What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, cracks, and disconnected joints that leak conditioned air into unconditioned spaces — attics, crawl spaces, and wall cavities. In Kansas, where summer humidity tops 70% and winter temperatures drop below 20°F, these leaks force your HVAC system to run longer cycles while delivering less comfort to your living spaces. We use professional-grade mastic sealant and metal-backed tape rated for thermal cycling, applied after pressure-testing to locate every leak — not the hardware-store foil tape that fails within two seasons.
Flex Duct Repair
Flex duct, common in Kansas homes built from the 1980s through the 2000s, collapses, tears, or disconnects at the collar joints where it meets metal trunk lines. We’ve replaced crushed flex runs in Overland Park ranch homes and reattached sagging sections in Lenexa basements where poor support straps let the duct pool on crawl space floors. Henry Wood carries replacement flex duct and proper tensioning tools on every truck, so we don’t need a return visit to complete the repair.
Metal Duct Repair
Galvanized steel ductwork in older Kansas homes — common in Prairie Village and Leawood mid-century builds — corrodes at seams, separates at slip joints, or cracks from thermal expansion stress. We cut out damaged sections, fabricate replacement pieces on-site, and seal with mastic and mechanical fasteners that outlast the original installation. Our Nikro negative-pressure vacuums capture metal particulate during cutting, keeping your home’s air clean during the repair process.
Duct Insulation
Uninsulated or degraded duct insulation in Kansas attics wastes enormous energy — attic temperatures reach 140°F in July while your cooled air travels through bare metal. We install foil-faced fiberglass insulation or closed-cell foam wraps rated for the temperature swings Kansas ductwork endures, with vapor barriers that prevent condensation mold growth. This is particularly critical for duct runs in unconditioned spaces common in Roeland Park and Mission split-level homes.
Mastic Sealant Application
Mastic is a water-based, fiber-reinforced compound that remains flexible after curing — the professional standard for sealing duct seams and joints against air leakage. We brush or trowel mastic onto every seam, joint, and penetration after cleaning the surface with Abatement Technologies particulate containment running, ensuring the bond adheres to bare metal without dust contamination. In Kansas’s freeze-thaw climate, this flexibility prevents the cracking that ruins tape-only repairs within months.
Air Leak Repair
Air leaks occur at register boots, return air plenums, filter cabinets, and where ductwork penetrates walls or floors — locations standard duct cleaning never addresses. We pressurize your system and use smoke pencils or thermal imaging to pinpoint leaks invisible to visual inspection, then repair with proper materials for each location. A typical Kansas home loses 20–30% of conditioned air to these leaks; our repairs routinely recover 15–25% of that loss.

Brands We Service for Duct Repair & Sealing
We’ve serviced and repaired duct systems connected to Aprilaire whole-house air cleaners and humidifiers across Johnson County and Wyandotte County, including integrated return air duct modifications that accommodate their media cabinets without restricting airflow. Our 17 years of Kansas-specific experience means we know how Aprilaire’s duct-mounted components interact with older metal trunk lines versus newer flex systems — and we stock the transition fittings that prevent the leaks common with aftermarket installations.
We also regularly repair ductwork serving Guardsman UV air treatment systems and Abatement Technologies HEPA filtration setups, particularly in homes where occupants have respiratory sensitivities requiring sealed, contaminant-controlled distribution. Whether your system includes these brands, Honeywell zone dampers, or any other make of HVAC equipment, Henry Wood diagnoses the ductwork integration points that cause performance problems. From cleaning to repair to sanitizing — handled in one visit.
Signs You Need Duct Repair & Sealing Right Now
- Rooms that never reach the thermostat setting. If your west-facing bedroom in a Kansas summer stays 8–10 degrees warmer than the hallway despite the AC running constantly, the duct serving that room likely has a significant leak or blockage. You’re paying to cool your attic instead of your bedroom.
- Dust accumulation immediately after cleaning. When fine dust reappears on surfaces within 24–48 hours of housecleaning, your return air ducts may be pulling attic or crawl space debris through gaps in the duct wall. In Kansas’s windy spring seasons, this problem accelerates dramatically.
- Unusually high energy bills with no rate increase. A duct system leaking 25% of its air forces your HVAC equipment to run 30–50% longer to achieve the same temperature. Kansas homeowners often notice this first in August when cooling loads peak and again in January during cold snaps.
- Visible gaps or disconnected ducts in attic or basement. If you can see daylight through duct seams, separated flex duct collars, or insulation hanging loose from bare metal, your system is hemorrhaging conditioned air. These visible defects represent the leaks large enough to see — smaller ones throughout the system compound the problem.
- Musty or chemical odors when the system runs. Leaky return ducts in crawl spaces or garages draw in musty air, exhaust fumes, or pesticide residues and distribute them throughout your home. In Kansas’s clay-soil areas where crawl spaces stay damp year-round, this creates persistent indoor air quality problems that cleaning alone cannot solve.
Our Duct Repair & Sealing Process — Step by Step
- 1
System inspection and pressure testing. Henry Wood arrives with a blower door and duct blaster to quantify exactly how much air your system is losing and locate the dominant leak paths. We document starting conditions with photos and airflow measurements at each register — no guessing, no selling based on fear.
- 2
Leak identification and repair planning. Using theatrical smoke and infrared cameras, we mark every leak location and prioritize repairs by impact. You’ll see exactly where your money is going before we start work, with line-item pricing for each repair zone.
- 3
Surface preparation and containment. We deploy Abatement Technologies HEPA filtration and negative air machines to contain particulates during cutting, grinding, or insulation removal. Your home’s air stays clean while we access dirty attic or crawl space ductwork.
- 4
Repair execution with professional materials. We replace damaged duct sections, apply mastic sealant to all seams, reinstall or upgrade insulation, and verify mechanical connections with proper supports. Every repair is photographed for your records and our quality documentation.
- 5
Post-repair verification and reporting. We re-test system pressure and measure airflow at each register to confirm performance improvement. You’ll receive before-and-after documentation showing leak reduction percentage and airflow recovery — proof the repair worked, not just a promise.
How Much Does Duct Repair & Sealing Cost in Kansas?
A typical Affordable Duct Repair & Sealing in Kansas, KS job runs $450–$850 for a single-system home with accessible attic ductwork, while flex duct replacement in a crawl space ranges $600–$1,200 depending on linear footage and access difficulty. Metal duct repair with section replacement and reseaming typically falls between $550–$950, and full duct insulation wrap for an unconditioned attic system runs $800–$1,400. These Kansas-specific ranges reflect our actual 2024–2025 job history, not national averages that ignore our regional labor and material costs.
Several factors move your price within these ranges: the accessibility of your ductwork (attic versus sealed crawl space), the extent of damage requiring replacement versus sealing only, whether your system needs cleaning before repair (mastic won’t bond to dusty metal), and the presence of asbestos-containing duct tape in pre-1985 Kansas homes that requires abatement protocol. We provide exact, itemized quotes after inspection — never ballpark figures that change on arrival. To avoid overpaying, beware of companies that quote duct sealing by the “system” without inspecting your specific layout, or that propose full duct replacement when targeted repairs would solve the problem. Our free estimate includes a written scope, fixed pricing, and no obligation to proceed. Call (855) 595-7944 to schedule.

Henry Wood will assess whether your Kansas home needs one or both during your free estimate.
