We’re familiar with the split character of Norcross housing: the small historic downtown core where late-19th-century homes have had HVAC retrofitted into spaces never designed for it, and the far larger ring of 1970s-1990s subdivisions and apartment complexes where original flex duct has spent three to five decades in unconditioned Georgia attics. Our crews serve Norcross from our Atlanta office, and we know the specific failure modes this combination of age, humidity, and construction era produces.

Our Duct Repair & Sealing Services in Norcross
Duct Sealing with Mastic Sealant
Norcross’s original 1980s flex duct systems were sealed with tape that degrades in attic heat. We remove failed tape and apply mastic sealant, a fiber-reinforced compound that remains flexible and airtight across temperature swings. In the garden-style apartments off Jimmy Carter Blvd, we regularly find boot connections where tape has dried and cracked completely through, leaking conditioned air into the attic for years. Mastic sealing restores the pressure boundary the system was designed to maintain.
Flex Duct Repair
Flex duct in Norcross’s unconditioned attics sags, crushes, and detaches. We replace damaged runs with properly supported flex, reattach at boots with mechanical fasteners plus mastic, and ensure adequate slope for drainage. This is the most common repair we perform in Norcross’s 1970s-1990s housing stock. The field vignette from a 1984 building off Jimmy Carter Blvd is typical: our tech ran a camera inspection and found the main trunk flex duct completely detached at the boot over the bathroom, dumping cold air into the attic for years. We reattached the flex, sealed the boot with mastic, and wrapped the run in new insulation. The tenant called back a week later to say the unit was finally comfortable.
Metal Duct Repair
The historic downtown core and some early subdivisions contain galvanized metal ductwork, often retrofitted with transitions to flex that fail at the joint. We repair metal runs, replace corroded sections, and properly seal transitions. Metal duct in Norcross’s older homes frequently lacks insulation wrap, causing condensation on the exterior that drips into ceilings and walls.
Duct Insulation
Georgia’s humid summers make uninsulated or degraded duct insulation a major efficiency loss. We replace water-damaged or vermin-compromised insulation with new wrap rated for attic installation. In Norcross’s high-density rental corridors, where multiple generations cook daily and humidity runs high year-round, proper insulation also prevents condensation that feeds mold growth inside supply ducts.

Common Duct Repair & Sealing Problems We See in Norcross Homes
- Detached flex at boot connections. In the 1980s garden-style apartments off Jimmy Carter Blvd, our camera inspection routinely shows flex duct fully detached at the boot connections in attic spaces, meaning some units have been conditioning the attic, not the living room, for years. Landlords only find out when a duct cleaning crew goes up top.
- Grease-laden returns in high-density households. Heavy daily cooking in multigenerational immigrant households along Buford Highway coats return ducts with grease, which traps pollen and feeds mold in Georgia’s humid summers. Standard cleaning without degreasing leaves the problem intact.
- Condensation from oversized or undersized equipment. Original equipment in Norcross’s 1970s-1990s buildings often runs outside design parameters, causing condensation inside supply ducts. Resealing alone won’t fix this; the underlying humidity load must be addressed through proper equipment sizing or dehumidification.
- Sagging flex in unconditioned attics. Decades of attic heat have degraded the wire helix in original flex duct, causing runs to sag and crush at bends. Airflow drops. Rooms at the end of the run never condition properly.
Pricing for Duct Repair & Sealing in Norcross, GA
Most residential duct sealing jobs in Norcross run $280-$450 for partial system work and $450-$950 for full system resealing with mastic. Flex duct repair, including replacement of damaged runs and reattachment at boots, typically falls between $180-$340 per run. Metal duct repair starts around $220 for minor section replacement and can reach $600+ for extensive corrosion remediation in older homes. Duct insulation replacement runs $2.50-$4.50 per linear foot depending on diameter and attic accessibility.
What moves the price: attic accessibility (crawl vs. walkable), the number of disconnected or damaged runs, whether grease remediation is required, and whether the plenum itself needs resealing. We deliver a written price before any work starts, every time, under Haven Standard Clause 1. No per-vent pricing. No teaser coupons.

FAQs - Duct Repair & Sealing in Norcross
The 1980s garden-style apartment complexes in this corridor were built with early-generation flex duct in unconditioned attics, secured with tape that degrades in Georgia’s heat and humidity over 30-40 years. The wire helix supporting the flex corrodes, the duct sags, and eventually detaches entirely at boot connections. Because these units often condition adequately in mild weather, tenants and landlords may not notice the problem until peak summer demand exposes the failure. Call (470) 516-9337 for a camera inspection that will show exactly what’s happening in your attic.
Duct sealing can fix the problem if the issue is leaks at joints, boots, or disconnected runs, which we find in roughly 60% of 1980s Norcross properties we inspect. If the flex duct itself has detached or crushed, sealing alone won’t restore airflow, and flex duct repair or replacement is needed. We determine which with a camera inspection before quoting any work. Call (470) 516-9337 to schedule.
Yes. Our cleaning protocol follows NADCA ACR standards with negative-pressure extraction, meaning the vacuum maintains suction at the collection point while agitation tools dislodge debris. In Norcross’s older homes, we adjust agitation intensity for fragile original flex duct and photograph every run before and after as part of the Documented Photo Record included on every visit. The photo record is delivered to you as a standard deliverable, not an extra.
Metro Atlanta’s spring pollen season, routinely among the highest pollen counts in the U.S., drives allergen deep into duct systems through leaks and disconnected returns. Sealed ductwork prevents pollen infiltration; unsealed systems recirculate it continuously. We see a sharp seasonal spike in Norcross demand for both duct cleaning and sealing work in April and May, after oak, pine, and sweet gum saturation peaks. If your system has leaks, sealing before pollen season is more effective than cleaning after it.
For 1970s-1990s properties in Norcross’s high-humidity climate with original flex duct, we recommend inspection every 3-5 years, or immediately if tenants report uneven cooling, musty odors, or unexplained energy spikes. The combination of aging materials, heavy cooking loads, and Georgia humidity produces accelerated degradation compared to newer construction or drier climates. We offer property managers written scope and pricing for multi-unit buildings, with photo documentation for each unit. Call (470) 516-9337 to discuss a building assessment.
