You’re not calling for a sales pitch. You’re calling because something’s wrong with the air moving through your house, and you want a straight answer about what it costs to fix. That’s what we do.

Why Hollis Air Duct Sandy Springs Is Sandy Springs’s Preferred Duct Sealing Company

We’ve been sealing ducts in Sandy Springs long enough to know exactly what we’ll find before we open a single access panel. The housing stock here tells a story: brick and frame homes from the 1970s through the 1990s, many with original flex duct that’s now sagging, separated, or pulling damp crawlspace air into the system. Newer custom builds near the river have their own issues, usually condensation inside plenums where humid air meets cold metal.

Roy Castellanos runs our Sandy Springs operation, and he holds every technician to The Garrison Code: arrive inside the quoted window, price the job in writing before any work starts, do it by the book, and leave the site cleaner than we found it. No exceptions. If you call our number, a live person answers. Not a voicemail loop. Not a callback queue at 9am Monday. That matters when you’re standing in a humid house wondering why the air smells like a crawlspace.

Every duct sealing job we do in Sandy Springs is covered by the 365-Day Done Right Promise. If a sealed joint fails within a year, we come back and fix it at no charge. That’s written on every invoice, not implied in a handshake.

Air Duct Sealing in Sandy Springs

Air Duct Sealing in Sandy Springs means closing every leak in your duct system so conditioned air goes where it’s supposed to go, not into your attic, crawlspace, or wall cavities. We use mastic sealant applied with a brush – not tape, which dries out and peels in the heat and humidity this city throws at it. The job usually takes four to eight hours depending on home size and access.

Sandy Springs homeowners call us when they notice rooms that never reach the thermostat setting, dust appearing on furniture days after cleaning, or a smell that comes and goes with the AC cycle. The fix is often less expensive than people expect because the real problem is rarely the whole system. It’s usually specific failure points: a separated return plenum, a crushed flex run, a boot that was never seated correctly.

Whole-Home Leak Sealing

We seal supply and return runs from the air handler to every register boot. That includes joints, seams, and any place metal meets flex duct. In Sandy Springs homes with crawlspace-mounted air handlers, this almost always means sealing the entire return path, because that’s where moisture enters the system.

Return Path Repair

When the return side leaks, your system pulls air from wherever it can get it. In a Sandy Springs crawlspace, that’s humid red-clay air full of mold spores. Sealing the return path stops that at the source and costs $350 to $800 on its own for most homes.

Duct Sealing Services in Sandy Springs

Duct Sealing Services in Sandy Springs include camera inspection to find the leaks, negative pressure testing to confirm them, then mastic sealing and insulation wrap where needed. We don’t guess. We show you the before-and-after photos of your own ducts so you know the work happened. If we’re already in your system for a cleaning, we’ll flag sealing issues as part of the service, not as an upsell.

What drives cost here: how many linear feet of duct need sealing, whether we’re working in a tight crawlspace or a walkable attic, and how bad the existing duct material is. Homes near the Chattahoochee River corridor tend to need more return-side work because humidity finds every gap.

Sealing After Duct Cleaning

If you’re having your ducts cleaned, that’s the ideal time to seal them. The system is open, we can see every joint, and the mastic goes on clean metal or flex rather than trying to stick through dust. Most Sandy Springs customers combine the two jobs and save on the second trip charge.

Air Handler and Plenum Sealing

The air handler cabinet and the plenums above and below it are the most common leak points we find in Sandy Springs. Metal cabinets with loose seams, flex duct attached to sheet metal with nothing but a zip tie, return boxes that were never sealed at all. We seal these with mastic and reinforce with mechanical fasteners where the original install was sloppy.

Trusted Brands We Service in Sandy Springs

We service and seal ductwork from every major manufacturer, including systems built around Rotobrush and Nikro equipment, and we pair sealing work with filtration from Guardsman and Abatement Technologies when a Sandy Springs home needs better air quality after the leaks are closed. Because we work on these systems day in and day out, we stock common fittings and sealants on our trucks, which means fewer return trips and a faster job for you. We don’t sell one brand. We fix what’s in your house and tell you straight if sealing is worth doing or if the duct itself needs replacement instead.

Our Duct Sealing team sees every brand combination there is, so when you call about a specific issue, you’re talking to someone who knows what your setup looks like before they even arrive in Sandy Springs.

Common Duct Sealing Problems We See in Sandy Springs Homes

• Original flex duct from the 1980s that’s sagged and separated. Homes built east of Roswell Road in the 1980s almost always have original flex runs by now. We routinely find runs that have pulled loose from boots or separated at the trunk line, dumping conditioned air into attics and crawlspaces.
• Crawlspace-mounted air handlers pulling damp air through unsealed returns. The red-clay soil under Sandy Springs crawlspaces stays damp most of the year. An unsealed return plenum acts like a vacuum, pulling that moisture straight into your system and through your house.
• Condensation inside plenums near the river. Homes in Riverside and Heards Ferry sit close enough to the Chattahoochee that humidity stays elevated even in winter. Cold supply air moving through a warm, humid attic creates condensation inside unsealed plenums, which leads to mold growth that cleaning alone won’t stop.
• Red-clay dust and pine pollen infiltrating through gaps. Sandy Springs has a dense tree canopy, and that means heavy pollen seasons. Leaky ducts actively pull that fine particulate into your system, where it coats the blower motor and clogs registers faster than in drier parts of metro Atlanta.
