AfterHow Much Does Duct Repair & Sealing Cost in Arlington?
Duct repair and sealing in Arlington typically runs $180 to $450 for a small single failure, $400 to $900 for sealing and repairing a run of accessible ductwork, and $1,200 to $3,000+ for extensive repair or partial replacement of a poorly installed system. The final figure is set by a written estimate after we inspect what’s actually in your attic, crawlspace or chase, because two Arlington homes of the same square footage can have completely different duct layouts.
This guide breaks down what each part of the job costs in the Arlington market for 2026, what moves the number up or down, and how to keep the work in the lower half of the range without cutting corners on a system that moves air through every room in your house.
Key takeaways
- Most individual repairs land between $180 and $450; full-run sealing and repair sits at $400 to $900.
- Leaky ducts waste cooling dollars in an Arlington summer, when the system runs long stretches at a time.
- Sealing mastic and mesh on accessible joints costs far less than replacing crushed or disconnected duct sections.
- We use Rotobrush and Nikro equipment and offer repair as a real service, not a referral to someone else.
- Estimates are free. Call (844) 787-8766. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Duct Repair & Sealing Cost Breakdown (2026)
Below are the typical estimated ranges for the work we see across Arlington. These are ranges from the local market, not a quote. The written estimate you get after inspection is the price you pay.
| Service | Typical Estimated Range |
|---|---|
| Sealing accessible joints and seams (mastic and mesh) | $400 – $900 |
| Single section repair (disconnected, torn or crushed flex duct) | $180 – $450 |
| Repair of multiple runs or a full trunk line | $900 – $1,800 |
| Rebuilding a crushed or collapsed section with rigid duct | $350 – $800 per section |
| Replacing damaged flex duct in an attic or crawlspace | $25 – $55 per linear foot installed |
| Repair plus full duct cleaning afterward | $700 – $1,600 |
| Extensive repair and partial replacement | $1,200 – $3,000+ |
What pushes a job toward the top of these ranges? Access, mostly. A disconnected joint four feet inside a walkable attic is a quick fix. The same joint in a low crawlspace under a pier-and-beam floor, or buried under blown insulation, takes longer and costs more. Distance between the air handler and the rooms, the number of separate runs, and whether the duct is flex, sheet metal or ductboard all change the labor. So does the condition of the system: a single torn boot is a small job, while a system where half the joints have never been sealed and one trunk line sags away from its connection is a full afternoon. We don’t add a surcharge for same-day visits; the estimate sets the price, and the estimate is free.
What Affects Duct Repair & Sealing Pricing in Arlington
Arlington sits between Dallas and Fort Worth, and its housing stock reflects that. There are older neighborhoods with pier-and-beam foundations and mid-century duct layouts, and newer subdivisions where flex duct runs through hot attics with little clearance. Both are common repair settings, and each has its own cost profile.
- Attic heat and duct condition. Arlington summers push attic temperatures high enough that aging flex duct gets brittle and the tape and sealant on joints dries out and lets go. Duct that’s spent years cooking in that heat is more likely to need replacement rather than a simple reseal, which moves the job up the range.
- Foundation and access. Pier-and-beam homes in older parts of Arlington often have ductwork in a crawlspace under the floor. That’s a different job than attic work, with different clearance, and it affects labor time. Crawlspace repairs have to account for moisture and pest damage that attic duct doesn’t face.
- Duct material. Sealing metal duct and repairing flex are different tasks. Flex is faster to replace but tears easily; sheet metal lasts but takes more labor to repair and seal. Ductboard sits somewhere in between and is common in older Arlington builds.
- Number of runs and system size. A small house with four supply runs and one return is a smaller job than a two-story home with fifteen runs and multiple zones. More runs mean more joints to seal and more chances for a hidden failure.
- Whether cleaning is needed afterward. A repair often disturbs dust and debris that’s settled in the duct over time. If repair and cleaning are needed together, they can be done on the same visit and typically cost less combined than booked separately.
- Hidden failures. Sometimes the visible problem is small and the real issue is a disconnected joint behind a wall or deep in the attic. Inspection is how we find those, and the estimate reflects what we actually find rather than what the call suggested.
How to Save on Duct Repair & Sealing
The biggest savings come from addressing leaks before they turn into replacements. A sealed joint costs a fraction of a replaced run. Here’s how to keep the figure honest.
- Get the estimate in writing and free. Don’t accept a phone quote on a duct repair. The number depends on what’s actually there, and a written estimate with a fixed price is the only figure that matters.
- Fix all the accessible leaks at once. One visit sealing every reachable joint costs less than three separate visits, because the labor to get into the attic or crawlspace is paid once.
- Pair repair with cleaning when both are needed. If the ducts haven’t been cleaned and a repair is coming anyway, doing both together saves the cost of a second setup and inspection.
- Ask about the return side, not just the supply side. Return duct leaks pull in attic air and dust. Sealing both sides in one job is cheaper than treating them separately.
- Don’t wait for a total failure. A sagging or partially disconnected run that’s losing air now is a $180-$450 repair. Left alone through a few Arlington summers, it can become a section replacement at several times the cost.
- Check the dryer vent while we’re there. It’s a separate system, but scheduling it on the same visit means one dispatch instead of two.

What Does Duct Sealing Actually Do, and Why Does It Matter in Arlington?
Duct sealing closes the gaps, seams and joints in your duct system so conditioned air reaches the rooms instead of leaking into the attic, crawlspace or wall cavity. In Arlington, where the system runs long hours from late spring through early fall, every leak is air you paid to cool that never reached a room. Sealing also keeps attic dust, insulation fibers and crawlspace air from being pulled into the supply side, which is the part of the system that touches the air you breathe.
Sealing isn’t the same as taping. Standard foil tape fails in attic heat and peels off within a few seasons. Professional sealing uses mastic and mesh, or approved sealant, applied to cleaned and prepared surfaces so the joint stays closed. On flex duct, joints are sealed at the collar and at the boot. On metal duct, seams, connections and any place a run passes through framing get the same treatment.
When Is Repair the Right Call, and When Is Replacement Cheaper?
Repair is usually the right call when the duct is structurally sound and the failure is limited to a joint, a boot or one run. Replacement makes more sense when large sections of flex duct have lost their inner liner, when the layout itself is the problem, or when enough sections are failing that sealing the rest won’t fix the system. A duct system that’s crushed, undersized or routed in a way that strangles airflow won’t be saved by sealing it. In those cases, replacing the affected runs costs more up front but less than repeatedly repairing a system that was wrong to begin with. The estimate will lay out both options when both apply, with the price for each, so you can compare directly.
How Long Does Duct Repair Take?
Most single-section repairs take a couple of hours. Sealing an accessible duct system typically takes half a day. Larger repair jobs or partial replacement can take a full day or extend into a second visit, depending on access and how much duct needs work. We’ll give you a time estimate with the written quote so you know what to expect for scheduling. If you’re calling about a system that’s currently blowing poorly or making noise, mention that when you call so it can be booked into the soonest opening.
Can Leaky Ducts Be a Health Issue?
Industry information points to duct leakage as a route for dust, attic insulation particles and crawlspace air to enter the supply system. A well-sealed duct system keeps those particles where they belong. Repairing leaks won’t sterilize a house, and it’s not mold remediation. What it does is close the pathways that allow outside air into the air you breathe and prevent the dust and debris that collects in leaking ducts from being recirculated.
Our Approach to Duct Repair in Arlington
We don’t just clean; we repair. Most duct cleaning companies stop at the brush and vacuum. When they find a tear, a disconnected joint or a crushed section, they refer the client elsewhere, and the leak stays until someone else gets to it. Our scope covers Air Duct Repair as a core service alongside Air Duct Cleaning and Dryer Vent Cleaning. That means the same visit that identifies a failure can usually address it, and the cleaning and repair work that follow are done by the same process rather than handed off.
We use professional-grade equipment: Rotobrush rotary-brush systems and Nikro high-powered vacuum rigs for cleaning, and Abatement Technologies gear for contamination and air-quality remediation work that goes beyond surface dust. Familiarity with brands like Honeywell, Aprilaire and Guardsman means we understand how the air-handler components, humidifiers and filtration interact with the duct system as a whole. Our technicians have up to 12 years of experience, and every job is quoted in writing before work begins.
If you’re looking for duct cleaning or repair in Arlington, the work starts with a look at your actual system. To see everything we handle, visit Paragon Air Duct Cleaning. For details on our local coverage and how we work across Tarrant County, see our Arlington page.
FAQs – Duct Repair & Sealing Cost
How much does duct sealing cost in Arlington?
Sealing accessible joints and seams in an Arlington home typically runs $400 to $900. The range depends on system size, number of runs and how easy the ductwork is to reach. Call (844) 787-8766 for a free written estimate.
How much does a single duct repair cost in Arlington?
A single section repair, such as a disconnected, torn or crushed run, typically costs $180 to $450. Larger multi-run repairs run $900 to $1,800, and extensive repair or partial replacement can reach $1,200 to $3,000 or more. Call (844) 787-8766 for an exact quote from a free estimate.
Is it cheaper to repair ductwork or replace it?
For a limited failure like a disconnected joint or a torn boot, repair is almost always cheaper, usually $180 to $450 against several thousand for a full replacement. Replacement makes more sense when large sections are failing or the layout itself is wrong. The written estimate will show both options when both apply. Call (844) 787-8766 for a free assessment.

Does duct repair include cleaning, and how much does the combined job cost?
Repair and cleaning are separate services, but doing both on the same visit typically costs less than booking them apart, usually in the $700 to $1,600 range. Repair often disturbs settled dust, so cleaning afterward is a natural follow-up. Call (844) 787-8766 for a combined estimate.
