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 Suwanee
Duct repair and sealing in Suwanee typically costs $280-$650 for most residential jobs, with flex duct replacement running higher when attic runs have degraded past the point of sealing. We’re the Duct Repair & Sealing team at CleanRun, and we serve Suwanee from our Atlanta office - crews are on local roads daily, and most Suwanee appointments are scheduled within a few business days. Call (678) 904-9744 for a written estimate before any work starts.
Suwanee isn’t a generic suburb. The homes here - Laurel Springs, Olde Atlanta Club, Rivermoore, and the surrounding master-planned communities - were built fast during the late 1990s and 2000s, and the flex ductwork installed in those years is now reaching the age where it sags, disconnects, or traps debris in ways that rigid metal systems simply don’t. We see it on every camera inspection. The question isn’t whether your ducts have issues. It’s whether sealing will solve them or whether the flex has degraded too far to save.
Why CleanRun Air Duct Cleaning Sandy Springs Is Suwanee’s Preferred Duct Repair & Sealing Company
We’ve worked in Suwanee since 2013, and the pattern is consistent: large two-story homes with attic-mounted air handlers, long flex-duct runs to far bedrooms, and ductwork that has never been inspected with a camera. Our crews are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and every technician identifies by name before arrival.
Our reputation here is documented, not claimed. Every Suwanee job receives a written price before work begins - Haven Standard Clause 1 - and concludes with a Documented Photo Record of every duct run, delivered as part of the standard job record. Customers see what we found, what we did, and what the inside of their ducts look like after. No manager approval needed for the 365-Day Done Right Promise; it’s backed in writing on every job.
Scheduling is coordinated from our Atlanta office, but crews live and work in Gwinnett County. That matters when you’re trying to book around pollen season or after a summer where your second floor never cooled properly. We answer calls live, and we don’t use dispatch windows as a sales tactic.

Our Duct Repair & Sealing Services in Suwanee
Flex Duct Repair
Suwanee’s late-1990s and 2000s master-planned subdivisions were built with extensive flex duct runs through attic air handlers that routinely exceed 130°F, and that flex is now 20-30 years old. Every duct repair call here starts with deciding whether to clean or replace the duct rather than assuming a simple sealing job will fix airflow. We inspect with a camera, show you the sag points, kinks, or disconnections, and quote replacement only when sealing won’t hold. A typical flex duct repair or partial replacement in Suwanee runs $340-$720 depending on run length and attic access.
Mastic Sealant Application
Mastic is the only sealant we trust for metal-to-metal and metal-to-flex joints in Suwanee’s high-humidity attics. Tape dries and fails; mastic remains flexible. We apply it to plenum connections, trunk line seams, and register boots after source removal cleaning, then verify with a blower door test when indicated. Typical mastic sealing work in Suwanee ranges from $280 for targeted leak repair to $580 for full system sealing on larger homes.
Air Leak Repair
In Suwanee’s larger subdivision homes, the second-floor HVAC zone is almost always served by an attic air handler with long flex-duct runs to far bedrooms. Technicians regularly find that the flex has partially collapsed or disconnected at a boot, meaning conditioned air - and any contaminants - has been escaping into attic space for years rather than reaching the room. We repair the leak, seal with mastic, and document the before-and-after pressure readings. Air leak repair in Suwanee typically falls between $260 and $490.
Metal Duct Repair
Some Suwanee homes, particularly earlier builds and custom homes in Olde Atlanta Club, have galvanized steel trunk lines. We repair separated seams, corroded sections, and damaged take-offs using proper sheet-metal techniques and mastic finish. Metal repair is less common here than flex work, but when it’s needed, the labor is more intensive. Expect $380-$850 for metal duct repair in Suwanee.
Duct Insulation
When flex duct in Suwanee attics has degraded past its R-value or when condensation pools on uninsulated metal, we replace insulation with formaldehyde-free duct wrap rated for our humidity zone. This is often bundled with flex replacement rather than performed standalone. Combined insulation and flex work typically ranges $520-$940.

BeforeAfterTrusted Brands We Service in Suwanee
Our equipment roster includes Nikro negative-pressure extraction systems, Honeywell media air cleaners, and Aprilaire whole-home dehumidifiers - brands customers can look up independently before agreeing to a price. We stock common flex duct diameters, mastic, and connection hardware for Suwanee’s predominant system sizes, so most repairs don’t wait on parts. For specialized components, our Atlanta office maintains next-day supplier relationships with Abatement Technologies and Guardsman. The tool matters less than the documentation, but we name what we use so you can verify it.
Common Duct Repair & Sealing Problems We See in Suwanee Homes
- Construction dust and drywall debris from the 1995-2008 build boom remains trapped in supply and return ducts years after handover. Owners assume a new home is clean when it actually needs source removal before the first system balancing. We photograph this on every initial inspection.
- Flex duct runs sag, kink, or disconnect at attic boots, letting conditioned air escape into 130°F attics rather than reaching far bedrooms. This is a hidden failure that camera inspection alone reveals, and it’s endemic in Suwanee’s two-story subdivision homes with attic air handlers.
- Heavy spring tree pollen (oak, pine, cedar) plus summer dew points in the 70s loads filters and duct interiors fast. Any sagged flex that pools condensation becomes the mold colonization point that no amount of register-level cleaning fixes. We check for this specifically during Suwanee inspections.
- Second-floor temperature imbalance is almost always traced to duct leakage or collapse, not HVAC capacity. The bedroom at the end of the longest flex run - common in Laurel Springs and Rivermoore floor plans - suffers first.

In Laurel Springs, a homeowner called after our camera inspection showed our tech that the second-floor flex duct serving a far bedroom had disconnected at the boot, dumping conditioned air into the attic for years. We used mastic sealant and new flex connections to reattach the run, then applied source removal and HEPA filtration to clear the drywall dust that had settled inside the supply and return ducts since the home was built. A blower door test we ran before and after confirmed the leak was closed, and that bedroom finally held temperature on a 95°F July afternoon.

FAQs - Duct Repair & Sealing in Suwanee
Yes, and possibly more than a home built in the 1980s. Construction dust and drywall debris from Suwanee’s build boom often remains in ducts years after handover, and flex duct installed in 2004 is now 20 years into its typical 20-30 year service life. Call (678) 904-9744 for a camera inspection and written estimate - estimates are free.
Repair with mastic and new connections works when the flex is intact but leaking at joints; replacement is the better choice when the inner liner is torn, the insulation is water-damaged, or the sag is so severe that airflow is permanently restricted. We make this call with camera evidence, not assumptions, and we quote both options in writing when it’s close. Call (678) 904-9744 to schedule an inspection.
In Suwanee’s larger subdivision homes, the second-floor zone is almost always served by an attic air handler with long flex-duct runs to far bedrooms. Our camera inspections regularly find partially collapsed or disconnected flex at the boot, dumping conditioned air into 130°F attic space. Sealing or replacing that specific run usually fixes the temperature imbalance without touching the HVAC unit. Call (678) 904-9744 for a written diagnosis.
Yes. The Atlanta metro, including Suwanee, consistently ranks among the highest-pollen cities in the country, with tree pollen spiking to extreme levels each spring. Homes in Suwanee’s heavily wooded subdivisions draw this pollen through return air grilles, loading filters and lining duct interiors far faster than in less tree-dense areas. Any existing leak or sag accelerates the buildup. Call (678) 904-9744 to schedule post-pollen-season inspection and cleaning.
NADCA (National Air Duct Cleaners Association) sets the inspection, cleaning, and repair protocols we follow for source removal and system restoration. For Suwanee homeowners, this means our work meets a documented trade standard, not an internal checklist. Our equipment - including Nikro negative-pressure systems - is operated to NADCA guidelines, and our photo record shows compliance. Call (678) 904-9744 with specific questions about standards for your job.
