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.

We’ve handled our Duct Repair & Sealing in Schaumburg long enough to recognize the patterns. The 1990s-era subdivisions near Meacham Road often show flex duct that has sagged at the elbows, creating pockets where conditioned air never reaches the register. Newer construction around the Renaissance Convention Center area tends toward tight ductwork with seal failures at the plenum connections, the large distribution box where the main trunk meets the furnace. In both cases, the symptom is the same: rooms that never match the thermostat, utility bills that climb without explanation, and systems that run longer to deliver less. Our crews document what they find with before-and-after photography of every duct run, included as a standard deliverable on every job.
Tomas Reyes established CleanRun in 2013 under the H.A.V.E.N. Standard, and we’ve held to one practice since the first truck rolled out: every job gets a written price before any work starts, every time. No exceptions. Haven Standard Clause 1 is the foundation of that promise. When you call (224) 385-0904, you’ll speak to a live person, 24/7, and we’ll schedule a technician who arrives in uniform, background-checked, and identified by name before they reach your door.
What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, cracks, and separation points in your forced-air distribution system where heated or cooled air escapes before reaching your rooms. In Schaumburg, we commonly find seal failures at the plenum connections and where metal trunk lines meet drywall penetrations, especially in homes built during the 1980s and 1990s construction boom. Our crews use professional-grade mastic sealant and metal-backed tape rated for HVAC applications, not the cloth-backed tape that degrades within months. Every sealed joint is photographed before and after, and the images are delivered as part of your job record.

Flex Duct Repair
Flex duct, the ribbed plastic tubing with fiberglass insulation that runs through attics and crawl spaces, collapses, tears, or disconnects over time. In Schaumburg’s climate, attic temperatures swing from below zero in January to well over 120 degrees in July, accelerating the deterioration of the outer vapor barrier and the inner liner. We replace damaged sections with new flex duct sized to match your system’s CFM requirements, the airflow volume measured in cubic feet per minute, and we support it with proper strapping to prevent the sagging that creates airflow restrictions. The camera shows you exactly where the damage was and what the new run looks like.

Metal Duct Repair
Galvanized steel ductwork, common in older Schaumburg homes and in basement trunk lines, rusts at the seams, separates at the drive cleats, and can develop holes from corrosion or physical damage. We repair metal duct by cutting out deteriorated sections and fabricating replacement pieces on-site, then sealing with mastic and mechanical fasteners rated for the pressure class of your system. When we encounter metal duct in Schaumburg basements-nearby Hoffman Estates Duct Repair & Sealing is a similar story-we often find previous repairs done with duct tape that has dried and fallen away, leaving the homeowner with no idea air has been leaking for years. Our photo record makes that history visible.

Duct Insulation
Uninsulated or poorly insulated ductwork in unconditioned spaces, attics and crawl spaces especially, loses 20-40% of its thermal energy before the air reaches your rooms. In Schaumburg, where winter design temperatures hit minus 10 degrees and summer humidity pushes cooling systems hard, this translates to furnaces that run constantly and air conditioners that can’t keep up on the hottest August afternoons. We install fiberglass duct wrap with a reinforced foil vapor barrier, sealed at every seam with matching foil tape, to bring your ductwork up to current energy code standards. The improvement shows in your utility bills and in the even temperatures from room to room.

Mastic Sealant
Mastic is a thick, water-based compound brushed or troweled onto duct joints, then curing to a flexible, durable seal that outlasts tape by decades. We apply mastic to every accessible joint in your duct system, the plenum connections, trunk line seams, branch takeoffs, and register boots, using a product rated for the temperature range your system operates in. In Schaumburg homes with fiberglass duct board, mastic is the only appropriate sealing method, as tape adhesives fail to bond properly to the porous surface. The work is messy and slow, which is why cheap competitors skip it. We don’t skip it, and we photograph every application so you can verify the coverage.

Air Leak Repair
Air leaks in ductwork are often invisible to the homeowner, detectable only through temperature differences between rooms, dust patterns near ceiling registers, or utility bills that trend upward without explanation. We pressurize your duct system and use smoke pencils or theatrical fog to trace leak paths, then repair each one with the appropriate method for the duct material, mastic for metal, proper connectors and support for flex, replacement sections for damaged duct board. In Schaumburg’s competitive housing market, where homes sell quickly and inspections are thorough, documented air leak repair can prevent the surprises that delay closings. Our photo record becomes part of your home’s maintenance history.

Brands We Service for Duct Repair & Sealing

We’ve serviced and sealed ductwork connected to hundreds of Honeywell air cleaning systems in Schaumburg and the surrounding suburbs, including our Duct Repair & Sealing in Elk Grove Village, working on the F100 and F200 media air cleaners and the electronic air cleaners common in homes built during the 2000s. We stock the OEM gaskets and transition fittings for these units, so when seal failure occurs at the air cleaner cabinet, we can repair it without a return trip. The same applies to Aprilaire whole-house humidifiers and dehumidifiers, which we see frequently in Schaumburg’s newer construction where tight building envelopes trap moisture and precise humidity control protects both the structure and the occupants.
Our equipment roster includes Rotobrush negative-pressure extraction systems and Nikro HEPA-filtered vacuums, tools we use during duct repair and sealing to remove the debris that accumulates at leak points before we close them. Whether you have a Honeywell, Aprilaire, or any other make of HVAC component connected to your duct system, we can assess the integration points, identify where seal failure is occurring, and repair it with documentation you can verify. Guardsman-treated flex duct, where the antimicrobial liner is specified, requires specific handling to preserve the treatment integrity, and our crews are trained to those manufacturer specifications.
Before
AfterSigns You Need Duct Repair & Sealing Right Now
- Uneven temperatures from room to room. When your bedroom is ten degrees colder than your living room in January, or your upstairs never cools below 78 in July, the duct system is likely leaking or obstructed. In Schaumburg’s split-level and tri-level homes, common in the neighborhoods west of Roselle Road, this pattern often traces to a disconnected flex duct in the attic or a failed seal at the plenum.
- Dust accumulation near ceiling registers. If you wipe your register covers weekly and they’re dirty again in days, air is pulling attic or wall-cavity debris into the system through leaks on the return side. The dust you see is a visible indicator of a larger problem: your system is filtering and distributing air from unconditioned spaces, not just your living areas.
- Utility bills that rise without explanation. A 20% increase in your ComEd or Nicor bill, with no rate change or thermostat adjustment, often signals duct leakage forcing your equipment to run longer to achieve the same result. We’ve documented this in Schaumburg homes where sealing alone reduced heating runtime by 25%.
- HVAC system that runs constantly or short-cycles. Constant running suggests the system can’t reach setpoint because conditioned air is escaping. Short-cycling, where the system turns on and off rapidly, can indicate a severely restricted duct run causing the equipment to overheat or freeze up and trigger safety limits. Both patterns strain components and shorten equipment life.
- Musty or stale odors when the system operates. Air pulled through wall cavities or crawl spaces carries the organic material that supports mold growth, especially in Schaumburg’s humid summer months when crawl space moisture peaks. If the smell intensifies when the blower starts, you have a return-side leak that needs immediate attention.
Our Duct Repair & Sealing Process - Step by Step

- 1
Written estimate before any work begins. Our technician arrives at your Schaumburg home, inspects the accessible ductwork, and identifies the specific repairs needed. You’ll receive a written price with line-item detail before any panel comes off or any sealant is opened. Haven Standard Clause 1 requires this, and we’ve operated this way since 2013. No surprises, no pressure, no “call for a quote” runaround.
- 2
Photographic documentation of existing conditions. Before touching anything, we photograph the interior of every duct run we’ll be working on, using a borescope camera that sends images to a display you can watch in real time. This establishes the baseline and often reveals problems the homeowner wasn’t aware of, a collapsed flex section behind a finished basement ceiling, for example, or rust scaling in a metal trunk line.
- 3
Targeted repair and sealing with trade-appropriate materials. We match the repair method to the duct material and the failure mode. Mastic for metal seams. Proper connectors and support straps for flex duct. Replacement sections for duct board or metal that has deteriorated beyond repair. Every material we use is rated for the temperature and pressure conditions of residential HVAC, and we name the brands on your invoice so you can verify specifications independently.
- 4
Post-repair photography and system testing. After repairs are complete, we photograph every duct run again to document the finished work. We then run the system and verify airflow at each register, using a calibrated anemometer to measure velocity in feet per minute. If the numbers don’t match our expectations, we find out why before we leave.
- 5
Delivery of your job record and activation of the 365-Day Done Right Promise. You receive a complete record: before-and-after photos of every duct run, the written scope of work, the materials used, and the 365-Day Done Right Promise in writing. If anything we repaired fails within that year, we make it right. Not a policy subject to manager approval. A written guarantee.
How Much Does Duct Repair & Sealing Cost in Schaumburg?
A typical duct sealing job in Schaumburg runs $280-$480 for a single-story home with accessible basement ductwork, where we can reach the plenum, trunk lines, and branch takeoffs without demolition. Flex duct repair, when a single run has collapsed or disconnected in an attic or crawl space, typically falls in the $180-$340 range per run. Metal duct repair involving section replacement and custom fabrication runs higher, usually $420-$780 depending on the linear footage and the complexity of the access. Full-system sealing in a larger Schaumburg home, 3,000 square feet or more with ductwork in multiple unconditioned zones, can range from $680-$1,200.
Several factors move these numbers. Accessibility is the largest: ductwork buried behind finished basement ceilings or tucked into tight attic kneewalls requires more time and sometimes temporary access panels. The material matters too, metal duct repair involves cutting, fitting, and sealing, while flex duct replacement is more straightforward but requires proper sizing and support. The extent of the damage affects both labor and materials; a single disconnected register boot is a quick fix, while a plenum that has separated from the furnace cabinet may require partial disassembly of the HVAC unit.
To avoid overpaying, get any estimate in writing with line-item detail, and be wary of per-vent pricing or teaser rates that don’t cover the actual scope. At CleanRun, we deliver one flat price per system, agreed before work starts, with no per-vent add-ons. Our free estimate includes the full inspection, the photographic documentation, and the written scope. If you have a competitor’s written estimate, bring it; under our Free Second Opinion policy, we’ll put our number next to it at no charge.

Frequently Asked Questions - Duct Repair & Sealing in Schaumburg

Duct repair and sealing is the process of fixing physical damage to your forced-air distribution system and closing the gaps where conditioned air escapes into unconditioned spaces like attics, crawl spaces, and wall cavities.
