Duct repair and sealing in Skidaway Island typically runs $280–$780 depending on whether we’re patching flex duct runs, resealing metal seams with mastic, or replacing collapsed sections in attic spaces. Most Skidaway Island homeowners call us after noticing uneven cooling, musty odors, or rising energy bills — and we’re usually on-site within 24 hours. Call (877) 565-7296 for a free estimate.
We’ve worked inside enough homes on Skidaway Island to know the pattern before we even pull into the driveway. The marsh-surrounded microclimate here — ZIP code 31411, completely ringed by tidal salt marshes — creates a humidity envelope that mainland Savannah doesn’t replicate. That saturated air works its way into unconditioned attics and crawl spaces, and your ductwork pays the price. Our Duct Repair & Sealing team has spent two decades tracing these specific failure modes in coastal Georgia homes.
Why Everest Air Duct Cleaning Service Georgia Is Skidaway Island’s Preferred Duct Repair & Sealing Company
Scott Gray has worked every job for 20 years — your home gets the owner, not a substitute. That matters on Skidaway Island, where diagnosing duct failure requires understanding whether you’re dealing with simple dust buildup, moisture-driven mold colonization, or the collapsed flex liner that we see repeatedly in The Landings. An entry-level tech might run a brush through a duct and miss that the mylar liner has detached entirely.
433 neighbors have rated us 4.9 stars — the numbers speak for themselves. We’ve earned that volume by showing up with the right diagnosis and fixing what we find, not outsourcing to a second contractor.
Our response time to Skidaway Island is typically same-day or next-day, because we dispatch from our Atlanta base with dedicated routing for Chatham County calls. We know the gated entry procedures for The Landings, the backroad approaches along Green Island Road, and the seasonal traffic patterns that affect access during peak tourism months.
We use Rotobrush contact-cleaning and Nikro HEPA extraction — the same equipment trusted in commercial remediation — but we also carry mastic sealant, insulated metal duct sections, and corrosion-resistant hardware for the repair work that cleaning alone won’t solve.
Our Duct Repair & Sealing Services in Skidaway Island
Flex Duct Repair
Flex duct repair is our most frequent call on Skidaway Island, and it’s not coincidence. The original flexible ductwork installed in The Landings homes during the 1980s and 1990s has absorbed decades of ambient humidity through vented attic spaces. The inner mylar liner — the smooth surface that actually carries air — separates from the insulation jacket and collapses into the airflow path. We’ve pulled out sections where the liner looked like a deflated balloon, completely blocking supply to a bedroom or office. We replace these failed runs with properly supported insulated duct, sized correctly for the original HVAC design, and we add support straps where the old sagging contributed to the failure.
Mastic Sealant Application
Metal duct seams that were tight twenty years ago have loosened under thermal expansion and salt-air corrosion. We seal every accessible joint with UL-181 rated mastic — not duct tape, which degrades in humid attics within months. On Skidaway Island, we apply mastic heavier at plenum connections and air handler cabinets where salt corrosion has pitted the metal surface. The mastic creates a flexible, permanent seal that moves with the ductwork through heating and cooling cycles without cracking.
Duct Insulation Replacement
Insulation wrapped around ductwork in Skidaway Island’s humidity envelope becomes a sponge. Once the vapor barrier tears — and it always tears where straps compress it — fiberglass insulation pulls moisture directly onto the duct surface. We strip saturated insulation, repair any underlying corrosion, then re-wrap with fresh insulation and a proper vapor barrier sealed at all seams. In crawl spaces where groundwater proximity keeps humidity above 70% year-round, we sometimes recommend upgrading to closed-cell foam insulation on exposed metal trunk lines.
Metal Duct Repair
Galvanized steel ductwork and plenums in coastal homes develop pinhole corrosion at seams and corners where salt-laden air concentrates. We patch small corrosion areas with galvanized sheet metal and mastic, or replace entire plenum sections when the metal has thinned beyond reliable repair. For air handler cabinets showing salt corrosion at the base — common in homes where the unit sits in a vented crawl space — we fabricate stainless steel transition pieces that outlast the original equipment.

Trusted Brands We Service in Skidaway Island
We install Honeywell and Aprilaire air quality products in-house, which matters when duct repair reveals that your system needs more than mechanical fixes. A Honeywell whole-home dehumidifier, for instance, can pull enough moisture from the return air to prevent the condensation cycle that keeps destroying ductwork in Skidaway Island’s climate. We stock Aprilaire media filters with higher MERV ratings that catch the mold spores and fiberglass particles released by deteriorating flex duct — so when we seal your system, we’re also upgrading your filtration in the same visit. No waiting on parts, no second appointment, no handing you off to another contractor.
Common Duct Repair & Sealing Problems We See in Skidaway Island Homes
- Collapsed flex duct liner in The Landings. The mylar inner liner separates from the wire helix and insulation after 25–45 years of humidity exposure, blocking airflow to specific rooms. Homeowners often call for cleaning when the real problem is a collapsed duct that needs section replacement.
- Salt-air corrosion of metal plenums and air handler cabinets. The same salt that pitts outdoor hardware attacks indoor metal in vented crawl spaces and attics, creating air leaks at seams and reducing system efficiency by 15–30% before homeowners notice warm spots.
- Mold colonization following chronic condensation. Persistent humidity in unconditioned spaces keeps duct surfaces wet enough for mold growth even in winter, requiring biocidal treatment and resealing after cleaning — otherwise the problem returns within one cooling season.
- Disconnected duct runs from thermal expansion cycles. Decades of heating and cooling cause duct sections to pull apart at connections, especially where original installers used minimal mechanical fasteners. We find these leaks with blower-door testing and seal them permanently.

FAQs — Duct Repair & Sealing in Skidaway Island
The barrier island’s complete encirclement by tidal salt marshes creates near-constant saturated humidity that mainland Savannah — even coastal Chatham County a few miles inland — does not replicate. This moisture absorbs into flex duct’s mylar liner over decades, causing the adhesive to fail and the liner to delaminate and collapse. We’ve replaced flex duct in The Landings that failed in 25 years, while similar vintage ductwork in downtown Savannah often lasts 35–40 years.
Uneven cooling between rooms, musty odors that return within weeks of cleaning, visible debris or insulation particles blowing from registers, or rooms that never reach thermostat setpoint despite adequate airflow at the vent all suggest duct damage rather than simple contamination. Call (877) 565-7296 — we’ll inspect with a camera and tell you definitively whether cleaning or repair is the right first step.
Yes — we fabricate plenum patches and transition pieces from stainless steel specifically for Skidaway Island’s salt-air environment, and we use corrosion-resistant hardware for all access doors and supports. Standard galvanized steel lasts roughly half as long here as it does inland, so we specify materials for coastal durability.
We address condensation by sealing duct leaks that draw humid attic or crawl space air into the system, adding or replacing insulation to prevent surface temperature drop below dew point, and installing Honeywell or Aprilaire dehumidification equipment when the home’s overall moisture load requires it. Biocidal treatment kills existing mold, but sealing and moisture control prevent regrowth — cleaning alone never does.
Homes with original flex duct from the 1980s–1990s should be inspected every 3–5 years; homes with replaced ductwork every 5–7 years. We recommend more frequent checks if you’ve noticed efficiency drops or if your system operates in a vented crawl space or attic. Call (877) 565-7296 to schedule — estimates are free and include full camera inspection.
