Fast, Reliable Duct Repair & Sealing Across Worthington
Duct repair and sealing in Worthington, OH typically costs between $280 and $850 depending on the scope, and most jobs are completed in a single visit. If you’re living in a 1950s colonial off High Street or a Cape Cod near Wilson Hill Road, your duct system is likely working harder than it was ever designed to — and leaking conditioned air into your crawlspace, attic, or walls.
We’re Legacy Air Duct Cleaning Columbus, and our Duct Repair & Sealing team knows Worthington’s housing stock inside and out. Paul Torres, our owner and lead technician, has spent 8 years sealing and repairing ductwork in the exact neighborhoods you’re driving through — from the historic village core to the acreage properties along the northern edge. We carry Rotobrush and Nikro equipment plus the mastic, flex duct, and metal fittings to fix most problems without a return trip. Call (844) 945-2561 for a free estimate.
Why Legacy Air Duct Cleaning Columbus Is Worthington’s Preferred Duct Repair & Sealing Company
We’ve earned 935 verified customer reviews averaging 4.7 stars — and a significant share of those come from repeat Worthington homeowners who’ve watched us seal panned-joist returns in their colonials and insulate bare metal duct in their Cape Cods. They don’t call us back because we’re the cheapest option. They call because Paul Torres shows up personally as lead technician, diagnoses the actual problem, and fixes it with equipment that matches the job.
Our response time to Worthington is typically same-day or next-day, since we’re based in Columbus and regularly working the 43085 zip code and the High Street corridor. We know which Worthington homes have crawlspace air handlers prone to moisture damage, which neighborhoods built during the 1960s subdivision boom have the worst panned-joist return issues, and how to access retrofitted ductwork in the historic village core where conventional chases don’t exist.
Nearly 1,000 customers reviewed us. That volume matters — it means we’ve seen the specific duct failures that repeat across Worthington’s aging housing stock, and we’ve developed repair methods that last.
Our Duct Repair & Sealing Services in Worthington
Mastic Sealant Application
Mastic sealant is our primary weapon against the leaky ductwork we find in Worthington’s 1950s–1970s homes. On a colonial off Selby Boulevard, we sealed a panned-joist return that was sucking in fiberglass insulation and crawlspace moisture. We applied mastic sealant to the joints, replaced a section of flex duct at the air handler, and installed a Honeywell media filter to trap the debris we couldn’t clean out. The homeowner called it the first time the upstairs bedrooms felt balanced in winter.
Standard duct tape fails in 2–3 years. Mastic, properly applied to clean metal, lasts 15–20. We use Abatement Technologies mastic products rated for residential HVAC temperatures, and we prep the surface first — critical on Worthington’s original panned-joist returns, where decades of oily dust and moisture contamination can cause premature sealant failure if you skip the degreasing step.
Air Leak Repair
Air leaks in Worthington ductwork fall into two categories: the obvious ones you can feel blowing from a register that isn’t connected, and the hidden ones pulling crawlspace air through gaps in panned joists or separated flex duct connections. We pressure-test the system before and after repair to measure actual improvement. Most Worthington homes we test leak 25–40% of their conditioned air before we start. After sealing, we typically see that drop to 8–12%.
Leaks at the air handler plenum are especially common in Worthington’s retrofitted systems, where a furnace was added to a home that originally had radiator heat. The transition fittings are often custom-fabricated and poorly sealed — a weak point we reinforce with mastic and mechanical fasteners.
Flex Duct Repair & Replacement
Flex duct in Worthington crawlspaces takes a beating. The humid continental climate here delivers wide seasonal temperature swings, and Worthington’s position near the Olentangy River corridor adds ambient moisture that degrades the outer vapor barrier over time. We’ve replaced crushed flex duct in crawlspaces where raccoons or rodents have used the soft material as nesting material — more common on Worthington’s acreage properties with detached workshops and outbuildings where access is limited and inspection is infrequent.
When we replace flex duct, we use insulated, vapor-barrier-protected product rated for below-grade installation, and we support it properly every 4–5 feet. Sagging flex duct is crushed flex duct waiting to happen.
Metal Duct Repair
Original sheet-metal ductwork in Worthington’s post-WWII homes is now 50–70 years old. The longitudinal seams on rectangular trunk lines separate. Support hangers corrode and let sections sag. We repair with proper sheet-metal screws, seal with mastic, and add support where the original hangers have failed. For detached workshops and outbuildings common on Worthington’s larger lots, we see large metal duct sections pull apart at the seams due to temperature cycling and lack of support — a different repair profile than interior basement trunk lines.
Duct Insulation
Bare metal duct in unconditioned spaces — attics, crawlspaces, garages — loses significant energy. In Worthington’s Cape Cods off Wilson Hill Road, we’ve found bare metal supply runs in kneewall attics that drop air temperature 8–10 degrees before it reaches the bedroom. We wrap with formaldehyde-free fiberglass insulation jacketed with reinforced vapor barrier, sealed at all seams. The improvement in comfort and efficiency is immediate and measurable.

Trusted Brands We Service in Worthington
We stock parts and materials from Honeywell, Aprilaire, and Abatement Technologies — brands we trust because they hold up in the conditions we actually encounter. For Worthington homeowners, that means faster turnaround: when we diagnose a failed component during your service call, we don’t order it and make you wait. We carry Honeywell media filters, Aprilaire humidifier pads, and Abatement Technologies mastic and sealants on every truck. Paul Torres selects these brands based on 8 years of field performance in Central Ohio’s humidity and temperature swings, not on distributor incentives.
Common Duct Repair & Sealing Problems We See in Worthington Homes
- Panned floor joist returns pulling in crawlspace air. Worthington’s 1950s–60s colonials commonly used this construction shortcut, and it’s a defect rarely found in newer Columbus suburbs. The joist cavities become return-air pathways, sucking in dust, fiberglass, and moisture from below the home. We seal these with mastic after thorough surface prep.
- Collapsed flex duct from rodent activity in acreage crawlspaces. Worthington’s larger lots with detached outbuildings often go longer between inspections. Raccoons and rodents find the soft flex duct irresistible for nesting material. We replace with properly supported, protected duct and recommend exclusion measures.
- Separated metal seams in detached workshop ductwork. Temperature cycling between unheated outbuildings and conditioned air causes expansion and contraction that pulls apart unsupported metal sections. We re-seam, support, and insulate to prevent recurrence.
- Mastic sealant failure on contaminated original metal. Decades of oily dust and moisture on Worthington’s original panned-joist returns will cause new mastic to peel if the surface isn’t properly degreased and primed. We don’t skip this step, which is why our seals last.

FAQs — Duct Repair & Sealing in Worthington
Yes, we see panned floor joists regularly in Worthington’s 1950s–60s colonials, and we can seal them properly. The key is surface preparation — decades of oily dust and moisture contamination will cause new mastic to fail if you don’t degrease and prime first. We use Abatement Technologies mastic rated for this application and verify the seal with pressure testing. Call (844) 945-2561 for a free inspection — we’ll show you exactly what condition your returns are in.
We repair and replace ductwork in detached workshops and outbuildings throughout Worthington’s acreage properties. Crushed flex duct from rodent activity or impact damage is common in these structures, and we carry the insulated, protected replacement product and proper support hardware to fix it in one trip. Paul Torres will assess whether the damage is localized or if the entire run needs replacement. Call (844) 945-2561 — estimates are free.
Proper duct sealing significantly reduces pollen infiltration by eliminating the suction points where unfiltered outside air enters your system. Worthington’s mature tree canopy — a deliberate part of the city’s character since 1803 — creates some of the heaviest seasonal pollen loads in the Columbus metro. Sealing panned-joist returns, plenum gaps, and separated duct connections prevents your HVAC from pulling that pollen-laden air from crawlspaces and wall cavities. For additional protection, we can install a Honeywell media filter at the air handler. Call (844) 945-2561 to discuss your specific situation.
Yes, we insulate bare metal duct in Worthington’s Cape Cods and other homes with unconditioned attic or crawlspace runs. The kneewall attics common in Cape Cods off Wilson Hill Road often contain bare metal supply lines that lose 8–10 degrees of temperature before air reaches your bedroom. We wrap with formaldehyde-free fiberglass insulation with reinforced vapor barrier, sealed at all seams. The comfort improvement is immediate. Call (844) 945-2561 for an estimate.
We specialize in indoor air quality and duct systems — air duct cleaning, dryer vent cleaning, HVAC cleaning, duct repair and sealing, and air quality sanitizing. We don’t service garage door springs or openers. For heavy-duty garage door spring repair in Worthington, you’ll want a dedicated garage door contractor with the proper torsion spring tools and safety training. If your detached shop has ductwork or ventilation needs, we’re the right call for that. Call (844) 945-2561 for any duct, vent, or indoor air quality service.
