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 Plano’s Preferred Duct Repair & Sealing Company
We’ve been in Plano homes since 2013, and the pattern is consistent: east Plano’s 1970s-1980s brick-veneer slab foundations shift with the seasons, and that movement finds its way into the attic. Our Duct Repair & Sealing team documents every finding with before-and-after photos of each duct run, delivered as part of the standard job record. Haven Standard Clause 1 requires a written price before any panel comes off, and we hold to that on every Plano visit.
Plano homeowners have left us a strong local reputation built on verifiable evidence, not marketing claims. The 365-Day Done Right Promise applies here exactly as it does everywhere we work: if the repair or sealing isn’t right, we make it right, backed in writing. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they’re identified by name before arrival. Calls to (469) 452-7766 are answered by a live person, 24/7.
What separates our Plano work from generic duct cleaning is local knowledge. We know that a register blowing attic dust in a 1983 home near Armstrong Elementary likely means a flex-duct boot pulled loose by clay soil heave, not a dirty duct. That diagnosis changes the scope and the price, and we put both in writing before starting.
Our Duct Repair & Sealing Services in Plano

Duct Sealing
Most Plano attics we enter have leaks at the plenum, at flex-duct connections, or where duct board meets the air handler. We seal with mastic sealant, not tape alone, because tape fails in 140°F attic heat. A typical duct sealing job in Plano runs $280-$450 for a single-zone system, with written pricing delivered before work begins. In west Plano and the Legacy corridor, two-story multi-zone systems have more connection points and may run $400-$650 to seal properly.

Flex Duct Repair
Flex duct is the weak link in Plano’s older housing stock. The original 1970s-1980s flex has a plastic jacket that becomes brittle after decades in unconditioned attics, and the fiberglass insulation underneath compresses or sheds. We replace crushed or torn flex sections under negative-pressure extraction with HEPA filtration running, using Guardsman-rated materials sized for the low-static systems common in east Plano tract homes. Flex duct repair in Plano typically runs $180-$340 per run, with full replacement of multiple runs in a system reaching $500-$850.

Metal Duct Repair
Some Plano homes, particularly custom builds in Willow Bend and areas west of Preston Road, have galvanized metal ductwork. Metal ducts don’t crush like flex, but their seams separate and their internal liners degrade. We repair separated seams with mechanical fasteners and mastic, and we replace rusted sections. Metal duct repair in Plano runs $320-$580 depending on accessibility and the extent of seam separation.

Duct Insulation
Plano’s summer attic heat makes uninsulated or degraded duct insulation a direct energy loss. We install new insulation wrap on repaired or sealed ducts, typically R-6 or R-8 fiberglass wrap depending on the application. Duct insulation in Plano adds $150-$300 to a sealing job when done together, and it’s often the difference between a sealed system and one that still sweats condensation into the attic.

Common Duct Repair & Sealing Problems We See in Plano Homes

- Flex-duct boots pulled loose by soil movement. On the Blackland Prairie clay soils underlying east Plano, seasonal heave and shrinkage flex slab foundations enough to pull flex-duct boots loose from registers and separate plenum connections. We routinely find attic dust and insulation fibers bypassing the filter entirely and entering living spaces through these disconnected joints.
- Fiberglass duct board liner shedding fibers. East Plano’s 35-45-year-old fiberglass duct board systems have liners that degrade under 140°F+ summer attic heat. The camera shows a white, fibrous buildup at elbows and transitions that isn’t dust, it’s degraded liner material being blown into the air stream.
- Plenum leaks in multi-zone two-story systems. West Plano and Legacy corridor homes from the 1990s-2000s have sprawling duct networks with more connection points. Plenum separation at the air handler leaks conditioned air into the attic and draws in outside humidity, creating condensation conditions that encourage mold colonization inside poorly insulated runs.
- Crushed flex runs from foot traffic or storage. Plano’s attic truss designs from the 1980s often leave flex duct draped across the bottom chord where homeowners or subsequent HVAC contractors step during service calls. A crushed flex run shows up as a room that won’t cool evenly, and the camera reveals a flattened section with compressed insulation.
Pricing for Duct Repair & Sealing in Plano, TX
We publish ranges because Haven Standard Clause 1 requires written pricing before work starts, and that starts with honest numbers.
| Service | Typical Range in Plano |
|---|---|
| Spot duct sealing (mastic, single zone) | $280-$450 |
| Flex duct repair / replacement (per run) | $180-$340 |
| Full flex-duct replacement (multiple runs) | $500-$850 |
| Metal duct seam repair | $320-$580 |
| Duct insulation (add-on to sealing) | $150-$300 |
| System reconnection + sealing (plenum, boots, multiple leaks) | $450-$780 |
What moves a Plano job toward the higher end: two-story multi-zone systems with more connection points, attic access limitations in older homes with tight scuttle holes, and the need for HEPA-contained negative-pressure work when degraded fiberglass duct board is involved. What keeps it lower: single-zone systems with accessible attics and localized leaks at visible joints. Every estimate is free, and every price is written before work begins. Call (469) 452-7766.

FAQs - Duct Repair & Sealing in Plano

East Plano’s 1970s-1980s slab homes sit on Blackland Prairie clay that heaves and shrinks seasonally, pulling flex-duct boots loose from registers and separating plenum connections. Cleaning a disconnected duct just moves debris around; the mechanical reconnection and sealing is what stops attic dust from entering the living space. We see this failure mode in Plano far more often than in neighboring cities on sandier or rockier substrates. Call (469) 452-7766 for a camera inspection and written scope.
Plano attics exceed 140°F routinely from June through September, and that heat accelerates the breakdown of fiberglass duct board liners and flex-duct plastic jackets. A 40-year-old flex duct in a Plano attic has endured roughly 500,000 hours of thermal cycling, far more than equivalent materials in cooler climates. The result is brittle jackets, compressed insulation, and liner material shedding into the air stream. We document this degradation with camera evidence before recommending repair or replacement. Call (469) 452-7766 for an assessment.
West Plano and Legacy corridor two-story homes from the 1990s-2000s have multi-zone duct networks with more connection points, and plenum separation at the air handler is the most common cause of attic dust entering living spaces. The leak draws unfiltered attic air into the return side, which then distributes through the supply registers. Our camera inspection locates the separation, and we re-secure the plenum with mastic sealant under negative-pressure containment. Typical repair runs $320-$520 for this failure mode in Plano. Call (469) 452-7766 for a written estimate.
Yes. Our repair and sealing protocols follow NADCA ACR, the Assessment, Cleaning, and Restoration standard, for containment, negative-pressure extraction, and post-repair verification. We document compliance with before-and-after photos of every duct run, delivered as part of the standard job record. The H.A.V.E.N. Standard adds written pricing before work starts and the 365-Day Done Right Promise after completion. Call (469) 452-7766 to review our protocol before scheduling.
Signs that point to repair rather than cleaning alone: rooms that won’t maintain temperature, visible attic dust at registers, musty odors that worsen when the system runs, or a recent spike in energy bills without thermostat changes. We start every Plano visit with a camera inspection of the duct runs, and we show you what we found before quoting either service. The written scope specifies whether sealing, repair, or cleaning is indicated, with line-item pricing for each. Call (469) 452-7766 to schedule.
We were called to a 1981 brick-veneer tract home near Armstrong Elementary in east Plano where the homeowner complained of attic-dust smell and a master-bedroom register that barely moved air. A camera inspection showed a crushed early flex run and a boot pulled loose from the register, with return-side leakage at the plenum; our tech reconnected the boot, re-secured the plenum with mastic sealant, and replaced the crushed flex section under negative pressure with HEPA filtration running. Post-repair static pressure dropped, and the homeowner noticed the room finally cooling evenly within the same afternoon.
