Our Duct Repair & Sealing Services in Bexley
Duct Sealing
Air leaks in Bexley’s older duct systems waste 20-30% of heated and cooled air before it reaches your rooms. We seal supply and return ducts with professional-grade mastic and metal-backed tape, then pressure-test the system to verify results. In Bexley’s humid continental climate, proper sealing also keeps muggy summer air from infiltrating through gaps and condensing inside cool ductwork.
Metal Duct Repair
Galvanized steel ducts from the 1960s and 70s corrode, separate at seams, and rattle against joists in Bexley’s basements. We repair or replace damaged sections, reinforce sagging runs, and secure hangers so the system runs quiet. Many Bexley homes have metal ducts routed through former coal-chute cavities - spaces never designed for HVAC - where we find rust, debris accumulation, and disconnected joints hidden behind finished walls.
Flex Duct Repair
Flexible duct installed during basement renovations often gets kinked, crushed, or pulled loose from registers. We replace damaged flex runs with properly sized material, support it to prevent future sagging, and seal every connection. Finished basements in neighborhoods like Broadleigh are especially prone to this - homeowners add a rec room and never realize the contractor pinched a duct behind the new drywall.
Duct Insulation
Uninsulated or degraded duct insulation in Bexley’s attics and crawlspaces loses energy and creates condensation problems. We install fresh insulation on repaired ducts, sized for Ohio’s temperature swings. This matters more in Bexley than in newer construction because retrofit ductwork often runs through unconditioned spaces that weren’t part of the original heating design.
Mastic Sealant
For Bexley’s old steel ducts with failing tape and gaps at joints, we brush on water-based mastic sealant that cures to a permanent, flexible bond. Unlike duct tape - which peels within months in Central Ohio’s humidity - mastic lasts the life of the system. We apply it to every seam, collar, and connection we can access, then show you the before-and-after with our camera inspection.
Air Leak Repair
Return-air leaks pull attic air full of pollen and mold spores directly into your system. In Bexley, where the mature tree canopy drives some of Franklin County’s heaviest spring pollen loads, this recirculates allergens you can’t see. We find and repair these leaks, seal filter racks, and verify that your system breathes clean indoor air - not attic air.

For Bexley homeowners, this means we don’t order parts from a catalog and make you wait. Our trucks stock mastic sealant, metal repair sleeves, flex duct in common diameters, and insulation for the range of systems we encounter in 1920s-1950s housing. When we find a problem, we fix it that day. No return trip, no “we’ll call you when it comes in.”
Common Duct Repair & Sealing Problems We See in Bexley Homes
- DIY duct tape failing in humid summers. Homeowners in Bexley try sealing visible gaps with hardware-store duct tape, but Central Ohio’s muggy July and August air breaks down the adhesive within a season. The tape peels, the leak returns, and conditioned air escapes into attics or crawlspaces. We remove the failed tape and apply mastic that won’t budge.
- Unsealed return-air grilles pulling in attic contaminants. Bexley’s dense tree canopy produces pollen loads that clog return grilles and migrate into ductwork. When returns leak in the attic, the system recirculates those allergens plus mold spores from hot, humid roof spaces. We seal the filter rack and test for negative pressure.
- Kinked flex duct from basement renovations. Finished basements in Bexley’s large homes often hide flex runs that got bent during framing or drywall installation. The result is weak airflow, longer run times, and a whistling or flapping noise every time the blower starts. We reroute and support the duct properly.
- Disconnected ducts in concealed coal-chute chases. This is the one that surprises homeowners. During 1960s boiler-to-forced-air conversions, contractors often ran supply ducts through original coal-chute cavities or plaster-wall chases - spaces with sharp turns, debris traps, and no access panel. We’ve found sections completely blocked with 50 years of accumulation, or joints that separated where no one could see. Our flexible Rotobrush systems and camera inspection reach these dead ends that standard equipment misses.

FAQs - Duct Repair & Sealing in Bexley
Bexley’s homes were built between the 1920s and 1950s, then retrofitted with forced-air duct systems in the 1960s-70s - often poorly sized and routed through spaces never designed for HVAC. These systems have accumulated debris for 50-60 years inside ducts that are smaller, more convoluted, and less accessible than modern construction. Sealing and repairing them properly requires equipment flexible enough for tight chases and technicians who know what they’re looking at. Call (844) 685-6342 and we’ll show you exactly what your system looks like inside.
Yes. We use flexible camera systems and rotary brushes that navigate through existing registers and small access openings without cutting into finished surfaces. In a 1930s Tudor on Drexel Avenue, we sealed supply ducts that had been routed through a former coal chute during a 1960s conversion. The homeowner had noticed uneven airflow and increased dust; we used mastic sealant and metal repair to fix air leaks and a Rotobrush system to extract decades of debris from the tight chase. When wall access is unavoidable, we discuss it with you first and minimize intrusion.
We use water-based mastic sealant, brushed on thick at every joint, seam, and collar. Unlike foil tape or hardware-store duct tape - which fails within months in Ohio’s humidity - mastic cures to a permanent, flexible bond that lasts the life of the duct. For Bexley’s old galvanized steel with corroded edges, we also use mesh-reinforced mastic on larger gaps and metal repair sleeves where the duct itself has deteriorated.
We pressurize each zone independently and measure airflow at every register with a digital manometer and flow hood. This tells us whether the problem is a central trunk leak, a disconnected branch, or a blocked run. Bexley’s multi-zone systems - often added piecemeal during renovations - can have dampers that are stuck or manually closed, creating symptoms that look like leaks but aren’t. Our testing separates real leaks from control issues so we fix the right thing.
Sealing leaks in the return side of your system will reduce the pollen and mold spores being pulled from attics and wall cavities. However, sealing alone won’t stop pollen that enters through normal register airflow. For homeowners who struggle with Bexley’s exceptional tree canopy - one of the densest in Franklin County - we often combine duct sealing with upgraded filtration and a thorough cleaning of the return-air pathway. The result is less recirculated outdoor allergen and a system that breathes cleaner air. Call (844) 685-6342 for an exact quote - estimates are free.
