The written price comes before any work starts, and it doesn’t move at the door. Call (229) 489-7780 for a straight answer and a free estimate.
Why Hollis Air Duct Sandy Springs Is Clarkston’s Preferred Duct Sealing Company
Clarkston’s building stock is specific: 1960s and 1970s low-rise apartments, modest brick ranches, flexible ductwork that’s been sagging since Nixon was in office. Generic duct sealing crews treat those buildings like any other suburb. We don’t. Our technicians arrive with long hose runs for restricted parking setups, camera inspection gear for finding leaks inside shared stacks, and the patience to work in buildings where residents speak a dozen languages and deserve a clear explanation before we touch anything. Roy Castellanos leads our team with a simple standard: show up when we said, price it in writing, seal it by the book, leave the site cleaner than we found it.
We also answer the phone. A live person, 24 hours a day, seven days a week. No voicemail loops. No “press 7 to hear options that don’t help you.” Clarkston property managers call us because when a unit’s ducts are leaking into another unit’s air, waiting until Monday isn’t acceptable. When you call (229) 489-7780, a real person picks up. That’s not a marketing line. That’s how we’ve run since day one, under The Garrison Standard: arrive inside the quoted window, price in writing, do the job by the book, leave the site clean.

HVAC Duct Sealing in Clarkston
HVAC Duct Sealing in Clarkston means closing every gap, crack, and separated joint in your supply and return duct system so the air your blower pushes actually reaches the rooms it’s intended for. In Clarkston’s older apartments and ranch homes, we typically find 20 to 30 percent of conditioned air escaping into attics, wall cavities, and crawl spaces before it ever hits a vent. You’re paying to cool the inside of a wall. Sealing stops that. A typical whole-system sealing job in Clarkston runs $800 to $1,400 for a single-family home between 1,200 and 2,000 square feet. For a single apartment unit with shared ducts, expect $400 to $700. The price is written down before we start. It doesn’t change.
Where We Find the Leaks
In Clarkston, we start at the air handler and work outward. Access panels near the blower, takeoff collars where branch ducts meet the main trunk, and every joint in flexible duct runs. Camera inspection shows us exactly what’s separated before we seal it, so you see what we see.
How We Seal It
We use HVAC mastic and metal-backed tape, not the gray hardware-store stuff that dries out and peels in two seasons. Mastic goes on as a paste and cures into a hard, airtight seal that handles the temperature swings of a Clarkston attic without cracking. It’s the same method commercial building codes require.
Duct Repair in Clarkston
Duct Repair in Clarkston goes beyond sealing holes. We’re talking about flex duct that has sagged so badly it’s pinched shut. Sections that have pulled completely apart at the takeoff. Insulation that’s soaked through from condensation and needs to be replaced. Clarkston’s humidity accelerates all of it. When the original flexible ductwork from a 1970s building finally gives out, sealing alone won’t fix it. The duct itself has to be replaced or re-supported. Duct repair work in Clarkston runs $600 to $1,800 depending on how much duct has failed, with full replacement of a trunk line in an attic running $1,200 to $2,500. We give you that range in writing before work begins, along with exactly what we’re replacing and why.
Sagging and Separation Repair
Flex duct that hangs loose in a hot attic loses its shape over time. We re-support it with proper strapping, reattach separated sections, and seal the connections. The difference in airflow is usually obvious the same day.
Insulation and Condensation Damage
When humid Georgia air hits cold duct surfaces, condensation forms. Over years, that moisture soaks into the fiberglass insulation jacket around the duct, collapsing it and exposing the metal or plastic core. We cut out the damaged section and replace it with new insulated flex duct, then seal both ends properly.
Common Duct Sealing Problems We See in Clarkston Homes
- Mastic failure from constant humidity. The original mastic on 50-year-old flex duct joints in Clarkston breaks down under year-round dampness. Condensation seeps into the insulation, the seal opens back up, and leaks reappear within a year of a cheap patch job. We use humidity-rated mastic and metal-backed tape that’s built for this climate, not for a dry garage in Phoenix.
- Shared exhaust stacks leaking between units. Garden apartments off North Indian Creek Drive and Brockett Road often share vertical exhaust stacks. Building settling opens gaps at floor-to-floor transitions, so a neighbor’s cooking smells and moisture drift into your unit through the duct. Sealing one unit without addressing the stack connection leaves the problem in place.
- Access panels knocked loose during equipment work. In Clarkston’s older buildings, the air handler closet is tight. Technicians moving equipment past the return plenum often bump the access panel and break its seal without noticing. We inspect and reseal those panels on every job because we know from experience they’re a recurring leak point.
- Cooking oil residue compromising old seals. We’ve pulled apart duct sections in Clarkston apartments where years of cooking oil vapor has deposited a sticky film on the interior. That film softens mastic over time. We clean the surfaces thoroughly before applying new sealant, otherwise the repair won’t hold.
Pricing for Duct Sealing in Clarkston, GA

A Problem That’s Specific to Clarkston
Here’s what makes Clarkston different from Stone Mountain or Smyrna when it comes to duct sealing. This city’s 1960s through 1980s garden apartments and brick ranches still have original flexible ductwork in a huge share of units. That duct was never designed for 50 years of Georgia humidity. The outer jacket breaks down. The inner liner separates. The joints where the flex meets the metal plenum sag open. When we seal ducts in Clarkston, we’re not just closing holes. We’re fighting back moisture-driven mold pressure that newer construction and drier climate cities never see to the same degree. The sealing material has to withstand condensation. The access has to work around tight attic stairs and shared mechanical closets. The job is different here, and anyone who tells you otherwise hasn’t done much work in this city.
At a low-rise apartment complex off North Indian Creek Drive, our crew sealed a stack of shared dryer vents and supply ducts in a 1970s building where cooking-oil residue had softened the mastic on original flex duct joints. We used a Rotobrush agitation system and camera inspection to locate every leak, then applied HVAC mastic and metal-backed tape to restore negative pressure across all units. That single job cut cross-contamination between apartments and dropped the blower motor’s runtime noticeably. The property manager noticed it on the next power bill. That’s the difference between sealing ducts the right way and just spraying some goo in a gap.
For property managers and homeowners in Clarkston, this is the guidance that actually applies to your buildings. Mid-century garden apartments with shared stacks and original flex duct need a different approach than a 2015 house in Roswell. We’ve been doing Duct Sealing long enough to know the difference, and we’ll tell you straight what your building needs.

FAQs About Duct Sealing in Clarkston
Clarkston’s garden apartments were built in the 1960s through 1980s with flexible ductwork that was never intended to last 50 years. Constant humidity from the subtropical climate softens original mastic at the joints, building settling pulls sections apart, and decades of accumulated dust and cooking oils degrade the material further. Newer buildings use rigid sheet metal duct and modern sealants that handle moisture far better. Call (229) 489-7780 for an evaluation of your specific building.
We work from the access points that already exist: air handler closets, attic scuttles, and crawl space entries. We don’t cut into walls unless a duct has collapsed completely and there’s no other access, which is rare. Our crews use long hose runs to reach tight mechanical rooms through narrow interior stairs without dragging equipment through living areas. We let property managers know what we’re doing and keep noise to working hours. The point is to fix the duct, not remodel the building.
Yes, when the smell is traveling through leaks in a shared exhaust stack or gaps between floor-to-floor transitions. Sealing those connections stops the air path that carries odors from one unit to another. However, if the smell is coming through the walls themselves or shared bathroom vents, duct sealing addresses part of the problem but not all of it. We’ll inspect and tell you honestly what’s moving through the ducts and what isn’t. Call (229) 489-7780 to schedule an inspection.
Yes. If you’re a tenant in a Clarkston apartment, we need written permission from the property manager or owner before we begin work on shared building components. Ductwork behind walls and through floor transitions belongs to the building, not the individual unit. Most Clarkston property managers know us already and can approve work quickly. If you rent a single-family home, the owner still needs to authorize the work. Call it professional courtesy and self-protection: you don’t want a lease violation over an unauthorized repair. Call (229) 489-7780 and we can talk through how to get the approval moving.
Duct cleaning removes built-up debris, mold, and dust from the inside of the ducts. Duct sealing closes the leaks where air escapes. In a Clarkston ranch house with high humidity, you often need both: cleaning first to remove the moisture-damaged material, then sealing to stop more humid air from getting pulled into the system. Cleaning alone leaves the leaks open, and sealing alone traps whatever is already inside. We price both separately and recommend what your system actually needs, not what makes our invoice bigger. Call (229) 489-7780 for a straight recommendation.
