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 Arlington Heights
Duct repair and sealing in Arlington Heights typically runs $280-$680 for most single-family homes, with flex duct replacement starting around $340 per run and full trunk re-sealing with mastic reaching the upper end of that range. Our crews dispatch daily to Arlington Heights from our Chicago office, carrying Rotobrush and Nikro equipment sized for the tight mechanical rooms and shared chases common in the village’s 1950s-1970s housing stock. Call (224) 385-0904 for a written estimate before any work begins.
Arlington Heights built out fast and dense during the postwar boom. The ranches and raised split-levels that define the village - from the established neighborhoods near downtown to the blocks along Rand Road and Palatine Road - share a common problem: original galvanized trunk-and-branch ductwork that has cycled through six decades of sub-zero winters and humid summers without professional attention. That thermal stress cracks seals, degrades insulation, and creates the pressure losses that show up as whistling registers, hot and cold rooms, and furnaces that run longer than they should. We’re familiar with these homes because we’ve worked inside them since 2013.

Our Duct Repair & Sealing Services in Arlington Heights
Duct Sealing with Mastic Sealant
The original foil tape and mastic on Arlington Heights’s 1950s-1970s galvanized trunk-and-branch systems cracks and separates after decades of thermal cycling. Our Duct Repair & Sealing team removes the degraded material, cleans the joint surfaces, and applies fresh mastic sealant rated for the temperature swings these systems endure. We photograph every joint before and after. A typical mastic re-sealing job in Arlington Heights runs $280-$480 for a standard ranch or split-level.
Flex Duct Repair
Flex duct in Arlington Heights attics and crawl spaces degrades from the inside out - the plastic liner becomes brittle, the wire helix corrodes, and the insulation compresses. We replace compromised flex runs with new R-8 insulated duct, sizing the length to avoid the kinks and sag that restrict airflow. Flex duct replacement in Arlington Heights typically costs $340-$520 per run, depending on attic access and length. We carry Guardsman flex duct and fittings on our trucks for same-day completion in most cases.
Metal Duct Repair
Galvanized steel trunks in older Arlington Heights homes develop rust at low points where condensation collects, and seams open from decades of expansion and contraction. We patch or replace damaged sections, re-seal with mastic, and re-insulate to prevent the thermal losses that drive up heating bills. Metal repair jobs range $380-$680, with full trunk replacement reaching higher only when the damage is extensive. We assess with a camera first, show you the footage, and quote in writing before cutting anything.
Duct Insulation & Air Leak Repair
Degraded duct insulation in Arlington Heights’s unconditioned basements and attics costs homeowners in two ways: heated or cooled air escapes before reaching the registers, and the thermal differential creates condensation that breeds mold. We remove compromised insulation, seal all accessible leaks with mastic, and install new fiberglass or foil-faced insulation to current standards. Full re-insulation of a standard Arlington Heights system runs $480-$860. For homes with the original asbestos-containing duct wrap - common in pre-1978 construction - we coordinate with certified abatement specialists before touching the system.

BeforeAfterTrusted Brands We Service in Arlington Heights
Our trucks carry professional-grade equipment from trade-recognized brands: Rotobrush agitation systems for mechanical debris removal, Nikro negative-pressure extractors for controlled containment, and Abatement Technologies HEPA filtration for fiber and particulate capture. For humidifier-related repairs - a frequent call in Arlington Heights, where Aprilaire whole-house humidifiers plumbed into plenums leave mineral scale that degrades seals - we stock Aprilaire replacement parts and can service or remove the unit as part of a duct repair scope. We don’t sell equipment we can’t document. Every brand we name can be verified independently before you agree to a price.
Common Duct Repair & Sealing Problems We See in Arlington Heights Homes
- Cracked mastic at trunk-and-branch joints. The original seals on 1950s-era galvanized systems in Arlington Heights fail predictably after 50-70 years of expansion and contraction. Air leaks at these joints rob the blower of static pressure, forcing longer run times and uneven heating.
- Delaminated fiberglass duct liner. In older neighborhoods near downtown Arlington Heights and the late-1950s subdivisions, the fiberglass liner inside galvanized trunks has separated from the metal after decades of thermal cycling. Standard brushing blows fragments into living areas; we use HEPA-controlled negative-pressure extraction instead.
- Shared vertical dryer vent stacks packed with lint. Because Arlington Heights built out so densely in the 1950s-1970s, many raised split-levels and ranches share a single vertical chase that carries both the furnace flue and the dryer vent stack. A duct repair call often turns into a stacked-vent sealing job that a neighboring town’s detached single-family grid rarely produces.
- Moisture intrusion at degraded air handler insulation. Arlington Heights’s humid continental climate produces heavy condensation on cooling coils in summer. Where duct insulation has degraded at the plenum connection, that moisture enters the system and creates recurring mold entry points.

FAQs - Duct Repair & Sealing in Arlington Heights
We can clean and inspect your portion of the shared stack, but effective sealing requires access to the full vertical run and termination point. In Arlington Heights’s dense 1950s-1970s buildings, these stacks often terminate through the roof or a common wall, so we coordinate with building management or adjacent unit owners before quoting. We document the full stack condition with photos and provide a written scope that identifies which sections are your responsibility versus common elements. Call (224) 385-0904 to schedule an inspection - estimates are free.
Original galvanized ductwork in Arlington Heights’s 1960s ranches typically needs re-sealing and re-insulation before it needs full replacement. The metal itself lasts; the failure points are the mastic joints, the degraded fiberglass liner, and rust at low spots where condensation pools. We camera-inspect first, show you the actual condition, and quote repair versus replacement in writing. Most of these systems are salvageable with proper sealing. Call (224) 385-0904 for an inspection and written estimate.
Yes - mineral scale from a neglected Aprilaire humidifier degrades seals at the plenum connection, corrodes metal surfaces, and creates airflow restrictions that force the system to work harder. We remove the scale, assess the plenum and adjacent ductwork for damage, re-seal with mastic, and can service or replace the humidifier as part of the scope. This is a common call in Arlington Heights, where whole-house humidifiers are standard but rarely maintained. Call (224) 385-0904 for a written quote.
Our Arlington Heights crews carry equipment sized for tight residential streets and park on the nearest legal curb space. We need access to your driveway or a 25-foot stretch of street parking for our van, and clear access to your basement mechanical room or utility closet.

We verify seal integrity with a pressure test after completion, document every sealed joint with before-and-after photos, and deliver both as part of your standard job record. The 365-Day Done Right Promise applies in writing: if a sealed joint opens or sealing fails within one year, we return and correct it. No manager approval required. No “policy” ambiguity. The standard is what we put in writing, photograph, and guarantee.
