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.
Fast, Reliable Duct Repair & Sealing Across Carrollton
Duct repair and sealing in Carrollton typically costs $280-$750 for most homes, with full duct board replacement running $1,200-$2,400 when delamination or structural failure is found. We dispatch crews to Carrollton from our Dallas-Fort Worth coordination office, and most Carrollton appointments are scheduled within 2-4 business days. Call (682) 297-4068 for a written estimate before any work starts.
We’ve worked Carrollton’s neighborhoods long enough to know what the housing stock hides. The homes along Josey Lane, the subdivisions near Hebron Parkway, the ranch-style builds around Marsh Lane - most were built between 1975 and 1995 with fiberglass duct board trunks and flex branch runs that have now spent three to four decades in 130°F attics. Our Duct Repair & Sealing team doesn’t quote cleaning without first running a camera. Too often, what looks like a standard job reveals separated flex connections, collapsed inner liners, or duct board delamination that changes the scope entirely.
Why CleanRun Air Duct Cleaning Irving Is Carrollton’s Preferred Duct Repair & Sealing Company
CleanRun has served the Carrollton market since 2013, completing jobs with a written price delivered before work begins and a Documented Photo Record delivered after. We’ve photographed the inside of over 52,000 homes’ duct systems, and Carrollton’s older stock produces some of the most instructive before-and-after comparisons we have on file.
Our crews know the local failure patterns. Foundation movement from Blackland Prairie expansive clay is not abstract geology here - it’s the reason we carry extra mastic sealant and collar clamps on every Carrollton truck. Techs working the 75007 and 75010 ZIP codes regularly find flex duct pulled loose at supply boots, a condition that wastes conditioned air into attic spaces and drives summer electric bills upward.
Every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise applies to every Carrollton job in writing, not as a verbal courtesy. And we publish our license number on every page because credentials should be verifiable, not buried.
Our Dallas-Fort Worth office coordinates scheduling for Carrollton homeowners, with most repair and sealing appointments available within 2-4 business days. We don’t manufacture urgency. We show up when we say we will, document what we find, and put the price in writing before touching a single panel.
Our Duct Repair & Sealing Services in Carrollton

Duct Sealing
Sealing is often the most cost-effective intervention in Carrollton homes, and the most frequently overlooked. We apply mastic sealant - a thick, fiber-reinforced compound that remains flexible after curing - to all accessible joints, plenum connections, and register boots. In Carrollton’s 1980s-era homes, we regularly find that original duct tape has dried to dust, leaving gaps that leak 20-30% of conditioned air into attics and wall cavities. Our sealing work is photographed before and after, with airflow measurements taken at key registers to verify improvement. A typical whole-system sealing in Carrollton runs $280-$450 for accessible ductwork.

Flex Duct Repair
Flex duct, the insulated flexible tubing that carries air from trunk lines to individual rooms, fails predictably in Carrollton’s conditions. The inner plastic liner becomes brittle after years of 130°F attic exposure, and the wire helix can collapse or separate at connection collars. Add Blackland Prairie clay soil movement, and you get the separated joints we find near Josey Lane and throughout the 75007 corridor. We replace compromised flex runs with new R-6 or R-8 insulated duct, secure with mechanical fasteners and mastic, and re-insulate any disturbed sections. Single flex run replacement in Carrollton typically runs $180-$340; multiple runs or hard-to-access attic routing pushes toward $500-$750.

Metal Duct Repair
Older Carrollton homes with galvanized steel trunk lines - less common but present in some 1970s builds - develop rust at seams and separations at slip joints. We cut out corroded sections, fabricate replacement pieces, and seal with mastic and foil tape rated for HVAC use. Where metal trunks connect to newer flex branches, the transition points require particular attention; thermal expansion at these junctions works fasteners loose over decades. Metal duct repair in Carrollton ranges $320-$580 depending on accessibility and extent of corrosion.

Duct Insulation
Compromised insulation on flex duct or trunk lines forces your air handler to work harder against attic heat gain. In Carrollton, where cooling runs six months of the year, this penalty adds up. We replace damaged insulation with fresh fiberglass wrap or closed-cell foam where appropriate, sealed with vapor-barrier jacketing. Re-insulation is often bundled with flex duct repair or sealing work; standalone attic duct re-insulation in Carrollton runs $400-$680 for typical single-system homes.

Common Duct Repair & Sealing Problems We See in Carrollton Homes

- Delaminated fiberglass duct board inner liners. The 1980s-era homes common along Carrollton’s Josey Lane corridor were built with fiberglass duct board trunks whose inner foil liners separate after decades of thermal cycling. Once delaminated, the exposed fiberglass releases fibers into airflow and cannot be cleaned - only encapsulated or replaced. We inspect for this condition before quoting any cleaning price.
- Flex duct connections separated by foundation movement. Carrollton’s Blackland Prairie expansive clay swells and shrinks with moisture changes, stressing slab foundations and the ductwork routed through attics above them. Supply boots and return plenum connections pull apart, creating hidden air loss that standard cleaning won’t address. Our crews carry the mastic and mechanical fasteners to reseat these joints properly.
- Collapsed or separated flex duct inner liners from attic heat degradation. Attic temperatures exceeding 130°F soften the adhesives bonding flex duct’s inner plastic liner to its wire helix. Over years, the liner sags, collapses, or detaches entirely - restricting airflow to specific rooms and forcing the system to overcompensate. We replace these runs with new flex duct rated for the thermal stress.
- Dried, failed original duct tape at all joints. The tape applied when Carrollton’s homes were built has long since hardened and lost adhesion. Every joint, every boot, every plenum connection becomes a leak point. Mastic sealant is the correct repair, applied after mechanical fastening, and it lasts.
Pricing for Duct Repair & Sealing in Carrollton, TX

FAQs - Duct Repair & Sealing in Carrollton

Because Carrollton’s 1975-1995 housing stock frequently contains duct board and flex duct that has degraded past the point where cleaning is safe or effective. Our camera inspection identifies delaminated liners, separated joints, and collapsed flex before we commit to a scope of work. Call (682) 297-4068 and we’ll schedule the inspection at no charge - the written price follows, and you decide whether to proceed.
Blackland Prairie expansive clay beneath Carrollton swells when wet and shrinks when dry, producing ongoing foundation movement that pulls flex duct connections apart at supply boots and return plenums. This creates hidden air loss and pressure imbalances that cleaning alone cannot fix. We see this condition more frequently in Carrollton than in neighboring cities on sandier or more stable soils. The repair requires reseating connections with mechanical fasteners and mastic, not just vacuuming debris.
It means the inner foil liner of your fiberglass duct board trunk line has separated from the fiberglass core, exposing raw glass fibers to the airflow stream. This is common in Carrollton’s 1980s-era homes and cannot be cleaned - the fibers will continue releasing. The correct repair is either encapsulation with a specialized coating or full trunk replacement, depending on extent. We photograph the condition, explain the options, and put both scope and price in writing before any work begins.
Most sealing and flex duct repair jobs in Carrollton are completed in 3-5 hours. Full duct board trunk replacement extends to a full day. We schedule with a realistic time window and update you if inspection reveals conditions that change the scope. The 365-Day Done Right Promise covers all work regardless of duration.
Sealing reduces the infiltration of attic dust, pollen, and insulation particles into duct systems - a significant factor in Carrollton, where heavy spring cedar, oak, and ragweed pollen loads get pulled deep into HVAC systems during six months of near-continuous cooling operation. Sealed ducts also prevent pressure imbalances that draw unfiltered air through wall cavities. For homeowners with allergy sensitivity, we often recommend sealing in combination with filtration upgrades using Honeywell or Aprilaire media. Call (682) 297-4068 to discuss whether your duct condition makes sealing the right first step.
Our crew was recently called to a 1988-built home near Josey Lane where the homeowner complained of dust blowing from the registers and high summer electric bills. Using camera inspection and agitation tools, we found the fiberglass duct board trunk line had a delaminated inner liner releasing glass fibers, and two flex runs had separated at the collars due to foundation movement. We performed source removal with negative pressure and HEPA filtration, then sealed the separated joints with mastic sealant and re-insulated the compromised sections, restoring proper airflow and eliminating the fiber release.
