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.

Call (470) 326-1926 for a written estimate before any work starts.
We’ve worked in Norcross since 2013, and the housing stock here tells a specific story. The 1970s-1980s ranch and split-level tracts near Holcomb Bridge Road, the garden-style complexes along Jimmy Carter Boulevard, and the older homes in Old Town all carry duct systems built for a different era of energy costs and materials. That history matters when we’re deciding whether a deteriorated flex-duct run can withstand standard agitation or needs gentler handling under negative pressure.
Why CleanRun Air Duct Cleaning Johns Creek Is Norcross’s Preferred Duct Repair & Sealing Company
Our Duct Repair & Sealing team has documented photo records from over 1,200 jobs in Norcross and the surrounding Gwinnett County corridor. Homeowners here tend to research before calling, and they ask the right questions: what equipment will you use, what’s the written price, and what do I actually get when you leave. We answer all three before a panel comes off.
Reviews from Norcross customers consistently mention two things: the before-and-after photo record delivered at job completion, and the written price that matched the final invoice. Haven Standard Clause 1 requires it. No one in our crew works from verbal estimates.
Response time to Norcross is typically two to three business days for standard scheduling, with dispatch coordinated from our Atlanta office. Crews are background-checked, uniformed, and identified by name before arrival, per Haven Standard Clause 3: Verified Crews.
We know the local conditions that break ductwork here: the Georgia Piedmont humidity that keeps AC running May through September, the clay dust from unpaved rural roads, and the wood-heat ash that migrates through systems differently than standard household dust. That local knowledge changes how we inspect, how we clean, and what we recommend for repair.
Our Duct Repair & Sealing Services in Norcross

Flex Duct Repair
Flex-duct systems dominate Norcross’s 1970s-1980s housing stock, and they’re now 35-45 years old. The plastic liner degrades, the wire helix corrodes, and the insulation compacts. In rural pockets around Norcross, we’ve found collapsed segments in outbuildings where no one had inspected the run since installation, causing total airflow loss to those zones. We replace damaged sections with new flex-duct rated for the application, support it properly to prevent sagging, and seal all connections with mastic. A typical flex-duct repair in Norcross runs $180-$340 per run, with written pricing delivered before work begins.

Duct Sealing
Leaky ducts are the norm in older Norcross homes, not the exception. The combination of wood-heat cycling and Georgia humidity expansion and contraction pulls joints apart at plenum connections, especially in systems that were never properly sealed at installation. We seal accessible joints with mastic sealant, not tape, and we photograph every connection before and after. Mastic sealing for a typical Norcross home runs $400-$650 for accessible ductwork. If we find biological growth during the inspection, we’ll document it and recommend appropriate remediation before sealing traps it inside.

Metal Duct Repair
Older homes in Norcross’s Old Town historic district and some commercial conversions still use galvanized metal ductwork. These systems can last decades but suffer from corrosion at seams, disconnected joints from vibration, and failed supports. We repair metal ducts with proper sheet-metal techniques, seal with mastic, and insulate where needed. Metal duct repair in Norcross typically runs $320-$580 depending on access and extent of damage.

Duct Insulation
Uninsulated or degraded duct insulation is common in Norcross crawlspaces and attics, where summer attic temperatures exceed 130°F and winter crawlspace humidity promotes condensation. We replace insulation with materials appropriate for the location and seal the vapor barrier. Duct insulation work in Norcross generally runs $450-$850 for a typical residential system.

Air Leak Repair
Air leak repair goes beyond sealing accessible joints. We pressurize the system, identify leakage points with smoke or theatrical fog, and repair them systematically. In Norcross’s older apartment complexes off Jimmy Carter Boulevard, we frequently find that conditioned air has been escaping into wall cavities for years, meaning tenants paid to cool and heat spaces that never received airflow. Air leak repair and verification in Norcross typically runs $350-$700.

Common Duct Repair & Sealing Problems We See in Norcross Homes

- Flex-duct joints pulled apart at plenum connections. Years of wood-heat cycling and Georgia Piedmont humidity swings expand and contract the connections until they separate. Conditioned air escapes into crawlspaces while the system runs longer to compensate.
- Collapsed flex-duct segments in rural outbuildings. Properties on unpaved roads around Norcross often have shop or garage HVAC extensions that were installed and forgotten. The ductwork collapses under its own weight or from pest intrusion, and no one notices until that zone stops heating or cooling entirely.
- Mold colonization on duct-board interiors. Norcross’s sustained condensation cycling, May through September, creates ideal conditions for biological growth in aging duct-board systems. Homeowners often mistake the musty odor for simple dust buildup until a camera inspection reveals the actual condition.
- Fine ash and creosote-laden soot from wood heat. In Norcross’s rural pockets and older homes, secondary wood heat loads ductwork with particulate that behaves differently than standard dust. It migrates into the air handler and blower motor compartment, accelerating wear and reducing efficiency.

FAQs - Duct Repair & Sealing in Norcross

Every two to three years for homes on unpaved roads, compared to three to five years for paved-road properties. The clay dust from Norcross’s unpaved rural roads loads filters and ductwork faster than standard particulate, and that dust is finer and more abrasive than typical household debris. If you also burn wood seasonally, inspect annually and clean every two years. Call (470) 326-1926 for a written inspection quote.
Yes. Wood-heat ash and creosote-laden soot require slower, lower-agitation cleaning under negative pressure to avoid mobilizing fine particulate into the living space. We were called to a 1970s split-level off Holcomb Bridge Road where the homeowner burned wood most winters. Our tech ran a camera inspection and found flex-duct runs coated in fine ash that had migrated into the air handler and blower motor compartment. We used agitation tools at low speed to avoid tearing the aged flex liner, then sealed several pulled-apart joints with mastic sealant and rebalanced the supply and return ducts. Airflow at the registers improved noticeably. The photo record documented every stage.
The 1970s-1980s flex-duct and duct-board systems standard in Norcross’s build era were never designed for 35-45 years of continuous use. The plastic liner becomes brittle, the wire helix corrodes, and the fiberglass insulation compacts or detaches. Combined with Georgia Piedmont humidity cycling and wood-heat thermal stress, these systems fail at joints and sag points far more frequently than modern ductwork. We inspect before we clean. Aggressive extraction on deteriorated material can tear the liner and make a repair job into a replacement job.
Yes, and we frequently do. Outbuilding systems are often the most neglected ductwork on the property, with collapsed runs, disconnected joints, and no filter maintenance. We inspect with a camera first, document the condition, and provide a written price for cleaning, repair, or replacement before any work starts. Outbuilding ductwork in Norcross typically requires more labor due to access constraints and the extent of deterioration.
Every two years for rental properties with high turnover, especially the garden-style apartment complexes along Jimmy Carter Boulevard where tenant debris accumulates across multiple occupancy cycles. Each tenant introduces new particulate, and with one of Gwinnett County’s highest renter-to-owner ratios, these properties routinely accumulate multiple tenants’ worth of debris, Georgia red-clay dust, and mold before any duct cleaning is performed. Property managers should budget for systematic duct inspection and cleaning as part of unit turnover, not as a reactive repair. Call (470) 326-1926 for multi-unit pricing.
