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.

AfterFast, Reliable Duct Repair & Sealing Across Rowlett
Duct repair and sealing in Rowlett typically runs $280-$650 for most residential jobs, with flex duct replacement and full-system mastic sealing at the higher end. CleanRun crews serve Rowlett from our Dallas-Fort Worth office, and we carry the specific flex duct sizes, mastic compounds, and insulation wraps most common in Rowlett’s 1980s-2000s housing stock. Call (469) 405-6133 for a written estimate before any work starts.
We’ve worked in Rowlett homes along Dalrock Road, near Waterview Drive, and throughout the Lakeshore Estates area. The housing here tells a split story: original suburban builds from the 1980s and 1990s with aging flex duct, and post-2015 rebuilds after the tornado that brought their own set of duct integrity problems. Both need attention, but for different reasons. Our Duct Repair & Sealing team documents what we find with photos and moisture readings so you can see exactly what your system needs.

Our Duct Repair & Sealing Services in Rowlett
Duct Sealing with Mastic Sealant
Rowlett’s combination of lake humidity and storm-era construction defects makes mastic sealing one of our most requested services. Mastic is a thick, fiber-reinforced compound we brush onto plenum joints, collar connections, and seams that have separated over time. Unlike foil tape, which degrades in Rowlett’s attic heat, mastic remains flexible and airtight for years. We apply it to every joint we disturb during repair work, and we often find unsealed plenum joints in post-2015 rebuilds where the 2016-2017 construction surge left shortcuts. The result is measured: we run a pressure test before and after, and the difference goes in your written job record.
Flex Duct Repair
Original flex duct in Rowlett’s 1980s and 1990s homes is now 25-40 years old. The inner liner cracks. The insulation compresses. The wire helix sags between supports, creating low spots where condensation pools. We replace damaged sections with new, properly supported flex duct sized to your system’s CFM requirements. In post-2015 rebuilds, we frequently find flex duct that was never properly seated at the collar - a gap that lets attic air, dust, and lake humidity bypass the filter entirely. We document the gap with photos, replace the section, and seat the collar correctly with a draw band and mastic.
Metal Duct Repair
Some Rowlett homes, particularly those built in the late 1990s and early 2000s, have galvanized steel trunk lines with flex duct branches. The metal itself rarely fails, but the seams pop, the dampers seize, and the takeoff connections to flex branches loosen. We reseal metal seams with mastic and fiberglass mesh, repair or replace damaged dampers, and reinforce takeoff connections. Metal work costs more than flex repair - typically $340-$650 in Rowlett - but it lasts decades when done right.
Duct Insulation Replacement
Insulation in Rowlett attacks takes a beating. The 2015 tornado drove rain into attics across the city. Lake Ray Hubbard humidity keeps attic moisture elevated even in homes that weren’t storm-damaged. Wet insulation clings to duct exteriors, compresses, and eventually harbors mold that the blower distributes through every register. We strip damaged insulation, treat the duct exterior if needed, and wrap with new fiberglass insulation of the correct R-value for North Texas attics. Every step is photographed. Moisture meter readings go in your job record.

BeforeAfterTrusted Brands We Service in Rowlett
Our equipment roster includes Rotobrush rotary cleaning systems, Nikro negative-air machines, Honeywell electronic air cleaners, and Aprilaire whole-home humidifiers and dehumidifiers. We don’t claim these brands make us better technicians; we name them so Rowlett homeowners can verify what we’re using and look up specifications independently. For duct repair and sealing specifically, we stock mastic compounds, flex duct, and insulation wraps matched to the sizes most common in Rowlett’s housing stock - 6-inch, 8-inch, and 10-inch flex, R-6 and R-8 insulation - so most repairs don’t wait on parts orders.
Common Duct Repair & Sealing Problems We See in Rowlett Homes
- Storm-era flex duct never properly seated at the plenum. In the frantic 2016-2017 rebuild surge after the 2015 tornado, crews worked fast. We regularly find post-2015 Rowlett homes where the flex duct collar was pushed onto the plenum takeoff but never secured with a draw band or sealed with mastic. The gap pulls unfiltered attic air - and lake humidity - directly into the system.
- Original 1980s-90s flex duct reaching end of life. The inner liner becomes brittle. Micro-tears let conditioned air leak into the attic. The wire helix rusts through at sag points. These systems weren’t designed to last 35 years, and in Rowlett’s heat and humidity, many haven’t.
- Water intrusion creating hidden mold reservoirs. Lake-area storms drive water through roof penetrations, soffit vents, and gable ends. Insulation soaks it up and holds it against the duct exterior. The homeowner smells nothing until the blower cycles on and pushes spore-laden air through every register. Our moisture meter finds what eyes can’t.
- Unsealed plenum joints in both old and new construction. The plenum - the big box on top of your air handler - connects to trunk lines and flex branches through sheet metal takeoffs. Every joint is a leak point if not sealed. We find this in 1990s builds and 2017 rebuilds alike. Mastic fixes it permanently.

We give you the full written price before any work starts - Haven Standard Clause 1 - and if we find something unexpected, we stop, show you the photo, and write a revised scope before continuing.

FAQs - Duct Repair & Sealing in Rowlett
It depends on what the camera inspection shows. If the interior of the duct is debris-laden but structurally intact - no standing water, no liner separation, no insulation saturation - negative-pressure extraction and sanitizing may be sufficient. If the camera shows standing moisture, collapsed flex duct, or mold growth on the interior liner, replacement is the only defensible option. We document both findings with photos and moisture meter readings so your insurer can see why we made the call. Call (469) 405-6133 and we’ll put a scope in writing.
Every CleanRun visit includes a Documented Photo Record - before, during, and after photos of every duct run, plus moisture meter readings, pressure test results, and a written scope of work. For insurance purposes, we note the specific damage mechanism: water intrusion path, storm date if known, construction defect identified. We were called to a lakeside home off Dalrock Road where a post-2015 rebuild had water intrusion in the attic after a storm, and our camera inspection found standing moisture inside a run of flex duct feeding the primary bedroom. The flex duct collar at the plenum was never properly seated during the 2016-17 rebuild surge, so we replaced that section, sealed the plenum joints with mastic, and re-insulated - documenting every step with before/after photos and a moisture meter reading for the homeowner’s insurance adjuster. That documentation package is standard on every job.
The 2016-2017 construction surge prioritized speed. We find improperly seated flex-duct collars, unsealed plenum joints, and missing insulation wraps in post-2015 rebuilds across Rowlett - defects that a 30-year-old home that was never damaged may not have. A “newer” house in Rowlett can have worse duct integrity than an older one. The only way to know is to look inside.
Yes. Rowlett’s position directly on the lake’s eastern shoreline pushes ambient humidity measurably higher than in inland DFW suburbs like Mesquite or Richardson. That humidity infiltrates duct systems through leaks and gaps, condenses on cool duct surfaces in summer, and accelerates microbial growth. Storm-era duct systems here face compounded contamination and moisture problems that neighboring cities don’t share in the same way. It’s not marketing hype; it’s what our moisture meter shows in Rowlett attics versus inland homes.
We arrive at the scheduled time, identified by name. We inspect your duct system with a camera, show you what we find, and write a scope and price before any work begins. Once approved, we perform the repair or sealing, test the system, and deliver your Documented Photo Record. The entire process is backed by our 365-Day Done Right Promise. Call (469) 405-6133 to schedule - estimates are free and written.
