Why Titan Air Duct Cleaning Greater Dayton Is Urbana’s Preferred Duct Repair & Sealing Company
We’ve earned Urbana’s trust through two decades of showing up and doing the work ourselves. Thomas Hernandez — our owner and lead technician — personally handles every duct repair and sealing job, so the person you talk to on the phone is the same one crawling through your attic crawl space with a mastic brush. That matters in Urbana, where legacy ductwork demands problem-solving you can’t delegate to a trainee with a checklist.
Our 113 verified reviews averaging 4.7 stars include repeat customers from Champaign County who’ve watched us solve problems other crews missed. One Urbana homeowner on South Main Street had two previous companies apply foil tape to a leaking return plenum; the tape failed within months because nobody addressed the irregular seam geometry left by a 1940s gravity-furnace conversion.
We carry professional-grade equipment from Rotobrush and Nikro on every truck, and we stock mastic sealant, fiberglass mesh tape, and bonding agents formulated for bare galvanized metal — the exact combination Urbana’s older ductwork requires. Our response time to Urbana averages under an hour for scheduled appointments, and we route through Springfield or New Carlisle depending on traffic to keep that commitment.
Our Duct Repair & Sealing Services in Urbana
Duct Sealing
Sealing in Urbana means confronting ductwork that was never designed for forced-air pressure. Many homes near the downtown core and along East Lawn Avenue still run on systems converted from gravity furnaces in the 1960s and 70s, with oversized plenums and hand-formed seams that standard foil tape can’t bridge. We test your system with a pressure gauge, identify every leak point, then select the appropriate sealant — mastic for irregular joints, high-temperature tape for smooth metal-to-metal connections, and expanding foam where ducts penetrate framing. A typical duct sealing job in Urbana runs $280–$450 for a single system with accessible ductwork.
Flex Duct Repair
Flex duct installed during 1990s additions and renovations is now reaching the end of its service life in Urbana homes. The spiral-wire helix corrodes in humid attics, and the inner liner collects debris that standard cleaning can’t extract — especially after harvest season, when Champaign County’s airborne particulate loads are at their peak. We remove damaged sections, install new insulated flex with proper support straps to prevent sagging, and seal all connections with mastic rather than zip ties alone. Flex duct repair in Urbana typically costs $180–$320 per section, including materials.
Metal Duct Repair
Urbana’s legacy galvanized steel ductwork — the bare-metal plenums and branch lines from converted octopus furnaces — rusts at seams, separates at joints, and rattles against framing when the blower cycles. We don’t patch and pray. We cut out corroded sections, fabricate replacement pieces from matching gauge steel, and secure them with S-locks and drive cleats before sealing. For a 1952 bungalow on North Walnut Street, the return-air plenum was originally part of a coal gravity furnace — three feet wide, with riveted seams that had opened over time. We brushed and vacuumed the interior, then applied mastic sealant with fiberglass mesh over every joint, stopping the dust infiltration from the attic crawl space. Metal duct repair in Urbana ranges from $350 for spot welding and sealing to $650 for section replacement.
Mastic Sealant Application
Mastic is our go-to for Urbana’s irregular, legacy joints — the stuff foil tape was never designed to handle. We apply it with a brush or trowel over fiberglass mesh tape, building a flexible, permanent seal that moves with thermal expansion. On bare galvanized interiors, we first prime with a bonding agent to prevent shearing. This isn’t a quick squirt from a caulk gun; it’s a craft process that takes time and access. Mastic sealing alone, for a typical Urbana system with 8–12 major joints, runs $220–$380.
Duct Insulation
Uninsulated or degraded duct insulation in Urbana’s unconditioned attics and crawl spaces wastes energy and creates condensation points where mold colonizes. We wrap supply ducts with formaldehyde-free fiberglass insulation, sealed with vapor-barrier jacketing, paying special attention to the temperature differentials that west-central Ohio’s humid continental climate creates. Duct insulation in Urbana typically costs $2.50–$4.00 per linear foot, with most residential systems running $300–$550 total.

We don’t upsell for the sake of it; we match the right product to the specific conditions your ductwork faces in Champaign County.
Common Duct Repair & Sealing Problems We See in Urbana Homes
- Oversized plenums from converted gravity furnaces. These three-foot-wide rectangular boxes have hand-riveted or spot-welded seams that open under forced-air pressure. Standard foil tape spans maybe an inch; these gaps run three inches in places. We bridge them with mastic and mesh, applied in layers.
- Bare galvanized interiors that reject poorly chosen sealants. Without a bonding agent, mastic skins over but never adheres, shearing off in sheets within a year. We see this failure mode in homes near Urbana’s north side where previous owners or handymen tried quick fixes.
- Harvest-season chaff loading in flex duct. That fine tan dust — corn chaff, soybean hull fragments — embeds in flex-duct liner pleats during September and October. You can’t seal over it; we extract it first with Rotobrush agitation and Nikro vacuum, then seal the now-clean surface.
- Rattling metal against framing during blower cycle. Common in homes along East Court Street and similar vintage neighborhoods. The duct isn’t just noisy — it’s moving, which means joints are working loose and leaks are worsening. We secure with strap iron and isolate with rubber padding before sealing.

| Service | Typical Range |

What moves you within these ranges? Accessibility is the big one — crawl spaces under 30 inches add time; so does working around knob-and-tube wiring we sometimes encounter in pre-1960 Urbana homes. The extent of harvest-season debris loading affects prep time. And the condition of your existing ductwork determines whether we’re sealing, repairing, or replacing sections. We quote upfront after inspection, not after starting work. Call (866) 834-6947 for your free estimate — we’ll look at your specific system and give you a firm number.

FAQs — Duct Repair & Sealing in Urbana
Mastic sealant bridges gaps up to several inches wide and conforms to irregular surfaces, while foil tape fails when stretched over the oversized, hand-formed seams common in Urbana’s converted gravity-furnace plenums. We apply mastic with fiberglass mesh tape for structural reinforcement, creating a flexible seal that withstands thermal cycling. For a free inspection of your duct seams, call us at (866) 834-6947.
Rattling usually indicates both a support problem and a developing leak: the duct is moving, which works joints loose and enlarges gaps. We secure the duct with proper strapping and isolate it from framing, then seal all joints to prevent the leak from worsening. This is a common call from Urbana’s 1920s–1960s neighborhoods. Call (866) 834-6947 and we’ll quiet it down.
The fine particulate from corn and soybean operations — visible as tan dust on filters each fall — embeds in duct liner and collects at joints, preventing sealants from adhering to clean metal. We clean first, seal second. This seasonal loading pattern is unique to farm-county towns like Urbana and doesn’t occur at these concentrations in purely urban markets. For pre-harvest duct inspection and sealing, call (866) 834-6947.
Yes, if the flex duct is structurally sound — no tears, crushed sections, or corroded wire helix. We extract embedded debris with Rotobrush and Nikro equipment, then seal connections with mastic and proper support to prevent future sagging. If the liner is degraded, replacement is the better investment. We’ll tell you which after inspection; call (866) 834-6947 for a free look.
Properly applied mastic with bonding agent on primed galvanized metal lasts 15–20 years in west-central Ohio’s conditions, outliving foil tape by a factor of three. The key is surface preparation — bare galvanized that wasn’t primed, or mastic applied over dust, will fail in 2–3 years. We do it once and do it right. For mastic sealing that holds up through Urbana’s humid summers, call (866) 834-6947.
