What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, cracks, and separations in your supply and return ductwork that allow conditioned air to escape into attics, crawl spaces, or wall cavities. In Columbus, we regularly find homes in neighborhoods like Clintonville and Bexley losing 20–30% of heated or cooled air through poorly sealed joints — especially in ranch-style homes with extensive basement or crawl space duct runs. Michael applies mastic sealant and professional-grade metal-backed tape at every connection point, then pressure-tests the system to confirm the seal holds under operating conditions.
Flex Duct Repair
Flex duct — the insulated, flexible tubing common in Columbus home additions and attic installations — crushes, tears, or disconnects over time, particularly where it passes through hot summer attics or unconditioned crawl spaces. We’ve replaced crushed flex duct in Grandview Heights attics where improper support caused complete airflow blockage to second-floor bedrooms. Summit carries replacement flex duct in standard diameters and installs proper support straps and protective sleeves to prevent the same failure from recurring.
Metal Duct Repair
Galvanized steel ductwork found in older Columbus homes — particularly in Victorian Village, German Village, and the Near East Side — can rust through at seams, separate at joints, or suffer damage from prior renovations or pest intrusion. Michael fabricates custom patch panels and replacement sections on-site, sealing with mastic rather than relying solely on tape that degrades. We’ve restored original metal duct systems in 1920s-era homes where preserving the existing infrastructure was preferable to full replacement.
Duct Insulation
Uninsulated or degraded duct insulation in unconditioned spaces wastes energy and creates condensation problems during Columbus’s humid summers and freezing winters. In neighborhoods like Upper Arlington and Worthington, we encounter attic ductwork with original fiberglass insulation that has compressed to half its R-value or absorbed moisture and mold. Summit removes compromised insulation and installs new foil-faced fiberglass or closed-cell foam insulation sized to the specific duct diameter, sealed at all seams to maintain thermal performance.
Mastic Sealant Application
Mastic is a thick, fiber-reinforced compound that remains flexible after curing, making it superior to tape for sealing duct joints and seams in Columbus’s climate of expansion-contraction cycles. Unlike duct tape — which degrades and fails within months — proper mastic application lasts the life of the duct system. Michael brushes mastic into every longitudinal seam, transverse joint, and register boot connection, then allows full cure time before returning the system to service.
Air Leak Repair
Air leaks in ductwork often manifest as whistling sounds, dust streaks near registers, or rooms that never reach the thermostat setpoint. In Westerville and Dublin subdivisions with slab-on-grade construction, we’ve traced leaks to separated duct boots where the duct meets the floor register. Summit’s repair process includes smoke-pencil or blower-door-assisted leak detection to locate every escape point, then targeted sealing or replacement of the failed component.

Brands We Service for Duct Repair & Sealing
We’ve serviced and repaired duct systems connected to Honeywell air cleaners and whole-home humidifiers across hundreds of Columbus homes, integrating duct sealing work with existing IAQ component locations to avoid disrupting calibrated airflow paths. Our familiarity with Honeywell’s pressure-drop specifications means we don’t compromise the performance of your filtration system when modifying nearby ductwork.
We also regularly encounter Aprilaire dehumidifiers and ventilation controllers in Powell and Dublin homes with tight building envelopes, where duct sealing is critical to maintaining the precise airflow rates these systems require. Whether your home has Honeywell, Aprilaire, or any other make of HVAC or IAQ equipment, we can assess how duct condition affects overall system performance and repair accordingly.
Signs You Need Duct Repair & Sealing Right Now
- Uneven temperatures room-to-room. If your bedroom in Blacklick Estates stays ten degrees colder than your kitchen in January, or your upstairs in Reynoldsburg won’t cool in July, restricted or leaking ductwork is the likely cause. This isn’t just discomfort — your HVAC system runs longer and harder, accelerating wear on the compressor and blower motor.
- Spiking energy bills without usage changes. Columbus homeowners who see winter gas bills jump 25–40% year-over-year often discover significant duct leakage in crawl spaces or attics. You’re paying to heat or cool spaces you don’t occupy, and the waste compounds with every rate increase from Columbia Gas or AEP Ohio.
- Excessive dust despite regular filter changes. When return ducts pull air from dusty attics or crawl spaces through gaps in the duct wall, that debris bypasses your filter entirely and distributes through every register. We’ve found this particularly in 1970s–1990s ranch homes in Grove City and Hilliard with original ductwork.
- Whistling, rattling, or whooshing sounds. High-velocity airflow through gaps in duct seams creates distinctive noise signatures that change with system operation. A whistle near the air handler often indicates a large return-side leak; rattling in walls suggests a disconnected flex duct flapping in the cavity.
- Visible duct damage or disconnected runs. If you can see crushed, torn, or separated ductwork in your basement, crawl space, or attic, the condition is almost certainly worse in areas you can’t access. Columbus’s freeze-thaw cycles and humid summers accelerate deterioration of unsupported flex duct and corrode unprotected metal.
Our Duct Repair & Sealing Process — Step by Step
- 1
System inspection and airflow assessment. Michael starts every job with a visual inspection of accessible ductwork and a static pressure test using a digital manometer. This establishes baseline performance and identifies whether problems originate on the supply side, return side, or both — common in older Columbus homes with modified floor plans.
- 2
Leak detection and damage documentation. We use a smoke pencil or theatrical fog generator to trace air movement at seams, joints, and register boots, then photograph all damage for your records. In homes with finished basements or sealed attics, we employ borescope cameras to inspect concealed runs without destructive access.
- 3
Targeted repair or replacement. Based on findings, we seal accessible leaks with mastic, replace damaged flex or metal sections, and reinforce structural supports. For metal duct in historic Columbus homes, we fabricate matching gauge patches rather than replacing entire runs unnecessarily.
- 4
Insulation restoration. Where original insulation has compressed, torn, or moisture-damaged, we install new insulation sized to the duct diameter and secured with proper mechanical fasteners — not just tape that will fail. This step is especially critical for attic ductwork in Columbus’s climate of 90°F summers and sub-zero winter nights.
- 5
Post-repair verification. We re-test static pressure and run the system through heating and cooling cycles to confirm even airflow at all registers, proper temperature differential across the air handler, and no residual leaks. You’ll receive documentation of before-and-after conditions for your records.
How Much Does Duct Repair & Sealing Cost in Columbus?
Duct sealing for a typical 1,500–2,500 square foot Columbus home runs $350–$650 when accessible ductwork in basement or crawl space needs mastic sealing at joints and register boots. Flex duct repair or replacement in an attic or crawl space typically ranges $200–$450 per section depending on length, diameter, and access difficulty. Metal duct repair with custom fabrication starts around $400–$950 for rusted or separated runs, with full replacement of extensive damaged systems running higher.
Several factors move pricing within these ranges. Accessibility is the largest — a basement with a standard ceiling height in Westerville takes half the time of a tight crawl space in Grandview Heights. Extent of damage matters: sealing ten joints differs from replacing thirty feet of crushed flex duct. Insulation condition adds cost when original wrapping must be removed and replaced to access the duct beneath. And system size scales the work — a 5-ton system with 18-inch trunk lines requires more material than a 2.5-ton system with 14-inch ducts.
To avoid overpaying, get an estimate that specifies exactly which runs will be sealed or replaced, what materials will be used, and whether post-repair testing is included. Some Columbus-area contractors quote low and charge extra for “unexpected” additional sealing. At Summit, our free estimate covers the full scope — Michael inspects your system personally, identifies every issue, and quotes the complete repair with no hidden charges.
