We show up when we said we would, write the price down before touching anything, and stand behind the work with a 365-Day Done Right Promise.

Hollis Air Duct Alpharetta has been doing this since 2004. We’re part of the Garrison Partners family, independently owned and operated under The Garrison Standard. Our crews know Norcross’s housing stock the way a local mechanic knows the roads. That matters when the fix requires understanding what a 1950s return run looks like versus a 2003 flex-duct retrofit. Dispatch and scheduling are coordinated from our Atlanta office; the technicians who arrive at your door serve Norcross locally.
Why Hollis Air Duct Alpharetta Is Norcross’s Preferred Duct Sealing Company
Norcross homeowners call us because the work holds up. Every sealing job gets a written price before work begins. The price does not move at the door. If a sealed joint fails within a year, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it includes a free second visit. Not negotiated, not pro-rated. In writing.
Our technicians are background-checked and uniformed. You’ll know who is walking into your home before they arrive. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No waiting until Monday to get a callback.
We work on homes in the Norcross Historic District, along Beaver Ruin Road, off Jimmy Carter Boulevard, and through the subdivisions around Thrasher Park. That local repetition means we know what to expect before the first camera goes in the duct. A brick ranch from 1962 off Singleton Road fails differently than a vinyl-sided two-story from 1998 near Graves Park. Knowing that on arrival saves time and money.

Duct Repair in Norcross
Duct Repair in Norcross means putting the air system back together when it has physically failed: separated trunk joints, crushed metal runs, disconnected flex takeoffs, or return plenums pulling dirt from a crawlspace. This is not a cleaning. It is a structural fix. We find what is broken, show you the camera footage, and repair it by the book.
Most Norcross duct repair jobs fall between $350 and $1,500, depending on how many sections have failed and how accessible they are. We write that number down before any work starts.
What a Typical Repair Involves
We locate every leak and separation with a camera inspection, then map the failures before opening anything up. Most repairs involve pulling separated sections back together, sealing the joints with mastic and fiberglass mesh, and replacing any flex duct that has rotted or collapsed. The goal is simple: stop dumping conditioned air where it does no good.
When Duct Repair Is the Real Fix
A repair makes sense when the ducts themselves are still sound but the connections have failed. That’s common in Norcross’s 1950s and 60s homes, where original metal ductwork often outlasts the tape and hangers holding it up. If the metal is crushed or rusted through, sealing will not save it. We’ll tell you honestly which situation you have.
Air Duct Sealing in Norcross
Air Duct Sealing in Norcross means closing every gap, joint, and pinhole leak in the duct system so the air you pay to condition actually reaches the rooms. Done correctly, it uses mastic and fiberglass mesh or an aerosol sealant, applied after the leaks are mapped with a camera inspection. We do not wrap failing ducts in tape and call it sealed. That’s not sealing; that’s a temporary patch.
Whole-home air duct sealing in Norcross typically runs $850 to $2,400. The real variables are how much ductwork sits in a hot, humid attic, how many takeoffs have separated, and whether returns pull from a dirt crawlspace. The price is written down before we begin.
Sealing Methods We Use on Norcross Homes
For accessible ductwork, we apply mastic with fiberglass mesh at every joint and takeoff. It hardens into a permanent, flexible seal that does not dry out and peel like tape. For areas we cannot reach by hand, an aerosol sealant can close pinhole leaks throughout the system from the inside.
What This Fixes for Everyday Comfort
Sealed ducts mean far rooms stop being ten degrees warmer than the rest of the house. Humidity stops riding in through return leaks. The blower motor stops pulling Georgia pollen directly from the crawlspace. And the AC lasts longer because it is not fighting to pressurize a system that leaks half its air before it ever sees a register.
Trusted Brands We Service in Norcross
We service and seal duct systems built around equipment from carriers and brands most Norcross homes rely on, and our crews run professional-grade gear from Nikro, Honeywell, and Aprilaire on every job. The cameras, negative-air machines, and filtration tools we bring are the same ones commercial crews use, not hardware-store specials. For Norcross customers, that means we can identify what your system needs quickly and get the parts or materials same week. Every brand we install or seal around gets the same written price, the same 365-Day Done Right Promise, and the same clean-site standard.
Common Duct Sealing Problems We See in Norcross Homes
- Leaky return ducts in older crawlspaces. Norcross’s humid climate makes crawlspace returns especially bad. When the return side has gaps, it pulls damp air and pollen directly from the ground, overwhelming filters and coating the blower motor in a gray paste that shortens its life.
- Disconnected flex duct in 1980s – 2000s attic retrofits. Flex duct sags under condensation, separates at the takeoffs, and dumps cooled air into a 130-degree attic. Homeowners end up running the AC harder while far rooms stay sticky. Sealing and re-hanging the runs fixes the airflow without replacing the whole system.
- Crushed or kinked original metal ducts in historic homes. In Norcross’s older homes, original metal runs get bent, kinked, or flattened over decades of service. The airflow drops, static pressure rises, and the air handler overheats and short-cycles. Repairing the run and sealing the joints restores the system’s breathing.
- Moisture-driven mold and pollen buildup in ductwork. Norcross’s hot, humid summers and heavy spring pollen mean duct interiors can grow biological material faster than they would in a drier climate. Sealing stops the outdoor air intrusion that feeds that growth. Cleaning is still needed first to remove what is already there.

FAQs About Duct Sealing in Norcross
Because the upstairs problem is usually not just leaks. In Norcross’s two-story homes, the real issue is often disconnected takeoffs in the attic or crushed runs where the duct passes through a tight chase. When we seal the joints but leave a collapsed run in place, the airflow never improves. A camera inspection before we seal shows us whether the ducts are open or collapsed. If they’re crushed, no amount of mastic will fix the airflow; the run has to be repaired or replaced first. Call (762) 769-7145 and we’ll help you figure out which one you have.
Yes, with careful handling. In Norcross’s historic downtown, technicians often find original galvanized ducts wrapped in asbestos tape. We do not disturb the wrap. We work around it, using methods that avoid grinding, cutting, or tearing the material. If the wrap is intact and the delivery is simply leaking at the joints, we seal outside the wrap and leave the material in place. If removal is ever necessary, a licensed abatement specialist does that part. We will tell you exactly what is needed after an inspection.
If your ducts are leaking, you’ll see specific signs beyond dust. Rooms that never match the thermostat setting, AC units that run constantly in July, humidity that stays high after the system cycles, and a crawlspace or attic that smells musty while the vents blow clean. Dirty ducts make the air dirty. Leaky ducts steal the air. In Norcross, the two often happen together, which is why we camera-inspect before recommending either sealing or cleaning. Call (762) 769-7145 and we’ll tell you what we find.
Sealing alone will not stop pollen from entering your home through open windows or on your clothes. But it does reduce pollen intrusion through the air system. Norcross’s spring pollen loads are heavy, and return-side leaks in crawlspaces can pull pollen directly into the blower and push it through every register. Sealing the returns stops that outdoor air from entering the conditioned space in the first place. It makes a real difference in how much yellow dust settles on your furniture each spring. Call us for an assessment.
That depends on the condition of the metal. In a 1960s brick ranch off Beaver Ruin Road, we found main supply ducts that had separated at the trunk, dumping conditioned air into the crawlspace. The metal was sound. We sealed every joint with mastic and fiberglass mesh and restored full airflow to the far bedrooms, no replacement needed. If the metal is rusted through, crushed flat, or full of sharp edges, replacement is the honest call. We’ll camera-inspect and show you what we see before recommending anything.
