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 Cumming Is Suwanee’s Preferred Duct Repair & Sealing Company
We’ve worked Suwanee attics since 2013, and the patterns are unmistakable. The city’s building boom concentrated almost all residential construction between 1993 and 2008, which means flex-duct systems are failing on synchronized schedules across entire subdivisions. Homeowners in Suwanee know this - they’ve talked to neighbors with identical problems.
Our reputation here is built on documentation, not promises. Every job delivers a written price before the first panel comes off (Haven Standard Clause 1), a photo record of every duct run before and after, and the 365-Day Done Right Promise in writing. Technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they’re identified by name before arrival.
Scheduling is coordinated from our Atlanta office, with crews serving Suwanee locally. All calls route to a live person, 24/7. Bring any competitor’s written estimate - we provide a free second opinion, our number next to theirs, no obligation.
Our Duct Repair & Sealing Services in Suwanee
Flex Duct Repair
Suwanee’s flex-duct failures are unusually synchronized because so much of the city was framed in a single 1993-2008 window. Attic air handlers on blown-in insulation platforms have settled together, so we find the same kinked boots and separated collars across Laurel Springs and Olde Atlanta Club in the same season. We re-hang sagging runs with proper support straps, replace degraded inner liners, and re-mastic collars so airflow returns to manufacturer spec. We pulled a camera inspection on a two-story in Olde Atlanta Club where the upstairs wing had almost no airflow; the flex run had settled at the air-handler platform until it was nearly kinked at the collar, and the inner liner was shedding fiberglass into the supply. We re-hung the run with proper support, mastic-sealed the collar, wrapped the boot in duct insulation, and airflow to both back bedrooms came back to spec.
Mastic Sealant Application
Brush-on mastic outlasts tape in Suwanee’s 130-140°F summer attics by years. We apply Abatement Technologies mastic to every collar, seam, and penetration point, then verify seal integrity with a pressure test. The result is a documented, photographed seal that holds through Georgia’s thermal extremes. No foil tape shortcuts - mastic is the only sealant we warranty.
Duct Insulation
When flex-duct outer jackets degrade in Suwanee’s hot attics, supply air warms before it reaches the register and condensation forms on cool exterior surfaces. We wrap repaired runs with fresh insulation, seal the vapor barrier, and photograph the finished work. This matters especially in Suwanee’s older two-stories, where long attic runs mean more thermal loss per foot.
Metal Duct Repair
Some Suwanee homes - particularly custom builds near the Chattahoochee River corridor - use galvanized trunk lines with flex takeoffs. We patch corroded sections, re-seal trunk-to-plenum connections, and replace damaged dampers. Metal work requires different tooling than flex repair; our crews carry both.
Air Leak Repair
Leak detection starts with a pressure test of the entire duct system. We isolate the air handler, pressurize the ducts, and measure static loss against design spec. In Suwanee’s large homes - often 3,000-5,000 square feet - even small leaks across dozens of connections add up to significant energy loss. We mark every leak, repair with mastic or replacement components, and re-test to confirm.

Common Duct Repair & Sealing Problems We See in Suwanee Homes
- Blown-in insulation platforms let flex boots settle. In late-1990s Suwanee attics, these platforms compress unevenly over two decades. The flex run kinks or disconnects at the air-handler collar, starving whole wings of the house. Homeowners notice weak airflow to back bedrooms first.
- 130-140°F summer attic heat degrades flex collars and inner liners. Supply and return ducts leak warm, humid attic air that condenses inside runs. That moisture feeds microbial growth on fiberglass liner. The camera shows it before the homeowner smells it.
- Suwanee’s February-May pollen load packs return plenums and filters. Gwinnett County ranks among the highest-pollen metro areas in the country. Aging flex leaks pull that bioaerosol load straight into the airstream, accelerating debris buildup and aggravating allergies.
- Rural properties on Suwanee’s perimeter face extended cleaning intervals. Homes on unpaved roads or adjacent to open land see dust and pollen loading that interior suburban systems don’t. Wood heat in outbuildings or guest houses adds combustion particulate. These systems need inspection every 2-3 years, not the standard 3-5.
Pricing for Duct Repair & Sealing in Suwanee, GA
A typical flex-duct collar repair and re-hang in Suwanee runs $280-$420. Full flex-run replacement with new insulation wrap is usually $340-$580 per run. Mastic sealing of an entire attic duct system runs $680-$1,200 depending on the number of collars and seams. Metal trunk repair starts around $420 for accessible sections.
What moves the number: accessibility (tight attics take longer), the number of failed connections, and whether the air-handler platform needs re-support. We deliver a written price before any work starts - Haven Standard Clause 1 - and that price is flat per system, not per vent. You’ll receive before-and-after photos of every duct run as part of the standard job record. Call (678) 693-5322 for a written estimate at no charge.

FAQs - Duct Repair & Sealing in Suwanee
Every 3-5 years for standard suburban homes, every 2-3 years for properties on unpaved roads or with significant tree-canopy exposure. Suwanee’s dense pine and oak load, combined with 130-140°F attic heat accelerating flex degradation, means the inspection catches collar separation before it starves a wing of the house. Call (678) 693-5322 to schedule - estimates are free.
Weak or warm airflow from registers in specific rooms, often the back bedrooms on the second story. The thermostat runs longer to hit setpoint. Homeowners sometimes describe it as “the AC can’t keep up in July.” The cause is invisible from the living space - the camera finds the kink at the collar in the attic. We document it with a photo, repair with proper support and mastic seal, and re-test airflow at the register.
Yes, in most cases. Mastic sealing of collars and seams, plus targeted flex-run repair or replacement, restores system integrity without touching sound trunk lines. We pressure-test before and after to verify. The written scope names exactly which runs are sealed, which are replaced, and which are left intact - no blanket recommendations.
Gwinnett County’s pollen counts consistently rank among the nation’s highest, driven by dense pine, sweet gum, and oak canopy. Suwanee’s 1993-2008 housing stock uses aging flex duct with degraded seals, so return leaks pull that bioaerosol load directly into the system. The result is return plenums packed with debris and supply registers that need frequent cleaning. Proper sealing breaks that cycle.
Yes. All repair work follows NADCA assessment and cleaning standards, and our Nikro negative-pressure systems include HEPA filtration rated at 99.97% at 0.3 microns. We photograph filter condition before and after as part of the documented job record. The equipment roster is available for customer verification before any work starts.
