AfterHow Much Does Duct Repair & Sealing Cost in Reseda?
Duct repair and sealing in Reseda typically costs between $350 and $1,200 for most homes, with minor joint sealing on a handful of runs landing near the low end and partial duct replacement on an older ranch-style house pushing toward $1,800 or more. Sealing alone (mastic and foil-tape work on accessible joints) usually runs $350 to $700. A single crushed flex run replaced with rigid pipe and properly supported comes in around $400 to $800. Whole-house duct replacement is a different project and starts near $2,500.
Those numbers are real-world 2026 Reseda pricing, not national averages recycled from a home-improvement site. The gap between the low and high end almost always comes down to how much of the system is accessible and how badly the original install was done. Call (855) 353-1653 for a free estimate – a technician will measure static pressure and inspect the runs before quoting anything.
Key Takeaways
- Most Reseda duct repair and sealing jobs land between $350 and $1,200.
- Sealing leaks without repairing crushed or disconnected runs wastes money – you have to fix first, then seal.
- Older Reseda housing stock (much of it built in the 1940s through 1970s) often has undersized or uninsulated flex duct that no amount of tape will fix.
- A pressure test before and after tells you whether the work actually delivered, which matters more than the invoice total.
- Free estimates are standard here – get one before you approve any sealing work.
Duct Repair & Sealing Cost Breakdown (2026)
Here’s how the line items break down in Reseda this year. These are installed prices, meaning labor, materials, and cleanup are included.
| Service | Typical Price Range | What It Covers |
|---|---|---|
| Leak sealing (mastic + foil tape, accessible joints) | $350 – $700 | Sealing supply and return joints at the plenum, boots, and reachable trunk connections |
| Full aeroseal-style interior sealing | $900 – $1,800 | Sealing leaks inside the duct system from within, no wall cutting |
| Single run replacement (flex to rigid) | $400 – $800 | Replacing one crushed, torn, or disconnected run with rigid duct, wrapped and supported |
| Partial duct replacement (3 – 6 runs) | $800 – $1,800 | Multiple compromised runs, often attic or subfloor access |
| Duct insulation upgrade (R-8) | $600 – $1,400 | Adding proper R-value insulation to bare or under-insulated ductwork |
| Pressure test (before and after) | $150 – $350 | Measuring system leakage and confirming the job worked |
| Plenum rebuild / transition repair | $450 – $1,000 | Rebuilding a crushed or leaking plenum at the air handler |
| Full duct replacement (whole house) | $2,500 – $6,000+ | Complete removal and reinstall of all trunk and branch runs |
What pushes a job to the high end: attic access in a low-pitch Reseda ranch home where a technician has to crawl through 18-inch clearances, ductwork buried under blown-in insulation, or a system that’s been leaking long enough that the framing around it has moisture damage. What keeps a job low: an accessible crawlspace or garage-installed system, leaks confined to a few joints, and a system that’s otherwise in decent shape.
One thing that surprises a lot of homeowners: repairing and sealing runs in the wrong order costs more. If you seal a crushed run first, you’ve paid for sealing on a duct that still isn’t moving air. The right sequence is inspect, then repair, then seal, then test. If your ducts need repair before cleaning, the Duct Repair & Sealing in Reseda page explains the process we use.
What Affects Duct Repair & Sealing Pricing in Reseda
A half dozen things move the number more than anything else. Each one is worth knowing before you call.
- Access. Reseda has a lot of single-story ranch homes with low-pitch attics, and getting into some of those attics is a real job. A system reachable from a garage or crawlspace takes fewer labor hours than one buried under a foot of insulation in a 100-degree attic. Labor is the bulk of any duct quote, so access is the single biggest variable.
- Age and material of the existing ductwork. Bare sheet-metal duct from the 1950s and 1960s behaves differently than flex from the 1990s. Older metal is often leaky at every joint and needs mastic work throughout. Flex from the 1990s or 2000s is often crushed or torn and needs replacement run by run. Either way, the diagnosis matters more than the material itself.
- Number of compromised runs. One bad run is a small repair. Six bad runs is a partial replacement. The price steps up with each run, but not linearly – there’s a labor economy in doing several at once.
- Leak location and reach. Leaks at the air handler and plenum are easy to reach and cheap to fix. Leaks inside wall cavities or behind drywall require either careful access or an interior sealing method like Aeroseal, which costs more but avoids opening walls.
- Insulation condition. Ducts sitting in a 150-degree attic without proper R-value insulation lose much of the conditioned air before it reaches a room. Adding R-8 insulation isn’t always quoted with repair, but it should be considered if the existing wrap is torn or missing. Reseda’s summer attic temperatures make this a real cost item.
- Whether the system was ever tested. A pressure test (duct leakage test) costs money, but it’s the only way to confirm the work delivered. Skipping it means you don’t know whether the sealing job cut leakage or just looked tidy.
The home page gives a wider view of how this all fits together if you’re new to the company.
How to Save on Duct Repair & Sealing
There’s no way around spending money on a leaky duct system, but a few moves keep the bill lower than it might be.
- Get the diagnosis before the quote. A technician who measures system static pressure and does a room-by-room check finds the real leaks. Quick visual quotes miss the buried ones, and you end up paying for sealing that didn’t address the actual problem.
- Do repair and cleaning in the same visit. Sealing over dust and debris is a bad idea. If the ducts need cleaning anyway, having the work combined in one appointment saves a separate trip charge and lets the technician seal clean joints properly.
- Fix before you replace. Whole-house replacement is expensive. Many systems that look beyond saving just need a handful of runs and a plenum rebuild. Get that option priced before deciding to start over.
- Ask for a before-and-after pressure test. It costs a bit more upfront, but it confirms you got what you paid for. If a contractor can’t or won’t test duct leakage, that’s worth thinking about.
- Address the air handler at the same time. A leaking plenum or a poorly connected air handler loses as much air as several runs combined. Fixing it in one visit reduces repeat labor.
- Ask about the filter setup while you’re at it. Air quality products from Aprilaire and Honeywell can be installed the same visit as repair work, and while it adds to the ticket, it can improve system performance and reduce strain that stresses ductwork over time.

FAQs – Duct Repair & Sealing Cost
How much does duct repair cost in Reseda in 2026?
Most Reseda duct repair jobs run $350 to $1,200, with single-run replacement around $400 to $800 and partial replacement in the $800 to $1,800 range. Whole-house replacement starts near $2,500. Call (855) 353-1653 for an exact quote – estimates are free.
Is it cheaper to repair or replace ductwork?
Repair is almost always cheaper than replacement when the existing system is mostly intact – often half the cost or less. Replacement makes sense when the majority of runs are compromised, when the duct material is degraded throughout, or when the system is undersized for the home. A pressure test and visual inspection tell you which situation you’re in. Call for a free assessment.
How much does duct sealing alone cost in Reseda?
Mastic and foil-tape sealing of accessible joints typically runs $350 to $700, while interior sealing of the whole system (Aeroseal-style) runs $900 to $1,800. Sealing alone won’t fix crushed or disconnected runs, so it’s usually paired with repair. Call (855) 353-1653 to find out which approach fits your system.
Can duct leaks really raise my energy bill that much?
Yes – duct leakage in a typical Reseda home can waste 20% to 30% of conditioned air before it ever reaches a room, which shows up directly on summer bills. Sealing and repairing that leakage often delivers a measurable drop on the next bill. The pressure test is the objective measure. Call for a free estimate and a leakage test.
Can you come out and inspect my ducts today?
We schedule free estimates as quickly as our calendar allows. Call (855) 353-1653 and we’ll get a technician out to assess your system and give you a written quote before any work begins. Upfront pricing, no guesswork.
What equipment do you bring to a duct repair job?
We use Rotobrush rotary brush systems for cleaning the interior of ductwork before repair, Nikro HEPA-filtered vacuums for debris collection, and Abatement Technologies containment equipment to keep dust out of living spaces during the work. Honeywell and Aprilaire filtration products can be installed the same visit if the system would benefit from upgraded filtration.
Does Reseda’s climate make duct problems worse?
It can. Hot, dry summers push attic temperatures well above 130 degrees, and ductwork in those attics takes a beating – flex duct fatigues, insulation wrap deteriorates, and mastic dries out and cracks. Homes built in the 1940s through 1970s in Reseda often have original duct runs that have simply aged out. That’s a big reason we see so many compromised systems in the neighborhood. Call for a free inspection and we’ll tell you what we find.
What’s the best month to schedule duct repair in Reseda?
Spring and early summer are ideal because you get the work done before the heaviest cooling load arrives. Fall works too. The job can be done any time of year, but scheduling before the hot season means you feel the difference in airflow sooner. Call (855) 353-1653 to get on the schedule.
