Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Why CleanRun Air Duct Cleaning Marietta Is Holly Springs’s Preferred Duct Repair & Sealing Company
Our Duct Repair & Sealing team has documented work in Holly Springs subdivisions since 2013, and the pattern is remarkably consistent: 15-25 year old attic flex duct, original builder-grade hangers, and pollen debris loads that outpace what we see closer to Atlanta. That consistency means we arrive knowing what to inspect first.

The 365-Day Done Right Promise is backed in writing on every job, not offered as a verbal afterthought.

Our Duct Repair & Sealing Services in Holly Springs
Duct Sealing
Duct sealing in Holly Springs addresses the joint separations that develop after 15-20 years of thermal cycling in hot attics. We use mastic sealant, not tape, at every connection point - mastic remains flexible and airtight where foil tape dries and fails. A typical Holly Springs duct sealing job runs $450-$850 for a full system, depending on the number of runs and the accessibility of the plenum (the main distribution box, where all your duct runs connect). Every sealed joint is photographed before and after as part of the standard Documented Photo Record.
Flex Duct Repair
Flex duct repair is the most common service we perform in Holly Springs. The 2000s-2010s build-out here used flexible ductwork almost exclusively for attic runs, and those runs are now hitting the age where hangers fail, sags develop, and the inner liner tears at stress points. Repair costs $180-$340 per run, including re-support, section replacement where needed, and reconnection to the plenum. We use professional-grade materials - Guardsman flex duct and Nikro HEPA-negative-pressure equipment during the repair process to protect your home’s air quality while we’re working.
Metal Duct Repair
Metal duct repair in Holly Springs is less common than flex work but shows up in older custom homes and in the transition sections near air handlers. Rust-through at condensate collection points, separated seams from thermal expansion, and damaged take-off collars are typical issues. Metal repair runs $220-$480 depending on access and the extent of section replacement. We fabricate replacement sections on-site when possible to minimize return visits.
Duct Insulation
Duct insulation in Holly Springs addresses a problem specific to our Cherokee County foothills climate: summer condensation inside poorly insulated attic flex duct. The humid subtropical air hits the cool duct surface and sweats, creating conditions for mold that joint sealing alone won’t fix. Insulation replacement or augmentation runs $320-$580 for typical systems, using materials rated for attic temperatures that regularly exceed 130°F in July. Proper insulation also reduces the cooling load on your HVAC system, which matters when you’re running AC from May through September.

Common Duct Repair & Sealing Problems We See in Holly Springs Homes
- Sagged flex duct bellies from failed hangers. The original plastic straps used in 2000s-2010s Holly Springs construction degrade in attic heat. Undersupported hangers let the duct belly downward, creating low spots where red Georgia clay dust, blown-in insulation fibers, and pollen debris collect. A single vacuum pass won’t clear these - the section must be re-supported and the debris agitated out under negative pressure.
- Pollen debris coating beyond what filters catch. Holly Springs sits in one of the highest tree-pollen-load corridors in the country. Spring pine and oak pollen overwhelms standard 1-inch pleated filters within days, and the fine particles that pass through settle in duct interiors. Filter changes help but don’t eliminate the buildup that requires professional cleaning and sealing.
- Condensation-related mold in poorly insulated runs. The combination of humid subtropical summers and 130°F+ attic temperatures creates persistent condensation on under-insulated flex duct. Surface mold develops at the condensation points, particularly where the duct sags and airflow stagnates. Sealing without insulation correction leaves the root cause active.
- Joint separations at plenum connections. Thermal cycling over 15-20 years loosens the mechanical connections between flex duct and the plenum. Conditioned air leaks into the attic before reaching your registers, raising energy bills and reducing comfort. Mastic sealing restores the airtight connection and is photographed for your record.

FAQs - Duct Repair & Sealing in Holly Springs
Every 3-5 years for Holly Springs homes with 2000s-era attic flex duct, with sealing inspection every 2-3 years if you’re seeing energy bill increases or room-to-room temperature differences. The combination of severe foothills pollen and rural dust from unpaved roads and open land means ducts here load faster than in denser suburbs. Homes on gravel roads or with significant tree-line exposure should lean toward the shorter interval. Call (470) 516-9337 and we’ll camera-inspect your system to give you a specific interval based on what we find.
The original plastic hanger straps installed during the 2000s-2010s construction boom degrade in sustained attic heat above 130°F. Once a strap fails, the flex duct belly sags, trapping debris and restricting airflow. In Harmony on the Lakes and similar subdivisions, we find this on the majority of first-time service calls. Re-supporting the run with proper metal strap and correcting the sag restores both airflow and long-term durability. The correction is photographed before and after for your record.
Yes. Holly Springs’s Cherokee County foothills location creates one of the most severe spring pollen environments in the country. Standard 1-inch filters load within days during peak pine and oak season, and the fine particles that bypass the filter settle in duct interiors. We’ve photographed duct runs in Holly Springs with visible pollen debris accumulation at elbows and low points. Professional cleaning removes this buildup; proper sealing prevents re-entrainment from attic leaks.
A standard visit includes: camera inspection of accessible duct runs to map damage and debris locations; written price delivered before work begins; debris removal using agitation tools under HEPA-negative-pressure extraction; repair or replacement of damaged flex or metal sections; mastic sealing of all accessible joints; re-support of sagged runs; static pressure verification at the air handler; and a Documented Photo Record of every run, before and after, delivered to you as part of the job file. The 365-Day Done Right Promise covers all work in writing.
Yes, we service outbuilding and detached garage HVAC systems in Holly Springs, including the rural properties on larger lots toward the county line. These systems face amplified dust loading from unpaved driveways and open land, and they often use the same flex duct methods as the main house but with less frequent maintenance attention. We apply the same written-price-first protocol and photo documentation. Note that longer service drives to outlying properties may affect scheduling; mention the detached system when you call (470) 516-9337 so we route the appropriate crew and equipment.
