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.
Fast, Reliable Duct Sealing Across Tequesta
We answer calls for Duct Sealing in Tequesta from crews already working the coastal corridor between Jupiter Island and North Palm Beach, so most homeowners get a technician on-site the same week they call. Salt-laden air off the Loxahatchee River and Indian River Lagoon corrodes flex duct collars and return plenums faster here than anywhere else in Palm Beach County, which means duct sealing isn’t a someday maintenance item in Tequesta, it’s a climate-driven necessity. If your utility bill has climbed without explanation, or rooms near the river side of your home never cool evenly, the problem is likely air leaking through degraded connections before it ever reaches your vents. Call (361) 326-5060 for a free estimate, we’ll price the work in writing before touching anything.
Why Hollis Air Duct Cleaning Is Tequesta’s Preferred Duct Sealing Company
We’ve been driving the A1A corridor and Bridge Road crossings since 2004, long enough to know which Tequesta homes were built with original flex duct in the attic and which neighborhoods see the worst salt corrosion. Our Duct Sealing team has sealed ducts in ranch homes near Tequesta Country Club, in waterfront builds along the Loxahatchee, and in the concrete-block subdivisions off County Line Road where attic temperatures cook tape adhesive off seams in summer.
Tequesta homeowners leave reviews mentioning the same things: our technicians arrive inside the quoted window, in uniform, with the price already written down. No surprises at the door. The 365-Day Done Right Promise covers every sealing job in writing, if a sealed joint fails within a year, we return and make it right at no charge, including a free second visit.
Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops, no callback queues. Scheduling is coordinated from our South Florida office, but crews serve Tequesta locally, not dispatched from three counties away.
Duct Repair in Tequesta
Duct Repair in Tequesta usually means addressing salt-corroded flex duct collars, separated seams in unconditioned attics, or crushed runs from decades of homeowner storage traffic. Most Tequesta homes built between the 1960s and 1980s, particularly in the original Jupiter Inlet Colony and Tequesta Country Club areas, still run original ductwork through attic spaces that hit 140 degrees in July. That heat degrades mastic and tape adhesive, while the area’s year-round humidity swells fiberboard connections until they separate. A typical duct repair in Tequesta runs $280 – $520 for localized fixes, $650 – $1,200 for extensive reworking of multiple runs or replacing corroded plenums.
Corroded Foil Backing Near Coastal Returns
Technicians around Tequesta know to check return ducts near garages and lanais for salt corrosion on the foil backing and for fine green pollen stains, a pattern tied to the area’s combination of coastal salt air and pine or palmetto pollen that inland crews rarely see. We cut out the damaged section and splice in new flex duct with mechanical collars and fresh mastic, not tape alone.
Condensation Damage in Slab-On-Grade Homes
Because so many Tequesta homes are concrete block with slab-on-grade construction, ductwork routes through unconditioned attic space where temperature differentials create condensation. Water pools in low spots, rotting fiberboard or rusting metal connections. We repair the damage and address the underlying airflow imbalance causing the condensation.
Air Duct Sealing in Tequesta
Air Duct Sealing in Tequesta closes the gaps and leaks that let conditioned air escape into your attic, crawl space, or wall cavities before it reaches your rooms. In a coastal climate with constant cooling loads, even a 15% leakage rate forces your AC to run longer, harder, and more expensively. Most Tequesta homeowners notice the problem first as uneven temperatures, rooms near the river side of the house that stay stubbornly warm, or utility bills that spike during pollen season when the system runs overtime. A typical whole-system duct sealing in Tequesta runs $850 – $1,400 for manual mastic and tape sealing of accessible joints, $1,600 – $2,400 when we need to pressurize the system with aerosolized sealant for inaccessible leaks.
Manual Mastic Sealing for Accessible Runs
For homes in The Bluffs and North Passage with newer duct layouts and reasonable attic access, we brush thick mastic compound onto every joint, seam, and collar connection, then reinforce with mesh and a second coat. Mastic remains flexible for decades, unlike tape that dries and cracks in Tequesta’s attic heat.
Aerosol Duct Sealing for Hidden Leaks
When ductwork is buried in soffits or sealed behind drywall, we pressurize the system and introduce an aerosolized sealant that finds and plugs leaks from the inside. The process takes 4 – 6 hours and typically reduces leakage by 80 – 90%, verified with before-and-after pressure tests we show you on-site.
Trusted Brands We Service in Tequesta
Our trucks stock parts and sealing materials from Honeywell, Aprilaire, and Abatement Technologies, the same filtration and ductwork brands found in commercial installations from West Palm to Stuart. We don’t order parts from a warehouse three days away, we carry the collars, mastic, and mechanical fasteners that match Tequesta’s most common duct configurations, original flex runs in 1960s ranches and newer insulated duct in 1990s build-outs. That inventory means most sealing jobs finish in one visit, not two. For homeowners who also want their full system cleaned, we also handle Air Duct Cleaning in Tequesta and Dryer Vent Cleaning in Tequesta, scheduled together or separately.
Common Duct Sealing Problems We See in Tequesta Homes
- Salt aerosol corrosion on return plenums. The brackish air that blows through Tequesta’s riverfront and intracoastal neighborhoods corrodes the foil backing on flex duct and eats through galvanized metal returns. We replace corroded sections with marine-grade materials and seal with mastic rated for coastal humidity.
- Tape failure in unconditioned attics. Original duct tape, the cloth-backed kind, dries to dust in Tequesta’s attic heat within 5 – 10 years. Homes in Tequesta Country Club and Jupiter Inlet Colony built before 1990 almost always need complete resealing with modern mastic compounds.
- Biological growth at condensation points. Year-round humidity means ducts in unconditioned spaces collect moisture at seams and low spots. We seal the leaks that let humid air infiltrate, then address any growth with appropriate remediation before closing the system.
- Crushed flex duct from storage traffic. Tequesta’s slab-on-grade homes route duct through attics that double as storage. We’ve found flattened runs buried under holiday decorations and old patio furniture, choking airflow to entire wings of the house. We repair the damage and reroute where possible to prevent recurrence.
Pricing for Duct Sealing in Tequesta, FL
We don’t quote per-vent teaser prices that balloon once the van is in your driveway. One flat price per system, agreed in writing before work starts, that’s how Hollis operates under The Garrison Standard.

What moves a job toward the higher end: attic accessibility, extent of corrosion damage, need for plenum or flex duct replacement, and whether we find additional leaks during our initial pressure test. What doesn’t move the price: how many vents you have, how long we spend, or whether we need a second trip, that’s on us. Every sealing job includes before-and-after photos of your own ductwork, not stock images, so you see exactly what was leaking and what we sealed. Call (361) 326-5060 for an exact quote, estimates are free.

We seal ducts throughout Tequesta, from the original ranch homes near Tequesta Country Club and Jupiter Inlet Colony to the newer build-outs in The Bluffs and North Passage. Salt corrosion severity varies by proximity to the Loxahatchee River and intracoastal, so we adjust materials accordingly.
Phones are answered by a live person 24/7, and we prioritize calls where a complete duct separation has left a home without cooling in summer heat. True emergencies get same-day or next-day response, scheduled repairs typically within a week.
Tequesta’s coastal climate can add 10 – 20% to repair costs when salt corrosion requires replacing metal plenums or upgrading to marine-grade materials. Manual sealing prices are comparable to West Palm Beach, but aerosol sealing runs slightly higher due to travel logistics for specialized equipment.
Every sealing job is covered by our 365-Day Done Right Promise in writing: if a sealed joint fails within one year, Hollis returns and makes it right at no charge, including a free second visit. No negotiation, no paperwork chase, just a crew back at your door fixing the problem.
