Our Duct Repair & Sealing Services in Peachtree Corners
Duct Sealing
Most Peachtree Corners homes lose 20-30% of conditioned air through leaks at joints, plenum connections, and register boots. In two-story colonials near Simpsonwood Park, we often find the upstairs trunk line pulling away from the main plenum - a gap that costs you every month but shows no visible symptom until we camera it. We seal with mastic and reinforced mesh, not tape that dries and fails. A typical duct sealing job in Peachtree Corners runs $280-$450 for a single system.

Flex Duct Repair
The flex duct installed in Peachtree Corners’s original construction wave was builder-grade, with inner liner seams that fail predictably after four decades. We replace damaged flex runs with new, properly supported flex duct - sagging kills airflow - and seal connections with mechanical fasteners plus mastic. Flex duct repair in Peachtree Corners typically ranges $180-$340 per run, depending on attic access and length.

Metal Duct Repair
Some Peachtree Corners homes, particularly later builds near the Forum, have galvanized metal trunk lines. We repair rusted sections, reseal joints, and reinforce sagging supports. Metal work runs higher - $340-$620 - but properly maintained metal ductwork outlasts any alternative.

Duct Insulation
Uninsulated or degraded duct insulation in Peachtree Corners attics wastes energy every summer when attic temperatures hit 140°F. We wrap with formaldehyde-free fiberglass or foil-faced bubble wrap, depending on clearance and code. Insulation work typically adds $150-$280 to a sealing job.

Mastic Sealant Application
Mastic is our standard for every Peachtree Corners job - brushed or sprayed onto joints and seams, then reinforced with mesh for structural integrity. Unlike foil tape, mastic stays flexible and seals permanently. We apply it to plenum connections, register boots, and any repair junction. It’s labor-intensive. It’s the only way we’d do it on our own homes.

Air Leak Repair
Return-air leaks in Peachtree Corners homes are especially problematic given the pollen load from those oaks and pines. A leaky return pulls unfiltered attic air directly into your system, bypassing the filter entirely. We pressure-test, locate, and seal - restoring the barrier your HVAC was designed to maintain.

Common Duct Repair & Sealing Problems We See in Peachtree Corners Homes
- Fiberglass duct board delamination. The interior liner in original 30092 duct systems separates after decades of Gwinnett humidity, shedding glass fibers into airflow. We inspect liner condition before any cleaning begins - cleaning a delaminated system makes it worse.
- Failed flex duct inner liner seams. Early-generation flex duct in Peachtree Corners’s 1970s-80s builds develops longitudinal splits in the inner liner. Air blows between liner and insulation, never reaching the room. Energy bill climbs. Comfort drops.
- Pollen-choked return-air pathways. The dense tree canopy that makes Peachtree Corners attractive also delivers massive spring pollen loads. Returns clog, systems strain, and mold finds footholds in the chronic moisture of aging duct board.
- Disconnected register boots and plenum gaps. Thermal cycling and settling in 40-year-old homes loosen critical junctions. We camera-verify every connection before we close up.

FAQs - Duct Repair & Sealing in Peachtree Corners
Peachtree Corners was developed as one of Georgia’s first large master-planned communities, with the bulk of its residential neighborhoods built out between the late 1960s and mid-1980s alongside Technology Park Atlanta. This means a concentrated cohort of 30092-ZIP homes are running on 40- to 50-year-old duct systems - frequently original fiberglass duct board or early flex duct that has degraded in Georgia’s relentless humidity - creating a neighborhood-wide remediation need that simply does not exist in younger adjacent suburbs like Johns Creek or Suwanee. We serviced a ranch-style home on Tree Lane in Peachtree Corners where the original fiberglass duct board interior liner had completely delaminated due to decades of Gwinnett humidity. After a full inspection, we sealed the deteriorating sections with mastic and replaced the damaged flex duct connections, restoring airflow and eliminating fiber contamination. Call (855) 305-5564 if your home dates to this era - we’ll camera-inspect before any work begins.
Signs include visible dust that sparkles under light, increased allergy symptoms when the system runs, or a technician’s camera showing fuzzy liner separation inside the duct. We encounter this regularly in Peachtree Corners - the combination of 1970s-80s construction vintage and Gwinnett’s moisture levels creates a failure mode rarely seen in newer suburbs. Do not run the system if you suspect active delamination; disturbed fibers circulate continuously. Call (855) 305-5564 for a camera inspection - we’ll show you exactly what we’re seeing.
No. Failed inner liner seams in original flex duct require section replacement - sealing the outer insulation does nothing to restore airflow through the inner liner. We see this distinction confuse homeowners who’ve had “sealing” quotes from companies that never camera-inspected. A proper Peachtree Corners assessment separates true leaks from structural flex failures. We quote each condition honestly. Call (855) 305-5564 for a free second opinion if you’ve received a conflicting diagnosis.
Mastic sealant with embedded reinforcement mesh, applied to structurally sound duct board after removing loose liner. Where liner has fully delaminated, we replace the section with new duct board or transition to metal - never cover over active fiber shedding. In Peachtree Corners’s humid climate, tape-based repairs fail within seasons. Mastic remains flexible and seals permanently. We use Nikro application equipment for consistent coverage. Material choice matters here more than in drier climates.
Repair first, always - especially in Peachtree Corners’s aging housing stock. Cleaning a system with delaminated liner or open flex seams forces debris deeper into damaged areas and can accelerate fiber release. We camera-inspect every Peachtree Corners system before recommending any service sequence. If your home was built in the 1970s-1980s, assume repair assessment comes first. Call (855) 305-5564 to schedule - estimates are free, and we’ll sequence the work correctly.
If your Peachtree Corners home was built in the community’s original wave, your ductwork is likely past its design life. We’re not going to tell you it’s fine when it isn’t, and we’re not going to sell you cleaning when you need repair. One honest price, shown before we start. Camera verification every time. And if something’s not right, we stand behind it - no paperwork, no arguing - for 90 days.
