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 Roswell
Duct repair and sealing in Roswell typically runs $280-$680 per HVAC system for standard flex duct or metal duct repairs, with full multi-system homes in neighborhoods like Horseshoe Bend or Martins Landing often ranging $740-$1,850 depending on access conditions and the extent of original duct board deterioration. We dispatch to Roswell from our Atlanta office, and most repair visits are scheduled within two to three business days. Call (470) 516-9337 for a written estimate before any work starts.
We’ve worked in Roswell long enough to know the difference between a 1992 Edenwilde split-level with flex duct crumbling in a vented attic and a 2005 infill home with properly insulated metal trunk lines. The housing stock here is distinct. That matters when you’re pricing per system, not per vent, and when the homeowner needs to see proof of work they cannot physically reach themselves.
Why CleanRun Air Duct Cleaning Marietta Is Roswell’s Preferred Duct Repair & Sealing Company
Our Duct Repair & Sealing team has documented repair records from over 1,200 Roswell homes since 2013, many in the 30075 and 30076 zip codes. Roswell customers specifically mention our photo documentation in reviews, noting that seeing the inside of their duct runs before and after work convinced them the repair had actually happened. We do not ask anyone to trust us on description alone.
Scheduling is coordinated from our Atlanta office, and we route crews to Roswell daily. Technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and each arrives with a name badge and the job’s written scope already loaded on a tablet. No one walks in cold.
The 365-Day Done Right Promise applies to every Roswell job in writing, not as a verbal assurance. If a sealed joint fails or a replaced flex run separates, we return and make it right. That guarantee is backed by the H.A.V.E.N. Standard, which we publish and reference by clause number.
Our Duct Repair & Sealing Services in Roswell
Duct Sealing with Mastic Sealant
Roswell’s original 1985-1998 duct board systems were sealed at the joints with tape that degrades in attic heat. We remove failed tape, clean the collar, and apply mastic sealant, a water-based compound that cures to a flexible, permanent bond. In two- and three-system homes common in Martins Landing, we seal every accessible joint in the trunk line and plenum, the main distribution box connected to your air handler, then pressure-test the system to verify leakage reduction. One flat price per system, agreed before we open the first panel.
Flex Duct Repair
Flex duct, the insulated flexible tubing that feeds air from trunk lines to individual rooms, fails predictably in Roswell’s unconditioned attics. The plastic inner liner becomes brittle after 25-30 years, and the fiberglass insulation compresses where the duct sags. In Horseshoe Bend, our tech opened a crawl-space run and found the flex duct outer jacket separating from ground moisture wicking up from the Chattahoochee floodplain, with mold colonizing the inner liner; we removed that section, replaced it with insulated flex sized to the run, sealed the collar with mastic, and pulled a camera inspection before reconnecting the air handler. Every replacement is photographed. Every run is measured for static pressure after installation.
Metal Duct Repair
Some Roswell homes, particularly custom builds near the historic district, use galvanized steel trunk lines. These corrode at the seams where condensation collects, or where previous contractors have drilled test holes and failed to seal them. We patch metal with proper sheet-metal sleeves, seal with mastic, and insate any exposed sections. Metal work costs more than flex repair because it requires cutting, fitting, and riveting, but it lasts longer in humid attic conditions.
Duct Insulation Replacement
The original insulation wrapped around Roswell’s flex duct has often fallen to the attic floor or been shredded by rodents. We install new R-6 or R-8 insulation, depending on the attic’s temperature exposure, and secure it with mechanical fasteners rather than tape alone. In homes with three systems, this work multiplies, which is why we price per system, not per linear foot. The written scope specifies which runs get new insulation and which are intact enough to remain.

Our equipment roster includes Rotobrush for mechanical agitation inside duct runs, Nikro for negative-pressure extraction, and Abatement Technologies for HEPA filtration during repair work. We stock common flex duct diameters, mastic, and collar fittings locally, so most Roswell repairs are completed in a single visit without waiting on parts. Guardsman-treated insulation is available for homes with prior moisture damage. Customers can verify every brand independently; we name them specifically because the equipment matters as much as the technician operating it.
Common Duct Repair & Sealing Problems We See in Roswell Homes
- Original fiberglass duct board from the 1985-1998 building wave is at or past rated service life. The fiberglass liner inside the plenum and trunk lines deteriorates, shedding particles into the airflow. Sealing the exterior joints does not fix interior liner failure; the board must be replaced or encapsulated, and we document the condition with camera footage before recommending either.
- Two- or three-system homes with long flex runs through unconditioned attics develop multiple hidden leak points. Standard register-only cleaning misses disconnected joints buried under insulation. We inspect the full length of each run, not just the ends, and we photograph every disconnection we find.
- Crawl-space flex duct in Chattahoochee-adjacent subdivisions absorbs ground moisture. The outer jacket separates, and mold colonizes the inner liner. Surface cleaning cannot restore structural integrity; the duct must be removed and replaced. This failure mode is rare in drier, slab-on-grade subdivisions just a few miles north in Milton.
- Heavy pollen infiltration through return-air systems degrades filter performance and overloads the HVAC. Roswell’s mandated tree canopy, predominantly pine, oak, and sweet gum, drives seasonal pollen loads that undersized filters cannot capture. We check return duct sizing and seal leaks that bypass the filter entirely, pulling unfiltered attic or crawl-space air directly into the system.
Pricing for Duct Repair & Sealing in Roswell, GA
A typical single-system flex duct repair in Roswell runs $280-$480, including up to three replaced runs and mastic sealing of accessible joints. Metal duct repair on the same scale runs $340-$580. Multi-system homes, which dominate Roswell’s 2,500-4,500 square foot stock, are priced per system: two-system repairs typically fall between $540-$920, and three-system homes between $740-$1,250. Full duct board replacement, necessary when the original fiberglass liner has failed, ranges $1,200-$1,850 per system depending on plenum access and attic clearance.
What moves the price: attic accessibility (blown insulation adds labor time), the number of disconnected or damaged runs, whether the plenum itself needs replacement, and whether we find moisture damage requiring insulation replacement. We deliver a written price before any work starts, every time, under Haven Standard Clause 1. No per-vent pricing. No coupon bait. Call (470) 516-9337 for an exact quote on your Roswell home, estimates are free.

FAQs - Duct Repair & Sealing in Roswell
Yes, we price per system, not per vent, because each system has its own plenum, trunk line, and set of flex runs. A three-system Martins Landing home typically ranges $740-$1,250 for standard repairs, compared to $280-$480 for a single system. The written scope breaks out each system separately so you see exactly what each costs before work begins. Call (470) 516-9337 for an exact quote on your home.
It depends on the interior liner condition, which we determine with a camera inspection. If the fiberglass liner is intact, we can seal exterior joints with mastic and encapsulate minor surface wear. If the liner is shedding or delaminated, sealing the outside does not stop particle release, and we recommend replacement. We show you the camera footage and explain which condition yours is in before you decide. Call (470) 516-9337 to schedule an inspection.
Yes. The river corridor elevates Roswell’s relative humidity compared to inland northern suburbs, and that moisture accumulates in unconditioned attics and crawl spaces. We regularly find flex duct outer jackets separating from absorbed moisture in Chattahoochee-adjacent subdivisions like Horseshoe Bend, with mold colonization that requires replacement rather than repair. This pattern is rare in drier, slab-on-grade areas just a few miles north. Call (470) 516-9337 if you suspect moisture damage in your ductwork.
Every CleanRun job includes a Documented Photo Record: before-and-after images of the inside of every duct run we touch, delivered as part of your standard job record. You see the disconnected joint, the deteriorated liner, or the separated flex jacket before work starts, and the sealed, replaced, or repaired condition after. This practice has been standard on every job since 2013. No other documentation method exists in our workflow. Call (470) 516-9337 and ask to see sample photo records from previous Roswell jobs.
Pollen itself does not clog ducts, but it overloads filters and forces the system to pull harder, which draws unfiltered air through leaks in the return duct. Roswell’s city-mandated tree canopy produces some of the highest pollen loads in the Atlanta metro, and homes with undersized filters or leaky return plenums suffer the most. Sealing return-side leaks ensures all intake air passes through the filter first. We inspect return duct integrity as part of every repair scope. Call (470) 516-9337 for a return-duct evaluation.
