Scott Gray has spent 20 years crawling through Atlanta’s dirt crawl spaces and tight intown attics — from the 1950s brick ranches of Browns Mill to the retrofitted bungalows of Cabbagetown. We know the difference between a galvanized sheet-metal trunk that’s rusted through from Piedmont humidity and a flex duct that’s crushed in a steep-roof attic. That crawlspace-level experience matters when your system is pulling in red clay dust and pollen instead of conditioned air.
Why Everest Air Duct Cleaning Service Georgia Is Atlanta’s Preferred Duct Repair & Sealing Company
433 neighbors across Atlanta have rated us 4.9 stars — the numbers speak for themselves. Those reviews come from homeowners in Adams Park, Cascade Heights, and Brookhaven who’ve watched Scott Gray diagnose their ductwork in person, not dispatched a franchise crew they’d never met.
We’re owner-operated: Scott Gray has worked every job for 20 years — your home gets the owner, not a substitute. That matters in Atlanta, where a 1960s ranch in Browns Mill and a 1920s bungalow in Cabbagetown need entirely different repair approaches. We use Rotobrush contact-cleaning and Nikro HEPA extraction — the same equipment trusted in commercial remediation — plus mastic sealants rated for Georgia’s humidity cycles.
Our response time to intown Atlanta neighborhoods averages under two hours. We carry metal duct stock, flex duct in common diameters, and professional-grade mastic on every truck, so most repairs finish in a single visit without waiting on parts.
Our Duct Repair & Sealing Services in Atlanta
Duct Sealing with Mastic Sealant
Atlanta’s 50+ inches of annual rainfall and 80% summer humidity punish duct joints. We apply fiberglass-reinforced mastic sealant to every metal-to-metal connection, creating a flexible, vapor-resistant bond that outlasts tape in crawl-space conditions. In homes near Cochran Park and Hillpine Park with original galvanized trunks, proper mastic sealing often cuts energy bills 15–20% by restoring designed airflow.
Flex Duct Repair
Retrofit flex duct in Atlanta’s steep-roof attics — common in Virginia-Highland and Inman Park bungalows — gets crushed by storage, damaged by roof leaks, or disconnected at plenum connections. We replace damaged runs with properly sized, insulated flex duct and secure it with mechanical straps, not tape that fails in attic heat. Two decades of crawlspace-level experience goes into every inspection.
Metal Duct Repair
Original galvanized sheet-metal ducts in Atlanta’s 1950s–1970s ranch homes rust through at floor penetrations where crawl-space moisture concentrates. We fabricate custom metal transitions, patch rusted sections with matching gauge steel, and seal with mastic. From dirty ducts to repaired, sealed, and sanitized — we handle the full scope.
Duct Insulation Replacement
When fiberglass liner delaminates inside metal duct — the failure mode we see constantly in South Atlanta’s humid crawl spaces — we remove the collapsed material and re-line with fresh, mold-resistant insulation. This isn’t a cleaning issue; it’s structural repair that restores both airflow and indoor air quality.

Trusted Brands We Service in Atlanta
We install Honeywell and Aprilaire air quality products in-house, letting us close the loop from dirty ducts to genuinely cleaner air. For duct repair specifically, we stock Atlanta-common duct diameters and fittings, plus professional-grade mastic sealants and metal stock. That inventory means we don’t leave your Browns Mill or Brookwood Hills home waiting on a parts run — most sealing and repair jobs finish the same day we arrive.
Common Duct Repair & Sealing Problems We See in Atlanta Homes
- Collapsed fiberglass liner in crawl-space ducts. In Atlanta’s 1950s–1970s brick ranches, decades of humidity cycling cause interior fiberglass duct liner to separate and collapse into the airstream — a failure mode almost nonexistent in slab-on-grade western cities like Phoenix. We remove the debris and re-line the metal trunk.
- Rust-through at galvanized joints. Original metal duct in unsealed dirt crawl spaces rusts where it meets the floor, pulling in humid outdoor air and Georgia red clay dust. We patch with matching steel and seal with mastic rated for wet conditions.
- Crushed retrofit duct in bungalow wall cavities. Central HVAC added to 1920s Cabbagetown and Castleberry Hill homes often runs flex duct through wall cavities never designed for airflow. These runs get crushed, kinked, or disconnected. We fabricate custom metal transitions to restore proper airflow paths.
- Disconnected plenum connections in steep attics. Atlanta’s intown neighborhoods feature steep roof pitches with tight attic clearances. Flex duct connections at plenums work loose from thermal expansion and foot traffic during maintenance. We re-secure with mechanical straps and mastic.
Pricing for Duct Repair & Sealing in Atlanta, GA

Atlanta’s older housing stock and crawl-space prevalence push most jobs toward the middle of these ranges — rust repair and liner replacement take more time than simple sealing. We inspect first, quote upfront, and never start work without your approval. Call (877) 565-7296 for an exact quote — estimates are free.

FAQs — Duct Repair & Sealing in Atlanta
Atlanta’s 1950s–1970s ranch homes were built with galvanized sheet-metal ducts routed through unconditioned dirt crawl spaces, where 50+ inches of annual rainfall and high humidity cause rust, liner delamination, and mold — failure modes that slab-on-grade or conditioned-space construction avoids. Call (877) 565-7296 for an inspection if your home fits this profile.
Yes — Atlanta’s extraordinarily dense urban tree canopy (pine, oak, and sweetgum) produces pollen loads that visibly coat surfaces yellow each spring, and that pollen enters duct systems through leaks and return-air pathways, accelerating filter loading and biological debris accumulation inside ductwork. Proper sealing reduces indoor pollen counts by closing those entry points.
We work with compact professional equipment — Nikro HEPA vacuums and portable lighting systems — and pre-cut replacement flex duct to length before entering the attic, minimizing time in confined spaces; for severely crushed runs, we sometimes route new paths through floor chases rather than fighting the original tight attic route.
Yes — sealing return-air plenums and duct joints prevents the system from pulling in unfiltered outdoor air, which in Atlanta carries pollen, mold spores, and red clay dust; we regularly measure 40–60% reduction in airborne particle counts after comprehensive mastic sealing in pollen season.
Atlanta’s humid subtropical climate and crawl-space construction cause rust-through and liner collapse that cleaning alone cannot fix — the duct structure itself has failed, and continuing to clean damaged metal or collapsed fiberglass just recirculates debris; repair restores integrity before sanitizing makes sense.
