AfterHow Much Does Duct Repair & Sealing Cost in North Las Vegas?
Duct repair and sealing in North Las Vegas typically runs $350 to $1,200 for most single-family homes, with simple seal jobs at the low end and section replacement or larger leak-prone systems at the high end. Zip-level pricing depends on how much accessible ductwork you have, how many leaks we find, and whether the ducts are flex, sheet metal, or insulated board. A written estimate is the only number that decides the final price, and we give it free.
Here’s what that means in plain terms. If you’re hearing a whistle at the registers, feeling weak airflow in the back bedrooms, or watching dust settle on the furniture faster than it should, a sealing and repair visit usually falls in the $350-$650 band. If a run has collapsed, a trunk line is disconnected, or a section needs replacement, the job climbs toward $900-$1,200 and beyond for larger homes. We quote per job after inspection, not per hour.

Key Takeaways
- Most North Las Vegas duct repair and sealing jobs land between $350 and $1,200, set by a written estimate.
- Leak sealing on an accessible system is the least expensive fix; collapsed or disconnected runs cost more.
- We use Rotobrush brush equipment and Nikro HEPA extraction, plus Abatement Technologies containment gear, so debris is removed rather than redistributed into the house.
- Repair and cleaning can happen in the same visit, which is uncommon among duct cleaners in the valley.
- Estimates are free, and the price is set per job by the written estimate.
Duct Repair & Sealing Cost Breakdown (2026)
The table below shows typical 2026 ranges for the work we do in North Las Vegas. Every job is different, and the written estimate is what sets your price.
| Line Item | Typical Range | What It Covers |
|---|---|---|
| Leak inspection and sealing (accessible flex or sheet metal duct) | $350 – $650 | Locating gaps at joints, collars, and takeoffs; sealing with mastic and mesh tape or foil tape rated for ductwork. |
| Sealing a larger system (multiple runs, attic and crawl access) | $650 – $1,100 | Sealing trunk lines and multiple branch runs, usually requiring more access cuts and more time. |
| Replacing a damaged duct section | $450 – $950 | Cutting out crushed or torn flex, fitting a new section, sealing and re-hanging supports. |
| Reconnecting a disconnected run | $300 – $550 | Re-securing a boot, collar, or branch that has pulled loose from the trunk. |
| Duct cleaning combined with repair (per system) | $500 – $1,400 | Rotobrush brush cleaning and Nikro HEPA extraction, plus sealing or section repair in the same visit. |
| Second system or light commercial add-on | $250 – $700 additional | Homes in North Las Vegas with two HVAC systems, or small commercial spaces, priced as an add-on rather than a second call. |
What pushes a job toward the high end? Access is the big one. Ducts buried under blown insulation in a low attic, or runs squeezed behind drywall, take longer to reach and seal properly. Crushed flex under a floor joist means cutting out and replacing a section rather than sealing it. And a system that’s been leaking for years often has insulation damage along the run, so there’s more to repair than the joint itself.
What keeps a job at the low end? Accessible ductwork, a single system, and leaks that are still at the joint stage rather than full section failure. Homes with a straightforward attic layout and visible flex runs are the quickest to inspect and seal. If you’re comparing bids, ask each contractor whether their price includes the repair or only a cleaning. Those are different line items, and bundling them sometimes costs less than two separate visits.
What Affects Duct Repair & Sealing Pricing in North Las Vegas
Several local and structural factors move the number up or down. Here’s what we see in this market.
- Attic heat and duct condition. Summer attic temperatures in the valley stress flex duct, and insulation jackets break down faster here than in cooler climates. Ducts that sit on the attic floor in direct sun are more likely to have cracked jackets and loosened joints. That heat load is one reason sealing pays for itself in this market, and it’s a factor we weigh when quoting.
- Home age and duct vintage. North Las Vegas has a lot of homes built from the 1990s through the 2000s, and many of them were built with standard flex duct that’s now two or three decades old. Older flex is more brittle, and joints that were taped at install have often lost adhesion. Homes from the 2000s with original ductwork are frequent repair candidates.
- Single system versus dual system. Two-story homes and larger properties often run two HVAC systems. Each system has its own duct network, so pricing moves up accordingly. We price each additional system as an add-on rather than a separate service call.
- Access and layout. Attic access through a small hatch, low clearances, and ducts routed through soffits all add time. A ranch-style home with a wide-open attic is a much faster job than a two-story with cramped mechanical spaces.
- Type of ductwork. Flex duct is cheaper to repair than rigid sheet metal, which may need custom fittings. Insulated duct board falls in between and often needs careful sealing at the board joints. We identify the type during inspection before we quote.
- Whether you combine cleaning with repair. If the ducts are also dirty, combining cleaning and repair in one visit is usually less than scheduling two contractors. We’re set up for that with Rotobrush and Nikro equipment on the truck, and we contain the work area with Abatement Technologies negative-air gear so the rest of the house stays clean.
One point on the equipment side that affects quality, not price: we use a rotating brush system (Rotobrush) paired with Nikro HEPA-rated vacuums. That brush-and-extract approach physically dislodges debris and captures it, rather than blowing it further into the system. Combined with Abatement Technologies containment, it’s the same negative-air and containment discipline used in professional remediation, applied to a residential duct job. If you’re evaluating quotes from different companies, ask what they use. The answer tells you a lot about the result.
How to Save on Duct Repair & Sealing
There aren’t coupons or membership plans here, just practical ways to keep the number reasonable.
- Get the estimate before work starts. We give free written estimates, and the final price is set by that estimate. Call (866) 942-9753 and we’ll schedule a look.
- Combine cleaning and repair. If your ducts are dirty and leaking, one visit is cheaper than two separate contractor trips. It also means the system is cleaned once rather than twice.
- Fix leaks early. A loose collar or a small tear is a sealing job. Left alone, it can turn into a collapsed section, which costs more to cut out and replace.
- Clear the path to the attic. Moving stored boxes and clearing access before we arrive cuts time on the job. It’s a small thing that shows up in the labor portion of the quote.
- Ask about light commercial pricing if you’re a property manager. We serve residential customers and light commercial properties, and bundling units at one address can be more efficient than call-out by call-out.
If your air quality system includes a Honeywell or Aprilaire filtration or humidity component, mention it when you call. Those systems interact with duct condition, and we can talk through the whole picture rather than just quoting a cleaning price.
Why Choose Lancaster Duct Cleaning for Duct Repair & Sealing in North Las Vegas
We’re a focused air duct specialist with exactly three services: air duct cleaning, dryer vent cleaning, and air duct repair. That’s it. No HVAC installs, no handyman work, no general contracting. Keeping the scope narrow is what makes the work worth doing at a professional tier rather than as a side job.
Lancaster Duct Cleaning has served the Las Vegas valley since 2013. That’s 13 years of working on duct systems in the desert heat, which is enough time to know how ductwork behaves here and what a repair actually needs to hold up. We arrive with the same class of equipment serious abatement and restoration pros use, and we name it because it matters: Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman.
If you’re comparing professionals serving North Las Vegas, ask whether they offer duct repair as a standalone service. Many duct cleaners don’t, which means a second contractor when a run is damaged. We clean and repair, one call, one specialist, no second contractor needed.
FAQs – Duct Repair & Sealing Cost
How much does duct sealing cost in North Las Vegas?
Duct sealing in North Las Vegas typically costs $350 to $650 for an accessible single-system home, and $650 to $1,100 for larger systems with multiple runs. The written estimate is the final price. Call (866) 942-9753 for a free estimate.
Is it cheaper to repair ductwork or replace it?
Repair is almost always cheaper than replacement. Replacing a full duct system is a much larger job than most homeowners expect, while sealing and section repair usually falls in the $350-$1,200 range. If a single section has failed, cutting out and replacing that run is far less expensive than redoing the whole network. Call (866) 942-9753 and we’ll tell you honestly which option makes sense for your system.
Can you repair ducts the same day?
Same-day repair is often possible when the job is straightforward sealing or reconnecting a loose run. Larger section replacements or multi-system jobs may need a scheduled return so we can bring the right materials. Call (866) 942-9753 and we’ll tell you what’s realistic for your situation. We answer 24/7, with fast dispatch from 7am to 7pm, Sunday through Friday.
Does duct repair include cleaning?
No, cleaning and repair are separate services, though we can do both in one visit. Cleaning runs $500 to $1,400 depending on system size, and combining it with repair is usually less than scheduling two trips. Our Rotobrush and Nikro HEPA setup lets us clean and inspect in the same pass. Call (866) 942-9753 to price both together.
Are duct repairs covered by insurance?
Homeowner policies sometimes cover duct damage from a covered event like a water leak, but routine wear, rodent damage, and disconnected runs are typically not covered. We can work with your insurer and provide documentation of what we find. For a free estimate on the repair itself, call (866) 942-9753.
How do I know if my ducts need repair or just cleaning?
Signs that point to repair rather than cleaning alone: whistling at registers, rooms that stay hot while others cool fine, visible dust streaks around vents, or a run that’s clearly disconnected in the attic. Cleaning alone won’t fix a leak. An inspection settles it, and the estimate is free.
What Happens When You Call
When you call, we ask a few questions about your home, the system, and what you’re noticing, then book an inspection. We come out, get into the attic or crawlspace, look at the ductwork, and give you a written estimate with line items. Nothing starts until you approve that number. If it’s a repair we can do that day, we do it. If it needs materials we don’t have on the truck, we schedule the return.
The estimate is free and the price is set per job by the written estimate. We answer 24/7, and a call outside dispatch hours is booked into the next opening, Sunday through Friday, 7am to 7pm.
