Styles & brands we work with




HVAC Duct Sealing in Anthem
HVAC Duct Sealing in Anthem means finding and permanently closing every leak in your ductwork so the air you pay to heat and cool actually reaches the rooms it’s meant for. In most Anthem homes we inspect, we find multiple leaks at the register boots, plenum connections, and along flex duct runs in the attic. Each leak is closed with mastic sealant and UL-listed foil tape, the two materials that hold up under the extreme attic temperatures we get here.
For Anthem homeowners, sealing typically costs $450 to $1,200 for a single system. Larger two-story homes with multiple zones and extensive flex duct runs fall on the higher end. You’ll get one flat price per system before we begin. No per-vent pricing games, no estimate that changes once the tech is inside.
Camera Inspection Before Sealing
Before we seal anything, we run a camera through your ducts to see exactly where air is escaping. In Anthem homes, we frequently find flex duct connections that were never properly fastened during original construction. We show you the footage. You see what we see.
Duct Blaster Verification
After sealing, we verify with a duct blaster test that measures total system leakage. The goal is under 5% leakage. We test before and after so you know the sealing actually worked, not just that we went through the motions.
Duct Repair in Anthem
Duct Repair in Anthem addresses the physical damage that develops in this specific housing stock: crushed flex runs, disconnected boots, torn outer jackets, and sections of ductwork that have sagged or collapsed under the summer heat. In homes built during Anthem’s 2000s – 2010s build-out, we regularly find connections that were only loosely taped during construction and have since separated entirely.
Repair costs in Anthem generally run $250 to $800 depending on how much ductwork needs replacement versus reconnection. If the damage is limited to re-securing and sealing a handful of connections, you’re on the lower end. If whole flex sections need replacing, the price moves up. Written estimate before we start. Always.
Reconnecting Loose Flex Duct
Flex duct in hot attics expands and contracts with temperature swings. Over years of Anthem summers, connections at register boots and plenum takeoffs work loose. We reconnect, mechanically fasten, and seal each joint so it stays put.
Replacing Crushed or Torn Sections
When ductwork in an attic has been walked on, crushed by stored items, or torn by pests, patching isn’t enough. We replace the damaged section with properly sized flex duct, seal both ends, and restore full airflow to that zone.
Trusted Brands We Service in Anthem
Anthem homes were built with a range of HVAC equipment and duct configurations, and we service all of them. Our sealing and repair work is compatible with the filtration systems many Anthem homeowners already have, including products from Honeywell and Aprilaire. We also use professional-grade testing equipment from Abatement Technologies for duct leakage verification and pressure diagnostics. Because our crews are in Anthem regularly, we keep the common fittings, connectors, tapes, and mastics on the truck, which means most repairs finish the same day without waiting on a parts run.

AfterCommon Duct Sealing Problems We See in Anthem Homes
- Loose flex duct connections at register boots: In Anthem’s tight construction timelines from the 2000s and 2010s, many flex ducts were secured with a single wrap of tape that fails within a few hot summers. Conditioned air pours into the attic instead of your bedroom.
- Duct tape used during original construction: Standard cloth duct tape dries out and peels in Anthem’s attic heat within one season. We remove it and seal properly with mastic and UL-listed foil tape.
- Leaks at the plenum connection: The junction where the main trunk meets the air handler is a common failure point. We see gaps here in homes of every age in Anthem, including ones less than five years old.
- Fine gypsum dust inside return ducts: A signature of Anthem’s fast-paced construction era, drywall dust and insulation particles settled into return ductwork. Sealing alone won’t remove it; that requires cleaning first, then sealing the leaks that keep pulling dust in.

FAQs About Duct Sealing in Anthem
Anthem’s homes were built rapidly during the 2000s – 2010s housing boom, and many flex duct connections were only lightly taped at the factory and never properly sealed during installation. Combined with years of extreme attic heat cycling, those connections loosen and leak. Even homes three to five years old often show measurable leakage. Call (775) 383-5847 and we’ll camera-inspect your system and show you exactly where the leaks are before quoting anything.
In Anthem attics that routinely exceed 130°F in summer, only mastic sealant and UL-listed foil tape hold up long-term. Standard duct tape fails within months. We use mastic on all rigid connections and UL-listed foil tape on flex duct joints, exactly what the trade standard requires for this climate. Ask any bidder what they use; if the answer is duct tape, walk away.
Sealing closes the gaps that pull attic air and construction dust into your ducts, but it won’t remove dust already settled inside. For Anthem homes with the signature fine white gypsum dust in return ducts, the right sequence is cleaning first, then sealing the leakage points. We’ll camera-inspect before recommending anything and show you before-and-after photos of your own ducts. Call (775) 383-5847 to schedule an inspection.
The clearest signs in Anthem homes are uneven temperatures between rooms, an upstairs zone that runs constantly in summer, cooling bills that climb year over year, and dusty registers even after cleaning. You may also hear air whistling in the attic or find rooms that never quite reach the thermostat setting. We’ll confirm with a duct blaster test that measures exactly how much air is escaping. Estimates are free.
Duct sealing and repair in existing homes generally does not require a building permit, though the work should follow the energy code requirements for sealants and leakage testing that apply in the Anthem area. Our sealing methods use mastic and UL-listed foil tape as required by code, and we test to verify leakage under 5% where applicable. We’ll explain what applies to your specific job during the free estimate. Call (775) 383-5847.
