Why Bellows Air Duct & Vent Co. Is Broad Ripple’s Preferred Duct Repair & Sealing Company
We’ve worked in Broad Ripple long enough to know which crawl spaces are too tight for standard equipment and which plenums were jury-rigged from gravity-furnace cabinets in the 1970s. That matters when you’re deciding whether to seal what you have or start over.
Our Duct Repair & Sealing team has built a strong local reputation by showing up when we say and finishing in one visit. Homeowners here tell us they chose Bellows because the last company quoted a price that doubled once the truck arrived. We don’t work that way. Our no-hassle upfront pricing means the number we give you on the phone is the number on the invoice.
Calls are answered by a live person, 24 hours a day. Not a voicemail. Not an app. If you’ve got a duct leak blowing conditioned air into your crawl space on a Saturday night, someone picks up.
Every technician is background-checked and uniformed. Every job gets a camera inspection before and after, so you see what we see. And every repair is backed by our 90-Day Done Right Promise - in writing, no arguing, no paperwork to file.
Our Duct Repair & Sealing Services in Broad Ripple
Duct Sealing with Mastic Sealant
Standard foil tape fails on Broad Ripple’s older metal trunks. The temperature swings here - from below-zero January mornings to 90-degree July afternoons - expand and contract those joints until tape peels and adhesive turns to powder. We seal with professional-grade mastic, the same compound serious HVAC contractors specify for commercial jobs. On a typical 1920s bungalow near College Avenue, we’ll brush mastic into every joint and seam, then verify the seal with a pressure test. The result holds for years, not seasons.
Flex Duct Repair
Flexible duct sections were added to many Broad Ripple homes during piecemeal remodels, often run through tight crawl spaces with sharp bends that kink the inner liner. Near the White River corridor, that humid air accelerates the deterioration. We replace torn or collapsed flex runs with properly sized, insulated replacements - no more kinks, no more air loss into the joist bays. Most flex repairs in Broad Ripple run $180-$340 and finish in under two hours.
Metal Duct Repair
This is where Broad Ripple’s housing stock gets complicated. The craftsman bungalows and cape cods in the 46220 ZIP were built for gravity heat. When forced air came later, installers often cut the original furnace cabinet into a supply plenum and ran undersized trunk lines wherever they fit. Those oversized main trunks dead-end unpredictably. Joints leak. Pressure drops. We repair rusted sections, rehang sagging lines, and fabricate custom transitions where the original layout defeats standard fittings. It’s technical work. We’ve been doing it for over 42 years.
Duct Insulation
Uninsulated metal ducts in a Broad Ripple crawl space sweat all summer. That moisture drips onto joists, breeds mold, and destroys the mastic seals you just paid for. We wrap exposed trunks and plenums with vapor-barrier insulation rated for below-grade installation. On homes near the river, where ambient humidity runs higher than in Speedway or Fishers, this step isn’t optional. It’s what keeps your repair intact.

Trusted Brands We Service in Broad Ripple
We stock parts and materials from Rotobrush, Nikro, and Abatement Technologies - the brands that HVAC contractors specify when the job has to last. For mastic and sealants, we use Honeywell-grade compounds formulated for the temperature extremes of central Indiana. We don’t order special parts for Broad Ripple jobs. Our trucks carry them. That means faster turnaround and no return visits because something didn’t fit.
Common Duct Repair & Sealing Problems We See in Broad Ripple Homes
- Jury-rigged plenums from gravity furnaces create oversized trunks that leak air at every joint. We regularly measure 20-30% energy loss on these systems before sealing. The homeowner pays to heat their crawl space instead of their living room.
- Flexible duct sections added during multiple remodels are prone to kinks and tears, especially in tight crawl spaces near the White River’s humid corridor. Once the inner liner separates from the insulation, conditioned air escapes before it reaches the register.
- Original gravity-feed ducts left in place cause pressure imbalances when improperly sealed with standard tape. The result is condensation inside the trunk, then mold growth, then that musty smell every time the blower cycles on.
- Undersized retrofit trunk lines force the blower to work harder, increasing static pressure and shortening the furnace’s life. Sealing helps, but sometimes the right call is a partial redesign. We’ll tell you which it is before we quote.
Pricing for Duct Repair & Sealing in Broad Ripple, IN
| Service | Typical Range in Broad Ripple |
|---|---|
| Basic mastic sealing (single trunk, accessible) | $280-$420 |
| Flex duct repair/replacement (per run) | $180-$340 |
| Metal duct repair with custom fabrication | $350-$650 |
| Duct insulation (crawl space, per trunk) | $220-$480 |
| Full system assessment with camera inspection | $89 (credited toward repair) |
What moves you up or down within these ranges? Accessibility is the big one. A trunk line in a full basement costs less to seal than one threaded through a 24-inch crawl space under a bungalow near the Village core. The extent of damage matters too - a single leaking joint versus a plenum that needs complete reconfiguration. We assess with a camera before we quote, so you know exactly what you’re paying for. Call (844) 685-6342 for a free estimate. We also offer $50 off any repair over $250, and a free second opinion on any written estimate you’ve already received.

FAQs - Duct Repair & Sealing in Broad Ripple
Yes, in nearly every case we access and seal vintage ductwork through existing crawl spaces, basements, and utility closets without cutting into finished walls. On Broad Ripple bungalows, the original gravity-furnace plenum and trunk lines are typically exposed in the basement or crawl space, which gives us direct access to every joint. We cut small access ports at branch points where needed, seal with mastic, then close them with sealed panels. The work is invasive to the duct system, not to your living space. Call (844) 685-6342 to schedule a camera inspection - estimates are free.
Because it almost certainly is. The retrofit ductwork in 1920s-1950s Broad Ripple homes was often assembled with standard foil tape or no sealant at all, then subjected to decades of expansion and contraction from Indianapolis’s temperature swings. Joints open. Plenums crack where they were cut from original gravity-furnace cabinets. We measure the actual leakage with a pressure test, then seal every accessible joint with mastic rated for metal duct. Most homeowners see immediate improvement in airflow at the registers. Call for a free assessment.
Sealing will help significantly if the uneven heating is caused by air loss before the registers. In Broad Ripple craftsperson homes, we commonly find that 25-40% of heated air never reaches the rooms because it’s leaking into joist bays and crawl spaces. After proper mastic sealing, that conditioned air goes where it was intended. If the original trunk design is fundamentally unbalanced - oversized plenums that dead-end, or branches that were never properly sized - we may recommend partial duct modification alongside sealing. We’ll show you the camera footage and explain both options before you decide.
Usually, yes. The “one-piece” systems in mid-century Broad Ripple homes are typically sheet-metal trunk lines with welded or riveted seams that have developed pinholes or separated at expansion joints. We repair these with metal patches, mastic, and reinforcement tape designed for high-temperature applications. If the trunk is structurally sound - no widespread rust-through, no collapsed sections - repair is cost-effective and lasts for years. Replacement becomes necessary only when the metal itself has deteriorated. We’ll give you an honest assessment either way. Our $89 Seasonal Tune-Up includes a full duct inspection if you’re unsure what you’re dealing with.
Broad Ripple’s proximity to the White River corridor means higher ambient humidity than neighborhoods further from the floodplain, especially in summer. That moisture accelerates the breakdown of standard duct tape and promotes mold growth on uninsulated metal surfaces. We counter this by using mastic compounds formulated for damp environments and by insulating every sealed trunk that runs through a crawl space. A properly sealed and insulated system in Broad Ripple should maintain its integrity for 10-15 years, versus 2-3 years for tape-only repairs. The upfront difference in materials pays for itself quickly. Call (844) 685-6342 to discuss what your home needs.
