Homes here aren’t like homes elsewhere. The master-planned villages, the multi-zone systems in larger properties, the way 110°F+ attic heat bakes dust into your flexible duct runs – we’ve worked in enough of them to know what fails and why. That’s why we price by the system, not by the vent, and why we put that price in writing before we touch anything.

That promise applies to every home we serve in Summerlin South, from patio homes near The Trails to multi-zone estates in The Ridges.

Air Duct Sealing in Summerlin South

Air Duct Sealing in Summerlin South means finding and closing leaks in your supply and return ductwork, then verifying the repair with pressure testing. Most homes here need it because flexible duct connections degrade in 130-150°F attics, and fine caliche dust works its way into gaps, hardening into a crust that prevents proper airflow. A typical whole-system seal in Summerlin South runs $450 – $850 for a standard single-zone home, $1,200 – $2,400 for multi-zone properties with longer duct runs.

What the Job Actually Covers

We inspect every accessible joint, connection, and seam with a camera. Where we find leaks, we apply duct sealing mastic reinforced with mesh tape – not duct tape, which fails in attic heat. For homes with hardened dust deposits, we use Rotobrush agitation to break the crust before sealing, so the mastic bonds to clean metal or flex core.

When Sealing Beats Replacement

If your ducts are intact but leaking 15-30% of conditioned air into the attic, sealing restores performance without the cost of full replacement. We’ve sealed 20-year-old systems in The Willows that performed like new afterward. We also tell you when ducts are too far gone to seal, because recommending the wrong fix violates The Garrison Standard.

Duct Sealing Services in Summerlin South

Duct Sealing Services in Summerlin South from Hollis include full-system inspection, mechanical agitation of dust deposits, mastic and mesh sealing of all accessible leaks, and post-repair pressure testing to verify results. Homes in newer villages like The Cliffs and Redpoint often contain drywall dust and construction debris from recent builds, while older areas like The Trails and The Willows carry 20+ years of fine desert accumulation. Both conditions require different prep before sealant will adhere. Pricing follows the same per-system structure: $450 – $850 for single-zone, $1,200 – $2,400 for multi-zone.

Multi-Zone Homes Need Multi-Zone Sealing

Many larger Summerlin South properties, especially in The Ridges, run three or more independent zones. Sealing only the leaking zone leaves others dumping conditioned air into the attic. We price each system separately so you know exactly what each costs, and you choose which to address.

Documentation You Can Verify

After our Duct Sealing team finishes, you receive before-and-after photos from the camera inspection, pressure test results showing leak reduction, and your written 365-Day Done Right Promise. You paid for work you cannot see inside your walls. We document it so you know it happened.

Trusted Brands We Service in Summerlin South

We carry Honeywell and Aprilaire filtration components, and our sealing equipment includes Nikro negative-air HEPA systems for dust containment during agitation. For Summerlin South homes with Abatement Technologies filtration installed, we stock compatible replacement parts and can service those units during the same visit. Most repairs don’t require a return trip because our vans carry what the job demands. If you’re in The Vistas or The Paseos and need a specific filter housing or zone damper, we check stock before we dispatch so we’re not wasting your afternoon.

Common Duct Sealing Problems We See in Summerlin South Homes

• Attic heat degrades flexible duct connections. In Summerlin South, attic temperatures regularly hit 130-150°F, causing the adhesive and mechanical ties at flex duct joints to harden and crack. We find leaks at these connections in nearly every home over 10 years old.
• Caliche dust hardens into a sealing barrier. Fine quartz and caliche dust drawn into returns forms a loess-like crust on duct interiors. Sealant applied over this crust fails within months. We use mechanical agitation to break it first.
• Multi-zone systems leak in zones homeowners forget. A three-zone home in The Ridges may have one zone that rarely runs. Those ducts still leak, still waste energy, and still pull dust. We inspect and test every zone, not just the noisy one.
• Newer homes hide construction debris in ducts. Villages like Redpoint and The Cliffs have ducts loaded with drywall dust and wood particles from recent builds. This debris masks leaks during casual inspection and must be removed before proper sealing.
