Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Repair & Sealing Across Elmhurst
Most duct repair and sealing jobs in Elmhurst run $380-$1,200 per system depending on access difficulty and whether metal, flex, or mastic work is needed. Our crews coordinate dispatch from our Chicago office and carry the flexible camera systems and extended reach tools that Elmhurst’s split-level and ranch homes demand. Call (708) 683-3974 for a written estimate before any work starts.
We’ve worked in Elmhurst since 2013, and the housing stock here is unlike neighboring suburbs. The postwar building boom filled blocks with ranch homes and split-levels, many with original galvanized or early sheet-metal ductwork now 50-70 years old. Meanwhile, the teardown-and-rebuild wave driven by District 205 school demand keeps pushing construction dust through aging systems. That dual pressure, specific to Elmhurst’s real-estate cycle, is why we scope every job with a camera-first inspection and quote per system, not per vent.

Our Duct Repair & Sealing Services in Elmhurst
Duct Sealing
Sealing in Elmhurst starts with finding every leak point, and that is harder here than in neighboring Villa Park or Lombard. In the 1960s split-level neighborhoods near York Road and Wilder Park, duct branches frequently dead-end inside finished wall chases and under half-level stairwells. A sealing scope that works in a ranch will miss these leak points. We run camera inspection before quoting, then seal with mastic and mechanical fasteners, verifying with negative-pressure testing while the system runs. Per-system pricing, agreed in writing before any panel comes off.
Metal Duct Repair
Elmhurst’s 1950s-1970s ranch and split-level stock includes original galvanized sheet-metal systems, some converted from gravity hot-air “octopus” furnaces. These feature complex branching into wall cavities and under stairwells that creates debris pockets and corrosion points standard equipment misses. We repair separated seams, replace rusted sections with matching gauge metal, and support sagging trunk lines. Every repair is photographed and included in the documented photo record.
Flex Duct Repair
Later additions and basement conversions in Elmhurst often use flex duct, and the humid summers here, sustained relative humidity above 70%, degrade the inner liner faster than in drier climates. We replace collapsed or torn flex sections with new insulated duct, seal connections with approved mastic, and verify airflow at each register. The repair is scoped per system, not per foot, with the full price in writing before work begins.
Air Leak Repair
Air leaks in Elmhurst homes waste conditioned air into wall cavities, attics, and the gaps beneath split-level stairwells. We pressurize the system, locate leaks with smoke testing and thermal imaging, then repair with mastic sealant and mechanical reinforcement. In multi-system homes common near the older craftsman blocks off York Road, we scope and quote each air handler separately. No system gets skipped because a technician assumed a single-system layout.
Duct Insulation
Uninsulated or degraded ductwork in Elmhurst’s unconditioned basements and crawl spaces loses efficiency through long heating seasons that run October through April. We install foil-faced insulation with sealed vapor barriers, paying special attention to trunk lines that pass through garage ceiling chases or exterior wall cavities where temperature differentials are extreme.

BeforeAfterTrusted Brands We Service in Elmhurst
Our equipment roster includes Rotobrush agitation systems, Nikro negative-pressure extractors, and Honeywell airflow verification tools. We stock common repair parts for Elmhurst’s prevalent systems, including mastic, mechanical fasteners, and matching gauge sheet metal. That local inventory means faster turnaround on repair jobs, not a return visit because a fitting had to be ordered. Customers can look up each brand independently to verify specifications before agreeing to a price.
Common Duct Repair & Sealing Problems We See in Elmhurst Homes
- Disconnected branches inside finished wall chases. In the 1960s split-levels near Wilder Park, we opened a chase beneath a half-level stairwell and found a disconnected galvanized branch blowing heated air straight into the wall cavity. The original octopus-furnace conversion left it unsupported. We reconnected and sealed it with mastic, then verified the repair with camera inspection while the system ran under negative pressure with HEPA filtration at the air handler. The homeowner’s cold second-floor bedroom finally held temperature, and the blower motor stopped short-cycling.
- Sealing without addressing biological growth first. Humid Chicago-area summers, sustained relative humidity above 70%, cultivate mold and mildew inside duct interiors. Sealing over these surfaces traps spores rather than removing them. We clean before sealing, with the photo record showing the difference.
- Under-scoped quotes on multi-system homes. Many Elmhurst homes near the District 205 boundary run two or three separate systems. A technician accustomed to single-system ranches may quote one air handler and miss the others entirely. We verify the count during initial inspection and quote per system.
- Construction dust infiltration from neighboring teardowns. Elmhurst’s sustained rebuild wave means aging duct systems repeatedly absorb heavy particulate from adjacent construction. Sealing alone doesn’t address accumulated debris; we assess whether cleaning and repair are both needed before quoting scope.
Pricing for Duct Repair & Sealing in Elmhurst, IL
A typical duct sealing job in Elmhurst runs $380-$720 per system for accessible trunk and branch work with mastic and mechanical reinforcement. Metal duct repair, including section replacement and seam rebuilding, ranges $550-$1,200 per system depending on access difficulty and material gauge. Flex duct replacement in finished chases runs $280-$480 per run. Air leak detection and repair with pressurized smoke testing starts at $420 per system.
These are whole-system prices, agreed in writing before work starts under Haven Standard Clause 1. We do not quote per vent or advertise teaser rates that balloon on arrival. Every estimate includes the documented photo record as a standard deliverable, not an add-on.
Factors that move Elmhurst jobs toward the higher end: multiple access cuts through finished walls or ceilings in split-levels, three or more separate HVAC systems, original galvanized metal requiring custom fabrication, and repairs in unconditioned spaces where insulation replacement is also needed. Call (708) 683-3974 for a written estimate, exact to your home’s layout.

FAQs - Duct Repair & Sealing in Elmhurst
Duct branches in 1960s Elmhurst split-levels frequently dead-end inside finished wall chases and beneath half-level stairwells, a floor-plan quirk of that era’s construction. Technicians accustomed to simple ranch layouts in Villa Park or Lombard often underestimate these hidden runs, requiring longer flexible tools and extra access cuts to reach and seal leak points properly. We camera-inspect before quoting so the scope includes every branch, not just the visible trunk. Call (708) 683-3974 for a written estimate that accounts for your home’s actual layout.
Each system is scoped, quoted, and documented separately. A typical Elmhurst home with three air handlers, common in larger properties near the District 205 boundary, runs $1,140-$2,160 for full sealing across all systems. We verify the count during initial inspection; no system gets skipped because a technician assumed a single-system layout. The written price for each system is delivered before any work starts. Call (708) 683-3974 to schedule inspection.
Every CleanRun job concludes with a Documented Photo Record of every duct run, before and after, delivered as a standard job record. For sealing work, we also include negative-pressure test results showing measured leakage reduction and a written scope describing each access point opened, each branch sealed, and each repair verified. This is a concrete deliverable, not a vague reassurance. Haven Standard Clause 1 requires the written price before work; the photo record verifies the work was performed as scoped.
Yes. Construction particulate accelerates duct degradation and can infiltrate through existing leaks, making cleaning and sealing a combined need rather than sealing alone. We assess accumulated debris during camera inspection and scope accordingly. Sealing without cleaning traps particulate inside the system. The photo record shows what was found and what was removed before any sealant was applied. Call (708) 683-3974 for an inspection that addresses both contamination and leakage.
Repair is viable when corrosion is localized, seams are separable, and the trunk geometry is sound. Replacement becomes the better value when rust is generalized, multiple branches have failed at joints, or the original “octopus” conversion left unsupported drops that continue to sag. We camera-inspect and provide a written comparison of repair versus replacement costs, with the photo record showing the actual condition found. No recommendation without evidence.
