AfterHow Much Does Duct Repair & Sealing Cost in Fort Lauderdale?
Duct repair and sealing in Fort Lauderdale typically costs between $350 and $1,900 for most homes, with the average job landing around $850 to $1,200. Simple repairs like patching a small hole or reattaching a disconnected section run on the lower end, while full-system sealing with mastic and Aeroseal-style treatment pushes toward the top. We give every customer a written price before any work begins, so the number you’re quoted is the number you pay.
This guide walks through 2026 pricing for the Fort Lauderdale market, what drives costs up or down, and how to tell whether a repair is genuinely necessary or if a full replacement makes more sense. If you want a direct answer for your home, call (754) 354-9798 and we’ll walk through what’s going on in your ducts.
Duct Repair & Sealing Cost Breakdown (2026)
Here’s what we see across the Fort Lauderdale metro, from Oakland Park to Plantation to Davie. These are realistic ranges based on the work involved, not national averages from a search engine.
| Service | Typical Cost Range | What It Includes |
|---|---|---|
| Duct inspection & diagnostics | $99 – $250 | Camera or visual inspection of ductwork, leak testing, written findings |
| Small duct patch or seal (1 – 2 joints) | $150 – $400 | Mastic sealing or foil tape, accessible duct sections only |
| Reconnect disconnected duct run | $200 – $500 | Reattaching separated flex duct, resealing with mastic and zip ties |
| Moderate sealing (multiple leaks, 3 – 6 joints) | $400 – $800 | Mastic application across several accessible joints, airflow testing after |
| Full-system duct sealing | $900 – $1,900 | Whole-house treatment, all accessible ducts sealed, pressure testing before and after |
| Duct section replacement (per 10-foot run) | $300 – $650 | Removing damaged or crushed flex duct, installing new insulated run, sealing both ends |
| Plenum repair or replacement | $400 – $1,200 | Repairing or replacing the central box connecting your air handler to branch ducts |
Most Fort Lauderdale homes fall into the moderate range. The single-story ranch homes in Dania Beach and the older mid-century builds in Wilton Manors usually have simpler duct layouts, which keeps labor time down. Two-story homes with ducts running through tight attic spaces add access time, and that shows up in the quote.
Three things move your price within these ranges. First, how many leaks we find. A system with five separate failing joints costs more to seal than one with a single disconnected run. Second, accessibility. Attic ducts in August are a different labor proposition than a crawlspace in February, and technicians working in 120-degree attic heat charge for that time. Third, the condition of the surrounding material. If the duct itself is crumbling, sealing it is throwing money at a lost cause – replacing the section costs more upfront but holds for years instead of months.
What Affects Duct Repair & Sealing Pricing in Fort Lauderdale
- Number of leaks and their location. A single separated joint above a hallway is a quick fix. Eight failing connections spread across an attic floor means more time, more mastic, more labor hours on the invoice.
- Attic size and access. Fort Lauderdale attics run hot year-round. Technicians working in tight, low-clearance spaces take longer, and longer jobs cost more. Homes with walk-in attic access in newer Plantation builds price lower than older sailboat-style attics in Victoria Park.
- Duct material and age. Older flex duct breaks down when the inner liner tears. If your home was built in the 1980s or early 1990s and still has original ductwork, we’re often sealing joints around material that’s nearing end of life. A partial replacement starts to make more sense than repeated patching.
- Whether the air handler is accessible. The plenum connects directly to your AC unit, which in many Fort Lauderdale homes sits in a cramped utility closet or a low attic. Plenum work costs more when the unit is hard to reach.
- Mold or moisture damage. Humidity is a fact of life here. Ducts with visible mold growth or standing condensation need different treatment. Kestrel handles air duct cleaning with HEPA filtration; if the duct material itself is deteriorated beyond sealing, a repair quote will reflect that honestly rather than beating around it.
- Time of year. Summer is peak season for anything AC-related in South Florida. Scheduling flexibility in November or December can mean faster turnaround. Our pricing doesn’t spike seasonally – the written quote is the written quote – but availability shifts.
Repair vs. Replacement: What Actually Makes Sense
Here’s the straight answer we give homeowners in Fort Lauderdale: if your ducts are less than 15 years old and the problem is isolated leaks or separated joints, repair and sealing is the right call. You’ll spend $400 to $1,200, and the system performs like it should. If your ducts are over 20 years old, crumbling, or we’re finding new leaks every visit, replacement stops being an upsell and starts being math.
A full duct replacement in Fort Lauderdale typically runs $3,000 to $7,000 depending on home size and access. That’s a bigger number than sealing. But repeated sealing visits at $500 to $800 a year on failing ducts crosses the break-even point in five to seven years. We’ll tell you which side of that line your ducts are on. The written price for either path is in your hands before work starts, and if sealing fails within 365 days, we come back and fix it at no charge under the 365-Day Done Right Promise.
Dale Whitmore, who leads Kestrel Air Duct Fort Lauderdale, puts it plainly: “If the duct is worth saving, we seal it. If it’s not, we tell you. We’ve talked homeowners out of repair jobs that would’ve failed within the year, and they call us back because of it.”
How to Save on Duct Repair & Sealing
Sealing your ducts isn’t the place to chase the lowest bidder in Fort Lauderdale. A $200 “seal job” usually means foil tape slapped over a visible gap, which fails the next time your AC cycles in July. That said, there are legitimate ways to keep your total down.
- Handle inspection and sealing in one visit. Most companies charge a diagnostic fee, then a separate service fee if they come back. At Kestrel, if we inspect and find leaks we can seal the same day, you’re paying for one visit, not two.
- Bundle with air duct cleaning. If your ducts need cleaning and you’ve got leaks, doing both in one appointment means one setup, one arrival window, one team. We use Rotobrush rotary brush systems to dislodge debris from the duct wall and Nikro negative-pressure units to pull contaminants out, with Abatement Technologies HEPA filtration keeping loosened particles out of your living space. Sealing clean ducts is also more effective: mastic adheres better to surfaces that aren’t coated in years of dust, and the seal lasts longer as a result.
- Seal accessible sections now, plan for the rest. If your attic has a mix of easy-to-reach and hard-to-reach duct sections, we’ll quote them separately. Some homeowners seal the accessible runs first and budget for the rest. You’ll see each line item on the written estimate, so you can decide what fits this month and what waits.
- Ask about the 365-Day Done Right Promise. This isn’t a discount, but it’s real savings. Every Kestrel job comes with a written guarantee that if the work fails within 365 days, we return and make it right at no charge. That’s a free return visit, documented in writing before we start, not a courtesy we might extend. The cheapest quote that requires a second paid visit six months later isn’t cheap.
- Check for disconnected ducts before calling. Walk your attic with a flashlight if you can safely. Disconnected flex ducts are visible – you’ll see a silver tube hanging loose from a round fitting. If that’s your only issue, you’re looking at a $200 to $500 reconnection, not a full-seal job. If you’re not comfortable in the attic space, that’s fine; we’ll do the inspection. But knowing what you’re looking at helps you have a smarter conversation about the quote.

FAQs – Duct Repair & Sealing Cost
How much does it cost to seal ductwork in Fort Lauderdale?
Full-system duct sealing in Fort Lauderdale runs $900 to $1,900, while sealing a small number of accessible joints costs $150 to $400. The difference comes down to how many leaks we’re sealing and how much attic access the job requires. For a written quote on your specific system, call (754) 354-9798 – the estimate is free and the price doesn’t change at the door.
Is duct sealing worth the money?
For most Fort Lauderdale homes, yes. You’ll typically spend $400 to $1,200 on moderate sealing, and the payoff comes in two forms: your AC stops cooling the attic and starts cooling the rooms, and you stop paying to condition air that leaks out before it reaches a vent. The Department of Energy has reported that homes can lose 20 to 30 percent of conditioned air through duct leaks. At $0.12 to $0.16 per kWh from FPL, that lost air is money escaping through your attic. If our sealing fails within 365 days, the Done Right Promise means we fix it free – so the risk is on us, not you.
Can you repair just one section of ductwork?
Yes. If we find one separated joint or a single crushed flex duct run, we’ll quote that section alone, typically $200 to $650 depending on length and location. We won’t push a full-system seal if your problem is isolated. That’s part of the Kingswell Way – say the price, do the work, put the guarantee in writing, and don’t invent problems to inflate the invoice.
How long does duct repair and sealing take?
Small repairs take 1 to 2 hours. Moderate sealing across multiple joints runs 3 to 5 hours. A full-system sealing on a 2,000-square-foot Fort Lauderdale home usually takes 4 to 8 hours, depending on attic conditions and duct layout. We give you a defined arrival window when you book, and the technician works until the job is done, not until the clock hits an arbitrary stop.
What’s the difference between duct sealing and duct replacement?
Sealing costs $150 to $1,900 and fixes leaks in structurally sound ducts. Replacement costs about $3,000 to $7,000 and involves removing old ductwork and installing new insulated runs. If your ducts are under 15 years old and the material is intact, sealing is almost always the right choice. If they’re over 20 years old and showing signs of deterioration, you may be better off replacing sections now rather than paying for repeated sealing visits. We’ll give you an honest read on which path makes sense, and a written price for whichever direction you choose.
Why Fort Lauderdale Homeowners Choose Kestrel for Duct Repair & Sealing
You’ve probably dealt with a contractor who gave a verbal estimate and showed up with a number 40 percent higher. Or one who scheduled a window and arrived four hours late. Or finished the job and stopped answering the phone when something failed. That’s the exact pattern Kestrel Air Duct Fort Lauderdale was built to break.
The Kingswell Guarantee has been the operating standard since 2004, applied identically to every job: a written price before any work begins, a defined arrival window, a clean job site when we leave, and a written guarantee on the work. If it fails within the guarantee period, we return and fix it at no charge. That’s not a promotional promise; it’s the way every Kestrel visit works, and you’ll see it on paper before a single vent is touched.
Our technicians are background-checked and uniformed. They run Rotobrush rotary brush systems to dislodge debris at the duct wall, Nikro negative-pressure units to pull contaminants out, and Abatement Technologies HEPA filtration to keep what we loosen from recirculating through your home. We also carry Honeywell, Aprilaire, and Guardsman filtration and indoor-air-quality products if you want to keep the air clean between professional cleanings.
But maybe the simplest thing: when you call (754) 354-9798, a person answers. Not a voicemail queue. Not an automated system. A real conversation, any time of day or night. If your ducts are leaking and you want to know what it’ll cost to fix, start there. We’ll tell you what we can over the phone, and if you’d like us to take a look, we’ll schedule a time and show up when we said we would.
