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.
Fast, Reliable Duct Repair & Sealing Across Sandy Springs
Duct repair and sealing in Sandy Springs typically costs $280-$680 for a whole-home job, with most ranch and split-level homes completed in a single day. CleanRun’s crews work the older neighborhoods off Hammond Drive and Roswell Road regularly, and we dispatch from our Atlanta office with Sandy Springs-specific parts already on the truck. Call (678) 904-9744 for a written estimate before any work starts.
We’ve been in enough Sandy Springs attics to know what we’re going to find before the ladder goes up. Original fiberglass duct board from 1975 doesn’t announce itself until the panel comes off and the camera goes in. That’s why our Duct Repair & Sealing team carries mastic sealant, flex duct repair stock, and the documentation gear to photograph every run before we touch it and after we’re done. Haven Standard Clause 1 means you get the price in writing first. Every time.
Why CleanRun Air Duct Cleaning Sandy Springs Is Sandy Springs’s Preferred Duct Repair & Sealing Company
CleanRun has served more than 52,000 homes since 2013, and a significant share of those jobs have been in the Fulton County corridor that became Sandy Springs. Homeowners here tend to research before they call, and they stay for the documentation. Our Google and BBB profiles show the pattern: Sandy Springs customers specifically mention the photo records and the written price in their reviews. They looked at the $79 coupon companies and chose the crew that shows them what was actually inside their ducts.
Response time to Sandy Springs neighborhoods is typically same-week, with scheduling coordinated from our Atlanta office. We know the difference between a 1968 ranch near the Chattahoochee and a 2015 build in the Perimeter Center corridor, and we stock accordingly. Older homes need flex duct repair and mastic work; newer construction more often needs register sealing and pressure balancing. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they’re identified by name before arrival.
The 365-Day Done Right Promise applies here exactly as it does everywhere we work. Written, not whispered. If the seal doesn’t hold or the repair fails, we make it right. No manager approval required.
Our Duct Repair & Sealing Services in Sandy Springs

Duct Sealing
Most Sandy Springs homes we test with a duct blaster leak 20-35% of their conditioned air into the attic or crawl space. In the ranch homes near North Springs and the neighborhoods threading toward the Chattahoochee, that leakage often traces to original register boots that were never properly sealed to the drywall, or to duct board joints where the factory tape has dried and curled. Our duct sealing protocol uses mastic sealant on every accessible joint, register boot, and plenum connection, then verifies the improvement with a second pressure test. The goal is straightforward: what you pay to heat or cool should reach the rooms you’re in.

Flex Duct Repair
Flexible duct runs in Sandy Springs attics suffer two predictable fates. Squirrels and roof rats pull at the insulation wrap. More commonly, the inner liner tears at stress points where the duct hangs over a truss or bends toward a register boot. We find crushed flex duct above original boots in maybe one of every three older Sandy Springs homes we open. Our flex duct repair replaces the damaged section with new insulated flex, supports it properly to eliminate strain, and seals both ends with mastic and mechanical fasteners. The Rotobrush and Nikro equipment in our vans lets us verify the repair with camera inspection before we close the access.

Metal Duct Repair
Galvanized metal trunk lines in Sandy Springs’s older homes corrode at the seams where condensation collects, particularly in the humid months from May through September when the system runs almost continuously. We cut out the corroded section, fabricate a replacement from matching gauge metal, and seal with mastic and fiberglass mesh. Metal work costs more than flex repair but lasts longer in high-temperature zones near the air handler. We photograph the corrosion before we cut and the finished weld before we seal.

Duct Insulation
Attic ductwork in Sandy Springs operates in an environment that hits 140°F in July. Uninsulated or poorly insulated supply lines lose capacity before the air reaches the register. We install fresh insulation wrap on repaired or replaced runs, sealed at every seam with vapor-barrier tape. In homes near the Chattahoochee where ground-level humidity runs higher, proper insulation also reduces condensation on the duct exterior that can drip onto ceiling drywall.

Mastic Sealant Application
Mastic is the standard for durable duct sealing, and it’s the backbone of most Sandy Springs jobs we do. Unlike foil tape, which degrades in attic heat, mastic remains flexible and maintains its seal through decades of thermal cycling. We brush or trowel mastic onto every joint, seam, and penetration, then embed fiberglass mesh at stress points. The result is a sealed system that holds pressure. We document the application with photos and verify with post-repair pressure testing.

Air Leak Repair
Some leaks aren’t in the duct itself but in the connection between the duct and the building. Return air plenums in Sandy Springs’s older homes often draw from wall cavities or panned floor joists that were never sealed to the conditioned envelope. We seal these pathways with sheet metal and mastic, preventing the system from pulling attic dust or garage fumes into the airflow. The camera shows the gap before we start and the sealed assembly after.

AfterTrusted Brands We Service in Sandy Springs
Our vans carry professional-grade equipment from Abatement Technologies, Guardsman, and Rotobrush, with Nikro HEPA extractors for source removal work. These aren’t proprietary tools with made-up specs, they’re trade-recognized brands any homeowner can look up. We stock flex duct, mastic, and register boots sized for the Sandy Springs housing stock, so most repairs don’t wait on parts. For the commercial-grade systems in Perimeter Center high-rises, we coordinate access and equipment through our Atlanta office, but the documentation standard stays the same: written price first, photo record after.
Common Duct Repair & Sealing Problems We See in Sandy Springs Homes

- Delaminating duct board in 1960s-1980s homes. The fiberglass duct board installed in Sandy Springs’s original build-out crumbles and sheds fibers after 40-50 years of Georgia humidity. Technicians working near Hammond Drive and Roswell Road find this failure mode regularly. It’s largely absent in the newer construction of Alpharetta or Johns Creek just up GA-400.
- Disconnected or crushed flex duct above original register boots. Older attic spaces in Sandy Springs ranch homes often have flex runs that have pulled loose from the boot or been crushed by storage or rodent activity. The homeowner feels weak airflow at the register; the problem is ten feet away in the attic.
- Mold colonization in river-adjacent neighborhoods. The Chattahoochee River creates localized elevated humidity along Sandy Springs’s western boundary. Older duct systems with cracked mastic seals or unsealed access panels draw in that moist air, providing the conditions for biofilm growth inside the trunk line.
- Leaky return air pathways pulling unconditioned air. In split-level homes common to the North Springs area, return plenums often connect to wall cavities that communicate with the garage or crawl space. The system works harder to condition air that never stays conditioned.

FAQs - Duct Repair & Sealing in Sandy Springs

Those neighborhoods were built during Sandy Springs’s unincorporated period, 1965-1990, when Fulton County oversight was lighter and duct installation quality varied widely. The original fiberglass duct board and early flex duct in those homes is now 40-50 years old, and Georgia’s sustained humidity causes delamination and fiber shedding that rarely occurs in the newer construction of Alpharetta or Johns Creek. We find decay patterns in Sandy Springs attics that we simply don’t see a few exits north on GA-400. Call (678) 904-9744 for a camera inspection and written estimate.
The river creates localized elevated ground-level humidity in adjacent neighborhoods, which raises the risk of mold colonization inside older duct systems where mastic seals have cracked or access panels were never properly sealed. Homes near the river often need more extensive sealing and sometimes source removal before a standard duct cleaning is effective. Our crews carry extra mastic stock and HEPA filtration for these jobs. Call (678) 904-9744 to discuss your home’s location and what we typically find nearby.
A typical ranch job starts with a camera inspection of every accessible run, followed by a duct blaster test to quantify leakage. We photograph the condition we find, then present a written scope and price before any repair begins. Most Sandy Springs ranches need mastic sealing at register boots and plenum joints, plus one or two flex duct repairs where runs have disconnected or crushed. The job concludes with a second pressure test and a photo record of the completed work. Call (678) 904-9744 to schedule an inspection.
Yes, but only if the sealing is comprehensive and paired with proper filtration. Sandy Springs’s spring pollen load is among the heaviest in metro Atlanta, and leaky return pathways pull that pollen directly from attic or wall cavities into the system. Sealing those pathways, combined with a properly fitted media filter, reduces the pollen load circulating through the home. Sealing alone won’t cure allergies, but it removes a major source of recontamination. Call (678) 904-9744 for an assessment of your system’s leakage points.
Yes. Perimeter Center’s mixed-use towers and high-rise condominiums use commercial-grade air-handling systems with different access requirements, pressure ratings, and equipment clearances than residential ductwork. Our technicians coordinate with building management for access and use equipment sized for commercial plenums and risers. The documentation standard stays identical: written price first, photo record after, 365-Day Done Right Promise in writing. Call (678) 904-9744 to discuss your building’s specific system.
