Fast, Reliable Duct Repair & Sealing Across Upper Arlington
Duct repair and sealing in Upper Arlington, OH typically costs $280–$750 for most residential jobs, with same-day assessments available throughout the 43212 area. We’re usually on Tremont Road, Cambridge Boulevard, or one of the side streets off Lane Avenue within 25 minutes of your call.

Upper Arlington’s homes aren’t like the rest of Columbus. The gravity-furnace conversions that heated these neighborhoods from the 1930s through the 1960s left behind ductwork systems that most generalist HVAC crews simply aren’t equipped to handle properly. Our Duct Repair & Sealing team knows these streets and these houses. Paul Torres shows up personally as lead technician on your job, bringing 8 years of focused air duct specialization and the professional-grade Rotobrush and Nikro systems needed for oversized plenum trunks that standard equipment can’t touch. When you’re dealing with 60-year-old galvanized steel, unsealed joints, and the humidity problems that come with living near the Olentangy floodplain, you need someone who’s done this exact work in Upper Arlington before — not a franchise crew learning your house on the fly.

Why Legacy Air Duct Cleaning Columbus Is Upper Arlington’s Preferred Duct Repair & Sealing Company
We’ve built our reputation one Upper Arlington home at a time. Nearly 1,000 customers have reviewed our work at a 4.7-star rating, and many of those reviews come from repeat visits to the same Tudor Revival and Colonial neighborhoods where word travels fast between neighbors on streets like Barrington Road and Ridgeview Middle School’s surrounding blocks.
Paul Torres doesn’t delegate your job to a rotating crew. He shows up personally as lead technician, which means the most experienced person in our company is the one crawling through your crawl space, inspecting your plenum trunks, and applying mastic sealant to joints that haven’t been touched since the Eisenhower administration. That’s a level of accountability you won’t find with generalist handymen or franchise operations that treat duct repair as an add-on service.
Our response time to Upper Arlington averages under 30 minutes during business hours because we’re based in Columbus and know these roads. We don’t need GPS to find the split-levels off Zollinger Road or the Cape Cods near Thompson Park. That local familiarity translates to faster diagnostics and more accurate estimates — we’re not guessing at what we’ll find behind your walls.
Eight years doing one thing well means we’ve encountered virtually every duct configuration Upper Arlington’s housing stock can produce. The asbestos-wrapped supply plenums in pre-1960s homes, the irregularly routed galvanized lines from gravity conversions, the humidity-compromised flex duct in additions — we’ve sealed and repaired them all.
Our Duct Repair & Sealing Services in Upper Arlington
Mastic Sealant Application
Mastic sealant is our go-to solution for Upper Arlington’s unsealed metal joints, and it’s particularly critical for gravity-conversion systems where decades of thermal expansion have opened gaps at trunk-line connections. We apply fiberglass-reinforced mastic by hand to every accessible joint, creating a permanent flexible seal that outlasts foil tape by decades. In Upper Arlington’s older homes, this process takes longer than standard suburban jobs because we’re working with 16–20 inch wide plenum trunks that require thorough coverage across oversized surface areas. The mastic cures to a hard, durable finish that withstands the humidity cycling these river-adjacent homes experience through Ohio’s muggy summers.

Metal Duct Repair
The galvanized steel trunk lines in Upper Arlington’s 1930s–1960s housing stock weren’t designed for forced-air systems, and after 60–80 years they’re showing it. We repair separated seams, corroded sections, and damaged take-off collars using professional-grade sheet metal techniques and proper mechanical fastening — not duct tape, not temporary patches. When we encounter the oversized rectangular trunks common along Tremont Road and Cambridge Boulevard, we fabricate custom transition pieces rather than forcing incompatible fittings. These repairs restore structural integrity to systems that standard residential cleaning equipment often can’t even access properly.

Flex Duct Repair & Replacement
Many Upper Arlington homeowners added flex duct runs during basement finishing projects or kitchen renovations, and these newer sections often fail first — crushed by storage items, chewed by rodents, or degraded by the temperature fluctuations in unconditioned crawl spaces. We replace damaged flex with properly sized, insulated runs that match your system’s static pressure requirements. Unlike the original metal trunks, flex duct demands precise length and support calculations; too long or unsupported, and you’ll get sagging sections that trap debris and reduce airflow to second-floor bedrooms.

Duct Insulation
Upper Arlington’s humid summers and cold winters punish uninsulated ductwork in attics and crawl spaces. We install formaldehyde-free fiberglass duct wrap or closed-cell foam insulation depending on your system’s configuration and accessibility, with particular attention to supply plenums that pass through unconditioned spaces. Proper insulation doesn’t just save energy — in this climate, it prevents the condensation that feeds mold growth inside your ductwork, especially critical for homes near the Olentangy where baseline humidity already runs higher than Columbus’s eastern suburbs.

Trusted Brands We Service in Upper Arlington
We work with the equipment and components that professional IAQ contractors trust: Rotobrush and Nikro mechanical agitation systems for thorough cleaning access, Honeywell and Aprilaire media filters and whole-house humidifier components, plus Abatement Technologies HEPA filtration and Guardsman protective products. For Upper Arlington’s vintage systems, we stock a range of sheet metal fittings, mastic compounds, and insulation materials sized for larger-diameter trunk lines — parts that many standard HVAC suppliers don’t keep on hand because they’re outside modern residential norms. That inventory means faster turnaround on your repair, fewer return visits, and a system that actually performs after we’re done.
Common Duct Repair & Sealing Problems We See in Upper Arlington Homes
- Oversized plenum trunks from gravity-furnace conversions — These 16–20 inch wide rectangular channels are too large for standard flex-line whip tools, leaving decades of compacted debris and unsealed leaks untouched by conventional cleaning crews. We bring larger-diameter Rotobrush equipment and longer cleaning windows to address what others simply can’t reach.
- Asbestos-wrapped supply plenums in pre-1960s homes — The Cape Cods and early Tudors near Thompson Park often feature original asbestos insulation on ductwork that complicates any sealing or repair work. We identify these materials before work begins and coordinate with certified abatement specialists when disturbance is unavoidable — never cutting corners on safety protocols.
- Humidity-driven mold in river-adjacent microclimates — Upper Arlington’s position next to the Olentangy floodplain, combined with Central Ohio’s muggy summers, creates indoor humidity loads that exceed what poorly sealed ductwork can handle. Return-air intakes under the city’s dense tree canopy pull in leaf mold and pollen that colonize damp duct interiors, spreading spores through every room.
- Unsealed joints at gravity-conversion transitions — The original furnace removals left irregular connection points between old trunk lines and new forced-air equipment, often sealed with failing foil tape or nothing at all. These leaks pressurize crawl spaces and wall cavities instead of delivering conditioned air to your rooms, wasting energy and creating pressure differentials that pull in unfiltered outside air.
Pricing for Duct Repair & Sealing in Upper Arlington, OH
Here’s what duct repair and sealing actually costs in Upper Arlington’s market:
| Service | Typical Range |
|---|---|
| Mastic sealant application (standard system) | $280–$450 |
| Metal duct repair (per section/replacement) | $180–$340 |
| Flex duct repair or replacement (per run) | $220–$380 |
| Duct insulation (per linear foot) | $8–$14 |
| Full system assessment with sealing plan | $150–$200 (credited toward work) |
Several factors push Upper Arlington jobs toward the higher end of these ranges. The oversized gravity-conversion trunk lines require more mastic, more labor time, and specialized equipment access that simpler suburban systems don’t demand. Asbestos-wrapped components add abatement coordination costs. Homes with multiple additions or finished basements often have mixed duct materials that each need different repair approaches.
We don’t quote over the phone for these jobs — the variability in Upper Arlington’s housing stock demands a visual inspection. Our assessment fee runs $150–$200, but we credit that entire amount toward any work you approve. Call (844) 945-2561 to schedule; estimates are free once we’re on site and evaluating your specific system.

FAQs — Duct Repair & Sealing in Upper Arlington
Your wide rectangular trunks are almost certainly remnants of a gravity (octopus) furnace conversion completed in the 1950s or 1960s, when your home switched from coal or oil gravity heat to forced air without replacing the original ductwork. These 16–20 inch plenum trunks were sized for natural convection, not blower-driven airflow, and they’re now 60–80 years old — far older than ductwork in Dublin, Hilliard, or Westerville. Call (844) 945-2561 and we’ll assess whether sealing and repair can improve their performance or if strategic replacement makes more sense for your system.
Yes — spring and summer storms in Central Ohio drive humidity spikes that exploit every unsealed joint in your ductwork, and Upper Arlington’s river-adjacent location already puts you above average for baseline moisture. Sealing before May prevents the condensation and mold colonization that peak humidity triggers, especially in return-air paths that pull from your crawl space or attic. We typically book these pre-season sealing jobs in March and April; call (844) 945-2561 to get on the schedule before the humidity arrives.
We can work on systems with asbestos-wrapped components, but we do not disturb asbestos insulation ourselves — that’s a certified abatement specialist’s job, and it’s required by Ohio EPA regulations. Our process involves identifying asbestos materials during assessment, coordinating with licensed abatement contractors for safe removal when necessary, then completing your duct sealing and repair on clean, accessible metal. Many Upper Arlington pre-1960s homes require this two-step approach; we’ll explain exactly what your system needs during our free on-site estimate.
Upper Arlington’s mature oak and maple canopy generates some of Franklin County’s highest spring pollen and leaf-mold spore counts, which your return-air intakes pull directly into your ductwork if the filter seals and plenum joints aren’t tight. Those organic loads then feed mold colonies in any section where humidity condensation occurs — a combination we see frequently in homes east of Riverside Drive near the river corridor. Proper sealing eliminates the moisture access points; upgraded filtration captures the spores before they enter. Call (844) 945-2561 and we’ll evaluate both your sealing and your filtration setup.
Sealing is often worth it even on 70-year-old galvanized systems if the metal itself is structurally sound — no significant corrosion, no separated seams beyond repair, no collapsed sections. In Upper Arlington specifically, we’ve found that gravity-conversion trunk lines from the 1940s–1950s are frequently thicker-gauge steel than modern ductwork, and they can perform well for decades more with proper mastic sealing and strategic repairs. The key question is whether your specific system’s condition supports sealing or if replacement of critical sections makes more sense; our assessment gives you that answer with photos and straight talk, not pressure. Call (844) 945-2561 for an honest evaluation.
