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-$780 for most residential jobs, with flex duct replacement running higher in multi-story custom homes where access is tight.

We’ve worked Sandy Springs homes since 2013 - from the wooded lots of Heards Ferry to the condo stacks near Riverside Drive - and the pattern is consistent: original flex duct from the 1980s and 90s is failing right on schedule. The fiberglass liner sheds. The plenum joints separate. The mastic sealant someone applied in 2003 has turned to dust. Our Duct Repair & Sealing team documents every run with before-and-after photos, so you see what was actually fixed.

Our Duct Repair & Sealing Services in Sandy Springs

Duct Sealing
Leaky ductwork in Sandy Springs homes typically wastes 20-30% of conditioned air before it reaches the registers. In the multi-story custom homes common in Spalding Woods and Heards Ferry, that loss is concentrated at plenum joints and where flex duct connects to metal trunk lines. We seal with mastic sealant rated for Georgia’s humidity cycles, not foil tape that peels in attic heat. Every sealed joint is photographed. A typical duct sealing job in Sandy Springs runs $280-$450 for a single system.

Flex Duct Repair
Original fiberglass-lined flex duct in Sandy Springs homes is now 30-50 years old. The liner degrades, sheds particulate, and creates the grey dust our crews find blowing from second-floor registers. In Spalding Woods, our crew pulled a camera inspection through a 1988 custom home’s original fiberglass-lined flex duct and found the liner shedding like felt above the air handler. We ran negative pressure HEPA filtration while agitation tools loosened the debris, then applied mastic sealant and Guardsman flex at the plenum joints. The homeowner’s second-floor registers finally stopped blowing that grey dust. Flex duct repair in Sandy Springs typically ranges $340-$620 per run, depending on attic access.

Metal Duct Repair
Galvanized metal trunk lines in older Sandy Springs homes corrode at seams and where condensation pools in low spots. The Chattahoochee River valley’s elevated humidity accelerates this corrosion compared to drier eastern neighborhoods. We cut out damaged sections, fabricate replacements on-site, and seal with mastic. Metal duct repair in Sandy Springs generally runs $380-$780.

Duct Insulation
Uninsulated or degraded duct insulation in Sandy Springs attics loses thermal efficiency fast - particularly critical given Georgia’s cooling-dominated climate. We install foil-faced fiberglass insulation rated for attic temperatures, sealed at all seams. Duct insulation work in Sandy Springs typically costs $420-$680 per system.

Mastic Sealant Application
Mastic is the standard for permanent duct sealing in Sandy Springs’s humidity. We apply it with a brush or spray at all joints, boots, and plenum connections, then photograph the finished work. Mastic sealant application as a standalone service runs $280-$450.

Air Leak Repair
We pressure-test duct systems to locate leaks, then repair with appropriate materials - mastic for metal, sealed mechanical connections for flex. Air leak repair in Sandy Springs is typically $320-$580.

Common Duct Repair & Sealing Problems We See in Sandy Springs Homes

- Shared building systems in condos and apartments. One unit’s duct repairs often require coordinating shutoffs and access with neighbors. A failed seal in a shared chase can push conditioned air - and debris - into adjacent units. We scope these jobs with written coordination protocols.
- Restricted parking and equipment access on dense streets. Crews run longer hose runs from the truck, and every extra joint in a temporary run is a potential leak point that can mask a duct repair problem. We pressure-test temporary runs before starting permanent work.
- Original 1970s-90s fiberglass-lined flex duct near the Chattahoochee corridor. Humidity-driven microbial growth degrades the liner, so sealing a leak without replacing the shedding liner traps moisture and particulate inside the system. We camera-inspect before recommending any seal-only approach.
- Renovation-damaged ductwork in premium homes. Kitchen and bath contractors in Sandy Springs routinely cut or compress duct runs without informing homeowners. We find these with camera inspection and document the damage photographically.

FAQs - Duct Repair & Sealing in Sandy Springs

Yes, but shared stacks require written coordination with your HOA and adjacent units before we open any chase. We document the shared system with photos, seal only your unit’s accessible connections, and flag any cross-unit leakage for building management. Call (678) 679-7540 to schedule an inspection with written scope.
Yes. Mastic sealant remains flexible through Georgia’s humidity and attic temperature swings; foil duct tape degrades and peels within 2-3 years in Sandy Springs attics. For your 1985 flex duct, we camera-inspect the liner condition first - if it’s shedding, sealing alone traps debris. The written estimate will specify whether sealant-only or liner replacement is the right scope. Call (678) 679-7540 for a free inspection.
We start with a camera inspection of accessible runs, pressure-test the system to quantify leakage, then deliver a written price with photo documentation of what we found. Work typically includes accessing attic trunk lines, replacing degraded flex at plenum connections, and sealing all joints with mastic. Every run is photographed before and after. Most Sandy Springs multi-story jobs take 4-6 hours. Call (678) 679-7540 to schedule.
We survey access when you call and plan hose runs accordingly. On restricted streets near Riverside or dense condo clusters, we may stage equipment in a designated loading zone and run longer hoses - each temporary connection is pressure-tested before we start permanent work. The written scope notes any access constraints and how we addressed them.
The Chattahoochee River valley creates a measurably higher humidity microclimate along Sandy Springs’s western edge. Combined with original 1970s-90s fiberglass duct liner that traps moisture, this produces visible microbial growth in return-air plenums that comparable homes in drier eastern Sandy Springs or Dunwoody rarely show. Sealing without replacing the degraded liner makes it worse - we address both. Call (678) 679-7540 for a camera inspection and written remediation scope.
