AfterHow Much Does Duct Repair & Sealing Cost in New Orleans?
Duct repair and sealing in New Orleans typically runs $350 to $900 for a focused repair on a single trunk line or a handful of disconnected joints, and $1,200 to $2,800 when a whole system needs re-sealing, re-hanging, or partial replacement of damaged runs. A full duct replacement on an older home with long attic runs generally lands between $3,500 and $6,500. The written estimate sets the final price, and every estimate we give is free.
That range is wide because ductwork here is genuinely varied. New Orleans homes are a mix of raised cottages, camelbacks, and slab-on-grade ranches, and the duct systems in them were installed across roughly seven decades of building. Some are flex duct in a low attic. Some are sheet metal in a soffit chase. Some are older ductboard that has softened over time. Each one prices differently because each one repairs differently.
Our technicians have up to 14 years of experience with residential and commercial ductwork, and we do this work as a specialty rather than as an add-on to general HVAC service. That matters for pricing: a crew that fixes what it finds on site avoids the second appointment, the second trip charge, and the second estimate that comes with a company that can only report a breach and refer you onward.
Key Takeaways
- Typical single-point duct repair in New Orleans: $350 – $900.
- Whole-system sealing and re-connection: $1,200 – $2,800.
- Partial or full duct replacement: $3,500 – $6,500.
- Estimates are free and the written estimate sets the final price.
- Attic heat and humidity here accelerate duct deterioration, so problems rarely fix themselves.
Duct Repair & Sealing Cost Breakdown (2026)
The table below reflects typical New Orleans market ranges for the work itself. These are estimates, not quotes. What we find when we open up the system can move the number up or down, and we tell you why before any work starts.
| Line Item | Typical Range (New Orleans, 2026) |
|---|---|
| Single disconnected joint or boot reconnection | $150 – $350 |
| Breach or tear repair on flex duct (per run) | $200 – $450 |
| Sealing accessible joints and plenums (partial system) | $400 – $850 |
| Whole-system sealing and re-connection | $1,200 – $2,800 |
| Re-hanging and re-supporting sagging duct runs | $300 – $700 |
| Replacing a damaged run of flex duct | $350 – $800 per run |
| Sheet metal trunk repair or section replacement | $600 – $1,600 |
| Ductboard section replacement | $450 – $1,100 |
| Full duct replacement (larger or multi-run systems) | $3,500 – $6,500+ |
| Duct cleaning combined with repair (same visit) | Cleaning range plus repair scope |
What pushes a job toward the top of these bands? Attic access, for one. A duct system that runs through a cramped low-slope attic takes more time to reach and work in than one in a wide, walkable space, and labor is the largest single cost in any duct job. System size matters too: a small single-story home may have six or seven supply runs, while a larger two-story property can carry twenty or more. Material choice moves the number as well. Flex duct is generally the least expensive to replace, sheet metal the most durable and the most labor-intensive, and ductboard sits in the middle. And existing condition is often the wild card. A system with a handful of failed connections is a straightforward job; one with crushed runs, pest damage, moisture-damaged ductboard, or improper transitions from earlier patch work can require more replacement than repair.
Where a job lands closer to the bottom of the band: accessible joints, a single obvious breach, or a system that’s otherwise sound and just needs sealing and re-supporting. We combine rotary brush agitation with HEPA-rated vacuum capture on every cleaning, so if you’re having repair and cleaning handled together, the cleaning doesn’t have to be repeated later once the breach is closed.
What Affects Duct Repair & Sealing Pricing in New Orleans
Six factors drive most of the price difference on a New Orleans duct job. Understanding them before you get an estimate helps you compare bids on the same footing instead of comparing a low number against a complete scope.
- Attic conditions and access. New Orleans attics are hot, tight, and often packed with insulation or mechanical equipment. Longer attic runs, low clearances, and limited pathways all mean more labor per repair. The city’s long hot season also means ductwork spends most of the year under thermal stress, which is part of why joints fail rather than holding for decades.
- Duct type and age of construction. A raised cottage in the Garden District may have original chases or later retrofits, while a Mid-City camelback often has a mix of construction eras layered into one system. Flex, sheet metal, and ductboard all price differently to repair and replace.
- Humidity and moisture history. Ductboard that’s been damp loses structural integrity, and damp duct interiors are a common source of musty odors. When ductboard has softened, we usually replace that section rather than patch it, since a patch won’t hold. That changes a repair into a replacement on part of the run.
- Number of breaches and previous patch work. One disconnected boot is a quick fix. Ten is a system-level problem. Earlier foil-tape patches that have dried out and let go often need to be stripped and redone properly, which adds time.
- Whether cleaning is part of the same visit. Sealing a duct system without addressing what’s inside it is a half job. Since we run Rotobrush rotary brush systems and Nikro HEPA vacuums on our cleaning work, combining repair and cleaning in one appointment usually costs less than booking them separately.
- Filtration upgrades you may want at the same time. If you’re already opening the system, adding a better filter setup makes sense. We’re authorized to supply and install Honeywell and Aprilaire whole-home air quality products, so it’s one visit instead of two contractors.
Why Duct Repair Often Costs Less Than Replacing the System
Most of the duct problems we find in New Orleans homes are fixable without touching the entire system. A disconnected boot at a supply register, a sagging flex run, a collapsed takeoff, or a plenum with failing seams: these are targeted repairs. The reason it pays to fix them promptly is that leaks don’t just waste conditioned air. They let in attic air, insulation fibers, and whatever else is in that space, and they throw off the pressure balance across the whole system, which makes the equipment work harder in every room.
A representative job on a mid-sized New Orleans home in the $1,200 to $2,800 band typically includes a full inspection of accessible runs, sealing of accessible joints and plenums, re-supporting sagging sections, and reconnecting any boots that have separated from the floor or wall register. That kind of scope addresses the majority of comfort complaints we hear: rooms that never get comfortable, dust returning days after cleaning, and musty smells when the system first kicks on.
When the system has gone further than that, partial replacement of the worst runs is often the practical answer. Full replacement is the option when the ductboard has degraded across multiple sections or the original layout doesn’t fit the current equipment. We’ll tell you which category your system fits and why, and you can decide from there. If you’d like the broader picture of what duct services cost across the metro, see our New Orleans Duct Cleaning guide, which covers cleaning, dryer vent work, and repair together.
How to Save on Duct Repair & Sealing
There’s no magic to bringing a duct repair estimate down. Most savings come from doing a few things in the right order.
- Get the estimate before the work, in writing. A written scope that names what’s being repaired, how many runs are involved, and whether replacement is included is the single biggest protection you have. Estimates from us are free.
- Address repair and cleaning together. Opening up a duct system twice for two separate services adds labor you don’t need to pay twice. If both are needed, book them together.
- Fix small breaches before they cascade. A loose boot fixed at the $150 to $350 end of the scale is a fraction of what the same leak costs once it’s soaked nearby ductboard or disrupted pressure balance for a season.
- Ask what’s repairable and what isn’t. Some contractors quote full replacement when a partial one will do. Ask specifically which runs are compromised and why. A good answer should be about condition, not convenience.
- Consider filtration in the same visit. If you’re thinking about a Honeywell or Aprilaire upgrade, doing it when the system is already apart saves the cost of opening it up again.
- Have the dryer vent checked to spec. Dryer vent cleaning is a separate service, but it’s a genuine safety issue when lint builds up. If we’re already doing ductwork, it’s often handled in a single appointment. So is a Guardsman-graded protective treatment for lasting results.

Duct Repair vs. Duct Replacement: Which Costs More Over Time?
Repair costs less up front in nearly every case. Replacement can cost less over a decade if the duct system is broadly degraded, because patching a system in that condition usually means repairing it again soon. The line between the two comes down to how much of the ductwork is still structurally sound. Ductboard that’s been damp through a hot, humid summer can lose rigidity across an entire run. Flex duct with a pattern of multiple breaches is often cheaper to replace run by run than to keep patching. Sheet metal with failing seams or a single damaged section is usually repairable and worth keeping.
We assess each run individually rather than giving you a system-wide yes or no. That’s part of what it means to repair what others only report: we can close the breach during the visit instead of writing it up as a finding for someone else to quote.
What’s Included in a Duct Repair and Sealing Visit
Our scope on a repair and sealing job generally covers inspection of all accessible duct runs, identification of breaches, disconnects, collapsed sections, and poorly sealed joints, reconnection of separated boots and takeoffs, sealing of accessible joints and plenums with appropriate materials, re-supporting of sagging sections, and a written summary of what was repaired and what was found beyond repair. Where we’ve done cleaning as part of the same visit, we run rotary brush agitation followed by Nikro HEPA capture, and use Abatement Technologies filtration equipment to keep the workspace clean.
What’s Not Included (and Why We Say So Upfront)
We specialize in ductwork and indoor air quality. We don’t install HVAC equipment, service refrigerant systems, or replace furnaces or air handlers. If we find a problem in the mechanical equipment itself during the inspection, we’ll tell you, and you’ll need a licensed HVAC contractor for that portion of the work. We’d rather say so clearly than have you find out halfway through the job.
Frequently Asked Questions About Duct Repair & Sealing Costs
How much does duct repair cost in New Orleans?
A focused repair on one connection or a small number of breaches typically runs $150 to $900. Whole-system sealing is $1,200 to $2,800. Partial or full duct replacement is $3,500 to $6,500. Call (833) 749-5104 for an exact quote; estimates are free and the written estimate sets the final price.
Is it cheaper to repair or replace ductwork in New Orleans?
Repair is cheaper up front in most cases. Replacement makes more economic sense when ductboard has softened across several runs, when flex duct has repeated breaches, or when the system has more damage than good material. A targeted repair in the $200 to $800 range is usually possible when only one or two runs are compromised. Call (833) 749-5104 and we’ll tell you which category your system fits.
How much does duct sealing alone cost?
Sealing accessible joints and plenums on a partial system typically runs $400 to $850. Whole-system sealing is $1,200 to $2,800. If you combine sealing with duct cleaning in one visit, you save the cost of a second setup. Call (833) 749-5104 to schedule an estimate.
Do I need a permit for duct repair in New Orleans?
Most ductwork repairs and reconnections don’t require a permit, but duct replacement or a substantial change to the system layout may. Permit rules vary by project, so check with the city’s building department before any larger job. We can talk through what your scope likely requires when we’re on site. Call (833) 749-5104.
Can you come today?
Same-day service is often possible. We answer 24/7, with fast dispatch from 7am to 7pm, Sunday through Friday, and we’re closed Saturday. A call outside dispatch hours is booked into the next opening, Sunday through Friday, 7am to 7pm. Call (833) 749-5104 to check availability.

Contact Us for a Duct Repair & Sealing Estimate
Duct problems get worse in a New Orleans summer, not better. A breach that’s pulling in hot, humid attic air doesn’t just cost you money on every cooling bill; it also lets moisture into the system, and moisture is what turns a small repair into a replacement six months later. We’ve seen enough of that to know it’s avoidable.
If you’d like a written estimate for duct repair and sealing, call (833) 749-5104. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
