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.

Why CleanRun Air Duct Cleaning Plano Is Garland’s Preferred Duct Repair & Sealing Company
We’ve been serving Garland since 2013, and the pattern is consistent: homes built during the 1960s, 70s, and 80s east of Bush Turnpike hold ductwork that was never designed to last this long. Our Duct Repair & Sealing crews know the difference between a quick collar reset and a full run replacement because they’ve documented thousands of them. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we publish our license number on every estimate.
Garland homeowners don’t book us for speed. They book us because we photograph every duct run before and after, deliver the images as part of the standard job record, and back the work with the 365-Day Done Right Promise in writing. If it’s not right, we make it right. Not a policy. A clause.
Our response time to Garland is same-day or next-day for most repair calls, and scheduling is coordinated from our DFW office without the runaround of a national dispatch center. You speak to a live person when you call, and the technician who arrives is identified by name before they pull into your driveway.
Our Duct Repair & Sealing Services in Garland

Duct Sealing
Garland’s original sheet-metal duct systems were sealed with fabric tape and paste that degrades after four decades of North Texas heat cycles. We seal with mastic sealant, a water-based compound that remains flexible and is rated for the temperature swings these attics see. On a recent job near Firewheel Town Center, we measured 34% air loss through degraded seals before application and 4% after. The homeowner received before-and-after photos of every joint, plus the written scope under Haven Standard Clause 1.

Flex Duct Repair
Flex duct is common in Garland additions and retrofits, and it’s the first thing to fail when Blackland Prairie clay shifts a slab. We replace crushed or disconnected flex runs with properly sized new material, secure collars with mechanical fasteners plus mastic, and support the run to prevent sagging. Our crews carry Rotobrush and Nikro equipment for the cleaning that should accompany any flex repair, so loosened debris doesn’t circulate through your newly sealed system.

Metal Duct Repair
Original rigid ducts in Garland’s 1958-1985 housing stock often carry degraded fiberglass interior liner that sheds particulate directly into the airstream. Register-only vacuuming misses it entirely. We repair separated seams, replace rusted sections, and when liner degradation is advanced, we recommend full replacement with modern galvanized metal. Every repair is photographed, and the photo record is delivered to you before we leave.

Duct Insulation
Uninsulated or degraded-insulation duct runs in Garland attics lose conditioned air to 140-degree summer temperatures and sweat during humidity spikes. We install foil-faced fiberglass insulation with proper vapor barriers, sealed at all seams. This is particularly critical on supply runs near the Plenum in older homes where the original insulation has compressed to nothing.

Mastic Sealant Application
We apply mastic by brush and spray depending on access, and we verify seal integrity with pressure testing where appropriate. Mastic outlasts tape by decades and is the standard we apply on every Garland sealing job, no exceptions.

Air Leak Repair
Disconnected ducts don’t just waste money. In Garland’s older homes, they pull attic insulation debris, rodent droppings, and pollen directly into the living space. We locate leaks with camera inspection and pressure testing, then repair with materials matched to the original system.

Common Duct Repair & Sealing Problems We See in Garland Homes

- Clay-shifted slab homes pulling flex collars off plenums. On a slab ranch off Saturn Road in east Garland, our tech ran a camera inspection and found the flex collar pulled clean off the plenum where clay movement had shifted the slab - the run was dumping conditioned air and attic insulation debris straight into the attic instead of the living room. We reset and mastic-sealed the collar, replaced a crushed low-clearance section with rigid metal, then cleaned supply and return ducts under negative pressure with HEPA filtration. The homeowner’s rear rooms finally held temperature, and the register airflow jumped measurably.
- Degraded fiberglass liner in original metal ducts shedding particulate. The bulk of Garland’s single-family housing was built between roughly 1958 and 1985 as tract developments on slab foundations, and many retain original rigid sheet-metal ductwork with degraded fiberglass interior liner. This liner doesn’t just collect dust; it breaks down and distributes fibers into the airstream. Register-only vacuuming misses it, and the liner keeps failing until it’s addressed.
- Crushed low-clearance attic runs in dense east Garland housing. These neighborhoods were built with minimal attic height, and decades of maintenance traffic has compressed or kinked duct runs that now restrict airflow by 30% or more. Replacement with properly routed rigid metal often restores capacity without the space requirements of original flex installations.
- Shared dryer vent stacks in apartment and condo buildings accumulating lint beyond unit-level reach. Garland’s denser housing near Garland Avenue and I-635 includes multi-family buildings where individual dryer vents feed common stacks. A unit-level clean never reaches the common run where lint accumulates and creates fire risk. We coordinate with property management for full-stack inspection and cleaning under the H.A.V.E.N. Standard.
Pricing for Duct Repair & Sealing in Garland, TX
A typical flex duct collar reset and mastic seal in Garland runs $280-$420. Full section replacement with rigid metal on a crushed low-clearance run: $550-$750. Whole-system resealing with mastic on a 1,800-square-foot home with original 1970s ductwork: $900-$1,400. Duct insulation replacement on exposed attic runs: $400-$650 per run depending on linear footage and access.
What moves the number: accessibility (crawl space versus walk-in attic), material type (flex versus rigid metal), and whether we’re repairing one failed section or addressing systemic degradation. We don’t do per-vent pricing. We don’t do $79 coupons that become $800 invoices. One flat price per system, agreed in writing before work starts, every time. Free estimates.

FAQs - Duct Repair & Sealing in Garland

You likely need both, and the order matters. Homes from this era in Garland typically have original ductwork with degraded seals, possible flex collar separation from slab movement, and fiberglass liner breakdown that cleaning alone won’t fix. We camera-inspect first, show you what we found, and quote repair and cleaning as separate line items with a written total before work starts. Call (469) 452-7766 for an exact scope - estimates are free.
Multi-family buildings in Garland often share duct chases or dryer vent stacks between units, so a repair or cleaning in one unit can affect airflow or safety in others. We coordinate with property management, document common-area conditions with photo records, and scope work to address both individual unit needs and shared system integrity. Single-family homes don’t carry this coordination requirement. Call (469) 452-7766 to discuss your building type.
Yes. The Blackland Prairie’s highly expansive black clay shifts seasonally with moisture changes, and 40-60 years of this movement routinely separates flex duct collars from plenums or crushes low-clearance runs in Garland’s 1958-1985 slab tract homes. This is not theoretical; we document it regularly in east Garland neighborhoods where the original slab has had decades to move. The repair is straightforward once located: reset, seal, and sometimes replace the damaged section with rigid metal. Call (469) 452-7766 if you suspect a disconnect.
We remove degraded original tape and paste, clean joint surfaces, apply mastic sealant by brush or spray, and mechanically secure flex collars where present. On rigid metal, we inspect for liner degradation that would make sealing pointless without section replacement. Every sealed joint is photographed, and we pressure-test or airflow-test where access allows. The work is backed by the 365-Day Done Right Promise. Call (469) 452-7766 for a written quote on your specific system.
Yes. Garland’s central AC runs six or more months annually, continuously pulling mountain cedar, elm, and oak pollen through the system. Combined with summer humidity that condenses on uninsulated duct sections, this accelerates both particulate accumulation and microbial growth inside aging ductwork. Homes with original 1960s-1980s systems typically need more frequent inspection and more aggressive repair than newer construction. We don’t sell maintenance contracts; we document what we find and let you decide. Call (469) 452-7766 to schedule camera inspection.
