AfterHow Much Does Duct Repair & Sealing Cost in Boca Raton?
Duct repair and sealing in Boca Raton typically runs $350 to $1,650 for most homes, with small patch-and-seal jobs at the low end and larger duct replacement or full-system sealing at the high end. Sealing alone for a typical attic system usually lands between $550 and $950. The written estimate you get after we look at your ductwork is what sets the final price.
Here’s what a lot of homeowners notice before they call: rooms that never get as cool as the rest of the house, a musty smell when the air kicks on, or visible gaps and sagging runs in the attic. In Boca Raton’s humid climate those small leaks tend to get worse, not better, because moisture finds its way into any opening in the duct system.
We handle repair alongside cleaning, using professional-grade Rotobrush and Nikro equipment. Clean ducts. Repaired ducts. Done right. If you’d rather skip the back-and-forth, call (888) 894-0255 for a free estimate. We answer 24/7, with fast dispatch from 7am to 7pm, Sunday through Friday.
Duct Repair & Sealing Cost Breakdown (2026)
These are typical estimated ranges for the Boca Raton market in 2026. Every duct system is different, so treat these as a starting point. The written estimate you receive after we inspect the ducts is the price that matters.
| Job Type | Typical Range | What It Covers |
|---|---|---|
| Small patch repair (single leak or joint) | $350 – $550 | Sealing one gap or disconnected joint, mastic and tape, minor rework |
| Section repair (damaged run or flex duct section) | $550 – $850 | Replacing a crushed or torn section, reconnecting and sealing the run |
| Duct sealing (whole system, mastic or aerosol) | $550 – $950 | Sealing joints, boots and plenum gaps across the system |
| Repair plus full cleaning (common pairing) | $850 – $1,400 | Rotobrush or Nikro cleaning followed by repair and sealing |
| Full duct replacement (single zone or major section) | $1,200 – $1,650 | New ductwork for a section or zone, plus reconnection and sealing |
The biggest cost driver is access. Ductwork running through a tight attic crawl in a Boca Raton home takes longer to reach and repair than a straight run in an open mechanical closet, and labor reflects that. Material choice moves the number too: flex duct is cheaper to replace than rigid metal, but rigid lasts longer and resists collapse better in a hot attic. Disconnected joints hidden behind drywall or under insulation add time, because the technician has to find and open them first. And if the system also needs cleaning, doing both in one visit is usually cheaper than two separate appointments.
What Affects Duct Repair & Sealing Pricing in Boca Raton
- Attic heat and humidity. Boca Raton’s warm, humid air is tough on duct systems. Flex duct that’s sagged or lost its seal allows condensation and mold growth in the insulation, and that means repair often turns into replacement for the affected section. A system with visible moisture staining usually costs more to fix than one with dry leaks.
- Duct location and access. A single-story home with the air handler in a garage or closet is faster to work on than a two-story home with ducts boxed into soffits. Neighborhoods with older construction styles, like the ranch homes around Boca Del Mar and the townhomes near Camino Gardens, often have tighter attic space than newer builds in western Boca Raton.
- Number of leaks and system size. One disconnected joint is a small job. A system with leaks at every boot, plenum and trunk connection is a whole-system sealing job, and that’s the $550 – $950 range.
- Material type. Flex duct, rigid metal and ductboard each carry different repair labor. Ductboard that’s been wet can’t be resealed reliably and often has to come out.
- Whether you pair it with cleaning. Most leaks aren’t visible until the ducts are cleaned and the technician can actually see the joints. Combining air duct cleaning with repair in one visit usually saves you the cost of a second trip and a second inspection.
- What the leak is doing to your bill. Leaky ducts in a hot attic can push your AC to run longer than it should. Repairing them doesn’t just fix a comfort problem, it can reduce energy waste. This is a good time to mention that our Ashton Air Duct Cleaning team uses the same equipment HVAC professionals trust, from Rotobrush and Nikro cleaning systems to Honeywell, Aprilaire and Abatement Technologies components we service.
How to Save on Duct Repair & Sealing
Get the leaks fixed before they spread. A $350 patch on one joint today is far cheaper than replacing a whole duct section later, and in Boca Raton’s humidity, a small leak rarely stays small. Water gets into the insulation, the duct sags, and now the job is a replacement instead of a repair.
Ask for the estimate in writing with line items. A clear breakdown tells you whether you’re paying for sealing, replacement or both, and it lets you compare apples to apples if you get more than one quote. The written estimate is the price you’ll pay, so don’t accept a verbal range as final.
Pair cleaning with repair when you can. If your ducts haven’t been cleaned in years, doing both in one visit is cheaper than two separate appointments, and the technician can see and fix every joint in the same trip.
- Fix one leak before it becomes a section replacement.
- Combine sealing with a cleaning to save on the second visit.
- Get the estimate in writing, with line items.
- Ask whether the leak is a repair or a replacement. Sometimes a section that looks repairable is too far gone.
- Don’t forget the dryer vent while the technician is there. A dryer vent cleaning is a fire-safety service, and it’s worth asking about in the same visit.
Estimates are free. Call (888) 894-0255 and we’ll set up a time to look at your system.
Why We Handle Repair, Not Just Cleaning
Most duct cleaning companies only clean. If they find a disconnected joint or a crushed run, they tell you to call someone else. That means a second contractor, a second appointment and a second invoice. We handle both, so a single visit can clean the system and fix the leaks the cleaning reveals.
Our technicians have up to 8 years of experience working specifically on ductwork systems, not HVAC in general. That matters for Boca Raton homes, where the combination of attic heat and humidity makes duct condition a real factor in how the house feels and how hard the AC works. We use Rotobrush and Nikro systems to agitate and extract debris, then repair and seal the runs we find. The equipment is professional-grade, and it’s the same equipment HVAC professionals trust.
Air duct cleaning, dryer vent cleaning and air duct repair are the three services we focus on. That focus means the people who show up have worked on duct systems specifically, not a little bit of everything. If you want to understand what a typical Boca Raton service visit covers, we’re happy to walk through it before you book.
Signs You Need Duct Repair Before It Gets Expensive
Catching a leak early is the cheapest way to stay out of the replacement range. Here’s what to look for:
- Uneven cooling. One room runs warm while the rest of the house is fine. That’s often a disconnected or crushed run.
- Visible gaps or sagging in the attic. Duct joints that have pulled apart, or flex duct that’s drooping between hangers.
- Musty or dusty smell when the AC runs. In Boca Raton, this usually points to moisture in the duct insulation.
- Higher electric bills. Leaks let conditioned air escape into the attic, so the system runs longer to keep up.
- Excess dust on surfaces. A leak near a return can pull attic dust into the living space.
If you’re seeing two or more of these, it’s worth having the system checked before the summer cooling season starts. A professional-grade inspection finds the leaks quickly.
What a Typical Repair and Sealing Visit Involves
We start with an inspection of the duct system: the air handler, the plenum, the trunk lines and the branch runs. The technician looks for disconnected joints, crushed sections, torn flex duct, moisture staining and gaps at the boots where ducts meet the registers. In many Boca Raton homes, some of these are visible from the attic access; others need a closer look once the insulation is moved back.
From there, we clean the system if it needs cleaning, then repair and seal the leaks. We use mastic and proper sealing materials for joints, and we replace sections that are too far gone to reseal. When we’re done, you get a clear picture of what was found and what was fixed. If Honeywell or Aprilaire components are part of your system, those can be serviced during the visit too.
Following the visit, we recommend keeping an eye on your cooling bills and comfort for the first month. If something still feels off, call us back and we’ll take another look. Repairing ducts isn’t complicated; finding every leak is the part that takes experience.
Repair or Replace: Which One Makes Sense?
A single damaged section is almost always worth repairing. Full system replacement is usually the right call when the ducts are widespread, wet through the insulation, or made of ductboard that’s been soaked. In a hot, humid climate like Boca Raton’s, water damage in duct insulation is the number one reason a repair turns into a replacement. If the leak is dry and isolated, seal it. If the whole system is wet and sagging, replacing the affected sections is usually the more economical path over the long run.
FAQs – Duct Repair & Sealing Cost
How much does duct repair cost in Boca Raton?
Most duct repair jobs in Boca Raton run $350 to $850, depending on how many leaks, whether a section needs replacing, and how easy the ducts are to reach. Small single-leak patches land at the low end. A crushed run or a damaged section pushes you into the $550 – $850 range. Call (888) 894-0255 for an exact quote. Estimates are free.
Is duct sealing worth the money?
Yes, in most Boca Raton homes it’s one of the best-value fixes you can make. Sealing typically costs $550 to $950, and it stops conditioned air from escaping into the attic. In a hot, humid climate, unsealed joints also let moisture into the duct insulation, which leads to bigger repair bills later. Sealing is the cheaper option compared with repairing water-damaged sections down the road.
How much does it cost to replace ductwork in Boca Raton?
A partial replacement of one zone or major section typically runs $1,200 to $1,650. Full-system replacement in a larger home goes higher, and we’d need to inspect the system to give you a firm number. If you’re seeing widespread moisture damage or ductboard that’s soaked through, replacement is often the right call. Call (888) 894-0255 to schedule an inspection.
Can you fix ducts the same day?
For small patch repairs and simple sealing, yes, same-day service is often possible. Larger jobs, section replacements and full-system sealing may need a scheduled return visit. We answer 24/7 and dispatch from 7am to 7pm, Sunday through Friday. Call (888) 894-0255 and we’ll tell you what we can do for your system.
Should I clean my ducts before or after repair?
Clean first, then repair. Cleaning with Rotobrush or Nikro equipment reveals every joint and gap, so the technician can see the full extent of the leaks. In most Boca Raton homes, doing both in one visit costs less than booking them separately, and it means one pass through the attic instead of two. Call (888) 894-0255 to ask about pairing cleaning with repair.
How can I tell if my ducts are leaking?
Watch for uneven cooling between rooms, a musty smell when the air runs, visible gaps or sagging in the attic, and higher-than-usual electric bills in summer. Any one of these is worth an inspection. Two or more and it’s worth acting before the problem grows. Call (888) 894-0255 for a free estimate.
Ready to Fix the Leaks?
Duct problems in Boca Raton rarely sit still. A small gap in a humid attic gets bigger, the insulation gets wet, and a $350 patch turns into a $1,400 replacement. Getting an estimate doesn’t cost anything, and it gives you a clear number to work from. We’ll look at the system, explain what we find, and put the price in writing.
Call (888) 894-0255 for a free estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday. Clean ducts. Repaired ducts. Done right.
