Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Duct Sealing Across Jupiter
Duct sealing in Jupiter typically runs $450 – $1,200 for a whole-home system, with most jobs completed in a single visit. We seal supply and return plenums, register boots, and flex-duct connections using mastic and reinforced mesh, not tape that peels in Florida humidity. Call (361) 326-5060 for a free written estimate.
We’ve worked on Jupiter homes from the inlet neighborhoods near the lighthouse to the ranch properties out past Jupiter Farms. Our crews dispatch from the Miami office and carry the full Hollis inventory, so we’re not driving back for parts while your attic sits open. Whether you’re in a 1970s ranch off U.S. Highway 1 with original galvanized takeoffs or a newer stucco home in Abacoa with flex duct in a hot attic, we know what fails here and why.
The Garrison Standard means we arrive inside the quoted window, price the job in writing before touching anything, and leave the site clean. That’s the deal on every call.
Why Hollis Air Duct Cleaning Is Jupiter’s Preferred Duct Sealing Company
Jupiter homeowners have seen enough bait-and-switch pricing to be skeptical of any ductwork quote. We answer that directly: our price is written down before work starts, and it does not move at the door. No per-vent add-ons, no “discovered problems” once we’re inside. The 365-Day Done Right Promise backs every seal we apply. If a seam opens or a collar separates within a year, we return and make it right at no charge, including a free second visit.
Our technicians are background-checked, uniformed, and expected to operate by The Garrison Code on every Jupiter job. They carry professional-grade equipment from Rotobrush and Abatement Technologies, and they explain what they’re doing in plain terms, not jargon. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues.
We know Jupiter’s housing stock. We’ve sealed ducts in 1960s ranch homes near the Jupiter Inlet where salt air has corroded metal collars for decades, and in Mediterranean-style stucco homes in Jonathan’s Landing where slab-on-grade construction pushes duct runs through brutal attic heat. That local knowledge means we diagnose faster and seal to last.
Duct Repair in Jupiter
Duct Repair in Jupiter often starts with damage you can’t see from the living room. In this town, corroded flex-duct collars from salt aerosol exposure, heat-brittled connections in unconditioned attics, and separated seams from years of vibration are the usual culprits behind weak airflow and uneven cooling. We inspect with cameras, mark every failure point, and repair or replace damaged sections before sealing. A typical Duct Repair in Jupiter runs $350 – $850 depending on linear feet of damaged duct and accessibility.
Corroded Collars and Takeoffs
Jupiter’s ocean air carries salt that settles into attic duct runs and roughens metal surfaces. On 1960s-70s ranch homes near the inlet, we’ve found flex-duct collars so corroded that mastic alone won’t bond. We cut back to sound metal, install new collars where needed, then seal with mastic and mesh. Sealing over rusted metal traps moisture; the seam fails again within a season.
Crushed or Collapsed Flex Runs
Flex duct in Jupiter attics gets damaged by storage activity, pest intrusion, or simple heat degradation. We replace compromised sections with properly sized flex, support it to prevent sagging, and seal every connection. A sagging flex run collects condensation in this humidity, which breeds mold and blows musty air into your rooms.
Air Duct Sealing in Jupiter
Air Duct Sealing in Jupiter is the finishing step that makes your HVAC system work the way it was designed. Even a small gap at a register boot or plenum seam leaks conditioned air into your attic, garage, or crawl space, forcing your system to run longer and driving up your FPL bill. We seal with mastic, a water-based compound that remains flexible, reinforced with fiberglass mesh at stress points. Air Duct Sealing in Jupiter typically costs $450 – $1,200 for a whole-home system, with larger homes or complex attic layouts toward the higher end.
Mastic Application at Plenums and Boots
We brush mastic onto every plenum seam, register boot connection, and takeoff joint. In Jupiter’s humidity, tape adhesives fail within months. Mastic cures to a flexible seal that moves with thermal expansion. We apply it thick enough to cover but thin enough to cure properly, then verify with a pressure test where accessible.
Pressure Testing and Verification
After sealing, we check static pressure and airflow at key registers. On one job in Abacoa, sealing a single separated return plenum dropped the system’s static pressure by 0.3 inches and balanced temperatures between the master bedroom and the guest wing. Numbers don’t lie, and we show you the before and after.
Trusted Brands We Service in Jupiter
We stock parts and sealing materials from Aprilaire, Abatement Technologies, and Guardsman, plus we carry Rotobrush equipment for jobs that need rotary brush cleaning before sealing. For Jupiter customers, that means no waiting on a parts run to Miami while your system stays open. We arrive with mastic, mesh, collars, and flex duct in the van. If your system uses Honeywell or Aprilaire filtration components, we can integrate sealing work with filter upgrades in the same visit. Fast turnaround matters in a town where the AC runs ten months a year.
Common Duct Sealing Problems We See in Jupiter Homes
- Salt-aerosol corrosion on 1960s-70s Jupiter Inlet ranch duct collars. The ocean breeze that makes this town pleasant also deposits salt on metal duct components in attic spaces. We regularly find rusted takeoffs where flex duct meets the plenum; sealing over this corrosion without replacing the fitting is a temporary fix that fails before the next cooling season.
- Dust-pollen loading on rural western Jupiter properties from unpaved roads and open land. Homes off limerock roads past Jupiter Farms pull in far more particulate matter than coastal condos. If we seal your ducts but don’t address filtration, the new leaks form at pressure points where dust has abraded the connections. We pair sealing with MERV-rated filter recommendations.
- Wood-heat and outbuilding systems with duct runs through unconditioned sheds or garages. Temperature swings between a hot Jupiter afternoon and a cool evening shear sealant beads that weren’t rated for expansion. We use flexible mastic formulations and proper support to prevent this.
- Post-storm water intrusion in low-lying neighborhoods near the Loxahatchee River. After heavy rain or tropical weather, we find attic ductwork that took water through soffit vents or roof leaks. The flex duct may look intact, but the collar connections have rusted or the duct has sagged from water weight. We dry, repair, and seal to prevent mold bloom.
Pricing for Duct Sealing in Jupiter, FL
A typical whole-home duct sealing in Jupiter runs $450 – $1,200. Small homes with accessible attics and minimal damage fall at the lower end. Larger homes in communities like Jonathan’s Landing, with complex duct layouts through multiple attic zones, run higher. Duct repair adds $350 – $850 if we need to replace corroded collars, crushed flex runs, or water-damaged sections.
What moves the price: linear feet of duct, attic accessibility, extent of corrosion or damage, and whether we need to clean before sealing. We do not quote per-vent prices. One flat price per system, agreed in writing before work starts. You’ll see the number on paper before we open a tool bag.

FAQs About Duct Sealing in Jupiter
Whole-home duct sealing in Jupiter typically costs $450 – $1,200, with duct repair adding $350 – $850 if corroded or damaged sections need replacement. We give one flat price per system in writing before any work begins. Call (361) 326-5060 for a free estimate.
For typical Jupiter homes, every 8 – 12 years is realistic if the original sealing was done properly. Rural properties on unpaved roads west of Jupiter Farms may need attention every 5 – 7 years due to dust loading that abrades connections and forces leaks at pressure points. Coastal homes near the inlet should inspect collars more frequently for salt corrosion.
We seal dryer vent ductwork as part of our dryer vent cleaning service, but the main HVAC duct system is what we address with duct sealing. If your dryer vent run is leaking lint into a wall cavity or attic space, that’s a fire hazard and a separate repair. We can inspect both systems in the same visit and quote each separately.
We photograph every sealed joint with before-and-after images, and we pressure-test the system where accessible to show reduced leakage. Our technicians walk you through the attic or show you the photos on a tablet. The 365-Day Done Right Promise means if a sealed joint fails within a year, we return at no charge.
Jupiter pricing is comparable to Palm Beach Gardens and North Palm Beach, though coastal properties here often need more collar replacement due to salt corrosion, which can push repair costs higher. Rural western Jupiter properties may incur slightly higher travel fees for our Miami-dispatched crews. We quote your specific job in writing before scheduling.
