AfterHow Much Does Duct Repair & Sealing Cost in Greeley?
Duct repair and sealing in Greeley typically costs $250 to $1,800, with most single-system repairs landing between $350 and $750. Small fixes like resealing a few leaking joints run $250 to $450, while reconnecting a collapsed trunk line or replacing a length of damaged flex duct pushes toward $900 to $1,800. If you want the exact number for your house, that comes from a free written estimate after a technician inspects the system.
We answer (833) 467-7154 around the clock, and fast dispatch runs from 7am to 7pm, Sunday through Friday. Estimates are free, and the price you’re quoted in writing is the price you pay for the job.
Key Takeaways
- Most Greeley duct repairs fall between $350 and $750; bigger jobs with full reconnection or replacement reach $1,800.
- Air sealing alone is usually the cheapest line item and often the highest-value fix, since leaky joints in unconditioned space waste conditioned air year-round.
- Repair and cleaning are different services. We do both in one visit: we clean it, and if we find damage, we repair it, same visit, same team.
- Our technicians have up to 12 years of experience with Rotobrush and Nikro professional-grade systems, not repurposed consumer tools.
- Estimates are free. The written estimate sets the final price.
Duct Repair & Sealing Cost Breakdown (2026)
These are typical estimated ranges for the Greeley market in 2026. Every home is different, so treat each figure as a starting point and let the written estimate set the final price.
| Job | Typical Estimated Range | What’s Involved |
|---|---|---|
| Air sealing of accessible joints and seams | $250 – $450 | Mastic or foil-tape sealing at boot connections, plenum seams, and register boxes |
| Resealing the full supply-and-return network | $450 – $850 | Sealing throughout the accessible system, plus confirming register airflow after |
| Reconnecting a disconnected duct run | $300 – $600 per run | Reline, reconnect, and secure a run that’s pulled loose in the attic or crawlspace |
| Replacing a section of damaged rigid or flex duct | $450 – $900 | Cut out crushed or torn duct, fit new duct, seal and support it properly |
| Replacing a collapsed trunk line | $900 – $1,800 | Rebuild a main trunk that’s caved in or separated, with new transitions and takeoffs |
| Register and boot repair | $150 – $350 per register | Fix a sagging or detached boot, replace a crushed takeoff, reseal the register opening |
| Cleaning before or after repair | $350 – $700 | Rotobrush rotary brush and Nikro HEPA vacuum work; often done the same visit as repair |
What pushes a Greeley duct repair toward the top of the range?
Two things usually drive cost up: how hard it is to reach the damaged section, and how many runs are affected. A single loose boot under a first-floor register is a quick fix. A trunk line that’s separated in the attic above a vaulted ceiling takes longer to access, support, and seal correctly. If the system has multiple disconnected runs, each one adds labor and materials, so a job that starts at $300 for one connection can climb when the inspection turns up four. That’s why we look at the whole system before quoting, not just the spot you noticed.
Cleaning and repair are separate line items, and each one is priced on its own. When we find damage during a cleaning, we tell you before anything changes and quote the repair as a written add-on. You decide whether we handle it the same visit or later.
What Affects Duct Repair & Sealing Pricing in Greeley
Greeley’s climate and housing stock both shape what a duct job actually costs here. These are the factors we weigh during an inspection:
- Attic and crawlspace conditions. Older Greeley homes in neighborhoods like Glenmere and the older blocks near downtown often have ductwork routed through unconditioned attic space, where summer heat and winter cold both stress the duct, its insulation, and its connections. Duct up there takes more abuse than duct run inside a conditioned chase, so repairs tend to be more involved.
- The dry air and dust. Northern Colorado’s low humidity and dusty spring winds mean seams and taped joints dry out, crack, and pull apart sooner than they would in a humid climate. That silent degradation is often the reason a homeowner first notices a room that won’t heat or cool the way it used to.
- Accessibility. A duct run over open attic floor is straightforward. One buried under blown insulation, packed behind a knee wall, or routed above a finished ceiling adds time and care to every step.
- Duct type and condition. Flex duct that’s crushed or kinked at a sharp turn is common and inexpensive to correct. Rigid sheet-metal trunk that’s separated at a joint is heavier work, and rebuilding a collapsed trunk costs more than patching a torn run.
- Number of problem areas. Sealing one plenum is cheap. Resealing an entire supply-and-return network, then reconnecting two dropped runs, adds up. The more of the system is compromised, the further the job moves toward the top of the range.
- Whether cleaning is needed first. Repair work on a duct system that hasn’t been cleaned in years is often easier and more accurate after the debris is removed, since we can see the actual condition of the duct surface and every joint. We quote cleaning and repair together when that makes sense for the job.
You’ll find more on how we handle the cleaning half of a visit on our duct cleaning Greeley page, and a wider look at the area we serve sits on our Greeley hub.
How Does Duct Sealing Actually Work?
Sealing is the most under-appreciated way to spend money on a duct system. The principle is simple: every joint, seam, boot, and register connection is a potential leak, and leaks in unconditioned space waste the conditioned air you paid to heat or cool. A technician works through the accessible system and closes those gaps with mastic, foil-backed tape rated for ductwork, or mechanical fasteners where a joint needs to hold. It’s methodical, unglamorous work, and it’s often what makes a room feel comfortable for the first time.
It also has to be done right. Standard cloth-backed “duct tape” dries out and fails, which is the opposite of what you want. Proper duct mastic, applied to a clean surface, is the material that lasts. When we seal a system, we also check that registers still deliver the airflow they should afterward, because sealing a run that was already starved of air doesn’t help anyone.
What Does Duct Repair Involve?
Repair is where a cleaning-only operation usually stops and hands you off to someone else. We don’t. Our technicians handle Air Duct Repair in-house, so when a cleaning uncovers a disconnected run, a torn length of flex, or a crushed boot, we can fix it on the same visit.
Before we touch anything, we inspect. We run professional-grade equipment through the system, and we look inside it with the same care we’d want used in our own homes. Common findings in Greeley homes include:
- Flex duct pulled loose at a register boot, so conditioned air dumps into the attic instead of into the room
- Torn or crushed flex where a run has been stepped on or pinched against a joist
- Separated joints at a sheet-metal trunk, often at a takeoff or transition
- Boots that have sagged away from the drywall opening, leaving a gap around the register
- Old tape failing at seams throughout an accessible system
Once we’ve found the problem, we quote it in writing and get your go-ahead before work starts. Then we repair, reseal, and confirm the fix. We contain what we dislodge along the way; Abatement Technologies air-filtration equipment runs on every job, so debris doesn’t get redistributed through the house while we work.
Why equipment matters on repair and sealing jobs
The same professional-grade equipment that makes cleaning effective makes repair accurate. Rotobrush rotary brush systems give us thorough mechanical agitation and extraction of the duct surfaces, and Nikro HEPA-rated vacuums capture particulate at a level consumer tools can’t touch. When we seal or reconnect a run, we do it on a clean surface, which is the only way the seal holds. Budget operators with a shop vac and a hose can’t give you that, and repair work done on a dirty, unseen surface often fails early.
How to Save on Duct Repair & Sealing
There’s no trick to spending less on this work. There are a few sensible steps that keep the scope honest and the price down.
- Get the estimate in writing before work starts. A written estimate is free and it’s the number that counts. Ask what’s included: sealing, materials, cleanup, and whether a post-repair airflow check is part of the job. Ours are free, and we walk you through line by line.
- Fix the source before you reseal. If a run came loose because a boot wasn’t supported or a joist squeezed it, resealing it alone won’t last. Ask the technician to identify why it failed, not just patch the failure. That small step saves a repeat visit later.
- Bundle cleaning and repair when both are needed. If the system hasn’t been cleaned in years, cleaning first lets the technician see the full extent of the damage. Doing both in one visit usually costs less than two separate appointments, and it prevents the awkward surprise of discovering more damage right after the first job.
- Ask about the whole system, not just the noisy room. A single room that won’t heat may be one loose run. But if other rooms feel weak too, it’s worth having the accessible system sealed once rather than fixing one leak at a time over several years.
- Keep your filters and air-quality equipment working as designed. If you’ve invested in a Honeywell or Aprilaire filtration system, mention it before the visit. Our technicians work with those brands and know how to protect what’s already in place rather than working around it.

Is It Cheaper to Repair or Replace a Duct System?
Repair is almost always cheaper in Greeley, and it’s the right first step in most cases. A reseal runs $250 to $850, while reconnecting a dropped run typically costs $300 to $600. Replacing a full duct system is a much larger project that usually comes into play only when the ducting has failed across the board, the system was never sized properly for the home, or the layout needs to change. In most houses, that’s not the case, and targeted repair and sealing solve the problem at a fraction of the cost.
That said, we’re honest about what we find. If the damage is extensive enough that replacement is the better long-term choice, we’ll tell you and explain why, so you can make the call with the facts. Call (833) 467-7154 for a free estimate and we’ll help you figure out which way makes sense.
Can Duct Repair Be Done the Same Day?
Yes, in many cases. If the damage is accessible and the repair is straightforward, like resealing a disconnected run or replacing a short length of damaged flex, we can often handle it during the same visit as the inspection or cleaning. More involved jobs, especially a collapsed trunk line or damage under blown insulation, may need a scheduled follow-up so we can bring the right materials and give it proper time. We’ll tell you at the estimate which bucket your job falls into, and the price is set per job by the written estimate. Call (833) 467-7154 to get on the schedule.
Does Leaky Ductwork Change Your Energy Bill in Greeley?
Yes, and it’s often the most overlooked reason homeowners call us. When ducts leak in an unconditioned attic or crawlspace, the heated or cooled air your system produced escapes before it reaches the room. The result is a room that’s slow to reach temperature, a system that runs longer, and higher utility bills, especially during Greeley’s hot summers and cold snaps. Sealing those leaks is a low-cost fix with a real effect on comfort and energy use.
We don’t quote specific savings, because every home is different. What we can do is seal the leaks correctly and confirm the system is delivering the airflow it should after. That’s the honest version of what sealing does.
FAQs – Duct Repair & Sealing Cost
How much does duct repair cost in Greeley?
Duct repair in Greeley typically costs $250 to $1,800, with most jobs in the $350 to $750 range. Small resealing jobs start around $250 to $450, single-run reconnections run $300 to $600, and rebuilding a collapsed trunk line reaches $900 to $1,800. The written estimate sets the final price, and estimates are free. Call (833) 467-7154 to get an exact quote.
How much does duct sealing cost compared with cleaning?
Sealing typically runs $250 to $850 depending on how much of the accessible system needs to be sealed, while air duct cleaning usually runs $350 to $700. They cover different work: cleaning removes debris from the duct surfaces, and sealing closes the leaks. If a system needs both, doing them in one visit usually costs less than two separate appointments. Call (833) 467-7154 for a free estimate that covers both.
Is it cheaper to repair a duct or replace it?
Repair is almost always cheaper. A reseal at $250 to $850, or a run reconnection at $300 to $600, costs a small fraction of replacing a full duct system. Replacement typically comes up only when the ducting has failed across the whole system or was never sized properly for the home. An inspection tells you which situation you’re in. Call (833) 467-7154 for a free estimate.
Can you find and fix duct damage during a cleaning?
Yes. Cleaning is often when damage gets found, because getting eyes on the interior of the system reveals disconnections, tears, and crushed runs that are invisible from the outside. Our technicians do both cleaning and repair in-house, so if we find a problem during the cleaning, we can repair it the same visit. Call (833) 467-7154 for a free estimate.
Do leaky ducts in Greeley really raise energy bills?
Yes. Leaks in ductwork routed through unconditioned attic or crawlspace space let heated or cooled air escape before it reaches the room, so the system runs longer to hit the thermostat setting. Sealing those leaks usually helps comfort and energy use. Exact savings vary by home, so we repair and reseal properly and check airflow afterward rather than quote a number we can’t verify. Call (833) 467-7154 for a free estimate.
What equipment do you use on a duct repair or sealing job?
We use Rotobrush rotary brush systems and Nikro HEPA-rated vacuums on every job, with Abatement Technologies air-filtration equipment running to maintain negative pressure and contain what we dislodge. That equipment lets us repair and reseal ductwork on a clean surface, which is the only way the work lasts. Our technicians have up to 12 years of experience with these systems. Call (833) 467-7154 for a free estimate.
What Else Should You Know Before Booking?
Before any duct repair or sealing visit, it helps to know what you’re walking into. Here’s what a typical visit involves. We inspect the accessible system with the equipment above, and we look for the sources of the problem, not just the symptoms. We give you a written estimate before any work begins. We contain the debris we dislodge so it doesn’t wind up back in your living space. And we finish by confirming the system is moving the air it should through every register.
Safety matters here too. Ductwork runs alongside wiring and gas appliances in many Greeley homes, and a careless repair can damage the very components you rely on for safety. If wiring or a gas connection is part of the problem, that’s a job for a trained specialist, and we’ll flag it so you can get the right person. We handle the duct repair work and stop where that work stops.
If your existing filtration system uses Honeywell or Aprilaire components, we’re familiar with those brands and will work around them rather than disturb them. Same for Guardsman-compatible components. If your dryer vent came up during the inspection, we also handle dryer vent cleaning as a dedicated service, which addresses a documented fire hazard in its own right.
