AfterHow Much Does Duct Repair & Sealing Cost in Hollywood?
Duct repair and sealing in Hollywood typically runs $450 to $1,200 for a standard single-story home, with most jobs landing near $750. Small fixes like resealing a handful of accessible joints sit closer to the low end, while replacing crushed flex runs or reconnecting a detached trunk line pushes toward the top. The written estimate sets the final price, and we give you that estimate for free before any work begins.
We’re Hollywood Duct Cleaning, and duct repair is one of the three things we do – alongside air duct cleaning and dryer vent cleaning. That matters here because a repair price list is only useful if the person quoting it can also tell you whether your ductwork needs cleaning, sealing, or replacement. We bring the same professional-grade equipment to a repair that we bring to a full cleaning: Hollywood Duct Cleaning jobs get the Rotobrush contact-cleaning system, Nikro extraction equipment, and Abatement Technologies air-quality gear. Our technicians have up to 14 years of experience.
Key Takeaways
- Typical duct repair and sealing in Hollywood runs $450-$1,200, with most jobs around $750.
- Leaky joints and disconnected runs are the two most common problems we find – and the two that waste the most cooling.
- Sealing alone is cheaper than repair; repair alone is cheaper than air duct cleaning, but the three often come together.
- Humidity in Broward County makes duct problems worse, not better. A small leak in a hot attic turns into a bigger one fast.
- Estimates are free, and the price is set per job by the written estimate. Call (866) 361-9843. We answer 24/7.
Duct Repair & Sealing Cost Breakdown (2026)
Here’s what the line items look like in the Hollywood market. These are typical estimated ranges, not exact quotes – your written estimate is the real number. We don’t charge a service call fee, and we don’t charge a diagnostic fee.
| Work Item | Typical Range | What It Covers |
|---|---|---|
| Accessible joint and seam sealing | $250 – $550 | Sealing visible gaps at registers, seams, and accessible connections with mastic or foil tape rated for ductwork |
| Full system sealing (whole-house) | $650 – $1,200 | Finding and sealing leaks across the supply and return system, including runs buried in attic insulation |
| Reconnect a detached run | $200 – $450 | Reattaching a boot or flex run that has separated from a trunk or register |
| Replace a crushed or torn flex run | $250 – $600 per run | Removing failed flex duct and installing new, correctly sized and supported duct |
| Rigid duct section replacement | $400 – $900 | Cutting out and rebuilding a damaged section of sheet metal trunk or branch line |
| Trunk line or plenum repair | $500 – $1,400 | Repairing the main distribution trunk after animal intrusion, water damage, or poor original install |
| Register and boot replacement | $120 – $300 per register | New boot, register, and sealed connection where the old one is loose or damaged |
| Repair after pest intrusion | $550 – $1,600 | Removing contaminated or chewed duct, sealing entry points, then cleaning the affected section |
| Duct repair combined with full cleaning | $900 – $2,000 | Repair and Rotobrush contact cleaning in a single visit – usually the better value when both are needed |
The number at the bottom comes from three things: how much duct is actually damaged, how hard it is to reach, and whether cleaning is needed before or after the repair. A leaky joint you can see from the attic hatch is a quick job. A trunk line that a raccoon tore open above a bedroom ceiling is not. We don’t quote from the driveway either – the technician gets into the attic, looks at the actual ductwork, and prices what’s really there.
What pushes a Hollywood job higher than average: older homes with undersized or poorly supported flex runs, attic systems where the ductwork sits in a hot, humid space, and any repair where the duct material itself has failed rather than the connection. What brings it down: accessible joints, a system that only needs sealing, and doing the repair at the same time as scheduled cleaning.
What Affects Duct Repair & Sealing Pricing in Hollywood
Two homes of similar size on the same block can get quotes hundreds of dollars apart. Here’s why.
- Attic conditions. Most Hollywood homes run ductwork through the attic, and attic heat is brutal here. Duct sitting in an attic that hits 130 degrees or more expands, contracts, and loosens at the joints. The hotter and more crowded the attic, the longer the job takes, and time is the biggest cost driver in a repair.
- Humidity and condensation. Broward County’s humid air is hard on duct insulation and on the sealed connections themselves. Duct wrap that stays damp loses its R-value and starts to sag, which puts strain on the joints. If we find wet insulation, we have to address it – repairing the duct and leaving the moisture problem in place just means we’re back next season.
- Duct material and age. Flex duct is fast to repair and fast to replace. Older rigid sheet metal takes more labor because sections have to be cut and fitted. Homes built decades ago often have a mix of both, and that mix costs more to work around.
- Access. A duct run hidden behind drywall needs a different approach than one you can reach from the attic. We’ll always tell you if we’re recommending cutting into a ceiling or wall, and why.
- How many leaks are actually there. A single failed joint is one price. Twelve failed joints across a 20-year-old system is another. We don’t price per joint – we price the whole job – but the scope of the leak problem is the main variable.
- Whether pest intrusion is involved. South Florida attics get visitors. When rats or squirrels get into ductwork, the repair includes removing the contaminated section and sealing the entry point, not just taping the hole shut.
Signs You Need Duct Repair or Sealing (Before You Get a Quote)
You’ll save money on the estimate by knowing what to look for yourself first. These are the signals that a duct repair job is likely, not just a cleaning:
- Rooms that never cool down the same as the rest of the house, especially rooms at the far end of a long run
- Higher electric bills without a change in how you run the AC
- Visible dust blowing out of registers right after you clean them
- Whistling or rattling sounds at the registers when the system starts
- Duct tape peeling or falling off at joints (fabric duct tape fails quickly in Florida attics – it’s a telltale sign of a sealed-in-name-only connection)
- A musty or dusty smell coming from the vents
- An HVAC inspection or home inspection that flagged duct condition
If you’re seeing several of these, it’s worth having the system looked at before the next cooling season starts. You can read more about what a full cleaning involves on our Hollywood page – duct repair and air duct cleaning often happen in the same visit, and combining them usually costs less than booking two separate jobs.
How the Repair Itself Works
A duct repair and sealing job follows roughly this sequence:
- Inspection. We get into the attic, open the access hatch, and look at the actual condition of the ductwork – every run, every connection. If it’s a return-side issue, we check that too.
- Diagnosis. We identify what failed: a loose joint, a crushed run, a torn section, a disconnected boot, or a bad original install. These need different fixes.
- Cleaning, if needed first. If the damaged duct is holding debris or contamination, we clean it before we seal it. This is where the Rotobrush contact-cleaning system comes in – it physically agitates the duct wall surface rather than just passing a vacuum through the opening. Our Nikro extraction equipment maintains negative pressure during the process, so loosened debris doesn’t recirculate into the living space.
- Repair and seal. We rebuild or replace the failed section and seal it properly – mastic or duct-rated tape, code-compliant materials, correctly supported runs.
- Verification. We check airflow at the registers and confirm the repair actually fixed the symptom. If airflow is still weak, there’s another problem to find.
If you’re also thinking about your air handler or filter setup, we service Honeywell, Aprilaire, and Guardsman systems – filtration, air treatment, and duct protection products that work with your existing system rather than against it.
Should You Repair Ductwork or Replace It?
Repair when the duct is sound but the connections have failed – loose joints, separated boots, crushed sections, or torn flex. Replace when the duct material itself is deteriorated: sagging, waterlogged insulation, extensive pest damage, or ductwork that’s undersized for the system. As a rule of thumb, if the repair cost approaches half the cost of replacing the run, replacement is usually the better value over time. We’ll tell you which way the numbers point, and we won’t sell you a replacement for a job a repair can solve.
How to Save on Duct Repair & Sealing
The biggest single saving on a duct job is getting it done early. A loose joint sealed today is a cheap job. The same joint after a season of hot attic air and leaking cooling is a more expensive one. A few practical moves:
- Get the estimate before the cooling season. Spring is when duct problems are easiest to catch and easiest to fix without pressure.
- Combine repair with cleaning. One visit costs less than two. If you’re due for a cleaning anyway, the repair can usually be done at the same time.
- Address the whole leak pattern, not one joint. Sealing one joint in a system with ten leaks doesn’t move your bill. Sealing the system does.
- Ask what the fix actually is. A quote that says “ductwork repair” without naming what’s being repaired is a quote you can’t compare. Ask for the specific scope.
- Check the filter and the return before you pay for anything. A restricted return can look exactly like a duct problem. We’ll check.

Duct Repair vs. Duct Cleaning: What’s the Difference in Cost?
Duct cleaning in Hollywood typically runs $350-$700 for a standard home; duct sealing runs $250-$1,200 depending on scope; duct repair runs $200-$1,600 depending on what failed. They’re different jobs with different prices, and a cleaning won’t fix a leak – it just makes a leaking system cleaner, not tighter. If you’re not sure which one you need, that’s exactly what the free estimate is for.
FAQs – Duct Repair & Sealing Cost
How much does duct sealing cost in Hollywood?
Duct sealing in Hollywood typically runs $250 to $1,200, depending on whether it’s a targeted seal of a few accessible joints (the low end) or a full-system seal that includes runs buried in attic insulation (the high end). The written estimate sets the final price. Call (866) 361-9843 for a free estimate.
Is duct repair worth the money?
Yes, if you’re seeing symptoms – hot rooms, dusty registers, rising electric bills. Leaky or disconnected ducts send conditioned air into the attic instead of the rooms, so the AC runs longer to do the same job. Repairing the duct addresses the cause; a higher thermostat setting only addresses the symptom. Call (866) 361-9843 for a free estimate on your specific system.
How long does duct repair take?
Most duct repair jobs in Hollywood are a single visit, typically a few hours, depending on how many runs are involved and how accessible the attic is. A simple joint seal might take under an hour; a trunk line repair after pest intrusion takes most of a day. We’ll tell you the expected window when we give you the estimate. Call (866) 361-9843 to schedule.
Can duct tape fix a duct leak?
No. Fabric duct tape is the wrong material for ductwork, and in a South Florida attic it fails within a season or two – the heat and humidity break down the adhesive. Proper duct sealing uses mastic or foil tape rated for the application, applied to a clean surface. A tape-and-hope repair is one of the most common things we find and one of the reasons a “fixed” leak comes back. Call (866) 361-9843 for a free estimate on doing it properly.
Will sealing my ducts lower my energy bill?
Usually yes, because sealed ducts put the cooled air in the rooms instead of the attic. How much depends on how leaky the system was and how much of the loss was going into the attic. We can’t quote a percentage – that varies by house – but we can tell you what we find and what the repair will address. Call (866) 361-9843 for a free estimate.
Do you repair ductwork, or only clean it?
We do both. Duct repair is a standalone service for us, not something we refer out. We diagnose and fix compromised ductwork that cleaning alone can’t resolve, using the same Rotobrush and Nikro equipment we use on cleaning jobs. Call (866) 361-9843 to set up an estimate.
