We’ve been working in Palatine since 2013, and the housing stock here tells its own story. The split-levels and ranches built during the 1960s and 1970s Northwest suburban expansion carry duct systems that are now 40 to 60 years old - sheet-metal trunk-and-branch layouts with internal fiberglass ductboard liner that was standard for the era. That liner doesn’t age gracefully. Our Duct Repair & Sealing crews know what to look for before a single panel comes off.

Our Duct Repair & Sealing Services in Palatine
Duct Sealing
Sealing in Palatine means addressing decades of thermal cycling in original sheet-metal systems. The six-month heating season from October through April forces expansion and contraction at every joint. We seal with mastic compound and reinforced mesh at failing seams, particularly where trunk lines transition to branch runs in the partially conditioned spaces common to Palatine split-levels. Aerosol-based duct sealing is available for systems with limited access, though we evaluate whether the underlying ductboard liner can support a lasting seal before recommending it.
Flex Duct Repair
Flex duct in Palatine is often found in later additions or basement retrofits, not the original 1960s-70s builds. Where flex has been substituted for failing rigid duct, we find kinks at support points and collapsed sections where the inner liner has degraded. We replace compromised flex with properly sized, insulated runs and secure them with mechanical fasteners - not tape alone - to prevent the sagging that recreates the same problem.
Metal Duct Repair
Original galvanized steel trunk lines in Palatine’s ranch and colonial stock corrode at seams and where condensate has collected in low points. We cut out damaged sections, fabricate replacement pieces to match existing dimensions, and seal with mastic. In homes with whole-home bypass humidifiers - standard 1970s equipment here - the supply plenum downstream of the humidifier often shows the worst corrosion from decades of mineral-laden moisture exposure.
Duct Insulation
Uninsulated or degraded-insulation supply runs in Palatine crawl spaces and attics lose conditioned air before it reaches the register. We re-insulate with foil-faced fiberglass wrap or closed-cell foam where moisture intrusion has destroyed the original jacket. This matters particularly in split-levels where ductwork routes through crawl areas prone to pest access and humidity - conditions that taping alone won’t address.
Mastic Sealant Application
Mastic is our primary sealing method for Palatine’s older metal systems. Water-based mastic compound, applied with brush or spray and reinforced with fiberglass mesh at joints, outlasts foil tape by decades in the temperature swings these ducts experience. We specify mastic for every seam repair in systems over 30 years old, which describes most of the housing stock between Palatine Road and Rand Road.
Air Leak Repair
Leak detection starts with pressure testing and smoke tracing to locate the source, not guesswork. In Palatine homes, we most often find leaks at the plenum connection, at trunk-to-branch transitions, and where original ductboard liner has delaminated from the metal shell. Each leak source gets a specific repair documented in the written scope and photographed.

BeforeAfterTrusted Brands We Service in Palatine
Our crews arrive with professional-grade equipment from Nikro, Honeywell, Aprilaire, and Abatement Technologies - brands recognized in the HVAC trade for negative-pressure extraction, HEPA filtration, and air quality control. We stock common sealing and repair materials for Palatine’s dominant system types, which means most jobs don’t wait on parts. For whole-home bypass humidifiers still in service on 1970s furnaces, we carry Aprilaire replacement components and can evaluate whether the unit is worth maintaining or should be decommissioned as part of the sealing scope.
Common Duct Repair & Sealing Problems We See in Palatine Homes
- Delaminated ductboard liner shedding fiberglass particles. The internal fiberglass lining in Palatine’s original 1960s-70s ducts breaks down into a porous, particle-trapping surface that releases debris every time the blower cycles. Camera inspection reveals the extent before any sealing work begins.
- Mineral scale and biological growth from whole-home bypass humidifiers. These units were standard on 1970s Palatine furnaces. Decades of operation leave the humidifier drum and downstream supply plenum coated with contamination that reseeds the entire duct system if not addressed during repair.
- Moisture intrusion in split-level crawl-space duct runs. Ductwork routed through partially conditioned utility spaces in Palatine’s common split-level design faces humidity, pest access, and joint separation that tape repairs won’t survive. Mastic sealing and re-insulation are required.
- Corroded seams from six-month heating-season condensation. Northwest Cook County’s hard winters mean forced-air systems cycle heavily for half the year. Condensate collects at low points in metal trunk lines, accelerating corrosion at seams and connections.

FAQs - Duct Repair & Sealing in Palatine
Most 1960s Palatine ductwork can be sealed and returned to service if the galvanized steel shell is structurally intact. The critical factor is the condition of the internal ductboard liner. If it has delaminated and is shedding particles, we remove the degraded liner with HEPA-controlled agitation, then seal the bare metal with mastic and re-insulate. Full replacement becomes necessary only when the metal itself is corroded through or when access is so restricted that sealing cannot be verified. We make that determination with a camera inspection and give you a written price for either path. Call (224) 344-8881 to schedule the inspection.
Palatine’s housing stock was built between 1955 and 1985 with internal fiberglass ductboard liner that degrades into a porous, particle-trapping surface over 40-60 years. South Barrington’s newer homes use smooth metal or flex duct without this liner, and their systems haven’t experienced the same thermal cycling. The degraded ductboard in your Palatine home acts like a reservoir - every cleaning or disturbance releases trapped debris until the liner is either removed or sealed. We document this condition with before-and-after photography so you can see the difference between surface cleaning and actual source removal.
Yes, and it’s a factor we evaluate on nearly every Palatine job of this era. Decades of humidifier operation leave mineral scale and biological growth on the drum and in the supply plenum directly downstream. Sealing ducts without addressing this contamination point means the growth reseeds the system after we leave. Our scope typically includes humidifier decommissioning or component replacement, plus plenum cleaning and sealing, as part of a lasting repair. The condition is photographed and included in your documented photo record.
Shared systems require coordination with building management and sometimes with neighboring units, particularly where trunk lines serve multiple floors. We work from as-built mechanical drawings when available, or we trace the system with cameras to identify which runs serve which units before sealing. Our written scope specifies exactly which portions of the shared system are included, and we schedule around building access restrictions. For buildings with shared dryer vent stacks - common in Palatine’s denser multifamily housing near the Metra corridor - we evaluate the full stack for blockages that affect multiple units.
Shared-stack buildings concentrate lint and moisture from multiple units into a single vertical run, creating fire hazards and back-pressure problems that individual unit cleaning won’t solve. We inspect the full stack with a camera from the roof or common access point, identify blockages or separations, and repair with the building’s management involved. The repair is documented with photos of the full stack condition, not just the individual connection. This is standard practice for our crews in Palatine’s condo and townhome stock near the downtown core.
