Why Bellows Air Duct & Vent Co. of Chicago Is Edgewater’s Preferred Duct Repair & Sealing Company
We’ve been serving Chicago homeowners since 2012, and Edgewater has been part of our route for decades. The neighborhood’s density of pre-war courtyard buildings and lakefront high-rises means we’ve developed specific expertise in retrofit duct systems that newer suburbs simply don’t have.
Our technicians know the difference between a purpose-built duct chase and a repurposed radiator void. They’ve repaired flex-to-metal splices in buildings where the original 1920s plaster is still intact and the ductwork was threaded through in 1978. That matters because Edgewater’s housing stock punishes generic solutions.
We answer calls with a live person, 24 hours a day. No voicemail tree, no app to download. Most Edgewater appointments are scheduled within 24 hours, and the majority of repairs are completed in a single visit. Our 90-Day Done Right Promise applies to every job - if it’s not right, we return at no charge with no paperwork required.
Ray Dempsey has built this company on one principle: say what you’ll do, do what you said, and stand behind it. That approach has kept us in business for over 42 years.
Our Duct Repair & Sealing Services in Edgewater
Duct Sealing
Air leaks in Edgewater’s older duct systems waste 20-30% of conditioned air before it reaches your rooms. In retrofitted courtyard buildings, we find leaks at original trunk-to-branch connections that have worked loose over decades of thermal cycling. Our sealing process starts with a camera inspection to map every breach, then we apply professional-grade mastic or mechanical seals depending on access and duct material. A typical duct sealing job in Edgewater runs $350-$550 for a single-family or two-flat, with larger courtyard buildings quoted after inspection.

Flex Duct Repair
Flex duct is the weak link in most Edgewater retrofit systems. The plastic inner liner degrades, the insulation compresses, and the wire helix corrodes in lakefront humidity. We recently serviced a 1928 courtyard building on Winthrop Avenue where the original galvanized trunk had a 1980s flex-duct splice near the return plenum. The junction was leaking air and collecting damp from Lake Michigan’s spring humidity, fostering mold inside the chase. We isolated the splice, applied mastic sealant, and insulated the flex section to prevent future condensation - saving the building owner from a costly duct replacement. Flex duct repair in Edgewater typically ranges from $180-$340 per section.

Metal Duct Repair
Original galvanized steel trunks in Edgewater’s pre-war buildings can last a century if maintained, but they corrode at seams and suffer punctures from decades of maintenance work in tight chases. We patch small breaches with matching sheet metal and sealant, reinforce failing seams, and replace short sections where corrosion has penetrated. Metal duct repair in Edgewater runs $250-$480 depending on access and extent of damage. When a trunk runs behind original plaster in a Kenmore Avenue courtyard building, we minimize disruption by working through existing access panels or creating small, repairable openings.

Duct Insulation
Uninsulated or degraded duct insulation in Edgewater’s lakefront buildings causes condensation that feeds microbial growth and reduces system efficiency. We install foil-faced fiberglass or closed-cell insulation appropriate to the duct material and chase conditions. In Sheridan Road high-rises with centralized HVAC trunks, proper insulation of main lines protects dozens of units from the humidity that rolls off Lake Michigan. Duct insulation work in Edgewater typically costs $300-$600 for residential systems.

Mastic Sealant Application
Standard foil tape fails within 2-3 years in Edgewater’s humid environment. We use water-based mastic sealants rated for HVAC applications, applied with brushes or sprayers to penetrate joints and create a permanent flexible bond. Mastic is essential for the flex-to-metal splices common in Edgewater’s retrofitted systems - tape simply cannot handle the differential expansion between materials. Mastic sealing as a standalone service runs $200-$400, or it’s included in our broader duct sealing and repair packages.

Trusted Brands We Service in Edgewater
We stock parts and specify equipment from Rotobrush, Honeywell, and Aprilaire - the same brands serious HVAC contractors have relied on for decades. For Edgewater’s older buildings, parts availability matters. A flex-duct splice in a 1930s three-flat may require adapters no longer in standard distribution, but our inventory includes transition fittings and custom fabrication options that keep jobs moving. Most repairs don’t require a return visit because our technicians arrive with the materials their experience tells them they’ll need.
Common Duct Repair & Sealing Problems We See in Edgewater Homes
- Flex-to-metal splices failing at junction points. The 1970s-80s retrofits in Edgewater’s courtyard buildings joined new flex duct to original galvanized trunks with tape or crude mechanical connections. These junctions collect lint, pet dander, and lakefront moisture, and they’re frequently missed by technicians unfamiliar with hybrid duct architecture. Mastic sealing is the only lasting fix.
- Kinked flex runs in tight interstitial spaces. Pre-war three-flats on corridors like Winthrop and Kenmore have ducts forced through voids never designed for HVAC. Kinked sections restrict airflow, create pressure imbalances, and eventually pull apart older joints downstream. We reroute or replace these sections with proper support and radius.
- Moisture accumulation in low-point sags. Edgewater’s lakefront humidity finds its way into poorly sealed duct systems and condenses in flex duct sags, particularly in spring and fall when lake temperatures diverge from air temperatures. Sealing alone won’t solve this - the duct must be cleaned, dried, and properly supported first.
- Centralized trunk degradation in Sheridan Road high-rises. Mid-century and later towers have main HVAC lines serving dozens of units. A single leak or insulation failure in these common trunks degrades air quality building-wide, yet building management often delays maintenance because access is complex and disruption affects many residents.

FAQs - Duct Repair & Sealing in Edgewater
Standard cleaning crews often miss the hybrid flex-to-metal junctions unique to Edgewater’s retrofitted systems, and they rarely reseal with mastic after disturbing connections. The 60660 zip code’s lakefront humidity then degrades tape or incomplete seals within 24-36 months. We camera-inspect these junctions specifically and apply mastic rated for coastal moisture conditions. Call (877) 502-3903 for an exact quote - estimates are free.
Yes. Shared return plenums and trunk lines in Edgewater’s multi-unit buildings mean a leak in one section pressurizes or depressurizes the entire system, pulling contaminants from wall cavities, basements, or neighboring units into the air stream. We’ve found single leaks in Kenmore Avenue buildings that were elevating particulate counts in units two floors away. We isolate and seal these breaches with camera verification. Call (877) 502-3903 for an exact quote - estimates are free.
We start with camera inspection through existing registers or small access points to locate leaks without unnecessary demolition. When we must open a wall, we cut discrete, repairable sections and restore plaster or match surrounding finishes. In many Edgewater buildings, we can seal accessible trunk sections from basement or attic spaces, avoiding interior wall intrusion entirely. Call (877) 502-3903 for an exact quote - estimates are free.
Yes, and often urgently. The temperature differential between Lake Michigan’s surface and conditioned air in exposed chases causes condensation that degrades insulation and promotes microbial growth. Sheridan Road towers with centralized systems particularly need main trunk insulation maintained - a single failure affects dozens of units. We inspect and replace insulation with materials rated for high-humidity environments. Call (877) 502-3903 for an exact quote - estimates are free.
A properly applied mastic seal on quality flex duct lasts 15-20 years in Edgewater’s conditions, compared to 2-3 years for foil tape. The key is surface preparation - removing old adhesive residue, drying the junction thoroughly, and applying mastic to the full joint perimeter with reinforcement mesh at stress points. We guarantee our mastic work for 90 days under our Done Right Promise, and we’ve seen our seals hold for decades in similar lakefront buildings.
