AfterHow Much Does Duct Repair & Sealing Cost in Metairie?
Duct repair and sealing in Metairie typically costs between $350 and $1,400 for most homes, with the average landing around $650. Small fixes like sealing a few joints or reconnecting one flex run run $350 to $600. Larger jobs that involve replacing sections of damaged ductwork, sealing an entire attic system, or correcting a design problem climb to $1,400 and beyond. The written estimate sets the final price, and it’s free.
That range covers the two things that actually go wrong with ductwork: leaks and physical damage. Leaky joints quietly waste the cooled air you’re paying for. Disconnected or crushed sections blow conditioned air into the attic instead of your rooms. Both are fixable, and both change what your electric bill looks like in a Metairie summer.
We run professional-grade equipment on every job: Rotobrush rotary brushes for mechanical agitation, Nikro vacuum systems for extraction, and Abatement Technologies filtration units to keep dust contained while we work. You’ll get a clear explanation of what’s wrong before anyone touches a joint, and a written estimate before any work starts.
Key Takeaways
- Most Metairie duct repair and sealing jobs land between $350 and $1,400.
- Sealing accessible joints in an attic or crawlspace is the lowest-cost fix.
- Replacing damaged flex duct, plenum sections, or trunk line runs pushes cost higher.
- Free estimates and upfront written pricing. Call (833) 576-1083.
- Our technicians have up to 9 years of experience diagnosing duct system problems.
Duct Repair & Sealing Cost Breakdown (2026)
Here’s what the individual pieces of a duct repair and sealing job tend to cost in the Metairie market. These are typical ranges, not quotes. A written estimate after we inspect your system will give you the real number.
| Service | Typical Cost | What It Covers |
|---|---|---|
| Duct inspection and leak test | $100 – $250 | Visual inspection, pressure check, locating leaks and disconnected runs |
| Sealing accessible joints and seams (mastic or foil tape) | $250 – $600 | Sealing leaks at plenum, trunk, and branch connections |
| Sealing entire system with aeroseal-style method | $800 – $1,800 | Sealing leaks from the inside, including runs you can’t easily reach |
| Reconnecting a disconnected flex duct run | $150 – $350 per run | Reattaching and sealing a run that’s blown loose at the boot or plenum |
| Replacing damaged flex duct (per run) | $200 – $450 per run | New insulated flex, properly sized and sealed at both ends |
| Replacing rigid sheet metal trunk or plenum section | $500 – $1,500 | Fabricated replacement, sealed and reconnected |
| Duct insulation replacement | $300 – $900 | Replacing torn or missing insulation on attic runs |
| Full duct system repair and reseal | $1,200 – $2,800 | Multiple runs, trunk line work, and full system sealing |
Most Metairie homeowners end up in the $350 to $1,400 band. The job rarely needs everything on this list. A single disconnected run in a slab or attic system is a quick fix. A home with twenty-year-old flex duct that’s torn, sagging, and leaking at every joint is a bigger project.
What pushes the cost up
- Number of problem runs. One disconnected duct costs a fraction of replacing six.
- Access. Attic runs in a low-pitch Metairie roof are tighter to work in than runs above a drop ceiling.
- Duct material. Rigid sheet metal takes more labor than flex.
- Chase and wall runs. Ducts buried in walls or sealed chases cost more to reach.
- Contamination. If a run has collected mold or heavy debris, cleaning happens before repair.
We clean it, and if it’s broken, we fix it. That’s the whole scope of duct repair as a standalone service. Most duct cleaners clean and leave. We handle the integrity problems cleaning alone can’t touch.
What Affects Duct Repair & Sealing Pricing in Metairie
Cost varies based on your specific house and system. Here’s what shifts the number in Metairie specifically.
- Age of the ductwork. Metairie has a lot of homes built in the 1960s through the 1990s. Ductwork from those decades is often original, meaning the insulation is thin, the connections have loosened, and the flex has started to sag. Older systems tend to need more work.
- Attic heat and humidity. Metairie summers are long and muggy. Attic temperatures climb high enough that poorly insulated ducts lose their cool air before it reaches a register. That heat load is one reason sealing and insulation replacement matter here, sometimes more than in milder parts of the country.
- Slab versus attic systems. A slab-on-grade home with ductwork running through the slab is harder to access than one with an attic system. We can diagnose a slab system, but repair options are more limited and sometimes require rerouting.
- How many leaks. A pressure test shows the total leakage in your system. A system leaking 20 percent versus one leaking 5 percent is a different job with a different price.
- Whether cleaning is needed first. Dust and debris in a damaged system need to come out before we repair, so a combined cleaning and repair visit costs more than repair alone, but solves more.
- Filter contamination. A clogged or missing filter puts more dirt into the ductwork and accelerates wear. We can check your Honeywell, Aprilaire, or Guardsman air-quality components while we’re on site and flag problems.
If your ducts haven’t been inspected in years, the first step is a leak test. That tells us exactly what we’re pricing. Read more about our duct cleaning service and what a full inspection looks like.
How to Save on Duct Repair & Sealing
There’s no magic way to cut this cost without cutting corners, but a few practical moves make a real difference.
- Get the estimate before the work. A written estimate tells you exactly what’s being repaired and what it costs. If someone won’t put it in writing, that’s a problem.
- Combine cleaning and repair in one visit. If you know you need both, do them together. One dispatch fee, one trip, and a cleaner system after the repair is done is cheaper than two separate visits.
- Fix the cause, not just the symptom. A disconnected duct that was never properly sealed will blow loose again. Rigid connections and mastic sealant cost a bit more than tape but last.
- Don’t replace sealed ducts unless you have to. If a chase run is leaking but otherwise sound, sealing it is far cheaper than rerouting it.
- Ask for a free estimate. Call (833) 576-1083. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday. Estimates are free, and the estimate is where you learn what you’re actually paying for.
Why Metairie homeowners call about duct repair
Some of the most common calls we get are about rooms that never cool evenly, registers that blow weak, dust that appears on furniture right after cleaning, and electric bills that creep up for no obvious reason. All four point to the same set of suspects: leaks, disconnects, crushed ductwork, or missing insulation. We diagnose with the equipment first, then price the repair. No guesswork, no “replace the whole system” pitch before we know what’s wrong.
If you’re in Metairie, we can get to you quickly. Our technicians have up to 9 years of experience with attic duct systems, including the ones that are tight, old, and covered in insulation.
Duct Sealing vs. Full Duct Replacement
Most homeowners want to know whether sealing is enough or if the whole system needs to come out. In most cases, sealing plus targeted repair is the right call. But there’s a real cutoff.
If more than about half the ductwork is damaged, crushed, or disconnected, the cost of repairs starts closing in on replacement. Full duct replacement in a Metairie home runs meaningfully higher than repair: typically $3,000 to $7,000 depending on the number of runs and accessibility. That’s not always the better option, and it usually isn’t needed when the underlying runs are still structurally sound.
Here’s the rule of thumb we share with homeowners: if the damage is isolated to a handful of runs, repair and seal them. If the entire system is brittle, sagging, and leaking at nearly every joint, replace it. If you’re somewhere in the middle, we’ll show you both numbers and explain what each gets you.
What Does Duct Sealing Actually Do?
Sealing closes the leaks in your duct system so the air you’re paying to cool and move stays inside the ducts instead of escaping into the attic or wall cavity. It’s a mechanical fix, not a treatment. Mastic, foil tape, or a sealed aerosol method on inaccessible runs all close gaps that leak conditioned air.
The result shows up in a few places. Rooms that never cooled evenly start pulling their weight. Your system runs shorter cycles because it isn’t losing air. The dust that used to appear around registers quiets down. And your electric bill reflects the difference, especially in Metairie’s long cooling season.
Sealing also protects the system itself. Unsealed leaks pull attic air (and attic insulation fibers) into the return side of the system. That debris accelerates filter loading and puts stress on your air handler. If you’ve replaced a filter recently and it’s dark within a month, that’s a sign worth investigating.
When Is Duct Repair an Emergency?
Duct repair is rarely an emergency in the hazard sense, but a few situations need prompt attention: a duct that has collapsed and is partially blocking airflow to the system (which can put pressure on the blower), a duct that has disconnected entirely and is dumping conditioned air into the attic in the middle of summer, or a run that’s pulled loose from a register boot and is blowing debris into a room.
In each of those cases, calling early saves energy and discomfort. We answer 24/7. A call outside dispatch hours is booked into the next opening, Sunday through Friday, 7am to 7pm. We don’t charge extra for same-day work, and same-day service is available when we can fit it in.
FAQs – Duct Repair & Sealing Cost
How much does duct repair cost in Metairie?
Most duct repair jobs in Metairie cost between $350 and $1,400, with an average around $650. Small fixes like sealing a few joints or reconnecting one run sit at the low end. Multiple damaged runs or a full reseal push the total higher. Call (833) 576-1083 for a free estimate.
Is it cheaper to repair or replace ductwork?
Repair is almost always cheaper. Sealing and repairing a few runs runs $350 to $1,400, while full replacement can hit $3,000 to $7,000. Replacement only makes sense when most of the system is damaged. Call (833) 576-1083 and we’ll give you both numbers so you can compare.
How much does duct sealing cost in Metairie?
Sealing accessible joints and seams costs $250 to $600. Full system sealing with an aerosol method runs $800 to $1,800 depending on the size of the system and how many runs need to be sealed. Call (833) 576-1083 for a free estimate.
Can you tell me if my duct system is leaking without pulling it apart?
Yes. We use a pressure test and visual inspection to locate leaks and disconnected runs before we quote anything. That test tells us whether the system is leaking at 5 percent or 20 percent, and it’s the basis for the written estimate. Call (833) 576-1083 to schedule a free estimate.

Duct systems are the part of your HVAC that nobody sees until something stops working. That’s why we lead with equipment: Rotobrush and Nikro are purpose-built systems, not shop vacuums, and Abatement Technologies filtration keeps the work area contained while we’re on site. When the repair side of the job calls for new duct sections, sealing, or a full reseal, we handle that too. One call covers cleaning, venting, and repair.
