Call (844) 685-6342 for a free estimate with upfront pricing.
We’ve worked in Shively’s postwar neighborhoods for over four decades. We know the tight crawl spaces behind the ranch homes off Dixie Highway, the original sheet-metal ductwork in the Cape Cods near Saint Dennis, and the particular problems that come from living downwind of the Bernheim Distillery corridor. That local knowledge saves time and means we bring the right fix the first time.
Why Bellows Air Duct & Vent Co. Is Shively’s Preferred Duct Repair & Sealing Company
Shively homeowners call us because we’ve been here long enough to understand what their houses are built like. The 1940s-1960s housing stock in neighborhoods like Westlawn and near the old Kentucky Trailer plant wasn’t designed for modern HVAC loads, and the ductwork shows it. We’ve sealed and repaired ducts in hundreds of these homes. Our customers in 40216 know we’ll be there when we say, and they know the price we quote is the price on the invoice.
Our 90-Day Done Right Promise applies to every job in Shively. If the seal doesn’t hold, if a joint separates, if the problem returns, we come back at no charge. No paperwork to file, no argument. We’ve operated this way since 1984 because it’s the only way that keeps a local business running for 42 years.
Calls are answered by a live person 24 hours a day, not a voicemail tree. Our technicians are background-checked, uniformed, and equipped with camera inspection gear from Rotobrush and Abatement Technologies so you see the condition of your ducts before we start and the results after we finish. Most Shively repairs are completed in one visit.
Our Duct Repair & Sealing Services in Shively
Duct Sealing
Sealing is the most common service we perform in Shively, and for good reason. The original mastic on sheet-metal ducts in postwar homes near Fairdale Road and along Seventh Street Road has dried, cracked, or fallen away entirely after 60-70 years of thermal cycling. We seal these joints with fresh mastic sealant or metal-backed tape rated for HVAC use, then pressure-test the system to verify the seal. A typical duct sealing job in Shively runs $280-$480 for a single system, and the energy savings usually show up on the next bill.
Flex Duct Repair
Flex duct in Shively crawl spaces takes a beating. The high humidity from the Ohio Valley settles into unconditioned spaces, and the weight of sagging flex pulls connections loose at the plenum and register boots. In the West End near the Heaven Hill warehouses, we repaired a 1950s Cape Cod’s disconnected flex-duct in the crawl space, sealing joints with mastic and replacing a Honeywell filter grille caked with black fungal spores. The homeowner had mistakenly blamed soot for months. Flex duct repair in Shively typically costs $180-$340 per run, including reconnection, support, and sealing.
Metal Duct Repair
The galvanized steel ducts in Shively’s older homes corrode at seams and can separate entirely where supports have failed. We repair or replace sections, fabricate custom fittings where original parts are no longer available, and seal with mastic rated for metal-to-metal joints. Metal duct repair runs $320-$650 depending on accessibility and the extent of damage. Homes with ducts buried in slab or framed into tight soffits take longer, but we disclose that upfront before any cutting begins.
Duct Insulation
Uninsulated or poorly insulated ductwork in Shively crawl spaces and attics loses conditioned air to the outside and gains moisture in summer. We install foil-faced fiberglass insulation or closed-wrap duct insulation, sealed at all seams, to bring duct surfaces up to current energy code and reduce condensation. Duct insulation in Shively typically runs $4-$7 per linear foot, with most single-system homes falling in the $400-$800 range.

Trusted Brands We Service in Shively
We stock parts and materials from Aprilaire, Abatement Technologies, and Rotobrush on every Shively job, which means most repairs don’t wait on a parts run. Honeywell filter grilles, common in the area’s mid-century retrofits, are replaced same-day from our inventory. We don’t substitute off-brand materials to hit a price point. The equipment we carry is what serious HVAC contractors specify, and it’s what we install in our own Shively customers’ homes.
Common Duct Repair & Sealing Problems We See in Shively Homes
- Disconnected flex-duct in crawl spaces due to post-WWII construction settling. Shively’s slab-and-crawl-space homes shift seasonally on Kentucky clay soils, pulling flex duct away from plenum connections. The resulting leaks draw humid, unconditioned air directly into the system.
- Deteriorating mastic seals on original sheet-metal ducts. Common in 1940s-1960s homes throughout the Westlawn and Pleasantview neighborhoods, these failures cause conditioned air to bleed into walls and attics before reaching the rooms that need it.
- Baudoinia spore accumulation on HVAC intakes near distillery warehouses. Technicians working near the Heaven Hill warehouse cluster on the west side of Shively routinely find black sooty deposits at exterior HVAC intake grilles consistent with Baudoinia spore accumulation - a contamination source entirely absent in neighboring cities without distillery infrastructure and that homeowners often mistake for ordinary soot or mold.
- Elevated moisture in unconditioned crawl spaces accelerating mold and mildew growth. The Ohio Valley’s high summer humidity combined with Shively’s proximity to the distillery corridor creates ambient moisture levels that exceed what original duct materials were designed to handle.

FAQs - Duct Repair & Sealing in Shively
Yes, Baudoinia compniacensis spores from the distillery aging process are drawn into HVAC return vents throughout Shively, particularly in homes within a mile of the Heaven Hill warehouse cluster. The black accumulation on grilles and inside ducts is often mistaken for soot or ordinary mold, but it requires specific cleaning agents and improved filtration to address properly. If you’re seeing persistent black deposits near your intake vents in 40216, call (844) 685-6342 - we’ll inspect with a camera and show you exactly what’s in your system.
The original mastic and mechanical fasteners in postwar Shively homes have exceeded their design life by decades. Thermal expansion and contraction, combined with settling on Kentucky clay soils, cause joints to work loose. We remove the failed material, clean the mating surfaces, and apply fresh mastic sealant rated for 30+ years of service. Most resealing jobs in Shively’s Cape Cods and ranches hold permanently after proper repair.
Yes. Our technicians carry low-profile tools and flexible mastic applicators specifically for the confined crawl spaces common in Shively’s postwar construction. We’ve sealed ducts in spaces under 18 inches of clearance. We inspect first with a borescope camera so we know the layout before entering, which keeps the work efficient and the price predictable.
Soot is carbon residue from combustion sources like furnaces, candles, or nearby traffic, and it wipes away with standard cleaning. Whiskey fungus (Baudoinia compniacensis) is a living organism that etches into painted and metal surfaces, returns after ordinary cleaning, and carries a distinctive musty, fermented odor. In Shively, we see it concentrated on west-facing intakes near the distillery corridor. Proper identification matters because treatment differs. Call (844) 685-6342 for a camera inspection if you’re unsure what you’re seeing.
Yes, significantly. Leaky return ducts in unconditioned crawl spaces draw humid Ohio Valley air directly into your system, which the air conditioner then struggles to dehumidify. Sealing those leaks and insulating the ductwork reduces the moisture load. In Shively’s climate, properly sealed ducts often drop indoor humidity by 10-15% during peak summer months. We measure before and after with a hygrometer so you have the numbers.
