Our Clarkston crews dispatch from the Atlanta office and know the local housing stock: low-rise brick apartments built in the 1970s and 1980s, small ranch homes converted to multi-family rentals, and the specific failure patterns that come with decades of tenant turnover and absentee landlords. We’ve sealed ducts in units where the original galvanized steel trunk lines are still in place, flex duct has sagged between floors, and bathroom exhausts have been illegally tied into the return plenum. That local knowledge matters because sealing Clarkston ductwork correctly means finding problems that aren’t on the standard checklist.

Why Hollis Air Duct Cleaning Is Clarkston’s Preferred Duct Sealing Company

We’ve been part of the Garrison Partners family since 2004, and our Duct Sealing team serves Clarkston under The Garrison Standard: arrive inside the quoted window, price in writing before touching equipment, complete the job by the book, and leave the site clean. That standard was built for customers who’ve been burned by no-shows and ballooning invoices.

Our technicians are background-checked and uniformed – you know who’s walking into your home before they arrive. Every duct sealing job in Clarkston carries our 365-Day Done Right Promise in writing: if the seal fails or the problem returns within a year, we come back and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday for someone to pick up.

Clarkston’s refugee-dense, fast-turnover housing market creates unique conditions. Families often move into units that haven’t been serviced in decades, and language barriers mean written documentation and visual proof matter as much as the work itself. We explain what we found, show camera footage, and put the scope and price on paper before we start. That’s how we’ve built repeat relationships with property managers and individual tenants across Clarkston’s apartment corridors.

Duct Sealing Services in Clarkston

Duct Sealing Services in Clarkston address the specific leaks, disconnections, and code violations found in aging apartment complexes and converted ranch homes where original ductwork has degraded through decades of use. The job involves pressurizing the system to locate leaks, sealing joints and plenums with mastic and fiberglass mesh, reconnecting separated flex duct, and documenting the repair with camera inspection. A typical single-system residential sealing in Clarkston runs $450 – $750; multi-system homes or apartments with illegal cross-connections requiring separation run $650 – $950. Most jobs take 3 – 5 hours.

Leak Detection and Mastic Sealing

We pressurize your duct system and use smoke pencils or digital manometers to find every leak, not just the obvious ones. In Clarkston’s 1970s galvanized steel trunks, we find separated joints at the air handler plenum, gaps where supports have failed, and holes from decades of vibration. We seal with water-based mastic and reinforced mesh, not tape that will dry and fall off in Georgia’s humidity. The seal is rated for the temperature swings your attic or crawlspace sees.

Illegal Cross-Connection Separation

In the apartment clusters off Indian Creek Drive, we routinely find dryer vents and bathroom exhausts illegally tapped into the central return ductwork, which is why our Dryer Vent Cleaning in Clarkston also addresses proper exhaust routing. This pulls lint and moisture straight back into your living space, feeds mold growth, and overloads your HVAC with humidity. Separating these connections is not optional – it’s part of proper duct sealing in Clarkston. We cap the illegal taps, restore proper exhaust routing, and document the repair with before-and-after camera footage.

Duct Insulation in Clarkston

Duct Insulation in Clarkston protects sealed ductwork from the attic heat and crawlspace moisture that degrade performance in Georgia’s climate. Uninsulated or poorly insulated ducts in a 140-degree Clarkston attic can lose 10 – 15% of cooling capacity before the air reaches your vents. We install foil-faced fiberglass insulation or closed-cell foam wraps over sealed ducts, with particular attention to flex duct runs that pass through unconditioned spaces. Typical duct insulation in Clarkston runs $300 – $600 for a single system when combined with sealing, or $400 – $800 as a standalone job.

Attic and Crawlspace Wrap Installation

Clarkston’s older ranch homes and converted apartments often have duct runs through vented crawlspaces or low attics where summer heat and winter cold extremes hit hard. We wrap sealed ducts with insulation rated for the application, seal the insulation seams with matching tape, and secure it so it won’t sag or compress. Proper insulation means your HVAC doesn’t work overtime to compensate for thermal loss.

Condensation Control

Hot, humid Georgia summers mean cold supply ducts in unconditioned spaces sweat. That moisture drips onto ceilings, feeds mold in crawlspaces, and degrades the very seals we just installed. Our insulation includes vapor barrier placement calculated for Clarkston’s humidity levels, reducing condensation that would otherwise undo your sealing investment within a season or two.

Trusted Brands We Service in Clarkston

We seal and insulate duct systems connected to all major HVAC brands, and we stock parts and materials for fast turnaround on Clarkston jobs. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines for pre-sealing cleaning, plus sealing and filtration products from Abatement Technologies and Guardsman. When we find a failed flex duct section or a damaged plenum that needs replacement during a Clarkston sealing job, we don’t wait on a parts order – we carry the materials to complete the repair same visit. That’s the difference between a crew that seals what they find and a crew that seals what they planned to find.

Common Duct Sealing Problems We See in Clarkston Homes

• Illegal dryer vent and bathroom exhaust cross-connections. In the dense apartment clusters off Indian Creek Drive, we regularly find dryer vents and bathroom fans tapped into the central return ductwork. This is a code violation that feeds lint and moisture back into living spaces, and sealing without separating these connections just traps the problem inside the system.
• Sagging, torn flex duct patched with tape. Clarkston’s 1970s – 80s apartment runs often use flex duct that has sagged between supports, torn at connections, or been repeatedly patched with duct tape that degrades in attic heat. Tape-over-tape sealing fails within months; proper repair requires reconnecting or replacing damaged sections and sealing with mastic.
• Unsealed air handler plenums and trunk line joints. Original galvanized steel ductwork in Clarkston’s older housing stock was assembled with snap-lock seams and drive cleats, not sealed joints. Decades of thermal cycling have opened gaps at the plenum, trunk line connections, and register boots that leak conditioned air into attics and crawlspaces.
• Missing or failed insulation on sealed ducts. Even properly sealed ducts lose efficiency in Clarkston’s hot attics and humid crawlspaces when insulation has fallen away, been compressed by maintenance activity, or was never installed. We inspect insulation condition as part of every sealing evaluation.
