Our technicians are background-checked and uniformed on every job.

Our Duct Repair & Sealing Services in North Las Vegas
Duct Sealing
Leaky ducts are the single biggest efficiency killer we find in North Las Vegas homes. In the northern ZIPs, 89084 through 89087, original duct sealing from the early 2000s has typically failed after 15-20 years of extreme attic heat. We pressurize the system, locate every leak with precision equipment, and seal with professional-grade mastic or aerosol sealant depending on access and duct type. A typical duct sealing job in North Las Vegas runs $350-$650 for a full system, with partial sealing starting around $180. Every seal is camera-verified before we leave.
Flex Duct Repair
Flex duct dominates the northern North Las Vegas housing stock, and it’s where we spend much of our time. The inner liner degrades in sustained 150°F+ attic temperatures. Joints sag. Insulation compresses. We recently repaired a sagging flex-duct run in a 2004 home near Aliante Parkway (89084). The original mastic seals had cracked from years of attic heat, pulling unfiltered Mojave silica dust into the supply side. We replaced the failing section with insulated flex duct and applied fresh mastic sealant, restoring airflow and reducing airborne particulates. Most flex duct repairs in North Las Vegas range from $220-$480 depending on linear footage and attic access.
Metal Duct Repair
Southern North Las Vegas, particularly the 89030 and 89032 ZIPs, still holds thousands of 1950s-1970s ranch homes with original galvanized metal ductwork. These systems weren’t designed for modern HVAC loads, and uninsulated metal develops condensation in summer that leads to rust, moisture damage, and eventual failure. We repair metal duct by cutting out corroded sections, fabricating replacement pieces, and sealing with professional-grade mastic. Where the original layout is too compromised, we’ll advise honestly on retrofit versus full replacement. Metal duct repair in North Las Vegas typically runs $280-$550.
Duct Insulation
North Las Vegas attics are brutal environments. Even intact ducts lose massive efficiency when insulation degrades. We replace compressed or moisture-damaged duct insulation with new wrap rated for extreme temperature cycling, paying special attention to long attic spans in the northern master-planned communities where builders minimized material costs two decades ago. Duct insulation work in North Las Vegas generally falls between $300-$600 for a full system.

Trusted Brands We Service in North Las Vegas
We stock parts and specify equipment from Abatement Technologies, Rotobrush, and Aprilaire, the same brands serious HVAC contractors use when they want the job to last. For North Las Vegas homeowners, that means faster turnaround. We don’t wait on special orders for standard repairs. Our trucks carry insulated flex duct, mastic sealant, mechanical fasteners, and replacement insulation sized for the duct configurations common in local homes, whether it’s the 6-inch flex typical of 2000s tract construction or the larger metal trunk-and-branch systems in mid-century ranches. When a brand matters to the longevity of the repair, we tell you why. When it doesn’t, we don’t upsell.
Common Duct Repair & Sealing Problems We See in North Las Vegas Homes
- Failed mastic seals in northern ZIPs. In 89084 through 89087, 20-year-old flex-duct systems fail at the joints first, with mastic tape peeling off under extreme attic heat, allowing fine desert dust to bypass filters and accumulate throughout the ductwork. We see this pattern weekly in Aliante and Eldorado homes.
- Rust and condensation in southern metal ducts. Southern ZIPs like 89030 and 89032 still have original metal ducts from the 1950s-70s; these uninsulated ducts develop condensation in summer, leading to moisture damage and rust that compromises duct integrity. The fix is rarely replacement of the entire system, but the damaged sections must be cut out and fabricated anew.
- Heavy particulate loading near the logistics corridor. Technicians working the 89030 and 89081 ZIPs, directly adjacent to the dense industrial and logistics campus corridor along I-15 and Cheyenne Avenue, routinely find abnormally heavy fine-particle and diesel-soot loading in residential ducts that far exceeds what the home’s filter maintenance record would predict. This pattern is specific to North Las Vegas’s warehouse district and doesn’t appear at the same rate in Henderson or Summerlin jobs.
- Sag-and-debris accumulation in long attic runs. The northern communities were built rapidly by volume builders, often with long duct runs across large attic spans that are especially prone to sagging, which traps debris and restricts airflow. We support and re-strap these runs as part of standard repair protocol.

FAQs - Duct Repair & Sealing in North Las Vegas
Most 2004 flex-duct systems in Aliante can be repaired if the damage is localized to joints, sag points, or short degraded sections. We camera-inspect first. If the inner liner is intact across most of the run and the insulation isn’t compressed, targeted repair with fresh mastic sealant and re-strapping typically costs $280-$480 and extends service life 10-15 years. Full replacement becomes the better value only when multiple branches show liner degradation or when the original design has fundamental airflow flaws. Call (844) 685-6342 for a free camera inspection and honest assessment.
North Las Vegas sits in a dust-heavy corridor of the valley where haboob events and active warehouse and logistics construction along the I-15/Craig Road corridor generate above-average airborne particulate loads. If your duct seals have failed, that unfiltered desert air, including fine silica dust and PM2.5, bypasses your filter entirely and recirculates through your home. Summerlin’s older, more established infrastructure and greater distance from industrial corridors means lower baseline particulate, plus its housing stock includes more recent duct replacements. The fix is sealing the leaks, not buying a better filter. We can show you the entry points with our camera.
Original metal ducts in 89030 ranches are absolutely repairable if the rust is localized and the trunk lines are structurally sound. We cut out corroded sections, fabricate replacement pieces from matching gauge metal, and seal with professional mastic. Typical metal duct repair in this area runs $280-$550. Full replacement is only necessary when rust has compromised main trunk lines or when the original layout is so inefficient that repair would leave you with poor airflow and high utility bills. We’ve restored metal duct systems in dozens of 89030 homes that are now performing like new.
The signs are specific: rooms that never reach temperature despite the system running constantly, visible dust accumulation around vent covers, a spike in your summer electric bill, or the smell of hot attic air when the system kicks on. In North Las Vegas, heat-exposed mastic typically fails first at the plenum connection and at joint seams in the attic’s hottest zones, usually the peak areas above the garage or west-facing rooms. We confirm with a pressure test and camera inspection. Call (844) 685-6342 and we’ll show you exactly where the leaks are.
Duct sealing will significantly reduce diesel soot infiltration if your leaks are on the return side or at plenum connections, which is the pattern we see in 89030 and 89081 homes near the I-15/Cheyenne logistics corridor. Sealing alone won’t stop all odor if your home’s envelope has other infiltration points, but sealed ducts eliminate the primary pathway that pulls unfiltered industrial air directly into your HVAC system and distributes it to every room. For homes in this specific area, we recommend duct sealing combined with a thorough cleaning to remove accumulated soot loading. Most sealing jobs in this scenario run $350-$650. Call (844) 685-6342 for a free estimate.
