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 runs $280-$680 for most homes, with flex duct boot reattachment and mastic sealing being the most common scope we write up. Our crews are dispatched from the Atlanta office and carry the full Rotobrush and Nikro inventory needed for Suwanee’s builder-grade flex duct systems. Call (470) 326-1926 and we’ll put a written price in front of you before any panel comes off.
We’ve worked Suwanee long enough to know the subdivisions by their duct configurations. Olde Atlanta Club, Laurel Springs, Rivermoore Park - these aren’t just neighborhood names to our technicians. They’re the same 1995-2008 production builds with the same flex duct runs through the same hot attics, failing in the same predictable ways. That pattern recognition matters. It means we show up knowing where to look first.
Why CleanRun Air Duct Cleaning Johns Creek Is Suwanee’s Preferred Duct Repair & Sealing Company
Our reputation in Suwanee was built on documentation, not door hangers. Every job since 2013 has started with a written price and ended with a photo record of every duct run, before and after. Suwanee homeowners research before they call, and they stay with us because the evidence is in their inbox, not our marketing.
Response time to Suwanee is same-day or next-day for standard scheduling. Calls are answered by a live person, 24/7, and our background-checked, uniformed technicians are identified by name before arrival under Haven Standard Clause 3: Verified Crews. No surprises at the door.
Local knowledge shapes every estimate. We know that a “cleaning” call from a home off Suwanee Dam Road or Peachtree Industrial Boulevard often turns into a repair scope once the camera hits the attic. The plastic collars on flex duct boots in these subdivisions have been shrinking through Georgia heat cycles for 20-plus years. We price for what we find, not what we hope.
The 365-Day Done Right Promise applies to every Suwanee job in writing. If the work isn’t right, we make it right. Not a policy subject to manager approval. A written guarantee, backed by the H.A.V.E.N. Standard.
Our Duct Repair & Sealing Services in Suwanee
Flex Duct Repair
This is the work we do most in Suwanee. The large two-story homes in master-planned communities were built with extensive flex-duct runs through unconditioned attics - thin-walled duct that degrades faster in Georgia’s attic heat than the metal trunk-and-branch systems found in older Atlanta neighborhoods. We replace collapsed sections, reattach separated boots, and reinforce sagging runs with proper support straps. Every repair is photographed before and after, and the photo record is delivered as part of your standard job documentation.
Mastic Sealant Application
Mastic is the only sealant we use on duct joints in Suwanee attics. Tape dries and fails; mastic remains flexible and seals against the pressure pulses that flex duct experiences every time your multi-zone system cycles. We brush mastic onto every joint, collar, and penetration, then photograph the application. In Suwanee’s humidity, this matters more than in drier climates - poorly sealed joints draw attic air laden with pollen and moisture, creating condensation points where mold takes hold.
Air Leak Repair
Air leaks in Suwanee homes aren’t minor efficiency losses. They’re the reason bedrooms over the garage never cool and utility bills spike in July. We pressurize the system, locate leaks with smoke and digital manometers, then repair with mechanical fastening plus mastic. The static pressure readings at your air handler tell us whether we’ve sealed the envelope - we document the before and after numbers in writing.
Duct Insulation
When flex duct runs through a Suwanee attic, the 130°F summer temperatures cook the air inside before it reaches your register. We wrap exposed or degraded insulation with foil-backed fiberglass, sealed at every seam with matching tape. This is common in Rivermoore Park homes where original insulation has compressed or been disturbed by wildlife. The work is photographed, and the R-value of the replacement material is noted on your written scope.
Metal Duct Repair
Less common in Suwanee’s 1995-2008 housing stock, but present in some custom builds and additions. We repair separated seams, replace corroded sections, and seal with mastic or specialized metal duct sealant depending on the application. Our crews carry the tools and fittings to fabricate transitions on site.
Duct Sealing
Whole-system duct sealing for Suwanee homes with multiple zones and long attic runs. We seal from the plenum - the main distribution box at your air handler - through every branch to the register boot. The goal is measured: reduced static pressure loss, balanced airflow at registers, and documented temperature differential improvement. We don’t guess. We measure, seal, and measure again.

Our trucks stock parts and equipment from Honeywell, Aprilaire, and Rotobrush - brands our Suwanee customers can verify independently before agreeing to any scope. We don’t use proprietary or unlabeled components. When a zone damper fails in a Laurel Springs home or an Aprilaire media filter housing cracks in Olde Atlanta Club, we replace with like-for-like or better, and the part number goes on your written invoice. Fast turnaround because we carry inventory, not because we rush.
Common Duct Repair & Sealing Problems We See in Suwanee Homes
- Flex duct boots pulling away from upstairs ceiling registers. The plastic collars shrink through 20-plus years of Georgia attic heat cycles. A bedroom in Rivermoore Park can be drawing 130°F attic air instead of conditioned supply, and the homeowner only notices because the room “never cools right.” Camera inspection finds the gap every time.
- Sagging flex duct with gaps at joints. Builder-grade support straps fail in hot attics, letting duct sections sag and separate. Conditioned air leaks into the attic, humidity infiltrates the system, and energy bills climb without explanation. We find this behind finished walls and in tight chases where a standard cleaning never looks.
- Condensation-driven mold at poorly sealed joints. Suwanee’s combination of high summer humidity and pollen-laden return air creates perfect conditions for mold growth at duct connections. Post-summer inspections regularly show black or gray growth at the first elbow after the plenum. We clean, seal with mastic, and document.
- Partially collapsed duct sections in multi-zone systems. The large two-story homes common in Suwanee have complex zone configurations with ductwork hidden behind drywall. A section collapses, the zone damper compensates, and the homeowner blames the thermostat. Camera inspection through the return reveals the real problem.
Pricing for Duct Repair & Sealing in Suwanee, GA
Typical duct repair and sealing in Suwanee runs $280-$680 for single-zone flex duct work, with most Olde Atlanta Club and Laurel Springs homes falling in the $340-$520 range for standard boot reattachment, mastic sealing, and insulation wrap. Multi-zone homes with longer attic runs or concealed access issues can reach $780-$1,200. Metal duct repair, when needed, starts around $420 for accessible sections.
What moves the number: accessibility of the attic scuttle or hatch, length of flex run to be replaced or supported, whether the repair requires moving insulation to reach concealed joints, and whether zone damper adjustment is needed after sealing. We price by the scope, not by the vent. One flat price per system, agreed in writing before work starts, under Haven Standard Clause 1.

FAQs - Duct Repair & Sealing in Suwanee
These subdivisions were built during the 1995-2008 production boom with thin-walled flex duct through unconditioned attics, and that duct is now hitting the 20-30-year failure window. The plastic collars shrink, boots detach, and sections sag or collapse. A cleaning brushes debris from intact duct; it doesn’t reattach a separated boot or seal a gap that’s pulling 130°F attic air. Our Duct Repair & Sealing team finds that roughly half of Suwanee “cleaning” calls need repair scope added once the camera goes in. Call (470) 326-1926 for an exact quote - estimates are free.
Gwinnett County sits in one of the highest seasonal pollen-load corridors in the US, with heavy pine, oak, and sweet gum events each spring. In Suwanee’s large open-plan great rooms, return-air systems pull that pollen through every gap in the duct envelope. Once inside, it accumulates at elbows and behind filters, and the organic material supports mold growth when summer humidity hits. Sealed ductwork keeps pollen in the filter path, where it belongs. We inspect post-summer for condensation and mold at joints that were leaking in spring. Call (470) 326-1926 for an exact quote - estimates are free.
Yes, though the scope differs. Shared HVAC systems in Suwanee multi-family buildings typically have main trunk lines with individual take-offs to each unit. We can seal and repair from the unit-side access points, and we coordinate with building management for any main-line work that affects multiple residents. Our written scope defines exactly what is unit-side versus common-area, so there’s no confusion about responsibility. Haven Standard Clause 1 applies: price in writing before work starts. Call (470) 326-1926 for an exact quote - estimates are free.
The upstairs bedroom or bonus room “never cools right” despite the thermostat reading normal. Homeowners describe dust accumulation on the register fins, a slight temperature difference between rooms, or a faint attic odor when the system runs. In Olde Atlanta Club, we found a boot completely separated from its collar - the room had been drawing unconditioned attic air for years. Camera inspection confirms it in minutes. Call (470) 326-1926 for an exact quote - estimates are free.
Suwanee’s 1995-2008 homes use flex duct, not metal trunk-and-branch. The sealing challenge is joint integrity at boots and splices, not seam corrosion or separated elbows. Attic access is typically through a scuttle in the upstairs hallway, and the duct runs are longer and more convoluted to reach distant second-floor registers. We use mastic on every joint, support straps every four feet, and foil-backed insulation on exposed runs. The photo record shows the difference between our work and tape-only repairs that fail in two seasons. Call (470) 326-1926 for an exact quote - estimates are free.
