zoning controls, particularly in the smart-home builds near Las Colinas where Honeywell’s integrated systems are specified by builders. We stock common Honeywell plenum adapters and transition fittings, so repairs to connected ductwork don’t wait on parts.
We also maintain active familiarity with Aprilaire whole-home humidifiers and air cleaners, which integrate directly into return ductwork and require precise sealing to prevent bypass airflow. In the Flower Mound and Euless markets where Aprilaire media air cleaners are common, we’ve documented cases where an improperly sealed bypass damper was allowing unfiltered air to recirculate, defeating the purpose of the installation. Whether your system includes Aprilaire, Honeywell, or any other make, we can assess the duct integration and repair it to manufacturer specification.
BeforeAfterSigns You Need Duct Repair & Sealing Right Now
- Uneven temperatures from room to room. If your master bedroom in Irving runs 8°F warmer than the hallway in summer while the kitchen freezes, you likely have a disconnected or collapsed supply duct run. The conditioned air is going somewhere, just not where the thermostat expects it to go.
- Dust accumulation immediately after professional cleaning. You had your ducts cleaned last year, but the registers are filthy again within weeks. This often indicates a leak in the return side, pulling attic dust and insulation fibers into the airflow stream. Sealing the leak stops the contamination at its source.
- Utility bills that spike without usage changes. An Irving homeowner in Valley Ranch saw her summer electric bill jump from $340 to $520 between June and July with no thermostat adjustment. Our inspection found a separated flex duct in the attic dumping cooled air directly into the insulation. After repair, her August bill returned to $360.
- Whistling or rushing air sounds from walls or ceilings. Air moving through a gap the size of a quarter can produce audible noise, and that gap represents conditioned air you’re paying to heat or cool your framing. The sound is the symptom; the energy waste and potential moisture intrusion are the problems.
- Musty or chemical odors when the system runs. Leaks in the return duct can pull air from crawl spaces, wall cavities where pest control treatments were applied, or attics where roofing materials off-gas in heat. If the smell intensifies when the blower cycles on, the duct system is communicating with spaces it shouldn’t be.
Our Duct Repair & Sealing Process - Step by Step
- 1
System inspection with photo documentation. We start every job with a visual inspection of accessible ductwork using a Nikro inspection camera. The camera shows us the interior condition of each duct run, and we photograph what we find. These images become the “before” portion of your Documented Photo Record.
- 2
Pressure testing and leak identification. We seal the registers temporarily and pressurize the duct system to measure total leakage against the standard for your home’s square footage. For Irving homes, we reference the Texas Energy Code requirements and ASHRAE guidelines. A smoke pencil or theatrical fog reveals leak locations that visual inspection missed.
- 3
Written scope and price, delivered before work begins. Haven Standard Clause 1 requires it. We itemize each repair, list the materials we’ll use, and state the total price. You approve it in writing, or we leave and there’s no charge for the diagnosis. This is not an estimate that changes; it is the price.
- 4
Repair execution with process photography. Our technicians complete the agreed scope using the specified materials: mastic sealant, replacement flex duct, fabricated metal sections, or new insulation as required. We photograph critical steps during the work, not just before and after, so you can verify that sealed joints were actually sealed and replaced sections were actually replaced.
- 5
Post-repair verification and final documentation. We re-pressurize the system to confirm leakage reduction, measure supply air temperature at multiple registers using our Honeywell meter, and compile your complete job record: before photos, during photos, after photos, pressure test results, and the written 365-Day Done Right Promise. This record is delivered to you as a standard deliverable, not an extra.
How Much Does Duct Repair & Sealing Cost in Irving?
Duct sealing for a single system in an Irving home with accessible attic space typically runs $280-$450. This covers mastic sealing of all accessible joints, register boot sealing, and air handler cabinet sealing. Flex duct replacement, when one or two runs have collapsed or torn, generally falls in the $340-$620 range depending on the length and attic accessibility. More extensive metal duct repair or multiple flex duct replacements in larger homes can reach $680-$890.
Several factors move the price within these ranges. Attic accessibility is the largest: a truss attic with a walk board allows faster, safer work than a tight crawl space where every movement is constrained. The extent of damage matters; a single disconnected flex duct takes less time than a system where multiple runs have degraded. And the material type affects parts cost: galvanized steel fabrication requires more labor than flex duct replacement.
What should not affect the price is surprise. The $79 coupon model works by getting a technician into your home, then “discovering” problems that multiply the final bill. We reject this entirely. Our written price covers the agreed scope, and if we find something genuinely unexpected during the work, we stop, document it, and write a new price for your approval before continuing. No homeowner in Irving has received an invoice from CleanRun that exceeded their written approval.
Your free estimate includes the full inspection, pressure test, and written scope. There is no charge for the diagnosis, and no obligation to proceed.
