Our Duct Repair & Sealing Services in Druid Hills
Duct Sealing
Air leaks at plenum connections and register boots are common in Druid Hills homes where builder-grade sealants have failed after 2-3 years of humid, shaded conditions. We seal every joint with mastic sealant, not tape that peels. A typical duct sealing job in Druid Hills runs $180-$340 for partial sealing and $400-$650 for whole-system sealing. The work usually takes 2-4 hours, and you’ll feel the difference in room-to-room airflow immediately.
Flex Duct Repair
This is the service we perform most often in Druid Hills. Mid-century flex duct from 1960s-70s retrofits was frequently run unsupported through damp crawl spaces beneath shaded, clay-heavy lots. The insulation jacket compresses and rots from the outside in. We responded to a Colonial Revival on Lullwater Road where the homeowner reported musty odors and high utility bills. Our crew found the original 1970s flex duct in the crawl space had its insulation jacket compressed and rotting from decades of damp, shaded conditions. We replaced the damaged sections with new, properly supported R-8 flex duct and sealed all joints with mastic, restoring airflow and eliminating the biofilm odor. Flex duct repair in Druid Hills typically runs $250-$480 per section.
Metal Duct Repair
Some Druid Hills homes have original galvanized metal duct from 1950s HVAC retrofits. The seams corrode, especially in uninsulated attic runs where temperature swings cause condensation. We can patch corroded sections, reseal longitudinal seams, and reinforce sagging supports without replacing entire runs. Metal duct repair in Druid Hills generally costs $200-$550 depending on accessibility and extent of corrosion.
Duct Insulation
Uninsulated or poorly insulated ductwork in Druid Hills crawl spaces and attics loses conditioned air before it reaches your rooms. We install proper R-8 insulation on flex duct replacements and can retrofit insulation jackets on accessible metal runs. Given Druid Hills’ perpetually damp crawl spaces, proper insulation is not optional. It prevents condensation on cold duct surfaces that feeds mold growth. Duct insulation work in Druid Hills ranges from $300-$600 for partial retrofit to $700-$1,200 for full system wrapping.

Trusted Brands We Service in Druid Hills
We carry equipment and parts from Nikro, Honeywell, and Aprilaire - the same brands serious HVAC contractors specify for their own homes. Our Rotobrush agitation systems and HEPA vacuuming equipment handle the sticky organic residue that simple brush rigs can’t touch. For Druid Hills customers, that means we don’t wait on parts. We stock common flex duct sizes, mastic sealants, and insulation jackets so most jobs finish the same day we start.
Common Duct Repair & Sealing Problems We See in Druid Hills Homes
- Builder-grade sealants fail within 2-3 years in Druid Hills’ humid, shaded conditions, causing air leaks at register boots and plenum connections that waste energy and pull in crawl space air.
- Mid-century flex duct sags and collects moisture when installed unsupported in damp crawl spaces, leading to collapsed sections that block airflow entirely and create back-pressure on your HVAC system.
- Pollen-laden organic residue from white oaks and hickories cakes inner duct liners with a sticky film that requires Rotobrush agitation and HEPA vacuuming - simple brushing won’t clear it.
- Original metal duct from 1950s retrofits corrodes at seams in uninsulated attic runs, especially where temperature swings cause condensation on cold supply lines during Atlanta’s humid summers.

FAQs - Duct Repair & Sealing in Druid Hills
Druid Hills’ Olmsted-designed tree canopy and dense clay soils keep crawl spaces perpetually damp, which rots flex duct insulation from the outside in and degrades sealants faster than in sunnier, better-drained suburbs. We use mastic sealant instead of tape and properly support all flex duct to prevent moisture collection. Call (855) 305-5564 for a free inspection - we’ll show you exactly what’s failing and why.
Yes. We access flex duct through the crawl space or attic in nearly all Druid Hills homes, leaving your plaster walls and historic millwork untouched. We replace damaged sections with new, properly supported R-8 flex duct and seal all joints with mastic. Most sagging flex duct replacements are completed in 3-5 hours. Call (855) 305-5564 for a free estimate.
R-8 flex duct with a vapor-resistant outer jacket performs best in Druid Hills’ shaded, moisture-prone crawl spaces. We also ensure proper support to prevent compression, which reduces insulation value and creates cold spots where condensation forms. For metal duct, we install wrapped insulation with sealed seams. Call (855) 305-5564 to discuss your specific crawl space conditions.
Yes, but only if we seal the leaks that pull air from your crawl space and attic, not just the vents themselves. Druid Hills’ white oaks and hickories produce some of the region’s heaviest pollen loads, and that pollen enters your duct system through gaps at plenum connections, register boots, and access panels. Proper mastic sealing eliminates those entry points. We also recommend pairing sealing with thorough duct cleaning for existing buildup. Call (855) 305-5564 for a combined estimate.
Yes. We regularly patch corroded sections, reseal longitudinal seams, and reinforce supports on original metal duct in Druid Hills homes. Replacement of entire runs is only necessary when corrosion is extensive or the duct has collapsed. We inspect with a camera first to determine the most cost-effective approach. Metal duct repair in Druid Hills typically runs $200-$550. Call (855) 305-5564 for an exact quote - estimates are free.
