Our Duct Repair & Sealing Services in Brighton Park
Mastic Sealant Application
Brighton Park bungalows were built with gravity-fed “octopus” furnaces and later converted to forced air. Those conversions left behind oversized main trunk lines with seams that were never properly sealed for pressurized airflow. We apply professional-grade mastic sealant - not duct tape, which degrades in months - to close gaps where unconditioned basement or attic air leaks in. On a typical Brighton Park job, we’ll seal 40 to 80 linear feet of original sheet-metal seam. A full mastic sealing runs $320-$480 for a single-family bungalow, $450-$680 for a two-flat with separate systems.
Metal Duct Repair
The heavy-gauge sheet metal in pre-1945 Brighton Park homes was built to last, but it’s not immune to Chicago’s freeze-thaw cycles. We see loosened seams, corroded boot boxes under floor joists, and original plenum boxes that have settled or cracked. Our Duct Repair & Sealing team fabricates custom patches and replacement sections on-site using tools from Rotobrush and Nikro. Metal duct repair in Brighton Park typically costs $280-$520 depending on accessibility and the extent of corrosion.
Air Leak Repair
Leaky ducts in Brighton Park pull in more than lost efficiency. Given the neighborhood’s proximity to light-industrial and rail-corridor activity along the perimeter, unsealed returns draw in higher particulate loads than you’d find in outer suburbs. We pressure-test the system, identify leak points with smoke pencils and thermal imaging, then seal them properly. Air leak detection and repair runs $250-$450 for most Brighton Park homes, with camera verification before and after.
Flex Duct Repair
Some Brighton Park homes have had partial flex-duct additions in attics or additions. Flex duct crushes, disconnects, or develops tears at the collar. We replace damaged sections with properly sized flex and secure them with mechanical fasteners and mastic - never zip ties alone. Flex duct repair is typically $180-$340 per run.
Duct Insulation
Uninsulated ductwork in Brighton Park basements and crawl spaces loses heated air before it reaches the register. We wrap accessible trunk lines with formaldehyde-free insulation, sealed at all seams. Duct insulation runs $380-$620 for a typical bungalow’s accessible runs.

Trusted Brands We Service in Brighton Park
We stock parts and specify equipment from the same brands serious HVAC contractors use: Rotobrush contact tools for deep sediment extraction, Honeywell zone controls where we’re balancing airflow between floors, and Aprilaire media air cleaners when a Brighton Park home needs filtration upgrade alongside sealing work. We don’t order parts from a catalog while you wait. Our trucks carry the common fittings, collars, and sealants for Chicago’s vintage housing stock, which means most Brighton Park jobs finish in one visit.
Common Duct Repair & Sealing Problems We See in Brighton Park Homes
- Missing or degraded mastic on original sheet-metal seams. Chicago’s freeze-thaw cycles expand and contract metal ductwork seasonally. In Brighton Park bungalows, this loosens the old paste or tar that was never meant for forced-air pressure. Gaps open. Unconditioned basement air pulls in. Heating bills climb 15 to 25 percent before most owners notice.
- Improper sealing of boot boxes under floor joists in two-flats. Brighton Park’s brick two-flats often have two entirely separate forced-air systems, but boot boxes and chase walls sometimes share space. When one unit’s leaks aren’t sealed, you get cross-contamination between units - odors, temperature imbalance, and efficiency loss for both parties.
- Deep sediment in cast-iron plenum boxes from octopus-furnace conversions. These broad, flat reservoirs sit buried in the floor system, predating the current furnace by 30 or 40 years. Standard vacuum wands can’t reach the compacted debris. Without custom contact tools, the sediment recontaminates the system within weeks of any surface-level repair.
- Oversized main trunk lines creating turbulent airflow and whistle leaks. The ductwork in Brighton Park bungalows was engineered for gravity convection, not blower pressure. Air moves too slowly in oversized trunks, creating positive pressure at seams that were never meant to hold it. Mastic alone won’t fix the physics; we often need to section and balance the trunk for proper airflow.

FAQs - Duct Repair & Sealing in Brighton Park
They’re leftovers from gravity-fed “octopus” furnace conversions done in the 1950s-1970s, buried in the floor system and never removed because they were too heavy to extract without structural work. We reach them with Rotobrush contact tools that standard vacuum wands can’t match, extract the compacted sediment, then seal the plenum and its connections with mastic to prevent recontamination. Call (877) 502-3903 if you suspect your bungalow has one - we’ll camera-inspect and show you.
Chicago’s winter-spring temperature swings expand and contract the metal framing and joists that support ductwork, loosening seams and cracking aged mastic that was already brittle. Brighton Park’s 1910s-1940s construction means less insulation between structural members and ducts, so the metal feels every degree shift. We use flexible, fiber-reinforced mastic rated for temperature cycling, applied thicker at known stress points. For a full inspection of your system’s seal integrity, call (877) 502-3903 - estimates are free.
Yes. We isolate each system at the furnace and seal only the active ductwork for the unit we’re contracted to service. In Brighton Park two-flats, we commonly find shared chase walls where boot boxes leak between units; we seal those common areas with both parties’ permission, but we never access a unit we aren’t hired to work on. If you’re a landlord or tenant in a Brighton Park two-flat, call (877) 502-3903 and we’ll walk through the logistics before scheduling.
Water-based, fiber-reinforced mastic applied with a brush or caulking gun at 1/8-inch thickness minimum. Duct tape fails in months; aerosol sealants don’t adhere well to the oil residue on vintage sheet metal. For Brighton Park’s oversized trunk lines, we sometimes combine mastic with mechanical fasteners at high-pressure seams. The material runs $45-$85 per gallon, and a typical bungalow uses two to four gallons. We include all materials in our upfront quote - call (877) 502-3903 for yours.
Our technicians are used to it. We schedule arrival windows that avoid school traffic on major corridors, carry equipment in wheeled cases that fit through alley gates, and confirm parking arrangements when you call. Most Brighton Park homes have basement access through the rear, so street parking isn’t always necessary. We don’t charge extra for the extra time it takes to navigate a tight block. If you’ve got alley access or specific parking concerns, mention them when you call (877) 502-3903 and we’ll plan around them.
