Trusted Duct Repair & Sealing for Atlanta Homeowners
Our Affordable Duct Repair & Sealing in Atlanta, GA typically runs between $250 and $850 depending on the scope, with most jobs completed in a single visit by our background-checked technicians. If your upstairs rooms never cool down, your energy bills keep climbing, or you’ve noticed musty air coming from certain vents, the problem is likely leaks or damage in your ductwork. We’ve been fixing ducts across Atlanta since 1984, and we answer our phones live, 24 hours a day. Call (855) 305-5564 for a free estimate with upfront pricing - the number we quote is the number on your invoice.
Atlanta’s hot, humid summers and occasional hard freezes put serious stress on duct systems. In neighborhoods like Druid Hills and Brookhaven, we regularly find original galvanized ductwork from the 1960s and 1970s that’s rusted through at the seams, which is why homeowners there trust our Duct Repair & Sealing in Druid Hills. In Sandy Springs and North Atlanta, flex ducts in attics have been chewed by squirrels or crushed by workmen crawling over them. Wherever you are in the metro area, we bring the same approach: camera inspection before we start, camera verification after we finish, and a 90-Day Done Right Promise in writing. Cliff Darden has built this company on the idea that a homeowner should never have to call a contractor back to fix the same problem twice.
What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, cracks, and disconnected joints that let conditioned air escape into your attic, crawl space, or walls. In Atlanta, where attic temperatures can hit 140 degrees in July, every cubic foot of cooled air that leaks out is money you’re paying to cool your roof shingles. We use a combination of mastic sealant and metal-backed tape, applied after we’ve inspected every joint with a borescope camera. The result is a system that delivers the air you’re paying for to the rooms where you actually live.
Flex Duct Repair
Flex duct is the ribbed, insulated tubing common in Atlanta homes built after 1980, and it’s vulnerable to crushing, kinking, and damage from pests. We’ve replaced flex duct in Austell that raccoons had torn open for nesting material, and in Fair Oaks we found sections that had been pinched during a water heater installation years earlier. Our technicians carry replacement flex duct in standard diameters, along with the proper supports and connectors to ensure full airflow without sagging or restriction. Most flex duct repairs are done in under two hours.
Metal Duct Repair
Galvanized steel and aluminum ductwork lasts longer than flex but corrodes at seams and can separate at joints due to thermal expansion. In older Atlanta homes near Mableton and Marietta, we see metal ducts that have rusted through from decades of condensation. We cut out damaged sections, fabricate replacement pieces on site, and seal with mastic rather than relying on tape alone. For ductwork that’s structurally sound but leaking, we often recommend Aeroseal or manual sealing to restore efficiency without a full replacement.
Duct Insulation
Uninsulated or poorly insulated ducts in Atlanta attics lose massive amounts of energy, and in humid months they sweat, leading to mold and water damage. We install foil-faced fiberglass insulation or closed-cell foam wrap, depending on the application and your existing system. In North Druid Hills, we recently reinsulated a trunk line that had been sweating onto ceiling drywall, causing a stain the homeowner had blamed on a roof leak. Proper insulation pays for itself in comfort and protection against bigger problems.
Mastic Sealant
Mastic is a thick, fiber-reinforced paste that we brush or trowel onto duct seams - it outlasts duct tape by decades and forms a permanent, flexible seal. We apply mastic to every new joint we create and to existing joints that show leakage during our pressure test. Unlike foil tape, which can dry out and peel, mastic remains pliable and airtight through thousands of heating and cooling cycles. It’s the standard we learned 42 years ago, and it’s still the right way to seal ductwork.
Air Leak Repair
Air leaks are the silent thief of comfort and money, often wasting 20 to 30 percent of the air your HVAC system produces. We locate leaks using a combination of visual inspection, blower door testing, and thermal imaging to find the gaps that aren’t obvious. In Vinings, we found a disconnected return duct that was pulling 120-degree attic air straight into the system, making the air conditioner run constantly. Once sealed, the homeowner’s upstairs bedrooms finally cooled to the thermostat setpoint.

Brands We Service for Duct Repair & Sealing
We’ve worked on duct systems connected to virtually every HVAC brand sold in Atlanta over the past four decades. Our technicians regularly service ductwork paired with Honeywell zoning systems, and we understand how their dampers and bypass ducts integrate with the overall airflow design. We’ve also repaired and sealed ducts serving Aprilaire whole-house dehumidifiers, which are common in Buckhead and Sandy Springs basements where humidity control is critical. Our trucks carry the fittings and adapters to interface with these systems without improvisation.
We also have deep experience with Nikro duct cleaning and repair equipment, and we’ve serviced many homes with Abatement Technologies HEPA filtration systems where maintaining duct integrity is essential for proper air quality. Whether your system is paired with Honeywell, Aprilaire, or any other make, we can assess the ductwork, identify the leaks or damage, and fix it so the equipment you invested in performs the way it was designed to.
Signs You Need Duct Repair & Sealing Right Now
- Rooms that never reach the set temperature. If your master bedroom stays five degrees warmer than the thermostat reading while the basement is an icebox, conditioned air is escaping before it reaches its destination. We see this constantly in two-story Atlanta homes where a disconnected duct in the attic sends all the cooling to one side of the house.
- Dust that returns within days of cleaning. Leaky return ducts pull air from your attic or crawl space, and that air carries fiberglass particles, pollen, and rodent droppings straight into your living space. If you’re dusting more often than you used to, your ducts are likely the culprit.
- Unexplained spikes in your energy bill. When 25 percent of your cooled air leaks into the attic, your system runs longer to achieve the same result. We’ve had Atlanta homeowners call us after summer bills jumped $80 to $120 month over month, and duct sealing brought them right back down.
- Musty or stale odors when the system runs. Leaks in return ducts can pull musty air from crawl spaces, and leaks in supply ducts can create negative pressure that draws odors through wall cavities. Either way, the smell is a sign that your ductwork is communicating with spaces it shouldn’t be.
- Visible damage in accessible areas. If you can see crushed, disconnected, or rusted ductwork in your attic or basement, the hidden portions are almost certainly worse. We offer free inspections with camera documentation so you know exactly what you’re dealing with before any work begins.
Our Duct Repair & Sealing Process - Step by Step
- 1
Schedule and confirm. When you call (855) 305-5564, a live person answers and finds a window that works for your schedule. We’ll confirm the appointment by phone the day before, and our technician calls when they’re en route. We’ll be there when we say.
- 2
Camera inspection and assessment. Before touching a tool, we run a borescope camera through your ductwork to document the condition. You see what we see - rust, gaps, crushed sections, or animal damage. This inspection is free with any service call, and the footage becomes the baseline for measuring our results.
- 3
Upfront pricing, no surprises. Based on what we find, we present a clear, itemized price before work begins. If the scope changes during the job, we discuss it with you first. The price we quote is the price on the invoice - no bait coupons, no add-ons at the door.
- 4
Professional repair with proper materials. Our technicians use mastic sealant, metal-backed tape, and mechanical fasteners - never shortcuts like plain duct tape or spray foam. For flex duct, we use proper supports every four feet to prevent sagging. For metal, we fabricate replacement sections on site.
- 5
Post-repair verification and cleanup. We run the camera again to confirm the repair, test airflow at each vent, and clean up thoroughly. You receive a written report with before-and-after images and our 90-Day Done Right Promise. If anything isn’t right, we make it right with no paperwork and no arguing.
How Much Does Duct Repair & Sealing Cost in Atlanta?
A typical duct sealing job in Atlanta runs $350 to $650 for a single system in a home under 3,000 square feet. Flex duct repair for a single damaged section usually falls between $250 and $450, while metal duct repair involving custom fabrication can range from $400 to $850 depending on accessibility and the extent of corrosion. Full duct insulation for an attic trunk line typically costs $500 to $900. These are the ranges we see across our service area, from Brookhaven to Fair Oaks to Austell.
Several factors move the price within these ranges. Attic access matters - a tight crawl with blown-in insulation takes longer than a walk-up attic with plywood flooring. The extent of damage affects material and labor; a single disconnected joint is a quick fix, while a rusted-out trunk line requires more time. And the age of your system can matter too - very old galvanized duct may be too far gone to repair cost-effectively, and we’ll tell you honestly if replacement makes more sense than sealing.
To avoid overpaying, get a written estimate that specifies exactly what’s included, and be wary of phone quotes that sound too low to cover proper materials and labor. Our estimates are free, detailed, and come with no obligation. We also offer a Free Second Opinion on Any Written Estimate you’ve received from another contractor, and $50 Off Any Repair Over $250 for new customers. Call (855) 305-5564 for your exact quote.
