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 runs $450-$1,800 per system depending on whether we’re sealing accessible joints or replacing moisture-damaged insulation, and most jobs are scheduled within 3-5 business days with a written price delivered before any panel comes off. We dispatch crews from our Atlanta office to Sandy Springs daily, and we’re familiar with the specific failure modes this city’s older housing stock presents: original duct board gone brittle after 40-50 years of Georgia humidity, crawlspace insulation wicking clay-soil moisture, and multi-zone systems in teardown-rebuilds where partial sealing leaves two-thirds of the home leaking into unconditioned space.

Our Duct Repair & Sealing Services in Sandy Springs

Duct Sealing
Most Sandy Springs homes lose 20-30% of conditioned air through leaks at takeoffs, seams, and plenum connections. We seal with mastic compound and mechanical fasteners, not tape that degrades in Georgia’s humidity. In teardown-rebuilds along Mount Vernon Road with three-system layouts, we seal zone by zone and test each independently. A single-system seal in Sandy Springs runs $450-$850; multi-system homes typically see per-system pricing at the lower end of that range due to shared access.

Flex Duct Repair
Flex duct in Sandy Springs’s original 1970s-1990s homes has often collapsed at bends or pulled loose at takeoffs. We replace damaged runs with new insulated flex, supported every 4 feet per code, and photograph every connection before closing. A typical flex duct replacement in Sandy Springs runs $280-$520 per run depending on length and access.

Metal Duct Repair
Where original duct board has failed entirely, we fabricate galvanized sheet metal transitions and trunk sections in our Rotobrush-equipped service vehicles. Metal repair in Sandy Springs typically runs $380-$740 for localized replacement, or $1,200-$1,800 for full trunk rebuilds in large homes with extensive linear footage.

Duct Insulation
This is where Sandy Springs differs from neighboring cities. In the wooded neighborhoods between the Chattahoochee River and Roswell Road, crawlspace-mounted duct systems are the norm rather than the slab-on-grade runs common in neighboring Dunwoody. Duct insulation here routinely wicks Georgia clay-soil moisture to the point of mold saturation, a failure mode that calls for full wrap replacement rather than resealing. We remove saturated insulation, treat the metal or duct board beneath, and install new R-8 fiberglass wrap or closed-cell foam depending on the application. Insulation replacement in Sandy Springs runs $600-$1,400 per system.

Mastic Sealant Application
Mastic is a water-based sealant we brush onto joints and seams; it remains flexible and bonds to metal, duct board, and flex duct connections. In Sandy Springs’s high-humidity environment, mastic outperforms foil tape by years. We apply it to every accessible joint during a seal job, and the work is photographed for the documented photo record included on every visit.

AfterTrusted Brands We Service in Sandy Springs
Our equipment roster includes Rotobrush for mechanical agitation, Nikro for negative-pressure extraction, and Honeywell and Aprilaire components for zone control and filtration upgrades. We stock common fittings and insulation materials for Sandy Springs’s predominant system types, so most jobs don’t wait on parts. When a teardown-rebuild along Heards Ferry Road needs a specific Honeywell zone damper or an Aprilaire media cabinet, we source it without extended delays. Customers can verify every brand we name independently; we don’t make performance claims beyond manufacturer specifications.
Common Duct Repair & Sealing Problems We See in Sandy Springs Homes

- Original duct board gone brittle and friable. The bulk of Sandy Springs’ residential stock is custom and semi-custom homes built between the late 1960s and mid-1990s. Their fiberglass duct board has spent decades in Georgia humidity and is now crumbling at seams that were never mechanically fastened correctly to begin with. We find this in ranches off Roswell Road and split-levels near the river.
- Crawlspace insulation saturated with clay-soil moisture. In the wooded corridors near the Chattahoochee, crawlspace-routed ducts absorb soil moisture until the insulation is mold-saturated. Sealing over wet wrap traps the problem. We replace the wrap, treat the underlying duct, and seal only after the system is dry.
- Multi-zone systems partially sealed by previous contractors. Newer luxury teardown-rebuilds along Mount Vernon Road and Heards Ferry Road carry three-system, multi-zone layouts. Homeowners often seal only the system they can see, leaving two more zones leaking into unconditioned attic or crawlspace. We inspect and quote every zone, not just the convenient one.
- Accelerated pollen buildup at air intakes. Atlanta ranks among the highest-pollen metros in the United States, and Sandy Springs’s dense tree canopy means oak and pine seasons hit hard. Heavy particulate loads strain filters and drive debris into ductwork, compounding leak problems by clogging the very paths air is supposed to travel.
Pricing for Duct Repair & Sealing in Sandy Springs, GA
We publish ranges because Haven Standard Clause 1 requires a written price before any work starts. Here’s what duct repair and sealing costs in Sandy Springs:
| Service | Typical Range in Sandy Springs |
|---|---|
| Single-system duct sealing (mastic, accessible joints) | $450 - $850 |
| Multi-system sealing (2-3 zones, per system) | $380 - $720 per system |
| Flex duct replacement (per run) | $280 - $520 |
| Metal duct repair / transition rebuild | $380 - $740 localized; $1,200 - $1,800 full trunk |
| Duct insulation replacement (per system) | $600 - $1,400 |
| Camera inspection with written report | $180 - $280 (credited toward repair if scheduled) |
What moves a job toward the higher end: crawlspace access requiring full protective entry, mold-saturated insulation requiring removal and treatment, three-system homes with extensive linear footage, or duct board so degraded it needs replacement rather than sealing. What keeps it lower: single-system homes with basement or attic access, recent flex duct in good condition, and straightforward joint sealing without insulation work.

FAQs - Duct Repair & Sealing in Sandy Springs

Yes, if all three are leaking. In Sandy Springs’s teardown-rebuilds along Mount Vernon Road and Heards Ferry Road, we routinely find that previous contractors sealed only the primary system and left two zones leaking into unconditioned space. We inspect and quote every zone independently; multi-system homes typically see per-system pricing at a reduced rate due to shared mobilization. Call (470) 495-9370 for a written estimate covering all systems.
Because clay-soil moisture wicks upward into crawlspace-mounted insulation, and Sandy Springs’s wooded neighborhoods between the Chattahoochee and Roswell Road have more of this configuration than slab-on-grade areas like Dunwoody. Georgia’s long humid summers compound the problem. Wet insulation cannot be sealed over; it must be removed, the underlying duct treated, and new wrap installed. We document the condition with photos before touching anything.
It depends on condition. If the duct board is intact but leaking at seams, we can seal with mastic and mechanical fasteners. If it’s brittle, friable, or showing microbial growth - common after 40-50 years in Georgia humidity - replacement with sheet metal or new duct board is the only durable fix. We make this determination with a camera inspection and show you the photos before quoting either approach.
Every CleanRun job concludes with a Documented Photo Record: photos of every joint sealed, every transition rebuilt, and every insulation wrap replaced, delivered to you as a standard deliverable. Haven Standard Clause 2 requires this documentation on every visit. You don’t take our word for it; you see what was done, start to finish.
More involved, yes; more complicated for you, no. Multi-zone systems require zone-by-zone inspection, independent pressure testing, and often coordination with existing Honeywell or Aprilaire zone controls. We map the system, quote each zone with its own written price, and seal only what you approve. The documentation includes photos organized by zone so you can verify work on the third-floor system as clearly as the basement unit.
