AfterHow Much Does Duct Repair & Sealing Cost in Aurora?
Duct repair and sealing in Aurora typically costs between $300 and $1,400 for most homes, with minor joint sealing around $300 – $550 and larger repairs to disconnected runs, crushed flex duct, or plenum transitions landing at $700 – $1,400. Whole-home sealing of a heavily leaky system often runs $600 – $1,100. The written estimate sets the final price, and the estimate itself is free.
What most homeowners don’t realize is that the number moves with the layout of the house, not just the size of the leak. A ranch with a crawlspace in Aurora is a very different job from a two-story with a basement and finished attic, and pricing reflects that. Below we break down the 2026 ranges line by line.
Duct Repair & Sealing Cost Breakdown (2026)
These are typical estimated ranges for the Aurora market. Your written estimate will be specific to your home.
| Work item | Typical estimated range |
|---|---|
| Sealing accessible joints, seams, and boot connections | $300 – $550 |
| Sealing the full trunk line and plenum | $450 – $800 |
| Reconnecting a disconnected run or boot | $250 – $500 |
| Replacing crushed or collapsed flex duct (per run) | $200 – $450 |
| Repairing a damaged plenum or trunk transition | $500 – $1,100 |
| Whole-home sealing of a leaky system | $600 – $1,100 |
| Duct repair combined with a full cleaning visit | $700 – $1,400 |
| Mastic and mesh repair of rodent-damaged sections | $350 – $700 |
The single biggest driver of price is access. A joint you can reach from a basement ceiling takes minutes to seal; the same joint hidden behind drywall or packed under attic insulation takes far longer. Older homes in Aurora’s near-downtown neighborhoods often have octopus-style ductwork with dozens of short runs and a lot of connections, which is more surface area to seal than a modern home with a straight trunk and few branches. Duct material matters too. Sheet metal sealing holds up well, while deteriorating flex duct sometimes needs replacement rather than sealing, and that shifts the job from a sealing price to a repair price. If the cleaning visit turns up a leak, we fix it during the same relationship so you’re not calling a second contractor.
What Affects Duct Repair & Sealing Pricing in Aurora
- Access to the ductwork. A basement or crawlspace with open trunk lines lets us reach most connections; a home with closed soffits or ducts buried in attic insulation adds time and labor. It’s the most common reason an estimate comes back higher than expected.
- How much of the system is leaking. A handful of loose joints at the supply boots is a modest job. A trunk line that’s pulling apart at the seams in multiple spots, or a system with a dozen or more disconnected connections, is a larger sealing project.
- Duct material and condition. Sheet metal and rigid duct can usually be sealed. Flex duct that has collapsed, torn, or been crushed by storage is a replacement job, and that changes the line item.
- Age of the home and the duct layout. Aurora has a wide mix of housing stock, and older layouts with many short runs and bends have more joints to seal than a modern straight-run design. We count the actual connections rather than quoting by square footage.
- Whether you combine repair with cleaning. Sealing a duct system that’s still full of dust and debris isn’t money well spent. Bundling a cleaning visit with the repair means the system is clean before it’s sealed, and it usually costs less than two separate visits.
- What we find behind the vents. Post-renovation debris, rodent damage, or signs of moisture sometimes show up during inspection. If the job calls for higher-contamination handling, the equipment and time change, and so does the price.
We don’t just clean – we inspect and repair. That means if we open a boot and find a disconnected run behind it, we can fix it on the spot rather than flagging it and asking you to book someone else.
How to Save on Duct Repair & Sealing
There’s no coupon that fixes a crushed duct run. The savings come from doing the right work once rather than in pieces.
- Get the repair done during a cleaning visit. Combining the two means one trip, one inspection, and one estimate that covers both. It’s the most reliable way to keep the total down.
- Fix the leaks you have before adding more. If you’re planning to finish a basement or add a room, seal the existing system first. Sealing a leaky trunk now costs less than sealing it after new drywall goes up.
- Don’t seal before cleaning. Sealing a dirty system traps dust inside and defeats the point. Clean, then seal, in that order.
- Keep an eye on flex duct runs in the attic and crawlspace. Loose, crushed, or torn flex is common and cheap to repair when it’s caught early. Left alone, it can pull completely free and cost more to reconnect.
- Ask for a written estimate with line items. You should know what each repair costs before anyone touches your ductwork. The estimate is free, and the written estimate is what sets the final price.
Call (888) 364-6081. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday. Estimates are free, and we’ll tell you exactly what’s leaking and what it costs to seal it.
How Long Does Duct Sealing Take in Aurora?
Most duct sealing jobs in Aurora take half a day, roughly three to five hours. A full repair that involves reconnecting runs or replacing crushed flex can stretch to a full day, especially in a home with many short branches and tight attic access. Combing repair with cleaning usually fits in one visit.

Why Aurora Ductwork Fails in the First Place
Duct systems fail quietly. The connections at the supply boots, the seams along the trunk line, and the transition at the plenum are all points that loosen over time as the system heats and cools through Illinois’ seasonal swings. Aurora winters are cold enough that the furnace runs hard for months, and the constant expansion and contraction works joints loose. Summer cooling adds its own cycling. The result is a system that slowly leaks a meaningful share of the air it moves.
Flex duct brings its own issues. It runs through attics and crawlspaces where it’s easy to crush with storage, pinch at a sharp bend, or tear on a nail or staple. Rodents find it too, especially in older crawlspaces. None of this shows up on a thermostat. It shows up as rooms that never quite get comfortable and a utility bill that creeps up.
That’s why we inspect before we seal. The Aurora Duct Cleaning team uses professional-grade equipment from Rotobrush and Nikro to see inside the system, and we carry Abatement Technologies filtration capability for higher-contamination environments like post-renovation ductwork. Cleaner air starts behind the vents, and it starts with knowing what’s actually there.
What’s the Difference Between Duct Repair and Duct Sealing?
Duct sealing closes the gaps that are already there but haven’t failed. Duct repair fixes the parts that have actually broken: a run that’s disconnected, flex that’s collapsed, a plenum seam that’s pulled apart. Most homes need some of both, and we quote them together.
Sealing is typically the less expensive of the two because it’s labor, not material. Repair involves cutting out and replacing failed sections, which is why the line items differ. See our full breakdown of air duct repair for the repair side of the work, and air duct cleaning for the cleaning visit that usually precedes it. If you’re in one of Aurora’s surrounding communities, we also serve Naperville, Oswego, North Aurora, Batavia, and Geneva – the pricing ranges on this page apply across the area.
One thing we won’t do is seal a duct system that hasn’t been inspected. Sealing over a disconnected run just traps the leak behind the mastic.
When Should You Seal Rather Than Replace?
Seal when the ductwork is structurally sound and the leaks are at joints, seams, and connections. Replace when the duct material itself has failed, like crushed flex or a trunk line that’s rusted through. Sealing is the lower-cost option in the first case; in the second, sealing a failing duct won’t hold.
A technician with up to experience can usually tell you which situation you’re in within the first inspection. Call (888) 364-6081 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Duct Sealing and Your Indoor Air Quality Equipment
Many Aurora homes have a whole-home humidifier, air cleaner, or ventilation system tied into the ductwork. Sealing leaks around that equipment matters, because a leaking connection near a Honeywell or Aprilaire unit undercuts the work the equipment is doing. We’re familiar with how those systems connect to the ducts, so the sealing work doesn’t interfere with them.
If you’re not sure what’s connected to your system, the inspection will clarify it. We also clean dryer vents, which is a separate safety issue worth mentioning if you’re booking a visit – lint-clogged dryer vents are a documented fire risk, and they’re a good reason to have the whole system looked at. Our dryer vent cleaning page covers it.
What Happens When You Call
We start with a conversation about what you’re noticing: rooms that don’t heat evenly, a whistling sound at a vent, a utility bill that’s crept up, dust in the air. Then we schedule a visit and inspect the system. You get a written estimate with line items before any work begins. The estimate is free, and the written estimate sets the final price.
We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday. We’re closed on Saturday.
If a call comes in outside dispatch hours, we’ll book it into the next opening, Sunday through Friday, 7am to 7pm. Same-day service is often possible when you call early.
FAQs – Duct Repair & Sealing Cost
How much does duct repair cost in Aurora?
Duct repair in Aurora typically costs $250 – $1,100 depending on what’s broken. Reconnecting a disconnected run runs $250 – $500, replacing crushed flex is $200 – $450 per run, and repairing a damaged plenum or trunk transition runs $500 – $1,100. Call (888) 364-6081 for an exact quote – estimates are free.
How much does duct sealing cost in Aurora?
Duct sealing in Aurora typically costs $300 – $1,100. Sealing accessible joints and boot connections runs $300 – $550; sealing the full trunk line and plenum is $450 – $800; and a whole-home sealing of a leaky system is $600 – $1,100. Call (888) 364-6081 to schedule a free estimate.
Is duct sealing worth the money?
Yes, when the ducts are clean and the leaks are real. Sealing closes gaps that let conditioned air escape, and in most Aurora homes the cost is recovered over time through a system that doesn’t have to work as hard. It’s not worth it if the ductwork is already failing – then repair or replacement comes first. Call (888) 364-6081 for a free estimate.
Can you repair and seal ducts in one visit?
Yes, in most cases. Combining repair and sealing with a cleaning visit usually fits in a half-day to full-day window. The pricing for a combined visit typically runs $700 – $1,400, which is less than scheduling two separate appointments. Call (888) 364-6081. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
How do I know if my ducts need sealing?
Common signs include rooms that don’t heat or cool evenly, whistling at the vents, and a utility bill that has crept up without a change in use. An inspection confirms it, and the ranges above tell you what the work typically costs. Call (888) 364-6081 for a free estimate – we’ll tell you what we find.
Do you seal ductwork behind finished walls?
Where the connection is accessible, yes – through an existing opening or a boot. When a joint is sealed behind finished drywall with no access, we’ll tell you what can be reached and what can’t, and the estimate reflects it. Call (888) 364-6081 with questions about your specific layout.

"My wife's allergies had been bad in this house since we moved in. It's been two months since they did the ducts and it's noticeably better. Not a miracle, but real."
- Mark Vaughn"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
- Ryan Meyer"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
- Yolanda Coleman
